LITTLE ROCK, Ark. (AP) - Same-sex couples challenging Arkansas' gay marriage ban are asking any state Supreme Court justices who plan on seeking re-election to recuse from the case, arguing a legislative resolution supporting the prohibition could sway their opinion.

The couples on Monday filed a motion asking any justice expecting to run for re-election anytime in the future to not hear the appeal of a state judge's decision striking down the state's ban on same-sex marriage. Pulaski County Judge Chris Piazza struck down the ban earlier this year, which led 541 gay couples receiving marriage licenses before Piazza's ruling was suspended by the state Supreme Court.

A legislative panel in June approved a resolution condemning Piazza's decision and urging justices to uphold the ban. The ban is also being challenged in federal court.
