View Financial CrimeR v F and Others, 2023
Representing 14 Applicants before the Investigatory Powers Tribunal in a complaint relating to Unlawful interception of Data following a Pan European Operation. The operation led to Worldwide arrests of alleged Master Criminals involved in the most serious criminality. The challenge before the IPT has the potential to lead to the staying of all Criminal Trials relying on evidence obtained from the interception of data and as such is the most high-profile Litigation in the Country.
I am also instructed in the associated Criminal Trials wherein the charges include Conspiracy to Murder, Conspiracy to Possess Automatic and Semi-Automatic Weapons with Intent, and a multitude of Drugs Conspiracies at the very highest end.
Complexities: the interpretation of the Investigatory Powers Act and the concept of ‘Bulk interception’ wrongly being the subject of Targeted Equipment Interference Warrants; lack of candour and its impact on the validity of the Warranty granted by the Commissioner; breaches of ss. 9 and 10 of the IPA and the consequences and potential breach of Article 8 arising from the unlawful interception of Communications.
