Matthew Chidley

Call 2008


A hard-working and approachable junior, Matthew enjoys a varied practice in the fields of criminal law (including courts martial), police law, coronial, regulatory and disciplinary proceedings. He has considerable experience in factually complex, multi-handed cases, in particular financial crime. Matthew is able to master large volumes of material, presenting complex issues with clarity.

Matthew has been appointed to the SFO and CPS Specialist Fraud panels, and the List of Specialist Regulatory Advocates in Health and Safety and Environmental Law.

Matt is clerked primarily by Tom O’Connor,  Joe Ralph, Joe Fletcher and Josie Ryan.

Matthew was invited by the United Nations Office on Drugs and Crime (UNODC) to provide specialist criminal justice training to Nigerian prosecutors on the prosecution of terrorist offences.


Matthew was junior prosecution counsel in Operation Stagecoach, a boiler room fraud relating to the sale of rare earth metals. Having taken almost £8 million from their victims in less than a year, the four defendants received a total of 29 years’ imprisonment after trial.

Experience and expertise

Appointed to the SFO Panels for both prosecution and POCA work, and the CPS Specialist Fraud Panel (at Level 3 of 4), Matthew is frequently instructed in substantial matters, ranging from investment, revenue and immigration fraud, to money laundering, bribery and corruption and misconduct in a public office.

Matthew advises police forces in operational matters and has experience of prosecuting police misconduct matters, including fast track hearings. He has represented forces in inquests and in the full range of civil applications, including disclosure applications arising out of care proceedings in the Family courts, closure orders, SHPOs, gang injunctions and appeals against revocation of licences for firearms, shotguns and explosives.

He has appeared in extradition proceedings, both at first instance and on appeal to the High Court, and has a wealth of experience in POCA matters, including contested hearings post-conviction, enforcement hearings and cash forfeiture applications.

Recent instructions include acting for the SFO in the prosecution of Alstom Network UK arising out of allegations of corporate corruption relating to contracts for the Budapest Metro; the prosecution of a large-scale boiler room fraud involving the dishonest selling of rare earth metals to a value of nearly £8m; a complex VAT repayment fraud and the prosecution of a firm of corrupt solicitors involved in the facilitation of sham marriages. He has recently been instructed in a long running immigration and PAYE repayment fraud, arising out of a joint investigation by HMRC and the Home Office, the largest of its kind ever prosecuted.

Matthew is adept in the law and procedure relating to LPP and disclosure. He was instructed by the SFO as independent LPP counsel in Operation Steamroller, a £70m boiler room fraud, and was part of a team of independent LPP counsel instructed as part of the SFO investigation following the collapse of the Icelandic bank, Kaupthing. He was also instructed as disclosure counsel in the SFO prosecution of Asil Nadir.

Every case is a new challenge, whatever the size or subject, and I approach them all with the same level of care and attention. Advocacy in court is only part of the process, the final stage, but a case is shaped long before a jury is sworn or submissions are made. There is no substitute for hard work and preparation, although a sense of humour helps.

The devil is in the detail. Particularly in the larger, document heavy fraud cases in which I have been instructed, I have always enjoyed finding the links that others have overlooked.

“There is no substitute for hard work and preparation, although a sense of humour helps”

In recent years, the types of cases I have been fortunate enough to work on have involved working in teams. The input and experience of those I work with is invaluable, particularly in multi-agency operations, and it is a great feeling when those combined efforts result in successful outcomes.
