Chicago Public Schools officials say they've filed lawsuits over the Illinois State Charter School Commission's decision to block plans closing three underperforming charter schools.
The lawsuits were filed on Wednesday in Cook County and claim the commission is overstepping charter school law.
Schools CEO Forrest Claypool says the commission has "ignored its own academic standards" to keep underperforming schools open.
He's also called on state legislators to cut the commission's power.
Earlier this month the commission overturned the district's closure plan. That changes how the schools are operated and funded by the state.
Critics have said the decision to close the schools came too fast in the wake of policy changes. Commission officials have said CPS didn't follow the charter agreement terms.
A commission spokeswoman declined to comment.
