UNDATED (CBS) -- This time tomorrow the issue of same sex marriage will be in front the nation's highest court. This week justices will hear arguments on two cases that could define marriage for the nation.
Kris Perry and Sandra Stier are in Washington fighting for their right to marry. The California couple visited the national archives to view the constitution on the eve of the Supreme Court hearing their case.
They're challenging California's proposition eight. In 2008 voters there approved a ballot measure banning same-sex marriage. Evan Wolfson with Freedom to Marry says, "The freedom to marry is one of the precious freedoms that all of us cherish and gay people like non-gay people deserve under the constitution the ability to shape a family to build a life and to have these dreams."
Supporters of the ban say it is a state issue. Austin Nimocks with the Alliance Defendign freedom says, "The last thing we need is to shut down the debate, have the Supreme Court redefine marriage for everybody, instead of letting us work through this question through our democratic institutions."
Wednesday's the justices hear a second case focusing on the 1996 Defense of Marriage Act. It defines marriage as between a man and a woman. Opponents say it discriminates against same-sex couples who are legally married because it denies them federal benefits.
People started lining-up Friday for a chance to see the arguments before the court. Even in the snow, they've hung onto their spots to get a seat inside Tuesday or Wednesday.
Same-sex marriage supporters have been rallying across the country and they'll be at the court tomorrow. Only nine States and the District of Columbia allow same-sex marriages. But, the court's ruling could impact the whole country.
The justices are not expected to issue their decisions until late June.
