Whether Batson v. Kentucky applies to state and federal criminal cases that were pending on direct review or not yet final when Batson was decided.
Holding
Yes. A new constitutional rule governing criminal prosecutions applies to every state or federal case pending on direct review or not yet final when the rule is announced.
Reasoning
The Court distinguished convictions on direct review from convictions already final. In United States v. Johnson, the Court had moved away from the older Linkletter-Stovall practice of deciding retroactivity case by case for both categories. A case is final only when judgment has been rendered, appellate review has been exhausted, and the time to seek certiorari has expired or a certiorari petition has been denied.
Applying current constitutional law to pending cases follows from the judicial role. The Court announces constitutional rules while resolving actual cases and controversies; it does not legislate rules prospectively for the future. Once the Court identifies the governing constitutional principle in one case, the integrity of adjudication requires lower courts to apply that principle to comparable cases still in the direct-review pipeline.
The rule also prevents arbitrary unequal treatment among similarly situated defendants. Batson and Griffith, for example, were tried in the same Kentucky court only months apart and involved the same prosecutor. It would be unfair for Batson alone to receive the benefit of the constitutional rule merely because his case happened to reach the Supreme Court first.
