Batson v. Kentucky
The defendant appealed his conviction to the Kentucky Supreme Court, which upheld the conviction. That court cited Swain v. Alabama, and held that a defendant claiming lack of a fair cross section must demonstrate systematic exclusion of a group of jurors from the panel of prospective jurors. That is, the defendant had to show that not just in his case, but as a process, juries in his community did not represent a cross section of that community. Batson continued his appeal to the U.S. Supreme Court, which granted certiorari to decide whether petitioner was tried "in violation of constitutional provisions guaranteeing the defendant an impartial jury and a jury composed of persons representing a fair cross section of the community."
