Duncan v. Walker

Background

A New York prisoner challenged several robbery convictions and filed a federal habeas petition shortly before AEDPA's one-year deadline. The federal district court dismissed that petition without prejudice for failing to show that state remedies were exhausted. The prisoner later filed another federal petition that was ruled time barred, and the Second Circuit held the earlier federal filing paused (tolled) the one-year limit.

Reasoning

The Court examined the wording of 28 U.S.C. § 2244(d)(2) and concluded that the word "State" applies to the whole phrase "post-conviction or other collateral review," so only state, not federal, collateral proceedings toll AEDPA's one-year limit. The majority relied on how Congress used "State" and "Federal" elsewhere in the law, the need to give effect to each word, and policy goals like comity, finality, and encouraging exhaustion of state remedies. The Court therefore reversed the Second Circuit and held the earlier federal petition did not pause the clock.

Real world impact

The decision means prisoners cannot count time spent pursuing a defective federal habeas petition toward AEDPA's one-year limit; they must act quickly to cure defects or return to state court. The ruling increases risks for pro se prisoners who file mixed or unexhausted federal petitions and places pressure on district courts and litigants to use procedures like stays or equitable tolling to avoid unfair losses of review rights. The Court did not resolve whether courts may apply equitable tolling in particular cases.

Dissents or concurrances

A dissent argued the phrase reasonably includes federal petitions and warned the ruling would unfairly bar many claims; two concurring opinions stressed that district courts may stay proceedings or apply equitable tolling in appropriate cases to prevent injustice.
