This subpart provides guidance to agencies on compliance with section 15 of the Act. Section 15 establishes requirements that apply only in connection with a funding or other written agreement involving an agency's use of advice or recommendations provided to the agency by the National Academy of Sciences (NAS) or the National Academy of Public Administration (NAPA), if such advice or recommendations were developed by use of a committee created by either academy. For purposes of this subpart, NAS also includes the National Academy of Engineering, the Institute of Medicine, and the National Research Council. Except with respect to NAS committees that were the subject of judicial actions filed before December 17, 1997, no part of the Act other than section 15 applies to any committee created by NAS or NAPA.
