Agency is a fundamental topic in commercial law, and a proper grasp of the subject aids the understanding of many other areas. The principles of the English law of agency are explored in this book through the case law from which they have developed. Contrasting views of other writers on the area are considered, alongside the authors own analysis of the cases. The nature of agency, and the rights and duties as between principal and agent, principal and third party, and agent and third party, are all examined in detail. The treatment is concise, but comprehensive. It should prove invaluable to those taking courses covering agency at undergraduate or postgraduate level, and to all who need a clear yet thorough treatment of this important subject.
