The Supreme Court of the United States will hear arguments for two same-sex marriage cases on March 26 and 27.

On the 26th, arguments will be made in Hollingsworth v. Perry challenging California's Proposition 8. On the 27th, the court will hear arguments in United States v. Windsor, which challenges the constitutionality of Section 3 of the federal Defense of Marriage Act, which bars the federal government from recognizing such marriages for purpose of determining tax bills, health benefits or other rights and responsibilities straight couples take for granted.
