The attorneys for the state workers and retirees who are challenging the pension reform plan want more time from the Illinois Supreme Court to file their arguments. They say they need until March 16 to prepare their response to the state's claim that the reform is constitutional under the legislature's "police powers" that apply in an emergency. The reform law passed in 2013 changes the benefit structure and raises the retirement age as a way to fill a gaping 111-billion-dollar hole in the pension fund.
