BOULDER, Colo. -

A showdown over gay marriage licenses in Colorado could be resolved Wednesday.

Republican Attorney General John Suthers is suing the Boulder County clerk for ignoring a federal court stay on a recent gay marriage ruling and issuing same-sex marriage licenses. Suthers say the licenses are invalid because marriage must be between a man and a woman.

Boulder County Clerk and Recorder Hillary Hall says she is justified by a ruling last month by the 10th U.S. Circuit Court of Appeals that Utah isn't permitted to ban marriage based on gender. The court stayed its own ruling pending an appeal.

Hall has ignored the stay and issued more than 100 same-sex licenses. Suthers says her actions have created "legal chaos."

Boulder County District Judge Andrew Hartman is hearing Suthers' lawsuit Wednesday morning.
