Legislation in Illinois proceeds through a multi-phase process, beginning with introduction in the House or Senate, followed by committee review and floor debate, with votes required in both legislative chambers. After passage, bills proceed to the governor, who may sign or veto them. The General Assembly works on a two-year cycle; most proposals do not make it all the way through to become law.
