"[This case] highlights the reality and potential impacts of a retroactive application of Windsor. Plan administrators and fiduciaries should remain aware of the possibility of claims brought under Title I of ERISA to enforce a benefits claim by a participant in a same-sex marriage who retired before the Windsor decision ... Furthermore, Plan administrators should be aware that plan amendments that provide for recognition of same-sex marriages beginning on the date of the Windsor decision will not protect the plan and fiduciaries from Title I claims stemming from events prior to the Windsor decision." [Schuett v. FedEx Corp., No. 15-cv-0189 (N.D. Cal. Jan. 4, 2016)]
