Tom Crowther KC

Year of call: 1993

King's Counsel:

Tom Crowther KC is a senior criminal silk instructed in the most serious and complex
criminal cases. He acts for both the defence and prosecution. His practice encompasses
homicide, large-scale conspiracies, serious sexual offences, fraud and Very High Cost Cases,
often involving vulnerable defendants, expert evidence and substantial evidential complexity.

A former Circuit Judge and Judicial College tutor for long and complex cases and serious
sexual offences, Tom brings significant judicial experience to his advocacy. He is known for
his calm and disciplined approach, forensic handling of expert and technical evidence, and
strategic judgment in cases of exceptional scale and sensitivity.

Tom also has nationally recognised expertise in child sexual exploitation, safeguarding and
institutional failure. He chaired the Independent Inquiry into Telford Child Sexual
Exploitation between 2019 and 2022 and returned as Chair in 2024 to conduct its formal two-
year review of implementation. In 2025 he was asked by the Home Secretary to work with
Government on the development of a model for locally led, victim-centred CSE inquiries and
was subsequently appointed by Oldham Council to chair its proposed independent local
inquiry. He has given oral evidence to the House of Commons Home Affairs Committee on
child sexual exploitation, safeguarding, accountability and the implementation of the
recommendations of IITCSE.

Homicide

Tom Crowther KC is regularly instructed in homicide cases of the utmost seriousness and complexity. He has extensive experience defending allegations of murder and manslaughter involving disputed expert evidence and difficult questions of fitness to plead, causation and culpability.

He has particular expertise in cases engaging mental disorder, exploitation and vulnerability, including modern slavery and diminished responsibility.

Recent homicide work includes:

  • R v Huntley – Defence in a nationally prominent murder case arising from the fatal shooting of Joanne Penney. The case required detailed forensic analysis of ballistic and firearms evidence and concluded by plea following consideration of expert material.

  • R v Rashid – Defence in a murder prosecution founded on allegations of gang activity and joint enterprise. Tom successfully challenged the admissibility and probative value of drill lyrics, including material naming the defendant, and rebutted the Metropolitan Police’s reliance on a purported “super-recogniser” through facial mapping and expert analysis.
  • R v Galek – Defence in a complex murder trial involving an alternative suspect case and highly prejudicial bad character evidence. Following two jury disagreements, the defendant was ultimately acquitted.
  • R v Liversidge – Defence in a murder case in which modern slavery, exploitation and vulnerability were central to issues of culpability and sentence.
  • R v Hassani – Defence in proceedings arising from the alleged murder of Ibrahim Yassin in Cardiff. Public reporting indicates that the case raises issues of mental disorder and diminished responsibility.


Serious Offences & Private Crime

Tom is regularly instructed in serious sexual offence cases, including rape, historic allegations and cases involving young or vulnerable complainants. His experience in this field includes both practice at the Bar and his former judicial work trying serious sexual offence cases.

As a Circuit Judge he was appointed as a Judicial College tutor in serious sexual offences. His work has given him particular experience of vulnerable witnesses, trauma-informed witness handling and the evidential and forensic difficulties which arise in allegations of sexual offending.

Tom also undertakes privately funded criminal work where allegations carry acute personal, professional or reputational consequences. Recent work has included:
  • a half-time acquittal in 2026 for a serving member of An Garda Síochána charged with sexual assault;
  • jury acquittal in a rape allegation involving young people in which the prosecution relied upon alleged confessional Snapchat messages;
  • jury acquittal in proceedings concerning allegations of historic child sexual abuse notwithstanding evidence of contemporaneous complaints;
  • acquittal on appeal in proceedings alleging serious familial violence where conviction would have had substantial personal and commercial consequences; and
  • acquittal in proceedings alleging conspiracy to pervert the course of justice arising from a linked sexual offence prosecution and involving contested digital evidence.

Tom accepts privately funded and Direct Access instructions where appropriate.


Very High Cost Cases (VHCC)

Tom Crowther KC has extensive experience acting in Very High Cost Cases, including some of the largest and most complex criminal prosecutions brought in recent years. He is regularly instructed in multi-defendant conspiracies and large-scale frauds involving prolonged investigations and exceptional volumes of material. He is particularly experienced in managing very large disclosure exercises, including encrypted communications, international evidence and financial records running into hundreds of thousands of pages or many gigabytes, and in maintaining strategic focus in cases of exceptional scale.

His VHCC experience includes:
  • Operation Venetic / Operation Green – Defence in a Very High Cost drugs conspiracy described at the time of conviction as the largest of its kind in the UK, involving sophisticated international offending and extensive encrypted communications across multiple jurisdictions.
  • R v G – Defence in a large-scale, document-heavy fraud prosecution arising from long-term dishonesty within a solicitors’ practice, involving historic accounting records and disclosure running to hundreds of thousands of pages.
  • Operation Vermont– Defence in a substantial and complex prosecution involving extensive documentary, financial and digital evidence and a prolonged investigation.

REGULATORY CRIME


Tom has a substantial regulatory and corporate crime practice, acting for both prosecuting authorities and defendants in complex proceedings involving regulatory breach, financial investigation and public law challenge.

He has particular experience of cash seizure and forfeiture, including cases involving hawala and other informal value-transfer systems, and has advised in relation to multi-million-pound cash seizures, freezing orders and associated investigations.

His work has included drafting guidance for the National Trading Standards Estate and
Letting Agency Team, acting in Directors’ Disqualification proceedings, advising upon
judicial review in relation to CPS investigations and planning matters, and successfully
resisting Environment Act stop notices affecting major developments.

Tom has acted as prosecuting counsel for the Environment Agency, including in R v St Regis
Paper Company Ltd, an appeal concerning the attribution of criminal liability under the
Pollution Prevention and Control (England and Wales) Regulations 2000.

He has also acted for South Wales Fire & Rescue Authority in the prosecution of Cardiff and
Vale University Health Board and prosecutes on behalf of local authorities, including in
substantial fraud cases involving complex commercial and financial evidence.

INQUESTS & PUBLIC INQUIRIES


Tom has extensive experience leading and directing major independent inquiries, particularly in the fields of child sexual exploitation, safeguarding and serious institutional failure.

He chaired the Independent Inquiry into Telford Child Sexual Exploitation between 2019 and 2022. The Inquiry examined decades of abuse and the response of the police, local government, health bodies, education, safeguarding agencies and prosecutors. It involved extensive multi-agency disclosure, substantial survivor engagement and detailed scrutiny of institutional decision-making, culminating in a four-volume report containing findings and recommendations of national significance.

In 2024 Tom returned as Chair to conduct the Inquiry's formal two-year review of implementation, requiring participating organisations to account publicly for progress against its recommendations and examining the arrangements put in place for longer-term accountability.

In January 2025 the Home Secretary asked Tom to work with Government on the development of a model for locally led, victim-centred inquiries into child sexual exploitation, drawing upon the experience of the Telford Inquiry.

In March 2025 he was appointed by Oldham Council to chair its proposed independent local inquiry into child sexual exploitation. Following the Casey audit and the subsequent Government decision to establish a national statutory inquiry incorporating targeted local investigations, the proposed Oldham inquiry did not proceed on its original footing.

In April 2025 Tom gave oral evidence to the House of Commons Home Affairs Committee on the Telford model, survivor participation, institutional accountability, locally led CSE inquiries and the implementation of the recommendations of the Independent Inquiry into Child Sexual Abuse.

His inquiry work involves the direction of complex investigations, management of substantial disclosure, leadership of multidisciplinary legal and investigative teams, engagement with victims and survivors, and the examination of public bodies and institutional decision-making under sustained public, political and media scrutiny.

Tom Crowther KC was called to the Bar in 1993 and took silk in 2013. Shortly thereafter he was appointed as a Circuit Judge, sitting on the Wales Circuit and trying serious criminal cases including sexual offences and complex fraud. During his time on the bench he was appointed as a Judicial College tutor for long and complex cases and for serious sexual offences.

He returned to full-time practice at the Bar in 2018. He has also sat as a Recorder, served as an Associate Judge in the Sovereign Base Areas of Cyprus and acted as a fee-paid Immigration Judge.

Tom plays an active role in professional regulation and governance. He is currently a member of the Bar Council’s Ethics Committee. He was from 2020-2026 a Chairman of the Disciplinary and Inns'; Conduct Committees and has twice served terms as an elected member of the Bar Council.

He is a member of the Criminal Bar Association. His international experience includes advisory and speaking work for CIVIPOL and the United Nations Office on Drugs and Crime (UNODC) on matters including money laundering, trafficking and disclosure.
