A conservative Florida group has sued to stop Orlando officials from issuing marriage licenses to gay and lesbian couples next week.

According to the AP, Florida Family Action on Tuesday filed two lawsuits.

A federal judge's order striking down Florida's gay marriage ban takes effect at the end of the day on Monday. But Florida officials argue that the ruling only applies to one county.

Lawyers for the plaintiffs disagree, saying that the state's 67 county clerks must begin issuing marriage licenses to gay couples who ask for them on Tuesday.

Orlando officials have pledged to issue marriage licenses to same-sex couples.

Officials named in the lawsuits include Osceola County Clerk of Court Armando Ramirez, Orlando Mayor Buddy Dyer and Circuit Judge Robert LeBlanc.

Florida Family Action also argues that the ruling only applies to one county.

The group's president, John Stemberger, strongly lobbied for passage of Florida's ban. In a recent Facebook post, he claimed that allowing gay couples to marry would harm children and vowed to “never give up on this issue” even “if it takes 20, 30, or 50 years.”
