CHICAGO (AP) — Supporters are continuing a fight to put legislative term limits on the November ballot, telling an Illinois appeals court that voters deserve a chance to weigh in on the measure.

The Committee for Legislative Reform and Term Limits gathered about 600,000 signatures for an initiative that would limit legislators to eight years in office, among other changes. The group is led by Republican gubernatorial candidate Bruce Rauner.

However, a Cook County judge ruled the effort unconstitutional after a lawsuit was filed.

The two sides argued Thursday before the Chicago-based 1st District Appellate Court.

If the appellate court doesn’t reverse the Cook County judge’s ruling, the committee plans to appeal to the Illinois Supreme Court.

The high court declined earlier this year to immediately consider the lower court’s ruling.
