Accordingly, the crucial question is whether it is now too late to apply to the Minister for his consent. In our opinion it is not too late. Section 272 (2) provides that a transfer shall not be effected, or if effected shall not be valid, unless the Minister's consent thereto has been obtained. If the sub-section simply provided that a transfer should not be effected unless the Minister's consent thereto had been obtained, it would be open to the construction that every memorandum of transfer given without his previous consent should be invalid. But the sub-section also provides that such a transfer shall not be valid unless his consent thereto has been obtained. This provision appears to us to mean that an application may be made for the consent of the Minister not only before but also after the instrument of transfer has been given and that upon obtaining his consent the transfer shall be valid according to its tenour and, in the case of dealings under the Real Property Act, when registered effective to pass the legal estate or interest. In other words the parties may enter into a transfer subject to a condition that it is not to become effective unless the Minister's consent has been obtained. Prima facie this would import an obligation on the part of the person giving the transfer to do all that was reasonable on his part to the end that the Minister's consent might be obtained. Such a condition could be either express or implied. There is in the present case no express condition as in Roach v. Bickle [1] , but we think that such a condition should be implied. It has been held in cases too numerous to mention both before and after the classic statement of Bowen L.J. in the case of The Moorcock [2] that the law raises an implication from the presumed intention of the parties where it is necessary to do so in order to give to the transaction such efficacy as both parties must have intended that it should have. Similar implications were raised under other sections of the Crown Lands Consolidation Act in Duncan v. Mell [3] , and Egan v. Ross [4] . Section 272 does not limit the time within which the application for the Minister's consent must be made and, in the absence of such a limitation, there is no reason why the application should not be made at any time before it is too late for his consent to make the transfer effective. Sub-section (3) of s. 272 provides that a foreclosure or transfer in contravention of the section shall be void and any agreement or contract for the sale of any holding made without the permission of the Minister shall render such holding liable to forfeiture if such agreement or contract be not submitted for the approval of the Minister within three months from the date of execution thereof. These provisions, we think, relate to transfers and agreements and contracts by mortgagees exercising their powers of sale and not to transfers and agreements and contracts of sale generally. Even if they do apply generally, their effect is not to prevent the Minister giving his consent where the approval is not sought within three months but only to make the holding liable to forfeiture. In the present case we agree with his Honour that the application could be made at any time during the term of the lease. If the Minister's consent is obtained the transfer will become capable of valid operation and the plaintiff will be in a position to register the memorandum of lease under the Real Property Act. The question the Minister will have to consider will be whether the plaintiff's holding, when added to the area proposed to be acquired by transfer, would in the opinion of the Minister substantially exceed a home maintenance area. The material date is the date of the proposed transfer, and the same question arises whether the proposal is to transfer the land by way of sale lease or otherwise. There is of course a question whether the sub-section requires a further consent of the Minister to a transfer by way of sale if the option is exercised. We agree with his Honour's view of the meaning of the option of purchase and think that, apart from the failure to obtain the consent of the Minister, it became immediately exercisable upon the death of the lessor and that it continued to be exercisable from that date until the expiry of the period the parties intended to define by the use of the words "within two calendar months from the date of the expiration" of the lease. Literally, these words appear to mean what his Honour held they meant, namely, that the option was exercisable in the lifetime of the lessor during a period of two months commencing upon the expiration of the lease. But this would involve a holding over by the lessee until he exercised the option and it may be that the words are capable of referring to a period of two months before the expiration of the lease. It would be unnecessary to resolve the difficulty if the exercise of the option rested on the notice of 5th April, 1951, which was given at a time which satisfies either construction. And we cannot agree with his Honour that the notice of 5th April, 1951, is necessarily invalid in the sense that it can never fulfil the condition on which the exercise of the option depends because it was given before the Minister's consent had been obtained and the memorandum of lease registered under the Real Property Act. The consent is a condition precedent to the validity of the transfer as a whole, and if it can now be obtained the condition will be satisfied for non-fulfilment of which it lacked validity.
