Constitution of the State of Illinois Art. IV, § 8. Passage of Bills

(a) The enacting clause of the laws of this State shall be: “Be it enacted by the People of the State of Illinois, represented in the General Assembly.”

(b) The General Assembly shall enact laws only by bill. Bills may originate in either house, but may be amended or rejected by the other.

(c) No bill shall become a law without the concurrence of a majority of the members elected to each house. Final passage of a bill shall be by record vote. In the Senate at the request of two members, and in the House at the request of five members, a record vote may be taken on any other occasion. A record vote is a vote by yeas and nays entered on the journal.

(d) A bill shall be read by title on three different days in each house. A bill and each amendment thereto shall be reproduced and placed on the desk of each member before final passage.

Bills, except bills for appropriations and for the codification, revision or rearrangement of laws, shall be confined to one subject. Appropriation bills shall be limited to the subject of appropriations.

A bill expressly amending a law shall set forth completely the sections amended.

The Speaker of the House of Representatives and the President of the Senate shall sign each bill that passes both houses to certify that the procedural requirements for passage have been met.
