This open access book presents the first comparative study on the legal sources of administrative law. Every modern legal order needs a set of general rules to apply and enforce administrative law
the rules impose principles of action, of procedure, and of organisation of the authorities. The legal basis of these rules may be quite diverse. Some countries have tried to codify administrative law, whilst others work with few rules or unwritten rules. The book considers the consequences that arise from the different degrees of codification of general administrative law. It presents answers to important questions including: Does codification increase predictability and legal certainty? Does codification lead to a 'petrification' of administrative law? To what degree does the constitution shape administrative law? Which areas of administrative law are suitable for codification, which are not, and why not? The book answers these questions by presenting 13 country reports, covering both civil and common law traditions, a chapter on the EU, and a comparative analysis. This book is available as open access through the Bloomsbury Open Access programme and is available on www.bloomsburycollections.com.
