Benjamin is a specialist extradition and public law practitioner.
He has appeared in the Supreme Court, Court of Appeal, High Court, Crown Court, County Court, Magistrates’ Court, the Upper Tribunal and First Tier Tribunal. He has also represented an individual in one of the first UK extradition cases to be determined by the Court of Justice of the European Union. He represents UK and foreign government departments, requesting judicial authorities and individuals. He acts for interested parties at inquests, often concerning deaths in custody, and advises on unlawful detention, prison law and national security.
Benjamin’s extradition practice concerns the full range of challenges to extradition including the validity of European Arrest Warrants, rights to retrial, dual criminality, passage of time, decisions to charge or try and also habeas corpus.
He regularly acts in cases concerning prison conditions and the rights of individuals pursuant to the European Convention on Human Rights (“ECHR”) in Hungary, Poland, Bulgaria and Italy among others. He appeared in the only extradition case to be heard in the Supreme Court in 2018 and returned to the Court in 2021. He has had several successes recently in cases concerning Article 8 of the ECHR representing individuals whose rights to a private and family life outweighed the public interest in extradition.
Benjamin has written articles and given many seminars on extradition law and is a co-author of the latest book on extradition law- A Practical Guide to Extradition Law Post-Brexit.
Since his appointment to the Attorney General’s panel in 2017 Benjamin has regularly appeared in the Upper Tribunal (Immigration and Asylum Chamber) and in the High Court in applications for judicial review. He has also appeared on behalf of the Ministry of Justice at inquests and in the County Court in relation to civil claims made by prisoners.
He is currently instructed as junior counsel for Her Majesty’s Government in the Manchester Arena Inquiry.

Appointed to B panel
On 23 February 2021 the Supreme Court will consider the first ever extradition appeal concerning prison conditions in a requesting state. It will deal with the viability of assurances which purport to guarantee compliance with Article 3 of the European Convention on Human Rights. It concerns the following question of public importance:

Read moreThe two requested persons appealed to the High Court against the decision to order their extradition to Italy. The case concerned the application of section 20 of the Extradition Act 2003 where the requested persons’ conviction in Italy became final following a hearing at the Court of Cassation (the highest court in Italy), at which they were unexpectedly not represented because their Italian lawyers attended a strike.

Read moreThe Supreme Court has given judgment in the case of Konecny v District Court in Brno Venkov, Czech Republic UKSC 2017/0200.
The appeal considered whether or not an individual can properly be described as an accused person when he had been convicted but the conviction is not final because he has an unequivocal right to a retrial.

Appearing as sole counsel against Mark Summers QC, Benjamin acted on behalf of the judicial authority in Hungary, successfully resisting an appeal against the order of extradition of a Hungarian national, Attila Imre.
Read moreLandmark decision on Romanian prison conditions. Benjamin represented the first Appellant, led by Jonathan Hall QC. The Court found that, following the judgment of the Grand Chamber of the European Court of Human Rights in the case of Muršić v Croatia, there is a strong presumption of a violation of Article 3 of the European Convention on Human Rights where the personal space available to a detainee falls below 3m² in multi-occupancy accommodation. Such a presumption can only be rebutted when the reductions in the required minimum personal space are accompanied by various cumulative mitigating factors.
In a technical case with an appeal raised under Section 2 of the Extradition Act, as well as under Article 8, Benjamin successfully acted for a Portuguese national whose extradition was sort for offences concerning an allegation of forging identity documents.
Led by Ben Emmerson QC, Benjamin represented Mr Chihaia. The court considered an acceptance, by the Romanian judicial authorities, that they had not complied with a general assurance issued in February 2015 that there would be a minimum space requirement for prisoners extradited from the UK. The assurance was reaffirmed and therefore was still reliable. Furthermore the court reconsidered Section 20 of the Extradition Act in light of the decision of the Court of Justice of the EU in the case of C-108/16 PPU, Openbaar Ministerie v. Dworzecki.
Led by Edward Fitzgerald QC, Benjamin represented Mr Murphy. The Divisional Court found that no one could be extradited to two Greek prisons (Napflion and Korydallos), unless and until there was evidence of significant improvement due to clear breaches of Article 3 of the European Convention on Human Rights.
Representing the first appellant Benjamin was led by David Perry QC before a Divisional Court including Lord Thomas LCJ. It is the leading case on Section 12A of the Extradition Act 2003. Requesting judicial authorities must have made sufficient progress in a prosecution against an accused individual before that person can be extradited from the UK under a European Arrest Warrant. Decisions to charge and to try must have been made, except where the sole reason for the failure to make those decisions is the absence of the individual from the jurisdiction. The Court also considered mutual legal assistance. If the judicial authority states that it cannot charge or make a decision to try the individual because she is absent from the jurisdiction, then there should be no further questions and the issue of mutual legal assistance is irrelevant to the bar under Section 12A.
A successful appeal against discharge of a European Arrest Warrant issued in order to prosecute a British citizen for conspiracy to transport a large amount of cannabis into Spain in 2007. The Divisional Court found that the judge at first instance erred in finding that extradition would be oppressive. The matter was remitted to Westminster Magistrates’ Court and, after a further appeal, the appellant was extradited to Spain.’
A sentence of 10 years was reduced to one of seven-and-a-half years’ imprisonment in the case of an individual who had pleaded guilty to robbery after taking part in a night-time attack on a homeowner which involved significant violence.
The European Arrest Warrant did not comply with Section 2 of the Extradition Act 2003 and the Court lacked jurisdiction to deal with it. The information in the annex did not form part of the warrant.

On 12 March 2020 Lord Hodge, Lord Sales and Lord Hamblen granted permission to appeal in a case which is the first extradition appeal concerning prison conditions to be heard by the Supreme Court. It will deal with the viability of assurances which purport to guarantee compliance with Article 3 of the European Convention on Human Rights. It concerns the following question of public importance:
“Where a Court is obliged to assess an assurance given to the United Kingdom relevant to extradition, is it is correct that the Court should exercise very considerable caution before admitting evidence which does not relate to an alleged previous breach of an assurance to the United Kingdom, but rather to an alleged breach of assurance to another EU member state? If yes, is it a correct approach that the Court should satisfy itself that such evidence is manifestly credible, directly relevant to the issue to be decided and of real importance for the decision in question?”.
