John Doe v. Alberto R. Gonzales (originally filed as Doe v. Ashcroft, renamed Doe v. Gonzalez, and finally issued as Doe v. Mukasey) was a case in which the American Civil Liberties Union (ACLU), Library Connection, and several then-pseudonymous librarians, challenged Section 2709 of the Patriot Act; it was consolidated on appeal with a separate case, Doe v. Ashcroft.
