A Cook County judge on Friday ruled that signature-driven ballot measures calling for legislative term limits and a new political redistricting process can't appear on the November ballot.
Cook County Circuit Court Judge Mary Mikva said the measures don't meet constitutional requirements to make the ballot.
The ruling is a setback for groups advocating the measures, including one led by Republican governor candidate Bruce Rauner. He's made term limits a cornerstone of his campaign to unseat Democratic Gov. Pat Quinn.
Rauner's petition to add that question to the Nov. 4 ballot has garnered 333,164 legit signatures from registered voters, surpassing the requirement of $300,000 signatures, according to estimates by employees of the State Board of Elections.
An April poll of Illinois voters found that most were in favor of term limits for lawmakers in Springfield.
A lawsuit challenging the measures was filed by an attorney who represents top Democratic lawmakers.
Attorneys for the term limits advocates say they will appeal directly to the Illinois Supreme Court next week.
Another group wanted an independent commission to oversee Illinois' political map-drawing process.
