One potential change this year could come from a constitutional referendum petition circulating in IL. The main purpose is to enact legislative term limits, but in order to get around previous court decisions restricting the form of petitions, it also would change the IL House to 123 and the Senate to 41.
A court decision that actually makes a citizen initiative consist of more than one subject? Odd. Can you explain further?
Article XIV of the 1970 IL Constitution has this section for citizen initiative:
I've bolded the critical sentence. Article IV is the legislative article so its the only one that can be changed. The IL Supremes ruled that the conjunction "and" means both clauses must be true, so initiatives must be constructed to change both the structure and procedures of the General Assembly.
