(10 ILCS 92/5) Sec. 5. Findings. In enacting this redistricting plan, the General Assembly finds and declares all of the following: (a) Under Article IV, Section 3 of the Illinois Constitution of 1970, in the year following each federal decennial census year, the General Assembly is required to redistrict the Legislative Districts and the Representative Districts by law by June 30.
