Gareth is described in the Legal 500 as “an amazingly astute fraud lawyer.” He has been instructed both for the Prosecution (including the SFO) and Defence in many cases of fraud. The LIBOR-rigging trial in which he defended, concluded following acquittals in 2016. In R v Nadir he spent nearly one and a half years preparing the case, followed by a trial lasting some seven months and subsequent compensation proceedings. He appeared in the prosecution of a defendant charged with a multi-million pound film industry fraud; after a three-month trial she was convicted at Bristol Crown Court. In R v Ozakpinar and Others, Gareth was instructed in an allegation of corruption arising out of the employment of consultants by a public body. In R v Alexander and Others he appeared in a lengthy fraud involving the assignment of falsely inflated contracts and conspiracy to bribe.

Gareth led for the Defence in a case against a British diplomat charged with misconduct in a public office arising out of the dishonest grant of visas in the Philippines. He also has experience of appeals in relation to complicated Missing Trader Intra-Community (MTIC) frauds before the First-Tier Tax Tribunal.

He is recommended in both Legal 500 (Fraud: Crime) and Chambers and Partners (new silks: Financial Crime).

Extradition and Mutual Legal Assistance

Hide Show

Gareth has acted for requesting judicial authorities and governments as well as requested persons. He has appeared in many cases before the Administrative Court, and has a broad knowledge of the appellate process in extradition. Gareth acted for the defendant in relation to a US extradition request which, upon conviction, would result in a sentence of life imprisonment without parole. The Administrative Court expressed misgivings in rejecting the argument on Article 3 of the European Convention on Human Rights, and certified a point of law of general public importance: R (On the Application of Wellington) v Secretary of State for the Home Department [2007] EWHC 1109 (Admin). Gareth appeared in the subsequent appeal to the House of Lords ([2008] UKHL 72) and was instructed on the application to the European Court of Human Rights.
