This is the fifth, fully updated edition of Roy Goode's seminal work Commercial Law, covering the area's theoretical framework as well as its application. This classic work lays out both the theoretical framework of commercial law and the application of fundamental principles to typical business and financial transactions, explaining complex ideas with great clarity. With its unique combination of theory and practice, it is widely acclaimed by practising lawyers in many countries, and by law teachers and students, and it has been extensively cited in judicial decisions. This new fifth edition has been revised to bring the work completely up to date, incorporating a treatment of a significant number of leading cases in commercial law, as well as numerous important new developments affecting international commercial transactions.
