BRB (Residuary) Ltd v Connex South Eastern Train Co) Ltd - entitlement to indemnity survived mistake, due to Civil Liability (Contribution) Act 1978 - 23.5.08
BRB is the residuary body which took on liabilities on privatisation of British Rail. It accepted liability to the estate of a railway worker, Malcolm Dines, who had died from mesolthelioma resulting to exposure to asbestos some 50 or 60 years ago. It paid £40K as an interim settlement and expected to pay around another £60K.
At that stage BRB discovered it had made a mistake. It found that it was entitled to a full indemnity from Connex, the successor of the original employer. It sued Connex (insured through Aon Claims Management).
