Synopsis As Introduced Proposes to amend the Legislature Article of the Illinois Constitution. Provides that provisions concerning legislative redistricting apply to Congressional Districts. Requires that districts, in addition to being compact, contiguous, and substantially equal in population, must also comply with the federal Constitution and law, provide racial and ethnic minorities with equal opportunity to participate in the political process, provide racial and ethnic minorities who constitute less than a voting-age majority of a district with an opportunity to substantially influence the outcome of an election, respect geographic integrity of units of local government, respect communities sharing common social or economic interests, and not discriminate against or in favor of any political party or individual. Replaces the current method of legislative redistricting with the following: a 16-member commission, appointed by the Chief Justice of the Supreme Court and the most senior Supreme Court Judge of a different political party in accordance with specified criteria, shall adopt and file with the Secretary of State redistricting plans for Legislative, Representative, and Congressional Districts following a series of public hearings by August 1 of the year following a federal decennial census; permits the public to submit maps during the map drawing process for consideration by the Commission; and, if a redistricting plan is not adopted by August 1 of the year following a federal decennial census, then a seventeenth member shall be appointed to the Commission and redistricting plans shall be filed by September 1. Adds provisions concerning the membership of the Commission and budgetary matters related to the Commission. Removes the requirement for each Legislative District to be divided into two Representative Districts. Effective upon being declared adopted and applicable to redistricting beginning in 2021 and to the election of General Assembly members beginning in 2022.
