Increasingly, state regulations are implemented and exercised by the administrative discretion of state bureaucracies. To combat this, state legislatures now routinely seek to regain their preeminence as lawmakers by overseeing administrative rulemaking authority. This oversight is frequently conducted through a process known as "rules review." Regulating the Regulators presents an introduction to this legislative oversight of administrative rulemaking. Rules review encourages the responsible exercise of rulemaking authority by requiring legislative scrutiny of proposed regulations prior to final adoption by the issuing agency. Bowers examines this process through an in-depth case-study of the Illinois General Assembly.
