"Leave to appeal shall be given only if the court is satisfied: (a) that the determination of the question will substantially affect the rights of one or more of the parties; (b) that the question is one which the tribunal was asked to determine; (c) that on the basis of the findings of fact in the award ... (i) the decision of the tribunal on the question is obviously wrong; or (ii) the question is one of general public importance and the decision of the tribunal is at least open to serious doubt; and (d) that despite the agreement of the parties to resolve the matter by arbitration it is just and proper in all the circumstances for the court to determine the question."
"The market rent means the rent at which the demised premises, assuming the same to be a warehouse with all necessary consents for use as a warehouse, might at the commencement of the period in question reasonably be expected to be let in the open market by a willing landlord by a lease for a term equivalent to the then unexpired residue of the term hereby created with vacant possession, and subject to the same incidents as are applicable to this lease and upon the supposition if not a fact that the lessee has complied with the lessee's covenants and obligations hereunder, but without affecting the landlord's remedies in respect of them disregarding, if they apply, the matters set out in paragraphs (a), (b) and (c) ofsection 34(1) of the Landlord and Tenant Act 1954 , but the market rent shall not be less than the rent payable in respect of the immediately preceding period."
"In addition to the initial rent and to the market rent before defined, the lessee shall pay to the lessor a supplementary rent of£11,230 per annum during the first 15 years of the term hereby demised, such supplementary rent not to be subject to the reviews referred to in this clause."
"I agree, however, with Mr Brock that if the premises to be valued do conclude the building, then the provision within the actual lease for the supplemental rent must be included in the hypothetical lease, and I am grateful to Mr Brock for setting out the case law in support of this view. The hypothetical lease must therefore contain provision for the payment of the supplemental rent for the first 15 years of the term."
"29. There is every reason as a matter of construction for the provisions in respect of the supplementary rent to be included in the hypothetical lease. Clause 2(d) provides for the hypothetical letting to be subject to the same incidents as are applicable to this lease. On the principles laid down in Law Land v Consumers Association[1982] EGLR 109 , the hypothetical lease will contain all the provisions of the actual lease other than the parties, the term, the commencing rent and other necessary amendments. If, as appears to be accepted, the principal provisions for rent review in clause 2(a) to (f) will be contained in the hypothetical lease, why should the provision for the payment of supplementary rent in clause 2(g) not also be contained in the hypothetical lease? There is no necessity as there was in Law Land to remove the provision. The hypothetical lease will operate perfectly well with such a provision. It corresponds to the reality of the position at the commencement of the lease. There is no reason as a matters of language for it to be excised. Compare Norwich Union v BT [1995] Estate Gazette Summaries, case 148. 30. The landlord may seek to rely on such decisions as Lister Locks v TEI[1982] 2EGLR 124 where a term was implied to exclude the relevant provision, but in this case the context in which the building was constructed militates strongly against the implication of the term, which as is well known, will be only be implied where it is necessary to give business efficacy to the contract. In this case the tenant builds and partially paid for the building. In addition, the landlord required rental compensation for its contribution to the costs. The supplementary rent will only be payable during the first 15 years, or the hypothetical term, and not be subject to review. The initial rent was no doubt adjusted to reflect payment of the supplementary rent; however the supplementary rent was not payable only for the first five years of the term, but for the first 15 years of the term. Was it seriously intended that payment of the supplementary rent should be ignored for the purposes of the review as at1st January 1978 and1st January 1983 ? That seems extraordinary unlikely. If that is so, then the provision for the supplementary rent would presumably have had to be incorporated into the hypothetical lease for the purposes of those reviews. If so, what justification can there be for excising it during subsequent reviews. I can see a very powerful argument for saying that the existence of a supplementary rent should not be taken into account if the rent on review is to be a ground rent. That would introduce double counting in the tenant's favour. However, if the rent is to be a rack rent reflecting the value of the building, commercial common sense dictates that the construction of the lease should reflect reality as well as the language of the instrument and provide for payment of the supplemental rent for the first 15 years of the term at each review."
