Campaign Against Arms Trade, R (on the application of) v Secretary of State for International Trade

A group sued the UK government for continuing to sell weapons to Saudi Arabia, saying it was ignoring war crimes. A judge looked at all the evidence (some secret) and said the government's decision was reasonable, even though some mistakes were made, because they were looking at the whole picture, and not just the bad things.

Key Facts

  • Judicial review of the Secretary of State for International Trade's July 2020 decision to continue granting arms export licenses to Saudi Arabia.
  • Challenge focused on airstrikes in the Yemen conflict and alleged breaches of International Humanitarian Law (IHL).
  • Claimants (CAAT) and Interveners (Mwatana and Oxfam) argued the decision was irrational.
  • The 2020 decision followed a previous challenge which was partially successful in the Court of Appeal.
  • The Secretary of State's decision-making process involved multiple government departments (DIT, MOD, FCDO) and relied on various sources of information, including open source reporting, the UN Panel of Experts, and NGOs (e.g., Mwatana).
  • A closed hearing was conducted due to sensitive information under the Justice and Security Act 2013.
