MADISON, Wis. — Wisconsin Gov. Scott Walker's top aide says the administration will abide by a judge's order to stop preparation to implement a divisive collective bargaining law.

Department of Administration Secretary Mike Huebsch said Thursday that the Republican governor's administration still believes the law took effect when a state office posted online last week. But he says Walker will abide by Dane County Circuit Judge Maryann Sumi's ruling earlier Thursday that the law hadn't taken effect.

Sumi's ruling came after Walker's administration ignored a restraining order she issued earlier this week saying work on the law should stop while she considers a lawsuit challenging the statute's legitimacy.

Walker officials had contended the order didn't apply to them because they weren't named as defendants in the lawsuit.
