DOMA unconstitutional: Defense of Marriage Act struck down
Roberts, Scalia and Alito all filed dissenting opinions. Thomas also dissented, but did not write an opinion.
The court says, "The federal government cannot disparage marriages recognized by the states," which means that legally married gay men and women are entitled to claim the same federal benefits that are available to opposite-sex married couples, such as joint tax filing or Social Security benefits.
Kennedy writes for the majority, "DOMA is unconstitutional as a deprivation of the equal liberty of persons that is protected by the Fifth Amendment."
President Obama tweets of the DOMA decision, "Today's DOMA ruling is a historic step forward for #MarriageEquality. #LoveIsLove."
SCOTUS also chose not to rule on the merits of Prop 8, which means the appellate judge's 2010 ruling that it is unconstitutional stands.
