Secretary of State for the Home Department (Home Office)

The complainant submitted a multi-part request for specified information about British citizen naturalisation. Initially, the Home Office said it did not hold some of the information and it applied section 31(1)(Law enforcement) to part 2 of the request. During the course of the Commissioner’s investigation, the Home Office additionally relied on section 23 (Information supplied by, or relating to, bodies dealing with security matters) and section 24 (National security) in the alternative, and further sub-sections of sections 31(1) of FOIA, in relation to part 2 of the request.
