Citing Federal Regulations

From the Georgetown Law Library's Bluebook Guide.

Rule 14 covers how to cite administrative and executive materials, including U.S. federal regulations. 

A citation to a U.S. federal regulation in the Code of Federal Regulations (C.F.R.) includes four elements:

  1. C.F.R. title number
  2. C.F.R. (The Bluebook's abbreviation for the Code of Federal Regulations)
  3. Section symbol and specific section cited
  4. Date of code edition cited

For example, here is how you would cite a federal regulation that prescribes rules for pets in National Parks in the United States:

36 C.F.R. § 2.15 (2017)

For state regulations, follow the citation format provided for the state in Table 1.
