"The chapters in this book were originally presented at the Ninth Biennial Conference on the Law of Obligations, which was co-hosted by Melbourne Law School and the Faculty of Law at the University of Oxford and held in Melbourne in July 2018. They explore the relationship between form and substance in the law of obligations. The volume builds on the rich tradition of legal thought that deploys these concepts to inform our understanding of the common law. The essays offer multiple conceptions of form and substance and cover an array of private law subjects, scholarly approaches and jurisdictions. The collection makes it clear that the interplay between form and substance is a key element of the dynamism that characterises this area of the law".
