PDF Version: What is the Legal Effect of an Unenforceable Agreement in an Unjust Enrichment Claim?
Case commented on: Lemoine v Griffith, 2014 ABCA 46
The recent decision of the Alberta Court of Appeal in Lemoine v Griffith is interesting for what it tells us, in the context of a claim of unjust enrichment, about the legal effects of a prenuptial agreement that was both found and admitted to be unenforceable because of undue influence and a lack of independent legal advice. According to the majority, Justices Ronald Berger and Clifton O’Brien, once the trial judge found the agreement unenforceable for those reasons — and the appellant abandoned his challenge to that finding — the prenuptial agreement was not a factor in either supplying a juristic reason for any enrichment or evidence of the parties’ intentions. However, despite the fact that the unenforceability of the prenuptial agreement was not an issue, in his dissent Justice Frans Slatter would have overturned the finding of undue influence, holding (at para 103) that the “trial judgment cannot stand.” While that is not the only point of disagreement between the majority and the dissent, it is the point that I will focus on in this comment.
