The complainant requested information relating to historical child abuse at two named Detention Centres. The Ministry of Justice (MoJ) relied on section 12(2) (cost of compliance) of FOIA to refuse the request, on the basis that it would exceed the appropriate limit to determine whether it holds the information. The Commissioner’s decision is that the MoJ was entitled to rely on section 12(2) to refuse the request. The Commissioner also finds that the MoJ complied with its obligation to provide advice and assistance in accordance with section 16 (duty to provide advice and assistance) of FOIA. The Commissioner requires no steps to be taken as a result of this decision.
