In this acclaimed new work the author argues that it should be the function of company law to promote the public interest. Examining a number of topical and controversial issues from that perspective, including the adequacy of corporate governance arrangements, the 'Nexus of Contracts' theory of the company, and the role of markets, the author explains why the theory of company law has to be understood in order for the day-to-day practice of company lawyers to be fully appreciated. The book explores in some depth the protection of interests largely ignored by company law, such as those of employees and the local community, and the safeguarding of the environment from corporate abuse.
