Brown v. Payton
The Supreme Court reversed a federal appeals court ruling that had thrown out a California death sentence over jury instructions on mitigating evidence. The Court held that under the strict limits Congress placed on federal habeas review, it was not unreasonable for California's courts to conclude the jury could still consider the defendant's claimed prison religious conversion.
The decision reinforces how much deference federal courts must give state court rulings in habeas cases, even where the trial court's handling of jury instructions and a prosecutor's misleading argument might have been questionable.
“It was not unreasonable for the state court to determine that the jury most likely believed that the evidence in mitigation, while within the reach of the factor (k) instruction, was simply too insubstantial to overcome the arguments for imposing the death penalty”
The Court's conclusion that the state court reasonably read the jury's likely view of the mitigating evidence.
How it got here: The California Supreme Court affirmed the death sentence; after federal habeas proceedings, the Ninth Circuit sitting en banc twice granted relief, and the State sought Supreme Court review.
The Case in Depth
What happened
William Payton raped and murdered a woman at a boarding house and attacked two others with a knife. At his capital sentencing, the defense presented evidence that Payton had undergone a sincere religious conversion in the roughly two years since his arrest, while the prosecutor argued the jury instructions did not allow consideration of anything happening after the crime, including that conversion.
The question before the Court
Was a California death-row inmate's trial unfair because jurors might have been told, wrongly, that they could not weigh his prison religious conversion as a reason to spare his life?
The Court's answer
No — the Supreme Court ruled that the state courts' handling of the case was not unreasonable enough to justify federal habeas relief, even though the trial was imperfect. The prosecutor wrongly told jurors they could not consider Payton's prison religious conversion, and the trial judge never directly corrected that error. But under the deferential federal habeas standard, the question was not whether the state court's decision was right, only whether it was objectively unreasonable.
Because the jury was told to consider all the trial evidence and was never explicitly instructed to disregard the conversion evidence, the Court found it reasonable for California's courts to conclude the jury likely still weighed that evidence, just found it insufficient to outweigh the aggravating facts of the crime. So the Ninth Circuit's grant of habeas relief was reversed.

Why it matters
The ruling makes clear that federal courts reviewing state death sentences cannot overturn a state court's judgment call just because they might have decided differently; the state decision must be objectively unreasonable, not merely incorrect. This raises the bar for death-row inmates nationwide seeking federal habeas relief based on jury-instruction errors.
What changes now
The Supreme Court's reversal restores the state court's original affirmance of Payton's death sentence, ending the federal habeas relief the Ninth Circuit had granted. This is a final merits decision resolving the habeas claim under the governing statute; it does not address whether the trial's handling of the mitigation instruction would have violated the Constitution under a non-deferential standard.
What this does not decide
The Court did not decide whether the jury instructions and prosecutor's argument actually violated the Eighth Amendment. It decided only that the state court's contrary conclusion was not objectively unreasonable under the deferential federal habeas standard, leaving open how the issue might come out on direct review.
Concurrences and dissents
Concurrence — Justice Scalia
Justice Scalia agreed the state court's decision survived deferential habeas review, but wrote separately to reiterate his broader view that limiting a jury's discretion to consider all mitigating evidence does not violate the Eighth Amendment at all, a position he has held independent of the habeas deference question.
Concurrence — Justice Breyer
Justice Breyer said that if he were a California judge he would likely find the penalty proceedings violated the Eighth Amendment, given the prosecutor's repeated misstatements and the ambiguity of factor (k). But he joined the majority because federal habeas deference required leaving the state court's contrary, though debatable, conclusion in place.
Dissent — Justice Souter
“There is no more room here to doubt the reasonable possibility that Payton's jurors failed to consider the postoffense mitigation evidence that the Constitution required them to consider.”Souter's central objection that the jury was likely misled into ignoring the conversion evidence.
Justice Souter argued the prosecutor repeatedly and wrongly told the jury it could not consider Payton's religious conversion, the trial judge never corrected this, and the final instructions reinforced the error by excepting certain evidence from consideration. He concluded the state court unreasonably applied Boyde and that the Ninth Circuit's grant of habeas relief should stand.
How the Court got there
The legal reasoning, step by step
- Under the federal habeas statute, a federal court may only overturn a state court's ruling if it was 'contrary to' or involved an 'unreasonable application of' clearly established Supreme Court precedent -- meaning the state court's error, if any, must go beyond ordinary mistake to be objectively unreasonable.
- The Court looked to its earlier decision in Boyde v. California, which had already upheld the same catchall mitigation instruction (factor (k)) against a claim that it excluded consideration of a defendant's background and character.
- The Court found it was not unreasonable for the California Supreme Court to extend Boyde's reasoning to postcrime evidence like a religious conversion, since Boyde's logic covered any circumstance that might excuse or lessen a crime, and remorse -- which can only arise after a crime -- has long been understood to reduce culpability.
- Applying Boyde's test of whether there is a 'reasonable likelihood' the jury misunderstood the instructions in light of the whole trial record, the Court concluded it was not unreasonable for the state court to find the jury still could have considered the conversion evidence, given that the trial judge instructed jurors to consider all evidence and never told them to disregard it.
- Because the state court's application of Boyde was, at most, merely incorrect rather than objectively unreasonable, the conditions required for federal habeas relief under the deferential statute were not met.
