Supreme Court to Decide if Criminal Trials Require 12 Jurors, in Florida Case

The U.S. Supreme Court has agreed to take up a Florida case that could fundamentally alter the constitutional floor for criminal jury trials — deciding, for the first time in decades, whether the Sixth Amendment requires all 12 jurors to agree before a defendant can be convicted.

The case reaches the nation's highest court after years of legal friction over Florida's jury rules, which have at times permitted non-unanimous verdicts in certain criminal proceedings. The justices accepted the case without comment, a standard procedural step that tells courts the question is ripe for a definitive answer.

For residents in Martin, St. Lucie, and Indian River counties, the stakes are concrete. Every felony tried in the Nineteenth Judicial Circuit — which covers all three Treasure Coast counties — flows through a jury system that would be directly subject to any new constitutional standard the Court sets. A ruling mandating unanimous 12-person juries in all serious criminal cases could affect pending prosecutions, sentencing timelines, and potentially open post-conviction challenges for defendants whose verdicts fell short of that bar.

The legal question has a complicated recent history. In 2020, the Supreme Court ruled in Ramos v. Louisiana that the Sixth Amendment requires unanimous jury verdicts in state criminal trials — overturning convictions in Louisiana and Oregon, two states that had long allowed split verdicts. The new Florida case pushes further, focusing on whether 12 jurors — not just unanimity among however many are seated — is itself a constitutional requirement, according to public records related to the Court's docket.

Some Florida courts have used juries of fewer than 12 in certain non-capital felony cases, a practice that has gone largely unchallenged at the federal level, legal scholars note.

A decision is expected before the Court's term ends in June 2026. Any ruling would carry immediate weight for state prosecutors and defense attorneys across Florida's 20 judicial circuits.
