“The insurance may provide that, when considering what may be regarded as one Claim for the purposes of the limits contemplated by clauses 2.1 and 2.3 : (a) all Claims against any one or more Insured arising from: (i) one act or omission; (ii) one series of related acts or omissions; (iii) the same act or omission in a series of related matters or transactions; (iv) similar acts or omissions in a series of related matters or transactions and (b) all Claims against one or more Insured arising from one matter or transaction will be regarded as One Claim.” (iii) the same act or omission in a series of related matters or transactions; (iv) similar acts or omissions in a series of related matters or transactions will be regarded as One Claim.”
“The word “series” does not, I think, normally carry with it the notion of a sequence with some connexion between the items in the sequence. Here whatever connection there is between the occurrences is to be found in what constitutes the further requirement, viz, that they are attributable to one source. The problem is do they form a series ? Prima facie I think not. It is probably true that no two of the relevant occurrences happened at the one time so that it may be taken for granted that they occurred one after another, but I do not regard that as itself sufficient to constitute them occurrences in a series ……..The numbers 1,2 and 3 are a series of numbers because they are in a particular order, but I would not regard the numbers 7,16 and 100 as a series of numbers because they are in no discernible order. It seems to me that order is the characteristic of a series and there is no order in the occurrences here under consideration. The difficulty with the phrase here is to attribute any particular meaning to it, other than the unlikely one, that it merely excludes occurrences happening at the one time. This is because the element of connexion between occurrences which could perhaps constitute them in a series does not depend upon the word “series” itself, that is, that they are attributable to one source. This is dealt with expressly. To reject the construction of the phrase “occurrences in a series” means no more than any number of occurrences not happening at the one time does, it must be conceded, leave the words “in a series” with problematical positive significance. Nevertheless ………I am not satisfied that the occurrences with which we are concerned are occurrences in a series simply because they happened one after the other………”
“When is an occurrence part of a series of occurrences ? To form part of a series there must be some connecting factor which links occurrences which would otherwise be separate. In the Australian case (Distillers Co. Biochemicals (Australia) Pty Ltd v Ajax Insurance Co Ltd[1974] 130 CLR 1 ) the majority considered that the occurrences must be of a sufficiently similar kind to qualify for forming part of a series. In this case the claims might properly be all described as occurrences of misselling of pensions. On the assumed facts the claims are sufficiently related to form part of a series; and that would be so, I think, whether or not they were attributable to one source or original cause. ”
