For instructions on how to cite to a federal regulation generally, see Rule B14 and Rule 14.2 of The Bluebook: A Uniform System of Citation.
In its simplest form, the correct citation for a federal regulation has two basic parts:
Whenever available, cite federal regulations to the Code of Federal Regulations (C.F.R.).
We will use the two examples below to explain how to cite to federal regulations in the C.F.R.
29 C.F.R. pt. 1980 (2021).
29 C.F.R. § 1980.103 (2021).
1. Published Source in Which the Regulation May Be Found
The published source in which the regulation may be found is broken down into three parts:
2. Date of Code Edition Cited
The Code of Federal Regulations (CFR) is published in 50 subject matter titles on a as follows: Titles 1-16 are revised as of January 1st, titles 17-27 are revised as of April 1st, titles 28-41 are revised as of July 1st, and titles 42-50 are revised as of October 1st. You should cite to the most recent edition of the C.F.R. For our examples, part 1980 of Title 29 of the CFR was revised on July 1, 2021, so we will use 2021 for the date in our citations.
Example 1: 29 C.F.R. pt. 1980 (2021). 29 is the Title of the C.F.R. "pt." is the abbreviation for "part". 1980 is the numerical designation for the part. 2021 is the date of publication of the regulation being cited.
Example 2: 29 C.F.R. § 1980.103 (2021). 29 is the Title of the C.F.R. 1980 is the numerical designation for the part. 103 is the section within the part that is being cited. Section numbers are set apart from part numbers by decimal points. When a specific section is being cited, instead of an entire part, the abbreviation for part is not used, but a section symbol is used before the part-section number. 2021 is the date of publication of the regulation being cited.
Every free-standing citation has a period at the end.
Sometimes, you may need to cite to the Federal Register, which publishes rules and regulations before they are published in their finalized form in the Code of Federal Regulations. Proposed rules, meeting notices, and guidance materials such as policy interpretations are also published in the Federal Register, using the same format.
A proper citation to the Federal Register should include:
For a publication of final rules in the Federal Register, you must also include the place where it is to be codified in the Code of Federal Regulations, if it is indicated.
Rule 14.2 of The Bluebook has more on how to cite to the Federal Register.
A citation to a regulation published in the Federal Register can be broken out into several components. In the following example, the complete citation is written as:
Amendment to Incorporation by Reference in Safety Standard for High Chairs, 87 Fed. Reg. 42636, July 18, 2022 (to be codified at 16 CFR §1231.2).
The commonly used name of the regulation is: Amendment to Incorporation by Reference in Safety Standard for High Chairs. A comma is used after the name of the regulation, to separate it from the regulation's location in the Federal Register.
87 is the volume of the Federal Register (abbreviated Fed. Reg. ) containing the regulation, and 42636 is the page number within the volume where the regulation begins.
July 18, 2022 is the date of the regulation's final publication in the Federal Register. 16 C.F.R. §1231.2 is the place where the regulation is published in the Code of Federal Regulations. This citation references a specific section within Title 16 related to Consumer Product Safety.
Every free-standing citation includes a period at the end.
