The Supreme Court has ruled former Attorney General John Ashcroft cannot be personally sued for the wrongful detention of an innocent Muslim-American man. Abdullah al-Kidd sued Ashcroft after being jailed for 15 nights under the federal material witness statute before being released without charge. A federal appeals court had ruled Ashcroft circumvented the Constitution after the 9/11 attacks to hold al-Kidd and other innocent men without charge. But on Tuesday, the Supreme Court unanimously ruled Aschroft is free of liability. Despite rejecting Kidd’s suit, Justice Anthony Kennedy wrote it remains “unresolved whether [Aschroft’s] use of the material witness statute was lawful.”
