Overview of Practice

Mark Bryant-Heron QC is a specialist in crime with an emphasis on corporate fraud and associated regulatory matters. He is instructed in high profile and complex trials. He advises on criminal and quasi-criminal matters, including matters with an international and cross-jurisdictional dimension, international corruption and anti-bribery advice, advice on the conduct of private prosecutions for fraud, both in this jurisdiction and internationally, corporate advice on the conduct of internal investigation in relation to international sanctions offences, and advice on post-conviction confiscation and asset forfeiture.

Practice Areas

Mark accepts instructions for both defence and prosecution. The emphasis is on fraud and business crime (see fraud and financial regulation below). He has recently successfully defended the CEO of a company charged by the Serious Fraud Office with a £164 million fraud on a bank. (R v. Dartnell and others, Southwark Crown Court 2016 – 2017) He was instructed to prosecute the phone hacking case in 2014 (R v. Rebekah Brooks, Andrew Coulson and others). More recent prosecution work includes the first successful prosecution by the Serious Fraud Office of a corporate for corruption of foreign public officials. (R v. Smith & Ouzman and others, 2014-2015)

Mark’s court based criminal fraud work is complemented by an advisory practice in fraud and related areas. He has been instructed in private prosecutions both in this jurisdiction on behalf of a corporate entity and advising in relation to a fraud based prosecution in Cyprus. He has further advised in relation to international corruption and bribery matters and has advised extensively in relation to revenue fraud and alleged tax evasion schemes operating both in this jurisdiction and abroad.

Mark regularly advises and conducts hearings in relation to post conviction confiscation and asset recovery, most recently in relation to international corruption/bribery allegations.

Mark has advised in relation to extradition proceedings from the UAE for fraud related offences.

Mark advises on judicial review matters arising from criminal litigation, most recently, on a judicial review challenge to investigating agency’s procedure for identifying legal professional privilege material.

Mark has acted in the tax tribunal in revenue fraud related cases, most recently on behalf of the respondent in Electrical Environmental Services v. HMRC [2013] an appeal against a refusal of a £12 million input tax claim on the basis that it was connected with fraud.
