Alex Mullen

Called to the Bar:2021

  • Alex was called to the Bar by Gray’s Inn in March 2021 and joined Chambers as a pupil in September 2021. Following successful completion of his pupillage Alex was invited to join as a full member in February 2023.

    Corporate & Financial Crime

    In 2022 Alex began work as part of the wider defence team for a senior G4S executive accused of defrauding the Ministry of Justice, instructed by Hickman and Rose. All three executives were acquitted in 2023 after the Serious Fraud Office offered no evidence against them.

    In 2023 Alex was seconded to BCL Solicitors LLP, focusing on sanctions and proceeds of crime matters. Working alongside BCL’s world-renowned team, Alex advised individual and corporate Designated Persons on all aspects of sanctions including licencing and challenges to designation. Through this secondment Alex has gained familiarity with complex multi-jurisdictional trust and corporate structures; most notably in the British Virgin Islands, Cyprus, and Russia. Alex co-published an article for BCL’s own Insights blog on the licencing regime and a news analysis piece for Lexis Nexis on the expansion of sanctions to Belarus and beyond.

    Alex accepts instructions in this area in his own right, including advisory and drafting work. Alex has recently been instructed in civil forfeiture cases to which he brings his pragmatic and tenacious approach, often with great effect.

    Alex has supported members of chambers with matters arising from allegations of corporate manslaughter and health and safety.

    Regulatory and Disciplinary 

    Alex came to chambers having worked for the Health and Care Professions Council (HCPC) as both a Case Manager and Presenting Officer. This in-house regulatory experience means that Alex is uniquely placed to offer his frontline experience in acting both for and against regulatory bodies of all types.

    As a result of his work in this field, Alex has a wealth of experience of complex medical evidence.

    Alex has assisted members of chambers in Financial Conduct Authority proceedings, Solicitors Regulation Authority / Bar Standards Board matters and cases before niche regulators including the British Horseracing Authority and the Institute and Faculty of Actuaries. Alex frequently conducts disciplinary hearings on behalf of regulators at every stage in his own right, as well as advising such bodies on cases from complaint to conclusion.

    Alex’s experience of regulatory work extends to acting as a disclosure junior (instructed by Hickman and Rose) in a complex multi-national market manipulation matter brought by the FCA.


    Alex is regularly instructed to prosecute and defend in both the Magistrates’ and Crown Courts. Alex has significant breadth of experience ranging from violent offences and road traffic matters through to sexual offences and drugs cases. Alex has particular familiarity with driving offences and is often instructed to make special reasons and exceptional hardship arguments in both the Magistrates’ Court and the Crown Court on appeal.

    As a pupil, Alex often assisted senior members of chambers in relation to high-profile and politically sensitive criminal cases of the utmost seriousness, as well as cases with particular legal and factual complexity.
