Beyond Legislation: How Agencies Make Law

Most people understand that Congress passes laws. Fewer realize that a significant portion of the rules governing daily life — from workplace safety standards to food labeling requirements to financial regulations — come not from Congress directly, but from administrative agencies exercising delegated rulemaking authority.

When an agency issues a binding rule, it is in effect issuing a regulatory decree: an official, enforceable mandate with the force of law. Understanding how this process works is essential for businesses, advocates, researchers, and any citizen who wants to engage with how government actually operates.

The Legal Foundation: Delegated Authority

Agencies cannot simply make up rules on their own. Their authority flows from enabling statutes — laws passed by Congress that create an agency and grant it specific powers. For example, the Clean Air Act grants the Environmental Protection Agency authority to set air quality standards. The Occupational Safety and Health Act grants OSHA authority to regulate workplace hazards.

This delegation of legislative power is the constitutional basis for administrative rulemaking — and also its primary legal vulnerability. If an agency acts beyond the scope of its enabling statute, courts can strike down the rule.

The Notice-and-Comment Rulemaking Process

Most significant federal rulemaking in the United States follows the process established by the Administrative Procedure Act (APA) of 1946. This "notice-and-comment" or "informal" rulemaking process has several stages:

  1. Proposed Rule (NPRM): The agency publishes a Notice of Proposed Rulemaking in the Federal Register, explaining the proposed rule and its legal basis.
  2. Public Comment Period: The public — including individuals, businesses, trade groups, and advocacy organizations — has an opportunity to submit written comments. This period typically lasts 30 to 60 days, though it can be longer for complex rules.
  3. Agency Review: The agency must review and consider all substantive comments received. It is not required to adopt every suggestion, but it must demonstrate that it genuinely considered the public input.
  4. Final Rule: The agency publishes the final rule in the Federal Register, including a "preamble" responding to significant comments and explaining the rationale for the final text.
  5. Effective Date: Final rules typically take effect 30 days after publication, giving affected parties time to prepare for compliance.
  6. Codification: The rule is incorporated into the Code of Federal Regulations (CFR), becoming part of the permanent body of federal administrative law.

Informal vs. Formal Rulemaking

The notice-and-comment process described above is "informal" rulemaking — the most common type. Formal rulemaking, required only when a statute specifically calls for rules "on the record after opportunity for an agency hearing," involves a more trial-like proceeding with witnesses and cross-examination. It is rarely used due to its procedural complexity.

Interim and Emergency Rules

Agencies sometimes need to act quickly. In urgent situations, agencies can issue interim final rules — rules that take effect immediately but still invite public comment for possible future modification. These are used when delay would pose health, safety, or other significant public risks.

How to Participate in Rulemaking

Public participation in rulemaking is a genuine right — and an underutilized one. Anyone can:

  • Monitor proposed rules at Regulations.gov (for U.S. federal rules).
  • Submit comments during the open comment period — comments from informed stakeholders carry particular weight.
  • Attend any public hearings or meetings the agency schedules.
  • Challenge final rules in federal court if the agency exceeded its authority or failed to follow proper procedure.

State-Level Rulemaking

Each U.S. state has its own administrative procedure act and rulemaking process, broadly similar to the federal model. State agencies publish proposed rules in official administrative registers, conduct comment periods, and codify final rules in state administrative codes. Businesses operating across multiple states must track these processes in each relevant jurisdiction.

The Bottom Line

Regulatory rulemaking is a structured, participatory process — not an arbitrary exercise of bureaucratic power. Understanding its mechanics helps citizens, businesses, and advocates engage meaningfully with the rules that govern their lives, and to hold agencies accountable when those rules are made improperly.
