Governor Pat Quinn is still being blocked from proceeding with his plans to close two state prisons and other Corrections facilities.
An appeals court panel has rejected a request from the governor to overturn a lower court ruling that puts the closures on hold.
That means a 30-day temporary restraining order that was issued earlier this month will remain in effect.
The order prevents any further moves on the closure until early next month, while talks continue with AFSCME on how to implement the moves without jeopardizing the safety of prison inmates and staff.
