Summary

Background

A man charged with robbery in Florida asked a court not to enforce the State’s Rule 1.200, which requires defendants to give prosecutors advance written notice if they intend to claim an alibi and to provide names and addresses of alibi witnesses. He also asked for a 12-person jury instead of Florida’s six-person jury in noncapital cases. His request was denied, he gave the State the name of one alibi witness, was tried, convicted, and sentenced to life. The Florida appeals court rejected his constitutional claims and the U.S. Supreme Court agreed to decide the case.

Reasoning

The Court addressed two questions: whether requiring advance alibi notice forces a defendant to be a witness against himself, and whether the Sixth Amendment requires a 12-person jury. The Court held the alibi-notice rule does not violate the privilege against self-incrimination because it only accelerates disclosure of defenses the defendant would otherwise present at trial, and the rule is reciprocal and aimed at preventing last-minute fabricated alibis. On the jury issue the Court concluded that having exactly 12 jurors was a historical accident, not an indispensable constitutional requirement; a six-member jury can perform the jury’s protective function if other safeguards (like unanimity) remain.

Real world impact

The decision means states may continue or adopt reciprocal alibi-notice rules and may use six-member juries in noncapital cases. Prosecutors may depose or investigate defense alibi witnesses before trial. The Court did not decide here how severe sanctions may be if a defendant refuses to comply with notice rules.

Dissents or concurrances

Justice Marshall dissented as to the jury issue, arguing the Fourteenth Amendment guarantees a 12-person jury; Justice Black (joined by Justice Douglas) warned the alibi-disclosure rule risks undermining the Fifth Amendment privilege against self-incrimination.
