Administrative rules and regulations, both federal and state, carry the force of law. They are promulgated under authority granted by statute to expand upon the general outline provided by the statute and to prescribe or prohibit activities in areas statutes do not reach. The federal compilation of administrative regulations currently in force is the Code of Federal Regulations (C.F.R.). The chronological compilation of new and amended regulations, both proposed and final, is the Federal Register (F.R.). Both the official C.F.R. and the Federal Register are available in PDF format online via FDsys, as well as in print on the third floor of the law library.
The official C.F.R. is published in multiple volumes that are re-issued annually. It is organized into titles that roughly correspond to the titles used to organize the United States Code. For example, Title 26 of the U.S.C. is the Internal Revenue Code, while Title 26 of C.F.R. contains Internal Revenue Service regulations. However, the correlation is not so precise for all titles. For example, Title 17 of the U.S.C. contains copyright statutes, while Title 17 of the C.F.R. contains securities regulations. The annual updating of the C.F.R. is done sequentially, with a portion of the entire set updated each quarter. The annual update cycle is as follows: titles 1-16 are revised as of January 1; titles 17-27 are revised as of April 1; titles 28-41 are revised as of July 1; and titles 42-50 are revised as of October 1. Check the front of each volume to determine when it was last updated.
The Federal Register is published every Monday through Friday except on federal holidays. It contains, among other items, the text of new and amended regulations, as well as proposed new regulations and amendments, and notices of repealed regulations.
To update a C.F.R. section:
If your section is not listed, there have been no changes during the period covered. If your section is listed, you will see a one or two word explanation of the change and a page number (which refers to a page in the Federal Register).
Note the date the most recent LSA pamphlet's coverage stops. There will always be a gap between that date and the day you are conducting your research. To fill the gap, you need to find:
NOTE: Publication of the LSA pamphlets has slowed markedly in the past few years. Therefore, updating in print sources can be cumbersome and time-consuming. We recommend that you use eCFR and the FDsys website, described below, or Bloomberg Law, Lexis, or Westlaw for updating.
Courts have a complex role in implementing and interpreting agency regulations. To determine whether judicial opinions have had an impact on the validity of a regulation, you should check a federal regulation on Shepard’s (Lexis) or KeyCite (Westlaw). Coverage differences between the two systems can result in quite distinct results, so this is an area where checking a citation in both systems is usually worth the slightly extra effort.
Bloomberg Law, Lexis and Westlaw provide the current full text of C.F.R. and the Federal Register. Both systems also contain superseded versions of C.F.R. back to the early 1980s in separate databases/sources. Federal Register coverage goes back to 1980 on Lexis and to its first publication in 1936 on Westlaw. On both systems, an alternative to searching the full text of C.F.R. and/or F.R. is to search the versions available in the specialized "area of practice" sources/databases. These contain only the titles pertinent to a particular area of law. As always with the specialty databases/sources, some caution must be used in deciding to search only in limited titles in order to avoid missing relevant material.
To search for a C.F.R. section online by subject, you can use either terms and connectors or plain language searching, using descriptive terms. Another approach, if you know the citation to the enabling statute, is to use the U.S. Code citation in a field/segment search as follows:
WestlawNext: cr(20 /5 4011) - searches the credit field
Lexis.com: authority(20 /5 4011) - searches the authority segment
The above examples will search your terms in only the portion of the document that contains the reference to the statute under which your regulation was promulgated. You can combine search terms with the field segment search if desired, using terms and connectors.
The online versions of C.F.R. are much more current than the print version, making updating an easier task. Each C.F.R. section online on either Lexis or Westlaw contains a line, near the heading, indicating the last issue of the Federal Register through which the section is updated. (Note: this does not mean that material affecting the section was published on that date in the Federal Register - merely that that is the last date through which the database has been updated.) The date of most recent update varies; it may be from a week or so to nearly a month prior to the date you are researching.
C.F.R. sections can be Shepardized on Lexis or KeyCited on Westlaw. Another alternative is to construct a terms and connectors search that uses the regulation cite as a search term.
The Government Printing Office site FDsys also provides search and updating capability for the C.F.R. and the Federal Register.
FDsys permits searching for regulations by citation or subject and includes the parallel authorities table in which cross references from U.S.C. citations to accompanying regulations in the C.F.R. may be found.
This web site has proven to be reliable and current, and is useful for updating regulations without incurring the costs associated with Lexis and Westlaw. To update a C.F.R. citation, Select the applicable List of CFR Sections Affected from FDsys. The List of CFR Sections Affected (LSA) is the tool researchers use to make sure they have the most recent changes to regulations and to find out whether there are any proposed amendments pending.
FDsys also offers access to the Electronic Code of Federal Regulations (e-CFR), , a much more current electronic version of the C.F.R. available at http://www.ecfr.gov/Although it is not an official edition of the CFR, is is an editorial compilation of CFR material and Federal Register amendments, so many researchers use the eCFR as an updating tool; the current update status is printed at the top of e-CFR pages.
Using this version makes it unnecessary to use the LSA to update regulations. However, Boolean searching is not yet possible in this version – you must browse by C.F.R. title and part.
Agency web sites may include statutes and regulations relating to the activities of the agency. Advantages of using an agency web site include the fact that they are free of charge and one need not know the precise citation to statutes and regulations in order to locate them. Be aware, however, that some such sites do not provide sufficient information as to the source or currency of the information provided.
