10 ILCS 5/23-1.13a

If any of the powers or duties to be exercised or performed by the Supreme Court under Sections 23-1.1a through 23-1.12a may not constitutionally be exercised or performed by the Supreme Court by reason of jurisdictional limitations, then Sections 23-1.1a through 23-1.12a shall nonetheless continue to govern contests of elections for elected officers provided for in Article V of the Constitution, and in such event the Supreme Court shall, pursuant to its general administrative and supervisory powers, assign to a circuit court those adjudicatory powers and duties with respect to such a contest as may not be exercised or performed by the Supreme Court, subject to appropriate judicial review.
