Chambers UK 2022, Personal Injury

Accidents at work/deaths at work can result in both criminal proceedings against the employer in question as well as private law claims for damages arising from the accident. Insurers tend to be involved in both proceedings and since commencement of his practice Derek’s practice has always involved representing companies or individuals being prosecuted under the Health and Safety at Work Act/daughter legislation as well then acting for them in any subsequent civil proceedings (or inquests).

Derek frequently receives instructions from the employer’s liability insurers of companies and individuals who are facing health and safety prosecutions in the criminal courts and he is very experienced in relation to trials in the magistrates court (e.g. R v Bestway Coventry Magistrates Court; a case under s. 3 of the Health and Safety at Work which involved a so-called “HTML defence”) and the Crown Court with a jury (e.g R v Thomas and R v County Mall Management Limited).
