Caterpillar Inc. v. Williams

Background

A group of long‑time Caterpillar employees says the company promised them indefinite, lasting jobs and breached those individual employment contracts after downgrading positions and announcing the San Leandro plant’s closure. Many had been promoted out of hourly union jobs into managerial or weekly salaried roles. They sued in California state court for breach of their individual contracts. Caterpillar removed the case to federal court, arguing the individual contracts were superseded by the union collective-bargaining agreement and therefore governed by federal labor law. The District Court allowed removal and dismissed the suit; the Ninth Circuit reversed, and the Supreme Court granted review and now affirms the Ninth Circuit.

Reasoning

The Court explained that a plaintiff may choose state law and keep a case in state court unless the complaint on its face presents a federal cause of action. Only in rare cases does a federal statute “completely pre-empt” state law and turn a state claim into a federal one. Section 301 of the federal labor law does pre-empt claims founded on collective-bargaining agreements or claims that require heavy interpretation of those agreements. But these employees sued on separate individual contracts that the Court found were not substantially dependent on the collective agreement. A defendant’s defensive argument that federal law might ultimately prevail does not by itself allow removal to federal court.

Real world impact

This decision keeps these kinds of individual employment-contract disputes in state court. Employers may still assert federal-labor defenses or arbitration issues in state court or before labor agencies, but those defenses do not automatically shift the case into federal court. The Court left the actual merits of the contract and pre-emption defenses for the state courts to decide.
