Corporate Manslaughter

R v Peter Mawson Ltd and Peter Mawson Preston Crown Court – Mark represented both defendants from the outset of the police investigation into the death of an employee who fell through a sky-light whilst undertaking roof repairs. The director was directly involved in the works and this was a case of no safety measures being in place. Both Defendants were charged with manslaughter. Company pleaded to corporate manslaughter and s.2 HSWA. It was fined £215,000 with significant time to pay. Director pleaded to s.37 HSWA and received a non-custodial penalty. The prosecution unsuccessfully argued profit before safety. The judge rejected evidence from ex-employees as to a callous disregard for safety.

R v Sterecycle Ltd – Mark advised the Company, charged with corporate manslaughter, and its administrators pre-trial. As a result the Company was unrepresented at trial.

At present Mark is assisting four Companies and their directors, under investigation by the police. These include a television film studio, road works contractor, a building contractor and a national retailer.

Recent Notable Cases

R v Bloor Homes Ltd Reading Crown Court – forthcoming trial defending national developer for alleged breach of Consumer Protection from Unfair Trading Regulations 2008.

R v The Home & Motor Club Ltd and David Mellen Cardiff Crown Court – Mark secured the acquittal of both Defendants charged with 28 counts of fraud and breaching the Consumer Protection from Unfair Trading Regulations 2008. HHJ Fitton QC ruled in favour of an application of no case to answer at the close of the prosecution’s case and directed the jury to acquit. Both Defendants had previously pleaded guilty when represented by different counsel and solicitors, such pleas being set aside after the instruction of Mark and on his application. The basis of that application was a failure to follow the procedure for indication of sentence in R v Goodyear [2005] EWCA 888, inappropriate prosecutorial inducement and flawed advice by non-specialist lawyers.

Wolverhampton BC v JHAI Ltd Wolverhampton Crown Court – Successfully defended Building Regulations Approved Inspector and its Managing Director for charges brought under the Consumer Protection from Unfair Trading Regulations 2008. Retained by Company to advise on other trading standards investigations.

R v Dunwoody Building Legislation LLP Leeds Crown Court – representing Building Regulations Approved Inspector at trial in autumn 2019 for breach of the Regulatory Reform (Fire Safety) Order. As with the JHAI case arguments will revolve around a misunderstanding of an A.I.’s power.

Various v TJ Morris Ltd (Home Bargains), Nationwide, forthcoming trial Wolverhampton Crown Court – retained counsel advising and representing to trial company on licensing, criminal investigations and prosecutions.

Various v Sainsbury’s Supermarkets Ltd Nationwide – multiple instructions defending licensing prosecutions.

Financial Crime

Mark has throughout his 20 years of practice specialised in serious crime and continues to be instructed in such cases where a junior is required with experience, an attention to detail and proven ability.

Mark’s first experience of fraud work was as a led junior in the London City Bond frauds of the late 1990s. Ever since he has represented both companies and directors charged with fraud and facing confiscation proceedings, individuals on money laundering allegations and has advised companies with regards to the Bribery Act 2010. Mark attributes his success in the criminal regulatory field to the years of practice he has had in serious crime, in particular financial.
