The essays in this collection examine the conceptual notions of property and obligations in law. Ideas of property and of obligations are central, organising concepts within law but are nevertheless liable to fragmentation and esoteric development when applied in particular contexts. In particular this collection focuses on the ways in which those concepts are applied to commercial law, land law, human rights law, intellectual property law, the law of restitution, company law and legal theory. This is a challenging and progressive collection of essays which cohere into an extensive examination of private law.
