The Supreme Court ruled that Section 3 of the Defense of Marriage Act (DOMA) was unconstitutional. This ruling impacts over 1,000 federal laws related to benefits like health insurance, taxes, and retirement plans by requiring the federal government to recognize same-sex marriages. However, many questions remain about how this will affect employer-sponsored health plans. Employers should wait for further guidance from federal agencies on key issues like which same-sex marriages are recognized before making changes to their plans to ensure compliance.
