Despite recent attempts at judicial reformulation, the question of the effect of a plaintiffs illegal conduct on his right to pursue a common law negligence action for personal injury damages remains largely unsettled, and on an uncertain policy and doctrinal foundation. There is a continued obsession with public policy, whether expressed, as it is in England, as a matter of public conscience, or in Australia, as a proximity consideration preventing the finding of a duty of care. However formulated, public policy, in particular the public conscience, as an ad hoc means of determining the effect of a plaintiff's illegality, is unsatisfactory for this purpose, and has proved problematic and unmanageable for the courts. It is here submitted that personal injury negligence law, properly understood and deployed, does not require, nor is served by, the continued application of the illegality defence.
