The varieties of subrogation
By means of the doctrine of subrogation, one person is substituted for another in the exercise of that other’s rights against a third person. In particular, it is the process by which one party is substituted for another so that the first party may enforce that other’s rights against a third party. Mark Leeming (Faculty of Law, University of Sydney) has just published “Subrogation, Equity and Unjust Enrichment” as Sydney Law School Research Paper No 12/52 on SSRN. It is a version of his paper in Glister and Ridge (eds) Fault Lines in Equity (Hart Publishing, Oxford, 2012) 27-43 (collecting the papers from the symposium “Comparative Perspectives on Equity” held at the University of Sydney on 14 December 2010). This is the abstract:
…Is “unjust enrichment” merely a unifying theme, or is it something more, a legal norm in its own right capable of supplying answers to particular cases? Or, if that is a false distinction, and indeed “unjust enrichment” may be either, then what approach is more likely to result in a legal system whose operation is clear, certain and coherent? This paper is directed to those questions. It notes the highly divergent approaches to a single doctrine – subrogation – in the House of Lords and the High Court of Australia, with a view to evaluating which mode of reasoning leads to clarity, transparency and coherence.
