Ada County Highway Dist. v. Idaho Public Utilities Comm’nAnnotate this Case
In October 2008, the Idaho Power Company filed an application with the Idaho Public Utilities Commission (IPUC) to modify its tariff. Some of the proposed amendments applied to the relocation of utilities facilities within public rights-of-way. The City of Nampa and the Association of Canyon County Highway Districts intervened in the proceedings, and each objected to the Company’s proposed amendments to the tariff. The IPUC approved the amendments, and Ada County Highway District (ACHD) filed a petition or reconsideration and clarification. Specifically, ACHD argued that the IPUC exceeded its authority in approving the amendments and that portions of the amended tariff were “an unlawful attempt to amend or abrogate the common law rule requiring a utility to relocate its facilities placed in a public right-of-way at its expense.” Upon review, the Supreme Court found that the IPUC exceeded its authority in determining utilities relocation within public rights-of-way. The Court set aside the amended tariff.
