Observing the general principles of the subject and structure and formation of insurance contracts, this text goes on to look at individual considerations in detail, including the duty of utmost good faith/fair presentation of the risk, insurable interest, terms of insurance contracts, warranties and conditions, brokers, the premium, causation and marine perils, losses, sue and labour, subrogation, fraudulent claims, and reinsurance. The third edition has been fully updated and expanded to cover additional pre-Marine Insurance Act 1906 (MIA 1906) cases, as well as the implications of the Insurance Act 2015 on the duty of fair presentation of the risk in business insurance and on the remedy for breach of a warranty. The reader will also read about the emphasis placed by the UK Supreme Court on the construction of s. 55 of the MIA 1906, and the challenges faced in respect of claims for a constructive total loss of the subject matter insured, which are especially current at the time the book is being prepared for its publication. This textbook is the ideal companion for any student, academic, and practitioner wishing to study the subject and to explore more detailed information on the principles of marine insurance law.
