This project examines federal administrative adjudication that is not subject to the adjudicatory provisions of the Administrative Procedure Act (i.e., non-APA adjudication) and takes the form of a sourcebook for agencies, Congress, the federal judiciary, and the public. It draws on the Federal Administrative Adjudication project and database and builds on the Evidentiary Hearings Not Required by the Administrative Procedure Act project. It provides a comprehensive overview and cross-cutting analysis of non-APA adjudication. It examines, among other things, the structure of the initial adjudication and any appeals; pre-hearing, hearing, and post-hearing procedures; the types of adjudicators used; and the case loads at individual agencies. It relies in part on case studies to flesh out the overarching findings.
