Article analysing the decision of the Court of Appeal in Deutsche Morgan Grenfell v Commissioners of Inland Revenue  EWCA Civ 78. The piece argues that unjust enrichment claims involving public bodies cannot be regarded as belonging wholly in private law and that if the claim is based on a charge or payment that was invalid as a matter of public law, this public law illegality must also play a role in establishing the cause of action. Given the Court of Appeal's partial recognition of this fact in Deutsche Morgan Grenfell the article concludes that its decision is to be welcomed, but that in basing its decision on judgments in previous cases as if they were statutes the Court of Appeal lost an opportunity to examine the full implications and operation of this public law approach.
