EncroChat hearings delayed as lawyers seek disclosure on police hacking

by Emma

Court hearings into the EncroChat encrypted phone network compromised by French police have been delayed after lawyers requested prosecutors to disclose further evidence of law enforcement’s ability to decrypt communications.

The National Crime Agency (NCA) has made more than 1,550 arrests under Operation Venetic after the French Gendarmerie harvested millions of supposedly secure messages from the EncroChat crypto phone network, which police say was used by criminal groups.

EncroChat hearings delayed as lawyers seek disclosure on police hacking

Defense lawyers have argued that the disclosure of evidence has been made more difficult because disclosure officers do not understand the technical detail in documents relating to police hacking of the EncroChat encrypted phone network.

The courts are preparing to hear up to a dozen preparatory hearings that will decide on the lawfulness, admissibility, and reliability of material retrieved from the EncroChat network. These decisions will be binding on future prosecutions.

The NCA has not disclosed details of how many people have been charged under Operation Ventetic, the UK’s response to the takedown of EncroChat. Still, it is understood that around 450 defendants are contesting their prosecutions across the UK.

Issues impact on multiple cases

Jonathan Kinnear QC oversees the national strategy for all 250 prosecution cases in the UK – including dealing with legal challenges to the admissibility of EncroChat evidence – for the Crown Prosecution’s Organised Crime Division.

Speaking at a preparatory hearing, he said prosecution lawyers were working to process requests for discovery from defense lawyers.

He told a court that defense lawyers had submitted documents from public websites, some of which were marked “top secret” or “top secret strap one” in evidence.

“We have been working on a response to defense disclosure requests and re-reviewing the disclosure position for last week and this weekend,” he said.

“Given the complexity of the issues, including the technical nature of them and the sheer volume of the material involved, we have not yet completed that review. These are important issues that have an impact not just on this case, but on a significant number of other cases.”

New questions after second crypto phone hack

Defense lawyers raised new questions about the capabilities of law enforcement to decrypt live communications after Belgian and Dutch police announced they had infiltrated a second secure crypto phone network, Sky ECC.

Belgian and Dutch police disclosed during a press conference on 10 March 2021 that they had intercepted more than one billion encrypted messages from the Sky Crypto phone network and had decrypted half of them.

Defense lawyers have raised questions over whether the joint operation between the UK, France, and Holland could decrypt messages from EncroChat. If true, they argue, that would undermine facts presented in earlier court hearings.
