Defences in Unjust Enrichment, edited by Andrew Dyson, James Goudkamp and Frederick Wilmot-Smith, is the recently published second volume in an ongoing series, Hart Studies in Private Law: Essays on Defences. The first volume covered defenses in tort law, and the remaining two volumes will treat defenses in contract law and equity. The current volume offers essays by some of the world’s leading scholars, and a memorable note by Lord Reed of the Supreme Court of the United Kingdom. This is a welcome addition to unjust enrichment scholarship, as the study of defenses (and the change of position defense in particular) has been central to the development of this area of law in recent years.
