Whether Stone v. Powell bars federal habeas review of a Sixth Amendment ineffective-assistance claim when counsel's alleged error was failing to litigate a Fourth Amendment suppression claim.
Holding
No. Stone does not bar federal habeas review of a distinct ineffective-assistance-of-counsel claim, even when the underlying attorney error concerns a Fourth Amendment suppression issue.
Reasoning
A Fourth Amendment claim and a Sixth Amendment ineffective-assistance claim protect different interests and require different proof. A Fourth Amendment claim challenges an unlawful government search or seizure. An ineffective-assistance claim challenges counsel's deficient performance and requires a showing that the deficiency created a reasonable probability of a different result. When the asserted deficiency is failure to pursue suppression, the petitioner must also establish that the suppression claim was meritorious, but that Fourth Amendment issue is only one element of the separate Sixth Amendment claim.
Stone restricted federal habeas review of Fourth Amendment exclusionary-rule claims because exclusion is a judicially created deterrent remedy, not a personal constitutional entitlement, and collateral review adds little deterrent value relative to its costs. Morrison instead sought protection of his personal Sixth Amendment right to effective counsel, a right essential to a fair and legitimate adversarial process. Stone itself carefully limited its rule to the exclusionary rule and did not generally restrict habeas review of constitutional claims.
Collateral review is often the first realistic opportunity for a defendant to discover and litigate ineffective assistance. A defendant ordinarily cannot recognize counsel's professional failures during trial or while represented by the same lawyer on appeal. Extending Stone would therefore deprive many defendants of any meaningful opportunity to vindicate their right to effective trial or appellate counsel.
The Sixth Amendment places the risk of constitutionally inadequate representation on the State. The Court rejected the argument that counsel's failure to suppress reliable evidence cannot cause cognizable prejudice merely because exclusion might impede truthfinding. Effective assistance belongs to guilty and innocent defendants alike, and its availability does not depend on a showing of actual innocence.
Allowing these claims does not make Stone meaningless. Strickland imposes a demanding standard: the petitioner must overcome the presumption that counsel acted reasonably, show that the unlitigated Fourth Amendment claim was meritorious, and establish a reasonable probability that the outcome would have differed without the excluded evidence. A viable Fourth Amendment claim alone is not enough for habeas relief.
