This is the first major update to the 18th edition of Arnould on The Law of Marine Insurance and Average, bringing the work fully up to date as of 1 October 2015. This Supplement is divided into two parts. Part 1 is a special supplement containing a detailed analysis of the Insurance Act 2015. The stand-alone analysis of the 2015 Act is set out in six chapters in Part 1: Covering the development of the Act. Analysing the new regime concerning non-disclosure and misrepresentation in non consumer insurance contracts (reclassified as the duty of fair presentation). Analysing the new regime governing warranties and certain kinds of "other terms". Dealing with fraudulent claims and the "interpretive principle" of utmost good faith retained in the 2015 Act. Explaining the contracting out provisions in the new regime. Discussing the amendments to the Third Parties (Rights against Insurers) Act 2010 in Part 6 of the 2015 Act. The second part of the Supplement concentrates on the existing law. To avoid undue repetition, references to the forthcoming changes under the 2015 Act are generally omitted from Part 2 which updates the 18th edition in a more conventional way and is to be read side by side with the 18th edition. In some instances the text of the 18th edition is modified or extended and in other cases it's completely superseded. The material covered in Part 2 includes: The effect of the Consumer Rights Act 2015 The Counter-Terrorism and Security Act 2015 The implementation of the Financial Services Act 2012 and Solvency II.
