AS Law is written specially for students taking AS Law in its own right, or as the first part of the A-level course. This expanded and updated fourth edition builds upon the success of earlier editions in providing a highly readable text on the English legal system and the principles of crime and negligence as basic concepts of liability. The book covers the requirements of both AQA and OCR specifications. This fourth edition contains additional material updating the text in the light of recent changes and developments in both the law and the English legal system, and in response to specification amendments. It includes a section of examination type questions and answers, activities and guidance on key skills coverage, and a number of new diagrams and illustrations.
