The article is a critique of Ernest Weinrib’s attempts to explain the structure of unjust enrichment law according to his theory of corrective justice. The plausibility of Weinrib’s account of unjust enrichment is of critical importance to his claim that corrective justice is a theory of private law in general. Ultimately, I argue that Weinrib’s efforts to accommodate unjust enrichment within his conception of corrective justice fail. This is in large part due to the fact that Weinrib sets himself the uphill task of both explaining unjust enrichment from its own internal perspective where the structure of liability is strict and not based on fault and justifying it in terms of his interpretation of corrective justice which is rooted in wrongdoing. The dilemma between structure and justification runs throughout Weinrib’s early and recent writings on unjust enrichment, and I argue that there is now a need to confront it.
