Under the bill, "state agency" would mean a department, board, commission, office, agency, authority, or other unit of State government, including a State institution of higher education. "Unit of local government" would mean a political subdivision of the State, including school districts, community college districts, intermediate school districts, public school academies, cities, villages, townships, counties, and authorities, if the political subdivision had as its primary purpose the provision of local governmental service for citizens in a geographically limited area of the State and had the power to act primarily on behalf of that area.
