(High Court of Australia) Parties to a transaction may choose to enter into it on the basis that certain facts are to be treated as correct as between themselves for the purpose of the transaction, although both know that they are contrary to the true state of affairs, in which case the necessary convention for an estoppel will be established.
Dixon J said: ‘The justice of an estoppel is not established by the fact in itself that a state of affairs has been assumed as the basis of action or inaction and that a departure from the assumption would turn the action or inaction into a detrimental change of position. It depends also on the manner in which the assumption has been occasioned or induced. Before anyone can be estopped, he must have played such a part in the adoption of the assumption that it would be unfair or unjust if he were left free to ignore it. But the law does not leave such a question of fairness or justice at large. It defines with more or less completeness the kinds of participation in the making or acceptance of the assumption that will suffice to preclude the party if the other requirements for an estoppel are satisfied.’
and ‘It is important to notice that belief in the correctness of the facts or state of affairs assumed is not always necessary. Parties may adopt as the conventional basis of a transaction between them an assumption which they know to be contrary to the actual state of affairs. . . Parties to a deed sometimes deliberately set out an hypothetical state of affairs as the basis of their covenance in order to create a mutual estoppel.’
Latham CJ said: ‘The line between estoppel, which precludes a person from proving and relying upon a particular fact, and waiver which involves an abandonment of a right by acting in a manner inconsistent with the continued existence of the right, is not always clearly drawn.’
