*3 Opinion

The issue in this interlocutory1 appeal2 is whether the trial court abused its discretion in declaring a mistrial, over the defendants’ objection, on the ground of manifest necessity after the senior assistant state’s attorney had become seriously ill and was unable to continue with the trial. We conclude that the trial court did not abuse its discretion.

The record reveals the following relevant facts and procedural history. In connection with the alleged embezzlement of tens of thousands of dollars, the defendants, Richard Anderson and Janice Anderson, each were charged with, in separate informations, two counts of larceny in the first degree in violation of General Statutes § 53a-122 (a) (2),3 and one count of conspiracy to commit larceny in the first degree in violation of § 53a-122 (a) (2) and General Statutes § 53a-48 (a). The two informations were consolidated for trial. On May 2, 2007, jury selection commenced and continued for approximately fifteen days. Six jurors and four alternate jurors ultimately were selected. During voir dire of the potential jurors, the court, Schimelman, J.,4 informed the jurors that the trial was expected to start on June 12, 2007, and to last approximately five and one-half weeks.

*4On June 12, 2007, the jury was sworn, and the state began its case-in-chief. The trial continued until Friday, June 22,2007. During that time, eight witnesses testified and nearly 400 exhibits were introduced. On June 24, 2007, the trial court was informed that the senior assistant state’s attorney prosecuting the case, John H. Malone, had become seriously ill and had to be hospitalized. The court delayed the trial until July 5, 2007, in the hope that Malone would be able to return.

On July 5, 2007, the court held a hearing for the purpose of discussing potential dates to resume the trial. At the hearing, the state was represented by John R. Whalen, a supervisory assistant state’s attorney, due to the continued illness of Malone. Initially, the court believed, on the basis of the information it had received to that date about Malone’s health, that the earliest date on which the trial could resume was August 6, 2007. The court intended to discuss this potential date with the jurors, even though some of the jurors already had expressed scheduling concerns before Malone was hospitalized. Just minutes before coming out to the courtroom, however, the court, with the agreement of defense counsel, spoke with Malone on the telephone and learned that his condition was going to necessitate further hospitalization and a period of convalescence that was longer than the parties and the court originally had anticipated. On the basis of this new information, the court concluded that the resumption of the trial on August 6,2007, would not be possible. The court further concluded that it would not be feasible to talk to the jurors about the possibility of resmning the trial in September, 2007, because of the seriousness of Malone’s illness and the uncertainty regarding when he might be able to return to complete the trial.

The trial court also noted that, during its discussion with counsel in chambers, Whalen had represented that it was the state’s view that another prosecutor would *5not be able to replace Malone because of the complexity of this case. The court agreed, on the basis of its own observations, that the case was “very complex,” and noted that the state already had offered more than 300 exhibits into evidence but had not yet reached “the heart of the case . . . .” The court further observed that the forensic accountants had yet to testify and that their testimony was expected to be lengthy. The court informed the parties that it did not believe that it was feasible to continue with the trial and, therefore, that it intended to declare a mistrial on the ground of manifest necessity.

Prior to declaring a mistrial, the court afforded counsel the opportunity to be heard on the record. Whalen stated that he did not think another prosecutor “could step in at this point and try to salvage this case until [Malone] returns, or finish it if he doesn’t return.” Whalen further stated that “we have all been caught by surprise. This is certainly one of those incidents where there is manifest necessity, and . . . the court is well within the law in declaring a mistrial.” Defense counsel objected to a mistrial and stated that “the defendants have a valid constitutional right to have the case decided by a jury of their choice,” and that it was his “feeling that this jury was attentive to this case and that [the defense] had made significant points in establishing reasonable doubt ... if not complete innocence with respect to [the defendants].” Defense counsel further argued that “the state . . . should have been prepared,” and, in view of the projected length and complexity of the trial, “it would have been wise [for] the state [to have obtained] a second lawyer in a case like this [one].”

After hearing the parties’ arguments, the court summoned the jurors and declared a mistrial on the ground of manifest necessity. Specifically, the trial court found manifest necessity on the basis of “the totality of the *6circumstances,” including (1) “the medical condition of . . . Malone,” (2) “the lack of the ability to ask another [prosecutor] to step in because the preparation time . . . would be significant,” and (3) “the fact that [there are] jurors who [were] already chomping at the bit, so to speak, because of the time constraints that [the court] had originally estimated and because of the fact that these jurors [had] things that they had planned to do.”

The defendants thereafter filed a joint motion to dismiss the charges against them, claiming that the trial court’s declaration of a mistrial, over their objection, had not been based on manifest necessity and, therefore, that further prosecution would violate the guarantee against double jeopardy. The trial court, Handy, J., denied the defendants’ motion to dismiss and concluded that “the mistrial was properly declared by the court . . . over the defendants’ objection, based on manifest necessity, after [the court] considered all possible alternatives and after [it] weighed the totality of the circumstances.” This appeal followed.

On appeal, the defendants claim that the trial court’s finding of manifest necessity was improper because the court failed to explore the alternative of a “reasonable, even if somewhat lengthy, continuance in order to allow another [prosecutor] to assume responsibility for the case.” Specifically, the defendants claim that the trial court’s reliance on Whalen’s representations that, due to the complexity of the case, another prosecutor would not be able to replace Malone, was, “without more . . . insufficient to outweigh [the] defendants’ valued right to have the original jury decide the case.” In addition, the defendants claim that the trial court improperly failed to poll the jurors on their “availability in September [of 2007], or beyond.” (Emphasis in original.)

The state responds that the trial court was entitled to credit Whalen’s representations regarding the *7unavailability of a substitute prosecutor and that the defendants never disputed or challenged such representations or the court’s finding that the case was “very complex . . . .” Accordingly, the state argues that the trial court was not required to poll the jurors as to their availability before declaring a mistrial because such an act would have been futile, as there was no future date certain when the trial could resume. The state therefore argues that, on the basis of the totality of the circumstances, the trial court properly exercised its discretion in declaring a mistrial on the ground of manifest necessity. We agree with the state and, therefore, conclude that the court, Handy, J., properly denied the defendants’ motion to dismiss.

We begin with a review of the doctrine of double jeopardy under the federal and state constitutions. The fifth amendment to the United States constitution provides in relevant part: “No person shall ... be subject for the same offense to be twice put in jeopardy of life or limb . . . .” This clause is applicable to the states through the due process clause of the fourteenth amendment; Benton v. Maryland, 395 U.S. 784, 794, 89 S. Ct. 2056, 23 L. Ed. 2d 707 (1969); and establishes the federal constitutional standard concerning the guarantee against double jeopardy. Although the Connecticut constitution does not include a specific double jeopardy provision,5 we have held that “the due process and personal liberty guarantees provided by article first, *8§§ 86 and 9,7 of the Connecticut constitution . . . encompass the protection against double jeopardy.” (Internal quotation marks omitted.) State v. Kasprzyk, 255 Conn. 186, 192, 763 A.2d 655 (2001). The protection afforded against double jeopardy under the Connecticut constitution “mirrors, rather than exceeds,” that which is provided by the constitution of the United States. (Internal quotation marks omitted.) State v. Michael J., 274 Conn. 321, 350, 875 A.2d 510 (2005). In atrial by jury, “[j]eopardy attaches once the jury has been selected and sworn. . . . Illinois v. Somerville, 410 U.S. 458, 467, 93 S. Ct. 1066, 35 L. Ed. 2d 425 (1973).” (Citation omitted.) State v. Buell, 221 Conn. 407, 413, 605 A.2d 539, cert. denied, 506 U.S. 904, 113 S. Ct. 297, 121 L. Ed. 2d 221 (1992).

The constitutional protection against double jeopardy includes the defendant’s “valued right to have his trial completed by a particular tribunal.”8 (Internal quotation marks omitted.) Arizona v. Washington, 434 U.S. 497, 503, 98 S. Ct. 824, 54 L. Ed. 2d 717 (1978). “This right is not absolute, however, and may in some cases be subordinated to the public interest in affording the prosecutor one full and fair opportunity to present his *9evidence to an impartial jury. [Id.], 505.” (Internal quotation marks omitted.) State v. Buell, supra, 221 Conn. 413-14. Therefore, “[w]henacriminaldefendantobjects to the declaration of a mistrial . . . and the mistrial is declared for reasons amounting to ‘manifest necessity,’ his right to have his trial completed by his chosen tribunal is no longer protected and the double jeopardy clause does not bar a second trial.” State v. Van Sant, 198 Conn. 369, 377, 503 A.2d 557 (1986).

“The primary definition for when ‘manifest necessity’ justifies declaring a mistrial was articulated by the United States Supreme Court in United States v. Perez, 22 U.S. (9 Wheat.) 579, 580, 6 L. Ed. 165 (1824) State v. Kasprzyk, supra, 255 Conn. 193. Justice Joseph Story, writing for the court in Perez, stated: “[I]n all cases of this nature, the law has invested [c]ourts of justice with the authority to discharge a jury from giving any verdict, whenever, in their opinion, taking all the circumstances into consideration, there is a manifest necessity for the act, or the ends of public justice would otherwise be defeated. They are to exercise a sound discretion on the subject; and it is impossible to define all the circumstances . . . which would render it proper to interfere. To be sure, the power ought to be used with the greatest caution, under urgent circumstances, and for very plain and obvious causes .... [T]he faithful, sound, and conscientious exercise of this discretion . . . rests . . . upon the responsibility of the [j]udges, under their oaths of office.” United States v. Perez, supra, 580.

Our standard of review for whether a mistrial was justified by manifest necessity is well settled. “Because of the importance of the defendant’s right to have his trial concluded by a particular tribunal, ‘the prosecutor must shoulder the burden of justifying the mistrial if he is to avoid the double jeopardy bar. His burden is a heavy one. The prosecutor must demonstrate “manifest *10necessity” for any mistrial declared over the objection of the defendant.’ . . . With respect to construction of the terms ‘manifest necessity,’ a ‘high degree’ of ‘necessity’ is required before a conclusion may be reached that a mistrial is appropriate . . . .” (Citation omitted.) State v. Van Sant, supra, 198 Conn. 378-79, quoting Arizona v. Washington, supra, 434 U.S. 505-506. The United States Supreme Court has rejected “the application of any mechanical formula by which to judge the propriety of declaring a mistrial in the varying and often unique situations arising during the course of a criminal trial.” Illinois v. Somerville, supra, 410 U.S. 462; see also United States v. Jorn, 400 U.S. 470, 480, 91 S. Ct. 547, 27 L. Ed. 2d 543 (1971). We, too, have eschewed a mechanical application of the manifest necessity standard “because the ‘high degree’ of necessity mandated by that phrase can be found in a variety of circumstances.” State v. Van Sant, supra, 379; see also State v. Buell, supra, 221 Conn. 414. Nevertheless, in analyzing this issue in prior cases, we have considered the following nonexclusive list of factors: (1) the timing of the events leading to the declaration of a mistrial; (2) whether the court and parties were taken by surprise; and (3) whether the court considered available alternatives to a mistrial. See State v. Kasprzyk, supra, 255 Conn. 203. In addition, we have stated that “a trial court’s determination will not be upheld if the trial court reasonably could have avoided a mistrial, or if the court acted in an erratic or precipitous manner.” Id., 203-204.

On appellate review, “ ‘the trial judge’s decision whether manifest necessity exists to declare a mistrial should be afforded the “highest degree of respect.” ’ ” United States v. Millan, 17 F.3d 14, 19-20 (2d Cir. 1993); see also State v. Daniels, 207 Conn. 374, 394-95 n.12, 542 A.2d 306 (1988) (“the trial corut’s assessment of the necessity for a mistrial is accorded great deference”). The United States Supreme Court “has long *11favored the rule of discretion in the trial judge to declare a mistrial and to require another panel to try the defendant if the ends of justice will be best served . . . and . . . [has] consistently declined to scrutinize with sharp surveillance the exercise of that discretion.” (Citation omitted; internal quotation marks omitted.) Gori v. United States, 367 U.S. 364, 368, 81 S. Ct. 1523, 6 L. Ed. 2d 901 (1961). Accordingly, we will not disturb the trial court’s determination that there was manifest necessity in the absence of an abuse of discretion.9 United States *12v. Millan, supra, 20; see also Illinois v. Somerville, supra, 410 U.S. 468 (concluding that trial court’s declaration of mistrial on ground of manifest necessity was not abuse of discretion); United States v. Jorn, supra, 400 U.S. 486-87 (applying abuse of discretion standard to trial court’s decision to declare mistrial on ground of manifest necessity); State v. Buell, supra, 221 Conn. 420-21 (Borden, J., concurring) (concluding that trial court abused its discretion in declaring mistrial on ground of manifest necessity); cf. State v. Lucci, 25 Conn. App. 334, 342, 595 A.2d 361 (applying abuse of discretion standard to trial court’s failure to order “a mistrial on its own motion”), cert. denied, 220 Conn. 913, 597 A.2d 336 (1991). In determining whether a trial court abused its discretion, “[a] reviewing court looks for a manifest necessity by examining the entire record in the case without limiting itself to the actual findings of the trial court. ... It is the examination of the propriety of the trial court’s action against the backdrop of the record that leads to the determination [of] whether, in the context of a particular case, the mistrial declaration was proper.” (Citations omitted; internal quotation marks omitted.) State v. Van Sant, supra, 198 Conn. 379.

Applying this standard of review to the present case, we conclude that the trial court did not abuse its discretion in declaring a mistrial on the ground of manifest necessity. The trial court reasonably concluded that manifest necessity existed on the basis of the totality of the circumstances because (1) Malone unexpectedly became ill during the trial, (2) no other prosecutor would have been able to assume the prosecution within a reasonable time in light of the complexity of the case, and (3) there were jurors who were already “chomping *13at the bit” because of the time constraints that the court originally had estimated and because the jurors had prior plans that they wished to keep.

Our conclusion is consistent with our decision in State v. Van Sant, supra, 198 Conn. 369. In Van Sant, we held that the trial court in that case properly exercised its discretion in declaring a mistrial, over the defendant’s objection, on the ground of manifest necessity when a key state’s witness became ill while testifying. Id., 370, 384. The witness, a police detective, suffered a seizure on the stand while being cross-examined by defense counsel and was removed from the courthouse on a stretcher by medical personnel. Id., 370-71, 380 and n.8. In concluding that the trial court properly exercised its discretion in declaring a mistrial, we relied on five factors. See generally id., 380-82.

First, a key witness became seriously ill during trial, and his condition prevented him from testifying for an indefinite period. See id., 380. With regard to the witness’ medical condition, we noted the significant circumstance that the trial judge personally saw the witness as “he keeled over the stand . . . .” (Internal quotation marks omitted.) Id. The judge stated that it was “obvious that there was something drastically wrong with [the witness]” and that he “was convinced that there was no malingering going on.”10 (Internal quotation marks omitted.) Id. In addition, the court found that ordering the witness to testify “could detrimentally affect his health.” (Internal quotation marks omitted.) Id., 374. This finding was based on a letter from the witness’ cardiologist and the testimony of the witness’ *14family physician, both of whom indicated that, on the basis of the results of a cardiac stress test; id., 371-73; the witness should not be exposed to the “ ‘stressful procedure’ of the court proceedings . . . .” Id., 382.

Second, “the trial court proceeded deliberately and not precipitously” in exercising its discretion and declaring the mistrial. Id., 381. Specifically, the trial court delayed declaring the mistrial for about three weeks after the witness’ seizure. See id. Third, “the trial court properly . . . gave counsel the opportunity to be heard extensively on the matter.” Id. Fourth, the court considered the double jeopardy implications of its ruling by carefully weighing “the defendant’s right to have his trial completed,” on the one hand, and “the public’s interest in a fair trial and just judgment,” on the other. Id., 382. Finally, the trial court “realistically considered the alternatives to a mistrial . . . .” Id., 381. The court reasonably concluded that a continuance was not a viable option because “[t]here was no fair basis [on] which to estimate when [the witness] could testify.” Id., 382. In addition, the court determined that striking the testimony of the witness would not “resolve the problem”; id.; because the witness’ testimony constituted “critical prosecution evidence . . . .” (Internal quotation marks omitted.) Id., 380.

On the basis of our decision in Van Sant, we conclude that the trial court in the present case did not abuse its discretion in declaring a mistrial. First, as with the state’s witness in Van Sant, Malone became seriously ill during the trial, and his condition necessitated hospitalization, followed by a lengthy and indefinite period of convalescence. In addition, just as the trial judge in Van Sant personally observed the condition of the witness on the stand, the trial judge in the present case personally spoke with Malone on the telephone regarding the severity of his illness and concluded that it was evident that he “certainly . . . did not sound *15good” and that “he [was] not going to be able to come back to this matter for a significant period of time.”

Second, as with the trial court in Van Sant, the trial court in the present case “proceeded deliberately and not precipitously . . . .” State v. Van Sant, supra, 198 Conn. 381. The court did not rush to declare a mistrial after first learning of Malone’s illness on June 24, 2007, but, rather, waited eleven days, until July 5, 2007, and until after he learned more about Malone’s condition and the unavailability of a substitute prosecutor before taking such action. Third, prior to declaring the mistrial, the court properly gave counsel the opportunity to be heard. Fourth, the court considered the implications of its ruling and weighed the necessity of a mistrial against the defendants’ right to have their trial completed. Specifically, the court stated: “I understand the necessity and the fact that, obviously, the [defendants] have much invested in [the] matter as well; and I certainly have taken that into consideration. But . . . [i]n the court’s mind, it is not feasible that we continue this trial.”

Finally, as with the trial court in Van Sant, the trial court in the present case considered the alternatives to a mistrial and reasonably concluded that they were not feasible.11 The court found that a reasonable continuance was not a viable option because it was not known when Malone would be healthy enough to return. In addition, the court found that no other prosecutor would be able to substitute for Malone because of the complexity of the case.12 This finding was based on *16Whalen’s representations in chambers and on the record, as well as the court’s own observations, that the case was “very complex . . . .” Specifically, the court noted that the state already had offered more than 300 exhibits into evidence but had not yet reached “the heart of the case . . . .” The court further observed that the forensic accountants had not yet testified and that their testimony was expected to be lengthy. The court also considered the practicality of granting a lengthy continuance and its possible effect on all involved in the trial. See State v. Van Sant, supra, 198 Conn. 384 (“[t]he decision [of] whether [a] mistrial is manifestly necessary is ‘a practical matter’ ”). Specifically, the court observed that there were “jurors who [were] already chomping at the bit . . . because of the time constraints that [the court] had originally estimated and because of the fact that these jurors [had] things that they had planned to do.” The court was concerned that, if it had granted a lengthy continuance, it might have negatively impacted the impartiality of the jurors. See State v. Autorino, 207 Conn. 403, 411-12, 541 A.2d 110 (trial court’s evaluation of significance of possible juror bias is “entitled to special respect”), cert. denied, 488 U.S. 855, 109 S. Ct. 144, 102 L. Ed. 2d 116 (1988). In particular, the court stated, “obviously, we have jurors to consider, who will be asked to decide the guilt or nonguilt of [the defendants]. . . . And I certainly would not want it to be to the [defendants’] detriment that we ask the [jurors] to come back under duress, so to speak, sometime in September ... at absolute best, to decide [the defendants’] guilt or non-guilt.” In sum, we conclude that our decision in Van Sant supports our conclusion in the present case that the trial court did not abuse its discretion in declaring a mistrial.

Our conclusion also is consistent with the decisions of courts from other jurisdictions that have reviewed *17the propriety of a trial court’s declaration of a mistrial on the ground of manifest necessity following the illness or death of a prosecutor. The general consensus that emerges from these cases is that a court properly exercises its discretion in declaring a mistrial when a prosecutor becomes seriously ill during trial such that he requires a lengthy absence, and no other prosecutor is able to step in to resume the trial within a reasonable period. See Green v. State, 52 Ark. App. 244, 248, 917 S.W.2d 171 (1996) (manifest necessity established when prosecutor became ill and substitution of deputy prosecutor was precluded by virtue of deputy prosecutor’s conflict with one juror); State v. Critelli, 237 Iowa. 1271, 1273, 1278-79, 24 N.W.2d 113 (1946) (trial court properly declared mistrial when prosecutor became ill during trial, no other prosecutor could step in within reasonable time because of complexity of case, and jury had been sequestered); State v. Saavedra, 108 N.M. 38, 40-43, 766 P.2d 298 (1988) (mistrial reasonable when one week continuance necessitated by illness of defense counsel was followed by prosecutor’s scheduled back surgery and neither defendant nor state could obtain substitute counsel due to complexity of case); State v. Kirby, 269 S.C. 25, 29-30, 236 S.E.2d 33 (1977) (manifest necessity established when prosecutor died during trial and assistant prosecutor was unable to take over because he was “totally unprepared to prosecute the remainder of the case” and “in no emotional condition to continue the case”). Conversely, courts in other jurisdictions have held that the declaration of a mistrial on the basis of the illness of the prosecutor is not reasonable when a substitute prosecutor could have resumed the prosecution, when a reasonable continuance could have resolved the problem or when the record contained inadequate findings. See United States v. Watson, 28 F. Cas. 499, 500-501 (S.D.N.Y. 1868) (No. 16,651) (mistrial not reasonable when record did not indicate *18that prosecutor’s illness occurred after jury was sworn or that it was impossible for another prosecutor to conduct trial); People v. McJimson, 135 Cal. App. 3d 873, 879-81, 185 Cal. Rptr. 605 (1982) (mistrial not reasonable when prosecutor was absent due to short-term illness and substitute prosecutor could have been assigned to case); Jourdan v. State, 275 Md. 495, 510-12, 341 A.2d 388 (1975) (no manifest necessity when prosecutor became ill from exhaustion during trial and another prosecutor could have been prepared within short period of time to conduct trial or trial could have been continued for few days until another prosecutor could resume prosecution). The present case is akin to those of our sister jurisdictions in which the declaration of a mistrial was held to have been reasonable because Malone’s illness was serious such that he required a lengthy absence, and no other prosecutor was able to step in to conduct the trial due to the complexity of the case.

Notwithstanding the reasonableness of the trial court’s exercise of discretion in the present case, the defendants claim that the trial court’s finding of manifest necessity was improper because the trial court failed to explore the alternative of a “reasonable, even if somewhat lengthy, continuance in order to allow another [prosecutor] to assume responsibility for the case.” Specifically, the defendants claim that the trial court’s reliance on Whalen’s uncontroverted representations that, due to the complexity of this case, another prosecutor would not be able to replace Malone, was, “without more . . . insufficient to outweigh [the] defendants’ valued right to have the original jury decide the case.” In addition, the defendants claim that the trial court improperly failed to poll the jurors on their “availability in September [of 2007], or beyond.” (Emphasis in original.) These claims have no merit.

*19First, as we previously discussed, the record clearly indicates that the trial court considered the alternative of a lengthy continuance but reasonably rejected such alternative on the basis of its finding that no other prosecutor was able to step in within a reasonable amount of time due to the complexity of the case, and out of concern that a lengthy continuance might negatively impact the impartiality of the jurors. In making its findings, the trial court was entitled to credit Whalen’s representations regarding the unavailability of a substitute prosecutor. See State v. Michael J., supra, 274 Conn. 335 (“[Attorneys are officers of the court, and when they address the judge solemnly upon a matter before the court, their declarations are virtually made under oath. . . . Thus, the trial court was entitled to credit the prosecutor’s assertions and could have relied on them in support of its finding . . . .” [Citation omitted; internal quotation marks omitted.]); see also State v. Van Sant, supra, 198 Conn. 383 (“[A] trial court considering the exigencies of a potential mistrial situation cannot be bound by the strict rules of evidence applicable at formal proceedings .... In such a situation a court must be free to act [on] the information at hand, [as] long as it is reliable.” [Internal quotation marks omitted.]). We find it significant that the trial court’s findings regarding the feasibility of replacing Malone with another prosecutor were based in part on the court’s own observations regarding the complexity of the case. Moreover, the defendants never challenged Whalen’s representations or the trial court’s own observation that the case was “very complex” prior to the court’s declaration of the mistrial. To the contrary, when defense counsel was afforded the opportunity to address the trial court, he acknowledged that the case was complex and merely argued that “the state . . . should have been prepared” and that “it would have been wise [for] the state [to have obtained] a second *20lawyer in a case like this [one].” Finally, on appeal, the defendants have not cited to any legal authority in support of their claim that the trial court’s reliance on Whalen’s representations, by itself, was insufficient as a matter of law to justify the declaration of a mistrial.13 *21Under these circumstances, we cannot conclude that the trial court abused its discretion in declaring a mistrial.

The defendants’ claim that the trial court improperly failed to poll the jurors on their “availability in September [of 2007], or beyond(emphasis in original); also is without merit. The defendants claim that our decision in State v. Tate, 256 Conn. 262, 773 A.2d 308 (2001), required the trial court to poll the jurors as to their availability after a continuance as part of the court’s duty to explore alternatives to declaring a mistrial. We disagree and conclude that the defendants’ reliance on Tate is misplaced. In Tate, “the defendant [James Tate] asked the trial court to inquire of the jury reporting its deadlock whether it had, in fact, reached a partial verdict.” Id., 285. Tate argued that, if the jury had found him not guilty of the murder charge but was deadlocked with respect to one of the lesser included offenses, then the state would be precluded from retrying him on the ground of double jeopardy. See id., 275, 285-86. The trial court declined Tate’s request and, over Tate’s objection, declared a mistrial. Id., 285-86. On appeal, we held that the trial court improperly declared a mistrial and concluded that the trial court should have polled the *22jury, as Tate requested, because, “[h]ad the jury been asked whether it had reached a verdict on the murder charge, public justice would not have been defeated, or even compromised.” Id., 286. If the jury responded that it had not reached a verdict on the murder charge, then there would have been a proper basis for a mistrial. Id. If, however, the jury had found Tate not guilty of the murder charge but was deadlocked with respect to one of the lesser included offenses, then Tate would have been entitled to an acquittal on the murder charge, and his “valued right [to have his trial completed by a particular tribunal] would have been upheld.” (Internal quotation marks omitted.) Id. Therefore, “[t]here was no necessity at all ... to declare a mistrial before making the inquiry requested.” (Emphasis added.) Id. In Tate, we explicitly emphasized, however, that, “in the absence of a request,” the trial court does not have “an obligation to make such an inquiry of the jury [sua sponte].” Id., 286 n.16.

Tate is clearly distinguishable from the present case. Unlike in Tate, the subject of the requested inquiry in this case was not whether the jurors had reached a partial verdict but, rather, the jurors’ availability after a lengthy continuance. In addition, unlike the usefulness of the jury inquiry in Tate, a jury inquiry in the present case would have been futile in light of the uncertainty regarding when Malone would be able to return to trial and the impracticality of having another prosecutor step in mid-trial. See State v. Van Sant, supra, 198 Conn. 382 (continuance not feasible because “[t]here was no fair basis [on] which to estimate when [the witness] could testify”). Lastly, unlike the defendant in Tate, the defendants in the present case did not ask the court to make any inquiry of the jury.14 Accordingly, Tate is inapposite, and the defendants’ claim is without merit.

*23The decision denying the defendants’ motion to dismiss is affirmed.

In this opinion ROGERS, C. J., and PALMER, VERTE-FEUILLE and McLACHLAN, Js., concurred.

dissenting. It is black letter law that, as a part of the constitutional protection against multiple prosecutions, “ ‘the [d]ouble [j]eopardy [c]lause affords a criminal defendant a valued right to have his trial completed by a particular tribunal.’ Oregon v. Kennedy, 456 U.S. 667, 671-72, 102 S. Ct. 2083, 72 L. Ed. 2d 416 (1982).” State v. Butler, 262 Conn. 167, 174, 810 A.2d 791 (2002). In order to safeguard this right adequately, before a trial court properly may declare a mistrial, it is the state’s heavy burden to prove manifest necessity and the trial court’s responsibility to give due consideration to feasible alternatives in determining whether the state has satisfied that burden. Although a trial court’s decision to order a mistrial is entitled to some deference, in my view, in the present case, it acted improperly because the process by which it reached that determination does not reflect the requisite scrupulous, sound exercise of discretion. I reach this conclusion because the record did not reflect an adequate basis to inform the court’s decision to order a mistrial in lieu of other alternatives. Specifically, there was an inadequate basis from which the trial court could make a reasoned determination that it was not feasible to order a continuance to allow substitute counsel to take over the case for the state. That deficiency resulted from both the state’s failure to provide relevant information to the trial court and the trial court’s failure to make appropriate inquiries. Because the majority’s *24sanction of this inadequate effort is unduly deferential1 *25and inconsistent with the constitutional rights of the defendants, Richard Anderson and Janice Anderson, I respectfully dissent.

The majority has set forth the general principles regarding declarations of mistrial, which need not be repeated. I would highlight, however, the following essential obligations of the state, the trial court and the reviewing court. “[T]he words manifest necessity appropriately characterize the magnitude of the prosecutor’s burden. Arizona v. Washington, [434 U.S. 497, 505, 98 S. Ct. 824, 54 L. Ed. 2d 717 (1978)]. . . . [That] burden is a heavy one. ... Id. ... [A] high degree of necessity is required before a conclusion may be reached that a mistrial is appropriate .... Id., [506].” (Emphasis added; internal quotation marks omitted.) State v. Tate, 256 Conn. 262, 278, 773 A.2d 308 (2001). “A trial judge must therefore engage in a 'scrupulous exercise of judicial discretion’; United States v. Jorn, [400 U.S. 470, 485, 91 S. Ct. 547, 27 L. Ed. 2d 543 (1971)];2 *26in order to ‘assure himself that the situation warrants action on his part foreclosing the defendant from a potentially favorable judgment by the tribunal.’ Id., 486.” (Emphasis added.) State v. Buell, 221 Conn. 407, 415, 605 A.2d 539, cert. denied, 506 U.S. 904, 113 S. Ct. 297, 121 L. Ed. 2d 221 (1992). “All possible alternatives to a mistrial must be considered, employed and found wanting before declaration of a mistrial over the defendant’s objection is justified. State v. Pugliese, 120 N.H. 728, 730, 422 A.2d 1319 (1980).” (Emphasis added; internal quotation marks omitted.) State v. Tate, supra, 286-87; accord United States v. Tinney, 473 F.2d 1085, 1089 (3d Cir.) (“Jorn places on the trial judge a duty to exhaust all other reasonable possibilities before deciding to foreclose [a defendant’s] option to proceed. . . . The scrupulous exercise of that discretion means that he must seek out and consider all avenues of cure to avoid trial abortion.” [Internal quotation marks omitted.]), cert. denied, 412 U.S. 928, 93 S. Ct. 2752, 37 L. Ed. 2d 156 (1973).

“A reviewing court looks for manifest necessity by examining the entire record in the case without limiting itself to the actual findings of the trial court. ... It is the examination of the propriety of the trial court’s action against the backdrop of the record that leads to the determination [of] whether, in the context of a particular case, the mistrial declaration was proper. Given the constitutionally protected interest involved, reviewing courts must be satisfied . . . that the trial judge exercised sound discretion in declaring a mistrial.” (Citations omitted; emphasis added; internal quotation marks omitted.) State v. Van Sant, 198 Conn. 369, 379, 503 A.2d 557 (1986); accord United States v. *27Scott, 437 U.S. 82, 96, 98 S. Ct. 2187, 57 L. Ed. 2d 65 (1978) (“a trial judge’s characterization of his own action cannot control the classification of the action” [internal quotation marks omitted]). Sound discretion requires that, although the trial court need not state expressly its findings on the record, the record must reflect an adequate factual basis to inform the court’s reasoned decision to order a mistrial in lieu of other alternatives that would allow the trial to continue.3 See Arizona v. Washington, supra, 434 U.S. 517 (no constitutional impropriety when “basis for the trial judge’s mistrial order is adequately disclosed by the record” to demonstrate “deliberate exercise of his discretion”); *28see also United States v. Lara-Ramirez, 519 F.3d 76, 84-85 (1st Cir. 2008) (“Our task on appeal is to determine whether the district judge’s declaration of a mistrial was reasonably necessary under all the circumstances. . . . We are guided in this determination by consideration of three interrelated factors: [i] whether alternatives to a mistrial were explored and exhausted; [ii] whether counsel had an opportunity to be heard; and [iii] whether the judge’s decision was made after sufficient reflection.” [Citations omitted; internal quotation marks omitted.]); United States v. Bates, 917 F.2d 388, 395-96 (9th Cir. 1990) (“When it is not patently clear that reversal is certain, the reviewing court must scrutinize the record, since the Supreme Court requires the courts of appeal to ascertain that the trial court exercised its discretion properly in the circumstances that confronted it. The Supreme Court and appellate courts have relied on four indicators in determining whether the trial court abused its discretion. Has the trial judge [1] heard the opinions of the parties about the propriety of the mistrial, [2] considered the alternatives to a mistrial and chosen the alternative least harmful to a defendant’s rights, [3] acted deliberately instead of abruptly, and [4] properly determined that the defendant would benefit from the declaration of mistrial?”). In determining whether the granting of a mistrial has violated the double jeopardy clause, “[w]e resolve any doubt in favor of the liberty of the citizen, rather than exercise what would be an unlimited, uncertain, and arbitrary judicial discretion.” (Internal quotation marks omitted.) Downum v. United States, 372 U.S. 734, 738, 83 S. Ct. 1033, 10 L. Ed. 2d 100 (1963); accord Sanchez v. United States, 919 A.2d 1148, 1151 (D.C. 2007).

Turning to the facts of the present case, I agree that the trial court did not abuse its discretion in deciding that continuing the case until Senior Assistant State’s *29Attorney John Malone recovered from his illness was not a feasible alternative to declaring a mistrial. The trial court directly communicated with Malone to affirm his unavailability and to assess the seriousness of his condition and, as a result, learned of Malone’s diagnosis of pneumonia and imminent hospitalization. There is nothing in the record to raise any question as to the veracity of these facts. In light of the facts gleaned upon this inquiry, the trial court reasonably concluded that Malone’s return date was too indeterminate to allow a continuance pending his return.

The aforementioned inquiry and the facts gleaned from that inquiry stand in stark contrast to the basis, however, for the trial court’s determination that it was not feasible to order a continuance to allow substitute counsel to take over the case. The only statement made on the record by the state relative to this matter was the following sweeping, self-serving statement by State’s Attorney John Whalen: “I don’t think anyone could step in at this point and try to salvage this case until [Malone] returns or finish it if he doesn’t return.”4 (Emphasis added.) Whalen did not represent that anyone from his office actually had inquired into the availability of other state’s attorneys in the crime fraud unit to take over the case, nor, if such an inquiry had been made, how this ultimate determination had been reached. Cf. United States v. Lynch, 598 F.2d 132, 135-36 (D.C. Cir. 1978) (no abuse of discretion to order mistrial on basis of judge’s illness after initial two week continuance and *30administrative judge’s later inquiries determined that no other judges were available to substitute), cert. denied, 440 U.S. 939, 99 S. Ct. 1287, 59 L. Ed. 2d 498 (1979). Nor did he provide any information to the court about the preparation time that would be necessary for such a substitution, information that could have been obtained from Malone.5 Whalen never brought to the court’s attention the fact that other members of the office of the chief state’s attorney previously had been involved in the case,6 and there is no evidence that anyone from that office had ascertained whether assistance by these staff members could minimize the preparation time for substitute counsel. In sum, the state did nothing to prove that a continuance with substitute counsel was not a feasible option. Accordingly, on the *31basis of this record, the state’s position essentially was, first, as evidenced by Whalen’s statement, that no one other than Malone could prosecute the case, and, second, as evidenced by the state’s failure to provide any relevant information to the court, that the trial court should defer to the state’s assessment of the feasibility of continuing the case with substitute counsel. Under these circumstances, I question how the state met its “heavy” burden of proving that a mistrial was a manifest necessity.

Despite the state’s failure to provide such information and its responsibility in creating the situation at hand by assigning only one attorney to what it now characterizes as a highly complicated case,7 the trial court made no inquiries on the record regarding facts relevant to the feasibility of a continuance with substitute counsel. In the absence of a clear record, however, such inquiries are an essential aspect of the soundness of the exercise of the court’s discretion. Compare Fulton v. Moore, 520 F.3d 522, 529 (6th Cir. 2008) (concluding that manifest necessity standard was met when, inter alia, trial judge “asked defense counsel how long a period would be needed to prepare under the amended indictment, demonstrating that he considered calling the jury back at a later date”) with United States v. Lara-Ramirez, supra, 519 F.3d 87 (“Although the [District [C]ourt has broad discretion to fashion an appropriate procedure for assessing whether the jury has been exposed to substantively damaging information, and if so, whether cognizable prejudice is an inevitable and ineradicable concomitant of the jury’s exposure to an improper outside influence . . . the judge does not have discretion *32to refuse to conduct any inquiry at all regarding the magnitude of the taint-producing event and the extent of the resulting prejudice. Accordingly, the [District [C]ourt’s investigation in this case fell short of the scrupulous exercise of judicial discretion required to support the mistrial declaration.” [Citation omitted; internal quotation marks omitted.]) and Camden v. Circuit Court of the Second Judicial Circuit, 892 F.2d 610, 621 (7th Cir. 1989) (Posner, J., dissenting) (reaching manifest necessity issue not reached by majority and concluding that no manifest necessity existed for mistrial on basis of juror bias when trial court had failed to make inquiry to jurors and biased juror could be replaced with alternate). The trial court apparently determined that it could glean sufficient facts from the record to conclude that the state had met its burden of establishing manifest necessity. I therefore turn to those facts.

First, the trial court, Schimelman, J., stated that the case was complicated, pointing to the more than 300 exhibits that had been submitted in the eight days of trial as evidence of that fact, and, therefore, concluded that substitute counsel would require significant preparation time. I would agree that the case was not a simple one.8 A review of the record makes clear, however, that the overwhelming majority of the exhibits submitted were simply checks that had been introduced in short order on a single day of trial.9 The record also reflects *33that the most complicated testimony, that of the forensic accountants, had not yet begun. Therefore, a continuance would not have impaired the jury’s ability to recall the most complicated aspects of the case.

Second, the trial court pointed to the fact that there were jurors who were impatient because of the original trial schedule of five and one-half weeks, plans that jurors had made and the delay that already had occurred.10 The trial court stated on the record, however, that it had considered polling the jury to determine whether a continuance until September, 2007, was feasible when it had thought that Malone might be able to return by then. It did not explain why such a continuance was a viable option under those circumstances, but not for substitute counsel. Of course, because the state had provided no date by which it could be prepared to proceed with substitute counsel and the trial court declined to inquire into that matter, the court had no basis on which to poll the jury as to its availability in September or any other time. See United States v. Lara-Ramirez, supra, 519 F.3d 87-88 (“In its written opinion denying [the defendant’s] motion to dismiss, the court stated that, ‘[i]n view of all the circumstances, cautioning the jurors as to their ability to render a verdict discarding any reference to the Bible would have been self-defeating.’ We do not understand the basis for these generalities. Although a more developed record might have supported findings that the Bible had played a central role in deliberations and that individual jurors would not have been able to disregard its influ*34ence, we see no basis for such findings in this record.”); United States ex rel. Russo v. Superior Court, 483 F.2d 7, 15-16 (3d Cir. 1973) (concluding that trial court’s determination that jury was too exhausted to continue deliberations improper in absence of inquiries as to jurors’ physical condition or their progress toward reaching verdict and citing United States v. Lansdown, 460 F.2d 164, 169 [4th Cir. 1972], which held that conclusion of inability of jury to reach verdict must be supported by “something in addition to” trial court’s decision that jury had deliberated “long enough”), cert. denied, 414 U.S. 1023, 94 S. Ct. 447, 38 L. Ed. 2d 315 (1973).

With regard to the jury, however, there is no indication that the trial court gave any weight to the fact that it had taken one month to select this jury. Nor is there any indication that the court considered the fact that there were four alternate jurors, some of whom might have been willing to serve in the place of any of the six jurors who might have been unavailable at a later date. Rather, the trial court suggested that, if it were to order a continuance, the jury might be prejudiced against the defendants. The defendants, however, had asserted their desire to continue with this jury. In the absence of some concrete reason to believe that the jury would have such bias, the trial court’s speculation should not override the defendants’ “valued right to have [their] trial completed by a particular tribunal.” (Internal quotation marks omitted.) State v. Butler, supra, 262 Conn. 174; see also United States v. Shafer, 987 F.2d 1054, 1058 (4th Cir. 1993) (“As an initial matter, we must put aside any statements by the [District [C]ourt that the mistrial was partially motivated by concerns of prejudice to the defense. . . . We note that such reservations were not shared by [the defendant], who wanted the trial to continue.” [Citations omitted.]).

*35In sum, I do not intend to suggest that the state’s failure to provide, and the trial court’s failure to inquire about, every fact that might be relevant to whether an alternative is feasible will render a mistrial order improper. Moreover, I am open to the possibility that the actual facts might have justified the conclusion that a continuance was not feasible. The record in the present case, however, does not reflect sufficient facts to have allowed the trial court to exercise sound, scrupulous discretion in rejecting the alternative of a continuance. Therefore, “[t]he court’s failure to conduct an adequate investigation leaves us with a record that does not support the finding that the mistrial was manifestly necessary. In the absence of such record support, [the defendants’] valued right to have [their] trial completed by a particular tribunal is not to be foreclosed.” (Internal quotation marks omitted.) United States v. Lara-Ramirez, supra, 519 F.3d 89.

Accordingly, I respectfully dissent.
