“In my opinion these expressions are not all the same, for two reasons. In ordinary speech, an event is something which happens at a particular time, at a particular place, in a particular way. …. A cause is to my mind something altogether less constricted. It can be a continuing state of affairs; it can be the absence of something happening. Equally, the word “originating” was in my view consciously chosen to open up the widest possible search for a unifying factor in the history of the losses which it is sought to aggregate. To my mind the one expression has a much wider connotation than the other.”
