65 In our view, the steps taken by Dr Roberman to fulfil an acknowledged need, namely the need for immediate medical assessment at 4.35 pm, were inadequate. There was a substantial risk at 4.35 pm, given the state of the labour, that the patient's membranes might rupture at any time. If the fetus was in a transverse lie, or an oblique lie which did not correct itself, there was a serious risk of cord prolapse or abnormal presentation calling for an urgent caesarean section to be performed, as Professor Ellwood put it, within minutes. The lie of the baby, which at 4.35 pm, was at best uncertain, could have been ascertained by medical assessment. In our view, to rely upon an assumption that, on being notified of the midwife's findings, a registrar would, assuming she was not otherwise committed somewhere in the labour ward, undertake an assessment and take appropriate steps in the light of that assessment left too much to chance. It would have been simple for Dr Roberman to stipulate that he wanted an examination performed, and to ask that he be contacted on his mobile phone with the results on that examination so that he could, if necessary, give further directions to the registrar as to how to proceed. Those instructions were not given, and instead Dr Roberman made a decision to come to the hospital himself, knowing that would take over an hour.
