Four gay and lesbian couples on Friday filed a legal challenge to Indiana's ban on gay marriage.

According to the AP, the suit was filed in federal court in New Albany. It asks a judge to force Indiana to recognize the out-of-state marriages of gay couples and issue marriage licenses to same-sex couples.

The case comes just weeks after Indiana lawmakers altered the language of a proposed constitutional amendment seeking to limit marriage to a heterosexual union, keeping the amendment from reaching voters this November.

“I think it's fairly clear the people of Indiana cannot depend upon the legislature and the governor to do what is right, so we're turning to the federal courts to do it,” Dan Canon, one of several attorneys working on the case, told reporters.

Indiana Attorney General Greg Zoeller announced that his office will defend the law in court.

“People of goodwill have sincere differences of opinion on the marriage definition, but I hope Hoosiers can remain civil to each other as this legal question is litigated in the federal court,” Zoeller said in a statement.
