According to the Illinois Constitution, what is the maximum number of subjects a bill can contain?

Under the Illinois Constitution, a bill is required to contain only one subject. This principle is established to ensure clarity and prevent the practice of "logrolling," where unrelated issues are bundled together to secure legislative support for a controversial measure. By limiting a bill to a single subject, the legislative process is made more transparent, and legislators and voters can better understand the implications of each piece of legislation. This helps maintain accountability, as each bill must stand on its own merits rather than being hidden within a larger package of unrelated provisions.
