Windsor was the lead plaintiff in the 2013 US supreme court case that struck down the Defense of Marriage Act of 1996, giving gay and lesbian couples access to federal benefits and laying the foundation for the landmark decision to legalize same-sex marriage across the country in 2015.
Doma, as the law was known, prevented countless of same-sex couples across the country from claiming a huge array of federal benefits accessible to heterosexual spouses, and epitomized discrimination in the eyes of the gay rights community.
When Windsor’s lifelong partner died in 2009, the IRS billed her for more than $300,000 in estate taxes she would not have owed had the government recognized their marriage*2.
