If it wasn't clear last time, Dane County Circuit Judge Maryann Sumi made it clear on Tuesday: Any further implementation of Gov. Scott Walker's law limiting public employee unions is barred, and anyone who violates her order risks sanctions.

Sumi made her ruling at the end of a day of testimony in the open meetings lawsuit brought by Dane County District Attorney Ismael Ozanne. The hearing is scheduled to conclude on Friday.

"Now that I've made my earlier order as clear as it possibly can be, I must state that those who act in open and willful defiance of the court order place not only themselves at peril of sanctions, they also jeopardize the financial and the governmental stability of the state of Wisconsin," Sumi said.

Her statement appeared to be a warning to state agencies, such as the state Department of Administration, that have begin implementing the union bill despite a temporary restraining order that Sumi issued on March 18 and the unsettled question about whether publication of the law by the Legislative Reference Bureau on Friday was enough to implement the law.

"Apparently that language was either misunderstood or ignored, but what I said was, ‘the further implementation of 2011 Wisconsin Act 10 is enjoined,' " Sumi said. "That's what I now want to make crystal clear."
