WASHINGTON -- The Supreme Court will issue its decision this month in Obergefell v. Hodges, the case that could affirm that same-sex couples around the country have the constitutional right to marry. Same-sex marriage is already legal in 37 states and the District of Columbia. But in the remaining states, gay couples are prohibited from marrying, and couples who were legally married in other states are barred from having their unions recognized in these non-marriage equality states.
