Municipal Mutual Insurance Limited v Sea Insurance Company Limited and Others: CA 26 Mar 1998

The unifying event in an aggregation clause in an insurance policy was expressed in very general terms: ‘all occurrences of a series consequent on or attributable to one source or original cause.’
Held: As long as one could find any act, event or state of affairs which could properly be described as a cause of more than one loss, they formed part of a series for the purposes of the aggregation clause. A series of losses caused by theft and vandalism from the Port of Sunderland over a period of time were attributable to one original cause, namely the inadequacy of the port’s system for protecting the goods of which it was bailee.
Hobhouse LJ said: ‘The judge came to the surprising conclusion that each reinsurance contract covered liability in respect of physical loss or damage whether or not it occurred during the period covered by the reinsurance contract and he went on expressly to contemplate that the same liability for the same physical loss or damage might be covered under a number of separate contracts of reinsurance covering different periods. This is a startling result and I am aware of no justification for it. When the relevant cover is placed on a time basis, the stated period of time is fundamental and must be given effect to. It is for that period of risk that the premium payable is assessed. This is so whether the cover is defined as in the present case by reference to when the physical loss or damage occurred, or by reference to when a liability was incurred or a claim made. Contracts of insurance (including reinsurance) are or can be sophisticated instruments containing a wide variety of provisions, but the definition of the period of cover is basic and clear’.
