MADISON, Wis. (AP) — Justices on the Wisconsin Supreme Court said Wednesday that Gov. Tony Evers' creative use of his expansive veto power in an attempt to lock in a school funding increase for 400 years appeared to be “extreme” and “crazy" but questioned whether and how it should be reined in.

“It does feel like the sky is the limit, the stratosphere is the limit,” Justice Jill Karofsky said during oral arguments, referring to the governor's veto powers. “Perhaps today we are at the fork in the road ... I think we’re trying to think should we, today in 2024, start to look at this differently.”

The case, supported by the Republican-controlled Legislature, is the latest flashpoint in a decades-long fight over just how broad Wisconsin's governor's partial veto powers should be. The issue has crossed party lines, with Republicans and Democrats pushing for more limitations on the governor's veto over the years.

In this case, Evers made the veto in question in 2023. His partial veto increased how much revenue K-12 public schools can raise per student by $325 a year until 2425. Evers took language that originally applied the $325 increase for the 2023-24 and 2024-25 school years and instead vetoed the “20” and the hyphen to make the end date 2425, more than four centuries from now.

“The veto here approaches the absurd and exceeds any reasonable understanding of legislative or voter intent in adopting the partial veto or subsequent limits,” attorneys for legal scholar Richard Briffault, of Columbia Law School, said in a filing with the court ahead of arguments.

That argument was cited throughout the oral arguments by justices and Scott Rosenow, attorney for Wisconsin Manufacturers & Commerce Litigation Center, which handles lawsuits for the state's largest business lobbying group and brought the case.

The court should strike down Evers’ partial veto and declare that the state constitution forbids the governor from striking digits to create a new year or to remove language to create a longer duration than the one approved by the Legislature, Rosenow argued.

Finding otherwise would give governors unlimited power to alter numbers in a budget bill, Rosenow argued.

Justices appeared to agree that limits were needed, but they grappled with where to draw the line.

When legal scholars and others look at what Wisconsin courts have allowed relative to partial vetoes, “they think it’s crazy because it is crazy,” said Justice Brian Hagedorn. “We allow governors to unilaterally create law that has not been proposed to them at all. It is a mess of this court’s making.”

The initial reaction from anyone would be that a 400-year veto is “extreme,” said Justice Rebecca Dallet, but the question is whether it's within the governor's authority to use the partial veto to extend the duration of dates.

“The governor is becoming the most powerful person in the state, arguably, to just make the law whatever he declares,” said Justice Rebecca Bradley.

Evers, his attorney Colin Roth argued Wednesday, was simply using a longstanding partial veto process that is allowed under the law.

The court, controlled 4-3 by liberals, will issue a written ruling in the coming months.

Wisconsin’s partial veto power was created by a 1930 constitutional amendment, but it’s been weakened over the years, including in reaction to vetoes made by former governors, both Republicans and Democrats.

Voters adopted constitutional amendments in 1990 and 2008 that removed the ability to strike individual letters to make new words — the “Vanna White” veto — and the power to eliminate words and numbers in two or more sentences to create a new sentence — the “Frankenstein” veto.

The lawsuit before the court on Wednesday contends that Evers’ partial veto is barred under the 1990 constitutional amendment prohibiting the “Vanna White” veto, named the co-host of the game show Wheel of Fortune who flips letters to reveal word phrases.

But Evers argued that the “Vanna White” veto ban applies only to striking individual letters to create new words, not vetoing digits to create new numbers.

Reshaping state budgets through the partial veto is a longstanding act of gamesmanship in Wisconsin between the governor and Legislature, as lawmakers try to craft bills in a way that is largely immune from creative vetoes.

The Wisconsin Supreme Court, then controlled by conservatives, undid three of Evers’ partial vetoes in 2020, but a majority of justices did not issue clear guidance on what was allowed. Two justices did say that partial vetoes can’t be used to create new policies.
