How frequently is the Illinois Constitution reviewed or amended?

The Illinois Constitution is reviewed every twenty years, which is a systematic process designed to ensure that the constitution remains relevant and reflective of the needs and values of the citizens of Illinois. This twenty-year cycle allows for a comprehensive examination of the constitution's provisions and the opportunity for amendments if deemed necessary by a constituent referendum.

During this review, a convention can be called to propose amendments or changes. If voters decide not to convene a convention, the existing constitution remains in effect until the next review cycle. This approach balances stability in governance with the need for potential updates, thereby ensuring that the document governing the state can adapt to changing societal contexts without frequent disruptions.

While other options suggest shorter intervals or more frequent adaptations, the established framework for constitution review in Illinois is centered on the twenty-year cycle to maintain a structured and orderly process for any amendments.
