“When interpreting a written contract, the court is concerned to identify the intention of the parties by reference to what a reasonable person having all the background knowledge which would have been available to the parties would have understood them to be using the language in the contract to mean, to quote Lord Hoffmann in Chartbrook Ltd v Persimmon Homes Ltd[2009] AC 1101 , para 14. And it does so by focussing on the meaning of the relevant words, in this case clause 3(2) of each of the 25 leases, in their documentary, factual and commercial context. That meaning has to be assessed in the light of (i) the natural and ordinary meaning of the clause, (ii) any other relevant provisions of the lease, (iii) the overall purpose of the clause and the lease, (iv) the facts and circumstances known or assumed by the parties at the time that the document was executed, and (v) commercial common sense, but (vi) disregarding subjective evidence of any party’s intentions.”
“(2) The notice shall– (a) describe, in general terms, the works proposed to be carried out or specify the place and hours at which a description of the proposed works may be inspected; (b) state the landlord's reasons for considering it necessary to carry out the proposed works; (c) invite the making, in writing, of observations in relation to the proposed works; and (d) specify– (i) the address to which such observations may be sent; (ii) that they must be delivered within the relevant period; and (iii) the date on which the relevant period ends. (3) The notice shall also invite each tenant and the association (if any) to propose, within the relevant period, the name of a person from whom the landlord should try to obtain an estimate for the carrying out of the proposed works.”
“20 (1) Where relevant costs incurred on the carrying out of any qualifying works exceed the limit specified in subsection (3) [now£50 x number of flats], the excess shall not be taken into account in determining the amount of a service charge unless the relevant requirements have been either – (a) complied with, or (b) dispensed with by the court in accordance with subsection (9); and the amount payable shall be limited accordingly. (2) In subsection (1) "qualifying works," in relation to a service charge, means works (whether on a building or on any other premises) to the costs of which the tenant by whom the service charge is payable may be required under the terms of his lease to contribute by the payment of such a charge. (3) The relevant requirements in relation to such of the tenants concerned as are not represented by a recognised tenants' association are - (a) At least two estimates for the works shall be obtained, one of them from a person wholly unconnected with the landlord. (b) A notice accompanied by a copy of the estimates shall be given to each of those tenants… (c) The notice shall describe the works to be earned out and invite observations on them and on the estimates ..... (d) ...... (9) In proceedings relating to a service charge the court may, if satisfied that the landlord acted reasonably, dispense with all or any of the relevant requirements.”
