Matthew Simpson

Door Tenant


Matthew practises in criminal law and the complementary areas of financial crime, regulatory proceedings, private prosecutions, licensing and court martial. Since he started practising Matthew has rapidly earned a reputation for building solid client rapport and delivering excellent results.

Matthew successfully completed pupillage at 9BR chambers before becoming a junior tenant. He has since moved back to his family home in the north east where he predominately practises on the North Eastern Circuit, but maintains an interest in work in London and the south east through a door tenancy with 9BR Chambers.


General Crime 

Matthew has a busy defence and prosecution practice in the Crown Court and Magistrates’ Court. He has experience across a range of offences including: fraud, proceeds of crime, firearms, drugs, violence, motoring and sexual offences. Matthew has experience as both prosecution and defence counsel in a variety of single and multi-defendant Crown Court trials.

Matthew has handled demanding cases involving considerations as to dangerousness, fitness to plead and mental health and young and vulnerable witnesses. Matthew has experience in dealing with Criminal Behaviour Orders, Sexual Harm Prevention Orders, and Proceeds of Crime related proceedings and associated orders. As a CPS Grade two prosecutor Matthew frequently advises on issues relating to disclosure.

Financial and White-Collar Crime: Defence

Having previously worked in the front office of a tier-1 US Investment bank, in an FCA registered position, Matthew is positioned well to advance his financial and white-collar criminal practice. He was recently instructed by a band 1 US white-collar law firm on a large scale multi-jurisdictional and multi-enforcement agency internal investigation into allegations of bribery and corruption. Matthew has also been instructed to assist a multi-national law firm defending two company executives accused of fraud, following the insolvency of a multi-billion dollar publicly listed healthcare company.

Financial and White-Collar Crime: Prosecution

Matthew has prosecution experience of financial criminal investigations through previous instructions for the Serious Fraud Office (SFO). Matthew spent over 24 months working for the SFO advising on disclosure, relevance and LPP on a fraud and money laundering case in the energy sector. Matthew gained valuable insights into the development of an SFO case from charge through to trial.

Regulatory & Inquiry Work

As a Nursing & Midwifery Council (NMC) Case Presenter, Matthew has experience of presenting cases relating to interim measures and substantive order reviews.

Matthew has recently received instructions through the Government Legal Department on the Covid-19 public inquiry.

Court Martial

Prior to being called to the Bar, Matthew served as an army infantry officer for over 5 years up to the rank of Captain; leading combat troops on overseas deployments, including multiple active operational tours. Aside from tactical command, he was also involved in overseeing soldiers engaged with internal disciplinary procedures, gaining an early insight into military justice, often attending court martial as an Assisting Officer. Matthew is therefore well placed to both understand military systems and quickly build quality client relationships with servicemen and women.

Firearms & Firearms Licensing

Matthew maintains a keen interest in firearms law, utilising his understanding of firearms from his time in military, as well as a personal interest as a licensed holder. Matthew appreciates that firearms law is often a challenging area of practice and enjoys bringing his knowledge and expertise to bear to deliver solid and well-reasoned advice and advocacy.
