BOISE, Idaho (AP) — A former Idaho school district superintendent has filed a lawsuit against the state arguing public schools are violating the state constitution by charging students fees for what is supposed to be a free education. The Spokesman-Review ( ) reports former Nampa superintendent Russell Joki is spearheading a class action lawsuit seeking the refund of nearly $2.4 million in fees families paid for registration and school supplies he argues the schools should be providing. The lawsuit, filed Monday in 4th District Court in Ada County, names the state, Superintendent of Public Instruction Tom Luna, the Department of Education, the state Legislature and school districts statewide. Bob Cooper, spokesman for the Idaho attorney general's office, declined comment because they had not seen the lawsuit.
