Third Direction challenge

Documents from proceedings at the Investigatory Powers Tribunal (IPT) which led to the disclosure of a secret government policy allowing MI5 officials to authorise their agents to commit criminal acts in the United Kingdom.

The so-called ‘Third Direction Challenge’ was issued at the IPT by Privacy International and Reprieve in June 2017. During the proceedings it became clear that MI5 has had guidelines in place since at least the early 1990s to regulate the authorisation of criminality, and that the Intelligence Commissioners had been asked to oversee such activity since 2012. This entire area of intelligence practice and oversight was kept secret until the challenge at the IPT, with the Prime Minister determining at a number of separate points that to reveal even the fact of its existence would harm national security.

The substantive hearing in this challenge took place in November 2019, and the Tribunal judgment was handed down in December 2019, acknowledging that the case ‘raises one of the most profound issues which can face a democratic society governed by the rule of law.’ This judgment was the first in the IPT’s history to be based on a split view amongst the judges. The majority found largely in favour of the government, declaring that MI5 guidelines neither breach human rights law nor grant immunity to those committing or commissioning criminal acts. However, two judges published dissenting views, each arguing that there was no legal underpinning for the guidelines or policy, which were in effect outside of the law.

While the claimants moved to appeal this judgment in the Court of Appeal, the government introduced legislation to put the authorisation of criminality by the Security Services on a statutory footing. The resulting Covert Human Intelligence Sources (Criminal Conduct) Act 2021 entered the statute book in March 2021, in order to ‘make provision for, and in connection with, the authorisation of criminal conduct in the course of, or otherwise in connection with, the conduct of covert human intelligence sources.’
