Harry Lambert

Call 2008

"Respected junior who “knows the area inside-out"...Extremely dedicated and hard-working. His astute intellect allows him to handle difficult cases and tricky legal issues with aplomb.”
(Chambers and Partners, 2017)

Clinical Negligence

Harry acts for Claimants, the NHSR and the medical defence organisations. He has a heavyweight clinical negligence practice encompassing claims in, inter alia, the fields of neurosurgery, paediatrics, obstetrics, orthopaedics and cardiology.

He prides himself on a sophisticated understanding of paediatric issues and has done a number of such cases. For example, he was junior counsel in Glassenbury v Short, a highly complex case of perinatal hypoxia materially contributing to postnatal periventricular leucomalacia (led by Robin Oppenheim QC). Similarly K was a multi-million pound cerebral palsy claim involving complex issues over care/accommodation (led by Robin Oppenheim QC).

He is often instructed in high value, complex or silk level clinical negligence litigation such as those listed below:

Selected Cases

  • F: Conducting a 4 day trial in an oncological case against a leading QC. The trial judge remarked that the parties were represented by “one silk, and one potential silk”.
  • J: Harry acts as sole counsel against a QC in this case involving an alleged failure to diagnose a stroke.
  • R: Harry acts as sole counsel against a QC in this quantum-only matter pleaded at around £4M.
  • L: This case concerns the failure of a state-of-the-art “custom” knee replacement. Harry acted for one of the foremost knee surgeons in custom knee implants in the country. It is a good example of the interaction between his product liability practice and clinical negligence practice. After drafting a robust and technical 35 page defence, all allegations relating to surgical technique were promptly withdrawn.
  • R: Acting for the NHS without a leader, Harry settled this highly complex paediatric claim with a full pleaded value of circa £5M.
