MADISON, Wis. (AP) — Republicans who control the Wisconsin Legislature’s finance committee refused Tuesday to allow Democratic Attorney General Josh Kaul to settle an unknown lawsuit in a messy first test of their lame-duck laws limiting the attorney general’s powers.

Republicans passed provisions during a December lame-duck session that require Kaul to get the finance committee’s permission to settle lawsuits. The language is designed to ensure Kaul can’t weaken contentious Republican-authored statutes. Republican lawmakers filed a lawsuit earlier this month with the state Supreme Court alleging Kaul hasn’t been complying with the law.

Kaul sent committee members an email Friday afternoon saying he wanted to meet quickly about a case.

The GOP moved Tuesday’s meeting behind closed doors, citing a section of Wisconsin’s open meetings law that allows closed meetings to deliberate with attorneys about potential litigation. Committee clerk Joe Malkasian said he didn’t believe the committee had ever met in closed session before.

Republicans opened up the meeting after about 90 minutes but said they and Kaul were at a stalemate. They said they had no idea what the lawsuit is about because Kaul wouldn’t tell them unless they signed non-disclosure agreements.

“We don’t even know what the case is,” Rep. John Nygren of Marinette, the committee’s co-chairman, said.

Kaul warned there would be “significant harm to the state if we don’t move forward.” He didn’t elaborate but said he can’t move forward without a guarantee of confidentiality.

Committee Democrats hinted that the lawsuit is a multi-state action that Kaul’s predecessor Republican Brad Schimel joined, but they offered no further details. They complained that the permission-seeking process laid out in the lame-duck laws is unworkable and will result in more impasses given that many settlements require confidentiality.

“Today was a mess and it cannot be how the state resolves complex litigation going forward,” Rep. Evan Goyke of Milwaukee said.

Rep. Chris Taylor of Madison said she believes the closed session was illegal because the committee has no attorneys to consult. Nygren said Steve Fawcett from Assembly Speaker Robin Vos’ staff and Jessie Augustyn from Senate Majority Leader Scott Fitzgerald’s staff served as the panel’s lawyers.

The Wisconsin Bar Association website shows both are licensed to practice law in Wisconsin. Democratic Sen. Jon Erpenbach of Middleton complained that the committee never formally appointed them as its attorneys. He also predicted Republicans would be harshly criticized for the closed session.

“There was a day when we were better than this,” Erpenbach said. “People are going to find out about this and say ‘what the hell is going on there?’”

Nygren countered that attorney generals have been unilaterally settling lawsuits for as long as he could remember. He said involving the finance committee “helps the public understand it better, not worse.”

Kaul spokeswoman Gillian Drummond said the state Department of Justice has until Friday to agree to the settlement.

It was unclear where things stood as the meeting broke up. Nygren and other Republicans ignored reporters on their way out of the room. Sen. Luther Olsen was the only Republican who spoke to reporters, and he shrugged his shoulders and said he didn’t know what was going on.
