The aim of this paper is to stress that an expert providing medico-legal opinion in matters relating to medical malpractice, workers compensation, transport accident and other injuries should preferably be a recognised expert in the field by virtue of knowledge, training, qualification and experience, free from bias as far as is possible and willing to provide evidence if called to court. Based on over ten years experience of conducting what is now largely a medicolegal practice and recently having obtained a Post Graduate Diploma in Health/Medical Law from Melbourne University and with approximately 800 assessments conducted yearly over that period, requirements for taking a comprehensive history, carrying out a thorough physical evaluation as well as assessment of all appropriate investigations and writing a “stand alone” medicolegal report will be outlined. Also included in the final opinion should be comments on opinions given by other experts. One should also include the summarised opinion in the world literature relating to the main issue. Finally, just as a judge does when giving his judgement the reasons underlying the opinion should be fully explained. Judges throughout Australia conducting medical lists are concerned that many medical assessments appear to be biased towards the party requesting and paying for the report; ways of reducing bias will be suggested. Finally the author will give his views on the value of expert medical panels independently appointed by the courts through the learned medical colleges giving their opinion on liability and whole person impairment in medical malpractice claims, and similar to medical panels currently assessing workers compensation injury in most states in Australia.
