A ruling on whether Illinois’ pension overhaul law is constitutional could be delayed until next year.

A Sangamon County circuit judge wants to consider all of the issues raised in multiple lawsuits. Judge Jon Belz ruled  handling it differently could lead to piecemeal rulings and actually prolong a resolution.

Lawyers for state retiree groups wanted the judge to answer whether the law increasing contributions by workers and decreasing their benefits violates the state Constitution.

The schedule Belz laid out for arguments and responses in the lawsuits stretches the case into December.
