Jonathan’s practice has developed so that he has now been involved in some of the country’s largest and most complex fraud and financial crime cases, including the UK’s largest mortgage fraud .  This is mixed with a civil practice incorporating quasi civil-criminal cases; e.g. POCA civil recovery, cash forfeiture, challenges to Production Orders and Search Warrants. 

Jonathan has been appearing in High Court challenges from an early stage in his criminal practice and has appeared in the Court of Appeal and Supreme Court.  Jonathan acted as junior in the seminal case on PII and disclosure in criminal cases; R v H & C [2003] 1 WLR 3306, Times 24th October 2003..  He was also junior counsel in SOCA v Gales [2011] the very first civil recovery case to reach the Supreme Court, which is further expected to be the first case civil recover case to reach the European Court of Human Rights.  He was counsel for the successful appellant in the leading case on cash forfeiture; Angus v UKBA [2011], High Court.

In R v Rees (2011) - Old Bailey; Jonathan acted as junior for the principal defendant in the Metropolitan police's most notorious un-solved murder case.  After a 5 month abuse of process hearing the Crown offered no evidence in March 2011.   There were around 750,000 pages of material and 5 previous enquiries.   Mr. Justice Maddison, the trial Judge said:

“My firm view is that the legal representatives for all the defendants, faced with a mammoth task, have responded magnificently to it. And the quality of the written and oral submissions that I have received has been of the highest quality. The industry and the tenacity which has been shown by the defence teams is to be commended and the defendants will leave court knowing, if they did not already and I think they must have known before, that they have been very well served”.

The case is said to have involved one of the longest pre-trial legal arguments in the history of English criminal law and has been linked to the ‘phone hacking scandal, has featured on Panorama and been widely reported in all the national newspapers.

In 2017 his client was acquitted of the principal cheat count in a carbon credit fraud case.  The case involved a carbon credit fraud of vast proportions which was linked to HMRC’s Operation Amazon.

In 2018 Jonathan is representing a number of professional clients, including an accountant charged in a conspiracy to cheat the Revenue case (4 month trial at Southwark Crown Court).  He is also instructed in a significant money laundering case at Cardiff Crown Court and is instructed in two applications for Judicial Reviews against the NCA – these are in relation to challenges against search and seizure raids undertaken by the NCA and in respect to a number of Production Orders obtained by the NCA.  Both applications involve the alleged bribing of senior government ministers from Caribbean states.

Jonathan is also instructed in the case of R (Virdee & Ors) v NCA, a Judicial Review which is expected to be the leading case on when law enforcement agencies should apply for search warrants as opposed to using their post arrest powers under PACE.

He is on the CPS Specialist Fraud Panel and the Executive Committee of the Proceeds of Crime Lawyers Association and regularly gives seminars and writes articles on financial crime.   Jonathan is instructed by both solicitors and prosecution agencies and in recent years has been demand with professional clients.
