The Key Cases series is designed to give a clear understanding of important cases. This is useful when studying a new topic and invaluable as a revision aid. Each case is broken down into fact and law. In addition many cases are extended by the use of important extracts from the judgment or by comment or by highlighting problems. In some instances students are reminded that there is a link to other cases or material. If the link case is in another part of the same Key Cases book, the reference will be clearly shown. Some links will be to additional cases or materials that do not feature in.
