Sosa v. Alvarez-Machain

Background

A Mexican physician, Humberto Alvarez-Machain, was seized in Mexico and flown to Texas after U.S. Drug Enforcement Administration officials suspected him in a DEA agent’s kidnapping, torture, and murder. Alvarez sued one of his abductors under the Alien Tort Statute and sued the United States under the Federal Tort Claims Act for false arrest. Lower courts split: the Ninth Circuit allowed both claims to proceed, saying U.S. planning at DEA headquarters prevented the FTCA foreign-country exception from applying and that international law forbids arbitrary arrest.

Reasoning

The Supreme Court reversed both rulings. It held that the FTCA’s exception for "any claim arising in a foreign country" bars suits for injuries that occurred abroad, even when U.S. officials planned or directed the conduct from the United States. The Court also concluded that the ATS is only a jurisdictional grant and does not automatically create broad new damage actions; federal courts may recognize a very small set of well-defined international norms, but Alvarez’s claim lacked that specificity and universal acceptance.

Real world impact

The decision prevents Alvarez from recovering money under either statute for his brief detention after the cross-border abduction. It narrows when people can sue the United States for overseas harms and limits private damages suits under the ATS to a few clear, historically grounded international wrongs. The Court urged caution and deference to Congress and the political branches before creating new federal causes of action.

Dissents or concurrances

Several Justices wrote separately: Justice Scalia argued that courts have no power to create new international-law-based causes of action, while Justices Ginsburg and Breyer agreed with parts of the opinion and offered different reasoning on FTCA.
