Edwards v. Vannoy
The Court ruled that its landmark 2020 decision requiring unanimous jury verdicts does not apply retroactively, meaning people already imprisoned under non-unanimous verdicts cannot use it to seek new trials in federal court.
The ruling also permanently closed the last theoretical opening through which any new criminal procedure ruling could ever benefit defendants whose convictions are already final — a door the Court declared had never been meaningfully open in the first place.
How it got here: Edwards filed a federal habeas petition in the Middle District of Louisiana; the District Court rejected his claim; the Fifth Circuit denied a certificate of appealability; while his certiorari petition was pending, the Court decided Ramos, then granted cert to decide whether that ruling applied retroactively.
The Case in Depth
What happened
In 2007, Thedrick Edwards was convicted of armed robbery, rape, and kidnapping in Louisiana by split jury votes of 10-to-2 and 11-to-1. At the time, Louisiana allowed non-unanimous jury verdicts. While Edwards's case was pending before the Supreme Court, the Court decided Ramos v. Louisiana (2020), overruling prior precedent and holding that the Constitution requires unanimous jury verdicts in state criminal trials. Edwards argued that this newly announced right should apply to his already-final conviction.
The question before the Court
After the Supreme Court ruled that juries must be unanimous to convict someone of a serious crime, could people already in prison under non-unanimous jury verdicts use that ruling to demand new trials in federal court?
The Court's answer
No — the jury-unanimity rule announced in Ramos v. Louisiana does not apply retroactively on federal collateral review. Under the Court's long-established retroactivity framework (built around Teague v. Lane, 1989), new rules of criminal procedure take effect for cases still in trial courts or on direct appeal, but do not reach defendants whose convictions are already final. The Court found that Ramos plainly announced a new rule — prior precedent had allowed non-unanimous juries in state trials — and that the jury-unanimity rule does not fall within any exception.
The Court also went a significant step further: it formally declared that the one theoretical exception to this framework — the "watershed" exception for rules so fundamental that they must apply retroactively — is dead. The Court had described but never applied this exception in the 32 years since Teague. Acknowledging that reality, the majority declared the watershed exception "moribund" with "no vitality," meaning no future criminal procedure ruling can ever apply retroactively on federal habeas review.

Why it matters
People convicted by non-unanimous juries in Louisiana and Oregon who have already exhausted their direct appeals are locked out of using the Ramos ruling in federal court. More broadly, the decision makes clear that no future Supreme Court ruling on criminal procedure — no matter how fundamental — will ever be available to defendants whose convictions are already final in federal habeas proceedings.
What changes now
The Fifth Circuit's ruling is affirmed, and Edwards remains imprisoned under his non-unanimous jury convictions without benefit of the Ramos ruling. People convicted by non-unanimous juries in Louisiana and Oregon who have already exhausted their direct appeals cannot pursue federal habeas relief based on Ramos. States may still choose, on their own, to apply the jury-unanimity rule retroactively in their own state post-conviction proceedings. Going forward, no new criminal procedure ruling can ever apply retroactively in federal habeas proceedings.
What this does not decide
The ruling does not affect defendants whose cases were still on direct appeal when Ramos was decided — they are entitled to that ruling's benefit. It also does not prevent individual states from choosing, as a matter of their own state law, to apply the jury-unanimity rule retroactively in state post-conviction proceedings.
Concurrences and dissents
Concurrence — Justice Thomas
Justice Thomas joined the majority in full but wrote separately to argue that the federal habeas statute (AEDPA) independently resolves the case on its plain text. Because a Louisiana court reasonably denied Edwards's jury-unanimity claim under then-governing precedent (Apodaca), AEDPA's relitigation bar simply prevents any federal court from granting relief — full stop. Thomas would have begun and ended the analysis there, without reaching the Teague framework.
Concurrence — Justice Gorsuch
Justice Gorsuch wrote separately to provide a deep historical account of the writ of habeas corpus, arguing that the traditional common-law understanding never authorized federal courts to reopen final criminal judgments based on new procedural rules. He views the elimination of the watershed exception as a step back toward habeas's proper historical role, and finds the whole Teague 'watershed' enterprise — asking whether new rules are sufficiently 'fundamental' — to be an artificial exercise courts should never have undertaken.
Dissent — Justice Kagan
Justice Kagan argued that the jury-unanimity rule fits every criterion Teague specified for watershed status — it is fundamental, ancient, rooted in the Sixth Amendment's original meaning, essential to fair and accurate verdicts, and directly linked to preventing racial discrimination. She further argued that the majority improperly eliminated the watershed exception without any party asking it to do so, without adequate stare decisis justification, and in a single page of analysis — calling this an extraordinary and unprincipled departure from precedent. In her view, Thedrick Edwards should not die in prison based on a verdict the Court now says the Constitution never permitted.
How the Court got there
The legal reasoning, step by step
- Under the retroactivity framework the Court has applied since Teague v. Lane (1989), new rules of criminal procedure apply to cases still working through trials and direct appeals — but ordinarily do not apply retroactively on federal habeas corpus review, which is the process by which prisoners in final custody challenge their convictions in federal court. The Court's reasoning rests on the strong interest in the finality of criminal judgments: applying new rules retroactively could force retrials years after the crime, when evidence is stale and victims would have to testify again.
- The first step was determining whether Ramos announced a 'new' rule. A rule is new unless it was already dictated by prior precedent and obvious to all reasonable judges at the time a conviction became final. Because courts for decades had interpreted Apodaca v. Oregon (1972) to permit non-unanimous juries in state trials — and Ramos explicitly overruled Apodaca — the jury-unanimity requirement was clearly a new rule not dictated by earlier precedent.
- New procedural rules could still apply retroactively under one narrow exception: the 'watershed' exception for rules so fundamental to fair adjudication that they must reach all prisoners, even those with final convictions. In 32 years since Teague, the Court had described only one possible pre-Teague watershed rule — the right to an appointed lawyer from Gideon v. Wainwright (1963) — and had never once found any other rule to qualify.
- The Court rejected Edwards's three arguments for watershed status — the significance of jury unanimity, Ramos's grounding in the Sixth Amendment's original meaning, and Ramos's role in preventing racial discrimination in jury verdicts — by pointing to equally historic decisions that were also denied retroactive effect: Duncan v. Louisiana (establishing the jury-trial right itself), Crawford v. Washington (an originalist Sixth Amendment ruling on hearsay), and Batson v. Kentucky (barring race-based jury selection). The majority found no principled basis for treating Ramos differently from those precedents.
- Having exhausted the conventional analysis, the Court took the additional step of declaring the watershed exception formally dead — 'moribund,' retaining 'no vitality.' The Court reasoned that continuing to describe a theoretical exception that has never once applied in practice misleads defendants, lawyers, and courts, and that no one can have a reliance interest in an exception that exists only on paper. Because no post-Teague case ever actually found a rule to be watershed, the Court said it was overruling nothing — simply making explicit what the decades-long record had already made unmistakably clear.

The Court declared Teague's 'watershed' exception for retroactive application of new procedural rules permanently dead, with no future rule able to satisfy it.
Distinguishes Ramos v. Louisiana (590 U.S. ___)
The Court held that Ramos's jury-unanimity rule, though binding going forward, does not apply retroactively to reopen final convictions on federal habeas review.
Reaffirms Apodaca v. Oregon (406 U.S. 404)
The Court confirmed that Apodaca was already overruled by Ramos, and that its prior approval of non-unanimous juries was the benchmark showing Ramos announced a new rule.
