In United States v. Alvarez-Machain (1992), the U.S. Supreme Court held that an extradition treaty with Mexico did not prohibit the U.S. from forcibly abducting a Mexican citizen for trial in the U.S., as the treaty was silent on the issue. This decision was controversial and led to changes in extradition practices.
