Decision: Pacific Employers Ins. Co. v. Industrial Accident Comm’n, 306 U.S. 493 (1939).

Pacific Employers Insurance Co. v. Industrial Accident Commission involved a Massachusetts resident regularly employed under a written contract in Massachusetts, temporarily sent to California and injured there. He received California compensation despite the Massachusetts statute’s exclusivity language.

California was the place of injury

The employment relationship originated elsewhere, but the work accident occurred within California while the employee performed an assignment there.

Both states had compensation interests

Massachusetts sought to make its remedy exclusive; California sought to protect workers injured within its borders and regulate local injury consequences.

Full Faith and Credit allowed California’s policy choice

The Constitution did not require California to substitute Massachusetts policy for its own in a matter where California was competent to legislate.

The earlier interstate compensation decision did not control

The Court distinguished Bradford Electric Light Co. v. Clapper, 286 U.S. 145. In that earlier case, applying Vermont’s law had not been shown to offend New Hampshire’s policy. The California record was different: California had expressed a policy of applying its own compensation law to injuries within the state. See Pacific Employers, pages 503–505.

Key takeaways

• Inventory every state contact before selecting governing law.
• Compare exclusivity, coverage, credit, and extraterritorial provisions.
• Explain the forum state’s legitimate interest in the injury.
• Check current statutes and reciprocal-credit rules before filing.
