This open access book considers the consequences that arise from the different degrees of codification of general administrative law. It answers 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, a chapter on the EU, and a comparative analysis.
