Whether § 301(a) of the Labor Management Relations Act merely grants federal jurisdiction, or also authorizes federal courts to enforce collective-bargaining agreements and develop governing substantive law.
Holding
Section 301(a) does more than confer jurisdiction: it authorizes federal courts to fashion and apply federal law to enforce collective-bargaining agreements, including through specific enforcement of an agreement to arbitrate grievances.
Reasoning
Section 301(a) permits suits for violations of labor contracts in federal district court without regard to diversity or the amount in controversy. Section 301(b), which allows unions to sue and be sued as entities and limits judgments to union assets, supplies procedural machinery that would be unnecessary if § 301(a) did no more than create a jurisdictional forum. Read together, the provisions show a congressional purpose to make collective agreements judicially enforceable by and against labor organizations.
The legislative history, though not perfectly clear, showed Congress's concern with making collective agreements binding on both parties and with promoting industrial peace through faithful performance. Congress had considered making refusal to honor arbitration agreements an unfair labor practice, but instead chose to leave enforcement to the ordinary legal process. That choice supported judicial remedies for violations of collective-bargaining agreements.
A promise to arbitrate grievances is the counterpart of a no-strike promise. Enforcing arbitration therefore advances the federal labor policy favoring stable agreements and the peaceful resolution of workplace disputes. Treating § 301 as jurisdictional only would undercut that policy and leave a central contractual promise without an effective federal remedy.
The governing law in a § 301 action is federal law, fashioned from the policies embodied in national labor legislation. Courts may draw on compatible state-law principles where useful, but any such rule is incorporated as federal law rather than applied as an independent source of rights. Congress could regulate these labor-management disputes under the Commerce Clause, so such cases arise under federal law for Article III purposes.
