The Delaware Supreme Court on Wednesday reversed the dismissal of a “take-home” asbestos case, ruling that the estate of a worker’s spouse who regularly washed her husband’s asbestos-contaminated clothing had a viable claim against two manufacturers that supplied the dangerous products to his employer.

The unanimous ruling from the state’s five justices overruled a strand of Delaware case law that shielded employers from liability to workers’ spouses, and in turn expanded exposure to liability for companies that make products used in industrial processes.
