Swarthout v. Cooke
The Supreme Court summarily reversed the Ninth Circuit, ruling that federal habeas courts cannot second-guess whether California courts correctly applied California's own "some evidence" standard for denying parole.
The decision makes clear that the federal Due Process Clause only guarantees a prisoner a chance to be heard and a statement of reasons for a parole denial — not a federal review of whether the state's evidentiary standard was correctly applied to the facts.
How it got here: State courts denied habeas relief to both men; federal district courts and the Ninth Circuit then granted or upheld habeas relief, prompting California to seek Supreme Court review.
The Case in Depth
What happened
Two California prisoners serving indeterminate life sentences, Damon Cooke and Elijah Clay, were each denied parole \u2014 Cooke by the parole board, Clay by the Governor after the board had found him suitable. Both argued that the record lacked the "some evidence" required under California law to find them still dangerous, and both sought federal habeas relief after losing in state courts.
The question before the Court
When a state's own parole rules require "some evidence" before denying parole, can a federal habeas court step in if it thinks a state court misapplied that rule?
Why it matters
California prisoners denied parole can no longer rely on federal habeas courts to re-examine whether state parole boards or courts got the "some evidence" call right. The ruling narrows the avenues open to thousands of California inmates challenging parole denials and reins in the Ninth Circuit's practice of reviewing those state-law determinations on the merits.
What changes now
The judgments of the Ninth Circuit are reversed, meaning Cooke and Clay's parole denials stand. The ruling forecloses similar federal habeas challenges based solely on whether California's "some evidence" standard was correctly applied, leaving that responsibility to California's own courts. This is a final, though summary, resolution of the legal question, decided without full briefing or oral argument.
What this does not decide
The Court did not decide whether California law actually creates a constitutionally protected liberty interest in parole, treating the Ninth Circuit's assumption as reasonable without endorsing it. It also did not decide whether the "some evidence" standard was actually satisfied in either prisoner's case.
Concurrences and dissents
Concurrence — Justice Ginsburg
Justice Ginsburg noted that if California law actually entitled prisoners to parole once they met specified criteria, a stricter due-process standard from a good-time-credits case might apply instead. But because the Ninth Circuit itself had already determined that California's parole system is governed by the more lenient Nebraska-style precedent, she agreed the summary reversal was appropriate.
How the Court got there
The legal reasoning, step by step
- The Court explained that federal habeas relief is only available for violations of federal law, not for a state court's mistaken application of its own state-law rules — a federal habeas statute requirement that has long barred relief for mere errors of state law.
- Applying due-process analysis, the Court asked first whether a liberty interest existed and, if so, whether the state provided constitutionally adequate procedures to protect it — a two-step framework used to decide how much process is due.
- The Court accepted, without deciding, that California's parole statute creates a liberty interest in parole, but held that once such an interest exists, the Constitution requires only minimal procedures: an opportunity to be heard and a statement of reasons for denial, as established in an earlier case about Nebraska's parole system.
- Because Cooke and Clay were allowed to speak at their hearings, contest the evidence, access records in advance, and receive reasons for their denials, the Court concluded they received all the process the Constitution demands.
- The Court rejected the Ninth Circuit's view that California's "some evidence" rule was itself part of the federally protected liberty interest, reasoning that treating a state's own evidentiary procedure as a federal requirement would improperly open all state procedural rules to federal merits review.
