Constitution of the State of Illinois Art. XIV, § 2. Amendments by General Assembly

(a) Amendments to this Constitution may be initiated in either house of the General Assembly. Amendments shall be read in full on three different days in each house and reproduced before the vote is taken on final passage. Amendments approved by the vote of three-fifths of the members elected to each house shall be submitted to the electors at the general election next occurring at least six months after such legislative approval, unless withdrawn by a vote of a majority of the members elected to each house.

(b) Amendments proposed by the General Assembly shall be published with explanations, as provided by law, at least one month preceding the vote thereon by the electors. The vote on the proposed amendment or amendments shall be on a separate ballot. A proposed amendment shall become effective as the amendment provides if approved by either three-fifths of those voting on the question or a majority of those voting in the election.

(c) The General Assembly shall not submit proposed amendments to more than three Articles of the Constitution at any one election. No amendment shall be proposed or submitted under this Section from the time a Convention is called until after the electors have voted on the revision or amendments, if any, proposed by such Convention.
