Book excerpt: Mastering Administrative Law is designed as a supplement to law school courses in Administrative Law or as an introduction to the subject for lawyers trained in other legal systems. The book explicitly and in plain language identifies the functions of the various principles of administrative law. It covers all the basic administrative law topics, including how the administrative process fits into our governmental structure, typical agency procedures (e.g., rulemaking, adjudication, investigation, etc.), important statutes affecting agencies (e.g., the freedom of information act), constitutional limits on legislatures and agencies and the limited but critical role of the courts in helping monitor the process. A number of classroom-tested graphics--charts, tables, diagrams--supplemented this text by identifying essential doctrinal components and illustrating important doctrinal relationships.
