French v Public Prosecutor of the Central Department of Investigation and Prosecution in Lisbon, Portugal [2013] UKPC 16; [2013] WLR (D) 241
“Although, as a matter of international obligation, a member state (and any European territory for which it was responsible) was required to legislate in such a way as to achieve the aims of Council Framework Decision 2002/584/JHA , including that a formal decision on the execution of an European arrest warrant should be taken within 60 days of the requested person’s arrest, the law derived from the consequential domestic legislation rather than from the Decision, so that where a territory’s legislation provided that the consequence of a failure to meet such deadline was no more than a requirement to notify the issuing judicial authority of the delay and the reasons therefor, the failure did not entitle the arrested person to be released, save where the delay was so excessive that it could no longer be said to be a deprivation of liberty in accordance with a procedure prescribed by law for the lawful detention of a person against whom action was being taken with a view to extradition, within article 5.1(f) of the Convention for the Protection of Human Rights and Fundamental Freedoms.”
