TOPEKA, Kan. (AP) — The Kansas Supreme Court will not allow the Shawnee Mission School District to intervene in a lawsuit over school funding.

The court on Monday upheld a lower court’s ruling that Shawnee Mission, a wealthy district in Johnson County, waited too long to intervene in a lawsuit brought by four other school districts in 2010.

Wichita, Hutchinson, Kansas City and Dodge City districts contend in the lawsuit that current school funding in Kansas does not meet a state mandate to provide suitable school funding.

Shawnee Mission argued that the four districts and the state could not adequately represent its interests.

The Wichita Eagle reports (http://bit.ly/1OrU7qd ) the court agreed that Shawnee Mission’s interests aren’t adequately represented said the district should have sought to intervene earlier.
