301 U.S. 1 (1937) (U.S. Supreme Court)
NLRB v. Jones & Laughlin Steel Corp.
Does Congress, under the Commerce Clause, have the authority to regulate intrastate labor relations—including prohibiting discriminatory discharges for union activity—when those activities have a close and substantial relation to interstate commerce, and is the NLRA constitutional as applied to Jones & Laughlin Steel?
Congress may regulate intrastate activities when they have such a close and substantial relation to interstate commerce that their control is essential or appropriate to protect commerce from burdens and obstructions. The NLRA validly protects employees' rights to self-organization and collective bargaining and prohibits employer practices that interfere with those rights where the practices affect interstate commerce.
Yes. The Supreme Court upheld the constitutionality of the NLRA as applied to Jones & Laughlin Steel, holding that labor relations in a large manufacturing enterprise that ships and receives goods in interstate commerce bear a close and substantial relation to interstate commerce. The NLRB's order requiring reinstatement with back pay was enforceable.
Jones & Laughlin is a cornerstone of modern Commerce Clause doctrine and federal labor law. It validated the NLRA's core architecture, established the "close and substantial relation" test for assessing federal power over intrastate activity, and marked the constitutional acceptance of the New Deal regulatory state. The decision paved the way for broad federal regulation of the national economy in cases like United States v. Darby, Wickard v. Filburn, and later jurisprudence upholding federal authority over activities substantially affecting commerce. For labor law, the case entrenched federal protection of the rights to organize and bargain collectively and confirmed the NLRB's remedial powers. For constitutional law, it signaled a decisive shift away from formalistic categorizations toward functional, effects-based analysis—an approach that still shapes debates over the scope of the Commerce Clause, even as modern cases (e.g., Lopez and Morrison) delineate its outer limits.
