From: Jason Neyers

Subject: Estoppel by Convention

 

Dear Colleagues:

Those who support the detrimental reliance theory of estoppel, over the promissory or conscience version, will find some useful ammunition in the decision. For example:

¶ 67     The appellants submit that detrimental reliance is a requirement that must be proven in order to find convention estoppel. I agree. The Court of Appeal erred in finding this condition fulfilled by simple proof that a detriment would flow to the party asserting the estoppel if the other party were permitted to resile from the assumed stated facts, without a finding of reliance.

¶ 68     The jurisprudence and academic comments support the requirement of detrimental reliance as lying at the heart of true estoppel ...

¶ 69     Detrimental reliance encompasses two distinct, but interrelated, concepts: reliance and detriment. The former requires a finding that the party seeking to establish the estoppel changed his or her course of conduct by acting or abstaining from acting in reliance upon the assumption, thereby altering his or her legal position. If the first step is met, the second requires a finding that, should the other party be allowed to abandon the assumption , detriment will be suffered by the estoppel raiser because of the change from his or her assumed position (see Wilken, at p. 228; Grundt v. Great Boulder Proprietary Gold Mines Ltd (1937), 59 C.L.R. 641 (Austl. H.C.), at p. 674).

...

¶ 74     This final requirement of estoppel [detriment] has been described as proving that it would be "unjust", "unconscionable" or "unfair" to permit a party to resile from the mutual assumption (see, e.g., Bower, at p. 181; John; The "Indian Grace"; The "Vistafjord"). However, it may be preferable to refrain from using "unconscionable", in order to avoid confusion with this last concept which has developed a special meaning in relation to inequality of bargaining power in the law of contracts (where we speak of unconscionable transactions, for instance) (see Litwin Construction, at p. 468).

 

Cheers,

Colleagues:

Those interested in Estoppel by Convention will be interested in the case of Ryan v. Moore just released by the SCC, which is the first time the SCC has ever dealt with the issue.
