Mesa v. California

Background

Two mailtruck drivers employed by the United States Postal Service in Santa Clara County, California, were charged in state court with traffic-related crimes after separate collisions—one involving a fatality and the other a collision with a police car. The United States Attorney filed petitions to remove those criminal prosecutions to federal district court under the federal officer removal statute. The Ninth Circuit ordered the cases remanded to state court, and the Supreme Court agreed to resolve the scope of removal and has now affirmed the Court of Appeals.

Reasoning

The Court framed the core question as whether a federal employee may move a state criminal prosecution to federal court without alleging a federal defense tied to official duties. After reviewing a long line of precedents, the Court concluded that removal under the statute must be based on the allegation of a colorable federal defense connected to the officer’s duties. The opinion explained that the statute is jurisdictional and cannot by itself create the federal question needed for federal-court review, and that permitting removal without any federal defense would raise serious constitutional and federalism concerns. The Government’s broader reading of the statute was rejected.

Real world impact

The decision means routine traffic prosecutions of federal employees will normally proceed in state courts unless the employee can show a plausible federal defense. State prosecutors retain primary responsibility for ordinary criminal enforcement, and federal officers cannot automatically shift local cases to federal court. The ruling helps avoid imposing added logistical burdens on state systems and preserves state control over ordinary crime enforcement.

Dissents or concurrances

Justice Brennan, joined by Justice Marshall, concurred in the judgment but stressed that in rare cases of local hostility aimed at federal functions, careful pleading might still permit removal even without a formal federal defense.
