Book excerpt: "[This book analyzes] the defences to criminal prosecutions both at common law and under statute in all jurisdictions of Australia. The various defences are described...together with the circumstances under which they can be raised and how several defences can be combined. The inter-relationship of the defences is also fully explored, with an eye to jurisdictional differences. It also includes additional analysis of Infanticide and Infancy as well as touching upon the Commonwealth Criminal Code."--
