LLB courses in universities (Foundation subject) and CPE/Diploma courses (core subject). University of London (External) LLB. ILEX courses (para-legals).Postgraduate LLMs in contract law. This major new textbook on contract law is arranged around a transactional analysis. This brings into clearer focus two important episodes in the life of a contract - the negotiation phase and the modification phase. These two episodes are either neglected or examined in a piecemeal way by traditional doctrinally arranged texts. Throughout the book the transactional approach is informed by contextual, empirical and theoretical writing. It also discusses in depth other parts of the law of obligations (e.g. restitution, tort and estoppel) where they impinge on its subject. Overall, this is an original, challenging, academically oriented but also practically satisfying text for modern contract courses, reflecting modern economic reality.
