Lord Goff of Chieveley retired as Senior Law Lord on 1st September 1998. This collection of essays was specially commissioned to mark his Lordship's contribution to legal scholarship, not just from the bench, but as a teacher of law and as the co-author of a textbook on the Law of Restitution.Although a number of the essays naturally focus on unjust enric hment, Lord Goff's interests range far beyond that subject. Hence, there are contributions on criminal law, comparative law, contract, tort and private international law. The volume takes the opportunity to bring to a wider audience Lord Goff's influential 1983 Macabaean Lecture.
