In what circumstances will a judge deny a claim in unjust enrichment?

On the other hand, in Toth v. de Frias (1996), 78 B.C.A.C. 34, Donald J.A. upheld the decision of a trial judge to deny a claim in unjust enrichment. Donald J.A. rejected the appellant’s contention that the trial judge ignored the appellant’s contribution of household services and noted that the trial judge’s decision “rests on the finding that the benefits derived by the plaintiff in the relationship offset her contributions such that in the end no deprivation was established” (para. 22).
