The plaintiffs in a school funding lawsuit have filed a motion to block the governor’s new school funding plan.

The motion was filed Thursday and calls on the court to bar the state from enacting the law overhauling the way the state distributes aid to schools. Kansas Gov. Sam Brownback signed the plan into law Wednesday. His office referred questions to the attorney general’s office, which didn’t immediately return phone or email messages from The Associated Press.

The three-judge panel assigned to case has ruled that it may take measures to preserve the status quo and will hear argument for blocking the law May 7.

The law scraps the state’s school funding formula and gives each district a fixed amount of money for the next two years.
