This week, the Supreme Court will begin a hearing that could decide the future of same-sex marriage.
At issue in the case is a lower court decision upholding same-sex marriage bans in Michigan, Ohio, Tennessee, and Kentucky.
Two years ago, the Supreme Court ruled same-sex couples already legally married had the right to receive federal benefits.
But it dodged the central questions justices will face head-on Monday.
Those pushing for legalization of same-sex marriage nationwide say state bans violate equal protection under the law.
James Esseks of the American Civil Liberties Union says, “This is a case about couples who have been together for years and all they want is to express their love and commitment to each other in front of friends and family. That’s a basic American commitment, a basic American concept, and there is no reason that they should be treated differently than other people.”
Former Michigan Solicitor General John Bursch says, “Is it the people through the democratic process where this issue has always been decided, or is it the courts? And it’s the position of the states that the people get to decide”
Same-sex marriage is now allowed in 37 states and Washington D.C.
Recent polls on the issue also show growing support.
Five years ago, 49% of Americans saw same-sex marriage as being a constitutionally protected right.
Now that number has jumped to an all-time high of 63%.
