A group defending a ballot item that would ban gay marriage want two state Supreme Court justices to step down from hearing a challenge to the proposal. The Arkansas Marriage Amendment Committee wants Governor Huckabee to appoint two replacement justices for the case. Huckabee supports a ban on gay marriage. The group filed motions Tuesday asking Justices Robert L. Brown and Annabelle Clinton Imber to recuse themselves from hearing a lawsuit seeking to prohibit the recognition of legal unions among homosexuals. The motions said Brown should step aside because he wrote an article praising a 2002 court opinion that decriminalized sodomy. They said Brown was supporting a purely policy-driven decision in support of gay rights. The motions also asked Imber to recuse herself because she once worked at the same law firm as a heterosexual man who has joined the plaintiffs in the lawsuit against the ballot initiative. Imber pointed out the connection on her own and said there was no conflict in it.
