Via the Salt Lake Tribune:
The ACLU of Utah is set Tuesday to announce a lawsuit against the state over the decision not to recognize marriages of same-sex couples performed before a stay was issued in the Amendment 3 case. The civil liberties organization started looking for plaintiffs on Jan. 8, the same day Gov. Gary Herbert’s office issued a directive putting state recognition of gay and lesbian newlyweds “on hold,” based on counsel from Attorney General Sean Reyes. The U.S. Supreme Court had issued a stay two days earlier of U.S. District Judge Robert Shelby’s Dec. 20 ruling that struck down Utah’s voter-approved constitutional amendment defining marriage as between one man and one woman.
