Everything you need to know about Edie Windsor, the Supreme Court plaintiff who helped fight the Defense of Marriage Act. Edie Windsor helped bring down section 3 of DOMA. After the death of her late wife, Thea Spyer, Windsor was faced with the unfairness of a bill for $360,000 in estate taxes. That injustice won't happen to others because Windsor brought the case United States v. Windsor to the U.S. Supreme Court, which ruled that the section was unconstutional. Her cause was represented by Roberta Kaplan, a lesbian lawyer from the firm Paul, Weiss, Rifkind, Wharton & Garrison LLP.
