Mark has extensive experience of representing the deceased’s family, interested parties, employers and highway authorities at Inquests.


Mark has extensive experience of representing bereaved families, employers, highway authorities and other interested parties at Pre-Inquest Hearings and Inquests, including Article 2 Inquests.

Current and recent instructions include:

  • Representing the parents of Arietta-Grace Barnett (d.o.b. 6th June 2017) at the Inquest into her death on 9th July 2019. In the course of the 2 day hearing in Winchester Coroner’s Court on 4/5th November 2020, the Coroner, Rosamund Rhodes-Kemp, heard evidence into the tragic circumstances of Arietta’s death. She had been taken to hospital on 28th June 2019 following the suspected accidental ingestion of a toilet cleaning product. She was detained in hospital until 2nd July 2019 and then discharged, apparently well. On 9th July 2019 she suffered a fatal haemorrhage from an aorto-oesophageal fistula. The evidence at the Inquest was unclear on the precise cause of the fistula although it was postulated that it may have been as a result of the cleaning product, which was a viscous gel-like substance designed to stick to wet surfaces, adhering to Arietta’s oesophagus.
    The Coroner recorded a conclusion of accidental death. Although declining at this time to make a report to prevent future deaths under Coroners & Justice Act 2009, s.7, she has requested further investigations into the composition of the cleaning product in order to establish if it was a possible cause of the fistula.
    Mark acted for the bereaved parents via the Direct Access scheme.
  • Representing family of bereaved at Pre-Inquest Hearings in relation to Inquest into death of elderly man following a cycling accident and subsequent hospitalisation. Cause of death was controversial and Mark was instructed to represent the deceased’s family, making representations as to the scope of the Inquest and the evidence to be adduced.
  • Advising bereaved family, under direct access arrangement, following death of a woman while undergoing medical treatment. Advice covered scope and procedure of an Article 2 Inquest, witness requirements and possible sources of funding.
  • Representing seriously injured interested party at Inquest involving a fatal road traffic accident, including examination of several expert witnesses and making submissions as to the available verdicts.
  • Several cases representing Highway Authorities in connection with fatal road traffic accidents.
  • Representing employer at jury Inquest involving death of employee while operating a ride-on mower.

Mark Sullivan is registered for Direct Access. He has also specialises in Fatal Accident Claims (see Personal Injury entry) and has provided representation at Inquests under Conditional Fee Agreements covering a related civil claim.
