Jury nullification
when a jury finds a defendant not guilty because they disagree with a law or its punishment
Jury nullification, also known as jury equity or as a perverse verdict, is a decision by the jury in a criminal trial resulting in a verdict of not guilty even though they believe a defendant has broken the law. The jury's reasons may include the belief that the law itself is unjust, that the prosecutor has misapplied the law in the defendant's case, that the punishment for breaking the law is too harsh, or general frustrations with the criminal justice system. It has been commonly used to oppose what jurors perceive as unjust laws, such as Amercian laws that once penalized runaway slaves under the Fugitive Slave Act, prohibited alcohol during Prohibition, or criminalized draft evasion during the Vietnam War. Some juries have also refused to convict due to their own prejudices in favor of the defendant. Such verdicts are possible because a jury has an absolute right to return any verdict it chooses.
Nullification is not an official part of criminal procedure, but is the logical consequence of two rules governing the systems in which it exists:
Jurors cannot be punished for the verdict they make.
In many jurisdictions, a defendant who is acquitted cannot be tried a second time for the same offense. (At least by the exact same jurisdiction. In the United States, defendants can oftentimes be prosecuted by both the State, and Federal government for what is essentially the same crime under the separate sovereigns doctrine. See Gamble v.
This brief starts where responsible research should: with the source description of “Jury nullification” as when a jury finds a defendant not guilty because they disagree with a law or its punishment. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as when a jury finds a defendant not guilty because they disagree with a law or its punishment. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q2619009. None of the 0 selected statements returned an explicit reference.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
