Chowdhury v Secretary of State for the Home Office & Ors

4 March 2024
[2024] EWHC 844 (KB)
High Court
Someone sued MI5, MI6, and GCHQ for their personal data. The government agencies said national security stopped them from giving it up and showed the judge certificates proving this. The judge agreed and threw out the case.

Key Facts

  • Defendants applied to strike out the claim or grant summary judgment.
  • The hearing was initially requested to be held in private but was ultimately held in public.
