Synopsis As Introduced Proposes to amend the Legislature Article of the Illinois Constitution. Provides that the Senate by resolution (instead of the General Assembly by law) shall divide the Legislative Districts into 3 groups for the election of Senators. Provides that Legislative and Representative Districts shall reflect minority voting strengths and consider communities of interest (as well as be compact, contiguous, and substantially equal in population). Provides that, by June 30 in the year following each Federal decennial census year, the Senate and House, each by resolution adopted by two-thirds of the members elected, shall redistrict the Legislative and Representative Districts, respectively. If a resolution is not filed with the Secretary of State by June 30, provides that a Legislative District or a Representative District Redistricting Commission has until July 31 to redistrict the Legislative Districts or Representative Districts, as applicable. If a Commission fails to redistrict, requires the Chief Justice and another Judge of the Supreme Court to appoint a Special Master, who must be a retired federal judge, to redistrict by September 5. Requires Special Masters to use a computer program designated by the State Board of Elections and sets forth the requirements for that program. Limits the jurisdiction of the Supreme Court in redistricting actions. Makes other changes. Effective upon being declared adopted.
