The 13 states that still ban same-sex marriage

In some cases, such as in Illinois, Hawaii, Minnesota and New York, lawmakers opened the doors voluntarily. In othersmost recently Alabamait’s been state or federal judges forcing the toehold long sought by gay rights advocates and bitterly contested by those who argue marriage is an institution reserved solely for one man and one woman.

As the dominoes fall in favor of same-sex marriages, the question now seems to be which state will be the last to allow such unions? That’s assuming, of course, that the U.S. Supreme Court doesn’t get there first by this June, when it is expected to issue its ruling on such bans in four states this spring.

Here’s the situation in the 13 states that currently ban same-sex marriages, including eight in which court rulings in favor of allowing same-sex marriage are under review:

Arkansas

The state’s constitutional ban on gay marriage, passed in 2004, was struck down twice last year — once by a state court judge and again by a U.S. District Court judge. Local officials issued some 400 marriage licenses following the state court decision, but the state Supreme Court blocked the issuance of more licenses pending its review of the case. A decision could come soon.

Ohio

A federal appeals court judge upheld a ban last year on same-sex marriages in the state. That decision is part of the U.S. Supreme Court case expected to be finalized this summer.

Tennessee

In November 2014, the U.S. Court of Appeals for the Sixth Circuit upheld the state’s ban. That decision also will be part of the U.S. Supreme Court case.
