The nature and scope of administrative rulemaking is a topic for ongoing debate. One of the main functions of administrative agencies is to create regulations. Over the past several decades, the volume of the Code of Federal Regulations far surpasses the laws passed by Congress. How are these agencies accountable to the American public? What are tradeoffs for relying on agency expertise instead of Congressional legislating? This series discusses how agency rulemaking works in practice: the scope of agencies' authority to write regulations, core processes of agency rulemaking (notice and comment rulemaking), the review and scrutiny that rules are subject to, and how agency rulemaking fits in with the democratic process.
