Whether the Supreme Court could independently review the facts surrounding the confessions even though a Florida jury had resolved the factual issues against the petitioners.
Holding
Yes. Because the petitioners timely asserted a federal due-process right, the Court had to independently examine the facts necessary to determine whether their confessions were constitutionally obtained.
Reasoning
A state jury's finding did not conclusively settle the federal constitutional question. The use of an improperly obtained confession can itself deny due process under the Fourteenth Amendment, so the Court was required to look behind the state judgments and assess the circumstances in which the confessions were secured.
The Court followed its approach in earlier coerced-confession and racial-discrimination cases: when a federal constitutional guarantee depends on the actual facts, the Supreme Court must make an independent determination rather than simply defer to a state factfinder's conclusion.
