Stringent UK company and data protection laws are no defence
LetterOne argued that the risk to national security in this case was derived from a "remote" chain of events – consisting of the possibility of the Russian government exerting influence over the UBOs, who would then use their shareholder rights to change the company governance so as to enable LetterOne to cause Upp, through its board or management decisions, to take significant actions that would undermine national security. According to LetterOne, this "remote" risk could be resolved by corporate change and operating restrictions such as: amended articles of association, investment management contracts and other corporate governance measures. Amongst other things LetterOne argued that the Secretary of State had failed to appreciate the lack of opportunity within the rigours of company law, and data protection laws, for the UBOs to take steps that might actually compromise national security.
In dismissing these arguments out of hand, the Court found the relevant point not to be whether LetterOne (or anyone else) would breach laws, but rather whether malign actors would exploit the connection between the UBOs and Upp in any manner of ways (such as deceit, manipulation or other forms of pressure) to, for example, get hold of personal information.
Closed and open evidence
The Court reached its judgment on the basis of the open evidence (both discussed in the judgment and disclosed to LetterOne and its lawyers). However, its findings were also supported by closed material, i.e. material which if disclosed would cause damage to the interests of national security (and thus was not disclosed to LetterOne or its lawyers). The closed material was dealt with in a separate closed judgment. We can expect this type of procedure to be used routinely in future NSIA appeals.
On the question of disclosure, Swift J handed down an earlier judgment (on 23 February 2024) in which he considered the Secretary of State’s approach to the presentation of "open gists of closed documents" ([2024] EWHC 386 (Admin)). The various gists had initially been presented to appear like the original, complete documents (i.e. giving the appearance to the reader that they were the original documents as opposed to being gists of undisclosed documents). Swift J criticised that approach and set out the steps that the Secretary of State had agreed to take in order to remove any misapprehension caused to the LetterOne group. Government lawyers then took the required steps.
Research into individual members of ISU staff not welcome
During the trial, the Court noted that LetterOne's submissions had "singled out" an individual, junior member of staff as an unsuitable decision-maker who lacked any relevant expertise. LetterOne had carried out research on that individual and a print-out of his career history from a social media profile had been produced by LetterOne when submitting that key elements of the decision-making process had been entrusted to the junior staff member.
The Court was less than impressed. As well as correcting LetterOne's position, clarifying that the individual was not the decision-maker and that there is no evidence that the individual did anything that could not be expected of a junior official working in an administrative capacity, the Court also found LetterOne's online search for his personal details to be "frivolous and vexatious".
This unfavourable view accords with the ISU's general approach not to disclose the identity of more junior members of staff on cases (except where warranted).
