Pursuant to 28 U.S.C. §§ 2255(h) and 2244(b)(3)(A), Michael Morgan has filed an application seeking an order authorizing the district court to consider a second or successive motion to vacate, set aside, or correct his federal sentence, id. § 2255. Such authorization may be granted only if this Court certifies that the second or successive motion contains a claim involving:
(1) newly discovered evidence that, if proven and viewed in light of the evidence as a whole, would be sufficient to establish by clear and convincing evidence that no reasonable factfinder would have found the movant guilty of . the offense; or
(2) a new rule of constitutional law, made retroactive to cases on collateral review by the Supreme. Court, that was previously unavailable.
Id. § 2255(h). “The court of appeals may authorize the filing of a second or successive application only if it determines that the application makes a prima facie showing that the application satisfies the requirements of this subsection.” Id. § 2244(b)(3)(C).
Morgan indicates that he now wishes to raise one claim in a second or successive § 2255 motion. Specifically, he asserts that because: (i) he was a juvenile when he committed the acts leading to his convictions; (ii) one or more of those acts involved murder; and (hi) he received a mandatory sentence of life imprisonment without parole, under the then-mandatory Sentencing Guidelines, his constitutional rights were violated under the Eighth Amendment. Morgan asserts that his claim relies upon a new rule of constitutional law. He argues that Miller v. Alabama, 567 U.S. -, 132 S.Ct. 2455, 183 L.Ed.2d 407 (2012), established that imposing a life sentence without possibility of parole under the circumstances described above was unconstitutional, and because it was decided in June 2012, it announced a new, previously unavailable rule of constitutional law that is retroactive to cases on collateral review. Morgan contends that in In re Moss, 703 F.3d 1301 (11th Cir.2013), we held, in reference to a prisoner’s application for leave to file a successive section 2255 motion, that the applicant had made a prima facie showing that Graham v. Florida, 560 U.S. 48, 130 S.Ct. 2011, 176 L.Ed.2d 825 (2010), a Supreme Court case establishing that life imprisonment without parole for non-homicide juvenile offenders was unconstitutional, was retroactive. He asserts that we so held because we concluded that Graham addressed a specific type of sentence for an identifiable class of defendants, and Morgan argues that the same reasoning applies to Miller.
The decision of the Supreme Court in Miller established a new rule of constitutional law. A rule is new if it “was not dictated by precedent existing at the time the defendant’s conviction became final.” Teague v. Lane, 489 U.S. 288, 301, *1367109 S.Ct. 1060, 1070, 103 L.Ed.2d 384 (1989). Miller held for the first time that “the Eighth Amendment forbids a sentencing scheme that mandates life in prison without possibility of parole for juvenile offenders.” 132 S.Ct. at 2469. The Court reached this decision based on “the confluence of [ ] two lines of precedent .... ” Id. at 2464. The first line of precedents “adopted categorical bans on sentencing practices based on mismatches between the culpability of a class of offenders and the severity of a penalty.” Id. at 2463. Two of the decisions in this line of precedents held that minors were generally less culpable than other classes of offenders. See Graham, 130 S.Ct. at 2026; Roper v. Simmons, 543 U.S. 551, 569, 125 S.Ct. 1183, 1195, 161 L.Ed.2d 1 (2005). In those decisions, the Court had held that the Eighth Amendment prohibits capital punishment for minors, Roper, 543 U.S. at 578, 125 S.Ct. at 1200, and that the Eighth Amendment prohibits a sentence of life without the possibility of parole for a minor who had not committed a homicide offense, Graham, 130 S.Ct. at 2034.. But the Supreme Court had not extended this line of precedents to include minors who received a non-capital sentence when they committed homicide until Miller. The second line of precedents “prohibited mandatory imposition of capital punishment, requiring that sentencing authorities consider the characteristics of a defendant and the details of his offense before sentencing him to death.” Miller, 132 S.Ct. at 2463-64. But the Supreme Court had never extended this line of precedents beyond the imposition of the death penalty until Miller. See Lockett v. Ohio, 438 U.S. 586, 608, 98 S.Ct. 2954, 2967, 57 L.Ed.2d 973 (1978) (“To meet constitutional requirements, a death penalty statute must not preclude consideration of relevant mitigating factors.”); Woodson v. North Carolina, 428 U.S. 280, 305, 96 S.Ct. 2978, 2991, 49 L.Ed.2d 944 (1976) (“[T]he death sentences imposed upon the petitioners under North Carolina’s mandatory death sentence statute violated the Eighth and Fourteenth Amendments and therefore must be set aside.”). Although the “confluence of these two lines of precedent led[ ] to” the decision in Miller, 132 S.Ct. at 2464, Miller was not dictated by these precedents.
But the decision in Miller has not been made retroactive on collateral review. The requirement that a new rule be made retroactive on collateral review by the Supreme Court “is satisfied only if th[e] [Supreme] Court has held that the new rule is retroactively applicable to cases on collateral review.” Tyler v. Cain, 533 U.S. 656, 662, 121 S.Ct. 2478, 2482, 150 L.Ed.2d 632 (2001). And the Supreme Court has not held that Miller is retroactively applicable to cases on collateral review.
Morgan argues that we should conclude that Miller has been made retroactively applicable to decisions on collateral review because Miller created a new rule of constitutional law that prohibits a certain category of punishment for a class of defendants because of their status or offense, but we disagree. We have held that a prisoner may receive permission to file a second or successive motion to vacate, set aside, or correct a sentence when a decision of the Supreme Court creates a new rule of constitutional law that “prohibits] a certain category of punishment for a class of defendants,” Moss, 703 F.3d at 1303 (quoting Penry v. Lynaugh, 492 U.S. 302, 330, 109 S.Ct. 2934, 2953, 106 L.Ed.2d 256 (1989) abrogated on other grounds by Atkins v. Virginia, 536 U.S. 304, 122 S.Ct. 2242, 153 L.Ed.2d 335 (2002)), because multiple decisions of the Supreme Court “necessarily dictate retroactivity of the new rule,” Moss, 703 F.3d at 1303 (quoting Tyler, 533 U.S. at 666, 121 S.Ct. at 2484), but Miller did not prohibit the imposition *1368of a sentence of life imprisonment without the possibility of parole on minors. Instead, Miller held “that the Eighth Amendment forbids a sentencing scheme that mandates life in prison without possibility of parole for juvenile offenders.” 132 S.Ct. at 2469. Miller changed the procedure by which a sentencer may impose a sentence of life without parole on a minor by “requiring] [the sentencer] to take into account how children are different, and how those differences counsel against irrevocably sentencing them to a lifetime in prison.” Id. And the Court declined to consider “a categorical bar on life without parole for juveniles, or at least those 14 and younger.” Id.
Morgan argues that Miller is necessarily retroactive because any rule that expands the range of possible sentencing outcomes for a category of defendants by requiring that the sentencer have the option of imposing a lesser sentence is substantive, but we disagree. The Supreme Court has held that a new “rule[ ] prohibiting a certain category of punishment for a class of defendants because of their status or offense,” Penry, 492 U.S. at 330, 109 S.Ct. at 2953, is retroactive, but that rule applies only where a class cannot be subjected to a punishment “regardless of the procedures followed,” id. “In contrast, rules that regulate only the manner of determining the defendant’s culpability are procedural.” Schriro v. Summerlin, 542 U.S. 348, 353, 124 S.Ct. 2519, 2523, 159 L.Ed.2d 442 (2004). In Penry, the Court held that a rule that required that a sen-tencer be able “to give effect to [ ] mitigating evidence in determining whether a defendant should be sentenced to death,” Penry, 492 U.S. at 315, 109 S.Ct. at 2945, is retroactive, but the Court reached this conclusion because the rule was a procedural rule that was dictated by precedent, see id. at 319, 109 S.Ct. at 2947. A new rule is substantive when that rule places an entire class beyond the power of the government to impose a certain punishment regardless of the procedure followed, not when the rule expands the range of possible sentences.
Morgan’s application for leave to file a second or successive motion to vacate, set aside, or correct his sentence is DENIED.
