1. Administration and the principles of the constitution

Administrative law includes a complex variety of processes and doctrines that confer and control public power. This chapter outlines the underlying principles of administrative law. Topics discussed include the core principle of administrative law: opposition to arbitrary use of power. That principle is introduced through the story of habeas corpus from the middle ages to the twenty-first century. The constitutional principles of administrative law also include parliamentary sovereignty, the separation of powers, the rule of law, comity among constitutional authorities, accountability, and a newly emerging principle of open government. The chapter shows how the common law and legislation can achieve adherence to these principles of administrative law.
