Judge strikes down Walker's collective bargaining law Dane County judge struck down Gov. Scott Walker's controversial collective bargaining law on Thursday, ruling that a legislative committee violated the state's open meetings law when it hastily convened to amend the measure. The ruling by Dane County Circuit Judge Maryann Sumi won't end the legal fight over the law, which sharply curtails the collective bargaining rights of most public employees in Wisconsin. An appeal of Sumi's decision is all but certain. And the state Supreme Court is set to hear oral arguments on June 6 over whether to take the case immediately in response to an earlier request by the state Department of Justice and state Department of Administration challenging Sumi's authority to act in the case.
