What it's about
The Supreme Court said it could, agreed with the lower-court judgment, and sent the case back to the lower court (remanded).
The FTCA permits certain claims against the United States but sets deadlines for filing them.
Question presented
1. Whether the FTCA’s filing deadlines are subject to equitable tolling. 2. Whether the deadlines are “jurisdictional” in nature, so that courts are without power to adjudicate claims filed outside their strict limits. 3. if they are not jurisdictional, whether the statute nonetheless prohibits equitable tolling.
What the Court decided
Holding
Section 2401(b)’s time limits are subject to equitable tolling. 505, affirmed and remanded.
