The defendant below-appellant Derrick Powell is appealing the Superior Court’s denial of his motion for postconviction relief.1 However, during the pendency of that appeal, Powell moved to vacate his death sentence based on the United States Supreme Court decision in Hurst v. Florida2 and this Court’s recent interpretation of that decision in Rauf v. State3 The only issue addressed in this decision is Powell’s motion to vacate his death sentence.
In Rauf, we held that, after Hurst, the capital sentencing procedures in Delaware’s death penalty statute are unconstitutional because the statute improperly permitted the imposition of a death sentence based upon a judicial determination of the necessary findings that the Sixth Amendment requires a jury to make.4 Specifically, Rauf held that those necessary findings must be made by a unanimous jury and beyond a reasonable doubt. Rauf also held that it was impossible to sever the constitutional infirmities in Delaware’s capital sentencing procedures.
The question presented by Powell’s motion is whether the holding in Rauf applies to a death sentence that was already final when Rauf was decided. We have concluded that this Court’s decision in Rauf applies retroactively to Powell’s case. Therefore, Powell’s death sentence must be vacated and he must be sentenced to “imprisonment for the remainder of his natural life without benefit of *71probation or parole or any other reduction.”5
Procedural Background
In February 2011, a Superior Court jury found Powell guilty of First Degree Murder for recklessly causing the death of Officer Chad Spicer while in flight from an attempted robbery, four counts of Possession of a Firearm During the Commission of a Felony, Resisting Arrest with Force or Violence, Attempted Robbery in the First Degree, and Reckless Endangering in the First Degree. Following a penalty hearing, the jury unanimously found beyond a reasonable doubt the existence of two statutory aggravators and, by a vote of seven to five, found by a preponderance of the evidence that the aggravating factors outweighed the mitigating factors and recommended that a sentence of death be imposed. The trial judge found the existence of several non-statutory aggravating factors and by a preponderance of the evidence that all of the aggravating factors outweighed the mitigating factors and imposed a sentence of death.6 On August 9, 2012, this Court affirmed Powell’s convictions and death sentence.7
After this Court affirmed his convictions and death sentence, Powell filed a pro se motion for postconviction relief in the Superior Court. The court appointed counsel, who filed an amended motion for postcon-viction relief on October 1, 2013. Over the next two years, the record was expanded to include attorney affidavits and an evi-dentiary hearing. On May 24, 2016, the Superior Court denied Powell postconviction relief.8 Powell’s appeal from the denial of his motion for postconviction relief is currently pending before this Court.
Hurst and Rauf
On January 12, 2016, the United States Supreme Court issued its decision in Hurst, holding that Florida’s death penalty statute was unconstitutional.9 The Superior Court certified five questions to this Court in accordance with Delaware Supreme Court Rule 41.10 This Court accepted the five questions certified by the Superior Court, but revised the questions to remove any reference to the Delaware Constitution. On August 2, 2016, after briefing and oral argument, this Court, sitting en banc, answered the revised certified questions. In Rauf, we concluded that the Delaware death penalty statute, 11 Del. C. § 4209, is unconstitutional under federal law.11
In Rauf, this Court did not address whether Hurst or Rauf should be applied retroactively to capital cases currently in various stages of collateral review. Consequently, Powell, whose case is before this Court on appellate review from the denial of postconviction relief, moved to vacate his death sentence. He argues that Hurst and Rauf should be retroactively applied to his case.
Retroactivity Rules
The normal federal framework for determining whether a new rule applies to cases on collateral review is based upon the United States Supreme Court’s plurali*72ty opinion in Teague v. Lane.12, Teague held that, as a general matter, “new constitutional rules of criminal procedure will not be applicable to those cases which have become final before the new rules are announced.”13 Nevertheless, Teague and its progeny recognize two exceptions to the general bar on retroactivity. First, “[n]ew substantive rules generally apply retroactively.”14 Second, new “watershed rules of criminal procedure,” which are procedural rules “implicating the fundamental fairness and accuracy of the criminal proceeding,” will also have retroactive effect.15
In Danforth v. Minnesota,16 the United States Supreme Court explained that “Teague’s general rule of nonretroactivity was an exercise of [its] power to interpret the federal habeas statute” and “cannot be read as imposing a binding obligation on state courts.”17 Nevertheless, more than twenty-five years ago this Court recognized the Teague general rule of non-retro-activity and its two exceptions as persuasive authority for deciding whether new state and federal precedents are to be applied retroactively in Delaware postcon-viction proceedings.18 In doing so, we noted that the federal Teague “new rule” doctrine was evolving and that State courts may grant postconviction “relief to a broader class of individuals than is required by Teague.”19 Therefore, we declined to adopt a formal static test for determining the meaning of a “new rule” for the purposes of deciding a Delaware postconviction proceeding.
In Danforth, the Supreme Court stated:
It is thus abundantly clear that the Teague rule of nonretroactivity was fashioned to achieve the goals of federal habeas while minimizing federal intrusion into state criminal proceedings. It was intended to limit the authority of federal courts to overturn state convictions—not to limit a state court’s authority to grant relief for violations of new rules of constitutional law when reviewing its own State’s convictions.20
Accordingly, the retroactivity issue that is presented by Powell’s motion is a matter of Delaware law. In analyzing that issue we look to Teague and its progeny for guidance.21 However, as the United States *73Supreme Court held in Danforth, the post-conviction retroactivity remedy that a state court provides for “violations of the Federal Constitution is primarily a question of state law.”22
Rauf Applies Ring, Hurst, and Apprendi
We have concluded that the decision in Rauf falls within our interpretation of Teague’s second exception to non-retroac-tivity. The State’s reliance on Schriro v. Summerlin’s23 refusal to find Ring v. Arizona24 retroactive is misplaced. In Apprendi v. New Jersey,25 the United States Supreme Court held that “any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to the jury, and proved beyond a reasonable doubt”26 In Ring, the United States Supreme Court extended Apprendi to find that “[cjapital defendants ... are entitled to a jury [rather than a judicial] determination of any fact on which the legislature conditions an increase in their maximum punishment.”27
Ring’s claim was “tightly delineated[.] He contended] only that the Sixth Amendment required jury findings on the aggravated circumstances asserted against him.”28 Ring’s claim did not implicate the Due Process Clause because “Arizona law already required aggravating factors to be proved beyond a reasonable doubt and that aspect of Apprendi was not at issue. 29 Indeed, the Summerlin Court took special notice in its first footnote that Ring did not address the burden of proof30 Accordingly, Summerlin only addressed the misallocation of fact-finding responsibility (judge versus jury) and not, like Rauf the applicable burden of proof.31
The Supreme Court began its opinion in Hurst by holding that “[t]he Sixth Amendment requires a jury, not a judge, to find each fact necessary to impose a sentence of death. A jury’s mere recommendation is not enough.”32 The Supreme Court also held, as it had in Apprendi, that the Sixth Amendment, in conjunction with the Due Process Clause, “requires that each element of a crime be proved to a jury beyond a reasonable doubt.”33
Ring only implicated the Sixth Amendment right to a jury. The same was true in Hurst because Florida also already re*74quired proof beyond a reasonable doubt.34 When Hurst was remanded, the Florida Supreme Court summarized its law as follows:
Thus, before a sentence of death may be considered by the trial court in Florida, the jury must find the existence of the aggravating factors proven beyond a reasonable doubt, that the aggravating factors are sufficient to impose death, and that the aggravating factors outweigh the mitigating circumstances. These same requirements existed in Florida law when Hurst was sentenced in 2012—although they were consigned to the trial judge to make.35
Thus, unlike Rauf, neither Ring nor Hurst involved a Due Process Clause violation caused by the unconstitutional use of a lower burden of proof. This significant distinction in Ring and Hurst is fatal to the State’s reliance upon Summerlin and is dispositive of why the Rauf holding fits within Teague’s second exception to nonre-troactivity.
The second exception to non-retro-activity in Teague held that a new procedural rule applies retroactively if it is a new “watershed rule of criminal procedure” (1) “implicit in the concept of ordered liberty,” implicating “fundamental fairness,” and (2) central to an accurate determination of innocence or guilt,” such that its absence “creates an impermissibly large risk that the innocent will be convicted.”36 “In the context of a death sentence, where the matter is not one of ‘innocence or guilt,’ the second criterion asks whether the new procedure is ‘central to an accurate determination’ that death is a legally appropriate punishment.”37
Rauf Is Watershed Ruling
Based upon Hurst, Rauf overruled our prior decision Brice v. State38 and announced a new watershed procedural rule for capital proceedings that contributed to the reliability of the fact-finding process.39 Thus, Rauf falls squarely within the second exception set forth in Teague requiring retroactive application of “new rules” of criminal procedure “without which the likelihood of an accurate [sentence] is seriously diminished.”40 We also note that Teague’s holding on the retroactivity of new rules of criminal procedure was based upon the opinion of Justice Harlan, who acknowledged that “some rules may have both procedural and substantive ramifications.”41
The burden of proof is one of those rules that has both procedural and substantive ramifications.42 Prior to our holding in *75Rauf the burden of proof was governed by the lesser standard of a preponderance of the evidence set forth in Delaware’s death penalty statute.43 Rauf recognized that, after Apprendi, substantive Due Process required the higher “beyond a reasonable doubt” burden of proof. As we observed in Rauf, “[t]here is no circumstance in which it is more critical that a jury act with the historically required confidence than when it is determining whether a defendant should live or die.”44
Rauf Applies Retroactively
The question of whether the new higher burden of proof standard recognized in Rauf is retroactive was decided by the United States Supreme Court more than forty years ago.45 In Ivan V. v. City of New York,46 the Supreme Court held that the new rule announced in In re Win-ship,47 changing the burden of proof for fact-finding from the “preponderance of evidence” standard to a “beyond a reasonable doubt” standard, must be applied retroactively because that change implicated fact-finding reliability under the Due Process Clause. In Winship, the Court had held that juveniles must be afforded the benefit of the reasonable doubt standard when charged with an act that would be a crime if committed by an adult.
In Ivan V., the Supreme Court concluded that the new rule articulated in Winship must be applied retroactively because the reasonable doubt standard is the sort of requirement without which the truth-finding function of a criminal trial is substantially impaired:
Winship expressly held that the reasonable-doubt standard “is a prime instrument for reducing the risk of convictions resting on factual error. The standard provides concrete substance for the presumption of innocence—that bedrock “axiomatic and elementary” principle whose “enforcement lies at the foundation of the administration of criminal law.”
* * * *
[T]he major purpose of the constitutional standard of proof beyond a reasonable doubt announced in Winship was to overcome an aspect of a criminal trial that substantially impairs the truth-finding function, and Winship is thus to be given complete retroactive effect.48
In Winship, the Supreme Court explained that a conviction based upon the eivil preponderance standard would amount to “a lack of fundamental fairness.”49 Later, Teague incorporated the “fundamental fairness” language from Ivan V. into its watershed procedural rule exception to non-retroactivity.50 In Hankerson v. North Carolina,51 another pre-Teague decision, the United States Supreme Court observed.“we have never deviated from the rule stated in Ivan V. that ‘[wjhere the major purpose of new consti*76tutional doctrine is to overcome an aspect of the criminal trial that substantially impairs its truth-finding function and so raises serious questions about the accuracy of guilty verdicts in past trials, the new rule (is) given complete retroactive effect.’”52 The change in the burden of proof in Winship that was ruled retroactive in Ivan V. is no different from the change in the burden of proof that occurred in Rauf.
Conclusion
The decision in Rauf constitutes a new watershed procedural rule of criminal procedure that must be applied retroactively in Delaware, pursuant to our interpretation of Teague’s second exception to non-retroactivity. Accordingly, we hold that Rauf mast be applied retroactively to Powell’s case. Therefore, Powell’s death sentence must be vacated and he must be sentenced to “imprisonment for the remainder of his natural life without benefit of probation or parole or any other reduction.”53
This decision is consistent with two prior opinions when this Court held that the extant death penalty statutes were unconstitutional and vacated all death sentences. In 1973, following the United States Supreme Court decision in Furman,54 this Court held that the existing Delaware death penalty statute was unconstitutional.55 The three remaining prisoners on Delaware’s death row at the time had their death sentences vacated and were resen-tenced to life imprisonment. Four years later, after the United States Supreme Court decision in Woodson v. North Carolina,56 this Court held Delaware’s mandatory death-sentencing statute was unconstitutional.57 State v. Spence consolidated the cases of all nine prisoners that had been sentenced to death under the mandatory scheme.58 We held that the death sentences of all nine should be vacated and each should be sentenced to life imprisonment without parole.59
