A gay couple together 27 years has filed a lawsuit against the Texas county clerk who has refused to issue them a marriage license.

Jim Cato and Joe Stapleton have been together 27 years. The couple has been repeatedly refused a marriage license by Hood County Clerk Katie Lang.

In a written statement, Lang said that her religious faith compels her “to personally refrain from issuing same-sex marriage licenses” but that other staffers will issue marriage licenses to gay and lesbian couples in accordance with the recent Supreme Court ruling striking down state bans on gay marriage.

Lang's office, however, has yet to issue such a license, claiming that she has yet to receive the appropriate forms.

Lang has the backing of Texas Values. The conservative group held a rally in support of Lang last week. According to the group, more than 200 people attended Thursday's rally.

“We will not stand by and watch as LGBT radicals try to destroy the guarantees of the First Amendment of our Constitution and ruin the personal lives of Texans who support marriage between one man and one woman,” said Jonathan Saenz, the group's executive director. “We will not be silent.”

The lawyer representing Cato and Stapleton said that he provided Lang with copies of a revised marriage license application available on Texas' website, but was told a different form was still needed, according to the complaint filed Monday.

The couple “found the entire process to be humiliating and degrading, and have no reason to believe that hey would receive a marriage license without having to file a lawsuit to get it,” the suit says.
