Edwards v. Vannoy
The Supreme Court ruled that its landmark 2020 decision requiring unanimous jury verdicts does not apply to prisoners whose cases were already final — blocking hundreds of people convicted under the old rules from seeking federal relief.
Going further, the Court eliminated the long-standing 'watershed' exception that had theoretically allowed historic new procedural rules to benefit prisoners in federal review, declaring that no new procedural rule can ever qualify for that exception.
How it got here: A federal district court rejected Edwards's habeas challenge under Apodaca; the Fifth Circuit denied a certificate of appealability; the Supreme Court agreed to hear the case while Ramos was pending.
The Case in Depth
What happened
Thedrick Edwards was convicted in Louisiana in 2007 of armed robbery, rape, and kidnapping on jury votes of 10-to-2 and 11-to-1 — because Louisiana law at the time allowed non-unanimous verdicts. His conviction became final in 2011. He then filed a federal challenge arguing he had a constitutional right to a unanimous jury. While his case was pending at the Supreme Court, the Court issued Ramos v. Louisiana (2020), ruling that the Constitution requires unanimous jury verdicts in state criminal trials. Edwards argued that ruling should apply to his already-final case too.
The question before the Court
Can a prisoner whose conviction became final before the Supreme Court ruled that jury verdicts must be unanimous use that ruling to demand a new trial in federal court?
The Court's answer
No — the Ramos jury-unanimity rule does not apply retroactively to convictions already final when Ramos was decided. Under the Court's longstanding retroactivity framework (the Teague doctrine), new procedural rules apply only to cases still on direct appeal, not to final convictions challenged afterward in federal habeas proceedings. Ramos announced a genuinely new rule because it expressly overturned Apodaca v. Oregon, which courts had long read to permit non-unanimous verdicts in state trials.
Going further, the Court formally eliminated the only theoretical path to retroactivity — the "watershed" exception, reserved for rules so fundamental they alter basic fairness. That exception had gone unsatisfied for all 32 years since it was introduced, and the Court said it was past time to stop pretending it remained available. No new procedural rule can qualify for retroactive application on federal habeas review.

Why it matters
Hundreds of prisoners in Louisiana and Oregon convicted by non-unanimous juries before 2020 remain unable to seek federal court relief based on the new unanimity rule. More broadly, the ruling closes off all future attempts by prisoners with final convictions to benefit from landmark changes in criminal procedure through federal habeas review, no matter how fundamental those changes may be.
What changes now
Thedrick Edwards — and all other prisoners convicted under non-unanimous jury verdicts whose direct appeals were already exhausted before Ramos — have no path to relief in federal court. States remain free to apply the jury-unanimity rule retroactively under their own state post-conviction procedures if they choose. The Court's elimination of the watershed exception means that no future landmark change in criminal procedure, however sweeping, can ever be used by prisoners with final convictions to seek federal habeas relief.
What this does not decide
The ruling does not affect defendants still on direct appeal, who automatically benefit from Ramos. It also does not bar states from voluntarily offering retroactive relief under their own state laws. The decision addresses only federal habeas review and says nothing about the underlying correctness of Ramos's unanimity rule.
Concurrences and dissents
Concurrence — Justice Thomas
Justice Thomas joined the majority fully but wrote separately to argue the case could have been resolved even more directly under AEDPA — the 1996 federal law governing habeas petitions. Because Louisiana's state court reasonably relied on Apodaca when rejecting Edwards's claim, AEDPA's plain text barred federal relief without any need to work through Teague. He also flagged historical doubts about whether Teague ever had valid statutory authority to grant retroactive habeas relief in the first place.
Concurrence — Justice Gorsuch
Justice Gorsuch wrote separately to provide an extensive historical account of habeas corpus, arguing that under centuries of English and American law, the writ never authorized courts to reopen a final criminal judgment issued by a court of competent jurisdiction. In his view, Teague's watershed exception should be abandoned not merely because it has never been satisfied, but because it rested on a fundamentally mistaken premise: that federal courts have authority to revisit final convictions whenever they disagree with their legal result.
Dissent — Justice Kagan
“So Thedrick Edwards, unlike Evangelisto Ramos, will serve the rest of his life in prison based on a 10-to-2 jury verdict.”Justice Kagan illustrates the human cost of denying retroactive effect to the jury-unanimity ruling.
Justice Kagan argued that jury unanimity is precisely the kind of watershed rule Teague described — the Court in Ramos called it 'vital,' 'essential,' 'indispensable,' and 'fundamental,' and invoked racial justice to justify overturning 50 years of precedent. She also accused the majority of improperly eliminating Teague's watershed exception without any party requesting that step, without going through the usual stare decisis analysis, and with barely a page of reasoning — calling it a casual discard of settled law.
How the Court got there
The legal reasoning, step by step
- The Court's retroactivity framework, established in Teague v. Lane (1989), holds that new rules of criminal procedure apply automatically to cases on direct appeal but ordinarily do not apply retroactively to overturn convictions already final — convictions where the defendant has exhausted all direct appeals. The rationale is that applying new rules to old, final convictions imposes heavy costs on finality and the justice system without proportionate benefit.
- The Court first asked whether Ramos announced a 'new' rule. A rule is new if it was not already required by prior precedent when the defendant's conviction became final. Because Ramos expressly overturned Apodaca v. Oregon — which many courts had read to permit non-unanimous jury verdicts in state trials — the jury-unanimity rule was plainly new. Reasonable jurists before Ramos interpreted Apodaca the other way.
- The only possible path to retroactivity was the so-called 'watershed' exception: a narrow carve-out for new procedural rules so integral to basic fairness that they override the usual finality rule. The Court had historically identified only one such watershed rule — the right to appointed counsel from Gideon v. Wainwright (1963). Every rule proposed as watershed since Teague had been rejected.
- Edwards argued Ramos deserved watershed status for three reasons: the fundamental significance of jury unanimity, Ramos's grounding in the Sixth Amendment's original meaning, and the rule's role in combating racial discrimination in verdicts. The Court rejected each argument by pointing to comparably significant cases — the jury-trial right itself (Duncan), an originalist Sixth Amendment confrontation ruling (Crawford), and a landmark anti-discrimination rule in jury selection (Batson) — none of which had been applied retroactively.
- Having concluded Ramos did not satisfy the watershed exception, the Court went further and declared the exception dead — 'moribund' in its word. Because no rule in 32 years had ever qualified, and the Court had repeatedly said it was 'unlikely' any rule ever would, continuing to describe the exception as available offered what the Court called 'false hope' to defendants and misled courts. Going forward, no new procedural rule can apply retroactively on federal habeas review.
