How can the Illinois Constitution be amended?

The process for amending the Illinois Constitution is outlined in the document itself. It allows for amendments to be proposed in two primary ways: either by a three-fifths vote in both the Illinois Senate and the Illinois House of Representatives or by calling a constitutional convention. This dual mechanism ensures that amendments have significant support from the legislative branch or are derived from a broader public interest through a convention, thereby maintaining a high threshold for making changes to the foundational legal document of the state.

The requirement for a three-fifths majority in both houses means that there must be considerable bipartisan support for any proposed amendment, reflecting a commitment to careful deliberation when altering the Constitution. The option for a constitutional convention, on the other hand, provides a platform for a more comprehensive review and potential overhaul of the constitutional framework if deemed necessary by the populace, emphasizing the democratic principle that significant changes should involve the collective input of the people.

Other options present methods for voting or proposals that do not align with the formal amendment process as established by the Illinois Constitution.
