Watson v. Employers Liability Assurance Corp., 348 U.S. 66 (1954), was a conflict of laws case decided by the Supreme Court of the United States.

[1] Plaintiff was injured in Louisiana by a home-perm product made by an Illinois company which was insured by the defendant Massachusetts company, the insurance policy having been negotiated and issued in Massachusetts.

The Plaintiff brought suit under a Louisiana law which lets tort victims sue the insurer directly.

However, the insurance contract has a clause recognized as binding in Massachusetts and Illinois that prohibits such direct suits.

Louisiana's interest in taking care of persons injured there (and probably paying medical bills there too) outweighs the interests of Massachusetts in the contract, so it is no violation of Fourteenth Amendment Due Process or Full Faith and Credit Clause to apply Louisiana law.
