Idaho Power Co. v. Thompson
District Court, D. Idaho · 1927-04-28 · cited 21×
The case involved Idaho Power Co. challenging an order by the Idaho Public Utilities Commission setting rates for electric service across its system in Idaho and parts of Oregon. The company argued that the rates were procedurally flawed and confiscatory under the federal Constitution, amounting to an unconstitutional taking of property without just compensation. The court reviewed the rate base, operating expenses, revenues, and net income, finding that the overall rates produced a return of approximately 6.7% on the apportioned Idaho rate base, which was not confiscatory. However, the court held that certain specific rate schedules for charitable institutions, water heating, air heating, and irrigation were invalid and enjoined their enforcement.
