He is recommended by Chambers UK and the Legal 500 as a leading silk in health & safety and product liability. He is also recommended by the Legal 500 in environmental law and personal injury claims, and has been listed by Legal Week as one of the top rated members of the bar.

In relation to his health & safety expertise, Oliver has been described in the Legal Directories as being “an incredibly smooth and persuasive advocate”; “really immersed in the area”; “an outstanding performer”; “very good at inspiring confidence in clients”; “has a razor sharp mind”; is “extremely intelligent” and is “someone who handles complex and sensitive cases extremely well”.

In the field of product liability, the Legal 500 and Chambers UK have commented that Oliver “is absolutely tip-top and shows a deft touch in court that is as good as you would see anywhere at the Bar”; and that he “has a commercial approach and ability to find the right solution for the client”.



Health & Safety

Oliver specialises in health and safety prosecutions, and has been involved in many of the highest-profile and most serious health and safety prosecutions over the last 10 years. He is the chair of Henderson Chambers health and safety practice group, and his practice encompasses all aspects of health and safety and regulatory litigation, representing both companies and individuals prosecuted for health and safety offences.
Oliver has been recommended in health & safety for many years by the Legal 500 and Chambers UK, and won the award for Health and Safety Junior of the Year at the Chambers UK Bar Awards in 2012. He is a founder member and on the executive committee of the Health and Safety Lawyers’ Association.

Oliver has particular expertise in manslaughter prosecutions and other health safety prosecutions arising from fatalities. He successfully defended one of the individual defendants in the prosecution resulting from the Hatfield train crash. More recent cases include successfully defending at trial corporate defendants following: a fatal crane accident, a serious accident at Tilbury docks, and an NHS Trust in a prosecution arising out of a fatal accident to one of its employees.

His experience spans many different industries and sectors. These have included prosecutions arising from accidents at construction sites, accidents at sea, in hospitals and care homes, in docks, in nurseries and schools, from electrical and other fires, and from road and railway accidents.

Oliver has appeared in the Court of Appeal on several occasions in health and safety cases. He appeared in R v Sellafield and Network Rail (CA), the leading authority on sentencing of large companies, and Ashtead Plant Hire (CA) in relation to the application of the Electricity at Work Regulations.
