Administrative procedure is often perceived as a nuisance by those involved: by individuals seeking an action, service or permission from the state as well as by members of the administration wanting to pursue an action against an individual or refusing to act in her favour. Both sides may view administrative procedure as an unwelcome hurdle on their way to reach their objectives. This perception, however, clouds the value and importance of administrative procedure for the individual in modern legal systems. It is not an end in itself but protects individuals against arbitrary state action.This book explores the connection between international human rights law and administrative procedure. In particular, it discusses potential justifications for obligations of administrative procedure under international human rights law, their doctrinal construction, and their implementation as well as the scope of review of courts.
