“There is no dispute that the principles on which a contract ... should be interpreted are those summarised by the House of Lords in Investors Compensation Scheme Ltd v West Bromwich Building Society[1998] 1 WLR 896 . They are well known and need not be repeated. It is agreed that the question is 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. The House emphasised that ‘We do easily accept that people have made linguistic mistakes particularly in formal documents’ … but said that, in some cases, the context and background drove the court to the conclusion that ‘something must have gone wrong with the language’. In such a case, the law did not require a court to attribute to the parties an intention which a reasonable person would not have understood them to have had.”
“In East v Pantiles (Plant Hire) [1981] 263 EG 61, Brightman LJ stated the conditions for what he called ‘correction of mistakes by construction’: ‘Two conditions must be satisfied. First, there must be a clear mistake on the face of the instrument. Secondly, it must be clear what correction ought to be made in order to cure the mistake. If those conditions are satisfied, then the correction is made as a matter of construction’.”
“In my judgment the function of the court in trying to construe the provision of the lease is to ascertain from the terms of the lease as a whole the intentions of the parties evinced by the terms of the lease, regardless of whether or not the parties have used inept words in which to describe their intentions.”
