Williams v. Florida

an influential 1970 U.S. Supreme Court ruling that juries of fewer than 12 people are constitutionally permissible. The court indicated that although the size of a jury is an important factor in its effectiveness, juries having as few as six members could function as effectively as juries of 12 members. This ruling was also notable for upholding the notion that in a criminal trial, the Fifth Amendment does not allow the defendant to refuse to provide to the prosecution details about his or her alibi witnesses.
