Whether a habeas petitioner abuses the writ only by deliberately abandoning a claim, or also by failing to raise it earlier through inexcusable neglect.
Holding
A petitioner may abuse the writ through inexcusable neglect; deliberate abandonment is not required. The governing standard is cause and prejudice, subject to a narrow fundamental-miscarriage-of-justice exception.
Reasoning
The Court traced the historical development of abuse-of-the-writ doctrine. Although habeas denials traditionally did not have strict res judicata effect, courts acquired discretion to reject repetitive or piecemeal applications once appellate review became available. Decisions such as Salinger, Wong Doo, Price, and Sanders established that a petitioner’s conduct could disentitle him to relief when he withheld or failed to pursue a claim that should have been raised earlier.
Section 2244(b) and Habeas Rule 9(b) allow dismissal of later petitions that raise new claims when the petitioner deliberately withheld the claim or otherwise abused the writ. The Court read the phrase “otherwise abused the writ” to preserve judicial authority to identify abuse beyond intentional abandonment, including failure to raise an available claim through inexcusable neglect.
The Court concluded that abuse of the writ and state procedural default serve closely related purposes. Both require prisoners to comply reasonably with procedural rules; both protect the finality of criminal judgments; both reduce the costs imposed on States and federal courts by delayed collateral litigation; and both discourage strategic withholding of claims.
Accordingly, the Court imported the procedural-default rule of cause and prejudice. Once the State pleads abuse with clarity and particularity by identifying the prior petition and the newly asserted claim, the prisoner must show cause—an objective external impediment that prevented earlier presentation—and actual prejudice. Attorney error short of constitutionally ineffective assistance is not cause.
Even without cause, a court may hear the otherwise barred claim only in the narrow circumstance where refusing review would produce a fundamental miscarriage of justice—ordinarily, where a constitutional violation probably caused the conviction of an innocent person. This exception gives substantive meaning to the older “ends of justice” formulation.
