‘34. … Insurance policies are, as the judge said at [31], often somewhat repetitive. They are also sometimes clumsily drafted. Without giving evidence, I think it is fair to say that this can arise, even if it did not in this case, from the “pick and mix” approach to the insertion of various possible clauses that insurers sometimes adopt.’
‘In ordinary speech, an event is something which happens at a particular time, at a particular place, in a particular way.’
‘104. As in other policy wordings, we consider that the word “occurrence” should be given its ordinary meaning of something which happens at a particular time, at a particular place and in a particular way. As discussed, each individual case of disease is in our view properly regarded as an occurrence. Accordingly, where there are multiple cases of disease, each is an “occurrence” within the meaning of the clause.’
‘18. In Chartbrook Limited v. Persimmon Homes Limited[2009] 1 AC 1101 (Chartbrook), Lord Hoffmann explained and applied the East v. Pantiles principle as follows at [22]- [25]: “22.

The first qualification is that ‘correction of mistakes by construction’ is not a separate branch of the law, a summary version of an action for rectification. As Carnwath LJ said (at p. 1351, para 50): ‘Both in the judgment, and in the arguments before us, there was a tendency to deal separately with correction of mistakes and construing the paragraph “as it stands”, as though they were distinct exercises. In my view, they are simply aspects of the single task of interpreting the agreement in its context, in order to get as close as possible to the meaning which the parties intended.’ 24. The second qualification concerns the words ‘on the face of the instrument’
