Who has the ultimate authority in determining the need for a constitutional convention in Illinois?

The ultimate authority in determining the need for a constitutional convention in Illinois lies with the citizens through voting. This process is rooted in democratic principles, allowing the electorate to directly influence significant changes to the state’s constitution. According to Article XIV of the Illinois Constitution, a question regarding whether to hold a constitutional convention can be placed on the ballot, and it is up to the citizens to vote on it. This mechanism ensures that the populace has the power to initiate comprehensive changes to the state's foundational legal document, underscoring the principle of popular sovereignty.

While the General Assembly and the governor play crucial roles in the legislative process and may influence governance, the decision to convene a constitutional convention ultimately reflects the will of the people, as determined through a voting process. The Supreme Court does not have the authority to call for a convention; its role is primarily to interpret the law rather than initiate constitutional change. Thus, the citizens' ability to vote on this matter exemplifies the participatory aspect of governance in Illinois.
