The complainant requested information held by Wirral Metropolitan Borough Council (the council) relating to the Wirral Transport Museum report and communications connected to the Simplification Path Finder Pilot Board. The council provided information in response to Part 1 of the complainant’s request and refused Part 2, citing section 12 (cost of compliance exceeds the appropriate limit) of FOIA. The Commissioner’s decision is that the council breached section 16(1) of FOIA. This is because Part 2 of the request did not have a single objective reading, and the council failed to seek clarification before refusing that part under section 12 of FOIA. The Commissioner requires the council to seek clarification from the complainant as to the scope of Part 2 of the request and then issue a fresh response to that part in accordance with FOIA.
