Indiana is asking the U.S. Supreme Court to decide whether gay marriage should be legal in all 50 states.
The state attorney general's office on Tuesday asked the high court to reverse a ruling last week by the 7th Circuit U.S. Court of Appeals, which declared Indiana and Wisconsin's bans against same-sex marriage unconstitutional.
Indiana says its case offers a perfect opportunity to settle the national debate once and for all.
Attorneys for gay rights group Lambda Legal and the American Civil Liberties Union of Indiana say they will file separate responses within 24 hours.
The U.S. 7th Circuit Court of Appeals last Thursday upheld a federal district judge's decision that found Indiana's same-sex marriage ban violated the constitution.
