# Informal Rulemaking | Intro to Law and Legal Process

## Definition

Informal rulemaking is the way an administrative agency writes regulations through notice-and-comment instead of formal hearings. In Intro to Law and Legal Process, it is the main rulemaking process you use to see how agencies turn statutory authority into workable rules.

## What It Is

Informal rulemaking is the standard way many administrative agencies make rules in Intro to Law and Legal Process. It usually means the agency publishes a proposed rule, invites written public comments, reviews those comments, and then issues a final rule.

The most common version is called notice-and-comment rulemaking. First, the agency sends out a Notice of Proposed Rulemaking, which tells the public what the agency plans to do and why. Then people, companies, advocacy groups, and other agencies can respond with comments, objections, data, or alternative language.

This process is called "informal" because it does not require the full trial-like hearing procedure used in formal rulemaking. There is no judge-like hearing officer taking evidence the way you might see in a courtroom setting. Instead, the agency builds the rule through written participation and internal review, which makes the process faster and more flexible.

That speed matters because agencies often need to respond to changing conditions, new statutes, or practical problems in enforcement. If Congress gives an agency authority to regulate a subject, the agency often has to fill in the details, like setting safety standards, filing deadlines, disclosure requirements, or licensing procedures. Informal rulemaking is how those details become actual regulations with legal force.

The public comment period is not just a formality. Agencies are expected to read significant comments, especially ones that raise legal problems, technical flaws, or evidence the agency ignored. If the agency brushes aside important comments without explaining itself, the final rule can be vulnerable to challenge under administrative procedure principles.

A useful way to think about informal rulemaking is that it sits between pure agency discretion and full courtroom procedure. The agency still drives the process, but the public gets a chance to shape the outcome. That balance is why Intro to Law and Legal Process often treats informal rulemaking as the workhorse of modern administrative law.

## Why It Matters

Informal rulemaking matters because it shows how agencies actually turn broad laws into specific rules people have to follow. Congress usually writes the big policy, but agencies write the details, and those details can shape everyday life in areas like workplace safety, environmental compliance, consumer protection, and professional licensing.

This term also helps you see the difference between making law and applying law. A statute may say an agency should protect the public, but informal rulemaking decides what that protection looks like in practice. That makes it a core concept for understanding administrative power, because the real regulatory impact often comes from the rule itself, not just the original statute.

It also gives you a clean way to analyze process questions. If a professor asks whether an agency acted properly, you can ask: Did the agency give notice? Did it accept comments? Did it explain the final rule? Those steps show whether the agency used a legitimate procedure and whether its rule is likely to survive review.

In class, informal rulemaking is also a good place to spot the tension between efficiency and participation. The process is faster than a formal hearing, but it still gives outside groups a chance to influence the final regulation. That tradeoff comes up again and again in debates about whether agencies are too powerful or not accountable enough.

## Connections

### [Notice-and-Comment Rulemaking](/introduction-law-legal-process/key-terms/notice-and-comment-rulemaking)

This is the most common form of informal rulemaking. The agency publishes a proposed rule, collects written comments, and then revises or finalizes the rule. If you see a question about public participation, this is usually the procedure being described.

### Notice of Proposed Rulemaking

The Notice of Proposed Rulemaking is the starting signal for informal rulemaking. It tells the public what rule the agency is considering and gives enough detail for people to respond intelligently. In practice, this document frames the whole comment process and shapes what issues the agency must address later.

### Formal Rulemaking

Formal rulemaking is the more rigid cousin of informal rulemaking. It uses hearing-style procedures and much more structure, so it is slower and less common. Comparing the two helps you see why agencies usually choose the informal route unless a statute demands more procedure.

### Good Cause Exemption

The good cause exemption can let an agency skip notice and comment when waiting would be impractical or harmful. That makes it a major exception to informal rulemaking, not a separate rulemaking style. It often appears in questions about emergencies, urgent public needs, or fast-moving regulatory problems.

## On the AP Exam

A short-answer question or case prompt may ask you to trace the steps of an agency rule from proposal to final adoption. You would identify informal rulemaking by looking for a proposed rule, a public comment period, and a final regulation issued without a formal hearing.

On a quiz, you might be given a scenario where an environmental, labor, or consumer agency sets a new standard and asks what procedure it used. The right move is to spot the notice-and-comment process and explain why it fits the facts. If the prompt includes public complaints or agency responses, use those details to show how the comments shaped the final rule.

In an essay or class discussion, you may need to compare informal rulemaking with formal rulemaking or a shortcut like the good cause exemption. The strongest answers name the procedure, then explain the tradeoff between speed, transparency, and public input.

## informal rulemaking vs Formal Rulemaking

These are easy to mix up because both are ways agencies make regulations. Informal rulemaking relies mainly on notice and written comments, while formal rulemaking uses a much more hearing-like process. If the question mentions a trial-style record or formal hearings, it is probably not informal rulemaking.

## Key Takeaways

- Informal rulemaking is the main way many agencies create regulations without using a formal hearing process.
- The usual procedure is notice and comment, where the agency proposes a rule, takes written public feedback, and then issues a final version.
- This process is faster than formal rulemaking, which is why agencies rely on it for many everyday regulatory tasks.
- The public comment stage matters because agencies are expected to consider significant feedback before finalizing the rule.
- If you see a scenario with a proposed rule, public responses, and a final regulation, you are probably looking at informal rulemaking.

## FAQs

### What is informal rulemaking in Intro to Law and Legal Process?

Informal rulemaking is the agency process for creating regulations through notice and comment rather than a formal hearing. It is the most common way agencies turn broad legal authority into specific rules. In this course, it shows how administrative agencies make the details that put statutes into action.

### Is informal rulemaking the same as notice-and-comment rulemaking?

They are usually used almost interchangeably in this context. Informal rulemaking is the broader process, and notice-and-comment is the core procedure inside it. If a rulemaking question mentions a proposed rule and written public comments, that is the version you should think of.

### How is informal rulemaking different from formal rulemaking?

Formal rulemaking is much more procedure-heavy and resembles a hearing, while informal rulemaking is based mainly on written notice and comments. Most agencies prefer the informal process because it is faster and more practical. The difference often shows up in questions about speed, transparency, and how much public participation the law requires.

### How do I identify informal rulemaking in a case or scenario?

Look for a proposed regulation, a public comment period, and a final rule issued by an agency. If the facts mention written feedback from the public, trade groups, or advocacy organizations, that is a strong sign of informal rulemaking. If the prompt mentions a formal hearing record, you are probably dealing with a different process.
