Whether a federal habeas court must independently determine the constitutional voluntariness of a confession rather than defer to a state court's ultimate finding of voluntariness.
Holding
Yes. Voluntariness is a legal question requiring independent federal appellate determination under the totality of the circumstances.
Reasoning
The Supreme Court's remand established that the ultimate question whether a confession was obtained consistently with the Constitution is not a state factual finding entitled to dispositive deference under 28 U.S.C. § 2254(d). The Third Circuit therefore reviewed the issue anew, while treating the underlying historical facts as part of the record to be evaluated.
The governing inquiry is whether police conduct, considered together with the suspect's characteristics and the circumstances of interrogation, overbore the suspect's will. Psychological pressure can render a confession involuntary, but unlike physical violence it does not trigger a per se rule; the inquiry remains one of totality of the circumstances.
The court stressed that voluntariness is not a but-for causation test. Police questioning commonly helps cause a confession, and permissible psychological tactics may influence a suspect's choice. The constitutional question is whether the tactics deprived the suspect of the capacity to make an autonomous and unconstrained decision to confess.
