39 C.F.R. § 2.6
The invalidity of any provision of these bylaws does not affect the validity of the remaining provisions, and for this purpose these bylaws are severable. The Board may amend or repeal these bylaws at any special or regular meeting, provided that each member of the Board has received a written notice containing a statement of the proposed amendment or repeal at least five (5) business days before the meeting. The members of the Board may waive the five (5) business days' notice or the operation of any other provision of these bylaws by unanimous consent, if that action is not prohibited by law. The Secretary shall submit the text of any amendment to these bylaws for publication in the FEDERAL REGISTER as soon as practicable after the amendment is adopted by the Board.
