Appointed to C panel
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.
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.
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.
