National Emergency
A national emergency is a formal declaration by the President that activates standby statutory powers Congress has tied to such a declaration. The National Emergencies Act of 1976 (P.L. 94-412, 50 U.S.C. §§ 1601-1651) ended the then-existing declared emergencies and set the modern procedure: the President declares an emergency by proclamation or Executive order published in the Federal Register and transmitted to Congress, and must specify the provisions of law under which the government will act. An emergency expires if the President does not renew it annually, and Congress can terminate it by an enacted joint resolution.

Example: The 1976 Act itself is the clearest case: Congress passed it after a Senate investigation (Senate Report 93-549) found four emergencies still on the books — from 1933, 1950, 1970 and 1971 — and section 1601 terminated all powers that flowed from them.
Common misconception: Declaring a national emergency does not itself create new powers or suspend the Constitution. It only unlocks powers Congress has already written into statute, and the President must cite which ones; an emergency can be ended by the President, by annual lapse, or by Congress.
