What the Court decided
Holding
The law enforcement proviso extends to law enforcement officers’ acts or omissions that arise within the scope of their employment, regardless of whether the officers are engaged in investigative or law enforcement activity, or are executing a search, seizing evidence, or making an arrest. The proviso’s plain language supports this conclusion. On its face, the proviso applies where a claim arises out of one of six intentional torts and is related to the “acts or omissions” of an “investigative or law enforcement officer.” §2680(h). 4, reversed and remanded.
- Result
- Reversed
The Court's reasoning
The Court read the law to cover claims tied to a law-enforcement officer’s actions or failures to act within the scope of the job. It said the officer need not be investigating, searching, seizing evidence, or making an arrest.
The vote
What's next
The case returns to the Third Circuit, which must apply the Supreme Court’s rule. Whether the guard qualified as a law-enforcement officer and acted within his job remains unresolved.
