The Supreme Court agreed on Monday to hear a case that could reshape criminal trial procedure across the country, taking up the question of whether the Constitution requires twelve jurors in serious criminal cases. The dispute arrives from Florida, where a man convicted of armed robbery by a six-person jury argues the practice violates his Sixth Amendment right to a trial by jury.
The case, Kharon Davis v. Florida, puts a half-century-old precedent squarely in the crosshairs. In 1970, the Court ruled in Williams v. Florida that six-member juries satisfy the Constitution. Now, with fresh briefing and a new petitioner, the justices will decide whether that holding should survive.
Kharon Davis was convicted of armed robbery in Florida state court by a jury of six, the Associated Press reported. He received a sentence of life in prison as a habitual offender. His legal team argues that the Sixth Amendment, as understood at the founding and through centuries of common law tradition, guarantees a twelve-person jury for serious criminal offenses. Florida is one of just two states that still use six-person juries in non-capital felony cases. Louisiana is the other.
Davis's attorneys contend that Williams v. Florida was wrongly decided and broke with the original public meaning of the Sixth Amendment's jury trial guarantee. The petition frames the question in originalist terms, arguing that at the time of ratification, a "jury" meant twelve people, full stop.
The 1970 Williams decision held that the number twelve was a "historical accident" with no constitutional significance. Writing for the majority, Justice Byron White concluded that a jury's essential feature was its role as a cross-section of the community interposed between the accused and the state, not its headcount.
That reasoning drew criticism almost immediately. Justice Thurgood Marshall dissented in a related case, and legal scholars on both sides of the ideological spectrum have questioned the historical analysis underlying Williams for decades. The Court itself pulled back from extending the logic further when it struck down five-person criminal juries in Ballew v. Georgia in 1978, finding that panels smaller than six raised serious concerns about the quality of deliberation and the accuracy of verdicts.
Critics of Williams argue the decision rested on a functional analysis that ignored the text and history of the Sixth Amendment. Supporters of the status quo counter that decades of state reliance on six-person juries in thousands of cases creates a powerful interest in stability.
The cert petition leans heavily on originalist methodology, the same interpretive approach the current Court has embraced in landmark cases involving the Second Amendment, the Confrontation Clause, and other constitutional provisions. Davis's lawyers argue that every major treatise and legal dictionary from the founding era defined "jury" as a body of twelve. English common law stretching back to the fourteenth century treated the twelve-person requirement as a fixed feature of the right to jury trial, not a detail Parliament or the Crown could adjust downward.
The argument fits neatly into a broader pattern at the Roberts Court. In Ramos v. Louisiana in 2020, the justices overturned Apodaca v. Oregon and held that the Sixth Amendment requires unanimous jury verdicts in state criminal trials. Justice Neil Gorsuch, writing for the majority in Ramos, emphasized original meaning and the historical pedigree of the unanimity requirement. Davis's petition explicitly invokes Ramos as a template, arguing that the same originalist reasoning compels the same result on jury size.
Justice Gorsuch's Ramos opinion even noted, without deciding, that the Court's earlier jury-size cases rested on shaky ground. That footnote signaled to litigants and lower courts that the question was ripe for reconsideration.
Florida defended its practice in opposing certiorari, arguing that Williams has been settled law for more than fifty years and that overruling it would disrupt the state's criminal justice system. Florida processes a high volume of felony cases using six-person juries, and state officials warned that requiring twelve-person panels would strain courthouse resources, lengthen trial schedules, and expand the burden on citizens called for jury service.
The practical consequences extend beyond Florida and Louisiana. While most states already use twelve-person juries for felonies, a ruling that the Sixth Amendment mandates that number could also affect how states structure juries for certain misdemeanor trials. Federal courts already require twelve-person juries in criminal cases under the Federal Rules of Criminal Procedure, so the decision would not change federal practice.
The retroactivity question looms large as well. If the Court overrules Williams, defendants previously convicted by six-person juries could seek to challenge their convictions. The scope of any retroactive application would likely generate its own wave of litigation, much as Ramos did after 2020.
The Sixth Amendment states that "in all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury." The text does not specify a number. Proponents of the twelve-person requirement argue that the word "jury" carried a fixed meaning in 1791 that included the number twelve as an essential element, just as "trial" carried the requirement of live testimony and confrontation.
Historical sources marshaled in the briefing include Blackstone's Commentaries, which described the twelve-person jury as fundamental to English liberty, and ratification-era state constitutions that either specified twelve or used "jury" with the understood meaning of twelve. Davis's lawyers argue that no evidence from the founding era supports the idea that a legislature could reduce the number below twelve and still call the proceeding a jury trial.
The state's counterargument rests partly on the distinction between the federal Sixth Amendment and the Fourteenth Amendment's incorporation of that right against the states. Florida has suggested that even if twelve was the original federal requirement, incorporation through the Due Process Clause permits some flexibility. The Court rejected a similar argument about unanimity in Ramos, holding that incorporated rights apply with equal force against the states.
The current Court has shown a willingness to overturn precedents it views as historically unsound. Beyond Ramos, the justices overruled Roe v. Wade in Dobbs, reversed decades of administrative-law doctrine in Loper Bright, and reconsidered long-settled Commerce Clause assumptions. Each of those decisions emphasized fidelity to text and original meaning over reliance on stare decisis alone.
That track record makes Williams look vulnerable. The 1970 opinion relied on a functional, living-constitution style of analysis that sits uncomfortably alongside the originalist framework the current majority has applied elsewhere. If the Court treats jury size the way it treated jury unanimity in Ramos, the outcome is difficult to predict but the direction of the analysis favors Davis.
Still, stare decisis carries weight even for originalist justices, and the reliance interests in this case are substantial. Thousands of convictions in Florida rest on six-person jury verdicts. The Court may look for ways to limit retroactive disruption even if it rules in Davis's favor on the merits.
The Court did not immediately schedule oral argument. The case will likely be argued during the October 2025 term, with a decision expected by June 2026. Both sides will file merits briefs in the coming months, and the case is expected to draw significant amicus participation from state attorneys general, criminal defense organizations, legal historians, and constitutional scholars.
Davis remains incarcerated in Florida while his case proceeds. His life sentence for armed robbery stands unless the Court rules in his favor and the conviction is subsequently vacated or a new trial ordered.
The justices framed the question presented narrowly: whether the Sixth Amendment right to a jury trial, as incorporated against the states, requires a twelve-person jury in criminal proceedings. That framing leaves room for the Court to address jury size without necessarily reaching broader questions about misdemeanor juries or civil cases.
Investigators of constitutional history will watch closely to see whether the Court applies the same two-step originalist analysis it used in Ramos: first, what did the right mean at the founding, and second, does incorporation require the states to honor that meaning fully. If the answer to both questions is yes, Williams falls.
The case also tests whether the Court's originalist majority will apply its methodology consistently even when the practical consequences are costly and the precedent being challenged has deep institutional roots. Consistency is the price of credibility for any interpretive framework.
When the government puts a citizen's liberty on the line, the Constitution sets the rules for how that happens. The question before the Court is whether twelve jurors is one of those rules, or merely a tradition states can trim when the docket gets crowded.
