Book excerpt: THE INTERPRETATION OF CONTRACTS IN AUSTRALIA provides practitioners with essential guidance on the construction and interpretation of contracts, including in difficult matters of disputed interpretation. This adaptation of the widely acclaimed English title THE INTERPRETATION OF CONTRACTS by Sir Kim Lewison has been long awaited. Former Chief Justice Spigelman of the Supreme Court of NSW writes in the Foreword to this work. Now barrister David Hughes and Sir Kim Lewison have thoroughly revised the English text to reflect Australian law, while retaining the structure and principles of interpretation of the first nine chapters of the English edition. These principles of construction and interpretation are discussed in chapters which proceed through the key rules governing each of them. Extracts and summaries of decisions are provided to illustrate the application of those rules. The text's insights will inform the process of drafting or revising a contract by identifying key principles and discussing them comprehensively, yet concisely, with reference to case law. By enabling lawyers to construct arguments rooted in the case law, this new Australian work will help lawyers better challenge contracts and explain their inadequacies.
