Jason specialises in serious crime, fraud & financial crime, regulatory law and sports law.

He is ranked as a leading King’s Counsel in both Legal 500 and Chambers & Partners in Crime

His practice in serious crime, where he prosecutes and defends, consists of serious organised crime, with an emphasis of complex homicide, serious/organised violence, modern slavery and large-scale drug matters.  He is recognised as an expert in cases involving complex telephone/electronic evidence as well as cases involving complex legal issues of both joint enterprise and bad character.

Jason’s expertise in fraud & financial crime has meant he has dealt with matters including insider trading, bribery, market manipulation, complex money laundering and tax fraud, where he has been instructed by individuals and corporates – representing them at an early stage in investigations against the Serious Fraud Office & Financial Conduct Authority.  This has led him to appear in both the criminal and commercial courts, as well as advising on international matters.

His advisory practice has meant that he has built a specialism in designing, drafting, operating and auditing anti-bribery, anti-money laundering, anti-slavery policies as required under UK and EU law for corporate bodies both in the UK and internationally.

Jason’s regulatory practice encompasses him representing defendants in professions including doctors and dentists, where he deals with disciplinary proceedings.

In sports law he has represented two defendants in the most complex horseracing corruption inquiry ever conducted by the British Horse Authority.  He has also been involved in defending a coach from the British Judo Authority, who was accused of historic sexual offences against students, where after a large investigation the Crown took no further action.
