This part of the book includes the hypothetical cases and the answers given by the experts of the various legal systems included in this volume's comparison. This is the core of the volume's ‘factual analysis'. The authors thus suppose that administrative functions and powers are exercised by public authority in a certain way and raise issues concerning the standards of administrative conduct and the mechanisms for controlling it and making public bodies accountable. Considered as a whole, the hypothetical cases concern three type of constraints on administrative rulemaking and planning: parliamentary oversight and judicial review; consultation; and general principles, such as legitimate expectations and transparency. As in the previous books of this series, the disaggregation of these responses is designed to facilitate the analytical process. Their common and distinctive traits will be examined in Part IV.
