PI & Clinical Negligence analysis: The Court of Appeal considered an appeal by the Ministry of Defence (MoD), against a first instance decision holding it liable, at common law and under the Occupiers’ Liability Act 1957 (OLA 1957), for serious injuries sustained by the claimant, a rifleman, as a result of a fall which occurred on MoD premises. The judge at first instance refused to uphold the defence of ex turpi causa advanced by the MoD and made no reduction for contributory negligence. The MoD’s appeal, which was advanced on six grounds, was dismissed in full. Produced in partnership with Emily Lodge, Senior Associate at Quinn Emanuel Urquhart & Sullivan UK LLP.
