Law Forward, a Madison-based liberal law firm, is suing the Republican-controlled Legislature over its use of taxpayer money to hire private attorneys.

The lawsuit, which was filed last month, comes after a 2025 Milwaukee Journal Sentinel investigation found the state Legislature had spent about $26 million in taxpayer money on legal fees to private law firms since 2017.

The investigation found the vast majority of the spending came after Democratic Gov. Tony Evers and Attorney General Josh Kaul won the November 2018 election, defeating Republican former Gov. Scott Walker and Attorney General Brad Schimel.

The sharp increase in spending also followed a law passed by Republican legislators in the December 2018 lame-duck session that authorized the Assembly speaker and Senate majority leader to hire private lawyers with taxpayer money.

“Wisconsin taxpayers deserve to know their money is being spent lawfully to advance a valid public purpose,” Law Forward President and General Counsel Jeff Mandell said in a statement. “This lawsuit challenges the tens of millions in taxpayer funds, most of which is wasted by the Republican-controlled Legislature on private legal counsel in pursuit of private interests.”

He called the practice a “clear violation of the Wisconsin Constitution’s public purpose doctrine and Wisconsin’s system of divided government.”

The lawsuit names as defendants the Assembly, Senate, Department of Administration and legislative leaders, including Assembly Speaker Robin Vos and Senate Majority Leader Devin LeMahieu.

Vos and LeMahieu could not be reached immediately for comment about the lawsuit.

The lawsuit cited a 2023 dispute in which the Senate continued to pay private counsel after it had been removed as a party in a case involving the use of surveillance cameras in Green Bay City Hall. The case cost the Senate more than $1 million in fees, according to records reviewed by the Journal Sentinel.

Assembly leaders also spent $1.8 million on fees related to former Wisconsin Supreme Court Justice Michael Gableman’s 2020 election probe, which found no evidence of fraud. The probe ended when Vos fired Gableman in August 2022. The legal fees did not include other investigation-related expenses, like Gableman’s salary. 

Much of the spending at issue stems from the 2018 lame-duck session, in which Republicans passed a series of laws stripping Evers and Kaul of various powers a month before they took office. One of those laws allowed legislative leaders to pay for outside counsel with taxpayer money and circumvent the attorney general to intervene in lawsuits that challenge state law.

Since then, the Legislature has spent more than $8 million defending challenges to the lame-duck laws.

In a July 2025 interview, Vos told the Journal Sentinel the laws ensured the governor did not consolidate too much power.

“The norm is for one person to try to take more authority, because they can make an easier, quicker decision,” Vos said.

“I think that’s really unhealthy for democracy, which is why we have so rigorously defended the right of the Legislature and the court to maintain its own independence,” he added.
