COMMISSIONER OF CORRECTION (SC 20222) Robinson, C. J., and Palmer, McDonald, D’Auria, Mullins, Kahn and Ecker, Js.* Syllabus In accordance with this court’s decision in State v. Salamon (287 Conn. 509), when a criminal defendant is charged with kidnapping in conjunc- tion with another underlying crime, such as robbery, the jury must be instructed that the defendant cannot be convicted of kidnapping if the restraint imposed on the victim was merely incidental to the commission of that underlying crime. The petitioner, who had been convicted of multiple counts of kidnapping in the first degree and robbery in the first degree in connection with armed robberies at two separate retail stores, sought a writ of habeas corpus, claiming that his due process right to a fair trial under the fifth and fourteenth amendments to the United States constitution was violated. In each armed robbery, after the petitioner obtained money from his victims, he forced them at gunpoint into the store’s bathroom and attempted to jam the bathroom door shut. The victims remained inside of the bathroom for only a few minutes, exiting once they believed that the petitioner left the store. Following this court’s determination that Salamon, which had been decided more than ten years after the petitioner’s trial, applied retroactively in habeas actions, the petitioner challenged his kidnapping convictions on the ground that the jury instructions at his criminal trial were not in accordance with the require- ments set forth in Salamon. The habeas court denied the petitioner’s habeas petition, concluding that the respondent, the Commissioner of Correction, had demonstrated that the absence of a Salamon instruction was harmless error. On the granting of certification, the petitioner appealed to the Appellate Court, which reversed the habeas court’s judgment. The Appellate Court concluded that a jury reasonably could have found that the petitioner’s movement and restraint of the victims were part of a continuous, uninterrupted course of conduct related to the robberies. The Appellate Court applied the harmless error standard set forth in Neder v. United States (527 U.S. 1) in determining that the absence of a Salamon instruction was not harmless beyond a reasonable doubt. On the granting of certification, the respondent appealed to this court. Held: 1. The standard articulated in Brecht v. Abrahamson (507 U.S. 619), which requires a new trial only if the instructional error had a substantial and injurious effect or influence in determining the jury’s verdict, applies to Salamon claims raised in habeas proceedings: contrary to the petition- er’s assertion that stare decisis required the application of the Neder standard, this court had not previously resolved the question of which standard applied to Salamon errors on collateral review; moreover, the Brecht standard provided the proper harmless error standard for Salamon errors in habeas actions, as it was consistent with the handling of other claims of error in habeas proceedings by both this court and the federal courts, a number of sister state courts had adopted that standard for the collateral review of constitutional errors, and it afforded a habeas petitioner significant protection, requiring a new trial unless the reviewing court has confidence that a properly instructed jury would have found the petitioner guilty beyond a reasonable doubt; furthermore, two of the principal rationales for applying a different harm standard (the Brecht standard) to constitutional errors in habeas actions than the harm standard applied to constitutional errors raised on direct appeal, namely, the finality of judgments and the extraordinary nature of the habeas remedy, applied equally to state and federal habeas proceedings, the United States Supreme Court previously had rejected the petitioner’s claim that the rule preventing a trial court from directing a guilty verdict prohibited a reviewing court from finding that a Salamon error was harmless when the evidence presented at trial compelled such a conclu- sion, the Brecht standard was not so vague as to be difficult to apply, and the application of the Brecht standard would not be unfair to the petitioner but, rather, would strike a balance between bestowing a wind- fall on the petitioner and penalizing him for failing to anticipate this court’s reinterpretation of this state’s kidnapping statutes. 2. The habeas court correctly determined that the trial court’s failure to instruct the jury at the petitioner’s criminal trial in accordance with Salamon was harmless because it did not give rise to a risk of prejudice sufficient to undermine confidence in the verdict, and, accordingly, the Appellate Court’s judgment was reversed: under Salamon, the jury, having found abduction, restraint, and the criminal intent associated therewith, necessarily had to find the petitioner guilty of kidnapping under the applicable statute (§ 53a-92 (a) (2) (B)) unless it found that the restraint and associated criminal intent were limited to that inherent in the robberies; moreover, even though the petitioner did not move his victims a great distance or restrain them for a long period of time, the jury could not reasonably have found that the asportation and restraint were limited to that which was necessary to carry out the robberies, as the actions occurred after the objective of each robbery had been completed, were conducted in order to make it more difficult for the victims to summon assistance and to reduce the petitioner’s risk of detection, and subjected the victims to unique risks and harms, both physical and psychological, beyond those inherent in the robberies them- selves.

Opinion PALMER, J. In this certified appeal and the compan- ion case decided herewith; see Bell v. Commissioner of Correction, 339 Conn. 79, A.3d (2021); we again revisit our decision in State v. Salamon, 287 Conn. 509, 949 A.2d 1092 (2008), in which we overruled our long-standing interpretation of this state’s kidnapping statutes and held that, when a criminal defendant is charged with kidnapping in conjunction with another underlying crime, such as rape or assault, the jury must be instructed that the defendant cannot be convicted of kidnapping if the restraint imposed on the victim was merely incidental to that underlying crime. See id., 542–50. We now must resolve two questions left open by Salamon and its progeny. First, when a petitioner seeking habeas relief establishes a Salamon error, does the habeas court assess the harm of that error according to the legal standard that the United States Supreme Court articulated in Brecht v. Abrahamson, 507 U.S. 619, 623, 113 S. Ct. 1710, 123 L. Ed. 2d 353 (1993) (new trial is mandated if instructional error ‘‘had [a] substan- tial and injurious effect or influence in determining the jury’s verdict’’ (internal quotation marks omitted)), or the more petitioner friendly standard that the high court adopted in Neder v. United States, 527 U.S. 1, 18, 119 S. Ct. 1827, 144 L. Ed. 2d 35 (1999) (new trial is required unless it is ‘‘clear beyond a reasonable doubt that a rational jury would have found the defendant guilty absent the [instructional] error’’)? Second, did the habeas court in the present case, in denying the habeas petition of the petitioner, Mark Banks, and ruling in favor of the respondent, the Commissioner of Correc- tion, correctly conclude, as a matter of law, that a Sala- mon error is harmless when a perpetrator forcibly removes his victims from the scene of a robbery after having taken their property and then restrains them in order to facilitate his escape? Or, in the alternative, did the Appellate Court, in reversing the judgment of the habeas court, correctly conclude that the petitioner was entitled to a new trial because a jury reasonably could have found that the petitioner’s postrobbery movement and restraint of his victims was merely incidental to the underlying crimes and bore no independent criminal significance? See Banks v. Commissioner of Correc- tion, 184 Conn. App. 101, 131–32, 194 A.3d 780 (2018). We conclude that the Brecht standard, which governs federal habeas actions, applies in state habeas proceed- ings as well.1 We further conclude that the habeas court correctly determined that the trial court’s failure to instruct the petitioner’s jury in accordance with Sala- mon was harmless. Accordingly, we reverse the judg- ment of the Appellate Court. I In 1995, the petitioner was arrested and charged in connection with the armed robberies of two Bedding Barn stores, the first in Newington and the second in Southington. The two cases were consolidated and tried jointly before a jury in October, 1997. The facts that the jury reasonably could have found with respect to both robberies are set forth by Judge (now Justice) Keller in her dissent from the opinion of the Appellate Court majority in the present case. See Banks v. Com- missioner of Correction, supra, 184 Conn. App. 140–43 (Keller, J., dissenting). ‘‘With respect to the earlier of the two robberies . . . Michael Kozlowski testified that he was working at the Newington Bedding Barn on August 30, 1995, at about 9 p.m. As Kozlowski prepared to close the store, the petitioner entered. Kozlowski testified that he approached the petitioner with the belief that the petitioner was a customer. When Kozlowski showed the petitioner a king-size bed, the petitioner said, ‘let me count my money,’ and reached into his bag and produced a gun. Kozlowski testified that the petitioner said, ‘[d]on’t try anything, I’ll bust you one, just walk over to the register.’ The petitioner then told him to get behind the counter and pointed his gun at Kozlowski’s chest. Kozlowski testified that, after the petitioner took the money from the cash register and a wallet from his coworker, Howard Silk, ‘[the petitioner] moved [Koz- lowski and Silk] . . . down to the hallway into the bathroom and . . . he then put [them] into the bath- room and put a mop handle or something behind the door.’ Kozlowski testified that the petitioner, as they walked down the hallway to the bathroom, said, ‘[d]on’t try anything; I’ll blow your head off . . . .’ Kozlowski indicated that, after the petitioner closed the bathroom door and locked Kozlowski and Silk in there, ‘[they] ducked down thinking he was going to shoot through the door because it was only a piece of plywood, basi- cally, and, [a] couple of minutes after, [they] heard a bell, which [was] on the front door, [and which rings whenever someone enters or leaves the store] . . . . [They] then . . . kicked the door, basically, and went downstairs.’ ‘‘Silk testified that he also was working at the Newing- ton Bedding Barn during the evening of August 30, 1995. Silk stated that, as he was in the process of closing the store, he noticed the petitioner following Kozlowski toward the counter. As the petitioner and Kozlowski approached, Silk realized that the petitioner was point- ing a gun at Kozlowski’s back. Silk testified that the petitioner told Kozlowski and Silk that he wanted the money, so Kozlowski took the money from the register as the petitioner pointed the gun at Silk’s chest. After Silk told the petitioner that there was no safe inside the store, the petitioner led Silk and Kozlowski toward the back of the store at gunpoint. Silk testified that he handed the petitioner the $17 in his wallet and then the petitioner ‘proceeded to put [them] into the bathroom area’ and attempted to jam the door with a mop handle. Silk testified that he believed that the petitioner put them in the bathroom so that he could escape and that, after less than two minutes [possibly less than one minute], he heard the bell ring that ‘goes off when [the door] opens and . . . [he] hoped that [the bell had rung] when [the petitioner] left.’ After waiting for thirty seconds after hearing the doorbell ring, Silk and Koz- lowski were easily able to open the bathroom door. Silk testified that they went downstairs into the basement of the building to the warehouse . . . to call 911 and wait for the police to arrive in the event that the peti- tioner was still on the first floor. ‘‘In the second case, Kelly Wright testified that she was working at the Southington Bedding Barn on Sep- tember 13, 1995. She recalled that, at 8:55 p.m., five minutes before the store was set to close, while Wright’s roommate, Idelle Feltman, was waiting in the store to take her home, the petitioner and an unidentified female entered the store. Wright testified that the petitioner and the female split up and appeared to be shopping for king-size beds. Wright testified that she was sitting behind the store counter when the petitioner arrived and that she rose in order to greet him because it was store policy to do so whenever a potential customer arrived. Before Wright could make it around the counter, however, the petitioner told her to get on the floor. Wright testified that she noticed that the peti- tioner had a gun in his hand and was holding it out parallel to the floor. The petitioner told Feltman to get the money from the register. Feltman gave the peti- tioner the money in the register in a bank bag. Wright testified that the petitioner then inquired if there was a basement in the store, and Feltman responded by telling the petitioner that there was no basement . . . but [that] there was a bathroom. Wright testified that the petitioner led her and Feltman to the bathroom at gunpoint and told them to enter the bathroom, lock the door, and ‘not to be a hero, let the cops do their jobs.’ Wright stated that she heard a buzzer go off, which indicated that the door to the store had been opened. She and Feltman waited for a ‘little bit,’ unlocked the door, and left the bathroom to call 911. Wright estimated that about five to six minutes elapsed between the time the petitioner entered the store [and] the time she and Wright were able to contact the police. ‘‘Feltman testified that she went to the Southington Bedding Barn to pick up Wright from work because the two planned to go out to dinner. During her testimony, she recalled that two people, the petitioner and a woman, entered the store right before closing and that the pair split up after they entered the store. Feltman testified that the petitioner approached the counter and removed a gun from his bag. He waved the gun and told her to give him the money in the register. Feltman emptied the register, which contained less than $100, and handed the money to the petitioner. Feltman testi- fied that, after he obtained the money, the petitioner inquired whether there was a basement in the store and that Feltman and Wright replied that there was no basement . . . but [that] there was a bathroom. Felt- man stated that the petitioner led her and Wright in a single-file line to the bathroom and then instructed them to enter, while aiming the gun at them and causing them to be scared. Feltman and Wright entered the bathroom and waited a minute or two after they heard the door buzzer that indicated someone had entered or left the store. At this point, the two left the bathroom and found a mattress that had been placed in the narrow hallway leading to the bathroom as a ‘barricade . . . .’ Feltman testified that she pushed it off to the side and ‘walked right through.’ ’’ (Footnote omitted.) Id. The following additional facts and procedural history also are relevant to the present appeal. At trial, the petitioner did not seriously contest that the charged crimes occurred as alleged. Rather, his primary defense was that the various victims had misidentified him as the perpetrator and that no evidence other than the victims’ eyewitness testimony linked him to the crimes. Therefore, the vast majority of defense counsel’s ques- tions during cross-examination pertained to the identity issue, although counsel did inquire whether the perpe- trator had physically pushed the victims toward the bathrooms, how far the bathrooms were situated from the cash registers where the robberies occurred, and the ease with which the victims exited the bathrooms. There was testimony that the bathroom in the Newing- ton store was located approximately twenty-four feet from the register. During closing arguments, the prosecutor acknowl- edged in his introduction that Connecticut’s definition of kidnapping was counterintuitive, and he argued that ‘‘what we have here is clearly kidnapping in the state of Connecticut.’’ His argument as to the alleged kidnap- ping focused entirely on the petitioner’s conduct after having completed the robberies: ‘‘[T]he use of the gun to herd the people into the back room, I’d argue to you, is that type of restraint. Obviously, they are not free to leave . . . even that particular area, the path [toward] the bathroom. They are . . . obviously not free to leave the building. They are not free to go call the police. They are restricted in their movements, again, and the intent of the [petitioner] or again since we are right now discussing what’s not in dispute, the intent of the person who committed this crime was to accomplish the commission of a felony, that is, this was part of the plan to allow him to escape from committing this robbery.’’ The prosecutor thus argued the case as if (1) it was undisputed that the perpetrator had forced the victims to enter and remain in the bathroom at gunpoint in order to facilitate his escape from the robbery scene, and (2) the kidnapping allegedly was predicated on the restraint of the victims only after the perpetrator had taken the money from the cash registers. In his closing argument, defense counsel conceded that the robberies took place as alleged, contesting only that the petitioner was the perpetrator. He also essen- tially agreed with the prosecutor that the underlying facts were not in dispute: ‘‘As [the prosecutor] pointed out to you, this case begins and ends with identification, and I have conceded essentially that to you.’’ Defense counsel also conceded that the conduct that the state had identified as kidnapping transpired after the robber- ies had occurred: ‘‘You and I, we don’t want to be on the other side of what we think might be a real, live gun with a person who appears to be robbing us and then asking us to go to a back room and saying, don’t be a hero.’’ (Emphasis added.) The jury found the petitioner guilty of four counts of kidnapping in the first degree in violation of General Statutes § 53a-92 (a) (2) (B),2 four counts of robbery in the first degree in violation of General Statutes § 53a- 134 (a) (4), and two counts of criminal possession of a pistol or revolver in violation of General Statutes (Rev. to 1995) § 53a-217c. The trial court rendered judgment in accordance with the jury verdict and sentenced the petitioner to a total effective sentence of twenty-five years incarceration consecutive to any sentence the petitioner was presently serving. The Appellate Court rejected the petitioner’s claims on appeal, and this court denied his petition for certification to appeal to this court. State v. Banks, 59 Conn. App. 112, 113–14, 755 A.2d 951, cert. denied, 254 Conn. 950, 762 A.2d 904 (2000). At no time on appeal did the petitioner challenge the propriety of the trial court’s jury instructions on kid- napping. Thereafter, in 2008, more than one decade after the petitioner’s trial, we decided Salamon, in which ‘‘we reconsidered our long-standing interpretation of our kidnapping statutes, General Statutes §§ 53a-91 through 53a-94a. . . . [In that case] [t]he defendant [Scott Sala- mon] had assaulted the victim at a train station late at night . . . and ultimately was charged with kidnapping in the second degree in violation of [General Statutes] § 53a-94, unlawful restraint in the first degree, and risk of injury to a child. . . . At trial, [Salamon] requested a jury instruction that, if the jury found that the restraint had been incidental to the assault, then the jury must [find him not guilty] of the charge of kidnapping. . . . [Consistent with established precedent of this court] [t]he trial court declined to give that instruction [and Salamon was convicted of second degree kidnapping in addition to the two other crimes]. . . . ‘‘[On appeal, Salamon requested that we reexamine] our long-standing interpretation of the kidnapping stat- utes to encompass even restraints that merely were incidental to and necessary for the commission of another substantive offense, such as robbery or sexual assault. . . . We [did so and] ultimately concluded that [o]ur legislature . . . intended to exclude from the scope of the more serious crime of kidnapping and its accompanying severe penalties those confinements or movements of a victim that are merely incidental to and necessary for the commission of another crime against that victim. Stated otherwise, to commit a kid- napping in conjunction with another crime, a defendant must intend to prevent the victim’s liberation for a longer period of time or to a greater degree than that which is necessary to commit the other crime. State v. Salamon, supra, 287 Conn. 542. ‘‘We explained in Salamon that a defendant may be convicted of both kidnapping and another substantive crime if, at any time prior to, during or after the commis- sion of that other crime, the victim is moved or confined in a way that had independent criminal significance, that is, the victim was restrained to an extent exceeding that which was necessary to accomplish or complete the other crime. Whether the movement or confinement of the victim is merely incidental to and necessary for another crime will depend on the particular facts and circumstances of each case. Consequently, when the evidence reasonably supports a finding that the restraint was not merely incidental to the commission of some other, separate crime, the ultimate factual determination must be made by the jury. For purposes of making that determination, the jury should be instructed to consider the various . . . factors [rele- vant thereto] . . . . Id., 547–48.’’ (Citations omitted; internal quotation marks omitted.) State v. Hampton, 293 Conn. 435, 459–60, 988 A.2d 167 (2009). Three years later, in Luurtsema v. Commissioner of Correction, 299 Conn. 740, 12 A.3d 817 (2011), we held that Salamon applies retroactively in habeas actions. See id., 751, 760 (plurality opinion). That is, an individ- ual, such as the petitioner in the present case, who was convicted before we decided Salamon can nevertheless bring a habeas action challenging his conviction on the ground that his or her jury was not properly instructed as to the meaning of the kidnapping statutes, as clarified in Salamon.3 Because, however, Luurtsema involved two ques- tions reserved by the habeas court for the advice of this court limited to the issue of retroactivity; see id., 743 (plurality opinion); we did not have occasion in that case to decide what harmless error standard applies to Salamon errors in the habeas context. Subsequently, in 2014, the petitioner in the present case filed the petition for a writ of habeas corpus that is the basis of this appeal. In his amended petition, the petitioner alleged a violation of his due process right to a fair trial under the fifth and fourteenth amendments to the United States constitution, challenging his four kidnap- ping convictions on the ground that the instructions given to the jury were not in accordance with Salamon. The habeas court denied the petition. The court con- cluded that the respondent had demonstrated that the absence of a Salamon instruction at the petitioner’s criminal trial was harmless error because the ‘‘move- ments and confinements [of the victims] were perpe- trated after the crimes of robbery were committed and [could not] conceivably be regarded as coincidental with or necessary to complete the substantive crimes of robbery. Depriving someone of their freedom of movement by imprisoning them in a bathroom subse- quent to acquiring their money, although convenient for the robber, is not inherent in the crime of robbery. It is crystal clear that the petitioner’s intent and purpose for locking up his robbery victims [were] to postpone their summoning of assistance and reporting of the crime to [the] police, thus facilitating the petitioner’s escape from the scene and delaying detection of his crime, identity, and/or whereabouts. Also, the petitioner extended the period of infliction of duress and distress for the victims by restraining them beyond the time of fulfillment of his quest, [that is, his] seizure of cash.’’ (Emphasis in original.) The habeas court granted the petitioner’s petition for certification to appeal, and a divided panel of the Appellate Court reversed. Banks v. Commissioner of Correction, supra, 184 Conn. App. 132. The Appellate Court majority, applying the Neder harmless error stan- dard, determined that the absence of a Salamon instruc- tion was not harmless beyond a reasonable doubt. Id., 104, 132; see id., 112–13 n.7. Specifically, the majority, applying the six factor test that we set forth in State v. Salamon, supra, 287 Conn. 548, concluded that three of the factors tipped in the petitioner’s favor; see Banks v. Commissioner of Correction, supra, 130; and that a jury reasonably could have found that his movement and restraint of the four victims were part of ‘‘a continu- ous, uninterrupted course of conduct related to the robberies . . . .’’ Id., 132. Judge Keller penned a dissenting opinion. See id., 132–50 (Keller J., dissenting). She argued that five of the six Salamon factors pointed in the respondent’s favor and that no reasonable jury could conclude that the petitioner’s forcing his victims into an isolated bath- room at gunpoint, after having taken their valuables and emptied the cash registers, was merely incidental to and necessary for the commission of the robberies. Id., 143–50 (Keller, J., dissenting). We granted the respondent’s petition for certification to appeal, limited to the following two issues: (1) ‘‘When a habeas petitioner claims that the criminal trial court erred by omitting jury instructions on the intent element of kidnapping pursuant to [Salamon], is harm measured in accordance with [Brecht] or [Neder]?’’ And (2) ‘‘[d]id the Appellate Court [correctly] conclude that the absence of a Salamon instruction at the petitioner’s criminal trial was not harmless error?’’ Banks v. Com- missioner of Correction, 330 Conn. 950, 197 A.3d 391 (2018). Additional facts will be set forth as necessary. II We begin by addressing the first certified question, that is, whether the Brecht standard or the Neder stan- dard applies to Salamon claims raised in habeas pro- ceedings. We agree with the respondent that the Brecht standard, as defined herein, is applicable. A Under Neder, which adopted the Chapman standard; see Chapman v. California, 386 U.S. 18, 24, 87 S. Ct. 824, 17 L. Ed. 2d 705 (1967); the state must demonstrate that a trial error was harmless beyond a reasonable doubt. See Neder v. United States, supra, 527 U.S. 15. In the context of a criminal conviction in which the trial court failed to instruct the jury on an element of the charged offense, the Neder standard often has been framed as also requiring that the element at issue have been uncontested at trial, and that the evidence tending to establish that element be overwhelming, before an error may be deemed harmless. See, e.g., State v. Vel- asco, 253 Conn. 210, 232, 751 A.2d 800 (2000). The fed- eral courts apply Neder to assess the harmlessness of most constitutional errors on direct review. See, e.g., Neder v. United States, supra, 7. By contrast, under Brecht, the harmlessness of consti- tutional errors is assessed according to whether the error ‘‘had [a] substantial and injurious effect or influ- ence in determining the jury’s verdict.’’ (Internal quota- tion marks omitted.) Brecht v. Abrahamson, supra, 507 U.S. 637. This standard originated as the Kotteakos test. See Kotteakos v. United States, 328 U.S. 750, 776, 66 S. Ct. 1239, 90 L. Ed. 1557 (1946). It has been adopted as the harmless error standard for nonconstitutional errors by the federal courts and, more recently, by this court in State v. Sawyer, 279 Conn. 331, 357, 904 A.2d 101 (2006), overruled on other grounds by State v. DeJesus, 288 Conn. 418, 953 A.2d 45 (2008). See State v. Sawyer, supra, 357 (nonconstitutional evidentiary error is harmless if ‘‘an appellate court has a fair assur- ance that the error did not substantially affect the ver- dict’’ (internal quotation marks omitted)). Brecht also is the standard by which the harmfulness of most consti- tutional errors is assessed in federal habeas actions. The Brecht standard reserves the remedy of a new trial for errors resulting in ‘‘ ‘actual prejudice,’ ’’ as dis- tinguished from errors giving rise to a mere possibility of harm. Brecht v. Abrahamson, supra, 507 U.S. 637. We previously have likened the substantial prejudice necessary for relief from nonconstitutional error to error that is sufficiently prejudicial ‘‘to undermine confi- dence in the fairness of the verdict.’’ (Internal quotation marks omitted.) State v. Sawyer, supra, 279 Conn. 353; see also id., 352–54 (citing cases in which this court has applied ‘‘undermine confidence’’ test for purposes of determining harmfulness of nonconstitutional error). Notably, this is the same showing—characterized as a showing of a reasonable probability of a different result—required for constitutional claims alleging inef- fective assistance of counsel under Strickland v. Wash- ington, 466 U.S. 668, 687, 104 S. Ct. 2052, 80 L. Ed. 2d 674 (1984), and the suppression of material, exculpatory evidence under Brady v. Maryland, 373 U.S. 83, 87, 83 S. Ct. 1194, 10 L. Ed. 2d 215 (1963). The United States Court of Appeals for the Second Circuit has explained that, when Brecht is applied to a trial error in which the jury is not properly instructed as to an essential element of the charged crime, the reviewing court must undertake a careful, de novo review of the entire record and order a new trial unless the court is persuaded ‘‘that a properly instructed, rational jury would have found the [required element of the crime proven] beyond a reasonable doubt.’’ Peck v. United States, 106 F.3d 450, 456–57 (2d Cir. 1997). Although some courts expressly place the burden of demonstrating harmlessness under Brecht on the state, the United States Supreme Court has expressed the view that it is ‘‘conceptually clearer’’ simply to place the onus on the reviewing court to determine whether an error substantially influenced the jury’s decision. O’Neal v. McAninch, 513 U.S. 432, 436, 115 S. Ct. 992, 130 L. Ed. 2d 947 (1995); see id., 436–37. We agree with the high court, however, that, when the reviewing court is in equipoise as to the question, the error must be deemed to have affected the verdict. See id., 435. For all intents and purposes, then, once a habeas petitioner has established a Salamon violation, the respondent bears the burden of demonstrating that the failure to instruct the jury in accordance with Salamon was harmless. B Although the petitioner argues that stare decisis requires us to apply Neder, in reality, this court never has resolved the question of whether Salamon errors should be assessed under Neder or Brecht on collateral review. Most of the Salamon cases that we have decided have reached us on direct review, where it is undisputed that Neder is the proper standard. Only twice have we had occasion to apply Salamon in the habeas context. In the first case, Luurtsema, as we noted, the issue reached us in the context of reserved questions from the habeas court regarding the retroactive applicability of Salamon. Luurtsema v. Commissioner of Correc- tion, supra, 299 Conn. 742 (plurality opinion). Accord- ingly, we did not have cause to address the harmless error issue. In dictum, however, we strongly suggested that Brecht—or at least something short of Neder— would be the appropriate legal standard. See id., 769–70 (plurality opinion). In Luurtsema, we explained why, in holding that Salamon applies retroactively on collateral review, we were not persuaded by the argument that ‘‘a finding of retroactivity would flood the court system with habeas petitioners seeking to overturn kidnapping convictions . . . .’’ (Internal quotation marks omitted.) Id., 769 (plurality opinion). We explained that, of those potential habeas cases that ‘‘fall within the ambit of Salamon . . . we expect that courts will be able to dispose summarily of many cases [when] it is suffi- ciently clear from the evidence presented at trial that the petitioner was guilty of kidnapping, as properly defined, [and] that any error arising from a failure to instruct the jury in accordance with the rule in Salamon was harmless.’’ (Footnote omitted.) Id., 769–70 (plural- ity opinion). The fact that we thought that many Sala- mon cases could be disposed of summarily on the ground of harmless error strongly suggests that we did not envision that such claims would be evaluated under the stringent Neder standard. The second case—the only one in which we had the opportunity to review a final judgment from a habeas action finding a Salamon violation—was Hinds v. Com- missioner of Correction, 321 Conn. 56, 136 A.3d 596 (2016). In that case, we expressly left open the question of whether Neder or Brecht applies to Salamon claims on collateral review. Specifically, after first having found that the Salamon error was not harmless beyond a reasonable doubt under Neder; id., 81; the majority in Hinds stated that ‘‘this court has not had the occasion to consider whether . . . a more stringent standard of harm should apply in collateral proceedings . . . . Brecht v. Abrahamson, supra, 507 U.S. 623 . . . .’’ Hinds v. Commissioner of Correction, supra, 81. We concluded, however, that ‘‘[w]e need not decide in [Hinds] whether to enter the fray by adopting the stan- dard in Brecht and the uncertainties that accompany it . . . because . . . the petitioner would prevail even under the more stringent standard . . . .’’ Id., 83. We then proceeded to explain at some length why the Sala- mon error in that case would qualify as harmful, even if we were to employ a standard more favorable to the respondent. See id., 83–94; see also Epps v. Commis- sioner of Correction, 323 Conn. 901, 150 A.3d 679 (2016) (granting certification to appeal to resolve question, ‘‘unresolved by Hinds,’’ of ‘‘[w]hether . . . in a collat- eral proceeding, [when] the petitioner claims that the trial court erred by omitting an element of the criminal charge in its final instructions to the jury . . . harm [is] measured in accordance with Brecht . . . or . . . Neder’’ (emphasis added)).4 Accordingly, we disagree with the petitioner’s contention that precedent compels us to apply Neder. If anything, our prior case law sug- gests the opposite. C We conclude that Brecht, as characterized herein, provides the proper harmless error standard in state habeas actions, at least with respect to Salamon errors. We reach this conclusion for at least the following three reasons. 1 First, evaluating Salamon claims according to the Brecht standard is more consistent with how we handle other claims of error in habeas actions. The parties disagree as to which harmlessness standard is more consistent with our broader habeas jurisprudence, with each contending that adoption of the other party’s pre- ferred standard would create a ‘‘ ‘confused patchwork’ ’’ or draw ‘‘arbitrary distinctions . . . .’’ Because harm- lessness standards vary depending on the stage of review and the type of error at issue, some appearance of arbitrariness, from some vantage point, is, perhaps, inevitable, regardless of which standard we adopt. See United States v. Dominguez Benitez, 542 U.S. 74, 86, 124 S. Ct. 2333, 159 L. Ed. 2d 157 (2004) (Scalia, J., concurring in the judgment) (‘‘[b]y my count, [the United States Supreme] Court has adopted no fewer than four assertedly different standards of probability relating to the assessment of whether the outcome of trial would have been different if [the] error had not occurred, or if omitted evidence had been included’’ (emphasis omitted)); Brecht v. Abrahamson, supra, 507 U.S. 649 (White, J., dissenting) (‘‘[o]ur habeas jurispru- dence is taking on the appearance of a confused patchwork’’). It bears noting, however, that the vast majority of habeas cases that we review are subject to harm- lessness or prejudice review under some standard that is more onerous, from the petitioner’s standpoint, than Chapman/Neder. For example, many habeas cases present Strickland or Brady claims that require the petitioner to establish a reasonable probability that, but for the error, the result of the proceeding would have been different. See, e.g., Michael T. v. Commis- sioner of Correction, 307 Conn. 84, 91–92, 52 A.3d 655 (2012). The primary context in which we have required a showing of harmlessness beyond a reasonable doubt in habeas cases is when the prosecution knowingly has relied on or failed to correct false testimony at trial. See, e.g., Adams v. Commissioner of Correction, 309 Conn. 359, 370–73, 71 A.3d 512 (2013). In those cases, we reasoned that a ‘‘strict standard of materiality is appropriate . . . not just because [the constitutional violations] involve prosecutorial [impropriety], but more importantly because they involve a corruption of the truth-seeking function of the trial process.’’ (Internal quotation marks omitted.) Id., 372. Neither of those rationales applies in the Salamon context, in which the state tried cases appropriately, according to our then established interpretation of the kidnapping statutes. The first concurrence ‘‘see[s] no need for this stan- dard to be ‘consistent with how we handle other claims of error in habeas actions.’ ’’ Instead, the first concur- rence contends that alleged Salamon errors are unique among habeas claims in that ‘‘[a] Salamon violation . . . is a determination that the state, in prosecuting a defendant, was unconstitutionally relieved of proving an essential element of the crime of kidnapping.’’ Although we are not bound by the federal courts in this regard, we find it noteworthy that they have roundly rejected the argument that we should carve out this particular category of constitutional error for review according to a different standard. In California v. Roy, 519 U.S. 2, 117 S. Ct. 337, 136 L. Ed. 2d 266 (1996), the United States Supreme Court confronted a scenario strikingly similar to that presented by our Salamon jurisprudence. One year after a California jury found the petitioner, Kenneth Roy, guilty of first degree murder on a theory of felony murder, the California Supreme Court clarified the state’s felony murder law, holding that a stricter instruction on the intent element was required than the one that had been given in Roy. See id., 3, citing People v. Beeman, 35 Cal. 3d 547, 561, 674 P.2d 1318, 199 Cal. Rptr. 60 (1984). The United States Supreme Court agreed with the lower courts that, in light of Beeman, Roy had been convicted on the basis of a ‘‘misdescription of an element of the crime . . . .’’ (Internal quotation marks omitted.) California v. Roy, supra, 5. Nevertheless, the high court held that, not only was such an error not a structural error that defies analysis by harmless error standards; id.; but, on collat- eral review, it was subject to harmless error analysis under the Brecht standard rather than the Neder stan- dard. See id., 5–6. Although Roy involved a federal collateral attack on a state conviction and, therefore, arguably was predi- cated in part on considerations of comity and federal- ism, its holding has been applied in habeas actions challenging federal convictions, where those concerns do not weigh in the balance. Peck v. United States, supra, 106 F.3d 450, a decision of the United States Court of Appeals for the Second Circuit, provides an excellent case in point. In Peck, as in Roy and Salamon, an intervening court decision—this time by the United States Supreme Court itself—meant that the habeas petitioner in that case had been found guilty by a jury that had not been properly instructed as to the intent element of the charged crime, namely, structuring cash transactions to evade bank reporting requirements in violation of various provisions of title 31 of the United States Code. Id., 451–53. The Court of Appeals, after reviewing its harmless error jurisprudence; id., 453–55; concluded that ‘‘Brecht sets forth the correct methodol- ogy for determining if an instructional error of the type present in Roy is harmless.’’ Id., 456. As we discussed, the court emphasized that Brecht requires the reviewing court to undertake a careful, de novo review of the entire record; see id., 456–57; and to order a new trial unless the court is able to conclude ‘‘that a properly instructed, rational jury would have found the [required element of the crime proven] beyond a reasonable doubt.’’ Id., 457. Although we are free to diverge from the federal courts in defining the legal standards that govern appellate review of claims raised in state habeas petitions, we find Roy and Peck to be persuasive authority. As the respondent has argued, it is a close question whether the failure to give a Salamon instruction even consti- tutes error, let alone reversible error, in a case such as this, in which the conduct on which the kidnapping convictions were predicated did not occur until after the underlying robberies had been completed. By con- trast, as the companion case demonstrates, the Brecht standard provides substantial protection and mandates a new trial when a reviewing court does not retain full confidence in the fairness of the conviction. See Bell v. Commissioner of Correction, supra, 339 Conn. 82, 83. Other types of constitutional errors likewise run the gamut, ranging from more minor, technical violations to serious deprivations of fundamental constitutional rights. We see no reason to add epicycle upon epicycle by carving out a special standard of review solely for one subset of habeas claims. 2 Second, a number of our sister states have followed the federal courts in adopting Brecht as the proper harmlessness standard for collateral review of constitu- tional errors. See, e.g., White v. State, 729 So. 2d 909, 915 (Fla. 1999); State v. Thomas, 750 So. 2d 1114, 1126 (La. App. 1999), writ denied, 795 So. 2d 1203 (La. 2001); Sanchez v. State, 272 Or. App. 226, 241 n.10, 355 P.3d 172, review denied, 358 Or. 449, 366 P.3d 719 (2015); Ex parte Fierro, 934 S.W.2d 370, 372 (Tex. Crim. App. 1996), cert. denied sub nom. Fierro v. Texas, 521 U.S. 1122, 117 S. Ct. 2517, 138 L. Ed. 2d 1019 (1997); see also Hittson v. Humphrey, Docket No. 5:01-CV-384 MTT, 2012 WL 5497808, *36 (M.D. Ga. November 13, 2012) (Georgia habeas court applied Brecht), rev’d in part on other grounds sub nom. Hittson v. GDCP War- den, 759 F.3d 1210 (11th Cir. 2014), cert. denied sub nom. Hittson v. Chatman, 576 U.S. 1028, 135 S. Ct. 2126, 192 L. Ed. 2d 887 (2015). We do not mean to suggest that Brecht is the prevailing approach among our sister states. A number of jurisdictions apply Neder on collateral as well as on direct review of constitutional errors. See, e.g., In re Martinez, 3 Cal. 5th 1216, 1224–25, 407 P.3d 1, 226 Cal. Rptr. 3d 315 (2017); Guam v. Ojeda, Docket No. CRA10-011, 2011 WL 6937376, *13 (Guam December 23, 2011); Hill v. State, 615 N.W.2d 135, 140–41 (N.D. 2000). Still, the fact that other states have adopted and successfully applied Brecht goes a long way toward addressing the potential counterarguments discussed hereinafter. 3 Third, and most important, insofar as Brecht requires that a new trial be granted due to the omission of a Salamon instruction unless, despite the omission, a reviewing court retains confidence in the fairness of the kidnapping conviction, the Brecht test affords a habeas petitioner significant protection. Indeed, under Brecht, a petitioner seeking a new trial because of such an omission is afforded no less protection than a peti- tioner who has established, under Strickland, that coun- sel’s performance fell below constitutional standards, or, under Brady, that the state failed to turn over excul- patory information. In fact, a petitioner who, upon establishing a Salamon violation, is entitled to applica- tion of the Brecht standard actually will receive more protection than a petitioner seeking relief under Strick- land or Brady because, as we have explained, the state bears the burden of disproving harm or prejudice. As in cases involving Strickland and Brady claims, if the appeals court, upon review of the petitioner’s collateral attack on his conviction, is satisfied that the error—in this case the omission of a Salamon instruction—does not call into question the fairness of that conviction, then it seems clear that a new trial is not constitutionally required. Consequently, for the foregoing reasons, we conclude that, when a habeas petitioner convicted of kidnapping has demonstrated that the jury was not properly instructed in accordance with Salamon, the state meets its burden of establishing harmlessness only if the reviewing court, following a thorough, de novo review of the record, has confidence that a properly instructed jury would have found the defendant guilty beyond a reasonable doubt. D Several additional counterarguments have been asserted as to why we should assess the harmlessness of Sala- mon errors under Neder, even in habeas actions. For the following reasons, we ultimately do not find those arguments to be persuasive. 1 First, the petitioner and the first concurrence argue that to adopt the Brecht standard would be inconsistent with the rationales that animated our decisions in Sala- mon and Luurtsema. In Brecht, the United States Supreme Court offered three principal rationales for why a different harm standard should govern constitu- tional error in habeas actions than on direct appeal: (1) the presumption of finality following direct review of a conviction and the practical challenges that the state faces in potentially having to retry a petitioner years or—as in this case—decades after a crime; see Brecht v. Abrahamson, supra, 507 U.S. 633; (2) the extraordinary nature of the habeas remedy, which should be granted only to those petitioners who have been ‘‘grievously wronged and for whom belated liberation is little enough compensation’’ (internal quotation marks omit- ted) id., 633–34; and (3) concerns of federalism and comity, which counsel that federal courts defer to state courts that already have fully reviewed a petitioner’s case and have found no reversible error. Id., 635; see also Fry v. Pliler, 551 U.S. 112, 117, 127 S. Ct. 2321, 168 L. Ed. 2d 16 (2007) (discussing ‘‘primary reasons’’ for Brecht decision). The petitioner argues that, as a general matter, the Brecht standard is not suitable for state habeas actions because the federalism and comity concerns on which Brecht was in part predicated do not apply when a state court is deciding a state habeas claim in the first instance. He further argues that Brecht is particularly ill-suited to the review of Salamon claims. He contends that, in Salamon and Luurtsema, we assumed that, although the finality of judgments is an important con- sideration, ‘‘the interests of finality must give way to the demands of liberty and a proper respect for the intent of the legislative branch.’’ Luurtsema v. Commis- sioner of Correction, supra, 299 Conn. 766 (plurality opinion). Accordingly, he posits, we already have decided that the finality considerations addressed in Brecht are trumped by other considerations in the unique Salamon context. The first concurrence echoes these points. This argument, while perhaps facially appealing, ulti- mately is unpersuasive. As we noted, two of the three principal rationales on which Brecht relied—the finality of judgments and the extraordinary nature of the habeas remedy—apply to state court habeas proceedings no less than to their federal counterparts. Moreover, subse- quent to Brecht, the United States Supreme Court has downplayed the importance of the federalism and com- ity considerations discussed in that decision. Most nota- bly, in Fry, the high court, resolving a split among the federal courts of appeals, held that Brecht is the proper standard for assessing harm in a federal habeas action, even when the state courts failed to recognize the con- stitutional error and did not review it for harmlessness under Neder. See Fry v. Pliler, supra, 551 U.S. 114, 121–22; see also Davis v. Ayala, 576 U.S. 257, 268, 135 S. Ct. 2187, 192 L. Ed. 2d 323 (2015) (‘‘[t]he Brecht standard reflects the view that a [s]tate is not to be put to th[e] arduous task [of retrying a defendant] based on mere speculation that the defendant was prejudiced by trial error; the court must find that the defendant was actually prejudiced by the error’’ (internal quota- tion marks omitted)); Calderon v. Coleman, 525 U.S. 141, 146, 119 S. Ct. 500, 142 L. Ed. 2d 521 (1998) (finality concerns on which Brecht was predicated were espe- cially compelling when seventeen years had passed since petitioner’s sentencing). Indeed, in the wake of Fry, courts and commentators have opined that the finality and habeas specific concerns were the high court’s principal rationales for adopting a less onerous harmless error standard in Brecht. See, e.g., Hittson v. GDCP Warden, supra, 759 F.3d 1276 (Carnes, C. J., concurring) (‘‘Nothing in Brecht implies, let alone clearly establishes, that state courts must apply [Neder] on collateral review. If anything, Brecht’s principal rationale—that ‘collateral review is different from direct review’ and that the ‘substantial and injurious effect’ standard is ‘better tailored to the nature and purpose of collateral review than the [Neder] stan- dard’—implies that state courts, like federal courts, are not bound to apply the [Neder] standard when conduct- ing collateral review. The . . . Fry decision took Brecht one step further away from [that] position . . . .’’); 7 W. LaFave et al., Criminal Procedure (4th Ed. 2015) § 28.9 (b), pp. 382, 398 (most federal courts of appeals apply Brecht in habeas actions challenging federal convictions, despite inapplicability of federal- ism and comity concerns); J. Sullivan, ‘‘Danforth, Retro- activity, and Federalism,’’ 61 Okla. L. Rev. 425, 497 (2008) (‘‘in Brecht . . . the [c]ourt recognized that competing interests, including finality, warrant applica- tion of a different standard for proof of harm in evaluat- ing claims of constitutional error asserted in federal habeas proceedings’’ (footnote omitted)). As we noted, a number of our sister state courts have adopted Brecht as the proper standard for assessing harmless error in state habeas actions, despite the inapplicability of the federalism and comity considerations discussed in that decision. We also reject the petitioner’s contention that our cases already have struck the balance against the state’s inter- ests in preserving the finality of convictions. His argu- ment confuses the existence of the right with the proper remedy for its violation. See United States v. Cappas, 29 F.3d 1187, 1193 (7th Cir. 1994) (‘‘the [Brecht] standard does not define the scope of underlying substantive constitutional rights . . . but is rather about what rem- edy is required [when] it is agreed that constitutional rights have been violated’’ (emphasis omitted)). In Sala- mon, we explained why our prior cases had not accu- rately construed Connecticut’s kidnapping laws and how, upon a closer examination, it was clear that the legislature did not intend to criminalize as kidnapping conduct that was merely incidental to the commission of another crime, that is, conduct with no real indepen- dent criminal significance separate and apart from the underlying crime. See State v. Salamon, supra, 287 Conn. 542. In Luurtsema, we further explained why due process does not permit the continued incarceration of someone who has been convicted of a crime that he or she did not commit, as properly defined. See Luurt- sema v. Commissioner of Correction, supra, 299 Conn. 758–59 (plurality opinion). In that case, however, we also made clear that a habeas petitioner may not prevail on a Salamon claim when ‘‘continued incarceration would not represent a gross miscarriage of justice, such as [when] it is clear that the legislature did intend to criminalize the conduct at issue, if perhaps not under the precise label charged. In situations [in which] the criminal justice system has relied on a prior interpreta- tion of the law so that providing retroactive relief would give the petitioner an undeserved windfall, the tradi- tional rationales underling the writ of habeas corpus may not favor full retroactivity. See Guzman v. Greene, [425 F. Supp. 2d 298, 315 (E.D.N.Y. 2006), aff’d 337 Fed. Appx. 27 (2d Cir. 2009)] (‘it is certainly not unjust, let alone manifestly unjust, to keep a murderer in jail’).’’ Luurtsema v. Commissioner of Correction, supra, 764 (plurality opinion). As we noted, we further emphasized in Luurtsema that reviewing courts will be able to sum- marily dispose of many Salamon errors as harmless. Id., 769–70 (plurality opinion). Accordingly, although we certainly have not treated finality as the be all and end all, we also have never said that the mere fact that a petitioner was found guilty of kidnapping by an improperly instructed jury necessarily amounts to reversible error. 2 A related argument advanced by the petitioner is that for us to apply Brecht in the present case, and to find the errors harmless because we conclude that the evidence presented at trial supports a kidnapping conviction under the proper definition of that crime, would be tantamount to directing a verdict for the state. The United States Supreme Court has expressly rejected this argument. Only a small share of constitutional errors are struc- tural, that is, so presumptively harmful that they require automatic reversal. See, e.g., Washington v. Recuenco, 548 U.S. 212, 218, 126 S. Ct. 2546, 165 L. Ed. 2d 466 (2006). Most, rather, are subject to harmless error review. See, e.g., id. (‘‘We have repeatedly recognized that the commission of a constitutional error at trial alone does not entitle a defendant to automatic reversal. Instead, most constitutional errors can be harmless.’’ (Internal quotation marks omitted.)). This includes errors in instructing the jury as to the elements of a crime. We have said this not only in Luurtsema and other Salamon cases, but also in numerous other con- texts. See, e.g., State v. Thompson, 305 Conn. 806, 817– 18, 48 A.3d 640 (2012) (erroneous instruction concern- ing circumstances under which jury properly could aggregate value of stolen property for purpose of determining whether state had proven element of offense of first degree larceny requiring theft of prop- erty worth more than $10,000); Small v. Commissioner of Correction, 286 Conn. 707, 726–29, 946 A.2d 1203 (court improperly failed to instruct jury on definition of ‘‘attempt,’’ even though petitioner was charged with felony murder predicated on, inter alia, attempted rob- bery), cert. denied sub nom. Small v. Lantz, 555 U.S. 975, 129 S. Ct. 481, 172 L. Ed. 2d 336 (2008); State v. McDonough, 205 Conn. 352, 354–62, 533 A.2d 857 (1987) (erroneous instruction concerning inferences jury rea- sonably might draw from circumstantial evidence), cert. denied, 485 U.S. 906, 108 S. Ct. 1079, 99 L. Ed. 2d 238 (1988). Indeed, Neder itself stands for the proposition that the omission of a single element of a crime from the jury charge is not a structural constitutional error that is exempt from harmless error analysis. Washing- ton v. Recuenco, supra, 218–19; Lanier v. United States, 220 F.3d 833, 838 (7th Cir.), cert. denied, 531 U.S. 930, 121 S. Ct. 312, 148 L. Ed. 2d 250 (2000). Accordingly, the well established rule that a trial court may not direct a verdict of guilty in a criminal trial; State v. Ubaldi, 190 Conn. 559, 573, 462 A.2d 1001, cert. denied, 464 U.S. 916, 104 S. Ct. 280, 78 L. Ed. 2d 259 (1983); see General Statutes § 54-89; in no way implies that a reviewing court cannot adjudge a Salamon error harm- less when the evidence presented at trial, assessed under the appropriate legal standard, compels such a conclusion. See Washington v. Recuenco, supra, 220–22 (rejecting argument that subjecting trial court’s failure to submit sentencing factor to jury to harmless error analysis amounted to improper directed verdict of guilty); Neder v. United States, supra, 527 U.S. 17–19 (same, with respect to failure to properly instruct jury as to elements of crime charged). 3 The petitioner’s next argument against adopting Brecht as the standard for assessing the harmlessness of Salamon errors on habeas review is that the Brecht standard is vague and not easily applied. Most of the cases on which the petitioner relies for this proposition, however, were decided in the mid-1990s, in the immedi- ate aftermath of the Brecht decision. Since that time, the United States Supreme Court has provided additional guidance, clarifying several of the key ambiguities left open in Brecht itself.5 See, e.g., O’Neal v. McAninch, supra, 513 U.S. 435–37 (resolving burden of proof ques- tions); see also Fry v. Pliler, supra, 551 U.S. 121–22 (clarifying that Brecht applies on federal habeas review, regardless of whether state courts recognized error and reviewed it for harmlessness beyond reasonable doubt). Perhaps most significant, the Brecht test, as character- ized herein, is the same familiar standard—namely, whether the error undermines confidence in the convic- tion—used for ascertaining prejudice under Strickland and Brady, a standard that we are called on to apply regularly. We do not expect that it will be unduly diffi- cult to apply that standard in ascertaining the harm caused by an omitted Salamon instruction when that task is undertaken with due regard for the broader context of our holding in Salamon, that is, to ensure that a defendant is not convicted of kidnapping unless the conduct at issue has criminal significance indepen- dent of the underlying offense. 4 Finally, the first concurrence asserts that to apply Brecht in the present case would be unfair to the peti- tioner and to others similarly situated. That this court opted to revisit and revise our interpretation of the state’s kidnapping laws following his conviction is no more the fault of the petitioner than of the state. Although would-be offenders were on notice in 1995 that they could be charged with kidnapping solely on the basis of the restraint inherent in robberies or assaults, they, like the state, did not have any reason to try their cases with the Salamon distinction in mind. Moreover, it may seem discrepant to assess the impact of the instructional error according to the more forgiv- ing Brecht standard when, if we had decided Salamon one decade earlier, while the petitioner’s direct appeal was pending, the state would have borne the burden of proving that the error was harmless beyond a reason- able doubt. As we discussed, the somewhat scattershot nature of harmless error jurisprudence, with standards varying by the type of error at issue, the stage of review, and the jurisdiction in which the claim is reviewed, means that whichever standard we apply to Salamon errors in state habeas cases may appear to be unfair or incon- gruous from one vantage point or another. It certainly will not seem unjust from the respondent’s standpoint to require a showing that there is some reasonable likelihood that the failure to give the jury a Salamon instruction had a substantial and injurious effect or influence on the outcome before requiring the state to retry the petitioner for crimes that were committed more than twenty-five years ago. If the ultimate question is how to allocate the risk that an appellate court will revise its interpretation of a criminal statute such as § 53a-92 after a conviction has been obtained and affirmed on direct appeal, we think that the fairest and most reasonable approach is to adopt the Brecht stan- dard, as defined herein, to tip the balance in favor of the petitioner in close cases, and to evaluate the facts of a particular case with an eye toward whether there is a reasonable likelihood that the petitioner could and would have presented a different and potentially suc- cessful defense with the benefit of Salamon’s guidance. This avoids bestowing a windfall on the petitioner but also does not penalize him for failing to anticipate our reinterpretation of the kidnapping statute.6 III A Having concluded that the harm associated with depriving the petitioner of a Salamon instruction should be assessed under the Brecht standard, we turn now to the second question in this appeal: whether the largely undisputed facts that were presented at trial and cred- ited by the jury satisfy the statutory definition of kidnap- ping, as clarified by this court, such that we are confident that a properly instructed jury would have found the petitioner guilty of kidnapping beyond a rea- sonable doubt notwithstanding the Salamon error. We note at the outset that the question of whether conduct bears independent criminal significance as kid- napping is one of law. It is, of course, the function of the jury to find the relevant facts, including, ultimately, whether a crime was committed with the intent neces- sary to qualify as kidnapping, namely, the specific intent to prevent the victim’s liberation and not simply to perpetrate the underlying crime. See State v. Salamon, supra, 287 Conn. 532, 547–48. At the same time, it is beyond cavil that it is the role of the judiciary to inter- pret the relevant statutes and to define, as a matter of law, what type of conduct constitutes kidnapping according to those statutes. See id., 529. As we explained in Salamon, a necessary corollary is that it falls to the courts to define the intent element of the crime of kidnapping; see id., 534–35; to delineate the ways in which kidnapping differs from coterminous crimes such as robbery and sexual assault; see id., 542; and to specify the factors that are relevant to that analy- sis; see id., 548; in light of our understanding of the legislative history of the kidnapping statutes and the policy objectives that animated their modern revision. See id., 542, 546. As we explain more fully hereinafter; see part III B of this opinion; our prior cases addressed the Salamon issue and defined the relevant factors in the context of the restraint involved in an ongoing sexual and/or physical assault. We now confront a distinct and novel scenario—asportation and confinement to facilitate a perpetrator’s escape following the completion of a rob- bery—in which we have not previously had cause to apply Salamon, and in which a different provision of the kidnapping statutes is at issue. Although it always will be for the jury to find the relevant facts and to determine whether the perpetrator had the requisite criminal intent, it falls to this court to define in the first instance how that criminal intent differs from the intent necessary to commit an underlying crime for this cate- gory of offenses, as well as how the factors that we have articulated and applied to assess harmless error in the sexual assault context operate in this novel arena. As we explained in Salamon, those questions ultimately are ones of legislative intent, framed by the history and policy rationales that animate the relevant statutes. See id., 529, 542. B We next consider the standards by which a reviewing court is to assess the harmfulness of a Salamon error in the context of a robbery in which the perpetrator moves and confines the victims after having forcibly taken valuables in their possession. For the reasons that follow, we are not persuaded by the reasoning of the Appellate Court majority, which concluded that a jury reasonably might find that the restraint and aspor- tation involved in the present case were undertaken as part of ongoing robberies and, therefore, that the petitioner might not have intended to restrain the vic- tims more than was necessary to carry out those robber- ies. See Banks v. Commissioner of Correction, supra, 184 Conn. App. 124–25, 131–32. 1 First, there is the matter of the statute at issue. In Salamon, the defendant was convicted of violating § 53a-94 (a), which provides that ‘‘[a] person is guilty of kidnapping in the second degree when he abducts another person.’’ See also State v. Salamon, supra, 287 Conn. 529–30 (explaining distinction between kidnap- ping, which requires abduction, and lesser offense of unlawful restraint, which merely requires restraint). Most of our subsequent Salamon cases have involved violations of that statute; e.g., State v. Fields, 302 Conn. 236, 238, 24 A.3d 1243 (2011); or of § 53a-92 (a) (2) (A), which provides that ‘‘[a] person is guilty of kidnapping in the first degree when he abducts another person and . . . he restrains the person abducted with intent to . . . inflict physical injury upon him or violate or abuse him sexually . . . .’’ E.g., Hinds v. Commissioner of Correction, supra, 321 Conn. 59; State v. Ward, 306 Conn. 718, 721, 51 A.3d 970 (2012); State v. Hampton, supra, 293 Conn. 437–38; State v. DeJesus, supra, 288 Conn. 420. All of those cases involved allegations that the alleged kidnapping was intertwined with a sexual or physical assault. The present case, by contrast, requires that we con- strue General Statutes § 53a-92 (a) (2) (B), which pro- vides that ‘‘[a] person is guilty of kidnapping in the first degree when he abducts another person and . . . he restrains the person abducted with intent to . . . accomplish or advance the commission of a felony . . . .’’7 As we concluded in Salamon with respect to the underlying crime of assault; see State v. Salamon, supra, 287 Conn. 542; it is clear that the legislature did not intend to criminalize as kidnapping unlawful restraint that is no greater than necessary for, and involves no wrongful intent other than that inherent in, the comple- tion of a robbery. It is equally clear, however, that the legislature, in adopting § 53a-92 (a) (2) (B), did intend that additional, gratuitous restraint used to accomplish or advance the commission of a robbery carry the added penalties associated with kidnapping. In other words, the mere fact that a perpetrator restrains a victim during the course of and in the service of a robbery does not mean that, under Salamon, the conduct does not constitute kidnapping. To so hold—or to permit a jury to so reason—would be to render § 53a-92 (a) (2) (B) a nullity, insofar as that statute criminalizes only such kidnappings. See State v. Buggs, 219 Kan. 203, 214, 547 P.2d 720 (1976) (construing similar Kansas statute). Accordingly, we are not persuaded by the reasoning of the Appellate Court majority that a jury reasonably might find that the petitioner’s conduct was not kidnap- ping merely because it occurred as part of the course of events of the robberies. See Banks v. Commissioner of Correction, supra, 184 Conn. App. 124–25, 131–32. As Judge Keller explained in her dissent and Judge Lavine in his dissent in the companion case, that is not the relevant legal inquiry. See id., 133 n.1, 145 n.6 (Keller, J., dissenting); see also Bell v. Commissioner of Correc- tion, 184 Conn. App. 150, 183 n.5, 194 A.3d 809 (2018) (Lavine, J., dissenting), aff’d, 339 Conn. 79, A.3d (2021). Rather, under Salamon, a jury, having found abduction, restraint, and the criminal intent associated therewith in the furtherance of a robbery, will necessar- ily find the petitioner guilty of kidnapping under § 53a- 92 (a) (2) (B) unless it also finds that the restraint, and the associated criminal intent, was limited to that inherent in the robbery itself. As we explain in the discussion that follows, when the question for the jury is properly framed in that manner, only one answer is reasonably possible in view of the facts of the pres- ent case. We find Virgin Islands v. Ventura, 775 F.2d 92 (3d Cir. 1985), to be instructive in this regard. In that case, the United States Court of Appeals for the Third Circuit construed a territorial statute that provided that ‘‘[w]ho- ever abducts, takes or carries away any person by force or threat with the intent to commit rape is guilty of kidnapping . . . .’’ Id., 96, quoting Act of June 30, 1983, No. 4838, 1983 V.I. Sess. Laws 100, 101 (codified at V.I. Code Ann. tit. 14, § 1052 (b)). As has this court; see, e.g., State v. Salamon, supra, 287 Conn. 548; the Third Circuit, in Virgin Islands v. Berry, 604 F.2d 221, 227 (3d. Cir. 1979), previously had applied a multifactor test to assess when, as a general matter, an alleged kidnapping committed in conjunction with another crime constitutes a discrete offense. In Ventura, how- ever, the Third Circuit held that the fact that the legisla- ture chose to specifically criminalize asportation incident to rape after Berry was decided meant that, with respect to cases falling under the new statute, certain factors of the test were necessarily satisfied and need not be considered on a case-by-case basis. See Virgin Islands v. Ventura, supra, 97 (‘‘[t]o apply the Berry factor [at issue in Ventura] would effectively override the will of the Virgin Islands legislature’’). Like- wise, in the present case, to instruct a jury that it could find that there was no kidnapping merely because the restraint occurred in the course of an ongoing robbery would effectively override the will of our state’s legisla- ture, which was to impose heightened penalties for precisely such conduct. 2 Second, the decision of the Appellate Court in this case not only runs afoul of the statutory language, but also fails to take due account of the particular factual scenario presented by this case. This case is categori- cally distinct from all of our prior Salamon cases insofar as the petitioner indisputably had accomplished the criminal objective of his underlying crimes prior to the commencement of the alleged kidnapping. Under such circumstances, there simply is no concern that the intent of the legislature will be frustrated by prosecuting a defendant for kidnapping solely on the basis of the restraint inherent in or necessary to accomplish the underlying crime. Many if not most robbers choose to leave the scene immediately upon obtaining the fruits of their crime. Numerous sister state courts have con- cluded, as a matter of law, that a perpetrator’s choice to remain at the crime scene and further restrict a victim’s liberty after having robbed him or her manifests independent, criminal significance. See, e.g., Black v. State, 630 So. 2d 609, 619 (Fla. App. 1993) (when restraint and removal occurred after perpetrator had taken money from store, court deemed it ‘‘obvious that the movement and confinement . . . [were] not inher- ent in the nature of the robbery . . . [but] had some significance independent of the robbery’’ (internal quo- tation marks omitted)), review denied, 639 So. 2d 976 (Fla. 1994); State v. Blouvet, 965 S.W.2d 489, 492 (Tenn. Crim. App. 1997) (‘‘[h]olding [the victim] at gunpoint and moving her about the store [are] certainly not inci- dental to the already accomplished felony of aggravated robbery’’); State v. Allen, 94 Wn. 2d 860, 864, 621 P.2d 143 (1980) (concluding that brief abduction that occurred after robbery to facilitate perpetrators’ flight from scene was ‘‘a wholly separate event’’ and not inci- dental to robbery because ‘‘[n]either the flight from the scene of the robbery nor the means of flight therefrom [were] statutorily or logically . . . part of [the] rob- bery’’), overruled on other grounds by State v. Vladovic, 99 Wn. 2d 413, 662 P.2d 853 (1983); see also State v. Golder, 127 Conn. App. 181, 190–91, 14 A.3d 399 (when defendant moved victim to different room and restrained her therein to facilitate his escape after tak- ing her jewelry, restraint bore independent criminal significance from completed burglary), cert. denied, 301 Conn. 912, 19 A.3d 180 (2011); People v. Bautista, 147 App. Div. 3d 1214, 1218, 47 N.Y.S.3d 503 (2017) (‘‘a kidnapping is generally deemed to merge with another offense . . . [when] there is minimal asportation immediately preceding the other crime or [when] the restraint and underlying crime are essentially simulta- neous’’ (internal quotation marks omitted)). Although we have not yet had occasion to expressly state this proposition, we implied it in two prior cases. In State v. Fields, supra, 302 Conn. 236, we addressed the state’s contention that the defendant was not enti- tled to a new trial on the challenged kidnapping count because the alleged kidnapping did not occur until after the assault of the victim had been completed. See id., 251. We indicated that ‘‘[w]e might agree with this con- tention’’ had the factual premises for the state’s argu- ment not been in dispute. Id. Subsequently, in Hinds v. Commissioner of Correction, supra, 321 Conn. 56, we distinguished certain cases from other jurisdictions that held the lack of a Salamon-type instruction to be harmless error because those cases involved ‘‘contin- ued restraint after completion of the nonkidnapping offenses . . . .’’ Id., 87. This makes sense. There is nothing specific to—let alone inherent in—the crime of robbery about forcing someone at gunpoint to the back of a store and restraining them in a bathroom or cooler. That conduct could just as well follow, and facilitate the offender’s escape from, a physical or sexual assault, or other crime. The purpose is to escape unhindered from a crime scene—which, presumably, is a goal of most crim- inals—and the specific nature of the underlying crime is simply irrelevant. 3 The Appellate Court majority rejected the respon- dent’s argument—and the conclusion of the habeas court—that the petitioner’s asportation and restraint of his victims necessarily bore independent criminal significance because they did not commence until after the petitioner had accomplished his primary goal of obtaining wrongful possession of the cash in the store registers. See Banks v. Commissioner of Correction, supra, 184 Conn. App. 114, 120. The majority reasoned that, according to some authorities, a robbery is not necessarily completed at the time that a perpetrator obtains unlawful possession of a victim’s property and, therefore, that force exercised after the petitioner had taken the victims’ money reasonably could be consid- ered to be incidental to the robberies. See id., 120–28. Judge Keller responded, and we agree, that we need not engage in an ‘‘unduly legalistic’’ analysis of the pre- cise moment at which a robbery ends. Id., 148 (Keller, J., dissenting). Regardless of whether the robberies can be said to have been ongoing in some sense, even after the petitioner took possession of the victims’ money, the important point for present purposes is that any movement and confinement imposed after that time served a fundamentally different objective. Whether this category of restraints implicates the concerns that we addressed in Salamon and, more broadly, whether they are of the type that the legislature intended to independently criminalize are questions of law that fall to this court to resolve. C Both the Appellate Court majority, in concluding that the Salamon error in the present case prejudiced the petitioner, and Judge Keller, in maintaining that it did not, contended that the six Salamon factors, on bal- ance, tipped in favor of their positions. Id., 115–30; id., 143–50 (Keller, J., dissenting). Those factors are (1) the nature and duration of the victim’s movement or confinement, (2) whether that movement or confine- ment occurred during the commission of the separate offense, (3) whether the restraint was inherent in the nature of the separate offense, (4) whether the restraint prevented the victim from summoning assistance, (5) whether the restraint reduced the perpetrator’s risk of detection, and (6) whether the restraint created a significant danger or increased the victim’s risk of harm independent of that posed by the separate offense. State v. Salamon, supra, 287 Conn. 548. We agree with Judge Keller that, in cases such as this, in which it is undis- puted that the perpetrator unlawfully restrained his vic- tims following, and to facilitate his escape from the location of, a robbery, the Salamon factors typically will tip against the petitioner’s claim. But see footnote 14 of this opinion. There is little dispute that the first Salamon factor— the extent of the victims’ asportation and confine- ment—tends to favor the petitioner in the present case, as will often be true in cases of this ilk. See Banks v. Commissioner of Correction, supra, 184 Conn. App. 115–20 (comparing cases in which this court and Appel- late Court concluded that conduct did, or did not, as matter of law, have independent criminal significance). That is to say, a jury reasonably could conclude that moving robbery victims fewer than ten yards and con- fining them for, at most, a few minutes during a perpe- trator’s escape from the crime scene does not, simply by virtue of the times and distances involved, bear inde- pendent criminal significance. In the preceding discussion, we explained why the second and third Salamon factors ordinarily will tip against the petitioner in a postrobbery kidnapping sce- nario. The conduct at issue occurred after the objective of the robbery had been completed. Nor was it inherent in the crime of robbery, insofar as many, if not most, robberies end with the perpetrator’s simply fleeing the premises rather than moving and confining the victims. In the discussion that follows, we explain why the final three Salamon factors also favor the respondent in such situations. 1 The parties, and the Appellate Court majorities and dissents, in both this case and the companion case, Bell, disagree as to how the Salamon factors are to be balanced and whether any of the six factors is disposi- tive. Although the relative importance of the various factors will vary depending on the context, we have made clear that the touchstone in any Salamon case, in assessing whether conduct associated with a rape, robbery, or assault has independent criminal signifi- cance as a kidnapping, is the intent of the offender. See State v. Salamon, supra, 287 Conn. 532 (‘‘the proper inquiry for a jury evaluating a kidnapping charge is not whether the confinement or movement of the victim was minimal or incidental to another offense against the victim but, rather, whether it was accomplished with the requisite intent, that is, to prevent the victim’s liberation’’); id., 534 (intent element is what defines abduction, the sine qua non of kidnapping); id., 542 (‘‘to commit a kidnapping in conjunction with another crime, a defendant must intend to prevent the victim’s liberation’’). We have continued to emphasize this point in our subsequent Salamon cases. See, e.g., Hinds v. Commissioner of Correction, supra, 321 Conn. 90 (‘‘the ultimate question [is] the perpetrator’s intent in taking these actions’’ (emphasis in original)); State v. Fields, supra, 302 Conn. 247 (referring to Salamon instruction as ‘‘incidental intent instruction’’); State v. Winot, 294 Conn. 753, 762, 988 A.2d 188 (2010) (‘‘we repeatedly [have] explained [that] the touchstone for determining whether the movement or confinement at issue consti- tuted kidnapping was not its extensiveness, but rather, whether it was accomplished with the requisite intent’’ (internal quotation marks omitted)). The fourth and fifth Salamon factors—whether the restraint prevented the victim from summoning assistance or reduced the perpetrator’s risk of detection—must be understood in that light. In a scenario such as this, in which the perpetrator removes the victims from the scene of the robbery and restrains them after having forcibly taken their prop- erty, we agree with the respondent that the fourth and fifth Salamon factors are the ones that speak most directly to the intent of the perpetrator. The goal of a robbery is to take possession of another’s property. Once that property has been taken by force, the purpose of leading the victims to a different, more isolated loca- tion and requiring that they remain there for some period of time is, undoubtedly, to facilitate the offend- er’s escape from the premises, undetected and unob- structed. The Kansas Supreme Court put the point most succinctly: ‘‘The forced direction of a store clerk to cross the store to open a cash register is not a kidnap- ping; locking him in a cooler to facilitate escape is.’’ State v. Buggs, supra, 219 Kan. 216. Indeed, sister state courts have found it apparent that restraining robbery victims after having taken their property bespeaks an independent criminal intention to facilitate escape with- out detection or apprehension. See, e.g., Miles v. State, 839 So. 2d 814, 820 (Fla. App. 2003). Nothing in the record of the present case suggests that a different result is warranted. Silk provided the only direct evidence regarding the petitioner’s rationale for forcing his victims into the bathrooms after robbing them. In response to the question ‘‘what was the pur- pose in your going into the bathroom,’’ Silk answered: ‘‘I would say just so he could get away.’’8 The petitioner has not been able to articulate any other plausible ratio- nale for his postrobbery treatment of the victims other than to facilitate his escape, and none is apparent.9 In cases involving strikingly similar fact patterns, sister state courts have had no difficulty concluding that the purpose for secreting and restraining robbery victims after taking their property is to facilitate the perpetra- tor’s escape. See, e.g., Ferguson v. State, 533 So. 2d 763, 764 (Fla. 1988) (forced confinement of restaurant employees in restroom after robbery was ‘‘intended to make it more difficult for the victims to identify the perpetrator and immediately call for help’’); Richardson v. State, 875 So. 2d 673, 678 (Fla. App. 2004) (confining convenience store clerk in back freezer room after tak- ing money from cash register ‘‘facilitated the robbers’ flight from the crime scene . . . and substantially les- sened the risk of quick detection’’); State v. Buggs, supra, 219 Kan. 215–16 (restraint or asportation that substantially lessens risk of detection is sufficient to constitute kidnapping). We conclude, then, that the fourth and fifth Salamon factors also tip in the respon- dent’s favor. 2 Turning to the sixth Salamon factor, we also agree with the respondent that shepherding a victim at gun- point into a back room of a retail establishment after having robbed her invariably ‘‘create[s] a significant danger or increase[s] the victim’s risk of harm indepen- dent of that posed by the separate offense.’’ State v. Salamon, supra, 287 Conn. 548. In Salamon, we sug- gested that the distinct danger that is relevant to the question of whether criminal conduct bears indepen- dent significance as kidnapping need not be physical danger. See id., 536. Criminal conduct that inspires dis- tinct fears or has a uniquely harmful psychological impact on the victim also qualifies. See id. (‘‘[a]mong the evils that both the common law and later statutory prohibitions against kidnapping sought to address were the isolation of a victim from the protections of society and the law and the special fear . . . inherent in such isolation’’). Other courts and commentators have reached the same conclusion. See, e.g., People v. Ngu- yen, 22 Cal. 4th 872, 886, 997 P.2d 493, 95 Cal. Rptr. 2d 178 (2000) (holding that conduct that substantially increases risk of psychological trauma to victim is legiti- mate basis for finding separate offense); 2 A.L.I., Model Penal Code and Commentaries (1980) § 212.1, p. 222 (discussing unique evil of kidnapping as means of ter- rorizing victim). Isolating and restraining victims at gunpoint after having robbed them causes them to experience fears that are different both in degree and in kind from the fears that naturally accompany being robbed. This is especially true in a highly visible commercial setting. When a retail store or restaurant is robbed, the victim reasonably may expect that the perpetrator will release her and flee the premises as soon as he has taken the property, bringing the danger to an end. When a perpe- trator opts to restrain a victim after a commercial rob- bery rather than leaving the premises, however, the victim justifiably fears that her ordeal may be just begin- ning. See, e.g., Latimore v. Barnes, Docket No. C11-5527 (SBA), 2015 WL 1406904, *2 (N.D. Cal. March 27, 2015). The case books are filled with instances in which a robber restrains, isolates, and/or moves his victims after taking their money as a prelude to committing addi- tional, more dangerous crimes. The robbery victim who is led at gunpoint away from the visibility of a commer- cial storefront understands that the offender may be isolating and restraining her not merely to facilitate his escape but as a prelude to a physical assault,10 sexual assault,11 use of the victim as a hostage or human shield,12 or even murder.13 The prospect is undeniably terrifying. See, e.g., Commonwealth v. Hughes, 264 Pa. Super. 118, 126, 399 A.2d 694 (1979); N. Kanellis, Note, ‘‘Kidnapping in Iowa: Movements Incidental to Sexual Abuse,’’ 67 Iowa L. Rev. 773, 782 (1982). It is undisputed that the victims in the present case did in fact experience such heightened and distinct psychological harm as a result of their postrobbery asportation and restraint. One of the victims, Feltman, testified that she feared for her life during the kidnap- ping. Another, Kozlowski, testified that he ducked down while imprisoned in the bathroom for fear that the peti- tioner would shoot him through the door. Defense coun- sel conceded as much in his closing argument, acknowledging that ‘‘all four victims had a very hard experience. . . . I will concede for you that . . . Wright and . . . Feltman had probably the most diffi- cult . . . harshest, the most traumatic experiences of their [lives] . . . .’’ Moreover, the harms and dangers involved in a post- robbery kidnapping are not solely psychological. Even if the perpetrator does not plan to assault, imperil, or kill his victims following a robbery, spiriting them at gunpoint to a more isolated location necessarily increases the risk that they will suffer serious physical injury or death. See, e.g., Eaglehorse v. State, 286 N.W.2d 329, 331 (S.D. 1979); see also Note, ‘‘A Rationale of the Law of Kidnapping,’’ 53 Colum. L. Rev. 540, 547–48 (1953). As the Supreme Court of California has explained, ‘‘[i]t takes but little imagination to envision the kind of violent events whose likelihood of occur- rence is great [when a kidnapping victim is forced to travel a great distance under the threat of injury by a deadly weapon]. Ready examples include not only desperate attempts by the victim to extricate himself but also unforeseen intervention by third parties.’’ Peo- ple v. Lara, 12 Cal. 3d 903, 908 n.4, 528 P.2d 365, 117 Cal. Rptr. 549 (1974); see, e.g., Latimore v. Barnes, supra, 2015 WL 1406904, *4 (in assessing whether restraint constitutes independent crime of ‘‘kidnapping to commit robbery,’’ jury considers ‘‘whether the move- ment increased a victim’s risk of harm . . . [including] the danger inherent in a victim’s foreseeable attempts to escape’’ (internal quotation marks omitted)); N. Kanellis, supra, 67 Iowa L. Rev. 782 (‘‘[t]aking a victim from familiar surroundings to an unknown location . . . may aggravate the victim’s [freedom seeking] impulses, causing the victim to attempt an escape and thus possibly incur more serious bodily harm’’ (footnote omitted)). Once again, one need not look far to find cases in which a victim, fearing that kidnapping would be a precursor to rape, assault, or murder, panicked or tried to resist, bringing about a tragic, self-fulfilling prophesy. See, e.g., People v. Laursen 8 Cal. 3d 192, 196, 501 P.2d 1145, 104 Cal. Rptr. 425 (1972) (motorist was shot when resisting kidnapping during escape from robbery), appeal dismissed and cert. denied, 412 U.S. 915, 93 S. Ct. 2738, 37 L. Ed. 2d 142 (1973); Johnson v. State, 281 Ga. App. 7, 8, 635 S.E.2d 278 (2006) (when robbery victim resisted being locked in camper, defen- dant struck him in head with revolver, causing him to fade in and out of consciousness). 3 When we examine the six Salamon factors, then, five of the factors most often will resolve in favor of the respondent when the perpetrator of a robbery forces his victims to leave the relative safety of a highly visible commercial store front and sequesters them in a more isolated area after having robbed them. The asportation and confinement take place after the completion of the primary objective of the robbery. The restraint is not inherent in the nature of the robbery, insofar as many, if not most, robberies culminate with the offender simply fleeing with the fruits of the robbery; leading a victim to a back room at gunpoint is no more linked to the crime of robbery than to rape, assault, or any other crime. Such removal and restraint typically are for the purpose of, and have the effect of, making it more difficult for the victim to summon assistance and reduc- ing the offender’s risk of detection, if not a prelude to the commission of a distinct crime, such as a sexual assault. Finally, the conduct necessarily subjects the victim to unique risks and harms, both physical and psychological, beyond those inherent in the robbery itself. Under such circumstances, these five factors almost invariably will outweigh the first factor—the nature and duration of the movement and confine- ment—which is more subjective and fact based, and takes center stage in close cases such as Salamon.14 D Finally, we take this opportunity to clarify some of the language in Salamon and Hinds that has been a source of confusion among litigants and the lower courts, the present case included. Specifically, in Sala- mon we stated that ‘‘[o]ur legislature, in replacing a single, broadly worded kidnapping provision with a gra- dated scheme that distinguishes kidnappings from unlawful restraints by the presence of an intent to pre- vent a victim’s liberation, intended to exclude from the scope of the more serious crime of kidnapping and its accompanying severe penalties those confinements or movements of a victim that are merely incidental to and necessary for the commission of another crime against that victim. Stated otherwise, to commit a kid- napping in conjunction with another crime, a defendant must intend to prevent the victim’s liberation for a longer period of time or to a greater degree than that which is necessary to commit the other crime.’’ (Emphasis added.) State v. Salamon, supra, 287 Conn. 542. Subsequently, in Hinds, in response to the dis- senting justices, the majority explained that, ‘‘by focus- ing solely on whether there was any restraint or asportation beyond that necessary for the commission of the sexual assault, the dissenting justices ignore[d] the ‘incidental to’ language in Salamon. . . . Restraint may be incidental to a sexual assault that is not neces- sary for its commission.’’ (Citations omitted; emphasis omitted.) Hinds v. Commissioner of Correction, supra, 321 Conn. 89–90. We did not invent the highlighted language in Sala- mon. Substantially similar articulations of the ‘‘inciden- tal and necessary’’ test appeared in the decisions of many of our sister states prior to Salamon. See, e.g., People v. Daniels, 71 Cal. 2d 1119, 1139, 459 P.2d 225, 80 Cal. Rptr. 897 (1969); Cejvanovic v. State, Docket No. 05-1226, 2006 WL 3614067, *2 (Iowa App. December 13, 2006) (decision without published opinion, 728 N.W.2d 223); State v. Robbins, 272 Kan. 158, 175, 32 P.3d 171 (2001); State v. Rogers, 17 Ohio St. 3d 174, 181, 478 N.E.2d 984, vacated on other grounds, 474 U.S. 1002, 106 S. Ct. 518, 88 L. Ed. 2d 452 (1985); State v. Atkin, 135 P.3d 894, 898–99 (Utah App.), cert. denied, 150 P.3d 58 (Utah 2006); State v. Harris, Docket No. 55561-8, 2006 WL 2246194, *2 (Wn. App. August 7, 2006) (decision without published opinion, 134 Wn. App. 1029), review denied, 160 Wn. 2d 1015, 161 P.3d 1027 (2007). Nevertheless, that language, both on its own and in conjunction with the cited language in Hinds, has led to confusion about, first, what it means for force or restraint to be necessary to the commission of a rape, robbery, or assault, and, second, whether the incidental and necessary test is to be understood as conjunctive or disjunctive. That is, does Salamon apply only when an offender’s conduct is not only incidental to but also necessary to commit the underlying crime, or is a defen- dant entitled to Salamon’s protections if either prong of the test applies (if, for example, restraint of the victim was incidental to a sexual assault but was not necessary to accomplish the assault). Both questions are front and center in the present case, in which the parties disagree over the proper application of the incidental and necessary test. With respect to the meaning of the word ‘‘necessary,’’ greater clarity may be achieved and ambiguities resolved by emphasizing three points often made by sister state courts. First, although restraint is not strictly necessary to accomplish a rape, robbery, or assault— restraint is not an essential element of those crimes— some degree of restraint, whether by physical force or threat and fear, almost always accompanies their commission. See Frederick v. State, 931 So. 2d 967, 970 (Fla. App. 2006); State v. White, 362 S.W.3d 559, 568 (Tenn. 2012). We have used the word ‘‘necessary’’ in that spirit. Second, our statement that kidnapping requires pre- vention of the victim’s liberation for a longer period of time or to a greater degree than that which is necessary to commit the underlying crime does not mean that an offender must commit the underlying crime in the least intrusive manner lest he be subjected to criminal liabil- ity for kidnapping. Hinds itself is an excellent illustra- tion of this point. We suggested in that case that if, for example, a jury concluded that the petitioner decided to move his victim the short distance from the parking lot where he abducted her to a nearby grassy area not to avoid detection or identification but, rather, because ‘‘he could not perform in the lit space [of the parking lot], or simply to avoid the hard paved surface while kneeling on the ground [as he assaulted her]’’; Hinds v. Commissioner of Correction, supra, 321 Conn. 80; then there was no indication that our legislature intended to criminalize his conduct as kidnapping merely because the act might have been completed less intrusively. See id., 79–80. Third, one complication of thinking about necessity in this manner is that doing so forces a reviewing court to confront thorny, angels on the head of a pin questions about the degree of restraint employed in any particular crime. Could an offender have accomplished a rape, robbery, or assault using less restraint? Would an under- lying crime committed less intrusively have been the same crime? To avoid having to confront these sorts of prickly metaphysical and counterfactual questions, sister state courts have framed the issue in terms of whether the restraint involved in a crime reflects a different criminal intention or creates a different risk of harm than that necessarily present in the underlying crime.15 In other words, the jury looks not to whether each of the offend- er’s specific physical actions was strictly necessary to commit the underlying crime but, instead, to whether his actions demonstrated an animus or purpose beyond that necessarily involved in the underlying crime (e.g., to wrongfully obtain property from, sexually violate, or physically injure the victim) or whether they imposed harms or risks on the victim beyond those that necessar- ily accompany any rape, robbery, or assault. Understanding Salamon in this way also resolves the second question that divided the parties and the members of the Appellate Court in this case and the companion case, namely, whether conduct that is merely incidental to but goes beyond that necessary to commit the underlying crime satisfies the legislative definition of kidnapping. The cited language from Sala- mon is ambiguous and, arguably, consistent with either party’s interpretation. Certainly, in Hinds, we suggested that the reading favored by the petitioner is the correct one; conduct that is wholly incidental to the commis- sion of an underlying crime cannot qualify as kidnap- ping, regardless of whether it is strictly necessary to commit that crime. See id., 89–90. Understanding neces- sity in the manner that we have suggested is consistent with that approach. It also is consistent with the approach followed by many of our sister state courts, on whose decisions we relied in Salamon. See State v. Salamon, supra, 287 Conn. 518, 527 and n.16. Those courts speak of restraints or restrictions on a victim’s liberty as being merely incidental to the underlying crime, necessary to commit the underlying crime, inherent in the nature of the underlying crime, and having no independent criminal significance, often using those and related expressions more or less interchangeably. See, e.g., United States v. Santistevan, 25 M.J. 123, 126 (C.M.A. 1987); Mackerley v. State, 754 So. 2d 132, 137 (Fla. App. 2000), quashed on other grounds, 777 So. 2d 969 (Fla. 2001); State v. Martin, 222 N.C. App. 213, 221, 729 S.E.2d 717, review denied, 366 N.C. 413, 735 S.E.2d 187 (2012), and review dismissed, 372 N.C. 300, 826 S.E.2d 710 (2019); see also F. Wozniak, Annot., ‘‘Seizure or Deten- tion for Purpose of Committing Rape, Robbery, or Other Offense as Constituting Separate Crime of Kidnapping,’’ 39 A.L.R.5th 283, 357, § 2[a] (1996) (describing tests used by different jurisdictions as being more or less formulaic ‘‘but not substantially different’’). Our own cases have, at times, followed the same approach. See, e.g., State v. Fields, supra, 302 Conn. 247, 252 (citing Salamon and conflating independent criminal signifi- cance, conduct that is not merely incidental to underly- ing offense, and restraint beyond that necessary to commit underlying offense). These various terms, then, are merely different ways of expressing the same concept, namely, whether the restraint imposed evidenced an independent criminal intent or subjected the victims to risks distinct from those necessarily entailed by or inherent in the underly- ing offenses. The six Salamon factors offer a useful framework for answering those questions. IV We therefore conclude that the petitioner cannot prevail on his claim under Salamon because the respon- dent has demonstrated, in light of the undisputed facts presented at trial, that the absence of the instruction mandated by Salamon gave rise to no discernible risk of prejudice, let alone a risk sufficient to undermine confidence in the verdict, such that a properly instructed jury would have found the petitioner guilty beyond a reasonable doubt. Indeed, as we explained, we agree with our sister state courts, which have con- cluded, as a matter of law, that, when a perpetrator, having taken his victims’ valuables, then leads them at gunpoint away from a highly visible commercial store- front and confines them in an isolated area of the store while he makes his escape, thereby exposing them to new and different risks, such conduct is not inherent in the nature of the robbery but, rather, indisputably has independent criminal significance.16 The judgment of the Appellate Court is reversed and the case is remanded to that court with direction to render judgment affirming the judgment of the habeas court. In this opinion ROBINSON, C. J., and MULLINS and KAHN, Js., concurred. * The listing of justices reflects their seniority status on this court as of the date of oral argument. ** May 12, 2021, the date that this decision was released as a slip opinion, is the operative date for all substantive and procedural purposes. 1 As we explain more fully hereinafter, the Brecht harmless error standard, as we apply it in the context of Salamon errors, requires essentially the same showing as that required for constitutional claims alleging ineffective assistance of counsel under Strickland v. Washington, 466 U.S. 668, 687, 104 S. Ct. 2052, 80 L. Ed. 2d 674 (1984), and suppression of material, exculpatory evidence under Brady v. Maryland, 373 U.S. 83, 87, 83 S. Ct. 1194, 10 L. Ed. 2d 215 (1963). 2 The relevant statutory text is discussed in part III B of this opinion. 3 After Luurtsema, we held, in Hinds v. Commissioner of Correction, 321 Conn. 56, 136 A.3d 596 (2016), that the procedural default rule does not bar postconviction claims that the trial court failed to instruct the jury as required under Salamon in cases rendered final before our decision in Salamon. Id., 61. We discuss our decision in Hinds in greater detail in parts II B and III D of this opinion. 4 After granting certification to appeal, this court ultimately determined in Epps that certification had been improvidently granted and dismissed the respondent’s appeal. See Epps v. Commissioner of Correction, 327 Conn. 482, 485, 175 A.3d 558 (2018). 5 As Justice Scalia noted in his concurring opinion in Dominguez Benitez, we also would observe that the very same critique can be leveled with respect to the other standards of prejudice/harmless error that we regularly apply. See United States v. Dominguez Benitez, supra, 542 U.S. 86–87 (Scalia, J., concurring in the judgment) (‘‘Such ineffable gradations of probability seem to me quite beyond the ability of the judicial mind (or any mind) to grasp, and thus harmful rather than helpful to the consistency and rationality of judicial [decision making]. That is especially so when they are applied to the hypothesizing of events that never in fact occurred. Such an enterprise is not [fact-finding], but closer to divination.’’). 6 The first concurrence also queries, first, why it is necessary to decide by which standard to assess the harmfulness of Salamon errors on collateral review and, second, whether it is fair to apply Brecht in the petitioner’s case when our trial courts and the Appellate Court, acting without the benefit of this opinion, have in the past applied Neder to other petitioners’ Salamon claims. The short answer to the first question is that it ordinarily is the duty of this court to clarify the law when called on to do so in the context of a justiciable case. In the present case, the respondent contends that the Appellate Court has applied the incorrect harmless error standard, and this court granted certification to address that question. Banks v. Com- missioner of Correction, 330 Conn. 950, 197 A.3d 391 (2018). Although it is true that, on rare occasion, we refrain, for prudential reasons, from resolving a legal question that is squarely and properly before us, that is the exception rather than the rule, and we perceive no compelling reason why we should shrink from our duty in this instance. The fact that today’s ruling potentially may impact a relatively small universe of future cases surely does not justify a failure to resolve the certified question, especially as the companion case itself demonstrates the broad range of configurations in which Salamon claims may present themselves. We are no more troubled by the first concurrence’s second charge. It is not at all uncommon for courts of last resort—the United States Supreme Court not least among them—to allow difficult legal questions to percolate in the lower courts for some time before ultimately resolving them. This, and the very nature of our judicial system, means that appellate tribunals frequently will resolve legal controversies in novel ways, such that future litigants are subject to rules different from those that bound past litigants. Far from unfair, this is the very essence of the common law. To hold ourselves yoked to a legal rule simply because the lower courts previously have applied it would be to turn the concept of controlling legal authority on its head. This we decline to do. 7 We note that one of our Salamon cases, namely, State v. Flores, 301 Conn. 77, 79, 17 A.3d 1025 (2011), did involve an underlying robbery and a conviction under § 53a-92 (a) (2) (B). In that case, we concluded that the lack of a Salamon instruction was not harmless error because, among other things, the victim was released immediately after the defendant forcibly took her property and the state did not argue that the restraint occurred for any longer than was necessary to commit the robbery. Id., 85, 87. For that reason, Flores is readily distinguishable from the present case. 8 There also was testimony that the petitioner originally sought to force his victims into the basement, which would have further isolated them, until he was informed that the stores had no basement. 9 Indeed, in his brief to this court, the petitioner essentially acknowledges that the victims were forced into the bathroom to facilitate his escape, stating that ‘‘it is conceivable that jurors would view the fact that [the] petitioner moved the employees into the bathrooms so that he could escape as being part and parcel of the robberies.’’ (Emphasis added.) 10 See, e.g., People v. Shay, 60 App. Div. 2d 698, 698, 400 N.Y.S.2d 383 (1977). 11 See, e.g., Lovette v. State, 636 So. 2d 1304, 1305–1306 (Fla. 1994); Mills v. State, 236 Ga. 365, 365, 223 S.E.2d 725 (1976); State v. Coleman, 865 S.W.2d 455, 456 (Tenn. 1993). 12 See, e.g., State v. Vue, Docket No. C4-92-86, 1992 WL 153093, *2 (Minn. App. July 7, 1992); People v. Addison, 151 App. Div. 2d 372, 372, 543 N.Y.S.2d 74, appeal denied, 74 N.Y.2d 946, 549 N.E.2d 483, 550 N.Y.S.2d 281 (1989), and appeal denied, 74 N.Y.2d 946, 549 N.E.2d 483, 550 N.Y.S.2d 281 (1989). 13 See, e.g., Lovette v. State, 636 So. 2d 1304, 1305–1306 (Fla. 1994); State v. Robinson, Docket No. 01C01-9207-CR-00234, 1993 WL 273953, *3 (Tenn. Crim. App. July 22, 1993). 14 We note that our conclusion that removing and restraining a victim after a robbery to facilitate the perpetrator’s escape usually holds independent criminal significance does not mean that there could not be close cases in which the failure to submit the question to a jury would constitute prejudicial error. For example, we would hesitate to find harmless a trial court’s failure to give the jury a Salamon instruction in a case in which the alleged postrob- bery conduct involved no asportation and only minimal restraint, such as a parting order that the victim lie on the ground or ‘‘don’t be a hero.’’ See, e.g., Hill v. State, 642 So. 2d 796, 797–98 (Fla. App. 1994) (jury could find restraint was incidental to robbery when perpetrators merely forced victims to lie down on floor before escaping); State v. White, 362 S.W.3d 559, 562–63 (Tenn. 2012) (whether confinement was incident to robbery was question for jury when defendant, while leaving scene of robbery, removed telephones and directed victims to lie down on floor and wait eight or nine minutes). It is debatable, for example, whether the victims are placed at increased risk of harm under such circumstances. The present case, however, is funda- mentally different from those cases. The petitioner took each victim at gunpoint to a different, more isolated part of the store, where he ordered them to remain confined in an enclosed space and attempted to block their escape. 15 See, e.g., People v. Daniels, supra, 71 Cal. 2d 1139 (‘‘the intent of the [California] [l]egislature . . . was to exclude from [the] reach [of the felony kidnapping statute] not only standstill robberies . . . but also those in which the movements of the victim are merely incidental to the commission of the robbery and do not substantially increase the risk of harm over and above that necessarily present in the crime of robbery itself’’ (citation omitted; emphasis added; internal quotation marks omitted)); State v. Hart- ley, Docket No. 90AP-859, 1991 WL 132417, *6 (Ohio App. July 18, 1991) (because ‘‘the kidnapping by deception in order to lure [the victim] to a place where he could be raped involved a separate animus from the restraint necessary to effectuate the rape . . . the trial court properly sentenced the [defendant] to consecutive sentences for rape and kidnapping’’); State v. Rollins, 605 S.W.2d 828, 830 (Tenn. Crim. App. 1980) (‘‘a number of courts have held that the forced movement of a crime victim during the course of a crime [that] is merely incidental to the perpetration of the crime, as from one room of a house to another, is not kidnapping if there is no substantially increased risk of harm over and above that necessarily present in the crime of robbery itself’’ (emphasis added)); State v. Williams, Docket No. 36772- 2-I, 1997 WL 469623, *3 (Wn. App. August 18, 1997) (relevant issue to consider in determining if confinement, movement or detention is sufficient to warrant separate kidnapping conviction is ‘‘whether the defendant’s conduct substan- tially increased [the] risk of harm over and above that necessarily present in the [underlying] crime . . . itself’’ (internal quotation marks omitted)), review denied, 134 Wn. 2d 1026, 958 P.2d 315 (1998). 16 Consequently, it is apparent, as Judge Keller concluded; see Banks v. Commissioner of Correction, supra, 184 Conn. App. 133 (Keller, J., dis- senting); that the petitioner could not prevail on his claim, even if we agreed with him that the respondent was required to establish harmlessness beyond a reasonable doubt. The concurring justices do not disagree with this con- clusion.
