In a rebuff to state officials, the head of the federal Elections Assistance Commission has rejected Arizona's request to require proof of citizenship by those using a federal form to register to vote.

The executive director of a federal commission with no commissioners is going to decide whether Arizona can require voter registrants who use federal forms to provide proof of citizenship.

Arizona’s new policy of having separate voter rolls for people who didn’t provide proof of citizenship when registering is likely to stir up a lawsuit before the 2014 elections.

Following the guidance of a U.S. Supreme Court justice, Attorney General Tom Horne has threatened to sue an effectively non-existent federal commission if it doesn’t put Arizona’s requirement of proof-of-citizenship on federal voter registration forms.

Horne is giving the U.S. Election Assistance Commission until Aug. 19 to act, stating in a July 26 letter to the commission’s acting executive director, Alice Miller, that Louisiana recently got approval to put requirements specific to the state on the federal forms.

Arizona has taken the U.S. Supreme Court’s advice to sidestep its ruling against the state, but there’s a catch. In doing so, it would be appealing to an effectively non-existent federal commission.

Supreme Court justices disagreed Monday over whether states can require would-be voters to prove they are U.S. citizens before using a federal registration system designed to make signing up easier.

Supporters of Arizona's SB1070 commended the U.S. Supreme Court today for upholding a key provision in the immigration law that they say is its most important section.
