Jonathan Ashley-Norman KC is a specialist in law enforcement in a corporate setting.

He defends, prosecutes and advises individuals and corporates caught up in regulatory and criminal investigations.

He has advised and defended people from all walks of corporate life and all manner of businesses. His business regulatory and crime work often requires him to master other legal disciplines including sanctions, employment, insolvency, competition, pensions and many other areas.

His experience as both a prosecutor and as defence counsel makes him a popular choice for private prosecutions.

Before taking silk, he was Standing Counsel to the Department for Business Energy and Industrial Strategy and a member of the Attorney General’s A List of Prosecutors, and consequently instructed to prosecute in the most serious of cases. He retains prosecution instructions at the highest level.

He has a substantial health and safety practice, prosecuting and defending in cases brought by the Health and Safety Executive and the Office of Rail and Road.

He has advised people and corporates under investigation and prosecution by the Competition and Markets Authority, the Environment Agency, the Financial Conduct Authority, Her Majesty’s Revenue and Customs, the Insolvency Service, local authorities, the Medicines and Healthcare products Regulatory Agency, the National Crime Agency, Ofcom, the Serious Fraud Office, Trading Standards and many other agencies. He has been instructed by many of those agencies too.

Most of Jonathan’s business crime work necessarily involves suspected money laundering and he frequently helps with the strategic decisions around Suspect Activity Reports.

His offshore practice, especially on the Isle of Man and Gibraltar, has left him familiar with labyrinthine offshore structures, and securing or tearing aside the corporate veil.

He has extensive experience of confiscation work, both defending and prosecuting, including successfully resisting the repatriation of offshore funds, the protection of the interests of third parties and litigating civil recovery orders.
