MADISON, Wis. (AP) -- Wisconsin Supreme Court Justice Michael Gableman says he won't step aside in an attempt to reopen last year's decision that allowed Gov. Scott Walker's contentious collective bargaining law to take effect.

Gableman said Friday he won't recuse himself in three cases.

Attorneys in the cases had asked Gableman to remove himself because other parties in the cases were represented by a law firm that defended Gableman against an ethics allegation without billing him.

One of the other cases involves the siting of a large heifer facility in Rock County. The other is over whether to use old or new legislative maps for likely recall elections of state senators.

The Milwaukee Journal Sentinel reports the full court will now have to decide whether to force Gableman from the cases.
