Unjust enrichment as the basis of Restitution — an overworked concept
The proposition that ‘Restitution is based on unjust enrichment’ is usually the first that a student of Restitution is presented with. It is a claim at several different levels: as to the terminology we should use in discussing Restitution; as to the sort of rules the subject contains; and as to the way these rules have been developing or should develop in the future. Nor is this confusion of claims particularly surprising. Much of the work of the academic lawyer consists of interpreting the judgements of the higher courts; it is not really very odd when those courts’ ambivalent approach to whether they are making the law, or simply applying it, rubs off. ‘Restitution is based on unjust enrichment’ is really a collection of subsidiary propositions about Restitution; and it is clear that, of those who believe that Restitution is so based, not all would subscribe to every one of the subsidiary propositions.
