Do all 12 jurors have to agree for a guilty verdict in the USA?
Asked by: Taylor Greenholt | Last update: June 9, 2026Score: 4.9/5 (59 votes)
Yes, in the U.S. federal system and nearly all states, all 12 jurors must unanimously agree for a guilty verdict in serious criminal cases, a requirement solidified by the Supreme Court in Ramos v. Louisiana (2020), though Oregon was the last state to allow non-unanimous verdicts, which are now largely eliminated for serious crimes. If jurors can't agree, it's a hung jury, potentially leading to a mistrial.
Do all 12 jurors have to agree in a criminal case?

What if one jury member disagrees?
If one juror disagrees in a criminal case requiring unanimity, it leads to a hung jury (or deadlocked jury), resulting in a mistrial, meaning no verdict is reached, and the prosecution must decide whether to retry the case with a new jury, offer a plea deal, or drop charges. In civil cases, rules vary, but often a non-unanimous verdict is allowed, so one dissenter might not stop a decision, though a full deadlock still causes a mistrial.
