Plaintiff of the US v. Windsor case challenging the constitutionality of Section 3 of the Defense of Marriage Act (DOMA), 83-year-old lesbian widow Edie Windsor (C), greets same-sex marriage supporters as she leaves the Supreme Court on March 27, 2013 in Washington, DC. The US Supreme Court tackled same-sex unions for a second day Wednesday, hearing arguments for and against the 1996 US law defining marriage as between one man and one woman. After the nine justices mulled arguments on a California law outlawing gay marriage on Tuesday, they took up a challenge to the constitutionality of the federal Defense of Marriage Act (DOMA). The 1996 law prevents couples who have tied the knot in nine states — where same-sex marriage is legal — from enjoying the same federal rights as heterosexual couples. (AFP PHOTO/Jewel Samad)
