ACUS "is an independent federal agency within the executive branch whose statutory mission is to identify ways to improve the procedures by which federal agencies protect the public interest and determine the rights, privileges, and obligations of private persons."
ACUS and the American Bar Association’s Section of Administrative Law and Regulatory Practice publish the
Federal Administrative Procedure Sourcebook, "an annotated compilation of the key legal sources governing nearly every aspect of administrative procedure. It provides an overview of the major laws governing administrative procedure and offers access to statutory text, legislative history, agency regulations, guidance documents, law review articles, and other sources of relevant information."
