Legal Principles
Section 31 FOIA is a prejudice-based exemption requiring a causal link between disclosure and prejudice, a real and significant risk of prejudice, and a public interest balancing test.
Hogan v Information Commissioner [2011] 1 Info LR 588; Department for Work and Pensions v Information Commissioner [2017] 1 WLR 1
Public interest is assessed at the date of the request refusal.
Montague v Information Commissioner and DIT [2022] UKUT 104 (AAC); Department for Business and Trade v the Information Commissioner and Montague [2023] EWCA Civ 13
A public authority can consider the ‘mosaic effect’ – the risk of combining disclosed information with existing information to create prejudice.
Sections 58-61
Section 43(2) FOIA protects commercial interests. A causal link between disclosure and prejudice must be established, along with a real and significant risk of prejudice.
Sections 69-80
Section 21 FOIA provides an absolute exemption for information reasonably accessible to the applicant by other means.
Sections 81-90
Outcomes
Appeal dismissed.
The Tribunal found the Home Office was entitled to withhold the information under sections 21, 31(a), 31(e), and 43(2) of FOIA. The public interest in maintaining the exemptions outweighed any public interest in disclosure. The ‘mosaic effect’ and potential prejudice to law enforcement and commercial interests were key factors.
