Garmon Doctrine Law and Legal Definition

Garmon Doctrine is a principle of Labor law. This doctrine prohibits the state regulation of activities that are actually or arguably protected by the rules of National Labor Relations Act relating to the right of employees to organize and bargain collectively, or prohibited by the provisions of National Labor Relations Act's provision that governs unfair labor practices. This standard was set by the U.S. Supreme Court in SAN DIEGO BLDG. TRADES COUNCIL v. GARMON, 359 U.S. 236 (U.S. 1959) where the court held that state regulations and causes of action are preempted when they concern an activity that is actually or arguably protected or prohibited by the NLRA. The state claim may survive, however, if the conduct at issue is of only peripheral concern to the federal law or touches interests so deeply rooted in local feeling and responsibility.

Garmon Doctrine is also called Garmon Preemption.
