Shearman And Sterling

Mathew is a senior associate in the Litigation practice. His practice focuses on advising individuals and corporate clients on matters connected to business crime, and related compliance and regulatory issues.

Mathew is a U.K.-qualified barrister. A skilled advocate, he has appeared before courts across England and Wales, including the Central Criminal Court, the High Court and the Court of Appeal.

Prior to joining the firm, Mathew worked in the Enforcement and Market Oversight Division of the Financial Conduct Authority for five years where he advised on major criminal investigations and prosecutions undertaken by the organisation. This included cases focusing upon allegations of insider dealing, market manipulation, money laundering, fraud and the carrying on of regulated activities without authorisation. He was also called upon to advise on "dual track" investigations – those that may lead to a criminal and/or regulatory outcome.

In addition, Mathew oversaw all criminal and non-criminal investigations and litigation arising under the Proceeds of Crime Act 2002 and related legislation with a particular focus on asset freezing and forfeiture. Mathew also provided advice generally on AML and financial crime policy. For example, he played a significant role in the enactment and implementation of the Criminal Finance Act 2017 and more recently, advised the FCA and the U.K. Government on potential AML reform.

Prior to the FCA, Mathew spent two years at the Serious Fraud Office where he advised on a range of complex and high-profile cases concerning allegations of fraud, bribery and corruption, including the largest ever bribery and corruption prosecution brought by the SFO at that time and the first investigation arising from the manipulation of LIBOR.

Whilst working at the FCA and the SFO, Mathew regularly liaised with counterparts at other U.K. bodies, such as the National Crime Agency and Her Majesty's Revenue & Customs, as well as overseas prosecutors and regulators at the U.S. Department of Justice, the U.S. Securities and Exchange Commission and alike. He is therefore able to provide a valuable perspective on how criminal investigations and prosecutions in the U.K. interact with other investigations and proceedings both in the UK and abroad.

Prior to joining the SFO, Mathew practised at the Bar for over seven years where he advised and represented individuals and corporate clients, as well as a variety of prosecuting bodies and U.K. Government departments, in relation to a broad range of criminal and quasi-criminal matters with a particular focus on white collar, and serious and organized crime.
