This second edition draws together the UK law relating to fiduciary duties and analyzes both its historical origins and its modern application by the courts. Fiduciary duties have historically defied easy characterization. This area of law as it relates to the UK's directors and employees is developing and complex. Directors and employees of companies acting out of self-interest have generated an increasing number of claims alleging breach of fiduciary duty. The law relating to the fiduciary duties owed by directors and employees to companies is complex and involves several overlapping areas of law. It is, however, a relatively commonplace cause of action - individuals in positions of trust within a company are often tempted to abuse their position in order to steal company secrets, set up in competition, and poach staff and customers. The book contains commentary on a number of new UK cases, alongside further commentary and analysis on the developing jurisprudence in relation to the fiduciary duties of LLP members and joint ventures. In addition, discussion is conducted regarding the Court of Appeal decisions relating to Bolkiah information barriers in an employment context, together with evaluation of the relevant Commonwealth jurisprudence as it bears upon issues also arising under English law. As a result, this new edition will be an essential research reference for anyone practicing in this area of the law.
