Cited regularly by superior courts in every jurisdiction in Australia and New Zealand, this work analyses the complex law and practice surrounding expert witnesses and expert evidence in personal injury, commercial, criminal and family law litigation. Setting out and interpreting the complex common law and statutory criteria for expert evidence admissibility, the book also provides guidance regarding expert witness appearances. Fundamentally revised to accommodate the increasing application of the uniform evidence legislation, this 4th edition also deals with a wide range of new areas of specialist evidence. It analyses relevant court rules and the use of single experts and concurrent evidence by experts (hot-tubbing) and incorporates new analysis of the law concerning expert witness immunity, civil and disciplinary actions against experts and evidence in relation to psychiatric injuries.
