Arkansas officials asked the state's highest court on Monday to allow them to enforce a voter ID law in the May 22 primary despite a judge blocking the measure and calling it unconstitutional.

Secretary of State Mark Martin asked the Arkansas Supreme Court to put on hold a Pulaski County judge's ruling preventing the state from enforcing the 2017 law requiring voters to show photo identification before casting a ballot. Martin asked the high court for a ruling by noon Friday, noting that early voting for the primary begins May 7.

"Here, the trial court has changed the rules in the middle of the election," Martin's filing said. "An immediate stay is necessary; any further delay will harm the state."

Pulaski County Circuit Judge Alice Gray sided with a Little Rock voter who sued the state and had argued the law enacted last year circumvents a 2014 Arkansas Supreme Court ruling that struck down a previous voter ID measure.

An attorney for the Little Rock voter said he hoped the court would not halt the ruling, noting evidence that nearly 1,000 votes weren't counted in the 2014 primary because of the previous voter ID law that was struck down later that year.
