Initiative process availability[edit]

See also: Laws governing local ballot measures in Illinois

Illinois law provides for an advisory (non-binding, no legal effect) initiative process on questions of public policy. A binding referendum is required on limited matters, such as tax levies and bonds (Chap 10 Election Code, Art. 28). Residents of home-rule counties and cities may change their form of government or revert to general law governance by initiative. While mostly formal, this process can have some effects on policy. For example, under the general law, city governments face greater restrictions on raising taxes. Thus, switching from home-rule to general law can help limit tax increases.[2][3]
