We examine whether messages from an EncroChat phone can be used in evidence.
A vast number of cases are awaiting a criminal trial that will rely, to a greater or lesser extent, on the admissibility of communications made via the supposedly highly encrypted Encrochat service.
The Court of Appeal has now issued a ruling following preliminary rulings at Liverpool Crown Court. Whilst this ruling does not mean that guilty pleas are inevitable, for some defendants it will nonetheless present a significant hurdle for them to surmount.
The main question was whether the communications were intercepted at the time they were being transmitted or, as the judge found, were recovered (intercepted) from storage. If the judge was right, subject to a number of subsidiary arguments, the evidence would be admissible.
The EncroChat material was obtained by a Joint Investigation Team (JIT) of French and Dutch investigators and prosecutors by interfering in the EncroChat communications system. It was then supplied to the United Kingdom authorities where it was used in a large number of investigations, including the one which led to the present case. The judge was required to hear evidence about how this occurred, and then to make findings of fact. He then had to apply the United Kingdom domestic law governing the admissibility of such material, which is found in the Investigatory Powers Act 2016 (“the 2016 Act”).
The 2016 Act adopted a domestic law framework which is unique in Europe and which resembles previous regimes. Historically, intercept material (classically phone tapping, but not limited to that) could be lawfully obtained by the authorities. Subject to a number of immaterial exceptions, it could not be used in evidence in proceedings but was reserved for intelligence use. The policy justification for that approach has been debated on many occasions and centres around protecting sensitive capabilities and wider operational and practical concerns. All were discussed in Intercept as Evidence, December 2014 Cmnd 8989 which was the report of a review of Privy Councillors provided to Ministers. In many other jurisdictions, including France and the Netherlands, there is no blanket prohibition on the admission into evidence of intercept material. The 2016 Act superseded the law found in the Regulation of Investigatory Powers Act 2000, which itself replaced the Interception of Communications Act 1985. Major changes between the current regime and the one established in the 2000 Act concern the new regulatory and supervisory system established by the 2016 Act. The law relating to admissibility of intercept material, and the definition of what is and is not intercept material also changed in important ways.
The essential point before the Court of Appeal was the submission, rejected by the judge, that the EncroChat material is intercept material and inadmissible in criminal proceedings because of section 56 of the 2016 Act, and further that it was unlawfully obtained under a Targeted Equipment Interference warrant, when its obtaining should have been identified as a kind of interception which would require a Targeted Interception warrant. Targeted Equipment Interference warrants are governed by Part 5 of the 2016 Act and may produce material which can be used in evidence. Targeted Interception warrants are governed by Part 2 of the Act and the product is inadmissible in evidence in almost all criminal proceedings, including these. The judge found that the EncroChat material in this case was obtained under Part 5 warrants. These were approved by Sir Kenneth Parker, a Judicial Commissioner, on 5 March 2020, and Sir Brian Leveson, the Investigatory Powers Commissioner, on 26 March 2020, prior to the obtaining of the EncroChat material. The second warrant was needed in order to widen the scope of the first for reasons which are not material to the issues before us. The issue is whether that approach was correct, or whether on a true understanding of the way the data were obtained, and of the 2016 Act, they comprised material obtained unlawfully under the wrong warrant and, in any event, were inadmissible.
The key question was whether at the relevant time the communications were “being transmitted” or were “stored in or by the telecommunication system.” The judge found the latter to be the case. The EncroChat messages were properly regarded as falling within section 4(4)(b) of the 2016 Act and they had been obtained in accordance with a Targeted Equipment Interference warrant. He decided that for the following reasons:
The Court held:
“We agree with the judge. The communication is that which is transmitted. What remains on the device is not what has been transmitted, but a copy of it or what, in older forms of messaging, might be described as a “draft”. That is so however quickly after transmission the obtaining of the copy takes place, or even if the copy is extracted while the original encrypted communication is being transmitted. The fact that what was obtained was an unencrypted message, means that what was on the phone, and what was intercepted, was not the same as what had been transmitted because what had been transmitted was encrypted. It cannot therefore have been “being transmitted” when it was intercepted: it can only have been “being stored”.
That being so, the harvesting was interception but was rendered lawful by the Targeted Equipment Interference warrants issued under section 99 of the Act.”
and that:
‘We have concluded that the only substantial question which the judge was required to answer was whether the EncroChat material was stored by or in the telecommunications system when it was
intercepted. Like him, we consider that these communications were not being transmitted but stored at that time. That being so, the appeal is dismissed.”
We ensure we keep up to date with any changes in legislation and case law so that we are always best placed to advise you properly.
