Suttor v. Gundowda Pty. Ltd. and Gange v. Sullivan are consistent with Aberfoyle Plantations Ltd. v. Cheng, and support the view that where a conditional contract fixes the date by which the condition is to be fulfilled the contract may be terminated if the condition has not been fulfilled when that date arrives, and that it is unnecessary to give any prior notice to the other party. The question is whether a similar conclusion should be reached when no time for fulfilment of the condition is fixed by the contract, and it accordingly must be performed within a reasonable time. There is little authority on the question, and it must be approached from the standpoint of principle. The condition with which we are concerned is not one which it was entirely in the power of the appellants to fulfil. Although they might use their best endeavours to find a buyer and complete a sale, it still remained necessary for them to find someone prepared to buy. Although, in fact, the appellants did not make reasonable efforts to satisfy the condition, it is impossible to say that they must have effected a sale within a reasonable time if they had made all reasonable endeavours to do so. It seems inappropriate that one party to a contract should be able to give a notice requiring the other to complete a sale, when that other party has not promised to do so (his promise only being to do all that was reasonable) and when it is not necessarily within his power to do so. The doctrines of equity enable a party to a contract to obtain specific performance notwithstanding his failure to carry out his obligations within a stipulated time, when that time is not of the essence of the contract. The party not in default has a corresponding power to limit a particular time within which the other contracting party is to perform his obligations. These principles have recently been discussed by this Court in Louinder v. Leis [26] . They apply, in my opinion, only where the party to whom a notice may be given is under a contractual obligation to act. In the present case no doubt the appellants might have been given a notice requiring them to make reasonable efforts to sell, but they could not have been required to make a sale, for that was beyond their power. Moreover, a notice can only be given when the party to whom it is addressed is either in breach of contract, or guilty of unreasonable delay. A purchaser might have made all reasonable efforts but yet have been unable to complete a sale, and in that situation the vendor would not be able to give a notice to complete, and would, if the appellants' argument is correct, be bound indefinitely to a contract that might never result in a sale. For these reasons I consider that when the time has elapsed for performance of a condition which is not a promissory condition, but a condition precedent to the obligation to complete a contract of sale, either party, if not in default, can elect to treat the contract as at an end if the condition has not been fulfilled or waived, and that it is not necessary first to give a notice calling on the party in default to complete the contract or fulfil the condition. What I have said is, of course, subject to any sufficient indication of a contrary intention in the words of the contract itself. The conclusion that I have reached is supported by the judgment of Lord Keith in T. Boland and Co. Ltd. v. Dundas's Trustees [27] , with whose reasoning I respectfully agree. It accords also with the judgment of Cross J. (as he then was) in In re Longlands Farm [28] , a decision whose authority on this point is weakened by the fact that a notice to complete had in fact been given. A contrary view was taken in Hunt v. Wilson [29] by Cooke J., who considered that a notice making time of the essence is necessary. Although in Aberfoyle Plantations Ltd. v. Cheng [30] an erroneous view may have been taken of the nature of the condition there considered, nevertheless, in my respectful opinion, it was correct to hold that the time fixed by the contract for performance of the condition was not to be extended by reference to equitable principles, and the same conclusion should be reached when the condition is to be performed within a reasonable time.
