Which of the following best describes the Illinois Compiled Statutes?

The Illinois Compiled Statutes is a comprehensive compilation of the state's laws. This collection serves as the official codification of legislative enactments in Illinois, systematically organizing statutes by subject matter, making the laws accessible to the public. The statutes cover a wide range of topics pertinent to the citizens and governance of Illinois, such as criminal law, civil law, and administrative procedures.

In contrast, a directory of state agencies does not encompass the breadth of legal provisions; it simply lists the various agencies without detailing the laws they enforce. A summary of court cases is fundamentally different as it pertains to judicial decisions and interpretations of law rather than codified statutes. Lastly, a guide for tax regulations typically provides information on tax obligations and processes, rather than presenting the complete legal framework within which those regulations are established. Therefore, the best description of the Illinois Compiled Statutes is that it is a thorough compilation of the state's laws.
