Campbell v. Clinton
United States Court of Appeals for the District of Columbia Circuit
203 F.3d 19 (D.C. Cir. 2000)
President Clinton ordered U.S. military participation in NATO airstrikes against Yugoslavia in 1999, reporting to Congress within 48 hours and asserting authority as Commander in Chief; Congress voted against declaring war or authorizing the strikes but also declined to require an immediate end to U.S. involvement and voted to fund the operation. Several members of Congress sued, claiming Clinton violated the War Powers Resolution and the Constitution's War Powers Clause by acting without congressional authorization; the district court found the congressmen lacked standing.
Whether individual members of Congress have standing to sue the President for allegedly violating the War Powers Resolution and the constitutional War Powers Clause by ordering military action without a declaration of war or specific authorization.
