The defendant, Ray Boyd, appeals from the trial court's dismissal of his motion to correct an illegal sentence for lack of jurisdiction. The defendant, who was sentenced to fifty years imprisonment without parole in 1992 for a crime that he committed when he was seventeen years old, contends that he is entitled to resentencing on the basis of recent changes to juvenile sentencing law. We discussed this precise issue in State v. Delgado , 323 Conn. 801 , 151 A.3d 345 (2016), and our resolution of the defendant's appeal is controlled by our decision in that case. We affirm the trial court's dismissal of the defendant's motion to correct.

The following facts and procedural history are relevant to the present appeal. The defendant was convicted of murder in violation of General Statutes § 53a-54a and sentenced by the trial court, W. Hadden, J. , to a term of fifty years imprisonment with no opportunity for parole. On appeal, the Appellate Court affirmed the judgment of conviction. State v. Boyd , 36 Conn.App. 516 , 525, 651 A.2d 1313 , cert. denied, 232 Conn. 912 , 654 A.2d 356 , cert. denied, 516 U.S. 828 , 116 S.Ct. 98 , 133 L.Ed.2d 53 (1995). The facts underlying the defendant's conviction are set forth in that decision.

In 2013, the defendant filed a motion to correct his sentence pursuant to Practice Book § 43-22, 1 contending that a prison term that is equivalent to life imprisonment without parole constituted cruel and unusual punishment in violation of the eighth amendment to the United States constitution and article first, §§ 8 and 9, of the Connecticut constitution. 2 The defendant further argued that his sentence was illegal because he had not been given a meaningful opportunity for release from prison, and that the sentence had been imposed in an illegal manner because he was not afforded an individualized sentencing hearing at which the court considered specific mitigating factors associated with his young age at the time of the crime of which he was convicted. See Miller v. Alabama , 567 U.S. 460 , 132 S.Ct. 2455 , 2469, 183 L.Ed.2d 407 (2012) (requiring sentencing court to consider youth related mitigating factors when imposing sentence of life imprisonment without parole); State v. Riley , 315 Conn. 637 , 658-59, 110 A.3d 1205 (2015) (sentencing court must consider age related evidence in mitigation when deciding whether to irrevocably sentence juvenile offender to term of life imprisonment, or equivalent, without parole), cert. denied, --- U.S. ----, 136 S.Ct. 1361 , 194 L.Ed.2d 376 (2016) ; see also Casiano v. Commissioner of Correction , 317 Conn. 52 , 62, 115 A.3d 1031 (2015) (sentencing considerations that were identified in Miller apply retroactively in collateral proceedings), cert. denied sub nom. Semple v. Casiano , --- U.S. ----, 136 S.Ct. 1364 , 194 L.Ed.2d 376 (2016). The trial court, Clifford, J. , did not reach the merits of the motion to correct but dismissed the motion for lack of jurisdiction, from which dismissal the defendant appeals. 3 In the present case, as in Delgado , we affirm the trial court's dismissal of the defendant's motion to correct for lack of jurisdiction. As we explained in Delgado , an allegation that a sentence is illegal or was imposed in an illegal manner is a necessary predicate to a trial court's jurisdiction to correct a sentence. See State v. Delgado , supra, 323 Conn. at 812 , 151 A.3d 345 . When the defendant in the present case filed his motion to correct, he was serving a sentence that was equivalent to life imprisonment and he was not eligible for parole. As a result, he could raise a colorable claim that his sentence was illegal or imposed in an illegal manner on the ground that the trial court had failed to consider youth related factors as required by Miller. Following the enactment of No. 15-84 of the 2015 Public Acts (P.A. 15-84), 4 however, the defendant is now eligible for parole and can no longer claim that he is serving a sentence of life imprisonment, or its equivalent, without parole. In considering this issue in Delgado , we explained that "[t]he eighth amendment, as interpreted by Miller , does not prohibit a court from imposing a sentence of life imprisonment with the opportunity for parole for a juvenile homicide offender, nor does it require the court to consider the mitigating factors of youth before imposing such a sentence. ... Rather, under Miller , a sentencing court's obligation to consider youth related mitigating factors is limited to cases in which the court imposes a sentence of life, or its equivalent, without parole. ... As a result, the defendant's sentence no longer falls within the purview of Miller, Riley and Casiano , which require consideration of youth related mitigating factors only if the sentencing court imposes a sentence of life without parole." (Citations omitted; emphasis in original.) Id., at 810-11 , 151 A.3d 345 .

In sum, because Miller, Riley and Casiano do not require a trial court to consider any particular mitigating factors associated with a juvenile's young age before imposing a sentence that includes an opportunity for parole, the defendant can no longer allege, after the enactment of P.A. 15-84, that his sentence was imposed in an illegal manner on the ground that the trial court failed to take these factors into account. We therefore conclude that the defendant has not raised a colorable claim of invalidity that, if decided in his favor, would require resentencing. See id., at 812-13 , 151 A.3d 345 . In the absence of such an allegation, the trial court does not have jurisdiction over the motion to correct.

The trial court's dismissal of the defendant's motion to correct an illegal sentence is affirmed.

In this opinion the other justices concurred.
