Ohio is among four states whose ban on same-sex marriage was argued before the U.S. Supreme Court today.
Marc Spindleman, a constitutional law expert at the Moritz College of Law at Ohio State, says the justices must decide two pivotal questions brought forth in the challenge to the states' same-sex-marriage ban.
Spindleman says the Supreme Court must decide if states must grants same-sex marriage licenses that are on equal terms with traditional marriage license.
Another issue that needs to be addressed according to Spindleman is whether states must recognize valid marriage license that same sex couple get from other states or countries.
Spindleman examines arguments from both sides in this case as well as the potential outcomes based on the court's ruling which will be announced in June.
