Steps to Updating the Code of Federal Regulations in Print

Listed below are the steps in updating a federal regulation to determine if it has been amended, repealed, or superseded. For this example, we will update 21 C.F.R. § 201.25.

  1. Examine the regulation in the most current Code of Federal Regulations (CFR) volume. Note the date of revision on the front cover.

                             

  1. Consult the most recent monthly List of CFR Sections Affected (LSA) pamphlet to see if your section is listed. If there has been a change, there will be a reference to page numbers in the Federal Register. You will need to cover the time period from step (1) to the most recent LSA pamphlet. Note that December, March, June, and September issues cumulate changes for one entire year for particular titles, so you should only have to check a few pamphlets.

    This is the January 2011 LSA. Note that we received it on March 18, 2011.

    Recall that Title 21 of the CFR was current to April 1, 2010. The January 2011 LSA reflects changes to Title 21 of the CFR from April 1, 2010 through January 31, 2011.

    There were no changes to 21 C.F.R. § 201.25 between April 1, 2010 and January 31, 2011.

    If there were changes to the regulation, there will be references to page numbers in the Federal Register where the changes could be found.

  2. Consult the last issue of the month of the Federal Register for each complete month since the month on the cover of the most recent LSA pamphlet. Check the CFR PARTS AFFECTED DURING [month] table near the back of the issue. Do not make the mistake of consulting the CFR PARTS AFFECTED IN THIS ISSUE table located near the front of each Federal Register issue.

    This covers any changes to Title 21 of the CFR from February 1, 2011 to February 28, 2011. February 28, 2011 is the last issue for the month of February 2011.

    There were no changes to 21 C.F.R. § 201.25 during the month of Febrary 2011. If there were changes to the regulation, there will be references to page numbers in the Federal Register where the changes could be found. This table is cumulative throughout the month, so the further along in the month the larger the table. This is a reference to the page number in one of the February 2011 Federal Registers where the changes were published affecting 21 C.F.R. pt. 573.

  3. Finally, consult the most recent issue of the Federal Register available and check the CFR PARTS AFFECTED DURING [month] table, located at the end of the issue.

    This is the latest issue available for the month of March 2011.

    This cumulative table indicates that 21 C.F.R. pt. 201 was amended and this can be found on page 12,847 of the Federal Register. We also know that this was published sometime in March 2011 because this table is cumulative for the month.
