Thanks Paul.

 

With English eyes and a vague understanding of how other common law systems deal with these situations, one can somewhat see it might be similar to the many farm "proprietary estoppel" (sic) cases we have here: party A agrees to work for party B for free or reduced compensation for a long period in expectation of receiving a substantial reward later in life.

 

In cases not involving contract, then the standard position would be that if the agreed counter-performance (i.e. the expected eventual reward) fails, then A ought to get back the market value of the work put in at that stage. But if the parties have a contract, then the contract will be important in deciding what the condition of the performance was, and the consequences of it failing. As I argued in a recent English CA case, that isn't "exclusion", that is a prior stage of the analysis of the cause of action.

 

I don't think the fact that the parties have a contract automatically "excludes" a claim in restitution, any more than a contract excludes it the standard commercial case involving a failure of counterperformance. Exclusion of an existing right would normally have to be spelled out specifically, whether expressly or by necessary implication.

 

Of course, none of the above is how the English courts actually deal with these farm cases, and obviously English law on failure of condition is no sensible read across to Quebec civil law!

 

Best,

 

Matthew

I believe -- my grasp of French is better than my grasp of unjust enrichment -- the theory of the case was that the lower earning spouse and the higher earning spouse undertook a common project to support the latter's career, the payoff for which would be a golden retirement for the former -- this never came because the relationship ended, and the lower earning spouse sought a 50% share of the value of the common project. See par 24 of the QCCA decision. No comment from me on how tenable this theory is -- don't shoot the translator!

 

An interesting nugget is that the first-instance judge (Rigaud J) who found in favour of the appellant was a law professor at the University of Montreal before her appointment to the bench

Attention : courriel externe | external email

Thanks Sam - please forgive my lack of French meaning I cannot read the underlying judgments, but I can't tell from the SCC website summary what is the alleged enrichment in this case and why is it said to be unjust/unjustified?

Dear ODGers,

 

Today, the Supreme Court of Canada granted leave to hear an appeal from a Québec Court of Appeal case, Manon Tanguay v. Kathleen Zicat. The issues are: 

  • Whether existence of community of life agreement between de facto spouses, regardless of its scope and content, constitutes in se bar to action for unjust enrichment 
  • Whether Quebec Court of Appeal erred in laying down principle that de facto spouses who sign community of life agreement must explicitly include therein possibility for them to bring action for unjust enrichment or else they are deemed to have waived this action in advance (establishment of need for inclusion rather than exclusion of right/action) 
  • Whether bringing of action for unjust enrichment can be validly waived contractually and in advance in spousal context; if so, guidelines pursuant to which such waiver may constitute justification for enrichment of one spouse and/or for impoverishment of other spouse  

 

Although it comes from Canada's civil law jurisdiction, it will presumably be an occasion on which the SCC will revisit Moore v Sweet and Kerr v Baranow. One to watch. 

 

Best,

Sam
