SELT Survey Results

The course covers aspects of the law of restitution as it has developed in Australia, England and (to a lesser extent) Canada, and considers the inter-relationship between restitution, contract, equity, and other categories of legal obligations.

The course considers the relevant law from three perspectives: historical, conceptual and doctrinal.  It provides a useful overview of the private law of obligations and property.  The first section of the course considers:

  • the history of restitution; and
  • theories of restitution and the concept of unjust enrichment

The second part of the course examines various situations where restitutionary relief may be sought including:

  • mistake (including its role as the paradigm unjust enrighment claim);
  • ineffective contracts;
  • restitution after breach of contract;
  • compulsion;
  • restitution for wrongs;
  • property and restitution;
  • equity and restitution; and
  • other topical issues.

Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

  1. Explain and apply to a complex hypothetical factual problem the law relating to selected topics taught in the course;
  2. Demonstrate an advanced and general understanding of the theoretical debates concerning the structure, content and methodology of the law of Restitution;
  3. Conduct research with some independence to critically evaluate the theoretical debates concerning the structure, content and methodology of the law of Restitution;
  4. Demonstrate an understanding of the relationship of the law of Restitution to other categories of the law of obligations and to Equity, and to synthesise knowledge in these areas of law.

Research-Led Teaching

Pauline Ridge researches in equity, restitution and contract law. Her research in these areas informs the teaching of this course.

Required Resources

ANU has educational policies, procedures and guidelines, which are designed to ensure that staff and students are aware of the University’s academic standards, and implement them. Students are expected to have read the Academic Misconduct Rule before the commencement of their course. Other key policies and guidelines include:

Assessment Requirements

The ANU is using Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. For additional information regarding Turnitin please visit the ANU Online website. In rare cases where online submission using Turnitin software is not technically possible; or where not using Turnitin software has been justified by the Course Convener and approved by the Associate Dean (Education) on the basis of the teaching model being employed; students shall submit assessment online via ‘Wattle’ outside of Turnitin, or failing that in hard copy, or through a combination of submission methods as approved by the Associate Dean (Education). The submission method is detailed below.

Moderation of Assessment

Marks that are allocated during Semester are to be considered provisional until formalised by the College examiners meeting at the end of each Semester. If appropriate, some moderation of marks might be applied prior to final results being released.


The workload expectation for each six-unit course at the ANU is 10 hours per week

Weighting: 20% in total. Each task is worth 5% of your overall course result.

Release: On the course Wattle site at 6pm, Wednesday in Weeks 3, 7, 9 and 11. Once a task is opened, it must be completed within one hour.

Due date: 6pm, Thursday in Weeks 3, 7, 9 and 11 (that is, each task will be accessible for 24 hours). If you experience unavoidable and extenuating circumstances and cannot sit the quiz at the due date and time, you should apply for an extension to the College of Law student admin team here:

Academic Integrity

Academic integrity is a core part of the ANU culture as a community of scholars. At its heart, academic integrity is about behaving ethically, committing to honest and responsible scholarly practice and upholding these values with respect and fairness.

The Academic Misconduct Rule is in place to promote academic integrity and manage academic misconduct. Very minor breaches of the academic integrity principle may result in a reduction of marks of up to 10% of the total marks available for the assessment. The ANU offers a number of online and in person services to assist students with their assignments, examinations, and other learning activities. Visit the Academic Skills website for more information about academic integrity, your responsibilities and for assistance with your assignments, writing skills and study.
