Jury nullification in the United States

In the United States, jury nullification occurs when a jury in a criminal case reaches a verdict contrary to the weight of evidence, sometimes because of a disagreement with the relevant law. It has its origins in colonial America under British law. The American jury draws its power of nullification from its right to render a general verdict in criminal trials, the inability of criminal courts to direct a verdict no matter how strong the evidence, the Fifth Amendment's Double Jeopardy Clause, which prohibits the appeal of an acquittal, and the fact that jurors cannot be punished for the verdict they return. rdf:langString
