## Facts

- Hope Natural Gas Co. sold substantial quantities of natural gas in interstate commerce to utility distributors, including an affiliated distributor.
- Complaints by municipalities and a state utility commission alleged Hope’s interstate rates were excessive and unreasonable under the Natural Gas Act of 1938.
- The Federal Power Commission (FPC) conducted consolidated administrative proceedings and issued an order reducing Hope’s interstate rates.
- In setting rates, the FPC used a cost-based rate base: “actual legitimate cost” of interstate property minus depletion and depreciation, with additions for items such as working capital and certain allowances; it gave no weight to reproduction-cost and “trended” cost estimates.
- The Court of Appeals for the Fourth Circuit set aside the FPC’s order, concluding the Commission erred by not using “present fair value” and by employing allegedly improper depreciation and cost-treatment methods.
- The Supreme Court granted review and considered whether the FPC’s rate order satisfied statutory and constitutional standards.

## Issues

1. Whether the FPC’s reduced rates were “just and reasonable” under the Natural Gas Act when the Commission used a cost-based rate base and its chosen depreciation methodology rather than “present fair value” valuation.
2. Whether the reduced rates were confiscatory in violation of the Fifth Amendment because they allegedly failed to provide a constitutionally adequate return.

## Decision

- The Supreme Court reversed the Fourth Circuit and upheld the FPC’s rate order.
- The Court held that a rate order’s validity turns on the order’s overall effect, not on the particular valuation or accounting method used to reach it.
- The Court held that the challenger bears the burden to show convincingly that the rate order is unjust and unreasonable in its consequences.
- The Court concluded the allowed rates were not confiscatory because they permitted the utility to operate successfully, maintain financial integrity, attract capital, and compensate investors for risk.
- The Court rejected the view that the Natural Gas Act or the Constitution requires any single valuation formula (including “present fair value” or reproduction-cost approaches) and approved the Commission’s discretion to use cost as a basis for depreciation allowances.

## Legal Principles

- “Just and reasonable” ratemaking is evaluated by the end result (the total effect of the rate order), not by mandatory adherence to any specific valuation methodology.
- Regulatory commissions have broad discretion to select valuation, depreciation, and accounting approaches; courts do not substitute their preferred formula if the resulting rates satisfy statutory standards.
- A rate order is presumed valid; the utility challenging the order bears a heavy burden to show the rates are unjust, unreasonable, or confiscatory in practical operation.
- Constitutionally adequate rates are those that allow the regulated company to operate successfully, maintain financial integrity, attract capital, and provide reasonable compensation to investors for assumed risks.
- If a rate order meets the statutory “just and reasonable” standard, it will generally satisfy constitutional requirements as well.

## Conclusion

The Court sustained federal ratemaking authority under the Natural Gas Act by holding that judicial review focuses on whether the rate order’s overall impact produces just, reasonable, and nonconfiscatory rates, rather than on whether the agency applied any particular valuation formula such as present fair value or reproduction cost.
