## Facts

- The Tennessee Valley Authority (TVA), a federal agency, operated Wilson Dam and related facilities for federal purposes including navigation, flood control, and national defense-related functions, producing hydroelectric power.
- TVA contracted with Alabama Power Company to (1) purchase specified transmission and related properties, (2) buy certain real property, (3) exchange energy and sell “surplus power,” and (4) impose mutual territorial sales restrictions.
- Minority preferred shareholders of Alabama Power objected, alleging the contracts and TVA’s power program were unconstitutional and would injure the corporation.
- After internal corporate efforts failed, the shareholders filed a derivative suit in federal court against TVA, Alabama Power, and related parties.
- The district court enjoined performance; the court of appeals reversed and dissolved the injunction; the Supreme Court granted review.

## Issues

1. Whether minority preferred shareholders had standing in equity to sue derivatively to block allegedly unconstitutional corporate contracts.
2. Whether Article III permitted broad review of the constitutionality of TVA’s overall program, or required limiting review to the specific contracts presented.
3. Whether Congress had constitutional authority to generate and dispose of electric power from Wilson Dam through the challenged contracts and related acquisitions.

## Decision

- The Court held the shareholders had standing to sue derivatively in equity to prevent alleged illegal and unconstitutional transactions threatening corporate injury.
- The Court rejected estoppel defenses based on Alabama Power’s prior dealings, regulatory submissions, and delay, finding no substantial prejudice or change of position barring suit.
- The Court declined to decide abstract, program-wide constitutional questions and confined review to the validity of the particular contracts and the federal authority connected to Wilson Dam power.
- The Court upheld Congress’s authority to operate Wilson Dam for constitutional ends and to dispose of power produced as an incident of those ends, sustaining the challenged contracts.

## Legal Principles

- Minority shareholders may bring a derivative action in equity to prevent performance of allegedly unconstitutional or illegal transactions causing corporate injury, without needing to prove director fraud or classic ultra vires conduct.
- Estoppel in equity requires substantial prejudice or a material change in position; technical arguments and generalized “acceptance of benefits” rationales do not automatically bar constitutional challenges in this setting.
- Federal courts may not decide abstract constitutional questions; the Declaratory Judgment Act does not remove the Article III requirement of a concrete case or controversy.
- Courts should avoid unnecessary constitutional rulings and decide no more than required by the facts and the grounds needed to dispose of the case.
- Congress may dispose of property of the United States under the Property Clause, including electric energy generated incidentally to constitutionally authorized federal projects such as navigation and national defense functions.

## Conclusion

The Court sustained TVA’s contracts tied to Wilson Dam power by grounding the decision in Congress’s authority to operate the federal project and dispose of resulting power, while limiting constitutional adjudication to what the case required and confirming shareholder standing to challenge allegedly illegal corporate compliance with governmental demands.
