Summary
Background
A Maine corporation that produces and sells natural gas in Kentucky sued to stop the Kentucky Public Service Commission from investigating wholesale contract rates. The company sold gas by separate contracts to three local distributors, some holding municipal franchises. The Commission issued a May 29, 1937 order requiring the company to appear, produce records, and justify its rates. The company pleaded that it was not a public utility, that rate regulation would violate due process, equal protection, and its contracts, and that preparing for the hearing would cost about $25,000. It obtained a temporary restraining order and filed this suit in federal court seeking an injunction to stop the investigation.
Reasoning
The Supreme Court considered whether the federal court could intervene. It held the Johnson Act did not bar relief because the Commission's order was issued without a full notice and hearing. The federal court had jurisdiction because the claimed cost exceeded $3,000. But the Court ruled that the mere expense of preparing for an investigation, even if substantial, was not the kind of irreparable harm that warrants stopping a state agency in equity. The Court emphasized respect for state procedures, the availability of state remedies, and weighed conveniences against federal intervention, concluding equity should not block the Commission at this stage.
Real world impact
As affirmed, the state commission may proceed with its fact-finding and potential rate-making process. The company must decide whether to comply with the investigation or risk fines and criminal penalties under state law. Because no final rate order was entered, this ruling does not finally resolve whether the Commission may change rates, but it makes it harder to get a federal injunction based solely on anticipated compliance costs.
