moot.jpeg Because Federal Courts only have constitutional authority to resolve actual disputes (see Case or Controversy) legal actions cannot be brought or continued after the matter at issue has been resolved, leaving no live dispute for a court to resolve. In such a case, the matter is said to be “moot”. For Supreme Court decisions focusing on mootness, see, e.g., Arizonans for Official English v. Arizona, 520 U.S. 43 (1997) and Hicklin v. Orbeck, 437 U.S. 518 (1978). See also Federal courts, Constitutional law
