TOPEKA, Kan. (AP) — Kansas Democratic lawmakers say they’ve been circulating a petition to force a special legislative session to address the school funding.

The move comes after the Kansas Supreme Court rejected the Legislature’s latest attempt to enact a constitutionally equitable school funding system. The high court has meanwhile kept a June 30 deadline for lawmakers, raising the possibility that schools could close if the date passes without further legislative action.

The Topeka Capital-Journal reports that House Minority Leader Tom Burroughs and Senate Minority Leader Anthony Hensley said in a letter sent Saturday evening to Gov. Sam Brownback that they’ve begun collecting signatures to force the governor to call a special session to find a solution to “equitably fund Kansas schools.”

Brownback’s office hasn’t given any indication of its plans.
