McCombie v. Illinois State Board of Elections

Refused to accept an original action by the state’s house majority leader and voters, claiming that house districts drawn in 2021 are partisan and not compact, finding the complaint untimely and barred by laches because the plaintiffs did not exercise due diligence in bringing suit. The dissenting justice said the majority was wrong to discredit the plaintiffs’ argument that they had to collect data from multiple election cycles. Because the Illinois high court has never adjudicated a state constitutional partisan gerrymandering claim before, he opined, it has not provided guidance on whether such data — which was required for federal constitutional claims until the U.S. Supreme Court in Rucho v. Common Cause (2019) ruled such claims cannot be brought — is applicable for a state constitutional challenge.
