The fourth edition of Concise Australian Commercial Law has been updated to incorporate the legislative amendments and case law developments since the last edition. The updates and amendments to each chapter include the following: An Introduction to Studying Law includes a re-worked guide on how to approach business law and, in particular, how to approach the various forms of assessment. There are a number of worked examples of typical hypothetical problems, advice on how to approach research assignments and multiple-choice questions. The chapter on the Australian Legal System has been simplified so as to make it more accessible for the non-law student. In the Contract Law chapters, reflecting the changed legal and commercial environment, there are new sections on online contracting and the regulation of electronic transactions. These chapters also incorporate a number of recent decisions including the High Court's decisions in Paciocco v Australia and New Zealand Banking Group Ltd (2016) on penalties and Crown Melbourne Ltd v Cosmopolitan Hotel (2016) on unconscionable conduct and collateral contracts.
