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.
