Illinois Statutes Chapter 10. Elections § 5/6A-1. Establishment

§ 6A-1. (a) Any county in which there is no city, village or incorporated town with a board of election commissioners may establish a county board of election commissioners either (1) by ordinance of the county board or (2) by vote of the electors of the county in accordance with subsection (a) of Section 6A-2.

The fact that some territory in a county is within the corporate limits of a city, village or incorporated town with a board of election commissioners does not prevent that county from establishing a county board of election commissioners in accordance with this Article if no portion of such city, village or incorporated town was within the county at the time of the establishment of the board of election commissioners for such city, village or incorporated town. If such a county establishes a county board of election commissioners pursuant to this Article, the county board of election commissioners shall, with respect to the territory in the county within the corporate limits of the city, village or incorporated town, supersede the board of election commissioners of that city, village or incorporated town.

(b) Any county with a population of more than 700,000 persons as of the 2010 federal decennial census that borders another state and borders no more than 2 other Illinois counties, shall be subject to a county board of election commissioners beginning 90 days after the effective date of this amendatory Act of the 98th General Assembly.

(c) Any county with a population of less than 200,000 but more than 175,000 persons as of the 2010 federal decennial census in which a city, village, or incorporated town with a board of election commissioners is located may establish a county board of election commissioners by vote of the electors of the county in accordance with subsection (b) of Section 6A-2. If such a county establishes a county board of election commissioners, the county board of election commissioners, with respect to the territory in the county within the corporate limits of the city, village, or incorporated town, shall supersede the board of election commissioners of that city, village, or incorporated town.
