What if only one juror disagrees?
Asked by: Miss Brionna Kilback IV | Last update: April 23, 2026Score: 4.6/5 (58 votes)
If one juror disagrees in a criminal trial requiring unanimity, it leads to a hung jury, a deadlock where no verdict can be reached, resulting in a mistrial; the judge dismisses the jury, and the prosecutor decides whether to retry the case, drop charges, or offer a plea deal. In civil cases, rules vary, but often fewer than all jurors need to agree (e.g., 9 out of 12 in some jurisdictions), and a single dissenter might not block a verdict, as seen in California civil trials.
Do all 12 jurors have to agree?
Yes, in all federal criminal cases and most state criminal cases in the U.S., all 12 jurors must agree (reach a unanimous verdict) for a conviction or acquittal, a requirement solidified for serious crimes by the U.S. Supreme Court case Ramos v. Louisiana in 2020. While some states previously allowed non-unanimous decisions (like Oregon and Louisiana), the Supreme Court ruled this unconstitutional for serious criminal cases, leading to mistrials (hung juries) if jurors can't agree. In civil cases, rules vary, but often a supermajority (like 10 out of 12 or three-fourths) is sufficient.
Can a single juror nullify?
As such, individual jurors have the power to profess a moral quandary and nullify a verdict, keeping a guilty defendant from going to prison despite overwhelming evidence refuting their innocence. This power is far too extreme to be granted to a single individual.
How many jurors have to say not guilty to be not guilty?
The law requires twelve (12) jurors to be seated in a criminal case, only eight (8) jurors are required in a civil case. In a criminal trial, the jury must find a litigant “guilty” or “not guilty” by unanimous vote. In civil cases the law requires a vote of at least three-fourths of the jury to reach a verdict.
Has a judge ever overrule a jury verdict?
Yes, judges can and do overturn jury verdicts, though it's rare, usually when there's insufficient evidence for the verdict, the verdict is against the weight of the evidence (showing passion or prejudice), or due to significant legal errors during the trial, allowing for motions like Judgment Notwithstanding the Verdict (JNOV) or ordering a new trial, especially in criminal cases where a conviction might be overturned but not an acquittal.
What happens if Arias jurors can't agree?
What if one juror disagrees?
If one juror disagrees in a criminal trial, it often leads to a hung jury (deadlocked jury) and a mistrial, meaning no verdict is reached and the prosecutor might retry the case or drop charges, but in some states (like Oregon historically), a non-unanimous vote could still convict, although federal cases and most states require unanimous verdicts for criminal convictions. In civil cases, requirements vary by state, but often fewer than 12 jurors agree, and some states allow non-unanimous verdicts, but a complete deadlock still results in a mistrial.
How often is the jury wrong?
The identification error is similarly one-sided, always. From the observed agreement rates, the probability of a correct verdict by the jury is estimated at 87% for the NCSC cases and 89% for the Kalven-Zeisel cases. Those accuracy rates correspond to error rates of 1 in 8 and 1 in 9, respectively.
Is not guilty better than dismissed?
While both are great outcomes, an acquittal ("not guilty" verdict) is generally considered stronger because it's a final declaration of innocence after a trial, while a dismissal stops the case without ruling on guilt and might allow refiling unless it's "with prejudice" (permanently closed). An acquittal means the prosecution failed to prove guilt beyond a reasonable doubt; a dismissal means the case ended for other reasons, like insufficient evidence or procedural issues, but doesn't formally declare innocence, though it avoids conviction.
Can one juror cause a mistrial?
Yes. It happened to me a few times in my 30 year career as a prosecutor that one or more jurors would deadlock the 12 member jury panel. The judge would be forced to declare a mistrial and we'd select a new trial date to do the case all over again.
Who is more powerful, a judge or a jury?
Neither the jury nor the judge is universally "more powerful"; they have distinct roles, but in most criminal trials, the jury holds the ultimate power to decide guilt or innocence (the verdict), while the judge controls the legal process, determines what evidence is admitted, and imposes the sentence. The jury acts as the finder of fact and applies the law as instructed, but the judge ensures fairness, manages evidence (ruling on objections), and interprets the law, making them powerful in shaping the trial's direction and outcome.
What is the best excuse to get out of jury duty?
The best ways to get out of jury duty involve claiming legitimate exemptions (like being over 70, a primary caregiver, or a student) or demonstrating undue hardship (serious medical issues, financial strain, or prior jury service), usually by contacting the court with supporting documentation like a doctor's note or employer letter, or by being honest about biases during voir dire (jury selection) so attorneys strike you; however, making extreme false statements can backfire, and the court always makes the final decision.
What are two things jurors should never do?
Two critical things jurors should never do are research the case or visit the scene independently, and discuss the case with anyone outside the jury, including family, friends, or on social media, to ensure the verdict relies solely on evidence presented in court. Violating these rules, like becoming an "amateur detective" or getting outside opinions, can lead to a mistrial because it introduces biased information, according to the California Courts website and the Western District of Pennsylvania court guide.
Can a juror be removed during deliberation?
Once deliberations have begun, discharge of a juror is warranted only in the most extreme situations where it can be shown that the removal of the juror (1) is necessary for the integrity of the process, (2) does not prejudice the deliberations of the rest of the panel, and (3) does not impair the party's right to a ...

What happens if a jury member falls asleep?
If you fall asleep during jury duty, a court officer or the judge will likely wake you up, and you could be dismissed from the jury for inattentiveness, potentially leading to a mistrial if you miss crucial evidence, though minor dozing might just result in a warning, while repeated sleeping is grounds for removal and requires a judge to decide if the trial fairness was compromised.
Why should you never plead guilty?
You should never plead guilty without understanding the severe, life-altering consequences, as it creates a permanent criminal record, waives your rights (like a trial), and can lead to unforeseen issues with jobs, housing, immigration, or education, even if you later feel you were partially at fault or could have gotten a better deal, with a lawyer crucial for navigating complex plea bargains and potential defenses.
What is the most popular reason that cases get dismissed?

Can a judge throw out a jury decision?
Yes, a judge can overrule or set aside a jury's verdict, but it's rare and only happens under specific legal circumstances, like when there's insufficient evidence to support the verdict, the jury misapplied the law, or damages are grossly excessive, using mechanisms like a Judgment Notwithstanding the Verdict (JNOV) or Judgment of Acquittal. Judges must respect jury decisions, so they generally only intervene when a verdict is clearly unreasonable or against the law, not simply because they disagree with the outcome.
