In a recent trilogy of cases, the United States Supreme Court fundamentally altered the legal landscape for the sentencing of juvenile offenders1 to comport with the ban on cruel and unusual punishment under the eighth amendment to the federal constitution. The court first barred capital punishment for all juvenile offenders; Roper v. Simmons, 543 U.S. 551, 575, 125 S. Ct. 1183, 161 L. Ed. 2d 1 (2005); and then barred life imprisonment without the possibility of parole for juve- nile nonhomicide offenders. Graham v. Florida, 560 U.S. 48, 79–80, 130 S. Ct. 2011, 176 L. Ed. 2d 825 (2010). Most recently, in Miller v. Alabama, U.S. , 132 S. Ct. 2455, 2460, 183 L. Ed. 2d 407 (2012), the court held that mandatory sentencing schemes that impose a term of life imprisonment without parole on juvenile homicide offenders, thus precluding consideration of the offender’s youth as mitigating against such a severe punishment, violate the principle of proportionate pun- ishment under the eighth amendment. Miller did not specifically address the constitutional parameters of when a life sentence without parole may be imposed in the exercise of the sentencing authority’s discretion on a juvenile homicide offender. The present case requires us to consider this question. The defendant, Ackeem Riley, was seventeen years old when he committed homicide and nonhomicide offenses for which the trial court imposed, in the exer- cise of its discretion, a total effective sentence of 100 years imprisonment. The defendant has no possibility of parole before his natural life expires. In his certified appeal to this court, the defendant claims that his sen- tence and the procedures under which it was imposed violate Graham and Miller, and, hence, the eighth amendment. Specifically, the defendant contends that: (1) Miller required the trial court to consider his youth and circumstances attendant to his youth as mitigating against the functional equivalent to a life sentence with- out parole when exercising its sentencing discretion; and (2) if the trial court imposes the functional equiva- lent to a life sentence in the exercise of its discretion, Graham requires that he be afforded a subsequent opportunity to obtain release based on his demon- strated maturity and rehabilitation. We agree with the defendant’s Miller claim. There- fore, he is entitled to a new sentencing proceeding at which the court must consider as mitigation the defen- dant’s age at the time he committed the offenses and the hallmarks of adolescence that Miller deemed consti- tutionally significant when a juvenile offender is subject to a potential life sentence. We decline, however, to address the defendant’s Graham claim. As we explain later in this opinion, the legislature has received a sen- tencing commission’s recommendations for reforms to our juvenile sentencing scheme to respond to the dic- tates of Graham and Miller. Therefore, in deference to the legislature’s authority over such matters and in light of the uncertainty of the defendant’s sentence upon due consideration of the Miller factors, we conclude that it is premature to determine whether it would violate the eighth amendment to preclude any possibility of release when a juvenile offender receives a life sentence. We begin with a brief overview of the facts that the jury reasonably could have found and the procedural history of this case. In November, 2006, when the defen- dant was seventeen years old, he participated in a drive- by shooting into a crowd that left an innocent sixteen year old dead and two other innocent bystanders, ages thirteen and twenty-one, seriously injured. The defen- dant and his accomplice thought that someone respon- sible for a gang related shooting the previous week was at the scene. The defendant’s identity as one of the perpetrators was corroborated by his involvement in an incident two months after the crimes at issue in which a firearm was discharged that matched the weapon used in the 2006 shootings. A jury convicted the defendant of one count of murder in violation of General Statutes §§ 53a-54a (a) and 53a-8, two counts of attempt to commit murder in violation of General Statutes §§ 53a-49 (a) (2) and 53a-54a (a), two counts of assault in the first degree in violation of General Statutes §§ 53a-59 (a) (5) and 53a-8, and one count of conspiracy to commit murder in violation of General Statutes §§ 53a-48 (a) and 53a-54a (a). The murder con- viction exposed the defendant to a potential sentence of twenty-five to sixty years imprisonment, with no possibility of parole. See General Statutes §§ 53a-35a (2), 53a-35b and 54-125a (b) (1) (E). The other convic- tions exposed him to sentences ranging from one year imprisonment to twenty years imprisonment. The trial court ultimately imposed a total effective sentence of 100 years imprisonment. It is undisputed that this sentence is the functional equivalent to life without the possibility of parole.2 See State v. Riley, 140 Conn. App. 1, 3 n.2, 58 A.3d 304 (2013). In stating its basis for imposing this sentence, the trial court made no reference to the defendant’s age at the time he com- mitted the offenses. After the trial court rendered judg- ment in the present case in 2009, the United States Supreme Court issued its decision in Miller. In his appeal to the Appellate Court, the defendant contended that his sentence and the procedure under which it was imposed violated his rights under the eighth and fourteenth amendments to the federal consti- tution. Id., 4, 10 and n.7. A majority of the Appellate Court rejected these contentions. Id., 4. The majority concluded that Miller requires only that a defendant be afforded the opportunity to present mitigating evidence, including evidence relating to his age, and that the court be permitted to impose a lesser sentence than life with- out parole after considering any such evidence. Id., 10, 14–16. It determined that Connecticut’s sentencing scheme comported with these requirements. Id., 18. The majority further concluded that the trial court in the present case had in fact considered many of the factors identified as relevant in Miller before imposing the defendant’s sentence. Id., 19–21. In his dissenting opin- ion, Judge Borden disagreed with each of these determi- nations and concluded that the defendant was entitled to a new sentencing proceeding. Id., 23–40. Judge Bor- den further opined that, if a trial court determines that a life sentence is appropriate after giving due weight to the offender’s youth, Graham requires the court to provide for a ‘‘second look,’’ i.e., a meaningful opportu- nity for the juvenile offender to obtain release based on demonstrated maturity and rehabilitation. Id., 39–40. In his certified appeal to this court, the defendant contends that the Appellate Court majority was incor- rect as a matter of law and fact. Specifically, he con- tends that the sentencing procedure and the sentence itself failed to conform to the dictates of Miller and Graham. For the reasons that follow, we agree that the defendant is entitled to a new sentencing proceeding that follows the dictates of Miller. I THE UNITED STATES SUPREME COURT’S TRILOGY The eighth amendment to the United States constitu- tion provides: ‘‘Excessive bail shall not be required, nor excessive fines imposed, nor cruel and unusual punishments inflicted.’’ This provision is applicable to the states through the fourteenth amendment. See Fur- man v. Georgia, 408 U.S. 238, 239, 92 S. Ct. 2726, 33 L. Ed. 2d 346 (1972). ‘‘[T]he [e]ighth [a]mendment guaran- tees individuals the right not to be subjected to exces- sive sanctions. The right flows from the basic precept of justice that punishment for crime should be gradua- ted and proportioned to [the] offense.’’ (Internal quota- tion marks omitted.) Roper v. Simmons, supra, 543 U.S. 560. Although the unique aspects of adolescence had long been recognized in the Supreme Court’s jurisprudence,3 it was not until the trilogy of Roper, Graham, and Miller that the court held that youth and its attendant charac- teristics have constitutional significance for purposes of assessing proportionate punishment under the eighth amendment. Cf. Stanford v. Kentucky, 492 U.S. 361, 382–405, 109 S. Ct. 2969, 106 L. Ed. 2d 306 (1989) (Bren- nan, J., dissenting) (criticizing majority’s failure to con- sider principle of proportionate punishment in determining that death penalty may be applied to per- sons who committed capital crime between ages of sixteen and eighteen), overruled in part by Roper v. Simmons, 543 U.S. 551, 574, 125 S. Ct. 1183, 161 L. Ed. 2d 1 (2005). Because Roper and Graham lay the foundation for Miller, we begin with a brief overview of those cases. A Roper Christopher Simmons was seventeen years old when he planned and carried out the brutal murder of a stranger. Roper v. Simmons, supra, 543 U.S. 556–57. The state of Missouri challenged the Missouri Supreme Court’s decision setting aside Simmons’ sentence of death and resentencing him to life imprisonment with- out eligibility for parole due to his age when he commit- ted the offense. Id., 559–60. The United States Supreme Court agreed with the state court that the execution of a person who was between the ages of sixteen and eighteen when he committed a capital crime constituted disproportionate punishment in violation of the eighth amendment.4 Id., 555, 568; see Thompson v. Oklahoma, 487 U.S. 815, 838, 108 S. Ct. 2687, 101 L. Ed. 2d 702 (1988) (plurality) (concluding that execution of person who was under age of sixteen at time offense was com- mitted violates eighth and fourteenth amendments). In reaching its conclusion, the court relied upon its prior case law recognizing the unique characteristics of juveniles and scientific evidence regarding differences between adult and juvenile psychological development that explained these characteristics. Roper v. Simmons, supra, 543 U.S. 569–71. This evidence demonstrated that a juvenile’s less developed character, maturity and impulse control affect decision making and apprecia- tion of risk, and that a juvenile’s poor decisions did not necessarily portend how the offender might act upon achieving maturation. Id., 569–70. Because of a juve- nile’s diminished culpability, the court concluded that the two penological justifications for the death penalty, retribution and deterrence, applied with lesser force to them than to adults. Id., 571. The court suggested that, ‘‘[t]o the extent the juvenile death penalty might have residual deterrent effect, it is worth noting that the punishment of life imprisonment without the possibility of parole is itself a severe sanction, in particular for a young person.’’ Id., 572. The court ultimately determined that a categorical ban on executing juvenile offenders was required. Id., 573. It reasoned that ‘‘[a]n unacceptable likelihood exists that the brutality or cold-blooded nature of any particular crime would overpower mitigating argu- ments based on youth as a matter of course, even where the juvenile offender’s objective immaturity, vulnerabil- ity, and lack of true depravity should require a sentence less severe than death.’’ Id. In response to an argument that a rare case might exist wherein the juvenile demon- strated sufficient maturity and depravity to warrant a death sentence, the court pointed out that ‘‘[i]t is diffi- cult even for expert psychologists to differentiate between the juvenile offender whose crime reflects unfortunate yet transient immaturity, and the rare juve- nile offender whose crime reflects irreparable corrup- tion.’’ Id. Accordingly, the court held that ‘‘[w]hen a juvenile offender commits a heinous crime, the [s]tate can exact forfeiture of some of the most basic liberties, but the [s]tate cannot extinguish his life and his poten- tial to attain a mature understanding of his own human- ity.’’ (Internal quotation marks omitted.) Id., 573–74. B Graham Five years later, the court considered whether a sen- tence of life imprisonment without parole is dispropor- tionate punishment for a juvenile offender who committed a nonhomicide crime. Graham v. Florida, supra, 560 U.S. 52–53, 59. Terrance Jamar Graham was seventeen years old when he violated his probation on charges including armed burglary by committing other crimes six months later. Id., 53–55. Reasoning that the defendant had an escalating pattern of criminal con- duct, the trial court imposed the maximum sentence permitted by law—life imprisonment. Id., 57. Parole was unavailable under state law. Id. The First District Court of Appeal of Florida concluded that Graham’s sentence was not grossly disproportionate to his crimes. Id., 58. The United States Supreme Court cate- gorically rejected that conclusion. Id., 67–75. The court’s reasoning in Graham largely expanded upon the analytic blueprint of Roper. Graham relied on further developments in psychology and brain sci- ence that supported the foundational determination in Roper regarding the lesser culpability of juvenile offend- ers. Id., 68. Graham analogized the severity of a sen- tence of life without the possibility of parole for a juvenile offender to capital punishment: ‘‘[F]or a juve- nile defendant, this sentence means denial of hope; it means that good behavior and character improvement are immaterial; it means that whatever the future might hold in store for the mind and spirit of [the convict], he will remain in prison for the rest of his days.’’ (Internal quotation marks omitted.) Id., 70. The court reasoned that a life sentence without parole, the most severe punishment permitted by law for a juvenile offender, was particularly disproportionate in light of prior cases ‘‘recogniz[ing] that defendants who do not kill, intend to kill, or foresee that life will be taken are categorically less deserving of the most serious forms of punishments than are murderers.’’ Id., 69. Thus, the juvenile nonhomi- cide offender has a ‘‘twice diminished moral culpability’’ when compared to an adult murderer. Id. In addition to the legitimate penological goals of retri- bution and deterrence that Roper had found lacking in applying the death penalty to juvenile offenders, the court found that other legitimate goals for punish- ment—rehabilitation and incapacitation—also were rendered largely ineffective due to the unique character- istics of juvenile offenders. Id., 71–74. Like Roper, Gra- ham questioned the sentencer’s ability to predict whether a juvenile would be a risk to society for the rest of his life in light of his greater capacity for change than an adult offender. The court noted that, ‘‘[e]ven if the [s]tate’s judgment that Graham was incorrigible were later corroborated by prison misbehavior or fail- ure to mature, the sentence was still disproportionate because that judgment was made at the outset. A life without parole sentence improperly denies the juvenile offender a chance to demonstrate growth and matu- rity.’’ Id., 73. In light of these considerations, the court held: ‘‘A [s]tate is not required to guarantee eventual freedom to a juvenile offender convicted of a nonhomicide crime. What the [s]tate must do, however, is give defendants like Graham some meaningful opportunity to obtain release based on demonstrated maturity and rehabilita- tion. . . . The [e]ighth [a]mendment does not foreclose the possibility that persons convicted of nonhomicide crimes committed before adulthood will remain behind bars for life. It does forbid [s]tates from making the judgment at the outset that those offenders never will be fit to reenter society.’’ Id., 75. C Miller Roper and Graham followed a strand of the court’s proportionality jurisprudence under which the court adopted categorical bans on sentencing practices for particular groups of offenders ‘‘based on mismatches between the culpability of [that] class of offenders and the severity of a penalty.’’ Miller v. Alabama, supra, 132 S. Ct. 2463. Another strand of proportionality juris- prudence, applied in death penalty cases, required indi- vidualized sentencing procedures wherein the mitigating characteristics of a defendant and the details of the offense must be considered. See, e.g., Eddings v. Oklahoma, 455 U.S. 104, 115, 102 S. Ct. 869, 71 L. Ed. 2d 1 (1982) (evidence of violent family background and emotional disturbance is ‘‘particularly relevant’’ mitigat- ing circumstance that must be considered before impos- ing death penalty on sixteen year old). In light of Graham’s analogy between life without parole and the death penalty, the court in Miller concluded that both strands of jurisprudence were implicated in eighth amendment challenges by two offenders who were four- teen years old when they committed murder, an offense for which state law mandated life without parole. Miller v. Alabama, supra, 2460, 2464. The court concluded that such a scheme violates the eighth amendment because it ‘‘prevents those meting out punishment from considering a juvenile’s ‘lessened culpability’ and greater ‘capacity for change,’ Graham v. Florida, [supra, 560 U.S. 48], and runs afoul of our cases’ require- ment of individualized sentencing for defendants facing the most serious penalties.’’ Miller v. Alabama, supra, 2460. The court explained that ‘‘Roper and Graham estab- lish that children are constitutionally different from adults for purposes of sentencing. . . . Those cases relied on three significant gaps between juveniles and adults. First, children have a lack of maturity and an underdeveloped sense of responsibility, leading to reck- lessness, impulsivity, and heedless risk-taking. . . . Second, children are more vulnerable . . . to negative influences and outside pressures, including from their family and peers; they have limited contro[l] over their own environment and lack the ability to extricate them- selves from horrific, crime-producing settings. . . . And third, a child’s character is not as well formed as an adult’s; his traits are less fixed and his actions less likely to be evidence of irretrievabl[e] deprav[ity].’’ (Citations omitted; internal quotation marks omitted.) Id., 2464. The court emphasized that these two decisions rested not only on common sense, but also on science and social science: ‘‘In Roper, we cited studies showing that [o]nly a relatively small proportion of adolescents who engage in illegal activity develop entrenched patterns of problem behavior. . . . And in Graham, we noted that developments in psychology and brain science con- tinue to show fundamental differences between juvenile and adult minds—for example, in parts of the brain involved in behavior control. . . . We reasoned that those findings—of transient rashness, proclivity for risk, and inability to assess consequences—both les- sened a child’s moral culpability and enhanced the pros- pect that, as the years go by and neurological development occurs, his deficiencies will be reformed.’’ (Citations omitted; footnote omitted; internal quotation marks omitted.) Id., 2464–65. Miller further under- scored the connection between these findings and the diminished penological justifications for imposing the harshest sentences on juvenile offenders ‘‘even when they commit terrible crimes.’’ Id., 2465. Despite the distinction the court in Graham drew between homicide and nonhomicide offenders, the court in Miller determined that the reasoning of Gra- ham applied with equal force to any juvenile life sen- tence without parole: ‘‘[N]one of what [Graham] said about children . . . is crime-specific. . . . Graham’s reasoning implicates any life-without-parole sentence imposed on a juvenile, even as its categorical bar relates only to nonhomicide offenses. Most fundamentally, Graham insists that youth matters in determining the appropriateness of a lifetime of incarceration without the possibility of parole. . . . An offender’s age, we made clear in Graham, is relevant to the [e]ighth [a]mendment, and so criminal procedure laws that fail to take defendants’ youthfulness into account at all would be flawed.’’ (Citation omitted; internal quotation marks omitted.) Id., 2465–66. A mandatory sentence of life without parole for a juvenile offender, however, contravenes this reasoning insofar as it ‘‘precludes consideration of his chronologi- cal age and its hallmark features—among them, imma- turity, impetuosity, and failure to appreciate risks and consequences. It prevents taking into account the fam- ily and home environment that surrounds him—and from which he cannot usually extricate himself—no matter how brutal or dysfunctional. It neglects the cir- cumstances of the homicide offense, including the extent of his participation in the conduct and the way familial and peer pressures may have affected him. Indeed, it ignores that he might have been charged and convicted of a lesser offense if not for incompetencies associated with youth—for example, his inability to deal with police officers or prosecutors (including on a plea agreement) or his incapacity to assist his own attorneys. . . . And finally, this mandatory punish- ment disregards the possibility of rehabilitation even when the circumstances most suggest it.’’ (Citations omitted.) Id., 2468. Perhaps most significantly for our purposes, the court in Miller summarized its holding as follows: ‘‘[T]he [e]ighth [a]mendment forbids a sentencing scheme that mandates life in prison without possibility of parole for juvenile offenders. . . . By making youth (and all that accompanies it) irrelevant to imposition of that harshest prison sentence, such a scheme poses too great a risk of disproportionate punishment. Because that holding is sufficient to decide these cases, we do not consider [the petitioners’] alternative argument that the [e]ighth [a]mendment requires a categorical bar on life without parole for juveniles, or at least for those [fourteen] and younger. But given all we have said in Roper, Graham, and this decision about children’s diminished culpabil- ity and heightened capacity for change, we think appro- priate occasions for sentencing juveniles to this harshest possible penalty will be uncommon. That is especially so because of the great difficulty we noted in Roper and Graham of distinguishing at this early age between the juvenile offender whose crime reflects unfortunate yet transient immaturity, and the rare juve- nile offender whose crime reflects irreparable corrup- tion. . . . Although we do not foreclose a sentencer’s ability to make that judgment in homicide cases, we require it to take into account how children are differ- ent, and how those differences counsel against irrevoca- bly sentencing them to a lifetime in prison.’’ (Citations omitted; internal quotation marks omitted.) Id., 2469. II IMPORT OF MILLER FOR DISCRETIONARY SENTENCING SCHEMES The parties dispute whether Miller extends beyond mandatory sentencing schemes. The state reads Miller narrowly in light of its emphasis on the defects inherent in a mandatory scheme. The defendant reads Miller broadly in light of its rationale. We conclude that the state’s view of Miller is unduly restrictive. We read the import of Miller as impacting two aspects of sentencing: (1) that a lesser sentence than life without parole must be available for a juvenile offender; and (2) that the sentencer must consider age related evidence as mitiga- tion when deciding whether to irrevocably sentence juvenile offenders to a lifetime in prison. Accordingly, for the reasons set forth subsequently in this opinion, we hold that the dictates set forth in Miller may be violated even when the sentencing authority has discre- tion to impose a lesser sentence than life without parole if it fails to give due weight to evidence that Miller deemed constitutionally significant before determining that such a severe punishment is appropriate. We begin by acknowledging that Miller is replete with references to ‘‘mandatory’’ life without parole and like terms. Nonetheless, the Supreme Court’s incremen- tal approach to assessing the proportionality of juvenile punishment counsels against viewing these cases through an unduly myopic lens. Roper contained lan- guage indicating that life imprisonment without parole would be a constitutionally permissible punishment for a juvenile offender when striking down the juvenile death penalty. See Roper v. Simmons, supra, 543 U.S. 572; see also State v. Allen, 289 Conn. 550, 581–82, 958 A.2d 1214 (2008) (agreeing with authority from other jurisdictions concluding that life sentence without parole for juvenile offender is permissible under Roper). Yet, the court in Graham relied on the reasoning in Roper to conclude that imposing such a punishment on juvenile nonhomicide offenders violates eighth amend- ment proportionality principles. See Graham v. Flor- ida, supra, 560 U.S. 68, 71–73. Similarly, Graham contained language distinguishing between nonhomi- cide and homicide offenses when striking down life sentences without parole for nonhomicide offenders. See id., 69. Yet, the court in Miller underscored that nothing Graham had noted about juvenile characteris- tics was crime specific when the court extended the reasoning of Graham to preclude mandatory life sen- tences without parole. Miller v. Alabama, supra, 132 S. Ct. 2465. Indeed, while carefully limiting its holding to mandatory sentences, Miller expressly reserved judg- ment on whether all juvenile life sentences without parole would run afoul of the eighth amendment. Id. Accordingly, the court’s approach in this arena counsels us to examine the logical implications of its reasoning in these decisions. Three aspects of Miller, when read in light of Roper and Graham, demonstrate that the decision logically reaches beyond its core holding. First, Roper, Graham and Miller emphasized their reliance on an ever growing body of authoritative evidence establishing constitu- tionally significant differences between adult and juve- nile brains. See id., 2464–65 n.5 (‘‘[t]he evidence presented to us in these cases indicates that the science and social science supporting Roper’s and Graham’s conclusions have become even stronger’’). In reliance on this evidence, the court in Miller explained that ‘‘[m]ost fundamentally, Graham insists that youth mat- ters in determining the appropriateness of a lifetime of incarceration without the possibility of parole.’’ (Emphasis added.) Id., 2465. Consistent with that dic- tate, the court in Miller held that it would ‘‘require [the sentencer] to take into account how children are different, and how those differences counsel against irrevocably sentencing them to a lifetime in prison.’’ (Emphasis added.) Id., 2469. This mandate logically would extend to a discretionary sentencing scheme. Second, in Miller, the court expressed its confidence that, once the sentencing authority considers the miti- gating factors of the offender’s youth and its attendant circumstances, ‘‘appropriate occasions for sentencing juveniles to this harshest possible penalty will be uncommon.’’ Id. This language suggests that the mitigat- ing factors of youth establish, in effect, a presumption against imposing a life sentence without parole on a juvenile offender that must be overcome by evidence of unusual circumstances. This presumption logically would extend to discretionary schemes that authorize such a sentence. Third, Miller and Graham analogized the harshness of a life sentence without parole for a juvenile to the death penalty. See id., 2466; Graham v. Florida, supra, 560 U.S. 69–71. This penalty is no less harsh if imposed pursuant to an exercise of discretion. We also find instructive the approach of other juris- dictions to the question of what Miller demands. Although there is a split of authority among courts that have considered whether Miller applies to discretionary sentencing schemes,5 we find most telling the response of those jurisdictions whose mandatory sentencing schemes were rendered unconstitutional by Miller. Many of these jurisdictions have reformed their sen- tencing procedures to require the sentencing court to consider those youth related factors that Miller identi- fied as constitutionally relevant mitigation. See, e.g., Mich. Comp. Laws § 769.25 (6) (2014) (‘‘If the prosecut- ing attorney files a motion [seeking a sentence of life imprisonment without parole], the court shall conduct a hearing on the motion as part of the sentencing pro- cess. At the hearing, the trial court shall consider the factors listed in Miller [v.] Alabama, [supra, 132 S. Ct. 2455], and may consider any other criteria relevant to its decision, including the individual’s record while incarcerated.’’); Neb. Rev. Stat. § 28-105.02 (2) (Supp. 2013) (requiring court to consider juvenile offender’s age and numerous other youth related factors); Wash. Rev. Code § 10.95.030 (3) (b) (2014) (‘‘[i]n setting a minimum term, the court must take into account miti- gating factors that account for the diminished culpabil- ity of youth as provided in Miller v. Alabama, [supra, 2455] including, but not limited to, the age of the individ- ual, the youth’s childhood and life experience, the degree of responsibility the youth was capable of exer- cising, and the youth’s chances of becoming rehabili- tated’’); W. Va. Code Ann. § 61-11-23 (c) (LexisNexis 2014) (requiring court to consider juvenile offender’s age and numerous other youth related factors); but see, e.g., State v. Ali, 855 N.W.2d 235, 257 (Minn. 2014) (sentencer must hold evidentiary hearing to consider Miller mitigation factors ‘‘upon request and with the assistance of counsel’’). In addition, several jurisdic- tions have required the sentencing court to state on the record the basis for a conclusion that life imprisonment without parole is an appropriate sentence, despite miti- gating factors relating to the offender’s youth. See, e.g., Mich. Comp. Laws § 769.25 (7) (2014); N.C. Gen. Stat. Ann. § 15A-1340.19C (a) (LexisNexis 2013); 18 Pa. Cons. Stat. Ann. § 1102.1 (d) (7) (West Cum. Supp. 2014); see also Sen v. State, 301 P.3d 106, 127 (Wyo. 2013) (‘‘in exercising its discretion with regard to a determination as to parole eligibility, the district court must set forth specific findings supporting a distinction between ‘the juvenile offender whose crime reflects unfortunate yet transient immaturity, and the rare juvenile offender whose crime reflects irreparable corruption’ ’’). For the foregoing reasons, we conclude that Miller does not stand solely for the proposition that the eighth amendment demands that the sentencer have discretion to impose a lesser punishment than life without parole on a juvenile homicide offender. Rather, Miller logically indicates that, if a sentencing scheme permits the impo- sition of that punishment on a juvenile homicide offender, the trial court must consider the offender’s ‘‘chronological age and its hallmark features’’ as mitigat- ing against such a severe sentence. Miller v. Alabama, supra, 132 S. Ct. 2468. As the court in Miller explained, those features include: ‘‘immaturity, impetuosity, and failure to appreciate risks and consequences’’; the offender’s ‘‘family and home environment’’ and the offender’s inability to extricate himself from that envi- ronment; ‘‘the circumstances of the homicide offense, including the extent of [the offender’s] participation in the conduct and the way familial and peer pressures may have affected him’’; the offender’s ‘‘inability to deal with police officers or prosecutors (including on a plea agreement) or his incapacity to assist his own attor- neys’’; and ‘‘the possibility of rehabilitation . . . .’’6 Id. We note that, following the decision in Miller, our state’s presentence report has incorporated these fac- tors as required subjects of investigation and reporting. See State of Connecticut, Judicial Branch, Court Sup- port Services Division, ‘‘Policies and Procedures,’’ Pol- icy 4.31, effective August 15, 2013, pp. 11, 14–22. In addition to these factors specific to the individual juve- nile offender, the report must ‘‘note any scientific and psychological evidence showing the differences between a child’s (a person under the age of [eighteen]) brain development and an adult’s brain development . . . .’’ Id., p. 22. Although it appears from the report form that the Court Support Services Division intends to provide courts with information on this subject at some point in the future, in the interim, we direct our trial courts to the evidence that Roper, Graham, and Miller credited as authoritative on this subject. To con- form to Miller’s mandate and our rules of practice; see Practice Book § 43-10; the record must reflect that the trial court has considered and given due mitigating weight to these factors in determining a proportion- ate punishment. III APPLICATION OF MILLER TO THE PRESENT CASE By statute and the rules of practice, our trial courts must consider the information in the presentence report before imposing sentence. See General Statutes § 54- 91a (a); Practice Book §§ 43-3 and 43-10. In 2009, when the court imposed sentence in the present case, the presentence report did not require information specific to juvenile offenders. The report generically required information regarding, inter alia, ‘‘the circumstances of the offense . . . and the criminal record, social history and present condition of the defendant.’’ General Stat- utes § 54-91a (c). The court was required at that time, and still is today, to hear from all parties and to state on the record the reasons for the sentence imposed. Practice Book § 43-10 (6). Accordingly, nothing in our sentencing scheme specifically required the trial court in the present case to consider, let alone give mitigating weight to, the defendant’s age at the time of the offense or the hallmarks of youth. Nor does the record in the present case reflect, as the state contends, that the trial court adequately con- sidered the factors identified in Miller. In the entire sentencing proceeding, only defense counsel made an oblique reference to age. Defense counsel commented, ‘‘[y]ou can see that, obviously, [the defendant is] a young man’’—a remark that appears to refer to the defendant’s age at the time of sentencing—and asked the court to consider the defendant’s age. The defendant was then almost twenty years old. Although the undated presen- tence report reflected the defendant’s date of birth and age (nineteen) at the time the report was prepared, it did not address the defendant’s immaturity, impetuos- ity, and failure to appreciate risks and consequences. Nor did it address the science that establishes such factors as generally applicable. The main thrust of the court’s comments at sentenc- ing related to the innocence of the victims and the choice made by the defendant to commit these sense- less crimes. Before imposing a sentence under which the defendant would undoubtedly die in prison, the court characterized the presentence report as reflecting a life that was ‘‘pretty unremarkable.’’ The court made no mention of facts in the presentence report that might reflect immaturity, impetuosity, and failure to appreci- ate risks and consequences. For example, there was no mention of the fact that the defendant was reported to have a five year old child, which meant that he had fathered the child at or before the age of fourteen. Instead, the court noted: ‘‘I have very little sense of the type of person [the defendant] is except for what he did on this day and for that that’s what I have to sentence him for.’’ Accordingly, the record does not clearly reflect that the court considered and gave mitigating weight to the defendant’s youth and its hallmark fea- tures when considering whether to impose the func- tional equivalent to life imprisonment without parole. Therefore, the defendant is entitled to a new sentenc- ing proceeding that conforms to the dictates of Miller. Both the defendant and the state are free to present additional evidence at this new proceeding. IV WHETHER THE DEFENDANT’S SENTENCE VIOLATED GRAHAM As we previously explained, Graham precludes the sentencer from determining at the outset that a juvenile nonhomicide offender is beyond rehabilitation, thus requiring that such offenders be afforded a meaningful opportunity to obtain release based on demonstrated maturity and rehabilitation if sentenced to life imprison- ment. Graham v. Florida, supra, 560 U.S. 75. The court left it to the states ‘‘to explore the means and mecha- nisms for compliance’’; id.; with this so-called ‘‘second look’’ opportunity. State v. Riley, supra, 140 Conn. App. 22 (Borden, J., dissenting); State v. Null, 836 N.W.2d 41, 67–68 (Iowa 2013). Although Graham was limited to nonhomicide offenses, the defendant in the present case relied on the fact that Miller underscored that Graham’s rationale was not crime specific; see Miller v. Alabama, supra, 132 S. Ct. 2465; as support for the view that this second look opportunity extends to juve- nile homicide offenders. Two considerations persuade us that it would be inappropriate for us to resolve this question at this juncture. This court has recognized that ‘‘the fixing of prison terms for specific crimes involves a substantive peno- logical judgment that, as a general matter, is properly within the province of legislatures, not courts.’’ (Inter- nal quotation marks omitted.) State v. Higgins, 265 Conn. 35, 63, 826 A.2d 1126 (2003); accord State v. Heinemann, 282 Conn. 281, 311, 920 A.2d 278 (2007) (‘‘[w]e defer to the broad authority that legislatures possess in determining the types and limits of punish- ment for crimes’’); State v. Darden, 171 Conn. 677, 679– 80, 372 A.2d 99 (1976) (‘‘the constitution assigns to the legislature the power to enact laws defining crimes and fixing the degree and method of punishment and to the judiciary the power to try offenses under these laws and impose punishment within the limits and according to the methods therein provided’’). Staying our hand in deference to a coordinate branch of government is particularly appropriate in the present case. In the wake of Miller and Graham, the legislature directed the Con- necticut Sentencing Commission (commission) to make recommendations regarding reforms for the sentencing of juvenile offenders. Following the commission’s rec- ommendation, comprehensive bills were drafted relat- ing both to the consideration of youth, and its attendant characteristics, as a mitigating factor and to the provi- sion of a second look opportunity upon imposition of sentences in excess of ten years. See Substitute Senate Bill No. 1062, 2013 Sess.; Substitute House Bill No. 6581, 2013 Sess.; Substitute House Bill No. 5221, 2014 Sess. For reasons that are not apparent, in successive years, the bills were tabled in the Senate and were not acted upon before the expiration of the legislative sessions in which they were raised, thus requiring the legislature to take up the issue anew in the next session. In light of our decision in the present case, there is every reason to believe that the legislature will take definitive action regarding these issues with all deliberate speed. There- fore, for now, we will not provide the ‘‘means and mech- anisms for compliance’’ with the dictates of Graham. See Graham v. Florida, supra, 560 U.S. 75. In addition, concerns of ripeness counsel against reaching this issue. The defendant is entitled to a new sentencing proceeding. It is reasonably possible that the trial court will impose a less severe sentence than what is functionally life imprisonment without parole upon due consideration of the defendant’s age at the time of the offenses and the hallmark characteristics of youth as they bear on his conduct. Because the defen- dant’s claim rests on the factual predicate of a sentence that is the functional equivalent to life imprisonment without parole, it may be unnecessary for us to decide whether the defendant is entitled to a second look. See Chapman Lumber, Inc. v. Tager, 288 Conn. 69, 86–87, 952 A.2d 1 (2008) (‘‘in determining whether a case is ripe, [the] court must be satisfied that the case before [it] does not present a hypothetical injury or a claim contingent upon some event that has not and indeed may never transpire’’ [internal quotation marks omit- ted]). Indeed, at oral argument before this court, the defendant conceded that we need not reach this claim. The judgment of the Appellate Court is reversed and the case is remanded to that court with direction to reverse the judgment of the trial court only with respect to the defendant’s sentence and to remand the case to that court for a new sentencing proceeding consistent with this opinion. In this opinion ROGERS, C. J., and PALMER, EVE- LEIGH and ROBINSON, Js., concurred. 1 We use the term juvenile offenders to refer to persons who committed a crime when they were younger than eighteen years of age. 2 The Penal Code defines ‘‘life imprisonment’’ as a definite sentence of sixty years, unless a sentence of life imprisonment without the possibility of release is imposed, in which case the term means imprisonment for the remainder of the defendant’s natural life. See General Statutes § 53a-35b. The defendant was sentenced to sixty years on count one for murder; twenty years on count two for attempt to commit murder, consecutive to the first count; twenty years on count three for attempt to commit murder, consecu- tive to the first two counts; twenty years on count four for assault with a firearm, concurrent to the second count; twenty years on count five for assault in the first degree with a firearm, concurrent to the third count; and twenty years on count six for conspiracy to commit murder, concurrent to the previous counts. The defendant contends that the parole statute is ambiguous as to whether he is per se ineligible for parole because of his murder conviction; see General Statutes § 54-125a (b) (1) (E); or whether he is eligible after complet- ing the sentence for that offense and 85 percent of his sentences for the nonhomicide offenses. See General Statutes § 54-125a (b) (2) (B). Even under the interpretation more favorable to him, the defendant would not be eligible for release until he has served ninety-four years imprisonment. 3 See Haley v. Ohio, 332 U.S. 596, 599, 68 S. Ct. 302, 92 L. Ed. 224 (1948) (plurality) (instructing courts to take ‘‘special care’’ in considering confes- sion obtained from juvenile due to ‘‘great instability which the crisis of adolescence produces’’); Gallegos v. Colorado, 370 U.S. 49, 54, 82 S. Ct. 1209, 8 L. Ed. 2d 325 (1962) (noting that juvenile ‘‘cannot be compared with an adult in full possession of his senses and knowledgeable of the consequences of his admissions’’); Bellotti v. Baird, 443 U.S. 622, 635, 99 S. Ct. 3035, 61 L. Ed. 2d 797 (1979) (‘‘[T]he [c]ourt has held that the [s]tates validly may limit the freedom of children to choose for themselves in the making of important, affirmative choices with potentially serious consequences. These rulings have been grounded in the recognition that, during the formative years of childhood and adolescence, minors often lack the experience, perspective, and judgment to recognize and avoid choices that could be detrimental to them.’’); Eddings v. Oklahoma, 455 U.S. 104, 113–16, 102 S. Ct. 869, 71 L. Ed. 2d 1 (1982) (recognizing that youth is mitigating factor in determining whether to impose sentence of death on juvenile offender). 4 In Roper and Graham, the court first determined that there was a national consensus against the punishment at issue as applied to juvenile offenders before examining the proportionality of the punishment. See Roper v. Sim- mons, supra, 543 U.S. 567; Graham v. Florida, supra, 560 U.S. 62–67. 5 We note that, although some cases simply consider whether Miller is violated if the sentencer has discretion to impose a sentence of life without parole, others also consider whether the sentencer was required to consider the offender’s youth as a mitigating factor when exercising that discretion. Some courts have concluded that Miller only applies to sentences of manda- tory life without parole yet have made a point of concluding that the discre- tionary procedure conformed to Miller because the trial court considered the offender’s youth. Thus, we conclude that there is no clear consensus on this issue. Compare State v. Agboghidi, Docket No. 2 CA-CR 2013-0497- PR, 2014 WL 1572742 (Ariz. App. April 21, 2014) (treating as colorable claim that Miller applies to life sentence imposed under exercise of discretion), People v. Gutierrez, 58 Cal. 4th 1354, 1379, 324 P.3d 245, 171 Cal.
