Investigation of the Department of National Defence’s refusal to disclose personal information of a deceased individual

Department of National Defence

A representative acting for the executor of an estate requested personal information about a deceased individual from the Department of National Defence (DND). DND determined the representative was not entitled to the information under paragraph 10(b) of the Privacy Regulations because they did not sufficiently demonstrate a connection between the information sought and the administration of the estate. While DND processed the request informally and disclosed some information under another provision of the Act, they did not clearly state the grounds for refusal. The OPC found the complaint not well-founded as the representative failed to adequately articulate and substantiate the estate's purposes and how the records would serve them.

Decision pursuant to 6.1, 2024 OIC 63

A federal institution

An institution applied for approval to decline to act on five access requests, arguing they were vexatious and an abuse of the right to access information. The Information Commissioner found that two of the requests (A-2023-00305 and A-2023-00314) were indeed an abuse of the right to access. Consequently, the Commissioner approved the institution's decision to decline to act on those two specific requests. However, the institution failed to prove that the remaining three requests (A-2023-00303, A-2023-00308 and A-2023-00310) were vexatious or an abuse of the right to access.

An institution applied to decline an access request, arguing it was vexatious, made in bad faith, and an abuse of the right to access information. The institution claimed it had fulfilled its duty to assist the requester. The Information Commissioner found that the institution had indeed made reasonable efforts to assist the requester and that the request, due to its breadth and the estimated 700,000 pages it would generate, constituted an abuse of the right to access information as it would unreasonably interfere with the institution's operations and hinder other requesters' access rights. The Commissioner granted the institution's application to decline to act on the request.
