Linkletter v. Walker
The Court ruled that its 1961 decision in Mapp v. Ohio, which required state courts to exclude illegally seized evidence, would not reopen convictions that had already become final before Mapp was decided.
The ruling established that the Constitution neither requires nor forbids applying new rulings retroactively, letting the Court weigh a decision's purpose and the disruption of reopening old cases before deciding whether to apply it to closed convictions.
How it got here: Louisiana courts denied Linkletter's post-Mapp habeas petition; a federal district court also denied relief, and the Fifth Circuit affirmed, prompting Supreme Court review.
The Case in Depth
What happened
Victor Linkletter was convicted of burglary in Louisiana in 1959 after police, without a warrant, searched his home and business and seized evidence used against him. His conviction became final in 1960, before the Supreme Court's 1961 ruling in Mapp v. Ohio required state courts to exclude illegally obtained evidence. After Mapp, Linkletter sought habeas corpus relief, arguing the new exclusionary rule entitled him to a new trial.
The question before the Court
After the Supreme Court ordered states to exclude illegally seized evidence, did that new rule also free people whose convictions were already final before the ruling?
The Court's answer
No — the Court ruled that the exclusionary rule from Mapp v. Ohio does not reach back to free people whose convictions were already final when Mapp was decided in 1961. The Constitution does not require or forbid retroactive application of a new ruling, so the Court weighed the rule's purpose, the reliance placed on the old rule, and the burden of reopening old cases.
Because the exclusionary rule exists to deter future police misconduct rather than to ensure a trial's factual reliability, and because reopening final convictions would disrupt the administration of justice without correcting past wrongs, the Court held that Mapp applies only to cases still on direct appeal when it was decided, not to convictions that were already final.

Why it matters
People convicted using illegally seized evidence before June 1961 stayed in prison, even though the same evidence could not be used against someone tried today. The decision gave courts a flexible framework for deciding whether future constitutional rulings should reopen old convictions, shaping how courts handled landmark criminal-procedure rule changes for decades afterward.
What changes now
The ruling is final on the merits: Linkletter's conviction stands, and defendants whose convictions became final before June 19, 1961, cannot use Mapp v. Ohio to challenge illegally obtained evidence used against them. Going forward, the case supplied the framework - weighing a new rule's purpose, reliance on the old rule, and the burden of reopening cases - that later decisions used to decide whether other new constitutional rulings applied retroactively.
What this does not decide
The Court did not hold that new constitutional rules can never apply retroactively; it left open that rules protecting the fairness of the trial itself, like the ban on coerced confessions, could still reach old, final convictions. The decision addressed only the search-and-seizure exclusionary rule announced in Mapp v. Ohio.
Concurrences and dissents
Dissent — Justice Black
“Linkletter must stay in jail; Miss Mapp, whose offense was committed before Linkletter's, is free.”Black argued the ruling created an arbitrary and unjust result between similarly situated defendants.
Justice Black argued the majority's ruling produced an arbitrary and unjust result, denying Linkletter relief while Miss Mapp went free despite committing her crime earlier. He argued the exclusionary rule protects defendants' constitutional rights, not merely serves as a punitive deterrent against police, and that the Mapp rule should apply to anyone still imprisoned on unconstitutionally obtained evidence, just as coerced-confession rulings had been applied retroactively in earlier cases.
How the Court got there
The legal reasoning, step by step
- The Court explained that the Constitution itself neither compels nor forbids giving a new judicial ruling retroactive effect - the choice is a matter of judicial policy rather than constitutional command, quoting Justice Cardozo's view that 'the federal constitution has no voice upon the subject.'
- Because retroactivity is optional, the Court said it must weigh each new rule separately by examining the rule's purpose, how much people relied on the old rule, and how much reopening old cases would burden the administration of justice.
- Applying that balancing test to the exclusionary rule from Mapp v. Ohio, the Court found its purpose was to deter future police misconduct, not to fix unreliable trials - unlike rules such as the ban on coerced confessions, which go to whether a trial's fact-finding process was trustworthy.
- The Court reasoned that reopening final convictions to enforce a deterrence-focused rule would do nothing to undo past police misconduct or restore violated privacy, since deterrence only operates going forward.
- The Court also weighed the practical burden of retroactive application, noting that reopening old search-and-seizure claims would require hearings on evidence and witnesses that might no longer be available, straining the courts for little corresponding benefit.
- Balancing these factors, the Court concluded that the date of the Mapp decision, not the date of the original search, was the proper dividing line between cases entitled to the new rule and those governed by the old one.
