Edwards v. Vannoy

Background

A man convicted in Louisiana in 2007 was found guilty by non‑unanimous juries (11–1 and 10–2 votes). After his conviction became final, he sought federal post‑conviction review (a habeas petition) arguing his trial violated a unanimous‑jury right. Lower courts relied on an older decision allowing non‑unanimous verdicts. While his petition was pending, this Court in Ramos said state juries must be unanimous, overruling the older case.

Reasoning

The Court applied its retroactivity framework and said new criminal procedure rules normally do not undo final convictions on federal collateral review. Ramos announced a new rule because it overruled the old precedent, but the Court concluded that rule is not a rare “watershed” procedural rule that must apply retroactively. The majority compared Ramos to other major decisions that were also denied retroactive effect, stressed States’ reliance and retrial costs, and declared the theoretical watershed exception moribund.

Real world impact

Because Ramos does not apply retroactively on federal habeas review, people with final convictions from non‑unanimous juries cannot use Ramos to get federal relief. The Ramos rule still governs cases on direct appeal and trials going forward. The Court noted retrials years later would burden victims, courts, and evidence, and added that States remain free to apply the unanimity rule in their own post‑conviction systems.

Dissents or concurrances

Two Justices stressed statutory and procedural reasons supporting the majority outcome. A dissent argued Ramos is a watershed rule tied to history and racial harms and should apply retroactively.
