Practice Overview: 

Alun joined Albion Chambers in 2017 after undertaking pupillage and early tenancy in London. He has a broad criminal and regulatory practice, acting for both prosecution and defence.

He came to the Bar following a career as an inspector with the Health & Safety Executive (HSE), where his work ranged from the regional Major Investigation Team, through to the construction and chemical Major Hazard sectors. This provided an expertise not only in a niche area of Regulatory Crime, but also in relation to accidents at work and matters of occupational ill-health such as HAVS, MSD, Asbestos and Legionella. He is also well versed in matters relating to the design function and the Construction (Design and Management) Regulations (CDM).

Alun was an assessment manager for ‘COMAH Top-Tier’ sites (chemical plants with the potential to cause catastrophic major accidents) and conducted fatal accident and major incident investigations together with the police under the ‘Work-related death protocol’.

A common theme in his work for the HSE was the investigation of accidents and incidents and the subsequent conduct prosecutions. This involved consideration of offences at the nexus of gross negligence manslaughter, corporate manslaughter and regulatory matters; an area in which he developed his expertise via an LLM in corporate manslaughter.
