Robert Robert

Rob’s busy practice is centered around defending clinical negligence claims and he has worked as a practitioner in this field for over 15 years. 

Initially best known for claimant work, having followed the well-worn “poacher turned gamekeeper” path, Rob now acts principally for doctors, health boards and hospital trusts, no longer accepting instructions to act on behalf of claimants.

He has a reputation for success in unusually difficult cases and is well regarded for being strongly client-focused, ‘down to earth’ and skilled in dealing with experts.  He is consistently recommended by the leading legal directories and is recognised for his ability to approach cases forensically but with an eye on the ‘bigger picture’.

Rob sits locally as an Assistant Coroner and as result of this, along with regularly being instructed to provide representation, he has acquired extensive experience of large and high-profile inquests.

Clinical Negligence

Rob works across the full spectrum of clinical negligence work.  Most of his cases arise from a serious untoward outcome, and many involve allegations of surgical negligence.

Rob often deals with claims of unusual factual or medical complexity.  In terms of financial value; the majority fall within the £50,000 to £1m range.

He regularly provides advice and representation in cases involving allegations of:

  • Surgical negligence
  • Failings in the provision of primary and/or emergency care
  • Failure to diagnose cancer
  • Negligence in the provision of psychiatric care
  • "Secondary victim" psychiatric claims


Rob sits part-time as an Assistant Coroner in Avon and has extensive experience of large and high-profile inquest work as an advocate.

  •  Re Carl Smith (2015) - Mr Smith died of methadone toxicity while on remand in Exeter Prison. He was on a methadone stabilisation programme but had obtained illicit methadone in addition to his prescribed dose. The jury returned a conclusion of ‘drug-related death’; adding a narrative which indicated that both the welfare checks performed by the prison’s healthcare provider, and the overnight observations carried out by the prison staff, were insufficient for a prisoner in Mr Smith’s vulnerable position.
  • Re Shaun Beasley (2012) - Acted for Mr Beasley's family in the inquest following his suicide in a privately run prison. Mr Beasley had killed himself while purportedly under a scheme of increased observation in the prison's healthcare unit. Both the prison and the unit were run by different companies: there was a double finding of neglect by the jury (
