Overland Park ? Residents in a northeast Kansas school district have filed a federal lawsuit that challenges the constitutionality of the state’s formula for funding schools.

The lawsuit was filed Friday in federal court in Kansas City, Kan. It’s aimed at stopping the Shawnee Mission School District in Johnson County from closing three schools because of budget problems.

The state’s school funding law limits how much residents can raise their local taxes to supplement state funds for their schools.

The Kansas City Star reports that a vote is scheduled for Monday by the district on a proposal to close the three schools. The plaintiffs want the school board to reject the proposal or wait until the lawsuit is resolved.
