Douglas and Jones is well established as a leading text on administrative law, a reliable book notable for its accessibility and contemporary perspective. The 8th edition, in which Roger Douglas is joined in authorship by Professor Michael Head, Yee-Fui Ng and Margaret Hyland, will maintain the reputation of its predecessors. It has been fully updated to take account of tribunal amalgamations, Freedom of Information developments and a range of significant High Court decisions, including on unreasonableness, procedural fairness, bias and jurisdictional error.
