Concise Australian Commercial Law, now in its fifth edition, has two basic objectives: to provide students with a general understanding of the legal environment of business and to expose them to the language and perspectives of legal professionals, regulators and other commercial actors; and to provide a reference point for non-law students studying key commercial law topics - the law of contract, torts, consumer protection, agency, business organisations and business ethics - in a way that is clear, accessible and challenging for a non-law student. The authors have selected cases that should be of interest to non-law students and every effort has been made to ensure that the case extracts contain sufficient information to enable students to discuss and debate the decisions that a court has reached and appreciate how the principles could be applied in a commercial environment. Similarly the relevant legislation is discussed in a way that is designed to promote understanding of the law and the policy considerations behind the legislation. The fifth edition been updated to incorporate the many legislative changes and case law developments since the last edition. These updates include: a revised introduction (including a guide on how to approach the study of commercial law); a number of new contract law cases and an expanded section on online contracting; amendments to the Australian Consumer Law as well as a number of interesting new cases concerning consumer protection; case law developments in relation to the standard of care and causation in negligence; the recent 'safe harbour' amendments to the Corporations Act and a number of new cases dealing with directors' duties: and revisions to the chapter on Business Ethics to include references to the Royal Commission into Misconduct in the Banking, Superannuation and Financial Services Industry (the Banking Royal Commission). To ensure the text is a more complete teaching and learning package, there is a revised set of activities at the end of each chapter that have been written with the non-law student in mind and can readily be used in a student-centred group work environment.
