Illinois Attorney General Lisa Madigan's office is asking a state appellate court to hold back enforcement of its ruling on a part of a state law that lets hospitals avoid taxes. The appellate court ruled last month that the state's 2012 charity care law was unconstitutional because it created a tax exemption for hospitals without requiring the properties to be used only for charity purposes. Based on the appellate court's decision, the Champaign County Board of Review voted last week to place the Carle health system and Presence Covenant Medical Center back on the local tax rolls. A motion to stay the enforcement of the ruling says the Department of Revenue is seeking further appellate review in the state Supreme Court.
