44 U.S.C. § 1507 : US Code - Section 1507: Filing document as constructive notice; publication in Federal Register as presumption of validity; judicial notice; citation

      A document required by section 1505(a) of this title to be
    published in the Federal Register is not valid as against a person
    who has not had actual knowledge of it until the duplicate
    originals or certified copies of the document have been filed with
    the Office of the Federal Register and a copy made available for
    public inspection as provided by section 1503 of this title. Unless
    otherwise specifically provided by statute, filing of a document,
    required or authorized to be published by section 1505 of this
    title, except in cases where notice by publication is insufficient
    in law, is sufficient to give notice of the contents of the
    document to a person subject to or affected by it. The publication
    in the Federal Register of a document creates a rebuttable
    presumption - 
        (1) that it was duly issued, prescribed, or promulgated;
        (2) that it was filed with the Office of the Federal Register
      and made available for public inspection at the day and hour
      stated in the printed notation;
        (3) that the copy contained in the Federal Register is a true
      copy of the original; and
        (4) that all requirements of this chapter and the regulations
      prescribed under it relative to the document have been complied
      with.

      The contents of the Federal Register shall be judicially noticed
    and without prejudice to any other mode of citation, may be cited
    by volume and page number.
