ment against appellee, United Fuel Gas Company (hereafter called United), of orders made by the Public Utilities Commission of Ohio, 46 F. Supp. 309. The facts are not in dispute. The Portsmouth Gas Company, a public utility, sells natural gas at retail to the people of Portsmouth, Ohio. It purchases its entire supply of gas from United, a West Virginia corporation. The gas is conveyed through pipelines in a continuous flow from points of production in West Virginia and Kentucky into Ohio, and there delivered to the Portsmouth Gas Company. On February 24, 1932, the City of Portsmouth, under the authority given it by § 614-44 of the Ohio General Code, established the rates to be charged to Portsmouth consumers for natural gas distributed by the Portsmouth Gas Company. This ordinance did not purport to fix the charges made by United for the gas sold to the Portsmouth Gas Company. Claiming that the rates fixed by the city were unreasonable and unjust, the Portsmouth Gas Company challenged the ordinance before the Public Utilities Commission of Ohio. The Commission found that the complaint was justified, and that reasonable and just rates should be substituted for those prescribed by the ordinance. But it also found that it could not determine such rates in the absence of proof that the charges which United exacted from the Portsmouth Gas Company were just and reasonable. The Commission ruled that the sale of gas by United to the Portsmouth Gas Company for resale to consumers in Portsmouth was a public utility service within the meaning of § 614-2 of the Ohio General Code, and that the rates to be charged for such service were subject to its jurisdiction. Accordingly, on April 18, 1935, the Commission ordered that United prepare and present "all pertinent and relevant testimony and exhibits tending to prove a reasonable and just rate to be charged by it to the Portsmouth 456 Opinion of the Court. Gas Company for the furnishing of natural gas for distribution within the City of Portsmouth, Ohio." United thereupon filed a petition for rehearing with the Commission. The petition asserted that the gas sold by United to the Portsmouth Gas Company was in interstate commerce, that the two companies were wholly independent of one another, and that the Commission therefore went beyond the power of the state in asserting jurisdiction to fix the rates to be charged for gas sold by United to the Portsmouth Gas Company. United recognized, however, the authority of the Commission to compel it to produce evidence in its possession relevant to a determination of just and reasonable rates to be charged by the Portsmouth Gas Company for gas sold to its customers. This proffer of testimony by United, which was not accepted by the Commission, is relevant to the disposition of this controversy: "It [United] does not question the right of said Commission to call upon this petitioner for such evidence and facts as may be in its possession which may show or tend to show what would be a reasonable rate to be charged for gas to the consumers in the City of Portsmouth, and it offers to furnish to the Commission such facts and evidence as may be desired, or to permit any officers or agents of the Public Utilities Commission of Ohio to ascertain such facts and evidence as may be desired from its records and books for the purpose aforesaid, but denies and protests the right or power of said Commission to fix the rates at which petitioner shall sell the gas which it transports into the State of Ohio and delivers to the Portsmouth Gas Company." On May 29, 1935, the Commission denied this petition. Its order expressly reaffirmed its previous assertion of jurisdiction to fix the rates to be charged for the sale of gas by United to the Portsmouth Gas Company.1 1 "The Commission further finds that the furnishing of natural gas by the United Fuel Gas Company to the Portsmouth Gas Company Opinion of the Court. 317 U.S. This suit to restrain enforcement of the two orders of the Commission followed. In its original bill, filed July 3, 1935, United alleged that the Commission's orders were an unconstitutional attempt to regulate interstate commerce; that compliance with the orders would entail an expenditure of more than one hundred thousand dollars in order to make the usual appraisals required in determining a rate base; that disobedience to the orders would subject United and its agents to fines of a thousand dollars a day. These allegations were denied by the Commission. But on September 23, 1935, the parties stipulated that "it will cost the plaintiff a substantial sum of money, in excess of three thousand dollars, to comply with the Commission's order." The bill was still pending at the time of the enactment of the Natural Gas Act of June 21, 1938, 52 Stat. 821, 15 U. S. C. § 717, and the relevance of that statute to the present controversy was duly set forth in an amended bill filed March 8, 1939. The suit did not come to issue for more than two years thereafter. The death of one of the members of the District Court, necessitating reargument and reconsideration of the case, may explain, at least in part, why a case of such public importance should have proceeded at such a leaden-footed pace. It was not until for resale to consumers within the City of Portsmouth, Ohio, is a public utility service within the meaning of Section 614-2, General Code of Ohio; that the rates to be charged therefor are subject to the jurisdiction of this Commission; that such jurisdiction includes the right to regulate the rate or price to be charged for such service, and that the exercise of such jurisdiction is necessary for a determination of the matters and things herein at issue before this Commission." 2 The bill was filed on July 3, 1935, and on the same day a temporary restraining order was issued by District Judge Hough. The case was submitted to a District Court of three judges on September 23, 1935, but on November 19, 1935, before it was decided, Judge Hough died. An amended complaint was filed on November 20, 1936, and a second amended complaint on March 8, 1939, to which answer was made on April 25, 1939. A third amended complaint filed on April 8, 1941, 456 Opinion of the Court. January 16, 1942, that the decree now under review was entered. The District Court held that, regardless of what the situation might have been in the absence of the Natural Gas Act, that statute deprived the Ohio Commission of power to regulate the rates to be charged for gas transported and sold in interstate commerce. And so the court enjoined the enforcement of the Commission's orders against United. The Commission contends that the issues of this case lie outside the scope of the Natural Gas Act because the Commission was concerned with the establishment of rates for the sale of gas by United to Portsmouth Gas Company prior to the effective date of the federal Act, and, more particularly, to fix rates retroactive to February 24, 1932, when the city of Portsmouth prescribed the rates for gas sold to consumers by the Portsmouth Gas Company in the ordinance which gave rise to the proceedings before the Commission. This contention, if correct, would require us to consider whether the Commerce Clause, of its own force, invalidated the Commission's assertion of jurisdiction over the rates upon gas shipped by United into Ohio. was followed on April 24, 1941, by a motion to dismiss which was denied on July 8, 1941. On July 28, 1941, an application for leave to file an answer was made; this application was granted on August 4, 1941, and an answer was filed the same day. The cause having finally been submitted, the District Court filed an opinion on October 2, 1941, finding that the plaintiff was entitled to injunctive relief. And on January 16, 1942, the decree now under review was entered. The 1942 Annual Report of the Director of the Administrative Office of the United States Courts (p. 7) discloses that "The median time which elapsed from filing to disposition of civil cases terminated in the district courts during the year 1942, which had been tried to court or jury, excluding land condemnation, habeas corpus, and forfeiture proceedings, was 10.7 months; and from issue to trial it was 6.1 months. . . . This compares with periods of 10.2 months and 5.3 months, respectively, in 1941." Opinion of the Court. 317 U.S. But we must reject the contention of the Commission. It rests upon the assumption that under the Ohio law the state Commission can retroactively fix the rates of United. For it must be borne in mind that the ultimate issue in this suit is the assertion by the Ohio Commission in 1935 of power to fix appellee's rates; that the Commission has not yet exercised the power which it thus asserted; that it has not made the inquiry and the findings which must precede the establishment of new rates; that United has not posted any bond to secure refunds it might be ordered to make; that the Commission's jurisdiction to fix United's rates was denied by the District Court in its decree of January 16, 1942; and that, so far as rates in the past are concerned, the power of the Ohio Commission (apart from any limitations imposed by federal law, whether constitutional or statutory) is dependent upon the authority possessed by it under Ohio law. To sustain the Commission on this phase of the case we would have to find that it was the law of Ohio that the Commission had power to fix rates upon gas sold by United to the Portsmouth Gas Company which would be retroactive to February 24, 1932, when the city of Portsmouth prescribed the rates upon gas sold by the Portsmouth Gas Company to its customers. Unfortunately we are not aided by a finding of the lower court on this question of state law. Since the District Court was composed of three Ohio judges, they may perhaps have taken Ohio law on this point so much for granted as not to require statement. Under ordinary circumstances we would prefer to leave to others the task of formulating local law. But this case has already been too long in the federal courts, and we do not think it comports with the public interest to remit the controversy for explicit findings by the District Court as to the power of the Ohio Commission to fix rates retroactively. The situation here is quite different from Rail |
