In the first reported ERISA decision post-Windsor, the U.S District Court for the Eastern District of Pennsylvania held (in Cozen O’Connor, P.C. v. Jennifer Tobits) that a same-sex spouse is to be treated as the decedent’s lawful spouse for purposes of entitlement to death benefits under a retirement plan. In reaching its decision, the court relied on Windsor and reasoned that ERISA and the Internal Revenue Code (Code) provide the definition of spouse; ERISA and the Code incorporate valid state law; and, under Illinois’ civil union statute, Illinois recognizes lawful same sex marriages solemnized in other jurisdictions.
