Profile

Position
Justin leads the specialist Regulatory and Investigations team, and co-heads the Global Commercial Disputes Practice Group.
A former prosecuting advocate, he guides clients through complex, multi-jurisdictional investigations (both criminal and regulatory) in a practice spanning the financial services, energy, construction, pharmaceuticals, and transport sectors. The breadth of his practice encompasses such diverse regulators and prosecutors as the FCA, PRA, NCA, MHRA, FRC, ICAEW, HMRC, CMA and SFO.
He has advised and represented companies and senior individuals in such cases as market abuse, insider dealing, market announcements, cartel and anti-trust conduct, money laundering, and bribery and corruption, often extending internationally to include investigations by the US, European, Japanese, Dubai and Australian authorities. That work includes leading cross-disciplinary teams in negotiations with regulators and ultimately defending at Court or Tribunal.
He has been involved in some of the most high-profile matters of recent years - and also matters which never receive public attention.
His experience is used to advise organisations on compliance programmes (e.g. regarding the Bribery Act 2010, Modern Slavery Act 2015, Criminal Finances Act 2017, and Economic Crime and Corporate Transparency Act 2023) and in leading and managing significant, sensitive and complex corporate internal investigations, and the handling of self-reporting, where appropriate.
Justin is a member of the City of London Law Society Corporate Crime and Corruption Committee and the Pensions Administration Standards Association (Cybercrime and Fraud Working Group).
Justin was appointed MBE in 1998 for his legal work in the British Army.
