Subscribers to Private Law Theory will have seen that Andy Burrows has published “In Defence of Unjust Enrichment” in the Cambridge Law Journal.

The paper aims to defend the view that unjust enrichment is a single cause of action rather than a collection of multiple liability principles.

More circumspect is a speech of Hon. Susan Glazebrook of the NZSC, entitled “Unjust enrichment: the platypus of private law”, delivered in 2018, which can be found here:  https://www.courtsofnz.govt.nz/publications/speeches-and-papers 

You need to scroll down a bit. I did not include the direct link because, at least on my browser, it downloads the speech and I did not think it was polite to put such a link directly in a posting.

Happy Thanksgiving to Canadian list members,
