Ramos v. Louisiana held that state felony convictions for serious offenses require unanimous juries. The decision overruled Apodaca v. Oregon and invalidated Louisiana's and Oregon's non-unanimous jury systems. The Court emphasized both constitutional text and history, including the racist roots of Louisiana's rule.
Louisiana adopted non-unanimous felony juries after Reconstruction as part of a broader effort to weaken Black civic power. Oregon's rule also had discriminatory roots. Ramos challenged a system that allowed the state to convict even when two jurors voted not guilty.
Does the Sixth Amendment require unanimous jury verdicts for serious criminal offenses in state court?
The Sixth Amendment requires a unanimous jury verdict to convict a defendant of a serious offense, and that requirement applies to the states through the Fourteenth Amendment.
How the justices lined up in this decision.
The ruling protected criminal defendants from being convicted when some jurors have reasonable doubt. It had special significance in Louisiana, where the non-unanimous jury rule grew from a Jim Crow convention meant to weaken Black jurors' power. The decision forced Louisiana and Oregon to use unanimous juries going forward and opened litigation over older convictions.
Justice Gorsuch announced the judgment. Justices Ginsburg, Breyer, Sotomayor, and Kavanaugh joined key parts; Justice Thomas concurred in the judgment. Justice Alito dissented, joined by Chief Justice Roberts and in large part by Justice Kagan.
