With a creative line-item change in the state budget, Wisconsin’s governor implemented a four-century increase in spending for its public schools.
State law allows Democrat Tony Evers to strike words and numbers from a proposed revenue increase through 2025, instead locking in funds until 2425.
Republicans reacted with outrage at what they called “an unprecedented new way to screw over the taxpayer”.
The move could be overturned by a legal challenge or a future governor.
It is the latest battle between Mr Evers, a former public school teacher who narrowly won re-election last year, and a Republican-controlled state legislature that has consistently blocked his agenda.
Their original budget proposal increased the amount that school districts can provide through property taxes, to $325 (£250) per student, for the next two school years.
But Wisconsin allows its governors to change certain pieces of legislation with words and numbers they see fit before they are signed into law – known as partial veto power.
Both Democrats and Republicans have changed their partial veto authority over the years, with Mr Evers’ Republican predecessor once deploying it to extend the state’s program deadline by a thousand years.
This week, before he signed the state’s biennial budget into law, the governor revised language that applied for an increase of $325 in the 2023-24-24 and 2024-25 school years, gi -vetoe a hyphen and a “20” to make the final date 2425.
He also used his power to scrap proposed tax cuts for the state’s wealthiest taxpayers and protect about 180 diversity, equity and inclusion jobs that Republicans want to cut at public universities. Wisconsin.
“There are a lot of wins here,” Mr Evers said at the budget signing ceremony on Wednesday.
In a statement, he said he “advanced through strategic vetoes” a bill that was “imperfect and incomplete”, declaring a “huge increase in categorical aid for our schools”.
State Republicans blasted the measure, warning it would result in massive property tax increases.
“Legislative Republicans have worked tirelessly over the past few months to block Governor Evers’ liberal tax and spending agenda,” Assembly Speaker Robin Vos said in a statement.
“Unfortunately, because of his strong veto authority, he’s taking some of it back now.”
Vetos cannot be overridden unless there is a two-thirds majority in the assembly in favor, which is unlikely as Democratic votes are needed.
But Rick Esenberg, director of the conservative Wisconsin Institute for Law and Liberty, told the Associated Press that he expected a legal challenge to the veto, calling it “a ridiculous way to legislate”.
