Whether a counseled defendant is entitled to federal habeas relief, or even an evidentiary hearing, merely by alleging that a prior coerced confession motivated an otherwise valid guilty plea.
Holding
No. A guilty plea is not subject to collateral attack merely because it was motivated by a confession later alleged to have been coerced; the defendant must also show that counsel's plea advice fell outside the range of competence demanded of criminal defense attorneys, or identify some other basis showing that the plea itself was not voluntary and intelligent.
Reasoning
A guilty plea ordinarily rests on the defendant's own admission in open court, not on evidence the prosecution might have introduced at trial. By pleading guilty, a defendant waives trial and ordinarily waives objections to the admissibility of evidence, so the constitutional question is whether the plea itself was a voluntary and intelligent choice.
A defendant deciding whether to plead faces uncertainty about the strength of the prosecution's case and the admissibility of evidence. Counsel must make predictive judgments about factual disputes and legal rulings, including whether a confession would likely be admitted. The Constitution does not make a plea invalid simply because competent counsel's good-faith prediction later proves mistaken.
Where a defendant pleads guilty because he believes a confession will be admissible, the claim is generally that he and counsel misjudged the confession's admissibility, not that the plea was compelled. A plea based on reasonably competent advice remains intelligent despite ordinary errors in assessing facts or law.
The Court did not hold that all pleas following coerced confessions are immune from challenge. An uncounseled plea, a plea directly tainted by continuing coercive pressure, or a plea resulting from constitutionally deficient legal assistance may still be attacked. But allegations only that a coerced confession existed and influenced the plea do not require a habeas hearing.
