Decision pursuant to 6.1, 2024 OIC 63

Jan 1, 20242023 OIC CI 47· Indexed May 7, 2026

Decision pursuant to 6.1, 2023 OIC CI 47

A federal institution

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.
