Recent cases:

R v K:

In 2019 Jason Sugarman QC represented a client charged with tax evasion utilising an offshore account in Cyprus. The funds in the account were not declared to HMRC. The client had been acquitted in a tax scheme case concerning selling and marketing environmental and HIV research tax schemes that potentially would have cost the revenue over £100 million after a 6 month trial in 2017. The client pleaded guilty at Southwark Crown Court and was sentenced to an exceptional 18 month suspended sentence.  No confiscation or costs orders were to be pursued. The case was prosecuted by Julian Christopher QC and Michael Attenborough for HMRC and the CPS.

Expert witness in international case concerning major multi-national energy company:

In 2019: Jason has acted as a legal expert on UK compliance law and procedures in proceedings concerning corruption and involving a major multi-national energy company and a Sovereign state. The case is on-going and the case is being heard in a European jurisdiction. It is one of the largest corruption cases ever to be tried in Europe.

University disciplinary proceedings:

In 2018 and 2019 Jason has also been instructed by University undergraduates facing disciplinary proceedings. Most recently his cases have involved Durham and Oxford Universities. These cases are very distressing as they can lead to expulsion and the end of a student’s career at a University. This is potentially very damaging to a student’s long-term future. Jason has been able to draw on his experience from complex cases to ensure that there is an urgent strategy and approach that hopefully can prevent a devastating end to a student’s career options.

 Tax scheme case prosecuted by HMRC and Crown Prosecution Service (2016 – 17)

R v AB & Ors (Southwark Crown Court, 2016) Led junior representing the Sales and Marketing Director in a multi-handed tax fraud. The defendant is alleged to have been concerned in promoting fraudulent investment schemes, dishonestly sheltering approximately £175million from tax and accruing millions of pounds of fees. The case concerns the sophisticated and extensive network of international financial and corporate entities to disguise other defendant’s beneficial interests and to give the impression of legitimate loan funding to increase the tax relief apparently applicable to investors. Initial disclosure in the case amounts to over 1 million pages.

Money laundering case defending against SFO prosecution concluded 2016:

Successfully defended Hong Kong businessman James Sutherland, chairman of a large group of fiduciary companies, securing his acquittal as the main defendant in a criminal trial on money laundering charges concerning $120m proceeds of a boiler room fraud (Southwark Crown Court, 2016)

Representing the former CEO of a foreign exchange company, providing pre-charge advice in relation to an ongoing investigation concerning suspected large scale investor fraud.

Corruption case defending against SFO Prosecution concluded June 2014:

Jason Sugarman represented Robert Manning, former senior partner of Fox Hayes LLP, has been acquitted of a major corruption charge arising from the UK’s biggest ever boiler room fraud. Around 1,000 investors were defrauded of £70m. Nine other defendants were convicted of conspiracy to defraud. It was alleged Mr Manning, aged 63 of Leeds, received a bribe of $869,000 for persuading Fox Hayes Solicitors partners to take on high risk work, resulting in the collapse of the firm and the consequent loss of 300 jobs at the firm. The defence team, led by Mark Rainsford QC, consisted of Jason Sugarman, Stephen Fox –senior partner Ralli Solicitors, Manchester, and Lynn Mahon, associate solicitor. During the trial the SFO’s case was comprehensively undermined in a number of respects. The defendant, who did not give evidence, averred that:

  • He did not improperly influence his partners;
  • The prosecution incorrectly alleged he kept payments made to him secret

from his partners;

  • By reason of custom and practice he had implied authority to receive

separate payment for work introduced by him to the firm;

  • Severe criticism levelled at Mr Manning and his partners by the Court of

Appeal was unjustified and unfair and Fox Hayes LLP collapsed because it overreached itself financially prior to the recession and it was nothing to do with Mr Manning’s conduct.

The trial lasted for three – four months. Mr Manning was the only defendant to be acquitted
