5 U.S.C. § 7202: Marital status

The President may prescribe rules which shall prohibit, as nearly as conditions of good administration warrant, discrimination because of marital status in an Executive agency or in the competitive service. Regulations prescribed under any provision of this title, or under any other provision of law, granting benefits to employees, shall provide the same benefits for a married female employee and her spouse and children as are provided for a married male employee and his spouse and children. Notwithstanding any other provision of law, any provision of law providing a benefit to a male Federal employee or to his spouse or family shall be deemed to provide the same benefit to a female Federal employee or to her spouse or family.
