A Sangamon County judge says he’ll issue a ruling tomorrow (Friday) on the constitutionality of Illinois’ pension overhaul — he’ll either issue a decision, or allow the proceedings to continue.

Attorneys wrapped up oral arguments today (Thursday) over whether the Illinois Constitution bars lawmakers from cutting their pension benefits. Anders Lindall of We Are One Illinois says it’s simple — don’t break promises.

“Our unions have long argued that the state cannot simply choose to violate the constitution and diminish or impair retirement benefits if politicians find these commitments inconvenient to keep,” says Lindall.

The law reduces benefits for retirees, but also reduces employee contributions. The lawsuit alleges the Constitution prohibits reducing any benefits or compensation once they’re promised. But the state says pension benefits can be reduced.
