There has recently been a proliferation of case law dealing with potential inroads into the presumption of innocence in the criminal law of England and Wales, in the light of article 6(2) of the European Convention on Human Rights. This article is concerned with the nature of the presumption of innocence. It considers two central issues. The first is how the courts should address the question of when the presumption of innocence is interfered with. The second is the extent to which interference with the presumption of innocence may be justified on the grounds of proportionality. It is argued that the courts have not developed the appropriate concepts and principles properly to address these questions.
