As the contract was expressed its evident intention was that the purchaser should be accepted as a tenant and take over the business on or before the date of completion and thereupon the balance of purchase money remaining after payment of the deposit should be paid and the transaction so completed. But the subsequent deviation from this course in which the parties concurred, slight as it may have appeared to them at the time, has now assumed an importance. For by agreeing that only another £800 should be paid down and the remaining £2,300 should remain outstanding, and that the business should be taken over at once notwithstanding that the purchase money had not been paid, the parties brought about a very different position. No doubt it was the obligation of the vendor, the plaintiff, to obtain the acceptance of the defendant as a tenant, although an implied obligation lay on the purchaser, the defendant, to do on his part whatever might reasonably be required of him to enable the vendor to obtain the landlords' consent. But it became no longer necessary to procure the landlords' consent before completion by putting the purchaser, the defendant, in possession of the business and in occupation of the premises. The actual landlords are executors and trustees administering an estate but Currie seems to have been treated by the parties as speaking for them. In fact there is no evidence of his authority; no objection on that score however was taken. The issue whether the landlords accepted the defendant as a tenant, be it an acceptance by the landlords personally or on their behalf by Currie, certainly remained an issue upon which the burden of proof lay upon the plaintiff. That burden was not discharged by making it to appear that the landlords would accept the defendant as a tenant conditionally on payment of £100. The result of s. 133B (1) (a) of the Conveyancing Act upon the operation of the lease is probably that the attachment of such a condition to a consent to assignment could be ignored and the consent treated as unreasonably withheld: an assignment thus being open without consent: cf. Halsbury's Laws of England, 3rd ed. vol. 23, par. 1338. But the contract between the parties studiously avoids stipulating for an assignment of the lease and substitutes the acceptance by the landlords of the defendant as a tenant, and, even if the purpose of doing so is to secure the vendor, the plaintiff, from being held liable to tax upon a premium, yet the purchaser is entitled to have the contract performed in the manner expressed in the bargain. If the plaintiff had paid the amount of £100 demanded by or on behalf of the landlords and the acceptance had been thus obtained, it would have been enough. But that was not done and there was no acceptance of the defendant in fact. There was therefore no performance of cl. 9 by the date of the commencement of the suit. But the defendant had been in occupation of the shop since 24th March 1958 and was in control of the business and he had not been disturbed by the landlords. He had given no notice fixing a definitive time by which the landlords' acceptance of him as a tenant must be obtained and on the contrary, on 30th April he had purported to rescind the contract for fraud, a ground held on the facts to be untenable. It seems clear enough that unless the period between 24th March and 30th April 1958 in which an unconditional acceptance of the landlords had not been obtained be held so unreasonable in its length as to involve a complete failure of performance in an essential provision of the contract, it could not provide an alternative justification for the renunciation or purported rescission of the contract by the defendant. In the circumstances it is clear that the delay in obtaining unconditional acceptance by the landlords of the defendant could not have such an effect. It follows that had the vendor, the plaintiff, accepted the renunciation and sued at law for damages, he would have succeeded. But he did not do so; on the contrary he chose to sue in equity for specific performance and thereby kept the contract open for fulfilment, including cl. 9. While the defendant insisted that the contract was at an end and that he would not perform it, as he did right up to the hearing and of course afterwards, the plaintiff could not reasonably be expected to proceed in obtaining the acceptance of the defendant as a tenant. If cl. 9 began as a preliminary condition it had ceased to be so when the parties proceeded to put the defendant in possession of the business and in occupation of the shop before completion of the contract. In the circumstances that have been narrated it became simply one of the clauses to be put in execution by a decree of specific performance, if such a decree be made.
