where does a law that is cited as 47 cfr 300 come from
Law of the United States Regulations are adopted pursuant to the Administrative Procedure Act (APA). Regulations are first proposed and published in the Federal Register (FR or Fed. Reg.) and subject to a public comment period. Eventually, after a period for public comment and revisions based on comments received, a final version is published in the Federal Register. The regulations are codified and incorporated into the Code of Federal Regulations (CFR) which is published once a year on a rolling schedule.
