Wisconsin Judge Ehlke: Questions Kaul Suit Over Claim Preclusion, Citing Prior Litigation

• A Dane County Circuit Court judge criticized Wisconsin Attorney General Josh Kaul's office for potentially duplicative lawsuits seeking more control over state-involved settlements.
• The current lawsuit, filed in April, challenges the Legislature's finance committee's veto power over certain settlements, arguing it violates separation of powers.
• This dispute is part of Attorney General Kaul's long-standing battle against 2018 'lame duck' laws that shifted his office's powers to the Republican-controlled Joint Committee on Finance.
• The Wisconsin Supreme Court previously ruled in Kaul's favor twice, affirming his final say on civil suits and allowing him to control settlement funds, but the finance committee retained its veto power.
• The recent court hearing focused on whether the current case is barred by claim preclusion, a legal doctrine preventing re-litigation of issues that could have been raised in prior lawsuits.

Judge Stephen Ehlke emphasized that preserving judicial resources and ensuring timely resolution of matters are core functions of the court, suggesting that issues capable of being decided should be.

A Wisconsin judge recently expressed significant reservations regarding a new lawsuit filed by Attorney General Josh Kaul, which seeks to further define his office's control over state-involved settlements. During a hearing in Dane County Circuit Court, Judge Stephen Ehlke openly questioned the Attorney General's office, suggesting that the ongoing litigation against the Legislature might be consuming judicial resources unnecessarily through what he termed 'piecemeal suits.' This latest legal action represents another front in Kaul's multi-year effort to reclaim powers that were curtailed by legislative changes enacted in 2018.

The current challenge, initiated in April, specifically targets the Republican-controlled Joint Committee on Finance's veto authority over certain civil suit resolutions. Attorney General Kaul's office contends that this veto power, as applied to two distinct categories of cases, constitutes a violation of the separation of powers. The recent court proceedings centered on whether this lawsuit is too similar to a previous case, referred to as Kaul I, which was decided by the Wisconsin Supreme Court in June 2025. A key point of contention during the hearing was why the arguments presented in the current case were not brought forward during that earlier Supreme Court challenge.

The central legal argument debated before Judge Ehlke revolved around the doctrine of claim preclusion. Representing the Legislature, attorney Misha Tseytlin of Troutman Pepper Locke argued that this legal principle should bar the current lawsuit. Tseytlin asserted that the Attorney General and the Governor had ample opportunity, and indeed a responsibility, to raise the theories now being presented, at the very latest when they filed their hybrid lawsuit in Kaul I. This position suggests that the issues at hand could and should have been litigated in the prior Supreme Court case.

Assistant Attorney General Hannah Jurss countered, arguing that claim preclusion should not apply in the same manner to disputes involving fundamental separation of powers issues. Jurss maintained that the current lawsuit and Kaul I address entirely different interests. She highlighted the Legislature's own argument that Kaul I is not controlling in this new context as evidence that the cases are distinct. However, Judge Ehlke appeared unconvinced by these arguments, going so far as to suggest that Jurss's interpretation could effectively undermine the very purpose of claim preclusion. The judge specifically questioned why the issue of the finance committee's veto power was not raised in Kaul I, particularly since the final approval of settlements was a central component of that earlier litigation.

Attorney General Josh Kaul has been engaged in a protracted legal struggle against a series of 'lame duck' laws enacted in 2018. These legislative changes were passed after Kaul's election but before he officially took office, and they significantly transferred many of the Attorney General's powers to the Joint Committee on Finance. A substantial portion of these laws specifically targeted civil suits involving the state, granting the committee final approval over settlements and control over the resulting funds. This arrangement persisted until recent rulings by the Wisconsin Supreme Court.

Kaul achieved two significant victories at the state's highest court. In June 2025, the Supreme Court restored the Attorney General's final authority over civil suits, determining that the 'lame duck' policy violated the constitutional separation of powers. The court unanimously found that the Legislature could not simultaneously define the scope of the Attorney General's litigation powers and then assume those executive powers itself. Following this decision, Kaul issued a statement expressing that the ruling would 'finally put an end' to the Legislature's involvement in certain civil suit resolutions. A subsequent ruling in July further sided with Kaul, allowing him to deposit uncommitted settlement funds into a general fund managed by his office. Despite these successes, the Joint Committee on Finance notably retained its veto power over state-involved settlements, setting the stage for the current legal challenge.

This ongoing legal battle underscores persistent ambiguities regarding the Wisconsin Attorney General's ultimate authority over state-involved settlements and highlights the complexities of separation of powers challenges within the state. Judge Ehlke's pointed questions about judicial resource allocation and the application of claim preclusion signal the court's concern over successive litigation of related issues. The judge explicitly stated that a core function of the court is to preserve its resources and ensure that matters are ruled upon when they are ripe for decision, even noting that claim preclusion does not require absolute identity between causes of action to apply.

While Judge Ehlke did not issue a final decision on the claim preclusion issue during the recent hearing, he did order limited and focused discovery specifically pertaining to the second category of cases outlined in Kaul's latest challenge. This directive indicates that the court intends to delve deeper into the specifics of the current claims before making a definitive ruling on whether the lawsuit can proceed. The outcome of this case will have significant implications for the balance of power between the executive and legislative branches in Wisconsin, particularly concerning the Attorney General's autonomy in resolving legal disputes involving the state.

This case underscores the ongoing legal uncertainty regarding the Wisconsin Attorney General's final authority over state-involved settlements and the application of claim preclusion in separation of powers challenges. Lawyers advising clients involved in litigation with the State of Wisconsin should monitor this dispute for clarity on settlement approval processes and potential precedents regarding successive challenges to legislative power.
