In a case that began with a claim for a refund of estate taxes paid, Judge Barbara S. Jones of the Southern District of New York ruled that the Defense of Marriage Act (DOMA) is unconstitutional under the Equal Protection Clause of the 5th Amendment.
Edie Windsor and Thea Spyer were a couple for over 40 years and in 2007 were married in Canada where same-sex marriage was legal. Their marriage was later recognized in their home state of New York. Upon Thea's death, Edie paid $363,053 in federal estate taxes because she was not eligible for the unlimited marital deduction under IRC Section 2056(a) - a benefit routinely applied to married couples of different sexes. Edie filed a claim for refund of the estate taxes on the grounds that DOMA denied her equal protection under the law as protected by the 5th Amendment to United States Constitution.
