In administrative law, a provision that allows a congressional resolution (passed by a majority of congress, but not signed by the President) to nullify a rulemaking or other action taken by an executive agency. At one time, legislative veto provisions were relatively common, and went along with many congressional delegations of power to administrative agencies (e.g. congress would give the INS power to regulate immigration, but retain the power to overrule any of their decisions by legislative veto). The legislative veto was declared unconstitutional by the Supreme Court in INS v. Chadha, 462 U.S. 919 (1983).
