Rule by Decree — How Federal Agencies Are Quietly Legislating Without Congress

The Rulemaking Loophole Nobody in Washington Wants to Close

In theory, the American legislative process is straightforward: Congress writes the law, the President signs it, and executive agencies implement it. In practice, that civics-textbook clarity has been replaced by something far more troubling — a system in which federal bureaucracies treat vague statutory language as a blank check to invent sweeping policy on their own authority, insulated from electoral accountability and largely immune to meaningful public challenge.

The pattern is consistent and deliberate. An agency identifies a policy goal — tighter emissions standards, expanded workplace mandates, broader definitions of employment classification — that it knows Congress either has not approved or would not approve. Rather than waiting for legislation, the agency issues what it calls an "interpretive guidance," a "final rule," or an "enforcement policy." These documents carry the practical force of law, binding businesses and individuals to requirements that no elected representative ever voted on.

This is the regulatory whack-a-mole game. Congress swings the mallet at one overreach, and three more appear elsewhere in the Federal Register.

Exhibit A: The EPA's Elastic Mandate

No agency better illustrates this dynamic than the Environmental Protection Agency. The Clean Air Act of 1970 gave the EPA authority to regulate "air pollutants" — language written by a Congress that was thinking about smog and industrial emissions, not carbon dioxide exhaled by every living organism on the planet.

Decades later, the EPA used that same statutory text to assert jurisdiction over greenhouse gas emissions from essentially every sector of the American economy. The Supreme Court pushed back in West Virginia v. EPA (2022), ruling 6-3 that the agency had exceeded its authority by attempting to restructure the nation's entire power grid through regulatory fiat. The majority invoked what is now known as the "major questions doctrine" — the principle that agencies cannot claim transformative regulatory power from ambiguous statutory grants without clear congressional authorization.

But the ruling, while significant, was not a cure. The EPA has continued pursuing aggressive climate regulation through alternative regulatory pathways, issuing new rules on tailpipe emissions and power plant standards that push the same policy objectives through different statutory hooks. The goal remains unchanged; only the legal wrapper has been swapped.

The Labor Department's Classification Carousel

The Department of Labor has played the same game with worker classification rules. The distinction between an "employee" and an "independent contractor" carries enormous economic consequences — for gig economy workers, for small businesses, for freelancers who have voluntarily chosen flexible arrangements. Congress has never passed comprehensive legislation definitively resolving how that distinction should be drawn.

That silence has become an invitation. The Biden-era Labor Department issued a final rule in January 2024 replacing a Trump-era standard with a multi-factor "economic reality" test that made it significantly harder for businesses to classify workers as independent contractors. The rule did not emerge from any new congressional statute. It emerged from the agency's reinterpretation of the Fair Labor Standards Act — a law passed in 1938 that says nothing specific about gig platforms, app-based work, or the modern freelance economy.

The practical effect was to expose millions of businesses to reclassification liability under rules they had not anticipated and that Congress had never explicitly endorsed. Several federal courts have since issued rulings challenging the rule's scope, but litigation takes years, and businesses must navigate compliance uncertainty in the interim.

OSHA and the Mandate Mechanism

OSHA's attempted COVID-19 vaccine mandate for private employers with 100 or more workers stands as perhaps the most dramatic recent example of agency overreach. The mandate — which would have affected roughly 84 million American workers — was issued not through legislation but through an emergency temporary standard, a mechanism designed for acute, specific workplace hazards.

The Supreme Court blocked it in January 2022, with the majority noting that OSHA had never before claimed the power to impose a vaccine mandate and that such a sweeping public health measure required explicit congressional authorization. The Court's language was pointed: "It is telling that OSHA, in its half century of existence, has never before adopted a broad public health regulation of this kind."

The mandate was dead. But the underlying ambition — to use agency authority to accomplish what Congress had not authorized — survived the ruling and has resurfaced in different regulatory contexts ever since.

The Strongest Counterargument — and Why It Falls Short

Defenders of expansive agency rulemaking make a reasonable point: Congress legislates in broad strokes because it lacks the technical expertise to write granular regulatory standards for every industry and environmental condition. Agencies employ scientists, economists, and specialists. Flexibility, the argument goes, is a feature, not a bug.

This is not a frivolous position. But it proves too much. The question is not whether agencies need some interpretive discretion — of course they do. The question is whether that discretion extends to creating entirely new substantive policy in areas where Congress has been deliberately silent or where the political process has reached no consensus. When an agency transforms vague statutory language into a mandate affecting tens of millions of people, it is not exercising technical expertise. It is making a political choice — without political accountability.

The voters who disagree with that choice have no recourse. They cannot vote out the Assistant Secretary who signed the rule. They cannot primary the career attorney who drafted the guidance. The only remedy is litigation, which is expensive, slow, and uncertain. That is not democratic governance. That is administrative oligarchy with a democratic veneer.

What Congress Could Do — If It Had the Will

The REINS Act — the Regulations from the Executive in Need of Scrutiny Act — has been introduced in multiple congressional sessions. It would require Congress to affirmatively vote to approve any major new federal rule before it takes effect. The bill has passed the House multiple times and died in the Senate. Its logic is impeccable: if a regulation is important enough to reshape an industry or affect millions of lives, it is important enough to require a vote from elected representatives.

The major questions doctrine, as articulated by the current Supreme Court, provides some judicial guardrail. But courts are reactive institutions — they can only strike down overreach after it has already disrupted markets, burdened businesses, and imposed compliance costs that are never fully recovered.

The permanent fix is legislative discipline: Congress must stop writing laws so vague that agencies can drive entire policy agendas through the ambiguity. Specificity in legislation is not a technical inconvenience; it is the price of accountable government.

The Constitutional Stakes

The Founders were not naive about the temptation of executive power to expand into legislative space. The separation of powers was not an aesthetic preference — it was a structural firewall against the concentration of authority in unaccountable hands. When agencies write rules that carry the force of law, enforce them with civil penalties, and adjudicate violations through their own internal tribunals, they have collapsed that firewall into a single bureaucratic monolith.

Every rule issued without genuine congressional authorization is a small withdrawal from the account of democratic legitimacy. The account is not infinite.

A government that writes its own rules, enforces its own rules, and judges its own rules is not a constitutional republic — it is a bureaucracy with a flag.
