In December 1970, Illinois citizens exercised their right to vote and approved a new Constitution.
Article 14, Section 2 of the Constitution grants power to the General Assembly to initiate amendments to it and articulates the process by which amendments can be made. Proposed amendments can be introduced in either house of the General Assembly, and if three-fifths of the members of each house approve the amendment, then at the next general election, the voters determine if the amendment will be approved or disapproved.
