In this appeal, the defendant, Kenneth Lee McCoy, challenges the judgment of the Appellate Court affirming the judgment of conviction rendered after a jury trial of one count of murder in violation of General Statutes § 53a-54a (a). On appeal, the defendant contends that the Appellate Court improperly concluded that (1) he was not deprived of a fair trial due to prosecutorial improprieties, and (2) the trial court properly denied his motion for a new trial for lack of jurisdiction. We disagree but conclude that the form of the trial court's judgment is improper in that the trial court should have dismissed rather than denied the motion for a new trial. Accordingly, we reverse in part the judgment of the Appellate Court and remand the case to that court with direction to render judgment consistent with this opinion.

The following underlying relevant facts and procedural history are set forth in the Appellate Court's decision. "During the fall of 2011, the victim, Dallas Boomer, saw both the defendant and Tramont Murray, his close friends, on a daily basis. The three men often conducted drug deals together out of rental cars .... During November, 2011, the defendant became estranged from both the victim and Murray ....

"On December 6, 2011, at approximately 1 o'clock in the morning, the victim was sitting in the driver's seat of a parked rental car on a residential street in New Haven. Murray was sleeping in the reclined passenger seat. The victim saw the defendant's car pull over to the side of the road and idle nearby, so he shook Murray awake. Murray instructed the victim to drive away. The defendant then approached the victim's parked vehicle with his hand in his sleeve and began shooting at the windshield. The victim attempted to drive away, but could not. Six bullets struck the rental car, and the victim suffered fatal injuries as a result. "Immediately after the shooting, Murray, the sole witness, was questioned by the police. When the police asked Murray to identify the shooter, he stated that he had not seen the shooter .... Three weeks later, on December 27, Murray made a second statement to the police in which he identified the defendant as the shooter. Murray testified consistently with this statement at the defendant's trial." State v. McCoy , 171 Conn. App. 311 , 312-13, 157 A.3d 97 (2017).

After the jury returned its verdict, but prior to the sentencing date, the defendant filed a motion for a new trial. Id., at 323 , 157 A.3d 97 . At the sentencing hearing, the defendant sought to have the motion heard by the trial court; however, the parties and the trial court subsequently agreed to go forward with the sentencing and to hear the motion at a later date. Id., at 323-24 , 157 A.3d 97 . As a result, the sentencing hearing went forward, and the court sentenced the defendant to sixty years incarceration. Id., at 324 , 157 A.3d 97 .

Months after the sentencing, the defendant attempted to have his motion for a new trial heard. Because the defendant's sentence already had been executed, however, the court denied the motion without a hearing on the ground that it had lost jurisdiction. Id. The defendant then appealed from the judgment of conviction, 1 asserting that the prosecutor had engaged in a series of improprieties that deprived him of his constitutional right to a fair trial and that the trial court improperly denied his motion for a new trial for lack of jurisdiction. Id., at 312 , 157 A.3d 97 .

The Appellate Court concluded that, regardless of any improprieties that may have been committed by the state during the trial, the defendant was not deprived of his due process right to a fair trial. Id., at 314-23 , 157 A.3d 97 . The Appellate Court also concluded that the trial court lost jurisdiction once the defendant's sentence was executed and, therefore, that the trial court did not improperly deny the defendant's motion for a new trial. Id., at 323-27 , 157 A.3d 97 . This certified appeal followed. 2 Additional facts will be set forth as necessary.

I

The defendant first claims that the Appellate Court improperly determined that he was not deprived of a fair trial by prosecutorial improprieties committed during his trial. Specifically, the defendant claims that the Appellate Court improperly concluded that the prosecutor did not deprive him of a fair trial when she (1) violated a court order by attempting on three occasions to elicit inadmissible prior consistent statements made by Murray, and (2) asked the jury during closing argument to speculate about the contents of a conversation between Murray and his mother that was not in evidence. In response, the state asserts that the Appellate Court properly concluded that these claimed improprieties did not deprive the defendant of his right to a fair trial. 3 We agree with the state.

With respect to the defendant's claim that the prosecutor thrice violated the trial court's order related to the inadmissibility of Murray's prior consistent statements, the Appellate Court's decision sets forth the following relevant facts. "On the first day of trial, outside the presence of the jury, the prosecutor asked the court whether Murray's second statement to the police, in which he identified the defendant as the shooter, would be admissible as a prior consistent statement. The court responded: 'Well, again, without finally ruling on that, the answer is not necessarily because the rule generally is that when a witness is impeached for a prior inconsistent statement, prior consistent statements are not normally admissible. They can be admissible under the discretion of the court, particularly-and I emphasize particularly-where the prior consistent statement pre-cedes the prior inconsistent statement .... [W]e may have to see what develops, but certainly the answer to what you just said is not necessarily.' The court further stated: 'I haven't given my final rulings on this because I have to see what the witness says on direct, obviously, but I think you must be aware of the general way that I look at this so that you are not surprised, and I think that I have said so.' " (Emphasis omitted.) Id., at 315-16 , 157 A.3d 97 .

During the state's direct examination of Murray, after establishing that Murray had failed to identify the defendant as the shooter in his initial encounter with the police, the prosecutor engaged in the following colloquy with Murray:

" '[The Prosecutor]: Did there come a time about three weeks later when you went back into the police department and gave another statement?

" '[Murray]: Yes.

" '[The Prosecutor]: And in that statement, did you essentially tell the police what you have testified to today in court?

" '[Murray]: Yes.' " Id., at 322 n.4, 157 A.3d 97

Defense counsel did not object to this testimony.

After this testimony, the prosecutor committed the first of the alleged improprieties when she asked: " 'Now, with regard to giving that statement [to the police] on December 27, which is essentially what you spoke about today ....' Defense counsel objected, and the court sustained the objection, noting that '[t]he contents of the second interview should not be divulged further than they already have been without [express] permission of the court. As you know, there are evidentiary rules pertaining thereto.' " Id., at 316 , 157 A.3d 97 . Later, during that same direct examination, the second alleged impropriety occurred when "the prosecutor asked Murray: 'And let me just ask you this: when you spoke to the police again, what did you tell them with regard to who was the shooter?' The court sua sponte excused the jury and addressed the prosecutor, stating: 'I don't know how many times I have told you on the record, and, I believe, explicitly, that ... prior consistent statements are not admissible into evidence unless they precede prior inconsistent statements .... I have told you, with respect to the second interview, on multiple occasions, multiple occasions do not get into the contents.'

"After the prosecutor indicated that she did not think that the court had been explicit in ruling that Murray's prior consistent statements were inadmissible, the court stated that '[u]nder no circumstances without prior permission of the court ... may you ask this witness about any prior consistent statement postdating the original inconsistent statement of December 6. You may not ask him about the substance of that without prior permission of the court, that includes, but is not limited to ... the substance of his statement to the police on December 27. I had thought that I was explicit, but perhaps I was not, and if so, please forgive me.' The court continued, stating: 'I have told you repeatedly not to go there. If you go there again, without prior permission of the court, you are asking-you are basically going to require me to do things that, believe me, I do not want to do. So, don't go there.' " Id., at 316-17 , 157 A.3d 97 .

Finally, the prosecutor engaged in the third alleged impropriety related to prior consistent statements. This impropriety occurred when, "after asking Murray whether he had visited the victim's family the day after the victim's murder, the prosecutor asked: 'With regard to what had occurred with [the victim's] murder, did you tell them what happened?' Defense counsel objected, and the court sustained the objection, instructing the prosecutor to '[a]sk your next question, keeping in mind rulings that the court has already made.' " Id., at 317 , 157 A.3d 97 .

With respect to the claim that the prosecutor improperly referred to facts not in evidence, the factual underlayment is as follows. During the trial, the state presented evidence that Murray's mother encountered Murray crying at his girlfriend's home. The prosecutor asked Murray's mother to describe Murray's demeanor as she spoke to him, and she began to tell the jury what Murray had said to her during that encounter. Defense counsel objected. The court sustained the objection and did not permit Murray's mother to testify about what Murray had said. Then, in closing argument, when referring to Murray's encounter with his mother at his girlfriend's home, the prosecutor argued: " 'They talked, and he told her things, I can't say what they were, but I think you can think about it.' Defense counsel objected, and the court instructed the jury that '[t]his is not in evidence. Do not speculate. That is improper argument.' " Id., at 319 , 157 A.3d 97 .

In analyzing these alleged improprieties, the Appellate Court assumed that the prosecutor had improperly disregarded the trial court's evidentiary rulings related to Murray's prior consistent statements. Id., at 318 , 157 A.3d 97 . As to the prosecutor's closing argument inviting the jurors to speculate about statements not in evidence regarding Murray's conversation with his mother, the Appellate Court determined, consistent with a concession by the state, that this argument was improper. Id., at 319 , 157 A.3d 97 . The Appellate Court concluded, however, that these improprieties did not deprive the defendant of a fair trial. Id., at 320-21 , 157 A.3d 97 .

In the present appeal, the defendant asserts that the Appellate Court improperly concluded that the alleged improprieties did not deprive him of a fair trial. 4 We disagree and conclude that the Appellate Court properly determined that the claimed improprieties did not deprive the defendant of a fair trial. Because the Appellate Court either assumed that these actions of the prosecutor were improper or accepted the state's concession to that effect, we need only address whether the Appellate Court properly concluded that these claimed improprieties constituted a violation of the defendant's right to due process.

We begin with the standard of review. "[T]he touch-stone of due process analysis in cases of alleged prosecutorial [impropriety] is the fairness of the trial, and not the culpability of the prosecutor .... The issue is whether the prosecutor's conduct so infected the trial with unfairness as to make the resulting conviction a denial of due process .... In determining whether the defendant was denied a fair trial [by virtue of prosecutorial impropriety] we must view the prosecutor's comments in the context of the entire trial." (Internal quotation marks omitted.) State v. Campbell , 328 Conn. 444 , 543, 180 A.3d 882 (2018).

''[O]ur determination of whether any improper conduct by the state's attorney violated the defendant's fair trial rights is predicated on the factors set forth in State v. Williams , [ 204 Conn. 523 , 540, 529 A.2d 653 (1987) ], with due consideration of whether that [impropriety] was objected to at trial .... Those factors include the extent to which the [impropriety] was invited by defense conduct or argument ... the severity of the [impropriety] ... the frequency of the [impropriety] ... the centrality of the [impropriety] to the critical issues in the case ... the strength of the curative measures adopted ... and the strength of the state's case." (Citation omitted; internal quotation marks omitted.) State v. Campbell , supra, 328 Conn. at 542 , 180 A.3d 882 .

We consider each of these factors in turn. First, there is no dispute that the comments of the prosecutor were not invited by either the argument or conduct of defense counsel.

Second, we conclude that the claimed improprieties were not severe. With respect to the prosecutor's allegedly improper comments regarding Murray's prior consistent statements, the severity of the alleged improprieties is belied by the fact that Murray's prior consistent statement identifying the defendant as the shooter already had been admitted into evidence without objection. Indeed, the jury already had heard that Murray had given a second statement to the police that was consistent with his testimony at trial. The fact that evidence regarding Murray's prior consistent statement was already admitted into evidence without objection demonstrates both that it was not severe, in that it did not elicit an objection when it was first introduced by the state, and that the impact of the prosecutor's allegedly improper questions was lessened by the fact that the jury had already heard evidence pertaining to that statement.

Moreover, it is important to note that Murray did not answer any of the prosecutor's questions. It is axiomatic that questions are not evidence, only the answers to the questions are evidence. In the present case, the fact that the witness did not answer these allegedly improper questions supports the Appellate Court's conclusion that the alleged improprieties were not severe. Accordingly, we conclude that the severity factor weighs in favor of the state.

With respect to the third factor, namely, the frequency of the impropriety, we conclude that this factor also weighs in favor of the state. The defendant points to three instances in which the prosecutor may have improperly referred to Murray's prior consistent statements, and one instance in which the prosecutor improperly commented on statements not in evidence. Therefore, over the course of a weeklong trial, the defendant claims four instances of prosecutorial impropriety. Thus, we cannot conclude that these improprieties were pervasive.

Fourth, we consider whether the claimed improprieties involved a critical issue in the case. We conclude that the statements made by the prosecutor in the present case did involve a critical issue-namely, the credibility of Murray, the state's key witness and the primary source of evidence used to obtain a conviction of the defendant. Accordingly, we conclude that this factor weighs in favor of the defendant.

With respect to the fifth factor, we conclude that the trial court adopted curative measures in response to the alleged improprieties. In response to the prosecutor's improper comments regarding Murray's prior consistent statements, the trial court sustained each of the defendant's objections and once even interjected, sua sponte, to prevent Murray from answering an inappropriate question. Moreover, the trial court provided an instruction prior to jury deliberations as follows: "[i]t is the answer, not the question or the assumption made in the question that is the evidence."

In connection with the prosecutor's improper reference to facts not in evidence during the closing argument, defense counsel immediately objected and the trial court gave a curative instruction. The court instructed as follows: "Do not speculate on this. This is not in evidence. Do not speculate. That is improper argument." "[W]e have previously recognized that a prompt cautionary instruction to the jury regarding improper prosecutorial remarks or questions can obviate any possible harm to the defendant .... Moreover, [i]n the absence of an indication to the contrary, the jury is presumed to have followed [the trial court's] curative instructions." (Citations omitted; internal quotation marks omitted.) State v. Ceballos , 266 Conn. 364 , 413, 832 A.2d 14 (2003). Therefore, we conclude that the strength of the prompt curative measures weighs in favor of the state.

Finally, we consider the sixth factor, namely the strength of the state's case. We cannot conclude that the state's case was particularly strong. There was limited physical evidence, and no murder weapon was ever recovered. Nevertheless, "we have never stated that the state's evidence must have been overwhelming in order to support a conclusion that prosecutorial [impropriety] did not deprive the defendant of a fair trial." (Internal quotation marks omitted.) State v. Stevenson , 269 Conn. 563 , 596, 849 A.2d 626 (2004). Under the circumstances presented in this case, in which the objectionable evidence already was before the jury, the witness was never permitted to answer the improper questions, and prompt curative instructions were given, we simply cannot conclude that the defendant's right to due process was violated. Accordingly, because the majority of the Williams factors weigh in favor of the state, we conclude that the claimed improprieties in the present case did not deprive the defendant of a fair trial.

II

The defendant next argues that the Appellate Court improperly upheld the trial court's denial of his motion for a new trial on the ground that the trial court lost jurisdiction upon the execution of the defendant's sentence. In particular, the defendant asserts that a trial court continues to have jurisdiction over a criminal matter for four months after judgment pursuant to State v. Myers , 242 Conn. 125 , 136, 698 A.2d 823 (1997), and, therefore, should have ruled on the merits of his timely filed motion for a new trial. The state counters that the Appellate Court properly upheld the trial court's denial of that motion because the trial court lost jurisdiction upon execution of the defendant's sentence. We agree with the state's jurisdictional conclusion. In light of that jurisdictional defect, however, we further conclude that, as a matter of form, the trial court should have dismissed rather than denied the defendant's motion for a new trial.

The following additional facts set forth in the Appellate Court's decision are relevant to the defendant's claim. "On March 18, 2013, one week after the defendant was convicted of murder, he filed a motion for a new trial alleging that the prosecutor had 'continually elicited hearsay statements that the court had precluded by an earlier ruling and offered inadmissible hearsay statements during closing [argument].' ...

"[Subsequently, at] the defendant's sentencing hearing ... defense counsel attempted to argue the defendant's motion for a new trial, but was stymied by the unavailability of the trial transcript. Both defense counsel and the court agreed to postpone arguments until the transcript became available. Defense counsel stated that, so long as the motion was heard at a later date, he did not have a problem going forward with the defendant's sentencing. The court agreed, stating: '[T]he proper way to consider this argument, which ... let me just say I view as colorable ... [i]s to have [defense counsel] file a memorandum with transcript references ... give the state a fair opportunity to file a memorandum of [its] own with transcript references, and then perhaps schedule argument, you know, at a convenient time. Obviously, there are a lot of family members here that are here to see the sentencing, and you're not proposing postponing the sentencing. You're just proposing having the-having the motion for [a] new trial heard at a [later] date.' The court then sentenced the defendant to sixty years incarceration.

"Approximately three months later on September 3, 2013, the defendant amended his motion for a new trial to include a claim that the prosecutor had, in violation of Brady v. Maryland , 373 U.S. 83 , 87, 83 S.Ct. 1194 , 10 L.Ed.2d 215 (1963), failed to disclose consideration given to Murray in exchange for his testimony. On September 20, 2013, the court denied the defendant's motion for a new trial for lack of jurisdiction, citing State v. Luzietti , 230 Conn. 427 , 646 A.2d 85 (1994), for the proposition that a trial court loses jurisdiction over a criminal case once the defendant has been sentenced. As a result, the court did not reach the merits of the defendant's motion." (Footnote omitted.) State v. McCoy , supra, 171 Conn. App. at 323-24 , 157 A.3d 97 .

"The defendant [then] filed a motion for reconsideration, arguing that the court retained jurisdiction under State v. Myers , [supra, 242 Conn. 125 , 698 A.2d 823 ]. The court granted the motion for reconsideration, but again denied the motion for a new trial for lack of jurisdiction, stating that Myers 'does not address the jurisdictional issue.' " State v. McCoy , supra, 171 Conn. App. at 324-25 , 157 A.3d 97 . The Appellate Court affirmed the judgment of the trial court, concluding that the trial court had lost jurisdiction upon execution of the defendant's sentence and, thus, properly denied the motion for a new trial. Id., at 327 , 157 A.3d 97 .

We begin with the standard of review. "Because a determination regarding the trial court's subject matter jurisdiction raises a question of law, our review is plenary." (Internal quotation marks omitted.) Ferri v. Powell-Ferri , 326 Conn. 438 , 448-49, 165 A.3d 1137 (2017). ''The Superior Court is a constitutional court of general jurisdiction .... In the absence of statutory or constitutional provisions, the limits of its jurisdiction are delineated by the common law." 5 (Internal quotation marks omitted.) State v. Parker , 295 Conn. 825 , 834, 992 A.2d 1103 (2010). There is no legislative or constitutional provision governing when a trial court loses jurisdiction following the execution of a criminal sentence; therefore, the issue is governed by the common law. The central issue in the present case is whether the trial court lost jurisdiction upon the execution of the defendant's sentence. To resolve this issue, some context on the jurisdiction of criminal courts relating to sentencing is helpful.

Early case law explains that a court's jurisdiction over a case ends when the term of that court ends. 6 State v. Pallotti , 119 Conn. 70 , 74, 174 A. 74 (1934) ("[t]he established rule is that a sentence in a criminal case may be modified at any time during the term of court at which it was imposed, if no act has been done in execution of it"). More specifically, early cases recognized that, even when the term had not yet ended, the trial court lost jurisdiction when a person had begun to serve his or her sentence. See State v. Vaughan , 71 Conn. 457 , 461, 42 A. 640 (1899) (noting that common-law power of King's Bench to admit bail belongs to Superior Court and ceases when sentence is executed); State v. Henkel , 23 Conn. Supp. 135 , 138, 177 A.2d 684 (Conn. Cir. 1961) ("[w]hile the established rule is that sentence in a criminal case may be modified at any time during the term of court at which it was imposed, such modification cannot be made after an act has been done in execution of it" [internal quotation marks omitted] ); Commonwealth v. Weymouth , 84 Mass. (2 Allen) 144 , 145-46 (1861) (explaining and adopting practice exercised by courts in England that court could modify sentence during court term but could not modify sentence once term was over).

One rationale for this rule was that once sentence was executed, double jeopardy protected a defendant from having his sentence increased. United States v. Benz , 282 U.S. 304 , 307-308, 51 S.Ct. 113 , 75 L.Ed. 354 (1931). Another separate, but related, rationale underlying this rule is the importance of protecting the finality of judgments. See, e.g., Carpentier v. Hart , 5 Cal. 406 , 407 (1855) (reason for rule that court loses jurisdiction when term of court ends "is obvious ... [in that] there must be some finality in legal proceedings, and a period beyond which they cannot extend").

In 1934, this court expressly recognized this common-law rule. In State v. Pallotti , supra, 119 Conn. at 74 , 174 A. 74 , this court explained that "[t]he established rule is that a sentence in a criminal case may be modified at any time during the term of court at which it was imposed, if no act has been done in execution of it. " (Emphasis added.)

Then, in 1962, this court decided Kohlfuss v. Warden , 149 Conn. 692 , 695-96, 183 A.2d 626 , cert. denied, 371 U.S. 928 , 83 S.Ct. 298 , 9 L.Ed.2d 235 (1962), in which this court again noted its approval of the rule in Pallotti , explaining as follows: "Another generally accepted rule of the common law is that a sentence cannot be modified by the trial court, even at the same term, if the sentence was valid and execution of it has commenced .... The reason for this rule has been variously assigned. According to one view, the rule rests on the principle of double jeopardy. According to another view, the rule is based on the proposition that the trial court has lost jurisdiction of the case." (Citation omitted.)

Although we recognized the two rationales for this common-law rule, after Kohlfuss , case law reveals a movement away from double jeopardy as a primary basis for the rule. See Wilson v. State , 123 Nev. 587 , 591-92, 170 P.3d 975 (2007) (explaining Supreme Court's gradual retreat from prohibition against increasing sentence after defendant had begun to serve it and pointing to North Carolina v. Pearce , 395 U.S. 711 , 721, 89 S.Ct. 2072 , 23 L.Ed.2d 656 [1969], which permitted court to impose a more severe sentence after reconviction without violating double jeopardy). Additionally, the concerns related to double jeopardy being one of the animating principles behind this rule have lessened over the years, as the law regarding the ability of courts to modify illegal sentences became clearer. See Benton v. Maryland , 395 U.S. 784 , 89 S.Ct. 2056 , 23 L.Ed.2d 707 (1969) (concluding that concurrent sentences doctrine did not preclude court from exercising jurisdiction over appeal claiming double jeopardy violation).

Nevertheless, the underlying rationale that the rule is supported by the interest in protecting the finality of judgments remains solid. See, e.g., People v. Karaman , 4 Cal. 4th 335 , 348, 842 P.2d 100 , 14 Cal.Rptr.2d 801 (1992) (recognizing common-law rule "that the trial court may change its judgment only during the term in which the judgment was rendered, but not thereafter ... was established in order to provide litigants with some finality to legal proceedings" [citations omitted; footnote omitted] ). Indeed, this court recognized the rule again in 1982, when we reiterated that "[o]rdinarily a sentence may not be modified if any act [has been] done in execution of it." State v. Nardini , 187 Conn. 109 , 123, 445 A.2d 304 (1982).

Notwithstanding this well established rule, in 1986, this court decided State v. Wilson , 199 Conn. 417 , 513 A.2d 620 (1986). In that case, this court addressed whether the trial court could amend its written decision over three years after the defendant was sentenced, in response to a motion for rectification. Id., at 432-34, 513 A.2d 620 . This court explained that "[n]either our General Statutes nor our [rules of practice] define the period during which a trial court may modify or correct its judgment in a criminal case. On the civil side, however, [our rules of practice provide] that any civil judgment or decree may be opened or set aside within four months succeeding the date on which it was rendered or passed. We see no reason to distinguish between civil and criminal judgments in this respect, and we therefore hold that, for purposes of the [common-law] rule, a criminal judgment may not be modified in matters of substance beyond a period of four months after the judgment has become final." (Emphasis omitted; internal quotation marks omitted.) Id., at 437, 513 A.2d 620 ; see also Practice Book § 17-4 ; Practice Book (1978-97) § 326.

Despite making this pronouncement, this court did not use the four month rule to find that the trial court had jurisdiction. Instead, this court concluded that the trial court in that case was without jurisdiction to modify the judgment. State v. Wilson , supra, 199 Conn. at 438 , 513 A.2d 620 . This court explained that "the judgment in this case became final when the defendant was sentenced .... The trial court, when it filed its amended memorandum of decision [over three years later] was clearly without jurisdiction to alter its previous finding ...." Id., at 437, 513 A.2d 620 . Therefore, this court struck the amended memorandum of decision. Id., at 438, 513 A.2d 620 .

Thereafter, in 1994, this court decided State v. Luzietti , supra, 230 Conn. at 431-32 , 646 A.2d 85 . In Luzietti , we addressed whether the trial court had jurisdiction to rule on the defendant's motion for judgment of acquittal, filed six weeks after he began serving his sentence. Id., at 428, 646 A.2d 85 . Despite our decision in Wilson , this court did not deem the trial court to have had continued jurisdiction for four months and, thus, the ability to rule on the defendant's motion postsentencing. Id.

Instead, this court once more reiterated its approval of the traditional rule, stating as follows: ''It is well established that under the common law a trial court has the discretionary power to modify or vacate a criminal judgment before the sentence has been executed .... This is so because the court loses jurisdiction over the case when the defendant is committed to the custody of the [C]ommissioner of [C]orrection and begins serving the sentence." 7 (Citations omitted; footnote omitted.) Id., at 431-32, 646 A.2d 85 . Consequently, because the defendant already had begun to serve his sentence, we held that the court lacked jurisdiction to address his motion.

Three years after Luzietti , in 1997, the court decided State v. Myers , supra, 242 Conn. 125 , 698 A.2d 823 , upon which the defendant in the present case principally relies. In Myers , prior to sentencing, the defendant filed a motion for a new trial, claiming juror bias. Id., at 129, 698 A.2d 823 . Without ruling on the motion for a new trial, the trial court sentenced the defendant. Id., at 131, 698 A.2d 823 . Approximately five months after sentencing the defendant, the trial court ruled on the motion for a new trial. The trial court first granted the defendant's motion for a new trial but subsequently vacated that decision, determining that the defendant's claim should have been brought by way of a petition for a new trial. Id., at 131-32, 698 A.2d 823 . This court reversed the judgment of the trial court, concluding that a motion for a new trial was an appropriate vehicle for a claim of juror bias. Id., at 132, 698 A.2d 823 .

The central point of Myers was that a claim of juror bias had to be addressed in whatever form it was raised. Id., at 139, 698 A.2d 823 . Thus, the defendant's motion for a new trial in that case was appropriate. Id. Although the nature of the claim does not appear necessary to its holding that a motion for a new trial is an appropriate vehicle to alert the court to juror bias, the court made the following statement upon which the defendant seizes: "the trial court retained jurisdiction to entertain the motion for a new trial after sentencing because it could have opened the judgment." (Footnote omitted.) Id., at 136, 698 A.2d 823 , citing State v. Wilson , supra, 199 Conn. at 436 , 513 A.2d 620 .

In Myers , this court neither acknowledged Luzietti nor otherwise discussed any of our well established precedent, including Vaughan , Nardini , Pallotti , or Kohlfuss , holding that a trial court loses jurisdiction upon the execution of the sentence. Instead, in support of its conclusion, this court cited State v. Wilson , supra, 199 Conn. at 436 , 513 A.2d 620 , a case that did not even find jurisdiction under the four month rule it had espoused.

Additionally, a close examination of Myers reveals serious concerns about both its rationale and the implications of its decision were we to follow it without question. Specifically, although this court relied on the four month rule to find that the court had jurisdiction in Myers , the trial court in that case did not rule on the motion for a new trial within four months of the judgment but waited until approximately five months after the judgment to rule on the motion. State v. Myers , supra, 242 Conn. at 131 , 698 A.2d 823 . Myers did not address the fact that the ruling on the motion occurred beyond the four month grant of jurisdiction or, more importantly, under what authority the trial court could rule on a motion five months after the sentencing. The concurring and dissenting opinion in the present case, however, notes the discrepancy but attempts to salvage the reasoning of Myers by focusing on the fact that the motion was filed prior to sentencing. Of course, nothing in Myers states that it was the fact that the motion was filed prior to sentencing that permitted the trial court to exercise jurisdiction beyond the four month period. Furthermore, even if we were to assume that filing the motion prior to sentencing extended the jurisdiction of the court, it certainly would not be extended in perpetuity. Yet that is precisely what Myers and the concurring and dissenting opinion suggest. Indeed, although the court paid lip service to the four month rule in Myers , it actually permitted an extension of five months.

Noting this disparity, the concurring and dissenting opinion further attempts to salvage the rationale of Myers by explaining that this court "not only applied the four month rule, but determined that the trial court retains jurisdiction over a motion for a new trial as long as it was timely filed prior to sentencing, even if the court did not rule on the motion within the four month time frame." By doing so, the concurring and dissenting opinion no longer relies on Myers for its application of the four month rule but seems to assert that, as long as a motion is timely filed prior to sentencing, the trial court retains jurisdiction to modify the sentence at any time to rule on the motion. We disagree.

First, the concurring and dissenting opinion's position is not even supported by Wilson. As explained previously in this opinion, in Wilson , this court suggested that the civil rule that allows trial courts to reopen or set aside civil judgments within four months of judgment applies to criminal cases. Nothing in Wilson or the rule of practice on which that decision relied addresses retaining the limited extension of jurisdiction past a four month period even if the motion was filed before sentencing. Second, if we were to agree with the concurring and dissenting opinion and adopt its reading of Myers , we would essentially give courts an even broader ability to modify criminal judgments than that allowed in civil judgments under the four month rule. We decline to take such a dramatic departure from our well established common law.

Furthermore, over the years following this court's decision in Myers , we consistently have reaffirmed the principle that a trial court loses jurisdiction upon the execution of the defendant's sentence, unless it is expressly authorized to act. See State v. Ramos , 306 Conn. 125 , 134-35, 49 A.3d 197 (2012) ("in criminal cases ... once a defendant's sentence has begun [the] court may no longer take any action affecting a defendant's sentence unless it expressly has been authorized to act" [emphasis omitted; internal quotation marks omitted] ); 8 State v. Parker , supra, 295 Conn. at 835-36 , 992 A.2d 1103 ("a generally accepted rule of the common law is that a sentence cannot be modified by the trial court ... if the sentence was valid and execution of it has commenced" [internal quotation marks omitted] ); State v. Das , 291 Conn. 356 , 361-62, 968 A.2d 367 (2009) (concluding that trial court lacked jurisdiction over defendant's motion to vacate judgment of conviction and to withdraw plea after sentence had been executed and that no constitutional violation exception existed); State v. Lawrence , 281 Conn. 147 , 155, 913 A.2d 428 (2007) (acknowledging established rule that once defendant's sentence has begun, a court may not take action affecting a defendant's sentence unless it expressly has been authorized to act); State v. Reid , 277 Conn. 764 , 774, 894 A.2d 963 (2006) ("In a criminal case the imposition of sentence is the judgment of the court .... When the sentence is put into effect and the prisoner is taken in execution, custody is transferred from the court to the custodian of the penal institution. At this point jurisdiction of the court over the prisoner terminates." [Internal quotation marks omitted.] ); Cobham v. Commissioner of Correction , 258 Conn. 30 , 37, 779 A.2d 80 (2001) ("[t]his court has held that the jurisdiction of the sentencing court terminates once a defendant's sentence has begun, and, therefore, that court may no longer take any action affecting a defendant's sentence unless it expressly has been authorized to act"). As these cases demonstrate, post- Myers , this court has not wavered from the rule that a trial court's jurisdiction is lost upon the execution of the defendant's sentence. By contrast, we cannot find, and the defendant does not point to, any case in which this court has relied on Myers for the proposition that a trial court retains jurisdiction after the defendant's sentence has been executed.

Accordingly, given the long and consistent history of our courts applying the traditional rule that jurisdiction is lost upon the execution of a sentence, we cannot conclude that Myers reflects a retreat from that common-law rule. Instead, we acknowledge that Myers and Wilson are anomalies in this court's case law, and we take this opportunity to clarify and reiterate, as we have consistently done since Myers , that a trial court loses jurisdiction once the defendant's sentence is executed, unless there is a constitutional or legislative grant of authority. State v. Luzietti , supra, 230 Conn. at 431-32 , 646 A.2d 85 . Thus, any reliance on Myers by the defendant to extend the jurisdiction of the trial court beyond the point at which his sentence was executed is misplaced.

In the present case, the defendant's motion for a new trial, although filed before his sentence was executed, was not ruled upon before the sentence was executed. Consequently, the trial court lost jurisdiction. A motion for a new trial-even a timely filed motion that is not ruled upon before sentence is executed-is not a special grant of authority that imbues the trial court with jurisdiction until it is ruled upon. We note that this is an unusual circumstance, and not one that makes us question or need to revisit the well established rule that the court loses jurisdiction upon sentencing. Although we acknowledge that the trial court incorrectly failed to rule on the motion for a new trial before sentencing the defendant, we are mindful of the old adage that bad facts make bad law. Therefore, we refuse to expand the jurisdiction of criminal courts in an effort to address the highly unusual circumstances of the present case.

Indeed, the circumstance this case presents is exceedingly rare and unlikely to recur because a mechanism already exists for trial courts to maintain jurisdiction in this type of situation. Specifically, the court simply could have stayed the execution of the sentence until the motion was heard and ruled upon. To be sure, "[t]he common law has long recognized a court's ability to stay the execution of a criminal sentence" in order to "fulfill its duty to implement the penalties dictated by the legislature for criminal offenses and to promote the ends of justice." Copeland v. Warden , 225 Conn. 46 , 49-50, 621 A.2d 1311 (1993). When the court stays the execution of the sentence, it retains jurisdiction. State v. Walzer , 208 Conn. 420 , 425, 545 A.2d 559 (1988). 9

In the present case, because the trial court did not stay the execution of the defendant's sentence prior to ruling on his motion for a new trial, however, the court lost jurisdiction. The fact that it was not the intent of the court or the parties to do so does not alter the fact that jurisdiction was lost. Jurisdiction does not turn on the intent of the parties or the court. See, e.g., State v. Das , supra, 291 Conn. at 358 , 968 A.2d 367 (denying postsentencing motion to vacate judgment of conviction and to withdraw plea of nolo contendere on ground that trial court lost jurisdiction upon sentencing, and concluding that there is no constitutional violation exception).

Accordingly, the trial court, albeit inadvertently, lost jurisdiction over the defendant's case. Although we observe that this was unintentional, we believe the trial court correctly ruled that "the jurisdictional argument is not a matter of my intent .... [T]he trial court just plain has no jurisdiction. It's not a matter of intent or good faith or bad faith, or anything else. The court just flat out [has] no jurisdiction." 10 The Appellate Court, therefore, properly concluded that the trial court correctly determined that it had lost jurisdiction over the defendant's case when the defendant began serving his sentence. As we explained previously in this opinion, the trial court denied the defendant's motion for a new trial. Given that it lacked jurisdiction, however, it should have dismissed that motion. Therefore, the trial court's judgment is improper in form, and the case must be remanded to the Appellate Court with direction to remand the case to the trial court with direction to dismiss the defendant's motion for a new trial.

III

The defendant next claims that, if the trial court had lost jurisdiction because it sentenced him, then the trial court erred when it sentenced him while his motion for a new trial was pending. Specifically, the defendant asserts that the trial court violated Practice Book § 42-53, which required the trial court to adjudicate his motion for a new trial. The defendant further claims that, by sentencing him before ruling on the motion, the trial court improperly rendered itself unable to adjudicate the motion because it lost jurisdiction.

Practice Book § 42-53 (a) provides: "Upon motion of the defendant, the judicial authority may grant a new trial if it is required in the interests of justice. Unless the defendant's noncompliance with these rules or with other requirements of law bars his or her asserting the error, the judicial authority shall grant the motion: (1) For an error by reason of which the defendant is constitutionally entitled to a new trial; or (2) For any other error which the defendant can establish was materially injurious to him or her." The defendant recognizes that the language of § 42-53 does not expressly require the trial court to rule on all motions for a new trial. Rather, he asserts that the requirement is implicit because it expressly requires that the trial court "shall grant the motion" if certain conditions are met. Practice Book § 42-53 (a).

"It is well settled that [n]ot every deviation from the specific requirements of a Practice Book rule necessitates reversal .... Ordinarily, our courts apply a harmless error analysis in determining whether a violation of a rule of practice amounts to reversible error .... To the extent that a failure to comply with a rule of practice rises to the level of a constitutional violation, [t]he United States Supreme Court has recognized that most constitutional errors can be harmless." (Citations omitted; internal quotation marks omitted.) State v. Ayala , 324 Conn. 571 , 590-91, 153 A.3d 588 (2017).

In the present case, the defendant does not allege that the trial court's alleged failure to comply with Practice Book § 42-53 constitutes a violation of his constitutional rights to due process. Furthermore, on appeal to this court, the defendant did not establish harm that resulted from the trial court's alleged error in failing to adjudicate his motion for a new trial prior to sentencing him. Instead, the defendant merely asserts that the appropriate remedy for the error is to vacate his sentence so that his motion for a new trial can be adjudicated. We disagree. Even if the trial court violated § 42-53, the defendant has failed to explain how or why that violation amounts to reversible error. See, e.g., Adams v. Dept. of Correction , Docket No. M2013-00370-COA-R3-CV, 2014 WL 4536557 , *3 (Tenn. App. September 11, 2014) ("[u]nder circumstances where the pending motions would not have affected the outcome, the over-sight, or failure to rule on pending motions, has been considered harmless error") Thus, because he has not demonstrated harm, we reject the defendant's claim.

IV

Following oral argument, this court requested supplemental briefing, limited to the following question: "If we conclude that the trial court lost subject matter jurisdiction upon sentencing the defendant, is the doctrine of plain error applicable to the trial court's failure to have decided the defendant's pending and timely filed motion for a new trial before it sentenced the defendant?" Thereafter, the defendant argued that the failure of the trial court to rule on his motion for a new trial prior to sentencing constituted plain error that requires vacating his sentence and remanding the case to the trial court to rule on his motion for a new trial. The state contends that the trial court did not commit plain error, because the mistake was neither so obvious nor so harmful as to constitute manifest injustice. We agree with the state.

We begin with the standard of review and applicable law. An appellant cannot prevail under the plain error doctrine "unless he demonstrates that the claimed error is both so clear and so harmful that a failure to reverse the judgment would result in manifest injustice .... It is clear that an appellate court addressing an appellant's plain error claim must engage in a review of the trial court's actions and, upon finding a patent error, determine whether the grievousness of that error qualifies for the invocation of the plain error doctrine and the automatic reversal that accompanies it." (Citations omitted; emphasis in original; internal quotation marks omitted.) State v. Myers , 290 Conn. 278 , 288-89, 963 A.2d 11 (2009).

In the present case, although the trial court delayed hearing the defendant's motion in order to complete the sentencing out of respect for the families of the victim in attendance at the sentencing, we cannot conclude that the trial court had authority to refuse to hear the defendant's motion that was timely filed pursuant to Practice Book § 42-53. See Ahneman v. Ahneman , 243 Conn. 471 , 482, 706 A.2d 960 (1998) ("the trial court lacked authority to refuse to consider the defendant's motions"); Amato v. Erskine , 100 Conn. 497 , 499, 123 A. 836 (1924) ("[i]t is a rule essential to the efficient administration of justice, that where a court is vested with jurisdiction over the [subject matter] upon which it assumes to act, and regularly obtains jurisdiction of the person, it becomes its right and duty to determine every question which may arise in the cause, without interference from any other tribunal" [internal quotation marks omitted] ).

Nevertheless, as we explained in part II of this opinion, a thorough review of our case law demonstrates that the well established rule is that a trial court loses jurisdiction upon execution of the defendant's sentence. We acknowledge, however, that State v. Wilson , supra, 199 Conn. at 436 , 513 A.2d 620 , and State v. Myers , supra, 242 Conn. at 136 , 698 A.2d 823 , were anomalies in our case law and may have resulted in some confusion. Accordingly, although we conclude that it was improper for the trial court to neglect ruling on the defendant's motion for a new trial prior to the execution of his sentence, we do not agree that it was so clear an error as to satisfy the first prong of the plain error doctrine.

In any event, even if that error were deemed to be clear, the defendant's claim of plain error fails on the second prong-namely, whether the error is "so harmful that a failure to reverse the judgment would result in manifest injustice." (Internal quotation marks omitted.) State v. Myers , supra, 290 Conn. at 289 , 963 A.2d 11 . The defendant contends that the trial court's failure to decide his motion for a new trial constitutes manifest injustice because the opportunity to have a trial court review that motion was a unique opportunity and that any other avenue for review would be inadequate. The state argues that the defendant was not harmed by the trial court's failure to review his motion for a new trial because there were other avenues for the defendant to have his claims resolved and, more generally, that a trial court's failure to comply with a rule of procedure is not enough, by itself, to necessitate reversal for plain error. We agree with the state.

We certainly acknowledge the benefits of having the trial judge, as opposed to a reviewing court, decide the motion for a new trial in the first instance. See State v. Smith , 313 Conn. 325 , 347, 96 A.3d 1238 (2014) ("[a]ppellate review of a trial court's decision granting or denying a motion for a new trial must take into account the trial judge's superior opportunity to assess the proceedings over which he or she has personally presided" [internal quotation marks omitted] ). Under the circumstances of the present case, however, we simply cannot conclude that the trial court's failure to rule on the defendant's claims was an error so harmful that it resulted in manifest injustice.

In his motion for a new trial, the defendant raised the claim that the prosecutor engaged in impropriety by attempting to elicit previously precluded hearsay and by referring to statements not in evidence during closing arguments. These are some of the same issues that the defendant raised as stand-alone claims of prosecutorial impropriety on direct appeal. Indeed, the Appellate Court and now this court have reviewed the merits of those claims of impropriety and both courts have concluded that the defendant was not deprived a fair trial. 11 See State v. McCoy , supra, 171 Conn. App. at 314-23 , 157 A.3d 97 ; see also part I of this opinion. In other words, the prosecutorial impropriety claims raised in the defendant's motion for a new trial themselves have no merit. We therefore cannot conclude that the trial court's failure to review those claims equates to an error so harmful that it was a manifest injustice necessitating reversal pursuant to plain error review. The concurring and dissenting opinion concludes that "the manifest injustice in this case is not necessarily that the defendant would have prevailed on his claims, but rather that the parties and this court have lost the benefit of the trial court's considered views of his claims, especially in light of the fact that the trial judge deemed the defendant's motion for a new trial 'colorable.' " 12 Anytime a trial judge fails to rule on a motion, we are deprived of the trial court's views. That, however, does not by definition result in reversible error. We might agree that the trial court's failure to rule on the defendant's motion in this case could be an error, but that error in itself does not satisfy the separate and distinct prong of the plain error test. "As we have explained ... the defendant also must demonstrate, under the second prong of the plain error test, that the omission was so harmful or prejudicial that it resulted in manifest injustice .... This stringent standard will be met only upon a showing that, as a result of the obvious impropriety, the defendant has suffered harm so grievous that fundamental fairness requires a new trial." (Citation omitted.) State v. Jamison , 320 Conn. 589 , 598-99, 134 A.3d 560 (2016).

As with any error that is not structural-and there is no claim here that the court's failure to rule on the motion for a new trial is structural-a defendant must demonstrate how the error harmed him. As with any trial court error in which we must engage in an analysis of harm, we are either deprived of the trial court's considered decision or we are reviewing an erroneous decision. We then must take that nonexistent or erroneous ruling and consider the effect that it had on the conviction. In the plain error context, the error must be so harmful as to amount to a manifest injustice requiring a new trial. State v. Myers , supra, 290 Conn. at 289 , 963 A.2d 11 .

To assess the harm, we must look at the substance of the motion to see if it has any merit. Indeed, it would be truly bizarre if a court's failure to rule on a meritless or frivolous motion for a new trial could amount to an error so harmful that a manifest injustice has occurred. That circumstance is what we are presented with here-lack of a ruling on a meritless motion. As we have explained previously in this opinion, the defendant's motion sought a new trial based on the prosecutor's attempts to elicit a prior consistent statement from a witness. We already have found that that claim lacks merit. See part I of this opinion. Indeed, the concurring and dissenting opinion agrees with this conclusion. Thus, unlike the concurring and dissenting opinion, we cannot conclude that the failure to get the trial court's "considered views" of a motion that so obviously lacks merit was an error so harmful that a manifest injustice has occurred.

We are also guided by this court's decision in State v. Myers , supra, 290 Conn. 278 , 963 A.2d 11 . In that case, the defendant appealed from a judgment of conviction for possession of narcotics. Id., at 280-81, 963 A.2d 11 . On appeal, the defendant alleged that the trial court committed plain error when it did not comply with Practice Book § 42-2 by not affording the defendant a hearing regarding his repeat offender status. Id., at 284-85, 963 A.2d 11 . The Appellate Court agreed, observing that a failure to comply with "applicable rules of practice" was, per se, plain error. (Internal quotation marks omitted.) Id., at 285, 963 A.2d 11 .

On appeal to this court, we observed as follows: "Although we agree with the Appellate Court that the trial court's failure to comply with the procedures of Practice Book § 42-2 was clearly improper, we conclude that the Appellate Court abused its discretion in vacating the defendant's sentence because the [trial court's] error ... did not 'result in manifest injustice.' ... Indeed, apart from the trial court's failure to comply strictly with the applicable rule of practice, which we do not condone, the defendant has failed to raise any doubt with respect to the validity of his prior conviction. A trial court's failure to comply with a rule of criminal procedure, without more, is insufficient to require reversal for plain error." (Citation omitted; emphasis in original; footnote omitted.) Id., at 289-90, 963 A.2d 11 .

Similarly, although we do not condone the trial court's failure to rule on the motion for a new trial before sentencing the defendant without a stay of execution, its failure to do so, without more, is insufficient to require reversal for plain error. Indeed, in the present case, as in State v. Myers , supra, 290 Conn. 278 , 963 A.2d 11 , the defendant has failed to raise any doubt with respect to the validity of his conviction, particularly when we have had the opportunity to review, and reject, the very claims of prosecutorial impropriety raised in his motion for a new trial.

Furthermore, we agree with the state that there are other avenues by which a defendant may address such claims of prosecutorial impropriety. For instance, a defendant could (1) pursue a direct appeal from his or her conviction, as the defendant did in the present appeal, or (2) file a petition for writ of habeas corpus.

The defendant further contends that his other claim within the motion for a new trial, namely, the claim that the state violated Brady v. Maryland , supra, 373 U.S. 83 , 83 S.Ct. 1194 , should be addressed by the trial court because the trial court is in a unique position to understand the intricacies of the present case. We are not persuaded.

First and foremost, as the state points out, the defendant's Brady claim was only added to his motion for a new trial three months after his sentence was executed. As a result, the trial court already had lost jurisdiction over the motion. Consequently, the trial court never had jurisdiction over this claim.

Second, although it is true that this court has recognized the importance of the trial judge's "superior opportunity to assess the proceedings over which he or she has personally presided"; (internal quotation marks omitted) State v. Smith , supra, 313 Conn. at 347 , 96 A.3d 1238 ; this does not mean that the trial court is the only court that can review a Brady claim. Indeed, this court has regularly entertained claims of Brady violations that were not distinctly raised at trial, as long as those claims satisfied Golding. 13 See, e.g., State v. Jordan , 314 Conn. 354 , 369-76, 102 A.3d 1 (2014) ; State v. Ouellette , 295 Conn. 173 , 185-87, 989 A.2d 1048 (2010). Moreover, as the Appellate Court noted in the present case, newly discovered Brady claims may also be brought by way of a petition for a new trial up to three years after sentencing. State v. McCoy , supra, 171 Conn. App. at 328 n.6, 157 A.3d 97 ; see also General Statutes § 52-270. Therefore, we cannot conclude that the trial court's failure to review the defendant's Brady claim constitutes manifest injustice. Accordingly, we conclude that the defendant is not entitled to have his sentence vacated pursuant to the plain error doctrine.

The judgment of the Appellate Court is reversed insofar as that court affirmed the trial court's denial of the defendant's motion for a new trial, and the case is remanded to the Appellate Court with direction to reverse that ruling and to remand the case to the trial court with direction to dismiss the defendant's motion; the judgment of the Appellate Court is affirmed in all other respects.

In this opinion ROBINSON, C.J., and KAHN and VERTEFEUILLE, Js., concurred.

D'AURIA, J., with whom, PALMER and McDONALD, Js., join, concurring in part and dissenting in part.

A jury found the defendant, Kenneth Lee McCoy, guilty of murder. The defendant filed a motion for a new trial within the time prescribed by Practice Book § 42-54, raising grounds that the trial court described as "colorable ...." The court scheduled its consideration of the motion for the same day as the defendant's sentencing. Upon beginning to hear argument on the motion, however, the court determined that a trial transcript was necessary and, therefore, continued the hearing on the motion to allow for the transcript's preparation and for the state to file a brief. Both parties consented.

However, to avoid inconveniencing the victim's family, which was in court that day, the trial court conducted the defendant's sentencing proceeding. This, in the words of the Appellate Court, was a "collective mistake"; State v. McCoy , 171 Conn. App. 311 , 328 n.6, 157 A.3d 97 (2017) ; because it implicated the rule that "the trial court loses jurisdiction upon sentencing ...." (Citations omitted.) Id., at 327 , 157 A.3d 97 . The import of this rule was not raised until the state, with a further extension of time, filed its brief opposing the defendant's motion for a new trial. Upon discovering this collective mistake, the trial court agreed with the state that it lacked jurisdiction to rule on the motion and denied it.

Like the Appellate Court, the majority today concludes that nothing can be done about what it concedes was an "unintentional" or "inadvertent" loss of jurisdiction over a timely filed motion for a new trial. I find the court's application of this rule in the present case to prevent a ruling on the defendant's motion so illogical that I cannot believe our law compels this result. In fact, it does not. Rather, there are in my view exceptions to this rule that permitted-in fact, required-the trial court to retain jurisdiction over the defendant's motion for a new trial, which was timely filed prior to sentencing. These exceptions fall within the scope of our existing case law. To the extent that they do not, I believe that under this court's inherent authority to develop the common law, this court should adopt a sensible exception to avoid such an illogical result. Finally, even in the absence of any exception, I would conclude that it was plain error for the trial court not to have ruled on the motion for a new trial before sentencing, and I would reverse the judgment of the Appellate Court and remand the case to that court with direction to remand the case to the trial court with direction to rule on that motion-a simple solution that I cannot fathom our law does not permit. I therefore respectfully dissent. 1

I

This court has articulated the rule at issue in the present case in this way: "It is well established that under the common law a trial court has the discretionary power to modify or vacate a criminal judgment before the sentence has been executed ... [but] the court loses jurisdiction over the case when the defendant is committed to the custody of the commissioner of correction and begins serving the sentence." (Citations omitted.)

State v. Luzietti , 230 Conn. 427 , 431-32, 646 A.2d 85 (1994). The parties and the majority take it as a given that this rule, which the trial court concluded prevented it from ruling on the defendant's timely filed motion for a new trial, implicates the trial court's subject matter jurisdiction. Although our case law is not clear that this rule implicates subject matter jurisdiction, for purposes of this discussion I will not quarrel with that proposition. 2

Most of our case law concerning the subject matter jurisdiction of the courts concerns the interpretation of statutes, i.e., whether the legislature has conferred jurisdiction on the courts or limited the jurisdiction of the courts. When a statute seeks to create or expand the court's jurisdiction, we narrowly construe the statute. See Spears v. Garcia , 263 Conn. 22 , 28, 818 A.2d 37 (2003) (statute that creates cause of action that was not available at common law is strictly construed); H-K Properties, LLC v. Planning & Zoning Commission , 165 Conn. App. 488 , 500, 139 A.3d 787 ("to substantially expand appellate jurisdiction, we must construe the statute strictly in accordance with its terms"), cert.

granted on other grounds, 322 Conn. 902 , 138 A.3d 932 (2016) (appeal withdrawn August 5, 2016). When a statute seeks to limit the court's common-law jurisdiction, however, we strictly construe that statute as well so as to limit jurisdiction only to the extent expressly and explicitly stated by the legislature. See Sastrom v. Psychiatric Security Review Board , 291 Conn. 307 , 324-25, 968 A.2d 396 (2009) (explaining that legislature knows how to expressly limit scope of jurisdiction and if no intent to limit is expressed, then statute does not divest court of jurisdiction). This latter rule of construction is consistent with the general rule that the court's common-law general jurisdiction is broad and that "there is a strong presumption in favor of jurisdiction ...." (Citations omitted.) State v. Ramos , 306 Conn. 125 , 134-35, 49 A.3d 197 (2012). If we interpret a court's statutory jurisdiction too broadly or too narrowly, the legislature can direct the judiciary differently. See Hall v. Gilbert & Bennett Mfg. Co. , 241 Conn. 282 , 297, 695 A.2d 1051 (1997) ("the legislature [may instruct] us that we have misconstrued its intentions" [internal quotation marks omitted] ).

The rule under consideration in the present case, however, does not implicate the legislative creation, exclusion, or limitation of the court's jurisdiction-subject matter or otherwise. Rather, as the majority acknowledges, we grapple with a principle of common-law jurisdiction, and specifically, a rule concerning when a court loses common-law jurisdiction it indisputably had-here, the jurisdiction to rule on a timely filed posttrial motion for a new trial, a motion which derives from the common law. See Zaleski v. Clark , 45 Conn. 397 , 404 (1877). In a situation such as this, it is the courts that define the contours of their common-law jurisdiction over a common-law motion, not the legislature. See State v. Parker , 295 Conn. 825 , 834, 992 A.2d 1103 (2010) ("The Superior Court is a constitutional court of general jurisdiction .... In the absence of statutory or constitutional provisions, the limits of its jurisdiction are delineated by the common law." [Internal quotation marks omitted.] ). Therefore, the contours of this jurisdictional rule are defined by the decisions of this court, based on experience and sensibility, rather than by a mechanical application of rules without reason. See O. Holmes, The Common Law (P. Pereira & D. Beltran eds., 2011) p. 5 ("The life of the law has not been logic: it has been experience .... The law ... cannot be dealt with as if it contained only the axioms and corollaries of a book of mathematics."). 3 As is obvious from our most recent case law, this court has struggled with defining the sensible contours of this common-law jurisdictional rule. Any rule, however, must account generally for the "strong presumption in favor of jurisdiction"; State v. Ramos , supra, 306 Conn. at 133-35 , 49 A.3d 197 ; 4 and specifically for the courts' broad common-law jurisdiction to preside over criminal cases. State v. Carey , 222 Conn. 299 , 305, 610 A.2d 1147 (1992) ("[t]he Superior Court hearing a criminal matter acquires subject matter jurisdiction from its authority as a constitutional court of unlimited jurisdiction" [internal quotation marks omitted] ). Also as a general principle, the court has the inherent authority to modify its own judgments. See State v. Dayton , 176 Conn. App. 858 , 871 n.13, 171 A.3d 482 (2017) ("[o]ur courts have inherent power to open, correct and modify judgments" [internal quotation marks omitted] ). Historically, this includes the authority to grant a motion for a new trial, which is a "common law power [that] the courts ... have the right to exercise in such a manner as shall best promote justice." Zaleski v. Clark , supra, 45 Conn. at 404 .

In State v. Wilson , 199 Conn. 417 , 436-38, 513 A.2d 620 (1986), this court ruled that the trial court was without jurisdiction to modify or correct a judgment, in other than clerical respects, three years after the defendant's sentence. In determining the outside limits of the timing by which a trial court could modify a judgment, we recognized that "[n]either our General Statutes nor our Practice Book rules define the period during which a trial court may modify or correct its judgment in a criminal case. On the civil side, however, Practice Book § [17-4] provides that any civil judgment or decree may be opened or set aside 'within four months succeeding the date on which [notice] was [sent].' " (Emphasis omitted.) Id., at 437, 513 A.2d 620 . We therefore borrowed this four month rule and extended it to judgments in criminal cases, explaining that there was ''no reason to distinguish between civil and criminal judgments in this respect, and we therefore hold that, for purposes of the common law rule, a criminal judgment may not be modified in matters of substance beyond a period of four months after the judgment has become final." Id. We concluded, however, in Wilson , that even with an extension of the four month rule, the trial court clearly had exceeded its jurisdiction by attempting to amend the judgment three years after sentencing. Id.

Subsequently, in State v. Luzietti , supra, 230 Conn. 427 , 646 A.2d 85 , without overruling or even discussing Wilson , this court held that in criminal cases, "once judgment has been rendered and the defendant has begun serving the sentence imposed, the trial court lacks jurisdiction to modify its judgment in the absence of a legislative or constitutional grant of continuing jurisdiction." Id., at 431, 646 A.2d 85 . In Luzietti , the defendant's sentence had been stayed pending the disposition of his motion for a judgment of acquittal. Id., at 429, 646 A.2d 85 . The trial court denied the motion and the defendant began serving his sentence. Id. Six weeks after he had begun serving his sentence, the defendant filed a motion to reargue the motion for a judgment of acquittal, which the trial court granted and then held a hearing. Id., at 429-30, 646 A.2d 85 . At the hearing, the state argued that the trial court could not grant the motion for a judgment of acquittal because it did not have jurisdiction to vacate the judgment of conviction after the defendant began serving his sentence. Id., at 430, 646 A.2d 85 . The trial court disagreed and granted the motion. Id. The state appealed to the Appellate Court, which held that the trial court lacked jurisdiction to grant the defendant's motion for a judgment of acquittal because it could not modify the judgment after the defendant had begun serving his sentence. Id. In affirming the judgment of the Appellate Court, this court relied on the rule that "the [trial] court loses jurisdiction over the case when the defendant is committed to the custody of the commissioner of correction and begins serving the sentence," absent a statutory or constitutional grant of jurisdiction. Id., at 432, 646 A.2d 85 .

Then, in State v. Myers , 242 Conn. 125 , 698 A.2d 823 (1997), without even mentioning the common-law rule at issue, this court held that the trial court retained jurisdiction to rule on a motion for a new trial filed before sentencing but considered and ruled on after sentencing. Id., at 136, 698 A.2d 823 . In Myers , prior to sentencing, the defendant had filed a motion for a new trial on the ground of juror bias. Id., at 129, 698 A.2d 823 . Before ruling on the motion, the trial court sentenced the defendant without staying the sentence. Id., at 131, 698 A.2d 823 . Approximately five months later, the trial court granted the motion for a new trial; id. ; but later vacated its order, determining that it could not rule on the motion after the defendant had been sentenced and that the juror bias claim should have been raised in a petition for a new trial, not in a motion for a new trial. Id., at 136, 698 A.2d 823 . Citing to Wilson , but without more, this court reversed the judgment of the trial court, explaining that "the trial court retained jurisdiction to entertain the motion for a new trial after sentencing because it could have opened the judgment." (Footnote omitted.) Id.

Consistent with our existing case law, there are in my view at least two paths to concluding that the trial court in the present case did not lack jurisdiction over the defendant's timely filed motion for a new trial: (1) because our holdings in Wilson and Myers permit the trial court to hear and rule on a timely new trial motion filed before sentencing or (2) because the exception for mutual mistake applicable in civil cases should apply in this case. 5 At any rate, I have heard no compelling argument that should prevent this court from developing or modifying this common-law rule, which we have the inherent power to do, to recognize an exception to the general axiom for timely motions for a new trial filed before sentencing. A

There is no dispute that the trial court in the present case originally had jurisdiction to decide the motion for a new trial: "The Superior Court hearing a criminal matter acquires subject matter jurisdiction from its authority as a constitutional court of unlimited jurisdiction .... The Superior Court's authority in a criminal case becomes established by the proper presentment of the information ... which is essential to initiate a criminal proceeding .... [U]pon the return to the Superior Court of the indictment [or information] against the accused, it obtained the sole and original jurisdiction of the charge therein made ...." (Citations omitted; internal quotation marks omitted.) State v. Carey , supra, 222 Conn. at 305-306 , 610 A.2d 1147 ; see State v. Ramos , supra, 306 Conn. at 133-34 , 49 A.3d 197 (" 'The Superior Court is a constitutional court of general jurisdiction. In the absence of statutory or constitutional provisions, the limits of its jurisdiction are delineated by the common law.' "). Thus, this case does not in my view require us to expand the court's jurisdiction, as the majority suggests. Rather, the question is whether the court inalterably lost jurisdiction it unquestionably had, pre-venting it from ruling on the timely filed motion.

The rule at issue is the product of common law; it is a common-law exception to the court's inherent authority to open, correct, and modify judgments. See State v. Dayton , supra, 176 Conn. App. at 871 n.13, 171 A.3d 482 ("[o]ur courts have inherent power to open, correct and modify judgments" [internal quotation marks omitted] ). The common law is judge made law. See Western Union Telegraph Co. v. Call Publishing Co. , 181 U.S. 92 , 102, 21 S.Ct. 561 , 45 L.Ed. 765 (1901) ("the common law comprises the body of those principles and rules of action ... which derive their authority ... from the judgments and decrees of the courts" [internal quotation marks omitted] ). As such, this court has the inherent authority to develop and adapt it to the circumstances at issue. State v. Lombardo Bros. Mason Contractors, Inc. , 307 Conn. 412 , 436, 54 A.3d 1005 (2012) (acknowledging that this court has "authority to adapt the common law to the changing needs of society," although not in sovereign immunity cases). 6 Accordingly, because the rule at issue is a common-law rule, this court has the authority to clarify, develop, and adapt the rule, including limiting its scope and applicability through exceptions.

As discussed, our cases have recognized an exception to the common-law rule that a trial court loses jurisdiction upon sentencing, and have done so in situations that are logical and sensible. See State v. Wilson , supra, 199 Conn. at 437 , 513 A.2d 620 ; see also State v. Myers , supra, 242 Conn. at 136 , 698 A.2d 823 . In my view, it requires no extension of our existing case law to hold that such an appropriate and sensible exception to the common-law rule applies in this case. I would not hold that we have overruled those cases sub silentio, or that we should overrule them explicitly now. Rather, the case that the majority holds governs the present situation, Luzietti , I find plainly distinguishable.

This court exercised its common-law authority in Wilson , holding that the four month rule applicable in civil cases applied equally in criminal cases. In doing so, we created an exception to the general common-law rule that courts lose jurisdiction upon sentencing. See State v. Wilson , supra, 199 Conn. at 437 , 513 A.2d 620 . Under this exception, the trial court in the present case had jurisdiction to rule on the timely filed motion for a new trial, despite the defendant's having begun serving his sentence, because the motion was filed and, even with an extension of time for briefing, was to have been ruled on within four months of the sentencing. 7 Clearly, if a court retains jurisdiction to modify a sentence for up until four months after the judgment, a timely motion for a new trial filed prior to sentencing falls within this four month time frame. Accordingly, under the four month rule espoused in Wilson , even after sentencing, the trial court retained jurisdiction to rule on the timely filed motion for a new trial because the motion's filing and the court's ruling both occurred before four months had passed after sentencing.

Then, in Myers , this court stated that "the trial court retained jurisdiction to entertain the motion for a new trial [that was timely filed prior to sentencing but not decided until] after sentencing because it could have opened the judgment." (Footnote omitted.) State v. Myers , supra, 242 Conn. at 136 , 698 A.2d 823 . In Myers , we cited to Wilson and acknowledged, in a footnote, that the four month rule applied equally in criminal and civil cases. See id., 136 n.16, 698 A.2d 823 . Thus, as a result of the timely filing of the motion prior to sentencing, the four month rule applied to the defendant's motion in Myers. The trial court, in Myers , however, did not rule on the motion for a new trial within four months of sentencing the defendant. This possibly suggests that Myers not only applied the four month rule, but determined that the trial court retains jurisdiction over a motion for a new trial as long as it was timely filed prior to sentencing, even if the court did not rule on the motion within the four month time frame. 8 To the extent that the court in Myers misapplied the four month rule in this regard, such an error does not affect the applicability of the four month rule to the present case, in which the trial court did rule on the motion within four months of sentencing. See footnote 7 of this concurring and dissenting opinion. In all other aspects, the procedural posture of the present case is nearly identical to that of Myers : a motion for a new trial filed before sentencing and within the time permitted to file such a motion. 9 Accordingly, pursuant to Myers , the trial court in the present case retained jurisdiction to decide the defendant's motion for a new trial.

The majority counters that the four month rule does not apply, in essence holding that Luzietti and subsequent cases overruled Wilson and Myers sub silentio. In State v. Luzietti , supra, 230 Conn. 427 , 646 A.2d 85 , which ignores the four month rule, the defendant timely filed his motion for a judgment of acquittal, and the trial court denied it prior to sentencing. Id., at 429, 646 A.2d 85 . Six weeks after sentencing, the defendant filed a motion for reargument. Id. The trial court granted reargument but denied relief, holding that it could not grant the underlying motion for a judgment of acquittal because it did not have jurisdiction to modify the judgment. Id., at 429-30, 646 A.2d 85 . In Luzietti , however, this court was not faced with determining whether the trial court retained jurisdiction to decide a timely filed motion for a new trial that was filed prior to sentencing, but rather was faced with a motion for reargument filed after sentencing regarding a motion for a judgment of acquittal that already had been denied prior to sentencing.

Similarly, all the other post- Myers cases that the majority relies on to reject the four month rule are distinguishable because they involve motions or petitions filed after sentencing. See State v. Ramos , supra, 306 Conn. at 128-29 , 49 A.3d 197 (motion to vacate filed more than three years after judgment); State v. Parker , supra, 295 Conn. at 830, 992 A.2d 1103 (motion to correct illegal sentence filed after sentencing); State v. Das , 291 Conn. 356 , 360, 968 A.2d 367 (2009) (motion to vacate judgment filed after sentencing); State v. Lawrence , 281 Conn. 147 , 151, 913 A.2d 428 (2007) (motion to correct illegal sentence filed after sentencing); State v. Reid , 277 Conn. 764 , 771, 894 A.2d 963 (2006) (motion to withdraw guilty plea filed after sentencing); Cobham v. Commissioner of Correction , 258 Conn. 30 , 35, 779 A.2d 80 (2001) (petition for writ of habeas corpus seeking to correct illegal sentence filed after sentencing). Thus, even if the majority is correct that Luzietti and its progeny overrule Wilson sub silentio, making the four month rule inapplicable in criminal cases in which a motion is filed after sentencing, Luzietti does not affect the holding of Myers , which permits a court to retain jurisdiction overly a timely filed motion for a new trial filed prior to sentencing. I see no reason why this court's decision in Luzietti would or should have any effect on our decision in Myers.

B

In the civil context, a circumstance such as the present one-the "unintentional" loss of jurisdiction over a timely filed motion-would very likely be called a "mutual mistake," authorizing the court to open its judgment to rule on the motion. See Kenworthy v. Kenworthy , 180 Conn. 129 , 131, 429 A.2d 837 (1980) ; Carabetta v. Carabetta , 133 Conn. App. 732 , 735, 38 A.3d 163 (2012). A mutual mistake is a mistake "that is common to both parties and effects a result that neither intended." (Internal quotation marks omitted.) Terry v. Terry , 102 Conn. App. 215 , 229, 925 A.2d 375 , cert. denied, 284 Conn. 911 , 931 A.2d 934 (2007). In the present case, as the Appellate Court accurately described it, the parties and the trial court made the "collective mistake" of believing that the court would retain jurisdiction over the new trial motion once the defendant had been sentenced. State v. McCoy , supra, 171 Conn. App. at 328 n.6, 157 A.3d 97 . In my view, even if the majority is correct that Luzietti has thrown cold water on Wilson and Myers , the trial court could have opened the judgment to rule on the new trial motion under the related concept of mutual mistake.

In civil cases, General Statutes § 52-212a permits parties to file a motion to open or set aside the judgment within four months from the date of judgment. There is an exception, however, for cases in which the judgment was based on fraud or mutual mistake: "It is a well-established general rule that even a judgment rendered by the court ... can subsequently be opened [after the four month limitation] ... if it is shown that ... the judgment, was obtained by fraud ... or because of mutual mistake." (Internal quotation marks omitted.) In re Jonathan M. , 255 Conn. 208 , 238, 764 A.2d 739 (2001). This authority stems from the courts' "intrinsic powers, independent of statutory provisions authorizing the opening of judgments, to vacate any judgment obtained by fraud, duress or mutual mistake." In re Baby Girl B. , 224 Conn. 263 , 283, 618 A.2d 1 (1992) ; see also In re Samantha S. , 120 Conn. App. 755 , 758 n.3, 994 A.2d 259 (2010) ("[a] common-law motion to open must be predicated on fraud, duress or mutual mistake"), appeal dismissed, 300 Conn. 586 , 15 A.3d 1062 (2011).

"Mutual mistake is an equitable principle that allows for the court to work fairness, equity and justice." (Internal quotation marks omitted.) In re Santiago G. , 154 Conn. App. 835 , 841 n.6, 108 A.3d 1184 , aff'd, 318 Conn. 449 , 121 A.3d 708 (2015). Fairness, equity and justice are essential to the justice system as a whole, not just to the civil side of that system. Although this court never has applied the mutual mistake exception in a criminal case, I can think of no policy reason that justifies remedying mutual mistakes in civil cases but not in criminal cases, especially in light of the greater liberty interests at stake in criminal cases. The Appellate Court, in fact, has noted that the exception should apply equally in criminal cases. In State v. Dayton , supra, 176 Conn. App. at 871 n.13, 171 A.3d 482 , that court explained that in civil cases, there is an exception to the four month rule if the judgment was obtained by fraud or mutual mistake. Citing to Wilson , the Appellate Court acknowledged that there was no reason for either the four month rule or the mutual mistake exception not to apply equally to criminal cases. Id. 10

This court can, and in my view should, exercise its inherent authority to develop and adapt the common-law rule at issue by extending the mutual mistake exception to criminal cases. See part I A of this concurring and dissenting opinion. In exceptional circumstances, as in the present case, where both parties and the court did not realize that application of the rule at issue would deprive the court of jurisdiction, such a mutual mistake should not divest the court of jurisdiction to decide a timely filed motion for a new trial. See State v. Brown , 8 Conn. App. 248 , 251, 512 A.2d 965 (1986) (" '[W]hen a court has acquired jurisdiction, no subsequent error or irregularity will oust the jurisdiction thus acquired. It does not lose jurisdiction because it makes a mistake in determining either the facts or the law, or both, in the case before it,' " quoting 22 C.J.S. 423-24, Criminal Law § 165 [1961].). Such an application of the rule is unfair, inequitable and unjust, and I would therefore conclude that the court could have exercised jurisdiction to rule on the motion for a new trial in this case because of mutual mistake.

C

Even if, as the majority suggests, neither of these exceptions apply and our current case law does not permit a trial court after sentencing to rule on a timely filed motion for a new trial, I believe we can and should recognize such a sensible exception to what Holmes would refer to as the "axioms and corollaries [akin to] a book of mathematics." O. Holmes, supra, p. 5. As discussed previously, the rule at issue is a common-law rule. As a common-law rule borne out of experience and sensibility; see id.; this court has the inherent power to define its contours to ensure that its application does not lead to unsensible and unjust results, inherent power that includes the ability to limit its scope and applicability through exceptions to it, such as for timely filed motions for a new trial.

Ultimately, it is a question of judicial policy for this court to determine whether our common-law rule should prevent a timely filed motion for a new trial from being adjudicated when the trial court and the parties mistakenly believed that the court could rule on the motion after sentencing. See Dacey v. Connecticut Bar Assn. , 184 Conn. 21 , 25-26, 441 A.2d 49 (1981) (defining common law as "the prevailing sense of the more enlightened members of a particular community, expressed through the instrumentality of the courts ... in view of the particular circumstances of the time" [internal quotation marks omitted] ). I would hold that our law should permit a trial court under these circumstances to exercise jurisdiction to rule on the timely filed motion for a new trial. If the trial court denies the motion, the court's judgment and sentence remain the same. If the trial court were to find the motion to have merit, I believe our law should permit the court to "open, correct and modify" its judgment by vacating the sentence and ordering a new trial, just as our court could order if, on appeal, we were to find error. Such an exception would be consistent with this court's holding in Myers , to the extent that Myers does not rely on the four month rule. It may be unclear from Myers whether the court relied solely on the four month rule in holding that the trial court retained jurisdiction over a motion for a new trial that was timely filed prior to sentencing, but not ruled on until after sentencing. See State v. Myers , supra, 242 Conn. at 136 , 698 A.2d 823 . What is clear from Myers , however, is that this court held that there was an exception to the common-law rule at issue under such circumstances. Just as in Myers , the trial court in the present case originally had jurisdiction over a timely filed motion for a new trial, and the issue is whether the court then accidentally lost jurisdiction. As a matter of law, Myers clarified that the common-law rule does not deprive the court of jurisdiction in these circumstances. As a matter of judicial policy, such an exception is necessary to protect a defendant's ability to seek review of his new trial claims from the court that presided over the trial and had the opportunity to view the effect of any alleged improprieties.

The state argues that an unflinching application of the general rule is necessary to ensure eventual finality and to prevent trial judges from dawdling over motions for too long. Both policies are laudable, but, in my view, neither suffices to justify strict adherence to a supposed general rule at such a cost to defendants. 11

First, as the state admitted candidly in argument before this court, finality is not achieved in this case: it is an illusion. Namely, the issues raised in the timely motion that the trial court accidentally lost jurisdiction over can and will be raised in postjudgment petitions for a new trial or habeas corpus or a motion to correct an illegal sentence. See State v. Parker , supra, 295 Conn. at 837, 839, 992 A.2d 1103 ("permitting correction of both illegal sentences and sentences imposed in an illegal manner" and noting that "[t]he defendant has a legitimate interest in the character of the procedure which leads to the imposition of sentence even if he may have no right to object to a particular result of the sentencing process" [internal quotation marks omitted] ). The state goes on to argue that while that might be true, there is virtue in moving the case along to the inevitable next step.

Although I cannot disagree with-and perhaps join the state in-the cynical view on which this argument is based (i.e., there will always be a postjudgment challenge), to me, this inevitability should not contribute to the misapplication of a rule to a situation to which it should not apply. Moreover, although this defendant or any other might very well be able to add his new trial claims to any other collateral challenge he brings, as the state well knows, the obstacles to relief for a convicted criminal defendant increase as the burdens of proof heighten in collateral proceedings. 12 Would it not have been better for everyone if we had the considered views of the trial judge on these issues (issues the trial judge called "colorable"), whether on direct appeal or on collateral review? In fact, we must defer to the judge who sat through the trial and witnessed the impact on the jury of the prosecutor's actions and the court's rulings. See State v. Smith , 313 Conn. 325 , 347, 96 A.3d 1238 (2014) ("the trial [judge has a] superior opportunity to assess the proceedings over which he or she has personally presided" [internal quotation marks omitted] ). Ruling on the issue through a timely filed motion for a new trial, reviewed on direct appeal with deference, very likely removes the issue from among any the defendant might seek to raise in a collateral proceeding.

Additionally, this court previously has rejected arguments that the need for "finality" justifies upholding a judgment obtained through mutual mistake or fraud. In In re Baby Girl B. , supra, 224 Conn. at 265-66 , 618 A.2d 1 , the commissioner of the Department of Children and Youth Services (commissioner) filed a petition for termination of parental rights on the ground of abandonment pursuant to General Statutes (Rev. to 1991) § 17a-112 (b) (1). Four months after the petition was granted, the respondent mother moved to open the judgment pursuant to § 52-212a. Id., at 266, 618 A.2d 1 . The trial court granted the motion to open and denied the petition for termination of parental rights. Id., at 266-67, 618 A.2d 1 . On appeal, the commissioner argued that the trial court improperly granted the motion to open because § 52-212a did not apply to petitions for termination of parental rights and because there was a public policy in favor of finality in cases involving juveniles. Id., at 281-82, 618 A.2d 1 .

This court in In re Baby Girl B. rejected the commissioner's position, not only because it was in conflict with the plain language of § 52-212a ; id., at 282, 618 A.2d 1 ; but also because the commissioner's argument for finality conflicted with the court's statutory and "intrinsic powers" to open judgments. Id., at 283, 618 A.2d 1 . Although the court in In re Baby Girl B. , was required to interpret § 52-212a, the court's analysis established that a public policy in favor of finality does not necessarily trump the court's inherent authority to open judgments.

Finally, even as the majority applies the jurisdictional rule with exactitude, it tempers the rule with an obvious work-around: the trial court can simply sentence the defendant and stay the sentence until the court gets around to ruling on the motion. See State v. Walzer , 208 Conn. 420 , 424-25, 545 A.2d 559 (1988). In my view this is no rule at all. Although I agree with the majority that staying the proceedings is a "useful mechanism," 13 it surely does not vindicate the policies the state offers in support of the rule. This work-around undercuts not only the finality of the judgment, but also the other policy justification the state offers for the draconian rule the majority adheres to, i.e., that trial judges will take too long to rule on such motions. I am not aware that this is a prevalent problem. If it is, perhaps it is an issue the Rules Committee of the Superior Court can address. But the sanction of the court losing jurisdiction over a timely motion for a new trial that it characterized as "colorable" seems to me to be a solution far out of proportion to a potential problem that is so easily overcome by other means. Better in my view to recognize an exception to the rule than to pay lip service to a rule so easily avoided, especially when an exception would be an equally useful mechanism. 14

As a result, I find neither of the state's policy justifications persuasive. Rather, on the basis of judicial experience and sensibility; see O. Holmes, supra, p. 5; I believe judicial policy, consistent with this court's holding in Myers , favors recognizing an exception under the circumstances at issue in this case. As a result of either accident or the parties' mutual oversight of controlling law, a defendant should not be deprived of his opportunity to have his properly filed common-law motion for a new trial decided by the judge who oversaw his criminal trial, and personally observed the jury and its reaction to evidence and arguments.

II

Even if I were to accept the majority's conclusion that there is no exception under the common law that would permit the trial court to rule on a timely filed motion for a new trial after the defendant had been sentenced, I have no trouble calling the trial court's "unintentional" loss of jurisdiction what it clearly was: plain error. As two erudite commentators have advised: "Plain error is most likely found where the trial court and the parties have overlooked clearly controlling law, be it a constitution, statute, rule, case law or 'established practice.' " C. Tait & E. Prescott, Connecticut Appellate Practice and Procedure (3d Ed. 2000) § 8.7, p. 304. This seems to me to be a textbook-perhaps hornbook-example of plain error: the trial court and the parties overlooked controlling case law when the court, with the parties' agreement, continued the new trial motion and went on to sentence the defendant. More specifically, if both the state and the Appellate Court are correct that the "traditional rule" applies in the present case, ending the trial court's jurisdiction when the sentence was pronounced and executed, with no exception for a timely filed motion for a new trial or the parties' and the court's mutual mistake, in my view it was plain error for the trial court to so pronounce and execute sentence, leaving a properly filed motion to be lost in the oblivion. At the very least, the court should have stayed the defendant's sentence while it considered the motion, as the majority suggests trial courts do routinely.

I fully recognize that "[t]he plain error doctrine is reserved for truly extraordinary situations [in which] the existence of the error is so obvious that it affects the fairness and integrity of and public confidence in the judicial proceedings .... [I]n addition to examining the patent nature of the error, the reviewing court must examine that error for the grievousness of its consequences in order to determine whether reversal under the plain error doctrine is appropriate. A party cannot prevail under plain error unless it has demonstrated that the failure to grant relief will result in manifest injustice .... [Previously], we described the two-pronged nature of the plain error doctrine: [An appellant] cannot prevail under [the plain error doctrine] ... unless he demonstrates that the claimed error is both so clear and so harmful that a failure to reverse the judgment would result in manifest injustice." (Citations omitted; emphasis in original; internal quotation marks omitted.) State v. McClain , 324 Conn. 802 , 812-13, 155 A.3d 209 (2017).

In my view, the trial court's failure to rule on a timely filed motion for a new trial-perhaps in any case, but surely in a case in which the court has effectively pronounced a life sentence on the defendant-clearly "affects the fairness and integrity of and public confidence in the judicial proceedings." 15 (Internal quotation marks omitted.) Id., at 812 , 155 A.3d 209 . Judges have an obligation to rule on motions, certainly timely filed motions that raise "colorable" issues. See Amato v. Erskine , 100 Conn. 497 , 499, 123 A. 836 (1924) ("[it is the court's] right and duty to determine every question which may arise in the cause" [internal quotation marks omitted] ); Code of Judicial Conduct, Rule 2.7 ("[a] judge shall hear and decide matters assigned to the judge"). The trial court in this case failed in that obligation by losing jurisdiction over the motion. That it did so accidentally or inadvertently does not make it any more fair to the defendant or impact public confidence any less. I do not read the majority to contend otherwise. Rather, while acknowledging that it was error for the trial court not to rule on the pending motion, the majority concludes that this error was neither so obvious nor so harmful as to constitute "manifest injustice." I do not agree. As to whether the error was "so clear" or "so obvious," the majority appears to conclude that the error falls in a sweet spot (or, for the defendant, a not so sweet spot). Namely, we are told that the rule that the trial court loses jurisdiction upon sentencing is a "generally accepted" and "well established" jurisdictional and common-law doctrine. Yet, because of what the majority considers to have been "anomalies in this court's case law" that "may have resulted in some confusion," the error was not sufficiently clear to fall within the clear error test. This is a needle I have a hard time threading. The majority's view might be persuasive if, when the trial court sentenced the defendant without ruling on his timely new trial motion, it had sorted among what the majority finds to be anomalous or confusing precedents. But, like the parties, the trial court missed altogether the "loss of jurisdiction" issue, sorting among the precedents only after the horse had left the jurisdictional barn. Thus, the trial court's error was not in determining whether Luzietti applied, as opposed to Wilson and Myers , but rather in not considering the import of the "well established" rule at all , at a time when it still could have ruled on the defendant's motion, as it was obliged to, including by putting off the sentencing proceeding or by pronouncing sentence and staying its execution. Whether this error actually affected the court's subject matter jurisdiction was perhaps arguably not clear or obvious, but the fact that the court should have, but did not, rule on the new trial motion prior to sentencing was clear and obvious. By not doing so, the defendant was denied an opportunity to seek a new trial pursuant to Practice Book § 42-53. This seems to me exactly the kind of error that the plain error doctrine was designed to address.

As to the second prong of the plain error test, although I agree with the majority that unlike the situation for defendants in structural error cases, the defendant in the present case was required to establish harm that amounts to manifest injustice, I disagree that the defendant failed to do so. The majority concludes that there is no "manifest injustice" because the alleged prosecutorial improprieties detailed in the motion for a new trial are the same improprieties that this court concludes lack merit on direct appeal. What the record in this appeal lacks, however, is the ruling of the trial judge who presided over the defendant's trial. Today's majority essentially declares that that ruling was unnecessary. I do not agree, and I would conclude that the defendant was harmed by not having his motion for a new trial reviewed first by the trial judge who supervised his criminal trial, notwithstanding our conclusion today affirming the judgment of the trial court on the record presented. See footnote 1 of this concurring and dissenting opinion.

It is well established that a trial judge is in a better position to assess any error or prejudice that occurred during trial. It is the trial judge who viewed the evidence, heard the witnesses' testimony and counsel's arguments, and viewed the jury's reaction. Motions for a new trial provide the best remedy when claims of prosecutorial impropriety are alleged because they permit the trial court to rely on its personal experience at trial, during which the court may have observed the effect and prejudice, if any, the impropriety had on the jury. It is because of this firsthand experience that trial courts are afforded discretion in deciding motions for a new trial, which we then review for abuse of that discretion. See State v. Myers , 290 Conn. 278 , 288-89, 963 A.2d 11 (2009). Thus, the manifest injustice in this case is not necessarily that the defendant would have prevailed on his claims, but rather that the parties and this court have lost the benefit of the trial court's considered views of his claims, especially in light of the fact that the trial judge deemed the defendant's motion for a new trial "colorable ...." Even if the trial court would have denied the motion, we would have had the benefit of a record of its reasons for doing so, which potentially could impact our review of the claims on direct appeal.

It is the significance of the trial court's discretion that distinguishes this case from the case cited by the majority, State v. Myers , supra, 290 Conn. 278 , 963 A.2d 11 . In Myers , defense counsel waived a trial on part B of the information, which charged the defendant as a repeat offender, and, thus, the trial court did not "accord him a hearing regarding his jeopardy as a repeat offender and ... make a finding regarding his status as a repeat offender in accordance with Practice Book § 42-2...." (Internal quotation marks omitted.) Id., at 285, 963 A.2d 11 . The Appellate Court in Myers had held that the trial court's failure to abide by § 42-2 was plain error because "[a] court commits plain error when it fails to implement properly the mandatory provisions of clearly applicable rules of practice." (Internal quotation marks omitted.) Id. This court reversed in part the judgment of the Appellate Court, explaining that "apart from the trial court's failure to comply strictly with the applicable rule of practice, which we do not condone, the defendant has failed to raise any doubt with respect to the validity of his prior conviction. A trial court's failure to comply with a rule of criminal procedure, without more, is insufficient to require reversal for plain error." (Emphasis omitted; footnote omitted.) Id., at 290, 963 A.2d 11 .

The present case is distinguishable from Myers because the defendant in Myers did not request that the trial court exercise its discretion. The sole issue in Myers was the legal question of whether the defendant could waive a hearing on the part B information and bypass Practice Book § 42-2. In the present case, the trial court was required to exercise its discretion to determine whether to grant a new trial on the basis of whether the alleged prosecutorial improprieties prejudiced the defendant.

At great risk of being unduly practical, and understanding that the defendant must demonstrate prejudice, I fail to understand just what the state and the majority fear here. If the trial court denies the defendant's motion, the court has vindicated the defendant's right to a ruling on his timely motion, respected its authority and obligation to rule on that motion, and prevented collateral litigation on the failure of the court to rule on the motion and the failure of the parties to recognize their oversight. If the trial court grants the motion for a new trial, there is no need for this appeal, unless the state seeks and obtains permission to appeal. See General Statutes § 54-96 (state cannot appeal in criminal case unless permitted to do so by trial court).

I further part company with the majority on the issue of manifest injustice in that the majority already has concluded that the trial court could not under any circumstances have granted the motion as a matter of discretion. I reject that notion. It was the trial judge who observed the questions the prosecutor posed, the witnesses' conduct and the jury's reaction, and expressed his own frustration with the prosecutor. See State v. McCoy , supra, 171 Conn. App. at 316 , 157 A.3d 97 . I do not agree that our affirmance of the judgment on the prosecutorial impropriety issues raised; see part I of the majority opinion; means that the trial court's own ruling on those issues was preordained or ineluctable. It is not possible to say that the court would have abused its discretion if the record had been augmented by the court's views and the court had granted the motion for a new trial on the basis of the issues the defendant sought to raise in that motion. And if the trial court had granted the motion, there could be no doubt that the defendant had been so harmed as to amount to manifest injustice.

Nor can I agree with the state that the defendant has suffered no manifest injustice because he can always raise his claims in a petition for a new trial or for a writ of habeas corpus. As the state well knows, the burdens of demonstrating prejudice are much steeper in such collateral proceedings. See footnote 12 of this concurring and dissenting opinion. In addition, the defendant would suffer prejudice by virtue of any delay he would endure if he were entitled to prevail, and would have prevailed, on his timely filed motion. In fact, being consigned to having to raise his claims in a collateral proceeding because of the trial court's accidental and inadvertent loss of jurisdiction is the manifestation of prejudice that in my view warrants invoking the plain error doctrine. Accordingly, because the error in this case was clear and harmful, I would reverse the judgment of the Appellate Court and remand the case to that court with direction to remand the case to the trial court to rule on the motion for a new trial. 16

I therefore respectfully concur in part and dissent in part.
