After debate, the House passed the bill on April 11 and it arrived in the House on May 21, and both chambers agreed to the final version of the legislation on May 29. The bill was sent to the governor and signed into law on Aug. 16. The law is scheduled to go into effect on Jan. 1, 2020.
Illinois legislature enacts laws through bills that can be introduced in either the state House of Representatives or the state Senate. Either chamber of the legislature can reject or amend a bill before it becomes law. Legislators sometimes sponsor "shell bills" devoid of substantive provisions, introduced with the intention of being amended later to include actual legislation.
