From Law.com:
In a decision that could having a chilling  effect on nonprofit hospitals, the Illinois Supreme Court on Thursday  ruled that a Catholic hospital wasn't charitable enough, so it took  away the hospital's tax-exempt status.
The ruling upheld a state tax review  board's 2003 decision to end Provena Covenant Medical Center's tax-exempt  status after the state learned that the center's charity care equaled  less than 1 percent of revenue. Now, the hospital is liable for a multimillion-dollar  property tax bill.
The Illinois decision comes as lawmakers  in that state and in the nation's capital, as well as the Internal Revenue  Service, are watching hospitals more closely with regard to their charitable  giving. The IRS is scrutinizing hospitals' year-end tax filings, while  lawmakers are talking about legislation to mandate a certain minimum  level of charity care to justify tax-exempt status.
 
The Illinois ruling could bolster those  efforts. "My biggest concern is that this will really drive more  challenges to property tax exemption status for hospitals and other  charities nationally at a time when they really can't afford it,"  said Elizabeth Mills, senior counsel to the Chicago office of Proskauer  Rose.
Mills questioned the court's finding  that the hospital wasn't charitable enough, noting that Illinois law  sets no particular level of charity care linked to tax-exempt status.
