On Friday the Supreme Court announced that it will hear cases challenging the state and federal laws that define marriage as being between a man and a woman, New York Times Reports.
One court case is from California and challenges weather same-sex marriages should hold the same constitutional right as heterosexual marriages. The other, from New York, challenges a federal law that denies benefits to gay marriages.
Gay marriage is legal, or on its way to becoming legal in Connecticut, Iowa, Maine, Maryland, Massachusetts, New Hampshire, New York, Vermont, and Washington.
A total of 31 states, though, have amended their constitutions to prohibit gay marriage.
The Supreme Court will be heard around March, with the decisions expected by late June.
