ECKER, J. The petitioner, James A. Mitchell, appealed from the trial court's denial of his request for leave to file a late petition for certification to appeal from the court's judgment denying his petition for a new criminal trial on the ground that the petitioner's claims were "meritless and too late." The Appellate Court rejected the petitioner's claim that the trial court improperly considered the merits of the petition, rather than the reasons for the delay or any other factors relevant to permitting a late filing, and dismissed the appeal. See Mitchell v. State , 188 Conn. App. 245, 247, 204 A.3d 807 (2019). We conclude that the trial court abused its discretion by failing to engage in the proper analysis to determine whether to excuse the late petition for certification. We further conclude, however, that the trial court acted within its discretion when it determined that the petition did not raise issues warranting certification and, therefore, affirm the Appellate Court's judgment dismissing the petitioner's appeal on this alternative basis.

I

The record reveals the following procedural history culminating in the present appeal. Following a jury trial, the petitioner was convicted of attempt to commit murder in violation of General Statutes §§ 53a-8, 53a-49 (a) and 53a-54a (a), conspiracy to commit murder in violation of General Statutes §§ 53a-48 (a) and 53a-54a (a), kidnapping in the first degree in violation of General Statutes §§ 53a-8 and 53a-92 (a) (2) (A), conspiracy to commit kidnapping in the first degree in violation of §§ 53a-48 and 53a-92 (a) (2) (A), sexual assault in the first degree in violation of General Statutes §§ 53a-8 and 53a-70 (a) (1), conspiracy to commit sexual assault in the first degree in violation of §§ 53a-48 and 53a-70 (a) (1), assault in the first degree in violation of General Statutes §§ 53a-8 and 53a-59 (a) (5), conspiracy to commit assault in the first degree in violation of §§ 53a-48 (a) and 53a-59 (a) (5), and criminal possession of a firearm in violation of General Statutes (Rev. to 2003) § 53a-217 (a) (1). See State v. Mitchell , 110 Conn. App. 305, 307–308, 955 A.2d 84, cert. denied, 289 Conn. 946, 959 A.2d 1012 (2008). The trial court, Mullarkey , J. , imposed a total effective sentence of fifty-seven years imprisonment. Id., at 310, 955 A.2d 84. The Appellate Court affirmed the petitioner's conviction on direct appeal. Id., at 308, 329, 955 A.2d 84.

The petitioner subsequently sought postconviction relief by way of a petition for a new trial and a petition for a writ of habeas corpus. The petitioner was represented by the same attorney in both proceedings. Trial proceeded first on the later filed habeas petition. The habeas court, Cobb , J., denied the petition and thereafter granted the petitioner's petition for certification to appeal pursuant to General Statutes § 52-470 (g). The Appellate Court affirmed the habeas court's judgment. Mitchell v. Commissioner of Correction , 156 Conn. App. 402, 404, 421, 114 A.3d 168, cert. denied, 317 Conn. 904, 114 A.3d 1220 (2015).

Trial then commenced on the petition for a new trial, before the same judge who had presided over the petitioner's criminal trial. On August 22, 2016, the trial court, Hon. Edward J. Mullarkey , judge trial referee, rendered judgment denying the petition. On September 12, 2016, the petitioner filed a request for an extension of time to file his appeal, which the trial court granted on September 13. The petitioner then filed his appeal within the extended deadline.

When the petitioner filed the appeal from the trial court's denial of his petition for a new trial, he did so without first obtaining certification to do so in accordance with General Statutes § 54-95 (a), which provides that certification to appeal shall be obtained "within ten days after the judgment is rendered ...." See Santiago v. State , 261 Conn. 533, 543–44, 804 A.2d 801 (2002). That appeal had been pending for almost one year when, on September 5, 2017, the Appellate Court notified the petitioner that the requisite certification to appeal was lacking. On September 8, 2017, prior to the hearing in the Appellate Court to show cause why his appeal should not be dismissed, the petitioner filed in the trial court a request for leave to file a petition for certification to appeal, to which the petition for certification was appended. To explain his failure to seek certification within the statutory time limitation, the petitioner alleged in that request that, "[a]lthough analogous to a petition for certification to appeal in a habeas corpus case, the petitioner was not provided with a written notice of appeal procedures via [Judicial Branch] form JD-CR-84, as is the custom in habeas corpus cases ...." The respondent, the state of Connecticut, filed an opposition to the request. Its opposition cited the one year delay in seeking certification and the frivolousness of the grounds raised in the petition for a new trial. Before argument was heard on the request, the Appellate Court dismissed the petitioner's appeal for failure to obtain certification in compliance with § 54-95 (a).

Argument proceeded in the trial court on the petitioner's request for leave to file the petition for certification to appeal. The court orally denied the request at the conclusion of the hearing and subsequently issued a written decision. The decision noted the ten day statutory time limit prescribed for seeking certification to appeal but did not address any particular facts regarding the petitioner's excuse for failing to meet that requirement or the significance of the procedural nonconformity. Instead, it summarized reasons why the court previously had determined that the principal evidence on which the new trial petition relied would not have changed the outcome had such evidence been available at the criminal trial. It then concluded that the petitioner's claims were "meritless and too late."

The petitioner appealed to the Appellate Court, claiming "that the [trial] court abused its discretion in denying his request because the court, in considering the length of the delay in filing the request, did not consider the reasons for the delay or any other factors relevant to permitting a late filing but, rather, addressed the merits of the petitioner's appeal." Mitchell v. State , supra, 188 Conn. App. at 247, 204 A.3d 807. The Appellate Court dismissed the appeal. Id. It reasoned that, "although the petitioner is correct that [the trial court] referenced the merits of the petitioner's claims on appeal, it also made clear that its decision was based in large part on the petitioner's delay ...." Id., at 250, 204 A.3d 807. The Appellate Court acknowledged that the petitioner's request for leave had attributed the delay to not having been provided with a written notice of appeal procedures but concluded that this fact could not excuse the delay because no such notice was required and, even if it were, the failure to afford that notice would not operate as a waiver of the certification requirement. Id. The Appellate Court also acknowledged that the trial court never expressly addressed the notice issue but opined that, "by considering the length of the petitioner's delay, the court afforded due regard to the reasons for the delay, and, thus, the court's denial of the petitioner's request for leave to file a late petition for certification to appeal was not an abuse of discretion." Id.

We granted the petitioner's petition for certification to appeal to this court to decide whether the Appellate Court correctly concluded that the trial court did not abuse its discretion in denying the petitioner's late petition for certification to appeal. See Mitchell v. State , 331 Conn. 920, 205 A.3d 567 (2019). The threshold question raised by the certified issue is whether the trial court improperly ignored considerations relevant to assessing whether to excuse a late request for certification to appeal. Because we answer that question in the affirmative, we also consider whether the trial court's decision could be sustained on the basis of its determination that the petition for a new trial raised no claims warranting appellate review. We conclude that this latter determination was not an abuse of discretion.

II

The petitioner contends that the trial court abused its discretion when it denied his request for leave to file the petition for certification because that decision was not made in accordance with this court's direction in Santiago v. State , supra, 261 Conn. at 543, 804 A.2d 801. He argues that, in assessing the length of the delay, the trial court improperly failed to discount the period during which he was pursuing the appeal from the denial of his petition. This argument was raised at the hearing before the trial court and in the petitioner's Appellate Court brief, but it was not addressed by the Appellate Court. The petitioner also renews the argument that was rejected by the Appellate Court, namely, that the trial court improperly considered the merits of the petition for certification rather than the reasons for delay and other factors relevant to the timeliness of his request for certification. We agree, in part, with the petitioner's second argument.

A petition for a new trial, like a petition for a writ of habeas corpus, provides a "critical procedural mechanism for remedying an injustice." Seebeck v. State , 246 Conn. 514, 531, 717 A.2d 1161 (1998). If a new trial petition is denied, there is a statutory right to appeal, subject to this condition: "No appeal may be taken from a judgment denying a petition for a new trial unless, within ten days after the judgment is rendered, the judge who heard the case or a judge of the Supreme Court or the Appellate Court, as the case may be, certifies that a question is involved in the decision which ought to be reviewed by the Supreme Court or by the Appellate Court." General Statutes § 54-95 (a).

The legislature adopted certification requirements to eliminate frivolous postconviction appeals. Seebeck v. State , supra, 246 Conn. at 531, 717 A.2d 1161. Certification requirements were concurrently adopted for appeals from the denial of a habeas petition and appeals from the denial of a new trial petition. Id., at 530, 717 A.2d 1161 ; see also 7 S. Proc., Pt. 5, 1957 Sess., pp. 2936–40, remarks of Senator Elmer S. Watson. Both schemes prescribe a ten day period after judgment is rendered for filing the petition for certification. See General Statutes §§ 52-470 (g) and 54-95 (a).

To determine the contours of the requirements set forth in § 54-95, this court has looked to the more developed body of habeas case law considering the certification requirement in § 52-470. See, e.g., Santiago v. State , supra, 261 Conn. at 537–40, 804 A.2d 801 ; Seebeck v. State , supra, 246 Conn. at 529–33, 717 A.2d 1161. We held in Seebeck that the legislature did not intend for the certification requirement to limit the jurisdiction of the appellate tribunal but only to define the scope of appellate review. See Seebeck v. State , supra, at 533, 717 A.2d 1161. We also concluded that the same standard of review applied under both statutes, namely, whether the trial court clearly abused its discretion in denying the request for certification to appeal. Id., at 533–34, 717 A.2d 1161. In Santiago , we concluded that, although the certification requirement is not jurisdictional in nature, it is nonetheless a mandatory prerequisite to appeal from the denial of a new trial petition because of the essential purpose that certification serves. See Santiago v. State , supra, at 539–40, 804 A.2d 801. We further held that, because this requirement serves important public and institutional policy objectives independent of, and paramount to, the state's particularized interest in any specific case—namely, the conservation of judicial resources—it is not subject to waiver due to the state's failure to move to dismiss the appeal within the time limit prescribed for the dismissal of nonjurisdictional defects under our rules of practice. See id., at 543–44, 804 A.2d 801, citing Practice Book § 66-8.

Although Santiago refused to countenance abject noncompliance with the certification requirement, this court recognized in that case that noncompliance was a defect that could be cured even after the statutorily prescribed time limit. We observed: "In the event that the petitioner does seek certification to appeal from the judgment of the trial court denying his petition for a new trial, that court will be required to decide whether to excuse the petitioner's delay in filing his petition for certification to appeal ... with due regard to the length of the delay, the reasons for the delay, and any other relevant factors . In considering the length of the delay, the trial court should be mindful of the fact that most of that delay is attributable to the petitioner's efforts to seek direct appellate review from the judgment denying his petition for a new trial. Because the procedural avenue followed by the petitioner in [ Santiago ] appears to have raised an issue of first impression in this state, we do not believe that the delay resulting from the appellate litigation of that issue should be weighed heavily, if at all, against the petitioner." (Citation omitted; emphasis added.) Id., at 545 n.18, 804 A.2d 801. We noted that the decision whether to entertain an untimely request for certification to appeal would be a matter left to the trial court's discretion but again underscored that, "[i]n exercising that discretion, the court should consider the reasons for the delay." Id., at 544–45 n.17, 804 A.2d 801.

The present case provides our first opportunity since Santiago to consider a trial court's exercise of discretion to deny leave to file a late petition for certification under § 54-95. Our consideration of this issue is subject to the general principle that "every reasonable presumption should be given in favor of the correctness of the court's ruling." (Emphasis added; internal quotation marks omitted.) Alliance Partners, Inc. v. Voltarc Technologies, Inc. , 263 Conn. 204, 210, 820 A.2d 224 (2003). A presumption of correctness will not carry the day when there is evidence that the trial court failed to follow the applicable law. See, e.g., Rosenblit v. Danaher , 206 Conn. 125, 134, 537 A.2d 145 (1988) ; Disciplinary Counsel v. Parnoff , 158 Conn. App. 454, 470, 119 A.3d 621 (2015), aff'd, 324 Conn. 505, 152 A.3d 1222 (2016). In particular, it is an abuse of discretion to rely on "improper or irrelevant factors"; (internal quotation marks omitted) Georges v. OB-GYN Services, P.C. , 335 Conn. 669, 687, 240 A.3d 249 (2020) ; accord State v. Holley , 327 Conn. 576, 628, 175 A.3d 514 (2018) ; or to fail to consider the reason for an untimely filing, if one is advanced by the petitioner. See Roberto v. Honeywell, Inc. , 33 Conn. App. 619, 625–26, 637 A.2d 405, cert. denied, 229 Conn. 909, 642 A.2d 1205 (1994) ; Segretario v. Stewart-Warner Corp. , 9 Conn. App. 355, 362, 519 A.2d 76 (1986) ; see also Alvarado v. Commissioner of Correction , 75 Conn. App. 894, 895–96, 818 A.2d 797 (rejecting argument that trial court had affirmative duty, sua sponte, to inquire into reasons for untimely petition for certification to appeal), cert. denied, 264 Conn. 903, 823 A.2d 1220 (2003).

In addition to these general principles, one further consideration specific to petitions for a new trial bears on the trial court's treatment of an untimely request for certification under § 54-95. In the intervening period since Santiago , this court has made clear that, because there is no constitutional or statutory right to counsel in connection with a petition for a new trial, there is no right to effective assistance of counsel in such a proceeding. See Breton v. Commissioner of Correction , 325 Conn. 640, 701–702, 159 A.3d 1112 (2017). What this means for present purposes is that, if a request for certification to appeal is untimely filed due to counsel's negligence, and the delay is not excused, the petitioner has no recourse in any forum. His appellate rights are forfeited, and we are unaware of any means under current law by which he can seek relief for counsel's ineffective assistance in the loss of a potentially meritorious appeal. The irremediable and absolute character of the forfeiture in new trial proceedings resulting from a lawyer's failure to comply with a nonjurisdictional time limitation does not compel excusal of every untimely request for certification to appeal. But it does elevate the importance of the trial court's obligation to give "due regard to the length of the delay, the reasons for the delay, and any other relevant factors"; (emphasis added) Santiago v. State , supra, 261 Conn. at 545 n.18, 804 A.2d 801 ; and call for a reviewing court to ensure that the record fairly reflects that this obligation has been met. Cf. Alliance Partners, Inc. v. Voltarc Technologies, Inc. , supra, 263 Conn. at 211, 820 A.2d 224 (discretion vested in trial court "imports something more than leeway in decision making and ... should not impede or defeat the ends of substantial justice" (internal quotation marks omitted)).

With this observation and Santiago ’s directive in mind, we review the trial court's memorandum of decision in the present case denying the petitioner's request for leave to file the late petition for certification. The trial court's decision began by reciting the mechanisms through which the petitioner unsuccessfully had sought a new trial: a direct appeal, a habeas petition, and a petition for a new trial. The trial court noted the substantial overlap in the issues raised in the habeas and new trial petitions, "with the addition of an unsubstantiated claim of newly discovered evidence." It then briefly summarized the reasons why it had rejected the principal claim in the petition for a new trial regarding security camera still frames and videotape capturing certain parts of the incident giving rise to the criminal charges.

The trial court then turned to the requirement to obtain certification to appeal, stating: "[ Section] 54-95 (a) required the petitioner to file within ten days after the judgment is rendered. [The] court, in good conscience, cannot find that the issue(s) raised ought to be reviewed by a higher court. Santiago v. State , [supra, 261 Conn. at 533, 804 A.2d 801 ]." This conclusion was followed by an explanation that apparently referred back to the court's earlier discussion regarding the lack of merit to the security camera issue: "Similarly , claims concerning former [Hartford Police Detective] Alfred Henderson's posttrial arrest would not have had any effect on the petitioner's jury trial. The petitioner's coconspirator [Travis Hampton] was tried by the same court four months after the petitioner. Unlike the petitioner, Hampton did not testify and admit [to] being at the scenes of the crimes. He was convicted of nine felonies in a case in which a different detective testified. State v. Hampton , 293 Conn. 435 (2009). The petitioner's claims are meritless and too late. Iovieno v. Commissioner of Correction , 242 Conn. 689 (1997).

"Request denied." (Emphasis added.)

We conclude that the trial court's ruling, although adequate in certain respects, fails to fully comport with our direction in Santiago .

With respect to Santiago ’s first requirement, which instructs the trial court to give due consideration to the length of the delay, the only reference to this factor in the trial court's decision is its acknowledgement of the statutorily prescribed time limit and its conclusion that the petitioner's claims are "meritless and too late ." (Emphasis added.) Both parties agree that there is no indication that the trial court gave any consideration to the existence or circumstances of the appellate litigation when assessing the length of the delay, an issue raised by the petitioner at the hearing before the trial court. The petitioner argues that Santiago directed the trial court to take the appellate litigation into account, whereas the state argues that, under the present circumstances, the appellate litigation was not relevant to the delay in seeking certification.

We do not entirely agree with either party's position. The state is correct that the appellate litigation in Santiago , unlike in the present case, was in pursuit of an issue of first impression that, if successful, could have excused the failure to seek certification. See footnote 5 of this opinion. But this reasoning does not make the course and duration of the appellate litigation per se irrelevant in cases arising after Santiago . Other facts relating to the appellate litigation were pertinent to assessing the length of the delay in the present case. Specifically, the petitioner's counsel, evidently unaware of the certification requirement in § 54-95 (a), filed what otherwise would have been a timely appeal from the denial of the new trial petition, having obtained an extension of time to file that appeal. The trial court granted that extension, notwithstanding the procedural irregularity that ultimately returned the petitioner to the trial court, and did so without alerting the petitioner to the fact that his appeal could not proceed without certification. The Appellate Court similarly granted the petitioner an extension of time to file his appellate brief, which he then filed in due course; the extension was granted without any notification to the petitioner that the appeal could not proceed without the missing certification. The Appellate Court thereafter granted the state two extensions of time to file its brief but, again, did not notify the petitioner until months later that his appeal could not proceed without certification. No doubt it was the petitioner's responsibility to ensure that he complied with the statutory requirements. Nonetheless, the repeated failure of two different courts to bring this defect to the petitioner's attention, while at the same time approving extension requests, as well as the state's decision to seek extensions of time for filing its appellate brief rather than moving to dismiss the appeal, could well have affected a trial court's assessment of the fairness of holding the petitioner strictly accountable for the entire year's delay in seeking certification.

Notwithstanding our concerns, we cannot say that the trial court failed to give due regard to the length of the delay under the circumstances presented. The petitioner did not draw this particular aspect of the appellate litigation to the trial court's attention; instead, he incorrectly assumed that Santiago suggested that the trial court always should discount the period of appellate litigation in assessing the length of the delay. In the absence of any focused argument by the petitioner, it was sufficient for the trial court to acknowledge the statutory time limit and to state a conclusion that the claims were "too late."

We reach a different conclusion with respect to the question whether the trial court gave due regard to the reason for the delay. As the Appellate Court recognized, the petitioner did clearly assert a reason for the delay in his request, namely, the lack of notice to the petitioner of appellate procedures like the notice provided in habeas appeals. The trial court is not entitled to a presumption that it gave due consideration to this claim under the circumstances presented. There is not a single phrase or statement in the record, either during the hearing on the petitioner's request or in the trial court's decision, from which we reasonably could infer that the trial court considered the proffered reason for the delay. The Appellate Court's conclusion to the contrary rested on an untenable assumption—that the trial court considered the reason for the delay when it considered the length of the delay. This conclusion ignores that the reason for the delay is a distinct, nontemporal factor that must be considered under Santiago . It may be that the longer the delay, the more compelling the reason must be to excuse that delay. But, even under such a rationale, consideration of the latter is not subsumed by an assessment of the former in the absence of an indication of any kind that the petitioner's proffered excuse was duly considered.

The record does not even reflect any indication that the trial court understood that it was obligated, as directed by Santiago , to give due regard to the reason for the delay. The factors identified in Santiago were never mentioned in the court's decision or in its comments at the hearing. Although the trial court was not required to credit the reason offered by the petitioner, it was required, at a minimum, to give some indication that it had at least considered whether the proffered reason excused the delay under the circumstances. See Carter v. State , 194 Conn. App. 208, 215, 220 A.3d 886 (2019) (trial court's order sufficiently demonstrated that it had considered petitioner's stated reason for delay in filing petition, as required by Santiago , by stating that "the petitioner has failed to establish good cause for a delay of over four months after the expiration of the appeal period" (internal quotation marks omitted)); cf. Worden v. Francis , 170 Conn. 186, 188, 365 A.2d 1205 (1976) ("[w]ithout repeating all the considerations mentioned by the trial court, it suffices to note that the court fully realized the discretionary power it was called upon to exercise and concluded that ‘[w]hile the court is empowered to grant the motion [for a late substitution] upon a finding of good cause, good cause has not been shown by the plaintiff’ "); Kendzierski v. Goodson , 21 Conn. App. 424, 427, 574 A.2d 249 (1990) (trial court did not ignore good cause requirement for termination because, "[a]lthough the court did not explicitly use the term ‘good cause,’ it is clear, from the context of the court's ruling and from its specific finding that the plaintiff proved a desire for a higher rent, that its decision was based on the good cause requirement"). It is especially important to do so when, as here, the consequences of an adverse determination involve the permanent and irrevocable loss of the petitioner's ability to seek relief.

It may well be appropriate for us to overlook the trial court's failure to consider the reason offered by the petitioner for the delay if that reason could not have provided a basis to excuse the untimely request for certification, had it been considered. However, we are not persuaded that the trial court, giving due consideration to the reason proffered by counsel, would have been compelled to deny the request under these circumstances.

The petitioner's request alleged that, "[a]lthough analogous to a petition for certification to appeal in a habeas corpus case, the petitioner was not provided with a written notice of appeal procedures via [Judicial Branch] form JD-CR-84, as is the custom in habeas corpus cases ...." The record indicates that, in his earlier habeas proceedings in which he presumably was afforded such notice, the petitioner filed a timely request for certification to appeal. The petitioner did not argue that there is legal authority requiring similar notice in new trial petition proceedings; nor did he argue that the statutory certification requirement was ambiguous. He thus was effectively making an equitable argument, i.e., that the custom of providing notice of the certification requirement in habeas proceedings demonstrates an awareness that it is an important procedural hurdle that could be overlooked in the absence of special mention and that he was lulled into error by his prior experience in his habeas case, in which he did comply with the certification requirement after having received notice.

We have not previously considered what constitutes an adequate reason to excuse delay in this context. The petitioner's attorney conceded at oral argument before this court that, regardless of his lack of actual knowledge of the statutory certification requirement, he had a duty to ascertain the pertinent appeal requirements. Attorney negligence generally has not been deemed to constitute good cause for an untimely action in other contexts. See, e.g., Georges v. OB-GYN Services, P.C. , supra, 335 Conn. at 691, 240 A.3d 249 (late appeal under Practice Book § 63-1 ); Alliance Partners, Inc. v. Voltarc Technologies, Inc. , supra, 263 Conn. at 207–209, 820 A.2d 224 (same); Jaquith v. Revson , 159 Conn. 427, 431–32, 270 A.2d 559 (1970) (motion to open judgment of nonsuit rendered for lack of timely compliance with court order); see also Percy v. Lamar Central Outdoor, LLC , 147 Conn. App. 815, 819–20, 83 A.3d 1212 (motion to set aside default on basis of attorney negligence), cert. denied, 311 Conn. 932, 87 A.3d 580 (2014). In the context of a late filed petition for certification to appeal under § 54-95 (a), however, we discern important distinguishing characteristics that could persuade a trial court, in its discretion, to consider an attorney's negligence as a valid excuse under the present circumstances. In particular, the litigant lacks any meaningful remedy for his attorney's negligence if the delay is not excused, the attorney otherwise diligently pursued the appellate litigation, the courts and the state also apparently overlooked the certification requirement when sanctioning extensions of time to pursue the appeal in the absence of a request for or grant of certification, neither the state nor the trial court suggested that the delay resulted in any prejudice to the state or the court system, and a lengthy term of imprisonment is at stake.

Other factors that have been considered in weighing whether to excuse untimely actions in other contexts have taken into account whether the delay was intentional or for strategic advantage; see, e.g., State v. L'Heureux , 166 Conn. 312, 319–20, 348 A.2d 578 (1974) ; Meribear Productions, Inc. v. Frank , 193 Conn. App. 598, 606, 219 A.3d 973 (2019) ; whether the delay could be personally attributed to the client; see, e.g., Janulawicz v. Commissioner of Correction , 310 Conn. 265, 274 n.11, 77 A.3d 113 (2013) ; Ramos v. Commissioner of Correction , 248 Conn. 52, 61–62, 727 A.2d 213 (1999) ; Langston v. Commissioner of Correction , 185 Conn. App. 528, 532–33, 197 A.3d 1034 (2018), appeal dismissed, 335 Conn. 1, 225 A.3d 282 (2020) ; and whether the delay caused prejudice to the opposing party. See, e.g., Janulawicz v. Commissioner of Correction , supra, at 274–75, 77 A.3d 113 ; Horton v. Meskill , 187 Conn. 187, 194, 445 A.2d 579 (1982) ; Meribear Products, Inc. v. Frank , supra, at 606, 219 A.3d 973 ; Warner v. Lancia , 46 Conn. App. 150, 157, 698 A.2d 938 (1997). None of those concerns is implicated in the present case.

We therefore conclude that the trial court abused its discretion when it failed to accord due and proper consideration to the reason for the delay in deciding whether to excuse the untimely request for certification.

III Our decision to venture beyond the trial court's procedural holding and to review the merits of the appeal is made easier because there is no dispute that the trial court itself reached a conclusion on the merits of the petition for certification. This fact is clear not merely from the court's final pronouncement that the petitioner's claims are "meritless and too late" but by its statement that, "in good conscience, [it] cannot find that the issue(s) raised ought to be reviewed by a higher court," which mirrors the statutory standard for certification. See General Statutes § 54-95 (a) ("the judge who heard the case ... certifies that a question is involved in the decision which ought to be reviewed by the Supreme Court or by the Appellate Court " (emphasis added)). The trial court's decision sets forth reasons to explain this conclusion as to the principal grounds raised in the petition. Although the petitioner contends that the trial court improperly considered the merits of his petition as a basis to deny leave to file the petition for certification, we ascribe a different intention to the court in making that determination. We construe the court's decision to conclude, in effect, that (1) the request for certification to appeal was untimely, and, therefore, it would not grant leave to seek certification, and (2) alternatively, even if it were to excuse the untimely request, it would not grant certification to appeal. In light of our conclusion in part II of this opinion, the first ground cannot sustain the court's decision. We therefore consider this alternative ground. We conclude that the trial court did not abuse its discretion in finding no merit to the claims and affirm the judgment of the Appellate Court on that basis.

The petitioner sought a new trial on the basis of newly discovered evidence, as well as "for other reasonable cause ...." General Statutes § 52-270 (a). To assess whether the trial court correctly concluded that the petitioner raised no claims in his petition for a new trial that warranted appellate review, we begin with the evidence presented at his criminal trial to provide the necessary context. See Shabazz v. State , 259 Conn. 811, 827, 792 A.2d 797 (2002) (when ruling on petition for new trial, "[t]he trial court must always consider the newly discovered evidence in the context of the evidence presented in the original trial").

A

In the petitioner's direct appeal from his conviction, the Appellate Court set forth the following facts that the jury reasonably could have found, which we have supplemented with additional facts relevant to the present appeal. "On August 23, 2003, following an evening at a nightclub, the victim was dropped off at a friend's house in East Hartford. Wanting to return home, and with her residence too distant to walk, the victim called the [petitioner] for a ride [after she was unsuccessful in getting a ride from several other friends]. The victim chose to call the [petitioner] because she knew that Denasha Sanders, the mother of one of the [petitioner's] children, had lived in the same building as the victim and that the [petitioner] was frequently in the vicinity. ...

"The [petitioner] arrived driving a gold Nissan Altima accompanied by another man, unknown to the victim at the time, but later identified as ... Hampton. The victim agreed to go with the [petitioner] and Hampton to downtown Hartford to get something to eat. [When they arrived at the restaurant, the petitioner remained in the car, speaking to Sanders on his cell phone, while the victim and Hampton went into the restaurant. After they returned to the car], the [petitioner] became violent with the victim, striking her with his cell phone and demanding to know the location of the victim's brother [who had been dating Sanders]. Out of fear that the [petitioner] would harm her [brother], the victim lied to the [petitioner] and told him that her brother was at her grandfather's house. The victim attempted to leave the car, but the [petitioner] pulled her by the hair and locked the doors. During this time, Hampton remained in the backseat of the vehicle.

"The [petitioner] subsequently determined that the victim's brother was not at her grandfather's house. He drove the victim and Hampton to his mother's house in Hartford and ordered the victim out of the car. The victim briefly complied and then returned to the vehicle while the [petitioner] and Hampton entered the house. When the [petitioner] and Hampton returned, the three proceeded to leave the area by car. The [petitioner] apologized to the victim for hitting her and offered her marijuana, which she accepted. Instead of driving the victim [south on Market Street toward her home, however, the petitioner turned north on Market Street and parked behind a building on Market and Pequot Streets, on the opposite corner from a Citgo gas station]. The [petitioner] told the victim he wanted to have sex with her and proposed that they go to a hotel ....

"The victim refused and got out of the car, intending to walk home. The [petitioner] produced a shotgun, which he gave to Hampton, who pointed the weapon at the victim's face. The [petitioner] and Hampton told the victim to remove her pants. The victim [complied, and] the [petitioner then] raped her vaginally from behind [while Hampton pointed the shotgun at her face]. When the [petitioner] was finished, he [regained possession of the shotgun and demanded that] the victim ... perform fellatio on Hampton. The victim complied briefly, [but when she refused to continue] Hampton [penetrated her vaginally for a moment], while the [petitioner] ... held the shotgun. [When Hampton stopped, the] victim grabbed her pants ... yelled at the [petitioner] to let her leave [and promised that she would not tell anyone what had happened]. The [petitioner] told the victim she could [either] get into a nearby dumpster or run. As the victim attempted to run, the [petitioner] shot her in the side of the stomach. The victim [ran across Pequot Street toward the Citgo station but was] followed by Hampton, who now had the shotgun. The [petitioner] pursued the victim in the car and blocked her path. [The victim ran from the Citgo station across Market Street and attempted to hide behind a tree on Market Street, but Hampton found her and shot her several times. At one point, she heard the petitioner say to Hampton ‘[m]ake sure that bitch is dead.’ The victim held her breath and attempted to play dead. The petitioner and Hampton] then left the scene [in the vehicle]. Shortly thereafter, [they] returned briefly [stopped the vehicle close to the victim's location to see if she was dead] and then left the area again. The victim [grabbed her left arm, which was almost severed by a gunshot blast to her elbow, and] dragged herself to the street, where she was found by a passing driver. The police and paramedics were summoned, and the victim was taken to Hartford Hospital for treatment." (Footnote in original.) State v. Mitchell , supra, 110 Conn. App. at 308–10, 955 A.2d 84.

The victim identified the petitioner as the perpetrator shortly after her breathing tube was removed following surgery. He was arrested and charged with attempt to commit murder, conspiracy to commit murder, kidnapping in the first degree, conspiracy to commit kidnapping in the first degree, sexual assault in the first degree, conspiracy to commit sexual assault in the first degree, assault in the first degree, conspiracy to commit assault in the first degree, and criminal possession of a firearm.

At the petitioner's criminal trial, the state offered corroborating forensic and testimonial evidence to establish the version of events described in the preceding paragraphs, although no forensic evidence directly implicated the petitioner. Among other things, the state offered the testimony of two eyewitnesses, who heard gunshots, saw a gold colored vehicle in pursuit of someone on foot, saw someone get out of the vehicle, and watched the vehicle circle back to the victim before leaving. The state also offered a videotape and still photographs from security cameras positioned around Travelers Tower near Market Street. These exhibits provided grainy images of a portion of the incident. The state used this photographic evidence to prove, among other things, that the petitioner's vehicle stopped near the victim's final location and that someone emerged from the vehicle to check to see whether the victim was dead. The petitioner testified at trial and admitted that he was present at the scene. He asserted, however, that he had no knowledge that Hampton was in possession of a gun until Hampton started shooting, that Hampton was the only shooter, and that the victim's perception of the events was impaired by drugs. The petitioner's testimony described a version of events casting Hampton as the lone criminal actor. According to the petitioner, the victim produced and lit up some "dust" (marijuana laced with embalming fluid), which she and Hampton shared in the car. After a stop at the petitioner's mother's house, where the petitioner and the victim had consensual, protected sex on the porch, the two males and the victim left in the car. Hampton then directed the petitioner to take them somewhere so he and the victim could have sex. The victim just sat there "in a daze." Hampton directed the petitioner to stop the car on Market Street, where he and the victim exited the car and went behind a building. When they emerged, the victim, who was holding her pants in hand, attempted to leave on foot rather than get back into the car. Hampton then pursued the victim. The petitioner moved the car near the Citgo station and then dozed off until he was awakened by a loud noise, which he later realized was a gunshot. When he saw that Hampton was firing a gun at the victim, the petitioner attempted to hit Hampton with the car but could not because he encountered a curb. After Hampton got into the car, the petitioner panicked and drove off.

In its closing argument, the state argued that the eyewitness accounts and the photographic evidence proved that the passenger got out of the car and shot the victim and that the driver—the petitioner—got out of the vehicle, looked at the victim lying on the ground, and got back into the car.

The court instructed the jury that, for all of the substantive charges except unlawful possession of a firearm, it could find that the petitioner had committed the crimes as a principal or an accessory, or could find him guilty on the basis of vicarious liability as Hampton's coconspirator under the Pinkerton doctrine. The jury found the petitioner guilty of all of the crimes charged. It found him guilty of the kidnapping charge as a principal or accessory and guilty of the assault and sexual assault charges as a coconspirator under Pinkerton .

"[T]o obtain a new trial on the basis of newly discovered evidence, the petitioner must establish that the newly proffered evidence (1) is actually newly discovered, (2) would be material in a new trial, (3) is not merely cumulative, and (4) would probably produce a different result in a new trial." Jones v. State , 328 Conn. 84, 92, 177 A.3d 534 (2018), citing Asherman v. State , 202 Conn. 429, 434, 521 A.2d 578 (1987). "This strict standard is meant to effectuate the underlying equitable principle that once a judgment is rendered it is to be considered final, and should not be disturbed by posttrial motions except for a compelling reason." (Internal quotation marks omitted.) Skakel v. State, 295 Conn. 447, 467, 991 A.2d 414 (2010). In his petition for a new trial, the petitioner alleged that there was newly discovered evidence in the form of (1) technological improvements to the security camera videotape that had been shown to the jury, which made clear that, contrary to the state's claim at trial, it was the vehicle's passenger (Hampton), not the driver (the petitioner), who exited the vehicle to approach the victim's body, and (2) significant impeachment evidence bearing on the credibility of Henderson, the lead detective, involving his posttrial arrest for official misconduct in connection with other cases. The petition also alleged as other reasonable cause for a new trial that the prosecutor had engaged in misconduct by not disclosing exculpatory evidence relating to the videotape, criminal charges brought against Henderson, and other matters, and by adducing false testimony from the victim.

In its decision denying the petition for a new trial, the court characterized the evidence against the petitioner as "overwhelming." It also pointed out that the petitioner's efforts to cast Hampton as the sole wrong-doer ignored the obvious and immovable impediment to the petitioner's exculpation under this theory, namely, the fact that the petitioner could have been convicted on the basis of accessorial or Pinkerton liability even if he, himself, had not assaulted or shot the victim. The trial court determined that both the videotape and the evidence related to Henderson failed to satisfy the Asherman test in multiple respects, and the court emphasized in particular that neither claim met the fourth prong of Asherman , as neither would probably produce a different result in a new trial. The court rejected the claims of prosecutorial misconduct on the grounds that the claims were undefined, unsupported by evidence, and/or lacking in merit. It similarly concluded that an issue not raised in the petition for a new trial but pressed at the related evidentiary hearing—purportedly suspicious circumstances surrounding the belated testing of the victim's blood sample that yielded negative results for the presence of drugs—would not affect the verdict.

As a threshold to our review of the merits, the petitioner must establish that the trial court abused its discretion in denying certification to appeal from the court's denial of his new trial petition. "A petitioner satisfies that burden by demonstrating: [1] that the issues are debatable among jurists of reason; [2] that a court could resolve the issues [in a different manner]; or [3] that the questions are adequate to deserve encouragement to proceed further." (Emphasis omitted; internal quotation marks omitted.) Seebeck v. State , supra, 246 Conn. at 534, 717 A.2d 1161 ; see id. (relying on framework adopted in Lozada v. Deeds , 498 U.S. 430, 431–32, 111 S. Ct. 860, 112 L. Ed. 2d 956 (1991), for analyzing certificate of probable cause to appeal under federal habeas corpus statute for petitions for certification to appeal under § 54-95 (a) ).

The petition for certification to appeal framed the issue warranting review broadly: "Whether the trial court erred in denying the petitioner's petition for a new trial." The petitioner's original appellate brief, in which he challenged the trial court's decision denying the new trial petition, focused exclusively on whether each piece of evidence offered in support of his new trial petition would have affected the verdict. The trial court's decision denying the petitioner's request for leave to file the petition for certification to appeal reiterated that court's view that the newly discovered evidence was not sufficiently material to have an effect on the verdict. We therefore similarly focus our discussion on whether the trial court abused its discretion by determining, in effect, that no court reasonably could conclude that the newly produced evidence would probably produce a different result in a new trial. "The burden of proving the probability of a different result is upon the [petitioner], and in determining that issue the trial court exercises a discretion [that] cannot be set aside unless its discretionary power has been abused." Johnson v. State , 172 Conn. 16, 17, 372 A.2d 138 (1976) ; cf. Jones v. State , supra, 328 Conn. at 87, 177 A.3d 534 (recognizing exception in which de novo review is appropriate when petition for new trial is decided by judge who did not preside over original trial and no fact-finding was necessary because both parties agreed that new evidence was fully credible). The petitioner must overcome a high hurdle to establish such an abuse of discretion. "To meet the fourth element of Asherman , [t]he [petitioner] must persuade the court that the new evidence he submits will probably , not merely possibly, result in a different verdict at a new trial .... It is not sufficient for him to bring in new evidence from which a jury could find him not guilty—it must be evidence [that] persuades the judge that a jury would find him not guilty." (Emphasis in original; internal quotation marks omitted.) Jones v. State , supra, at 93, 177 A.3d 534 ; see also Skakel v. State , supra, 295 Conn. at 467–68, 991 A.2d 414 ; cf. Henning v. Commissioner of Correction , 334 Conn. 1, 24–25, 219 A.3d 334 (2019) (discussing less stringent standard when newly discovered evidence involves knowing production of false testimony).

When examining the trial court's conclusion that the new evidence did not meet this standard, it is important to recognize that the trial judge, who also had presided over the petitioner's criminal trial, made an unchallenged determination that the evidence against the petitioner at the criminal trial was overwhelming. The judge who presided over the petitioner's habeas petition, although not having the opportunity to assess the credibility of the criminal trial witnesses, likewise characterized the state's case as a strong one. Those assessments presumably took into account the evidence previously recited, as well as evidence that the petitioner knew where the shotgun was hidden after the incident (a location to which both the petitioner and Hampton had access), evidence of sixty phone calls between the petitioner and Hampton on the day of the incident and the two days thereafter, and significant evidence demonstrating consciousness of guilt. The trial court's assessment also finds strong support in its observation that the petitioner's claim regarding Hampton's primary responsibility fails to exonerate him due to accessorial/ Pinkerton liability.

We have fully reviewed the record. The trial court did not clearly abuse its discretion in denying certification to appeal.

We begin with the technologically enhanced security camera videotape, which is indisputably clearer than the version offered at the criminal trial. That videotape displays more clearly the direction the vehicle was heading when it stopped and thereby also makes clearer that the passenger, and not the driver, emerged from the vehicle, presumably to approach the critically wounded victim. This fact is consistent with Henderson's testimony at the criminal trial about his observations of the still frames taken from the original videotape shown to the jury. It is inconsistent, however, with the testimony of the victim, as well the testimony of a security guard from a nearby building who had observed the events from a distance, that the petitioner/driver came out of the vehicle.

As the trial court noted in its decision denying the new trial petition, a similar claim regarding this evidence had previously been adjudicated in the habeas proceedings, albeit through the lens of the petitioner's claim of ineffective assistance of counsel. The habeas court's conclusion, upheld on appeal, was that no prejudice resulted from counsel's alleged failure to adequately investigate the videotape evidence to prove that the driver did not exit the vehicle. See Mitchell v. Commissioner of Correction , supra, 156 Conn. App. at 414, 420–21, 114 A.3d 168. That conclusion rested on the fact that the videotape and still frames did not capture the entire incident (no security cameras covered the area where the victim claimed that the sexual assaults occurred and the first shot was fired), the videotape and still frames were presented to the jury, and Henderson had testified that the still frames showed the passenger getting out of the car. Id., at 409–19, 114 A.3d 168. The habeas court also noted the strength of the state's case against the petitioner. Id., at 419–20, 114 A.3d 168.

To these observations we add that we would not characterize as meaningfully exculpatory the part of the incident that is captured in the enhanced videotape. The enhanced videotape shows that the petitioner brought the vehicle to a stop near the victim to allow Hampton to exit the vehicle, which gave Hampton the opportunity to inflict a fatal gunshot wound if the victim was not already dead or mortally wounded. The fundamental import of the evidence does not change: the petitioner wilfully and actively participated in the relevant criminal activity by stopping the vehicle to allow his passenger to ensure that the victim was dead.

We also are not persuaded that the enhanced videotape would have had a significant impeachment effect at trial. See generally Adams v. State , 259 Conn. 831, 839, 792 A.2d 809 (2002) ("[N]ew trials [typically] are not granted upon newly discovered evidence which discredits a witness unless the evidence is [both] vital to the issues and ... strong and convincing .... The rule restricting the right to a new trial when one is claimed on the basis of newly discovered evidence merely affecting the credibility of a witness is necessary because scarcely has there been an important trial ... [after which a] diligent search would not have discovered evidence [to impeach] some witness .... Without such a rule, there might never be an end to litigation." (Citation omitted; internal quotation marks omitted.)). Although the enhanced videotape could be used to impeach the testimony of the victim and the security guard that the driver exited the vehicle, it seems exceedingly unlikely that this discrepancy would have undermined the general credibility of either witness. At the time the victim was approached by whoever exited the vehicle, after all, she not only was suffering from the physical effects of life-threatening shotgun wounds, but also was attempting to observe her assailants’ actions without giving away that she was still alive. It is farfetched to think that the jury would have doubted other aspects of her testimony merely because she confused the passenger for the driver as the man who approached her to assess her condition after the shooting. The security guard's misperception of the identity of the person exiting the vehicle, likewise inconsequential, is most probably explained by the fact that the vehicle was stopped in the opposite travel lane, so that the passenger's side of the vehicle would be on the side where the driver normally would be. We are not persuaded that the trial court's findings and conclusions as to the videotape evidence are debatable among jurists of reason, that a court could have resolved this claim in a different manner, or that there are any questions that warrant further proceedings. The trial court did not abuse its discretion in denying certification to appeal with respect to this issue.

We next consider the newly discovered evidence of former Detective Henderson's posttrial arrest and conviction. In support of this claim, the petitioner cited Thomas v. State , 130 Conn. App. 533, 24 A.3d 12, cert. denied, 302 Conn. 945, 30 A.3d 2 (2011), in which the Appellate Court rejected a similar claim that newly discovered evidence of Henderson's arrest and conviction required a new trial in that case. According to Thomas , Henderson was arrested in 2006 and charged in a ten count information with larceny in the first degree, forgery in the second degree, fabricating physical evidence, and tampering with a witness. Id., at 537, 24 A.3d 12. He entered a plea of nolo contendere to one of court of forgery in the second degree. Id. The charges apparently arose from criminal activity dating back to 2000 involving a forgery scheme used by Henderson to obtain money intended to compensate confidential informants. Id., at 539, 24 A.3d 12.

In the present case, the petitioner raised two claims to explain how he was harmed by the state's failure to disclose evidence of Henderson's illegal conduct. In his petition, he contended that the evidence should have been made available to him for impeachment purposes to attack Henderson's credibility as a witness. At trial on the petition, he contended that the evidence supported his theory that Henderson had obtained a second blood sample from the victim, which was used to produce the negative toxicology test.

The trial court agreed that this evidence could have been used at the defendant's criminal trial to impeach Henderson's credibility but concluded that it was not probable that a different result would occur if this evidence was available. The court noted that Henderson had undertaken all but two activities relating to the defendant's case in the presence of others and that neither of those two activities had proved to play a material part in the petitioner's conviction. It further concluded that, because the petitioner's coconspirator, Hampton, was convicted at a trial that occurred after Henderson's crimes were made known, through the testimony of a different detective, it was all but certain that a similar substitution and result would occur in the petitioner's new trial. The trial court's disposition of the petitioner's claim as to the general impeachment effect of this evidence plainly was not an abuse of discretion.

The petitioner's other theory as to the potential effect of evidence of Henderson's arrest, relating to the detective's role involving the blood samples, requires some explanation. A blood sample was taken from the victim in 2003 as part of her rape kit. The kit was sealed and placed in evidence with the Hartford Police Department; no toxicology test was run at that time. In 2005, after the petitioner's criminal trial counsel sought a court order to direct the state forensic laboratory to perform a toxicology test on the blood sample, the victim signed a "Consent for Toxicology Screen." At the hearing on the request, the state's attorney acknowledged that the blood sample "probably ha[d] not been refrigerated" and "may not [have been] viable for testing purposes." After the court issued the order, defense counsel wrote to Henderson asking him to deliver the blood sample in the rape kit to the laboratory. The following day, Henderson signed the rape kit out of evidence. Forms from the forensic laboratory reflect that the laboratory received two vials of blood. The toxicology test detected no drugs or metabolites.

From these facts, the petitioner hypothesizes that the evidence of Henderson's criminal activity, if made known to the jury, could have resulted in a different outcome because it would have supported the petitioner's theory that the victim's perception was impaired from smoking "dust." To reach this conclusion, the petitioner relies on the following suppositions: (1) the 2003 blood sample was not viable for testing due to a lack of refrigeration, (2) had the sample been viable, it would have tested positive for the presence of the drugs, (3) the 2005 consent form was executed to obtain a second blood sample to ensure that the toxicology test would not detect drugs in the victim's blood, and (4) because Henderson delivered the two vials of blood to the laboratory and had been charged with (but not convicted of) fabricating evidence in an unrelated case, he had switched the 2005 blood sample for the 2003 sample. We are not persuaded. There are many reasons why the evidence regarding Henderson's arrest does not give rise to a reasonable probability of a different verdict on the basis of this theory. Two stand out. First, the trial court found that the record demonstrated that the sample that was tested was the same one that was part of the rape kit, and the petitioner has not pointed to anything in the record that indicates otherwise. Contrary to the petitioner's view, the state's attorney's casual reference at the court hearing to a singular "vial" of blood is not evidence that misconduct was afoot when two vials were delivered to the laboratory. Nor does the mere fact that the "Consent for Toxicology Screen" form executed by the victim authorized "the collection ... of blood samples" for the purpose of detecting the presence of drugs; the form's plural phrasing does not in any way tend to prove that the state used that consent to obtain a second sample. Second, there was compelling evidence from which the jury probably would have concluded that the victim's drug use, even if it had occurred, did not materially impair her perception. The victim admitted that she had no idea whether the marijuana given to her by the petitioner could have contained "dust" but also testified that she had not noticed any difference in how she felt after smoking the joint. When police officers arrived on the scene shortly after the incident, the victim provided them with the accurate color, make, and model of the petitioner's vehicle, accurate information that it was a rental car, and accurate information about the direction in which the vehicle left the scene. The emergency department physician who treated the victim upon her admission declined to order a toxicology test because the physician saw no clinical evidence that the victim was under the influence of drugs. The physician testified that the victim appeared alert and oriented, and the physician confirmed that impression through testing. The victim told two physicians at the hospital that she knew the person who had inflicted her injuries, and she specifically identified the petitioner as the perpetrator to the police as soon as her breathing tube was removed following surgery.

Under these circumstances, the trial court did not abuse its discretion in effectively concluding that no court would conclude that evidence of Henderson's arrest and conviction probably would yield a different result in a new trial.

The petitioner also sought a new trial on the ground that the state withheld exculpatory evidence (i.e., a Brady violation) and introduced false testimony from the victim. See State v. McCoy , 331 Conn. 561, 598, 206 A.3d 725 (2019) ("newly discovered Brady claims may ... be brought by way of a petition for a new trial"); see also In re Jonathan M. , 255 Conn. 208, 239, 764 A.2d 739 (2001) ("[t]he causes for which new trials may be granted ... are only such as show that the parties did not have a fair and full hearing at the first trial; and the words or for other reasonable cause, mean other causes of the same general character" (internal quotation marks omitted)). Specifically, the petitioner contended that the prosecution suppressed (1) selective portions of videotape and photographic evidence that would have been inconsistent with the victim's version of events, (2) materials produced by Angelsea Critical Evidence, the company hired by the state to assess the security camera video and still frames and to produce viewable copies, (3) Henderson's malfeasances that were occurring concurrently with his investigation of the defendant, (4) evidence relevant to whether a second blood sample was taken, and (5) the dismissal of charges pending against the victim in consideration for her testimony. The petitioner also contended that the prosecution presented false testimony from the victim regarding the petitioner's actions on Market Street.

To prevail on a Brady claim, the petitioner must show that the evidence at issue was material, in the sense that there is a reasonable probability that the result would have been different had the evidence been disclosed. See Demers v. State , 209 Conn. 143, 150, 161, 547 A.2d 28 (1988). "[A] conviction obtained by the knowing use of perjured testimony ... must be set aside if there is any reasonable likelihood that the false testimony could have affected the judgment of the jury." (Internal quotation marks omitted.) Henning v. Commissioner of Correction , supra, 334 Conn. at 25, 219 A.3d 334.

In its decision denying the new trial petition, the trial court concluded that all of the petitioner's prosecutorial impropriety claims failed because there was no evidence or no newly discovered evidence that would be material. With regard to the claims relating to the security camera footage, the court found that the prosecution had provided the defense with a viewable copy of the videotape, albeit belatedly, and the defense did not request a continuance to investigate it further. With regard to Henderson's misconduct, the court rejected the admissibility and materiality of evidence proffered by the petitioner to show that Henderson had been arrested in Massachusetts on domestic violence charges. With regard to the dismissal of charges against the victim, the court found that there was no evidence to support the petitioner's contention that the victim had received inducements to testify. It noted that the state had entered nolles on a domestic violence charge and a motor vehicle charge against the victim in November, 2003, before preparations for the petitioner's criminal trial began.

We conclude that the trial court did not abuse its discretion in concluding that none of the petitioner's prosecutorial impropriety claims warrants appellate review. There is nothing in the record to suggest that the trial court's findings and conclusions are debatable among jurists of reason, that a court could have resolved this claim in a different manner, or that there are any questions that deserve further proceedings. In addition to the findings and conclusions of the trial court, our previous discussion explains why most of the evidence at issue would not likely result in a verdict of not guilty. We also add, with respect to the nolles of charges against the victim, that it is undisputed that the victim identified the petitioner as one of her assailants shortly after she came out of surgery, well before there could have been any purported inducement to testify. See State v. Ouellette , 295 Conn. 173, 186–87, 989 A.2d 1048 (2010) (noting that whether defendant established necessary factual predicate to his claim that state's attorney did, in fact, promise to dismiss charges against witness as part of plea agreement "is a fact based claim to be determined by the trial court, subject only to review for clear error"). The trial court did not abuse its discretion in concluding that certification to appeal should be denied. Although we disagree with the Appellate Court's rationale for dismissing the petitioner's appeal, its decision may be affirmed on this alternative basis.

The judgment of the Appellate Court is affirmed.

In this opinion the other justices concurred.
