Illinois' law cutting government pensions isn't scheduled to take effect until summer. But employees are already suing, arguing their pensions are protected by the Illinois Constitution, which says benefits "shall not be diminished or impaired."
That very phrase is also in the Arizona Constitution, and was the basis of the Arizona Supreme Court's unanimous decision striking down a law that sought to reduce benefits there. So: will this have an effect in Illinois?
Ann Lousin is a law professor and was on staff when the Illinois Constitution was drafted in 1970. She cautions that an Arizona case is not binding in Illinois. But ...
"On the other hand, all of these state constitutional provisions ... are substantively identical to each other."Because of that, Lousin says it's safe to say one state's decision on pensions would at least have a persuasive effect on cases in other states.
"In other words, the Illinois Supreme Court would look at what the Arizona Supreme Court has said today."
Illinois' pension cases are still in the early stages of the legal process.
