TOPEKA, Kan. (AP) — The Kansas Supreme Court has ruled that a state law stripping public school teachers of guaranteed tenure does not violate the state or federal constitution.

The court issued a unanimous ruling Friday against two veteran teachers who sued their Butler County school district after it did not renew their contracts in 2015.

The Republican-controlled Legislature enacted the law ending guaranteed tenure in 2014 through a measure that also boosted spending on public schools.

Before the change, teachers with three or more years in the classroom had a right to have the non-renewal of their contracts reviewed by an independent hearing officer. Local school boards now set each district’s policy.

The Supreme Court rejected the teachers’ argument that tenure represented a property right that lawmakers could not modify or take away.
