Congress writes the outline; agencies write the details, in a public process anyone can join. Most binding federal law by volume is made exactly this way.
When Congress says 'workplaces shall be safe' or 'drinking water shall be clean', someone must decide what counts. That someone is an agency, and the how is rulemakingThe legal process agencies must follow to issue binding regulations: publish a proposal, take public comment, respond, then publish a final rule.Full definition in the glossary: a legally mandatory cycle of proposal, public comment, and reasoned response set by the Administrative Procedure ActThe 1946 law that sets the ground rules for agency action: how rules are made, how hearings run, and when courts can strike agency decisions.Full definition in the glossary of 1946. It is the most participatory lawmaking the federal government has, every comment filed becomes part of a record the agency must answer and courts can unanimous consentDoing business by universal agreement instead of votes. Most Senate floor action happens this way, which is why a single objecting senator has real power.Full definition in the glossary it to.
Every rule starts with an enabling statute in which Congress sets the goal and hands an agency the details. The delegation defines the rule's outer boundary: an agency can only regulate what its statute covers, and courts, especially under the major-questions doctrine, enforce that boundary with growing strictness.
Agency staff, engineers, economists, lawyers, draft the rulemakingThe legal process agencies must follow to issue binding regulations: publish a proposal, take public comment, respond, then publish a final rule.Full definition in the glossary and its supporting analysis. Economically significant rules then pass through OIRA, the White House's regulatory review office, which coordinates across agencies and weighs costs and benefits before anything publishes.
This review layer runs on executive orders (E.O. 12866 is the backbone), which is one concrete way presidential priorities steer the regulatory state.
The Notice of Proposed Rulemaking (NPRM) appears in the Federal RegisterThe federal government's daily journal, publishing executive orders, proposed and final rules, and official notices since 1936.Full definition in the glossary: the proposed text, the legal authority claimed, the reasoning, and a deadline for comments. From this moment the process is on the public record.

Companies, states, advocacy groups, experts, and ordinary citizens file comments, typically for 30 to 60 days, all public. This is not a poll: a single comment identifying a real flaw in the agency's data or reasoning outweighs ten thousand form letters, because the agency must answer substance, not count heads.

The agency publishes the final rule with a preamble responding to the significant comments and explaining every choice, the reasoned explanation courts will later review. Most rules must wait at least 30 days before taking effect; major ones wait 60.
New rules are submitted to Congress, which has roughly 60 legislative days to pass a joint resolutionA measure (H.J.Res. or S.J.Res.) that travels the same path as a bill and has the same force of law. Also the only vehicle for proposing a constitutional amendment.Full definition in the glossary of disapproval, filibusterExtended debate used to block a Senate vote. Because most measures need 60 votes to cut off debate, a determined minority can stop legislation that has majority support.Full definition in the glossary-proof in the Senate. If the President signs it (or a veto is overridden), the rule dies and the agency is barred from issuing a substantially similar one without new law.

Anyone injured by a rule can sue. Courts set rules aside when they exceed the statute, skipped required procedure, or are 'Administrative Procedure ActThe 1946 law that sets the ground rules for agency action: how rules are made, how hearings run, and when courts can strike agency decisions.Full definition in the glossary', meaning the agency failed to reason from the record it built. The comment file assembled in stage 4 is exactly what the court reads.
Surviving rules are codified by subject into the CFR, the regulatory mirror of the public lawWhat a bill becomes when enacted, numbered by Congress and order of enactment: Public Law 119-4 is the 4th law of the 119th Congress.Full definition in the glossary, and enforced through the agency's inspection, licensing, and penalty machinery. Amending or repealing a rule requires the same notice-and-comment process that made it, the door swings both ways, at the same deliberate speed.
