The National Crime Agency of the United Kingdom (NCA ) acted lawfully when it accessed millions of intercepted messages and images from an encrypted phone network that police claim was frequently used by organized criminals, according to a ruling by Britain’s most secret court. Lawyers are requesting permission from the Court of Appeal ( Civil Division ) to challenge this ruling.

A decision by the Investigatory Powers Tribunal ( IPT ) that found the crime agency had legitimately obtained surveillance warrants to access allegedly encrypted messages sent by 9, 000 UK EncroChat phone network users is being challenged by defense attorneys.

The IPT rejected claims that the NCA had violated its obligation to be truthful by withholding important information from the separate criminal commissioner in charge of approving the crime agency’s request for copies of EncroChat messages that were intercepted in the UK during a French and French police hacking operation.

Convictions might be overturned.

The action is being taken as defense attorneys are bringing a number of distinct constitutional challenges to EncroChat’s legality in criminal proceedings.

Criminal defense attorney Thomas Schofield at No. Numerous people who have been found guilty of the most serious offenses solely on the basis of EncroChat evidence are likely to seek to have their cases overturned by the Criminal Cases Review Commission (CCRC ), according to 5 Barristers ‘ Chambers, Computer Weekly reported.

” Convictions may be overturned on a scale comparable to the Post Office scandal, which resulted in the overturning of dozens of cases due to weak computer evidence.”

There are still significant concerns about how EncroChat evidence was obtained, and it’s possible that it will finally be determined to be inadmissible as evidence in the UK, he said.

After three years of investigation, the French Gendarmerie infiltrated and gathered 115 million messages and photos from the EncroChat network in 2020, leading to more than 6,500 arrests and the seizure of roughly €900 million worldwide.

More than 1,240 offenders have been found guilty in the UK, and police have found more than 173 firearms, as well as over nine tonnes of cocaine and heroin. According to the National Crime Agency’s response to EncroChat- Operation Venetic, police had detained more than 2, 000 suspects as of August 2023.

Defense attorneys are debating whether the evidence gathered from EncroChat phones is officially allowed in criminal prosecutions as a result of the novel hacking operation, which has raised numerous legal issues in the UK and abroad.

In a decision on September 19, 2023, the IPT denied defense attorneys the right to appeal its decision that the NCA had obtained surveillance warrants legally.

Eleven defendants ‘ defense attorneys are now requesting permission to challenge the Court of Appeal’s decision immediately.

The appeal is based on three constitutional justifications:

  • Whether EncroChat’s classification of many police investigations as a” one investigation” by the Investigatory Powers Tribunal was accurate.
  • Whether the tribunal had violated the defendants ‘ human rights by obfuscating the difference between bulk warrants that were more aggressive and themes.
  • Whether the tribunal gave the National Crime Agency’s proper threat assessment that EncroChat was only used by criminals too much weight.

a second inquiry

Lawyers are anticipated to contend that the National Crime Agency was improperly given a thematic equipment interference ( TEI ) warrant to obtain EncroChat data from UK ENcroShat phone users from the French police if the appeal is allowed to proceed.

TEI warrants, which allow for the surveillance of multiple targets, may only be issued for” a single investigation” or a” single operation” under Section 101 ( 1 ) C of the Investigatory Powers Act 2016.

The tribunal determined on May 11 that the use of TEI warrants was appropriate and that this investigation into EncroChat’s unlawful use could be categorized as a second investigation.

9, 000 EncroChat phone users in the UK provided the NCA with French data.

It stated that” the fact that the material was easily divided up after being obtained and analyzed so that various aspects of the illegal behavior could be prosecuted does not diminish from the overall investigation.”

But, defense attorneys are anticipated to contend that the definition of a second operation under the Investigatory Powers Act does not apply to the numerous investigations into legal organizations that were using EncroChat phones conducted by Regional Organised Crime Units and police forces across the UK.

large warrants

Defense attorneys are also anticipated to contend that the IPT “blurred the distinction” between narrative warrants, which can be used to gather information on various targets for crime combat, and bulk warranted that only allow mass data collection for national security purposes.

The bulk warrant regime, which requires the secretary of state’s approval and simply permits data to be used for intelligence purposes, has the effect of allowing the National Crime Agency to collect mass communications data without these safeguards.

The European Court of Justice ruled that “general and uncontrolled” gathering of telecommunications traffic data cannot be justified in a democratic society and in violation of Article 8 of the European Convention on Human Rights, which safeguards the right to personal communications.

use by criminals

Defense attorneys also disagree with the National Crime Agency’s assertions that only criminals used EncroChat phones in a defined version of its 2019 Strategic Threat Assessment.

They contend that requests to examine the overall EncroChat material intercepted dataset were wrongfully denied by the tribunal.

During hearings in 2022, the IPT was presented with evidence that later investigations revealed that, of the 7, 404 UK EncroChat phones examined, 294 had never clearly shown a connection to criminal activity.

Even though it was later discovered that EncroChat was used for non-criminal purposes, the tribunal concluded on September 19, 2022, that just the information available at the time of the warrant was pertinent.

It stated that there was no evidence of non-criminal use, despite the fact that material that was discovered after the warrant was issued revealed a” little number” of cases without any indication of criminal use.

Compensation claims might be comparable to the Post Office scandal

Defense attorneys are currently contesting the admissibility of EncroChat evidence in a number of Crown Court cases.

The debate centers on whether European investigators intercepted the EncroChat messages during transmission or whether they obtained them while they were stored in phone handsets.

Electric communications intercepted during transmission are not admissible in judicial proceedings under existing UK law.

Numerous people who were found guilty exclusively based on EncroChat evidence may be able to seek redress from the Criminal Cases Review Commission if the evidence is deemed illegal, according to Schofield of No5’s Computer Weekly.

” Law enforcement organizations must make sure that the techniques they employ follow the necessary factual standards.” It is debatable whether this is the case right now, and I would n’t be shocked if EncroChat evidence challenges were successful in the upcoming months and years, he said.

In the end, convictions might be overturned on a par with the Post Office scandal, which resulted in the overturning of dozens of cases due to weak computer evidence, he said.

However, some defendants in cases that only rely on EncroChat evidence have admitted guilt in exchange for lighter sentences, and it is likely that their cases will be overturned by a steep legitimate barrier.

The court of appeal ruled that “where a defendant has entered an emphatic and intentional plea of guilty, the subsequent conviction will often be found to be unsafe” in the Post Office case.

Due to the unreliability of the evidence against them from the Post Office’s Horizon IT system, it overturned the convictions of 39 sub-postmasters who had entered a guilty plea, but it even upheld those of three subsequents.

When Crown Court proceedings had resolved the issue of whether messages intercepted by EncroChat are allowed in criminal courts, the Investigatory Powers Tribunal stated in its May 2013 ruling that it would take into account additional legal issues raised by defense attorneys, such as whether the operation violated human rights law.
