Linkletter v. Walker
Headline: Fourth Amendment evidence rule limited: Court refuses to apply Mapp to convictions final before the decision, leaving many pre-Mapp state prisoners without relief while applying Mapp to pending appeals.
Holding: The Court held that Mapp’s rule excluding evidence seized in violation of the Fourth Amendment does not apply to state-court convictions that were final before Mapp was decided, so pre-Mapp final convictions remain valid.
- Leaves pre-Mapp final state convictions intact and prevents retrials.
- Applies Mapp to cases pending on direct review and to future prosecutions.
- Avoids reopening thousands of final cases and heavy court administrative burdens.
Summary
Background
A man convicted in Louisiana in 1959 for simple burglary challenged his conviction after this Court decided Mapp v. Ohio in 1961. He had been searched, had keys taken, and police later searched his home and business without a warrant. His state conviction was affirmed in 1960, and his later habeas petitions in state and federal court were denied. The Court of Appeals held Mapp was not retrospective, and the Supreme Court agreed to resolve the split among lower courts.
Reasoning
The Court addressed whether the exclusionary rule announced in Mapp should apply to state convictions that were already final when Mapp was decided. After surveying prior cases and doctrines (including Wolf, Weeks, Elkins, and Schooner Peggy) the majority emphasized the purpose of Mapp: to deter unlawful police searches and to enforce Fourth Amendment protections going forward. The opinion weighed reliance on the prior Wolf rule, the practical impossibility of restoring destroyed evidence or privacy, and the heavy administrative burden of reopening thousands of final cases. For those reasons the Court concluded Mapp does not require reopening convictions that were final before the Mapp decision.
Real world impact
The ruling leaves state-court convictions that were final before June 19, 1961, in place and prevents wholesale reopening of those cases. Mapp still applies to cases pending on direct review at the time it was announced and to future cases. The decision resolves conflicting appeals court rulings by declaring a cutoff at the Mapp opinion date.
Dissents or concurrances
Justice Black, joined by Justice Douglas, dissented, arguing it is unfair to deny relief to prisoners like the Louisiana defendant and that Mapp’s promise should apply to those now in prison.
