what is consideration?
magnitude of consideration
The magnitude of the differentiation is irrelevant (Westlake, Thomas)
how many considerations are there in each contract?
Every contract involves 2 reciprocal considerations (one from each party) (all cases)
nominal consideration
Nominal consideration only acts as a formality, causing a gift to be enforceable (Brudner, Benson)
detrimental reliance
Detrimental reliance is irrelevant to contract formation insofar as it involves detriment that is the consequence, not the cause, of the promise (Alleghney College, Dalhousie College).
committing to a pre-existing duty
Committing to a pre-existing duty isn’t valid consideration (Stilk, Hartley dicta, Smith, Raggow dicta, Gilbert Steel, Davidson dicta, Reif dicta)
a promise not to breach one’s legal duty
a promise to do something you have no legal right to do
A promise not to do something you have no legal right to do cannot constitute consideration (White).
a promise not to do something you have the legal right to do
Not doing something you have the legal right to do (forebearance) can constitute valid consideration in certain circumstances (Hamer).
