Year of Call:
James specialises predominantly in Disciplinary & Regulatory and Health, Safety & Environmental Law. He has a considerable background in complex industrial accident cases, fraud and corruption cases, Financial Services, multi-jurisdictional confiscation proceedings and Public Law.
James’ reputation is for prompt assistance to all professional clients in all disciplines; detailed preparation, calm, reasoned and practical advice for all lay clients as well as robust advocacy, fearless cross examination and sound tactical sense in Court.
In 2014, James was the Chambers and Partners Professional Discipline Junior of the Year, and in 2017 he was the Chambers and Partners Health and Safety Junior of the Year.
James’ Health & Safety and Environmental work leads to appearances in Courts at every level but his caseload is at the higher end of the scale of seriousness.

James’ Health and Safety-related work is extensive and nationwide, recently extending to Australia. He regularly represents corporates and individuals in jury and non-jury inquests particularly when an individual is thought to be at risk of prosecution. In Inquests, robustly managing an individual’s right against self-incrimination in a potentially hostile tribunal is a particular specialty. James has extensive experience in Article 2 Inquest proceedings having appeared in a number of prison death cases and deaths relating to police activity including the Tomlinson G20 Inquest and the suicide of a mental health patient in a south Wales hospital. He has particular experience with health and safety issues arising out of care home facilities, having represented a number of care home owners and service providers arising out of fatal accidents to and/or unexplained deaths of residents.

He regularly appears in the Crown Court and, when necessary, the Court of Appeal Criminal Division, recently for the successful appellant in R (HSE) vs. ATE Ltd (2018). Consideration of relevant regulations and criminal liability (or not) as a result of alleged breaches is a specialty.

His recent homicide experience includes defending for the Princes Sporting Club Ltd when the company was prosecuted for Corporate Manslaughter, defending in R v. John Binning (gross negligence manslaughter arising out of a fall from height in farming/commercial premises) and (in 2016) defending Dr Errol Cornish (charged with gross negligence manslaughter) arising out of a death in hospital alongside an NHS Trust charged with Corporate Manslaughter.
In 2016, James defended in R (MKBC) v. Travis Perkins Trading Company Limited – one of the first fatal accident prosecutions/sentences of a multi-billion pound turnover company under the new Sentencing Council’s Guideline on Health and Safety Offences, Corporate Manslaughter and Food Hygiene Offences. He has lectured extensively on the new guideline to the Health and Safety Lawyers Association (in London and Scotland) and to solicitors and corporate clients alike.
In addition to his experience in relation to major industrial accidents for power, utility and COMAH installations for RWE nPower PLC and BOC (UK Ltd), he was instructed by Freshfields Bruckhous Deringer for ConocoPhilips (U.K.) Ltd in relation to a prosecution arising out of the LOGGS gas emission in the North Sea – one of the biggest ever of its kind – which went to the Court of Appeal (Criminal Division).
In the autumn of 2016 James was instructed to advise Masuri Group Ltd (manufacturers of cricket helmets) in relation to its appearance before the NSW Coroner (Australia) for an Inquest into the death of cricketer Phillip Hughes.
In 2017, James’s prosecution experience included representing, as first Junior, the BFK JV in a prosecution arising out of a fatality on the Crossrail project and Western Power Distribution (South West) PLC arising out of the fatality of one of its overhead linesmen.
He is currently instructed for the site owners of the Didcot Power Station, which collapsed in February 2016 leading to four fatalities. James has experience of Public Inquiry work and is currently instructed for one of the Core Participants in the Grenfell Tower Public Inquiry.
Although predominantly a defence advocate, James is instructed by the Maritime and Coastguard Agency in relation to prosecutions arising out of fatal accidents at sea and prosecuted R (MCA) v. Bowman-Davies in 2017 for a double fatality which resulted in the longest prison sentence ever handed down in an MCA prosecution for offences pursuant to the Merchant Shipping Act and its regulations.
He also has a well-established practice defending death by dangerous driving cases in the Crown Court and Court of Appeal Criminal Division particularly for commercial drivers.
James manages the UK Health and Safety Lawyers Group on LinkedIn and was awarded the prize of Health and Safety Junior of the Year in the Chambers and Partners UK Bar Awards 2017.
His fraud and financial services experience includes allegations of tax fraud, VAT/MTIC fraud, FCA interventions and investigations, and corruption at the very highest level especially appearing as a Leading Junior. The management of evidence, disclosure, privilege and unused material in vast cases are particular specialties.
His financial services work includes money laundering offences and investigations and complex multi-jurisdictional confiscation proceedings involving Switzerland, the Channel Islands, Spain, Andorra, the Turks and Caicos Islands, Gibraltar and the United States of America.
James has an established practice representing corporate clients, Trusts and fiduciary services companies in relation to financial structures and in particular the impact of proceedings/investigations on property held in off shore structures and/or international jurisdictions.

In 2011 he went on to represent Dr Patel at the G20 Protest Inquest into the death of Ian Tomlinson, one of the most high profile inquests of recent years. As part of his GMC experience, James represented a Shropshire GP charged with deliberately administering a fatal dose of diamorphine to one of his patients in a so called “mercy killing”. The case amounted to an allegation of murder, attracted national publicity but was resolved by the Doctor receiving a formal warning.
In 2014 he conducted FtPP hearings for Consultants and Senior Clinicians in relation to misconduct and performance issues including a consultant Breast Cancer Surgeon in relation to apparent missed cancer diagnoses. He represented a Senior Pathology Consultant at the 2014 Northern Ireland Inquiry into Hyponatraemia Related Deaths.
