Florence Iveson’s main practice areas are criminal and public law with a primary interest in extradition. She is described as “an exceptional advocate” in the Legal 500, and is ranked as a Tier 2 leading junior in international crime and extradition. She has received similar plaudits in Chambers and Partners, being described as an “outstanding” junior, “a persuasive advocate in her drafting as well as on her feet” and “always invested in the case and so committed, she goes above and beyond for the client.”
Florence is regularly instructed in complex matters including Part 2 cases, dealing with both technical and human rights issues.
Florence is currently acting for Julian Assange, led by Mark Summers QC and Edward Fitzgerald QC. She is also involved in a number of other part 2 requests at first instance, including representing Jeffrey Lendrum who resists extradition to Brazil for wildlife offences and for the government of the United States in an extradition request relating to large-scale organised crime and money laundering.
Florence often appears before the Divisional Court, in her own right and lead by Queen’s Counsel. Florence has appeared without a leader in the Divisional Court against leading extradition silks, for example in the high profile case of Herba v Italy  EWHC 3211 (Admin) and Mohammed v Portugal EWHC 3237 (Admin).
Florence has acted in many of the leading extradition appeals in recent years, including on fair trial rights in Poland (Lis v Poland  EWHC 674 (Admin)), complex VAT carousel frauds (Malik v Germany  EWHC 3479 (Admin), speciality (Kortas v Poland  EWHC 1356 (Admin)) and section 12A (Puceviciene v Lithuania  EWHC 1862 (Admin)).
Florence has a particular expertise in cases where extradition is resisted on the basis of poor prison conditions and has been junior counsel in many of the lead appeals in this area. Most recently she appeared before 3 judge Divisional Courts in Bartulis v Lithuania  EWHC 3504 (Admin) and Szalai v Hungary  EWHC 934 (Admin) (currently on appeal to the Supreme Court). She has also had a large number of successes both at first instance and on appeal arguing Article 8 family life grounds (for example recently in Demirov v Bulgaria  EWHC 3812 (Admin), DK v Belgium  EWHC 2242 (Admin), Swiercz v Poland  EWHC 1387 (Admin) and BM v Ireland (No. 1)  EWHC 442 (Admin)).
Florence has undertaken a range of criminal work from the Magistrates’ Court to the Crown Court and the Court of Appeal.
Florence’s interest in international crime led to her working on a complex multi–jurisdictional case for the Serious Fraud Office involving possible international corporate corruption. Recently Florence was led by Alison McDonald in the Appeals Chamber of the International Criminal Court, instructed by Lawyers for Justice in Libya and REDRESS, as Amicus Curiae in Saif Al-Islam Gaddafi’s admissibility challenge.
