**120 This appeal raises the question of whether the trial court's refusal to sever two unrelated criminal cases brought against the defendant, Eddie A. Perez, previously joined for trial for purposes of judicial economy, improperly compromised the defendant's **121 right to choose whether to testify on his own behalf in one of the cases but to remain silent in the other. The Appellate Court concluded that it did, reversed the judgments of conviction and remanded the cases to be retried in two separate proceedings. 1 *656 State v. Perez, 147 Conn.App. 53 , 93, 124, 80 A.3d 103 (2013). Thereafter, the state, on the granting of certification, appealed, contesting the propriety of this determination. 2 It contends, inter alia, that the defendant's first request to sever the cases was accompanied by an inadequate offer of proof as to his need to testify and that a second request, although sufficiently detailed, was untimely. We conclude that the defendant timely made a compelling showing that he had important testimony to give in one case and a strong need to refrain from testifying in the other and, therefore, that the trial court had abused its discretion in declining to sever the cases. 3 Accordingly, we affirm the judgment of the Appellate Court.

Following a jury trial, the defendant, the former mayor of the city of Hartford (city), was convicted of bribe receiving, fabricating evidence and larceny by **122 extortion for actions he had taken while in office. 4 The state had charged the defendant with these offenses in two separate informations but, before trial, moved to consolidate the charges. The trial court granted the state's motion to consolidate over the defendant's objection, and the cases were tried together before a single jury.

The Appellate Court's opinion provides a detailed rendition of the facts underlying the defendant's convictions, which need not be repeated in this opinion. See id., at 66-77, 82-88, 80 A.3d 103 . For present purposes, however, it is necessary to briefly summarize the facts underlying the case involving the bribery and fabrication charges (bribery case). 5 The defendant was convicted of bribe receiving for accepting free home improvement services from a contractor, Carlos Costa, in exchange for the defendant's assisting Costa in connection with certain problems that Costa had encountered while his company, USA Contractors, performed a construction contract for the city. Specifically, the defendant assisted Costa by requesting that the city treasurer expedite some payments due to USA Contractors and by interfering with efforts of the Hartford Department of *657 Public Works (department) to manage the construction contract and to call USA Contractors' performance bond due to insufficient performance, an action that would have removed **123 USA Contractors from the city construction project and impaired its ability to do business with the city in the future. The defendant also was convicted of fabricating evidence in connection with his request that Costa create a bill for the home improvement work only when an investigation into the propriety of that work had commenced or was imminent.

The state's presentation of evidence in the bribery case, which preceded its presentation of evidence in the larceny by extortion case (extortion case), included the following. Department employees and outside consultants the department hired testified that USA Contractors had performed the construction contract with the city poorly and behind schedule, and that it had submitted baseless claims for additional payments. At some point, at the defendant's behest, the city's director of capital projects became involved to mediate issues that arose between the department and USA Contractors. Ultimately, because performance remained inadequate, the foregoing individuals together decided to contact USA Contractors' bonding company and to report the performance issues for the purpose of calling the bond and terminating the contract between the city and USA Contractors. When Costa informed the defendant that a letter to this effect had been sent, the defendant became upset. Thereafter, the director of capital projects wrote another letter to the bonding company rescinding the first letter, without seeking the approval of the others involved in the earlier decision. USA Contractors remained on the job and finished the project well beyond the time period contemplated by the contract with no further action taken on its performance bond.

Costa testified for the state. He agreed that he had sought the defendant's assistance with the city's expeditious payment of certain amounts due under the construction contract and with the rescission of the **124 department's letter to USA Contractors' bonding company, but, in his view, those actions were wholly justified because he was being treated unfairly and also had experienced problems with late payments by the city. He attributed many of the problems and delays associated with the project to the department, and others to circumstances that were beyond his control. Costa since had sued the city for breach of the construction contract, seeking substantial damages. He believed that the consultants the department had hired operated under a conflict of interest due to their prior involvement in the design of the project. Costa, who had a history of successfully performing other work for the city, had been acquainted with the defendant for a considerable period of time prior to any of the events in question, and considered him a friend. In addition, Costa previously had campaigned and raised funds for the defendant.

Damningly to the defendant, however, Costa also testified that, around the time he sought assistance from the defendant for the problems he was experiencing with the construction project, he was performing kitchen and bathroom renovations at the defendant's private residence without receiving any payment for such work. He confirmed that he never prepared a quote, took a deposit or expected to get paid for those renovations. Costa explained that he performed this work for free because the defendant was the mayor and his friend, he considered the work to be a cost of doing business with the city and he believed it would provide him with greater access to the defendant. According to Costa, the defendant did not begin to approach *658 him about a bill until approximately one year after the work was completed, when rumors about the work began circulating in the community. Costa could not immediately provide the defendant with a bill because he had not kept records for the renovation **125 work, believing that he would not be paid for it. He gave the defendant a bill several months later, however, and the defendant paid Costa several months after that.

A number of materials suppliers and construction workers testified to provide detail about the work performed at the defendant's residence and its substantial cost. Their testimony established that the amount the defendant ultimately paid for the home renovations was well below market rate. An employee of The Home Depot (Home Depot) testified that the defendant and his wife, prior to the work being done at their residence, had entered into an agreement with Home Depot to provide similar services but thereafter cancelled that agreement, purportedly because they had received a lower offer. The defendant's executive assistant testified that the defendant would at times meet or speak with Costa when Costa visited or called the defendant's office but that, at other times, he was not available to Costa. The city treasurer confirmed that the defendant's office requested several times that USA Contractors receive expedited payment for its construction work, and that checks were issued after auditing protocols ensured that payment was proper. A city employee testified that building permits were not issued for the work performed at the defendant's home prior to its completion. A city merchant testified that he had heard from a worker at the defendant's home that the work there had been done for free and without permits, and that he thereafter began telling many people in the community, including the defendant's political opponents, about what he had heard.

Finally, Michael Sullivan, a former investigator with the public integrity unit of the Office of the Chief State's Attorney, testified about the investigation that had led to the defendant's arrest. Sullivan had arranged to meet with the defendant and to interview him about the events underlying the extortion case but, at some point, **126 heard the rumors about Costa's free home improvement work for the defendant. The interview occurred with the city's corporation counsel also in attendance. At the conclusion of the interview, Sullivan asked the defendant whether USA Contractors had performed bathroom and kitchen renovations for him, and the defendant replied that it had. The defendant falsely claimed that he had paid for the work approximately one and one-half years prior to the interview, which was fairly close to the time the renovation work had been completed. Sullivan testified that, at this point in the interview, the defendant became noticeably nervous. The defendant agreed to provide Sullivan a copy of the cancelled check with which he purportedly had paid, but, after some delay, the defendant ultimately provided documentation indicating that he had applied for a home equity loan hours after he had met with Sullivan and subsequently paid for the renovation work with the proceeds of that loan. The defendant also provided the invoice Costa had prepared for the work several months beforehand, which Sullivan determined to be fabricated in that it was created after the fact and lacked supporting documentation. Sullivan's investigation also yielded records of telephone or cell phone calls between Costa and the defendant around the time USA Contractors received expedited payments from the city and the time the second letter was sent to USA Contractors' bonding company. Sullivan also testified that *659 he secretly had recorded his interview with the defendant, and the recording was introduced into evidence. 6

The defense case largely was presented through cross-examination of the state's witnesses. Otherwise, the defendant's chief of staff testified for the defense, explaining that the defendant's wife had encountered **127 a serious medical issue when the renovation work was being performed at the defendant's home, that she underwent multiple surgeries at different hospitals in the six month period thereafter, and that the defendant experienced difficulties in getting the family's health insurer to pay all of the resulting bills. He testified further that the defendant was very concerned and distracted by these occurrences, and that he also was busy with his mayoral duties. The chief of staff confirmed that the defendant and Costa were acquainted prior to the events in question due to Costa's campaign and fundraising assistance. He also testified that the defendant, as a general matter, prioritized supporting minority run businesses such as Costa's and would assist in getting them paid by the city. As to the bribery case, the only other witness whom the defense called was the construction worker who purportedly reported the free and unpermitted work being done at the defendant's residence. When called to the stand, he denied having done so and also stated that, in the entire time he had been at the defendant's residence, he had seen the defendant there only once.

In his memorandum in opposition to the state's pre-trial motion to consolidate, the defendant briefly mentioned that consolidation would affect his ability to exercise his right to testify but did not elaborate. On May 18, 2010, near the end of the state's presentation of its evidence in the bribery case, defense counsel notified the court and the assistant state's attorneys (state) that, when the state concluded its evidence in that case, he would be moving to sever the two cases on the ground that the defendant wished to testify in the bribery case but not in the extortion case. Defense counsel stated that this decision was based on his assessment of Costa as a witness for the prosecution, an assessment he could not have made prior to trial. The state indicated that it was opposed to severance **128 as "not appropriate," arguing that the defendant, in previously arguing against consolidation, had not claimed that he wanted to testify in one case but not the other. In the state's view, the defendant had failed to make the determination as to whether he would testify in a timely fashion, and, therefore, severance was not warranted. The court, for its part, agreed that "[i]t's something that probably should have been raised and highlighted a lot earlier."

On May 20, 2010, at the close of the state's bribery case, the defendant filed a motion to sever pursuant to Practice Book § 41-18 (first motion to sever). In addition to reiterating his previous arguments raised in his memorandum in opposition to the state's motion to consolidate, which pertained to the Boscarino factors, 7 he expressly claimed that he was prejudiced substantially by the consolidation because he wished to testify in the bribery case but to exercise his constitutional right not to testify in the extortion case. In his first motion to sever, the defendant described the testimony that he would give in the bribery case as follows: (1) "[t]he defendant's reasons for misleading ... Sullivan *660 during their initial interview on June 27, 2007"; (2) "[h]ow ... Costa became involved in the defendant's home renovation project, details regarding when [the defendant] first approached ... Costa and requested a bill, the number of times that [the defendant] personally followed up with Costa regarding his request, and the reasons for his delay in payment"; (3) "[t]he context of [the defendant's] involvement in the [second] letter ... [to USA Contractors' bonding company] regarding the [city construction] project"; and (4) "[t]he context of [the defendant's] involvement in the issuing of [expedited payments] from the [city] treasurer ... to USA Contractors." The defendant also contended in the first motion to sever that his "testimony on these points, at **129 a minimum, will be absolutely critical for the jury's complete assessment of both his intent, as well as interactions that he alone may have had with ... Costa. Thus, [the defendant's] ability to exercise his right to testify is critical because he is the sole source of information on these points." The first motion to sever also provided reasons why the defendant did not wish to testify in the extortion case, namely, that his version of the underlying facts in that case would be presented to the jury through his recorded interview with Sullivan, making his live testimony unnecessary, particularly since it would expose him to a risk of prejudicial cross-examination regarding uncharged misconduct that related only to the extortion case. 8

When the first motion to sever was argued on May 20, 2010, defense counsel reiterated that his assessment of the defendant's need to testify in the bribery case had not crystallized until he had heard the state's presentation of its evidence and could evaluate the credibility of the witnesses. According to defense counsel, it was then clear that the defendant had to testify in order to have a chance of acquittal in the bribery case. The state, in response, argued that Connecticut case law indicated that motions to sever based on a defendant's wish to testify selectively should be raised pretrial, and that the defendant should have made his argument in this regard at the time of the state's motion to consolidate. In the state's view, the defendant was making an improper and untimely "attempt ... to control the course of the case," and, moreover, it was unnecessary for the defendant to testify because the matters he had identified had been addressed adequately on cross-examination of various witnesses. After a colloquy between the court and counsel regarding the fact that our jurisprudence, at the time, supported a presumption **130 in favor of joinder, 9 the court rejected the defendant's claim that his constitutional right to testify could outweigh the interest in judicial *661 economy. Notably, the court never determined that the defendant's testimonial proffer was inadequate for it to balance those two interests, nor did it remark on the substance of that proffer.

Thereafter, on June 9, 2010, following the state's presentation of its evidence in the extortion case, the defendant renewed his arguments in a second motion to sever. 10 After a June 11, 2010 hearing at which counsel provided extensive detail as to the defendant's planned **131 testimony in the bribery case, 11 the trial court again **132 declined to sever the cases, reasoning *662 that the jury had **133 been instructed repeatedly *663 to consider the two cases separately and that the defendant remained free to testify in only one case if he so chose, with any cross-examination limited to the case about which he testified.

On appeal to the Appellate Court, the defendant argued, inter alia, that the trial court's denial of his motions to sever was improper because it constrained his right to testify; see State v. Perez, supra, 147 Conn.App. at 93, 113 , 80 A.3d 103 ; and the entire panel of that court hearing the case, although split on the question of whether the cases had been improperly joined, agreed. See id., at 113 , 80 A.3d 103 ; id., at 124-25 , 80 A.3d 103 ( Lavine, J., concurring). Specifically, the panel concluded that the trial court's refusal to sever the cases midtrial had compromised the defendant's ability to testify in the bribery case, causing him substantial prejudice. Id., at 113 , 80 A.3d 103 ; id., at 124-25 , 80 A.3d 103 ( Lavine, J., concurring). We agree with the Appellate Court that the trial court abused its discretion in declining to sever **134 the cases because the defendant's first motion to sever was filed timely and constituted a compelling showing that he had important testimony to give in one case and a strong need to refrain from testifying in the other.

It long has been recognized that joinder of unrelated criminal charges can cause unfair prejudice when it "embarrasses or confounds an accused in making his defense." (Internal quotation marks omitted.) Cross v. United States, 335 F.2d 987 , 989 (D.C.Cir. 1964). For example, "[p]rejudice may develop when an accused wishes to testify on one but not the other of two joined offenses which are clearly distinct in time, place and evidence. His decision whether to testify will reflect a balancing of several factors with respect to each count: the evidence against him, the availability of defense evidence other than his testimony, the plausibility and substantiality of his testimony, [and] the possible effects of demeanor, impeachment, and cross-examination. But if the two charges are joined for trial, it is not possible for him to weigh these factors separately as to each count. If he testifies on one count, he runs the risk that any adverse effects will influence the jury's consideration of the other count. Thus he bears the risk on both counts, although he may benefit on only one. Moreover, a defendant's silence on one count would be damaging in the face of his express denial of the other. Thus he may be coerced into testifying on the count [on] which he wished to remain silent." (Footnotes omitted.) Id.

"[B]ecause of the unfavorable appearance of testifying on one charge while remaining silent on another, and the consequent pressure to testify as to all or none, the defendant may be confronted with a dilemma: whether, by remaining silent, to lose the benefit of vital testimony on one count, rather than risk the prejudice (as to either or both counts) that would result from testifying on the other. Obviously no such dilemma **135 exists [when] the balance of risk and advantage in respect of testifying is substantially the same as to each count." Baker v. United States, 401 F.2d 958 , 976 (D.C.Cir. 1968).

Undue prejudice will not invariably result from a decision to testify selectively. Consequently, "[a]n accused's election to testify on some but not all of the charges on trial does not automatically require a severance." (Internal quotation marks omitted.) State v. King, 187 Conn. 292 , 304, 445 A.2d 901 (1982), overruled in part on other grounds by State v. Payne, 303 Conn. 538 , 34 A.3d 370 (2012). Rather, the matter remains within the trial court's discretion, "though a discretion within limits narrowly confined by the exigencies of the situation. In the end, it is *664 incumbent [on] the judge to weigh the considerations of economy and expedition in judicial administration against the defendant's interest in having a free choice with respect to testifying, and to grant or deny the severance accordingly." (Internal quotation marks omitted.) State v. King, supra, at 304, 445 A.2d 901 . Although "trial courts must be afforded reasonable latitude in exercising discretion in these matters, [it bears emphasis] that compromise of a defendant's fundamental right to a fair trial free of undue prejudice as the quid pro quo for the mere expeditious disposition of criminal cases will not be tolerated." People v. Lane, 56 N.Y.2d 1 , 8, 436 N.E.2d 456 , 451 N.Y.S.2d 6 (1982).

In State v. Schroff, 198 Conn. 405 , 408-409, 503 A.2d 167 (1986), we adopted the analysis that federal courts use when a criminal defendant contends that severance of the charges is necessary because he or she wishes to testify as to some charges but not as to others. Pursuant to that approach, "no need for a severance exists until the defendant makes a convincing showing that he has both important testimony to give concerning one count and [a] strong need to refrain from testifying **136 on the other. In making such a showing, it is essential that the defendant present enough information-regarding the nature of the testimony he wishes to give on one count and his reasons for not wishing to testify on the other-to satisfy the court that the claim of prejudice is genuine and to enable it intelligently to weigh the considerations of economy and expedition in judicial administration against the defendant's interest in having a free choice with respect to testifying." (Internal quotation marks omitted.) Id., at 409, 503 A.2d 167 , quoting Baker v. United States, supra, 401 F.2d at 977 .

We conclude that the trial court improperly denied the defendant's first motion to sever because the motion was timely filed and his accompanying proffer, as to his need to testify in the bribery case, was sufficient to meet the foregoing standard. At that point in the proceedings, the defendant adequately demonstrated that his interest in testifying on his own behalf in the bribery case outweighed the considerations of judicial economy that had justified joinder at the outset of trial.

The defendant was convicted of receiving a bribe pursuant to General Statutes § 53a-148 (a), which provides in relevant part: "A public servant ... is guilty of bribe receiving if he solicits, accepts or agrees to accept from another person any benefit for, because of, or as consideration for his decision, opinion, recommendation or vote." A distinguishing feature of the crime of bribery, with respect to the recipient of a bribe, is that it "requires intent ... to be influenced in an official act...." (Internal quotation marks omitted.) United States v. Sun-Diamond Growers of California, 526 U.S. 398 , 404, 119 S.Ct. 1402 , 143 L.Ed.2d 576 (1999). 12 "In other words, for bribery there must be a **137 quid pro quo-a specific intent to ... receive something of value in exchange for an official act." (Emphasis is original.) Id., at 404-405 , 119 S.Ct. 1402 . Stated otherwise, the benefit that the public official receives is "the prime mover or producer *665 of [his or her] official act." (Internal quotation marks omitted.) United States v. Strand, 574 F.2d 993 , 995 (9th Cir. 1978). If direct evidence of the requisite intent is unavailable, it may be established, as it was in the present case, by circumstantial evidence. See, e.g., United States v. Jennings, 160 F.3d 1006 , 1014 (4th Cir. 1998). "The quid pro quo requirement is satisfied [as] long as the evidence shows a course of conduct of favors and gifts flowing to a public official in exchange for a pattern of official actions favorable to the donor." (Emphasis in original; internal quotation marks omitted.) Id.

Under the law governing bribery, it was essential for the state to prove, beyond a reasonable doubt, that the defendant had accepted a benefit from Costa, namely, free home improvement services. The state also needed to prove, beyond a reasonable doubt, that the defendant undertook one or more official acts, such as interfering with the department's decisions to call USA Contractors' bond and to remove USA Contractors from the job, or requesting that the city treasurer expedite payments due to USA Contractors, in exchange for that benefit. Stated otherwise, the state needed to show that the motivating force for the defendant's taking of these actions was his receipt of a benefit from Costa, and not his independent judgment that the actions were a proper and warranted exercise of his mayoral authority.

When the state rested in the bribery case, its evidence tended to show that (1) the defendant received substantial **138 home improvement services from Costa, with whom he previously was friendly, without any advance payment or an agreed on price, (2) at various times in the two years that followed, the defendant assisted USA Contractors, Costa's business entity, in getting paid and remaining on the city construction contract, despite USA Contractors' questionable performance, (3) the defendant did not get a bill for the home improvement services until more than one year after they were completed, and that bill stated an amount that was below market cost for the services rendered, (4) the defendant did not pay the bill until several months later, after he was questioned by an investigator, and (5) the defendant, when questioned by that investigator, appeared nervous and falsely reported that he previously had paid for the services. Without an effective rebuttal by the defense, the state's proof that the defendant had received a benefit from Costa in exchange for official acts was quite strong.

We conclude that the defendant's description in his first motion to sever of the testimony that he would give, when viewed against the foregoing evidence offered by the state, adequately enabled the trial court to weigh the defendant's interest in testifying against the countervailing consideration of judicial economy and, moreover, that the trial court's denial of the defendant's request for severance at that point was an abuse of discretion that prejudiced the defendant substantially. To begin, it bears emphasis that the trial court, in denying the first motion to sever, did not state that the defendant's testimonial proffer was in any way inadequate for it to engage in that balancing of interests, nor did it even comment on the substance of that proffer. Rather, the court appeared to deny the first motion to sever on the basis of untimeliness and general deference to the presumption in favor of joinder that existed at the time the cases were tried. Impairment of the choice **139 whether to testify, however, is a recognized form of prejudice that may override that presumption in certain circumstances. *666 13 Under our rules of practice and jurisprudence, the defendant was entitled to request severance on this basis midtrial, and it was "incumbent [on] the [court] to weigh the considerations of economy and expedition in judicial administration against the defendant's interest in having a free choice with respect to testifying, 14 and to grant or deny the severance accordingly." (Footnote added; internal quotation marks omitted.) State v. King, supra, 187 Conn. at 304 , 445 A.2d 901 .

Next, the defendant's proffered testimony clearly had the potential to undermine the state's evidence of bribery and, therefore, to provide the defendant a meaningful chance of an acquittal on that charge. Specifically, the defendant proposed to testify regarding when he first sought a bill from Costa, the number of times he followed up on that request and the reasons for his delay in payment. He also offered to provide an explanation as to why he had misled Sullivan regarding the timing of **140 his payment. If the defendant could convince the jury that he had intended to pay for the renovation work all along, that he had attempted to do so much earlier than the state had contended and that he had a good reason for the delay in payment, it would rebut the evidence that the defendant had accepted a benefit from Costa, an essential element of bribery. 15

With respect to the defendant's false statement to Sullivan, we agree with the Appellate Court's apt assessment that "[t]he need to rehabilitate [that untruth] is evident, and, to do that, the defendant's testimony was required." State v. Perez, supra, 147 Conn.App. at 123 , 80 A.3d 103 . In his first motion to sever, the defendant also indicated that he would explain "[t]he context of his involvement" in both the second letter to USA Contractors' bonding company and the expedited payments to USA Contractors. Because there was evidence tending to show that neither of those courses of action necessarily was unwarranted, it was likely that the defendant would have explained that he undertook them for reasons entirely unrelated to his receipt of a benefit from Costa, thereby negating the state's circumstantial proof of an illegal quid pro quo. 16

*667 **141 Weighing the defendant's need to testify in one case and his need to refrain from testifying in the other against considerations of judicial economy, we conclude that the trial court's denial of the defendant's first motion to sever was an abuse of discretion because joinder of the cases, at that point in time, caused the defendant substantial prejudice. As we previously noted, the defendant had a strong interest in testifying in the bribery case on the points that he identified, so as to refute the state's case that he had received free home renovations in exchange for his official acts. Furthermore, it is not disputed that the defendant gave adequate reasons for wishing to refrain from testifying in the extortion case. See footnote 8 of this opinion. Insofar as the state had yet begun presenting its case with respect to the charges of larceny by extortion, neither the state nor the court had expended significant resources trying that case. Consequently, the cost to judicial economy of permitting a severance of the charges at that point was relatively low. Because the denial of a free choice to testify in only the bribery case deprived the defendant "of an appreciable chance for an acquittal [on the bribery charge], a chance that [he] would have had in a severed trial"; (internal quotation marks omitted) United States v. Little Dog, 398 F.3d 1032 , 1037 (8th Cir. 2005) ; the result, in our view, was serious prejudice.

The state contends instead that the trial court properly denied the defendant's first motion to sever because it was insufficiently detailed for the court to evaluate his claim of prejudice. This reasoning, however, ignores the actual basis of the court's ruling. As we previously explained, the trial court, in ruling on the first motion to sever, did not reject the defendant's testimonial proffer as insufficient or even discuss that proffer or address the governing legal standard. Rather, it appears that the court denied the first motion to sever **142 on the basis of untimeliness and the preexisting general presumption in favor of joinder. In any event, the defendant's proffer was sufficient to meet the governing legal standard. Our research reveals that, in the usual case in which a court reviewing a claim that a defendant's right to testify was impaired by joinder rejects that claim due to an insufficient testimonial proffer, it is because the proffer at issue was entirely bereft of information that would have enabled the court to engage in the required balancing of interests. 17 That simply is not the case here. *668 **143 We are further unconvinced by the state's contention that the defendant was not prejudiced by the court's ruling because his proposed testimony was insignificant, unbelievable or cumulative to other testimony. As we noted, the defendant's proposed testimony clearly was relevant to the elements of bribery, offering him a reasonable chance of acquittal, and whether it was credible ultimately was a question for the jury. See, e.g., United States v. Sampson, 385 F.3d 183 , 190-93 (2d Cir. 2004) (defendant was prejudiced when proposed testimony could have refuted state's evidence as to his identity as perpetrator of drug sale), cert. denied, 544 U.S. 924 , 125 S.Ct. 1642 , 161 L.Ed.2d 483 (2005) ; cf. United States v. Valentine, 706 F.2d 282 , 291 (10th Cir. 1983) (defendant was not prejudiced when proposed testimony would not have related to element of crime charged). Moreover, it could not be entirely cumulative of testimony already elicited on cross-examination, particularly insofar as it concerned the defendant's own subjective intentions. Although defense counsel's cross-examination of Costa suggested that the defendant would attribute his delayed payment for the home improvement work to his wife's illness and his assisting Costa to reasons unrelated to the home improvement work, there was no substitute for the jury's observation of the defendant's own testimony regarding those matters **144 and any explanations that he may have had. See, e.g., United States v. Jordan, 112 F.3d 14 , 17-18 (1st Cir.) (defendant was prejudiced when proposed testimony as to his subjective intent could have provided good faith defense to tax *669 fraud and false tax return charges, and testimony of his attorney was not effective substitute), cert. denied, 522 U.S. 923 , 118 S.Ct. 318 , 139 L.Ed.2d 245 (1997) ; cf. United States v. Valentine, supra, at 291 (defendant was not prejudiced when his proposed testimony that guns were brought to his residence by third party, whom he had contacted in effort to have them removed, was cumulative of that party's testimony as to same facts). As the defendant himself explained in his first motion to sever, his testimony was "absolutely critical for the jury's complete assessment of ... his intent ... [and] because he is the sole source of information on these points."

Saving government resources through judicial economy is a legitimate concern. On the other side of the scale, however, is a defendant's right to a fair trial at which his constitutional right to testify on his own behalf has not been unfairly impeded. As the core jurisprudence in this area recognizes, testifying in one case while remaining silent in another is, in and of itself, prejudicial to a defendant. See, e.g., Baker v. United States, supra, 401 F.2d at 976 (acknowledging "the unfavorable appearance of testifying on one charge while remaining silent on another"); Cross v. United States, supra, 335 F.2d at 989 ("a defendant's silence on one count would be damaging in the face of his express denial of the other"). Notably, the defendant in the present case consistently and repeatedly fought consolidation and sought severance of the charges against him throughout the trial court proceedings. In recognition of the fact that juries are suspicious of defendants who choose to testify selectively, the defendant ultimately chose to remain silent in both of his cases. If severance had been **145 afforded, his choice would not have been so constrained. In light of the potentially persuasive defense in the bribery case set forth in the defendant's first testimonial proffer, which was timely presented to the court, we conclude that judicial economy should have given way to the defendant's opportunity to present that case to a jury free of the significant prejudice that necessarily flowed from the court's denial of his motion to sever. See People v. Lane, supra, 56 N.Y.2d at 8 , 436 N.E.2d 456 ("compromise of a defendant's fundamental right to a fair trial free of undue prejudice as the quid pro quo for the mere expeditious disposition of criminal cases will not be tolerated").

The judgment of the Appellate Court is affirmed.

In this opinion ROGERS, C.J., and McDONALD and ROBINSON, Js., concurred.

VERTEFEUILLE, J., with whom ZARELLA, J., joins, dissenting.

Deciding whether to sever two or more informations against a defendant that have been joined for a single trial calls for a trial court to exercise discretion and balance considerations of judicial economy against the likelihood that the joint trial will prejudice the defendant. The trial court in the present case, after balancing these competing considerations, joined for trial two informations that charged the defendant, Eddie A. Perez, former mayor of Hartford, with separate, corruption related offenses-one of the alleged crimes relating to an alleged bribe; the other crimes relating to an alleged extortion attempt. The court thereafter denied two separate motions by the defendant to sever the informations. Following his conviction of various corruption related offenses after a jury trial, the defendant appealed to the Appellate Court, which reversed the trial court's judgments and remanded the **146 cases for new, separate trials. State v. *670 Perez, 147 Conn.App. 53 , 124, 80 A.3d 103 (2013).

The majority concludes that the trial court in the present case abused its discretion by denying the defendant's first motion to sever because he wanted to testify in the bribery case, but not in the extortion case. In my view, however, the majority has not afforded the trial court's exercise of discretion the level of deference to which it is entitled. Because I am persuaded that the trial court acted properly within its discretion in declining to sever the cases on this basis, I respectfully dissent. 1

**147 In considering whether to sever two cases that have been joined for trial, "the trial court enjoys broad discretion, which, in the absence of manifest abuse, an appellate court may not disturb." (Internal quotation marks omitted.) State v. Payne, 303 Conn. 538 , 544, 34 A.3d 370 (2012) ; State v. Davis, 286 Conn. 17 , 28, 942 A.2d 373 (2008). The party seeking to overturn a discretionary ruling thus has a "heavy burden...." State v. Ross, 230 Conn. 183 , 226, 646 A.2d 1318 (1994), cert. denied, 513 U.S. 1165 , 115 S.Ct. 1133 , 130 L.Ed.2d 1095 (1995). "[W]hen reviewing the action of a trial court under an abuse of discretion standard, we should read the record to support, rather than contradict, [the trial court's ruling]." (Internal quotation marks omitted.) State v. Lugo, 266 Conn. 674 , 692 n. 16, 835 A.2d 451 (2003) ; accord State v. Orr, 291 Conn. 642 , 667, 969 A.2d 750 (2009) ("[i]n determining whether there has been an abuse of discretion, the ultimate issue is whether the court could reasonably conclude as it did" [internal quotation marks omitted] ); State v. Skakel, 276 Conn. 633 , 724, 888 A.2d 985 ("[i]n determining whether there has been an abuse of discretion, every reasonable presumption should be made in favor of the correctness of the trial court's ruling, and *671 we will upset that ruling only for a manifest abuse of discretion" [internal quotation marks omitted] ), cert. denied, 549 U.S. 1030 , 127 S.Ct. 578 , 166 L.Ed.2d 428 (2006). "Our role as an appellate court is not to substitute our judgment for that of a trial court that has chosen one of many reasonable alternatives." (Internal quotation marks omitted.) State v. Day, 233 Conn. 813 , 842, 661 A.2d 539 (1995).

A defendant who moves for severance pursuant to Practice Book § 41-18 has the burden to show that severance is warranted. State v. Davis, supra, 286 Conn. at 28 , 942 A.2d 373 . I agree with the majority that severance may be warranted when the defendant wishes to testify in one **148 of the cases against him, but to remain silent in the other. See, e.g., State v. Schroff, 198 Conn. 405 , 409, 503 A.2d 167 (1986), citing Baker v. United States, 401 F.2d 958 , 977 (D.C.Cir. 1968), cert. denied, 400 U.S. 965 , 91 S.Ct. 367 , 27 L.Ed.2d 384 (1970). Nevertheless, the defendant's burden to obtain severance on this basis is high. A defendant seeking severance must do more than express a desire to testify in only one case. Baker v. United States, supra, at 977; see also United States v. Alexander, 135 F.3d 470 , 477 (7th Cir. 1998). Instead, he must make a " 'convincing showing' " that he has (1) important testimony to give concerning one case, and (2) a strong need to refrain from testifying in the other. Baker v. United States, supra, at 977; State v. Schroff, supra, at 409, 503 A.2d 167 . To establish that he has important testimony to give, the defendant must show that his intended testimony credibly relates to the charges against him and will not be wholly cumulative of testimony available from other sources. See, e.g., United States v. Alosa, 14 F.3d 693 , 695 (1st Cir. 1994) (no prejudice from joinder when defendant's intended testimony did not credibly account for his conduct); United States v. Valentine, 706 F.2d 282 , 291 (10th Cir. 1983) (defendant's intended evidence was cumulative); United States v. Outler, 659 F.2d 1306 , 1313 (5th Cir. 1981) (same). Conversely, to show a strong need to refrain from testifying, a defendant must show that he will suffer substantial prejudice as a result of his testifying, such as opening the door to impeachment evidence; he may not rest on an assertion that he wishes to leave the government to its proof. See, e.g., United States v. Jones, 530 F.3d 1292 , 1301 (10th Cir. 2008) ; United States v. Valentine, supra, at 291 .

Moreover, to perfect this claim and enable the trial court to properly evaluate prejudice, "it is essential that the defendant present enough information-regarding the nature of the testimony he wishes to give [in one **149 case] and his reasons for not wishing to testify on the other-to satisfy the court that the claim of prejudice is genuine and to enable it intelligently to weigh the considerations of economy and expedition in judicial administration against the defendant's interest in having a free choice with respect to testifying." (Internal quotation marks omitted.) State v. Schroff, supra, 198 Conn. at 409 , 503 A.2d 167 . A defendant must give "specific examples of the exculpatory testimony that the defendant would give." United States v. Alexander, supra, 135 F.3d at 477 ; see United States v. Balzano, 916 F.2d 1273 , 1283 (7th Cir. 1990) (no showing of prejudice when defendant "neglected to set forth any specific examples of the alleged exculpatory testimony he would have presented"). A "general statement" about the topics of the intended testimony is not enough. United States v. Alexander, supra, at 477 .

In the present case, the defendant twice moved for severance on the basis that the joining of the two informations for a single trial was interfering with his decision *672 about whether to testify. He first filed a motion for severance on this basis, dated May 20, 2010, after the state had finished the evidence in the bribery case, but before it began presenting its extortion case. The trial court denied his motion and the state proceeded with its extortion case. The defendant renewed his request for severance on this basis with a second motion dated June 9, 2010, after the state had completed its extortion case. The trial court denied this motion, as well. The majority addresses only the May 20 motion and concludes that the trial court was required to sever the cases at that time. I disagree with this conclusion.

In my view, the defendant did not provide sufficient specific information about his proposed testimony to properly perfect his May 20 motion for severance, and this lack of information prevented the trial court from meaningfully considering his claim of prejudice. In his **150 motion, he provided only general statements about topics of testimony he intended to give, and did not provide the trial court with any specific facts that he intended to establish with his testimony or how it might differ from testimony already presented. 2 For example, he represented to the court that he needed to explain the reasons for his false statements to Michael Sullivan, an inspector with the state Division of Criminal Justice in its public integrity unit, and why he delayed in paying his bill, but he did not tell the court anything about what those reasons were. In addition, the May 20 motion stated that the defendant wanted to testify about "[h]ow [the contractor] Carlos Costa became involved in the [d]efendant's home renovation project, details regarding when he first approached ... Costa and requested a bill, [and] the number of times that he personally followed up with Costa regarding his request...." See footnote 2 of this dissenting opinion. As the majority explains in its recitation of the facts, however, Costa had already testified about these details. If the defendant intended to give different testimony on these points, such that it would not be cumulative, he, as the party moving for severance, had the burden to demonstrate that to the trial court. The defendant, however, did not give any indication of whether or how he expected his testimony to differ from Costa's. **151 By not giving the trial court any specific details about his intended testimony, the defendant deprived the trial court of the opportunity to properly assess his claim of prejudice. The trial court could not evaluate the extent to which his intended testimony was credible, relevant, and not entirely cumulative of testimony already presented. See, e.g., United States v. Alexander, supra, 135 F.3d at 477 (explaining that "general assertions" about topics of intended testimony are "insufficient to establish prejudice" and fall short of " 'convincing showing' " that is required for trial court to assess defendant's claim and grant severance). Without any specific *673 examples of the defendant's intended testimony, the trial court was left to speculate as to the substance and import of the testimony he intended to give, preventing it from balancing the extent of any possible prejudice to the defendant against considerations of judicial economy. State v. Schroff, supra, 198 Conn. at 409 , 503 A.2d 167 . In addition, the lack of any detail also prevented the state from meaningfully responding to the defendant's claim of prejudice-it had no notice of what the defendant would actually testify to and so could not formulate arguments based on the content of the defendant's proposed testimony.

The defendant argues in his brief that he did not provide specifics of his testimony to avoid giving the state "a preview of his defense...." It is just these specifics, however, that our case law and case law from federal courts require to support a motion for severance on this basis. See State v. Schroff, supra, 198 Conn. at 409-10 , 503 A.2d 167 ; see also United States v. Alexander, supra, 135 F.3d at 477 (defendant's failure to provide examples of his intended testimony is fatal to his claim); see also State v. Lemay, 46 A.3d 1113 , 1121 (Me. 2012) (defendant's tactical decision to not provide details about his intended testimony to avoid revealing theory of his defense inhibits court's ability to assess prejudice).

**152 The defendant had the burden to produce sufficient detailed information to support his May 20, 2010 motion and thereby to persuade the trial court to grant it. Given the paucity of information presented by the defendant, it was hardly an abuse of discretion for the trial court to deny the May 20 motion to sever. It is not enough for an appellate panel to disagree with the trial court's exercise of discretion; the defendant must show that the trial court's exercise was unreasonable under the circumstances presented. I would conclude that the defendant did not meet that burden.

In addition, although not considered by the majority, I would further conclude that the trial court also properly denied the defendant's second motion for severance. The defendant renewed his request for severance in his June 9, 2010 motion, after the state had presented its evidence in both cases. This time, however, at the hearing on the motion, he provided the trial court with a detailed description of the testimony he intended to provide in the bribery case and reiterated the reasons he wished to remain silent in the extortion case. 3 For example, regarding the reasons he misled Sullivan about his payment of the home improvement bill, the defendant's counsel represented to the court, for the first time, that the defendant would "explain the lies that were made to [Sullivan] with [the city's corporation counsel] in the room, and he'll testify that he was embarrassed to reveal that he had not paid the bill to [Costa] with [corporation counsel] present in the room." The defendant's counsel then set forth, in extensive detail, the testimony the defendant intended to give on approximately eighteen topics pertaining to the bribery charge.

Importantly, the defendant also requested alternative relief, including a request that, if the court refused severance, **153 he be allowed to testify in the bribery case, but remain silent and be shielded from any cross-examination with regard to the extortion case. After hearing argument on that motion, the trial court found that the defendant had shown that he had important *674 testimony to give in the bribery case and strong reasons to refrain from testifying in the extortion case. Nevertheless, the court, exercising its discretion, refused to sever the cases. Significantly, however, the trial court did grant the defendant's alternative requested relief, and permitted him to testify about the bribery case without being subject to cross-examination with regards to the extortion case. The defendant, however, ultimately chose not to testify.

In determining whether the defendant should have new and separate trials on the charges he faces, it is of substantial import to me that the trial court granted him an alternative form of relief, one that he had expressly requested in his motion to sever -the right to testify on the bribery charges without being exposed to cross-examination on the extortion charges. Practice Book § 41-18 specifically authorizes the court to provide such other relief as "justice may require" in the alternative to severance. Although the defendant ultimately decided not to testify at all, in my view, the trial court's grant of alternative relief that he specifically requested substantially undercuts his claim of prejudice. The trial court's grant of the defendant's requested alternative relief afforded him protection from cross-examination on the extortion charge and thus mitigated to a significant extent any prejudice to the defendant caused by joinder. I recognize that this relief might not have provided complete protection from all prejudice that might have arisen if he took the stand to expressly deny one set of charges while remaining silent on the other. Nevertheless, under the circumstances of this case, I conclude that the defendant did not present a convincing **154 showing of substantial prejudice, especially in light of the deferential abuse of discretion standard that we must apply. State v. Davis, supra, 286 Conn. at 27-28 , 942 A.2d 373 .

For these reasons, in my view, the trial court properly denied the defendant's motions for severance. Consequently, I respectfully dissent and would reverse the Appellate Court's judgment and remand the case to that court to consider the defendant's remaining claims on appeal not previously addressed by that court.
