Beard v. Banks
The Supreme Court ruled that a man sentenced to death in Pennsylvania could not rely on a later Supreme Court decision, Mills v. Maryland, to challenge his death sentence in federal court, because that decision announced a new legal rule that did not exist when his case became final.
The ruling reinforces strict limits on which new constitutional rules can help people who already exhausted their appeals get relief through federal habeas corpus, reserving that avenue for only the narrowest categories of rule changes.
How it got here: A federal district court denied habeas relief; the Third Circuit reversed twice, and the Supreme Court reviewed the Third Circuit's second ruling granting relief.
The Case in Depth
What happened
George Banks was convicted of 12 first-degree murders and sentenced to death in Pennsylvania. His conviction became final in 1987. Months later, the Supreme Court decided Mills v. Maryland, ruling that juries cannot be required to unanimously agree on a mitigating factor before considering it. Banks argued his jury instructions had the same unconstitutional unanimity problem and sought relief in state and then federal court.
The question before the Court
Could a death-row inmate whose case became final in 1987 use a later Supreme Court ruling about juror unanimity on mitigating evidence to challenge his sentence on federal habeas review?
Why it matters
The decision makes it harder for death-row and other prisoners whose convictions are already final to benefit from later Supreme Court rulings that expand protections, even rulings addressing arbitrary application of the death penalty. It reaffirms that federal courts must screen new constitutional rules through a strict retroactivity test before granting habeas relief, keeping most old convictions insulated from new legal developments.
What changes now
The case returns to the lower courts, but with the Mills rule unavailable to Banks on habeas review, his death sentence challenge on that basis cannot succeed. The decision does not resolve whether the Pennsylvania Supreme Court had otherwise misapplied Mills, since the Court found that question unnecessary to reach. The ruling stands as a final merits decision guiding how courts apply the Teague retroactivity framework in future capital habeas cases.
What this does not decide
The Court did not decide whether the Pennsylvania Supreme Court had reasonably applied Mills to Banks's actual jury instructions and verdict form, since it found that question unnecessary once it concluded Mills could not apply retroactively at all.
Concurrences and dissents
Dissent — Justice Stevens
Justice Stevens argued that Mills did not announce a new rule at all, but simply applied the longstanding Eighth Amendment principle against arbitrary and freakish imposition of the death penalty. He contended that letting a single juror's vote control a death sentence was always understood to be unconstitutional, so Banks should be able to raise the claim on habeas review, and he would have affirmed relief for Banks.
Dissent — Justice Souter
Justice Souter joined Stevens's dissent but wrote separately to connect the case to Justice Breyer's dissent in a companion case, arguing that the reasonable-jurist standard used to judge whether a rule is 'new' should give more weight to accuracy in capital sentencing and less to finality. He would have found Mills's protection against an arbitrary lone-juror veto was not new and would have affirmed.
How the Court got there
The legal reasoning, step by step
- The Court applied the three-step framework from Teague v. Lane for deciding whether a new constitutional rule can be used on federal habeas review: first fix the date the conviction became final, then ask whether existing precedent at that time already required the rule, and finally check whether any exception to the bar on new rules applies.
- The Court rejected the argument that Pennsylvania's past practice of sometimes excusing procedural default in capital cases changed the finality date, holding that a state court's discretionary willingness to overlook waiver does not make an otherwise-final conviction non-final for retroactivity purposes.
- Examining the legal landscape as of 1987, the Court found that earlier cases like Lockett v. Ohio and Eddings v. Oklahoma had barred obstacles to a jury's ability to consider mitigating evidence, but none of those cases addressed whether individual holdout jurors could block consideration of a mitigating factor.
- Because reasonable judges could and did disagree — as shown by dissents in Mills and McKoy v. North Carolina itself — about whether the Lockett line of cases actually required the individual-juror rule, the Court concluded Mills broke new ground rather than being compelled by existing precedent, making it a new rule under Teague.
- The Court then found that Mills did not qualify for either of Teague's two exceptions, since it did not bar punishment of certain conduct and was not a watershed rule on the level of the right to counsel recognized in Gideon v. Wainwright, because it worked only a narrow, incremental change rather than a fundamental shift in criminal procedure.

Limits Mills v. Maryland (486 U. S. 367)
Held that this ruling announced a new rule that cannot be applied retroactively to cases already final before it was decided.

Cited as the model for the rare kind of watershed rule that can apply retroactively, unlike the Mills rule.
