It explains that intention can be direct or oblique and that recklessness may be defined as the conscious taking of an unjustified risk. It also explains how to distinguish between negligence and gross negligence. The chapter examines the concept of strict liability in the context of criminal law and discusses the implications of strict liability for actus reus and MR, evaluating arguments for and against strict liability, and considering the treatment of strict liability under the European Convention.
