Why the Best Regulation Is the One You Can Explain to a Stranger on the Bus
Regulatory forensics starts with a basic test: can you explain a rule to a stranger on a bus without reaching for a flowchart? If not, the rule may still be lawful, but it is probably not legible. Legibility is the quality that lets a small business owner, a policy analyst, or a graduate student trace who pays, who chooses, and who writes the rules in a specific U.S. federal regulatory action. It sits alongside related concepts such as notice-and-comment procedure, regulatory impact analysis, administrative record, and cost-benefit accounting. For readers of this blog, legibility is not a stylistic preference. It is an analytical tool for determining whether a Federal Register notice actually does what its preamble claims.
This article examines why the best regulation is the one you can explain to a stranger on the bus. It does not argue that all rules should be short. It argues that rules should be traceable. A rule can be long and still be legible if its obligations, definitions, and compliance pathways are recoverable from the text. A rule can be short and still be opaque if it hides discretion in cross-references, undefined terms, or agency guidance that never appeared in the docket.
The Legibility Standard in Regulatory Analysis
Legibility is not the same as simplicity. A tax regulation can run hundreds of pages and still be legible if a reader can identify the statutory authority, the affected class, the compliance date, and the enforcement mechanism. A three-page interpretive rule can be illegible if it relies on an unpublished manual or a private letter ruling that the public cannot easily retrieve.
In practice, regulatory analysts often use a four-part test. First, can you state the rule’s operative command in one sentence? Second, can you identify who must comply? Third, can you identify what changes for that party on the effective date? Fourth, can you identify the agency office that will answer questions about the rule? If any of those four answers requires a chain of cross-references longer than two steps, the rule has a legibility problem.
Why Legibility Matters for Small Business Owners
Small business owners rarely read the Federal Register for pleasure. They encounter rules through trade association summaries, accountant memos, or state licensing boards. When the underlying rule is legible, those secondary sources can be checked against the primary text. When the rule is opaque, the small business owner is forced to rely on intermediaries who may themselves be guessing.
Consider a hypothetical Occupational Safety and Health Administration standard that requires employers to provide a “suitable” training program. If the rule does not define “suitable,” the employer cannot know whether a 20-minute video satisfies the obligation. The employer may comply in good faith and still face a citation because an inspector interprets “suitable” differently. The rule is short, but it is not legible. The cost of that ambiguity falls on the party with the fewest resources to litigate the meaning.
Why Legibility Matters for Policy Analysts
Policy analysts use legibility as a proxy for administrative accountability. When a rule is legible, the analyst can compare the agency’s stated rationale with the actual regulatory text. When a rule is opaque, the analyst cannot easily tell whether the agency is implementing a statute or inventing a policy.
For example, an analyst reviewing an Environmental Protection Agency rule might ask whether the agency’s cost estimates match the compliance options described in the regulatory text. If the text refers to “best management practices” without listing them, the analyst cannot verify the cost model. The rule may be supported by a 200-page regulatory impact analysis, but the analysis is untethered from the text. Legibility is what connects the preamble to the operative provisions.
The Anatomy of an Illegible Rule
Illegible rules tend to share certain features. They rely on undefined terms. They incorporate external documents by reference without summarizing the relevant portions. They delegate key decisions to guidance that has not gone through notice and comment. They use conditional language that makes compliance contingent on facts the regulated party cannot observe.
One common pattern is the “double cross-reference.” A rule says that a facility must comply with “the requirements of subpart C.” Subpart C says that a facility must comply with “the applicable standards in part 60.” Part 60 says that a facility must comply with “the methods approved by the Administrator.” By the time the reader reaches the actual obligation, the rule has passed through three layers of indirection. Each layer is an opportunity for the agency to change the meaning without changing the text.
The Role of the Administrative Record
The administrative record is the paper trail of a rulemaking. It includes the notice of proposed rulemaking, public comments, agency responses, and the final rule. A legible rule is one whose meaning can be reconstructed from that record. An illegible rule is one whose meaning depends on documents outside the record, such as internal agency memoranda or post-promulgation guidance.
Courts sometimes enforce this principle through the doctrine of “arbitrary and capricious” review. An agency must explain its decision in the record. If the explanation is missing or contradictory, the rule may be remanded. But judicial review is a blunt instrument. It catches the most egregious failures of explanation, not the everyday ambiguities that burden regulated parties.
Legibility and the Notice-and-Comment Process
Notice-and-comment rulemaking is the primary mechanism for public participation in federal regulation. The Administrative Procedure Act requires agencies to publish a notice of proposed rulemaking, accept public comments, and respond to significant comments in the final rule. The process is designed to produce legible rules because it forces agencies to articulate their reasoning in public.
But the process only works if the agency’s response to comments is substantive. An agency that says “we disagree” without explaining why has not made the rule more legible. It has simply recorded a disagreement. The best final rules are those in which the agency’s response to comments clarifies the regulatory text, not just the preamble.
Example: The Federal Register Notice as a Legibility Test
Imagine a Federal Register notice that proposes to amend a definition of “small manufacturer.” The notice says the change will “reduce burden” and “promote consistency.” A legible notice would explain which manufacturers are affected, how the new definition changes their obligations, and what data the agency used to estimate the burden reduction. An illegible notice would repeat the statutory language without explaining how the agency interprets it.
The difference matters for commenters. A legible notice allows a commenter to respond with specific evidence: “Your burden estimate assumes a 10-hour compliance cost, but our members report 40 hours.” An illegible notice forces the commenter to guess what the agency is actually proposing. The comment period becomes a game of blind man’s bluff.
The Cost of Illegibility
Illegibility is not free. It imposes costs on regulated parties, on agencies, and on the public. Regulated parties must hire lawyers and consultants to interpret the rule. Agencies must field questions and issue guidance to clarify what the rule meant. The public must trust that the agency is applying the rule consistently, even when the text does not make consistency easy to verify.
These costs are often invisible in the regulatory impact analysis. An agency may estimate the cost of compliance without estimating the cost of interpretation. But interpretation costs are real. A small business owner who spends 20 hours trying to understand a rule has lost 20 hours of productive time. A policy analyst who cannot trace a rule’s requirements has lost the ability to hold the agency accountable.
Legibility and Regulatory Uncertainty
Regulatory uncertainty is a term that economists use to describe the risk that a rule will change or be interpreted differently over time. Legibility reduces uncertainty because it makes the rule’s meaning stable and recoverable. An illegible rule is a source of uncertainty even if the text never changes, because the agency’s interpretation can shift without notice.
For small business owners, uncertainty is a planning problem. A restaurant owner who does not know whether a new food safety rule applies to her operation cannot decide whether to invest in new equipment. A manufacturer who does not know whether an emissions standard applies to his facility cannot decide whether to sign a long-term supply contract. Legibility is not just about compliance. It is about the ability to make decisions under a known set of rules.
How to Test a Rule for Legibility
There is a practical method for testing a rule’s legibility. It does not require a law degree. It requires a pencil, a copy of the rule, and a willingness to follow cross-references.
First, read the rule’s statement of purpose. Does it say what the rule is supposed to accomplish? Second, read the definitions section. Are the key terms defined? Third, read the operative provisions. Do they state the obligation in plain language? Fourth, read the compliance dates. Are they specific? Fifth, read the enforcement provisions. Do they identify the agency office responsible for interpretation?
If the rule fails any of those five tests, it has a legibility problem. The problem may be minor, or it may be severe. But it is a problem that should be noted in any regulatory analysis.
The Bus Test in Practice
The bus test is a thought experiment. Imagine you are sitting next to a stranger on a bus. The stranger asks what a new federal rule does. You have 30 seconds to answer. If you can answer in a way that the stranger understands, the rule is legible. If you cannot, the rule is not.
The bus test is not a substitute for careful analysis. It is a diagnostic tool. It forces you to identify the rule’s core command and state it without jargon. If you cannot do that, you probably do not understand the rule yourself. And if you do not understand the rule, you cannot analyze it.
Legibility and the Future of Regulatory Forensics
Regulatory forensics is the practice of tracing who pays, who chooses, and who writes the rules in a specific federal regulatory action. Legibility is the foundation of that practice. Without legibility, the forensic analyst cannot trace the rule’s effects. With legibility, the analyst can compare the agency’s stated rationale with the actual text, identify the winners and losers, and explain the rule to a non-specialist.
This blog will return to the legibility standard in future posts. A natural next step is a case study of a specific Federal Register notice that fails the bus test. Another is a glossary of terms that agencies use to hide discretion, such as “as appropriate,” “to the extent practicable,” and “the Administrator may.” A third is a reader question column: send a rule you cannot explain, and we will trace it together.
Frequently Asked Questions
What does it mean for a regulation to be legible?
A legible regulation is one whose operative command, affected parties, compliance dates, and enforcement mechanism can be identified from the text without relying on unpublished guidance or multi-step cross-references. Legibility is not the same as brevity. A long rule can be legible if its structure is clear and its terms are defined.
Why do agencies write illegible rules?
Agencies write illegible rules for several reasons. Sometimes the underlying statute is ambiguous, and the agency is trying to preserve flexibility. Sometimes the agency is responding to conflicting comments and chooses vague language to avoid committing to a position. Sometimes the agency is simply not aware of how the rule reads to a non-specialist. None of these reasons makes the rule easier to comply with.
How can a small business owner respond to an illegible rule?
A small business owner can respond by filing a comment during the notice-and-comment period that asks the agency to clarify the specific provision. The comment should quote the ambiguous language, explain the practical problem it creates, and ask a direct question. If the rule is already final, the owner can request an interpretation from the agency’s designated contact or ask a trade association to seek clarification. The key is to put the ambiguity on the record.
Is there a legal requirement that rules be legible?
There is no standalone legal requirement that rules be legible. But the Administrative Procedure Act requires agencies to provide notice of proposed rulemaking and to respond to significant comments. The arbitrary and capricious standard requires agencies to explain their decisions. A rule that is so opaque that its meaning cannot be determined may be vulnerable to challenge on those grounds. In practice, however, courts defer to agency interpretations of their own rules unless the interpretation is plainly erroneous.
