XL Insurance has defeated a claim against its policyholder Johnston Precast Ltd by proving that it was not responsible for a burst water main in Holland Park in 2004 (J Murphy & Sons Limited v Johnston Precast Limited http://www.bailii.org/ew/cases/EWHC/TCC/2008/3104.html). The installer of the water main, J Murphy & Sons Limited, had to pay £4m to Thames Water for the damage caused by the leakage. Murphy sought to recover the money from the pipe manufacturer Johnston, insured for product liability by XL Insurance. Coulson J held that the cause of the main burst was alkaline attack and a void in the foam concrete backfill, neither of which were the responsibility of Johnston. Mills & Reeve acted for the successful defendant – for further details see the briefing on our website at http://www.mills-reeve.com/dispimg.asp?id=2436.
