The central purpose of this paper is to address the tension between legal and medical discourses within the coronial system. Medical expertise, based largely upon internal autopsy, becomes positioned as providing the more important information, rather than the legal model which focuses on evidence gathering at the scene. This paper will examine the aspects of the history, philosophy and consequences of the processes by which the medical model gained its current dominance and will conclude that, while autopsies are necessary, they are also over-used in the coronial system.
