Article 4(2) and Article 4(3) of Regulation 1049/2001 provide that an institution must not release a document to the public if one of the interests set out in those provisions applies, unless there is an overriding public interest in public disclosure. The Ombudsman notes that an institution to which a request is made pursuant to Regulation 1049/2001 is required to apply the Regulation in full. This involves carrying out a full analysis to determine whether an overriding public interest in disclosure exists. The Ombudsman underlines that, in this respect, it is certainly correct for the institution to which a request for public access is made to examine arguments put forward by an applicant in relation to overriding public interests. However, the Ombudsman notes that the institution concerned should also, ex officio, carry out its own examination to establish whether there is an overriding public interest in disclosure.
