The U.S. Supreme Court ruled 6-3 that federal laws do not permit private lawsuits against companies for aiding international law violations.

The U.S. Supreme Court issued a landmark 6-3 ruling on Tuesday in Cisco Systems, Inc. v. Doe, restricting judicial power over international disputes. The majority opinion established that neither the Alien Tort Statute nor the Torture Victim Protection Act permits private plaintiffs to pursue aiding-and-abetting claims against American companies operating abroad.
