U.S. lawsuits for overseas abuses

In brief
The Court kept the appeals court’s ruling in place because the Alien Tort Statute does not override the usual rule against applying U.S. law to conduct abroad; it left corporate liability unanswered.

Summary: written with AI from the case record.

What it's about
The Supreme Court left the appeals court’s ruling in place, applying the usual assumption that U.S. law does not cover conduct abroad; it did not decide whether companies can be sued under the statute.
The Alien Tort Statute lets federal courts consider certain claims by foreign nationals alleging violations of international law.
Question presented
1. Under the Alien Tort Statute, are corporations immune from tort liability for violations of the law of nations, such as torture, extrajudicial executions, or genocide? 2. Upon reargument, does the Alien Tort Statute allow courts to recognize a cause of action for violations of the law of nations occurring within the territory of a sovereign other than the United States?
What the Court decided
Holding
The presumption against extraterritoriality applies to claims under the ATS, and nothing in the statute rebuts that presumption. 621 F. 3d 111, affirmed.
- Result
- Affirmed
The Court's reasoning
The Court said the Alien Tort Statute does not overcome the usual presumption that U.S. law does not govern conduct abroad. It also said a claim needs a strong enough connection to U.S. territory to get past that rule; a company’s mere presence in the United States is not enough.
