LAWS5528 Unjust Enrichment and Restitution

(see Timetable)
Non-standard teaching periodUWA (Perth)Face to face
The law of unjust enrichment has until recently been the forgotten area of private law. It is now firmly entrenched as the third fundamental area of the law of obligations, along with contract and tort. This unit addresses the distinguishing features of this category of claim and its place in the broader private law comprising common law, equity and statute. It examines core areas of the law of unjust enrichment including mistaken payments, duress, failure of consideration and available defences such as change of position. It also critically analyses claims the nature of which have been highly contested, such as undue influence, unconscionable dealing, ‘no intention to benefit' and claims involving public authorities. In so doing, the unit will consider challenging and related concepts such as waiver of tort, tracing and the laws of estoppel. The unit also examines the law of restitution, the gains-based remedy for actions in unjust enrichment and an under-appreciated additional remedy available to other causes of action such as wrongs.
Students are able to (1) ) critically assess how restitutionary rights arise in unjust enrichment and how restitutionary rights are affected by defences;
; (2) ) integrate into their analysis of unjust enrichment principles their knowledge of contract, property, torts, trusts and other common law, equitable and statutory concepts and principles, to identify inconsistencies and gaps in the developing law of unjust enrichment; (3) critically assess the legal frameworks applicable to unjust enrichment and restitution law across Australian and overseas jurisdictions, as relevant;
; (4) identify opportunities for judicial and legislative reform of aspects of the Australian approaches in light of those comparisons;
; (5) engage in self-directed legal research to create an autonomous piece of original legal writing on a relevant topic for the unit and
; and (6) communicate clearly in written form an integrated understanding of the complex legal principles, theories and frameworks concerning unjust enrichment law and its relationship to the private law as a whole..
Indicative assessments in this unit are as follows: (1) case analysis and (2) mid semester exam. Further information is available in the unit outline.

Supplementary assessment is not available in this unit.
