“The Lessee shall pay for such residue”
“Finally, I am encouraged to find that the view that I have formed as to the way in which this type of problem should be approached coincides (save in the one respect of the possibility of abandonment as a separate legal concept) with the views expressed by Slade L.J. in the recent decision of the court in London & Manchester Assurance Co. Ltd. v. G. A. Dunn & Co. (1982) 265 E.G. 39, 135: ‘In the absence of binding authority compelling a different conclusion, I am satisfied that delay on its own, even if unreasonable, will not in general disentitle a landlord from invoking a rent review clause in a case where time has not been made of the essence of the contract. There is, I think, no general principle of the law of contract that mere delay in the enforcement of a contractual right, or in the performance of a contractual duty, by one party to a contract ('A') will entitle the other party ('B') to regard himself as discharged from the obligation to recognise such right or from the contract as a whole (as the case may be). If in such circumstances A has been guilty of unreasonable delay, then, ordinarily, the prudent and proper course for B to adopt, if he wishes to bring matters to a head, will be to serve a notice on A fixing a reasonable period within which A must exercise his right (if at all) or must perform his part of the contract (as the case may be). In some circumstances, of course, the delay on the part of A may be so gross and inexplicable as to make it so clear that he does not intend to exercise his right or to perform his part of the contract that any such notice is unnecessary. But, ordinarily, it will be necessary for B to serve a notice on A or at least to have some communication with him before he can properly and safely regard himself as being absolved.’ It is true that in the circumstances of that case what Slade L.J. said was obiter, but it forms part of a carefully reasoned analysis which I gratefully adopt.”
“In my judgment there is no justification for reading into the lease an implied term that if the landlord did not serve a rent assessment notice on or before December 25, 1974, he had to do so within a reasonable time thereafter. Such an implied term would not have been necessary to give business efficacy to the lease. The landlord would not have wanted it and the tenants benefited by not having it. Any delay on the landlord's part would mean that the tenants went on paying the original rent until such time as the landlord did serve a notice. If for any reasons of their own, such as a general fall in rental values, they had wanted the landlord to come to a decision about the service of a rent assessment notice they themselves could have served what has come to be known, inaccurately, as a notice "making time of the essence of the contract": see Stickney v. Keeble [1915] A.C. 386 and United Scientific Holdings Ltd. v. Burnley Borough Council [1978] A.C. 904.”
