“(1) Where the landlord opposes an application under section 24(1) of this Act on the ground specified in paragraph (f) of section 30(1) of this Act … the court shall not hold that the landlord could not reasonably carry out the demolition, reconstruction or work of construction intended without obtaining possession of the holding if - (a) the tenant agrees to the inclusion in the terms of the new tenancy of terms giving the landlord access and other facilities for carrying out the work intended and, given that access and those facilities, the landlord could reasonably carry out the work without obtaining possession of the holding and without interfering to a substantial extent or for a substantial time with the use of the holding for the purposes of the business carried on by the tenant; or (b) the tenant is willing to accept a tenancy of an economically separable part of the holding and either paragraph (a) of this section is satisfied with respect to that part or possession of the remainder of the holding would be reasonably sufficient to enable the landlord to carry out the intended work.”
“For this purpose the court must be satisfied that the intention to reconstruct is genuine and not colourable; that it is a firm and settled intention, not likely to be changed; that the reconstruction is of a substantial part of the premises, indeed so substantial that it cannot be thought to be a device to get possession; that the work is so extensive that it is necessary to get possession of the holding in order to do it; and that it is intended to do the work at once and not after a time. Unless the court were to insist strictly on these requirements, tenants might be deprived of the protection which Parliament intended them to have. It must be remembered that if the landlord, having got possession, honestly changes his mind and does not do any work of reconstruction, the tenant has no remedy. Hence the necessity for a firm and settled intention.”
“Where, as in section 30(1)(f), proof of an intention is to be supplied, and of an intention related to a particular time, then the genuineness of a declared intention may have to be decided. Considerations as to what may be a landlord’s ‘primary purpose’, or his ‘real intention’, or his ‘main purpose’, or his ‘secondary purpose’, or his ‘real reason’ (to quote phrases which have been used), are only of relevance and assistance in the course of deciding whether the landlord has proved that he genuinely has an intention of doing one of the things specified in section 30(1)(f), and of doing it on the termination of the current tenancy.”
