This document summarizes a voter petition in Illinois seeking to impose legislative term limits through a constitutional amendment. It discusses the relevant section of the Illinois Constitution, the three methods for amending the constitution, and two important Illinois Supreme Court cases on this issue. Based on the case law, the petition is likely invalid because term limits do not qualify as a strictly "structural and procedural" change allowed through the voter initiative process under the constitution. While voters strongly support term limits, the courts have interpreted the rules for amendments as prohibiting this type of substantive change through a petition.
