Beard v. Banks
The Supreme Court ruled that a death row inmate could not use the 1988 decision in Mills v. Maryland to challenge his death sentence, because Mills announced a new legal rule that did not exist when his conviction became final in 1987.
The decision reinforces strict limits on which new constitutional rules can help people whose convictions are already final, even when the rule addresses a serious risk that a death sentence was reached unfairly.
How it got here: A federal district court denied habeas relief; the Third Circuit reversed and granted relief twice, and Pennsylvania asked the Supreme Court to review the retroactivity question.
The Case in Depth
What happened
A jury convicted George Banks of 12 murders in Pennsylvania and sentenced him to death in the 1980s. Years later, the Supreme Court decided Mills v. Maryland, holding that juries cannot be required to unanimously agree a mitigating factor exists before considering it. Banks argued his jury instructions had the same flaw and sought to have his death sentence overturned using the Mills rule.
The question before the Court
Could a man on death row use a 1988 Supreme Court ruling about jury unanimity on mitigating factors to challenge his 1987 death sentence in federal court?
Why it matters
Death row inmates whose cases became final before a favorable Supreme Court ruling generally cannot use that ruling to reopen their sentences unless the rule was already required by existing precedent or is a rare 'watershed' rule. This keeps most old capital sentences in place even when later cases identify similar flaws in the sentencing instructions used.
What changes now
The case is sent back to the Third Circuit, which must proceed without applying the Mills rule retroactively to Banks's sentence. This is a final merits decision on the retroactivity question, though it leaves unresolved whether the Pennsylvania Supreme Court's separate handling of the Mills claim on state review was itself unreasonable, an issue the Court did not reach.
What this does not decide
The Court did not decide whether Banks's jury instructions actually violated Mills, or whether the Pennsylvania Supreme Court unreasonably applied Mills on the merits. It decided only that the Mills rule is new and does not qualify for either Teague exception, so it cannot be raised on federal habeas review.
Concurrences and dissents
Dissent — Justice Stevens
“A capital sentencing procedure that required the jury to return a death sentence if even a single juror supported that outcome would be the “ ‘ “height of. arbitrariness.” ’ ””The dissent's central objection to letting a single holdout juror control a death sentence.
Justice Stevens argued that Mills was not a new rule but simply a straightforward application of longstanding Eighth Amendment principles against arbitrary and freakish imposition of the death penalty. He reasoned that a single holdout juror controlling a life-or-death decision was always obviously unconstitutional, so applying Mills to Banks's 1987 sentence does not violate Teague, and he would affirm the Third Circuit's grant of relief.
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 a rule's role in ensuring accurate death sentences and less weight to the finality interests of the state, since Mills protected against a particularly serious kind of sentencing error.
How the Court got there
The legal reasoning, step by step
- The Court applied the three-step retroactivity framework from Teague v. Lane, which asks when a conviction became final, whether the legal landscape at that time already required the later rule, and if not, whether either of two narrow exceptions to nonretroactivity applies.
- The Court found Banks's conviction became final in 1987, rejecting his argument that a state court's discretionary practice of overlooking procedural defaults changed the finality date for federal habeas purposes.
- Applying the 'reasonable jurist' test, the Court asked whether the Mills rule -- barring jury instructions that require unanimous agreement on a mitigating factor -- was already compelled by earlier cases like Lockett v. Ohio and Eddings v. Oklahoma, which protected the sentencer's ability to consider mitigating evidence generally.
- The Court concluded that Mills marked a new shift in focus from barriers facing the whole jury to the conduct of individual holdout jurors, a distinction that reasonable jurists -- including dissenting Justices in Mills and McKoy itself -- had disagreed about, showing the rule was not dictated by existing precedent.
- Because Mills announced a new rule, the Court then asked whether it fit either Teague exception for retroactive application, finding it did not forbid punishing certain conduct and was not a rare 'watershed' rule on the level of the right to counsel recognized in Gideon v. Wainwright.
- The Court held that the Mills rule works only an incremental improvement in sentencing accuracy rather than a fundamental change to basic fairness, so it does not qualify for either exception and cannot be applied retroactively on federal habeas review.
Doctrinal impact
Cases affected by this decision
Distinguishes Mills v. Maryland (486 U. S. 367)
The Court treats Mills as a new rule distinct from earlier cases, limiting its retroactive reach on habeas review.
Limits Lockett v. Ohio (438 U. S. 586)
The Court holds Lockett's protection of mitigating evidence did not extend to individual holdout jurors before Mills.
Reaffirms Gideon v. Wainwright (372 U. S. 335)
Used as the benchmark for the rare 'watershed' rules that qualify for retroactive application, which Mills does not meet.
