Whether a convincing claim of actual innocence can permit review of an otherwise untimely first federal habeas petition under AEDPA's one-year statute of limitations.
Holding
Yes. A credible showing of actual innocence operates as an equitable gateway through AEDPA's statute of limitations for a first federal habeas petition.
Reasoning
The Court treated Perkins' argument as a request for an equitable exception based on a fundamental miscarriage of justice, not as a request for equitable tolling. Equitable tolling requires both diligence and an extraordinary circumstance preventing timely filing; Perkins could not meet that test. The actual-innocence gateway, by contrast, addresses the distinct injustice of allowing a constitutional error to leave an innocent person incarcerated.
The Court's habeas decisions had long allowed a sufficiently persuasive innocence showing to overcome procedural obstacles, including procedural default, abusive petitions, and state filing deadlines. That exception reflects habeas courts' equitable responsibility to prevent constitutional errors from producing the imprisonment of innocent persons. The Court saw no reason that responsibility should disappear merely because the obstacle is AEDPA's federal limitations period.
AEDPA's text did not clearly displace this traditional equitable authority. Section 2244(d)(1)(D) establishes a one-year period running from the date new factual predicates could have been discovered with due diligence, but it governs the ordinary newly discovered-evidence case and requires no proof of innocence. The actual-innocence gateway, by contrast, applies only to the extraordinary case in which new evidence makes it more likely than not that no reasonable juror would have convicted.
The Court rejected Michigan's argument that AEDPA's provisions governing second-or-successive petitions and evidentiary hearings impliedly foreclosed an innocence exception here. Those provisions expressly impose stricter innocence and diligence requirements in their particular contexts. Their inclusion showed that Congress chose to modify the miscarriage-of-justice rule for those contexts, not that Congress eliminated the established gateway for an untimely first petition.
The Court also found it anomalous to give a federal filing deadline greater force than a comparable state deadline. Under existing precedent, actual innocence can excuse a state procedural default based on a state timeliness rule. Interpreting AEDPA to bar the same exception for its own deadline would be difficult to reconcile with AEDPA's aims of federalism and comity.
