The United States Supreme Court delivered a landmark 6-3 victory for American businesses on Tuesday by restricting activist lawsuits under international statutes. In Cisco Systems, Inc. v. Doe, the justices ruled that neither the Alien Tort Statute nor the Torture Victim Protection Act permits private plaintiffs to sue companies for aiding alleged international law violations.

Justice Amy Coney Barrett authored the majority opinion, emphasizing that courts lack the constitutional authority to create new private causes of action for international norms. The ruling decisively curtails decades of expansive judicial activism that allowed foreign claimants to target American corporations operating in global markets through domestic courts.

This high court decision strongly reinforces the separation of powers across the federal government. The majority opinion makes clear that establishing foreign policy remedies and regulating international conduct strictly belongs to Congress and the executive branch, rather than unelected federal judges utilizing ambiguous tort statutes.
