Dagan's book provides a dynamic and much needed account of the American law of restitution. The book reviews the existing doctrine, including the forthcoming (third) Restatement, using an ethical perspective to expose and critically examine the normative underpinnings of restitution's core categories. The author also discusses some of the most controversial issues in the area, such as cohabitation, improper tax payments, and the role of constructive trusts as trumps in bankruptcy. He argues that the concept of unjust enrichment is not an independent reason for restitution but, rather, serves as a loose framework, structuring the contextual application of commitments to autonomy, utility, and community in situations where either the cause of action or the measure of recovery is benefit-based. By integrating doctrinal and ethical analyses of restitution across the spectrum of restitution contexts, the author offers significant and provocative insights on existing law as well as possible reforms.
