Colorado Attorney General John Suthers on Thursday sued Boulder County Clerk Hillary Hall for refusing to stop issuing marriage licenses to gay and lesbian couples.

Hall began issuing the licenses last week after the Tenth Circuit Court of Appeals in Denver upheld a lower court's ruling striking down Utah's constitutional amendment limiting marriage to heterosexual unions.

The appeals court's jurisdiction includes Colorado, but the decision was stayed by the court. Hall said the court's stay only applied to Utah.

According to the AP, the county has issued roughly 100 licenses to gay couples as of Thursday.

“While we would prefer not to sue a government official, Ms. Hall's actions are creating a legal limbo for both the state and the couples whose relationships she wants to champion,” Suthers said in a statement. “That limbo could have tangible and unintended consequences.”

A hearing is set for Wednesday.

Meanwhile, the state has sided with six plaintiff couples challenging the state's ban in federal court. Suthers, a Republican, and Democratic Governor John Hickenlooper asked the court to declare the ban invalid but delay implementation until the Supreme Court has ruled in the Utah case.
