The Supreme Court on Monday announced the dates they will hear two cases related to gay marriage which they agreed to hear last month.

Hollingsworth v. Perry, the legal challenge to Proposition 8, the 2008 voter-approved constitutional amendment which put an end to the weddings of gay and lesbian couples taking place in California after the state Supreme Court legalized such unions, will be heard on March 26. Defenders of Prop 8 appealed February's U.S. Ninth Circuit Court of Appeals ruling declaring that the marriage ban violated the Constitution's guarantee of equal protection.

The second case, United States v. Windsor, will be heard on the following day, March 27.

The case involves Edith Windsor, an 83-year-old lesbian widow who had to pay more than $360,000 in estate taxes after the death of her wife, Thea Spyer, because the government would not recognize their 2007 marriage due to the Defense of Marriage Act (DOMA). The women shared their lives together for 44 years.

The Court of Appeals for the Second Circuit agreed with Windsor's assertion that DOMA is unconstitutional. The 2-1 ruling was also the first to apply heightened scrutiny to the unions of gay couples.

The court is expected to rule on the two cases in June.
