Thе plaintiff is an Indiana corporation operating as a public utility and supplies Indianapolis and the citizens thereof with water, and has so supplied them for many years. It operates under an indeterminate permit issued by the Public Service Commission of Indiana, and was so operating during the year 1932.
Early in the year of 1932, the Public Service Commission of Indiana (now the Public Sеrvice Commission, Acts of 1933, c. 93, p. 663), hereinafter referred to as the “Commission,” began an investigation of the value of plaintiff’s property and the revenue received by it, looking toward an adjustment and revision of the rates under which it was then operating, and which were being paid by the water consumers of Indianapolis. ■ Before a complete appraisal had been made by the Commission to ascertain such value, it determined that the rates in force were too high and that it was justified in making effective immediately a schedule of rates tо be and remain in effect temporarily only, or until the appraisal, etc., could be completed and a. permanent schedule adopted and made effective. This action was taken pursuant to authority given the Commission to adopt emergency rates. Burns’ Ann.St. 1926, § 12795. The temporary schedule was to become effective as of July 5, 1932.
The plaintiff was cоnvinced that if it was compelled to operate under the temporary schedule of rates thus adopted by the Commission, it would be in violation of its constitutional rights and amount to a сonfiscation of its property in violation of the Fourteenth Amendment to the Constitution of the United States. Consequently, it filed in this court a bill in equity seeking to enjoin the enforcement of the order of the Commission making effective the temporary schedule of rates. The bill was filed on the 1st day of July, 1932, in which bill the plaintiff sought and pressed its petition for an interlocutory injunction. A three-judge court was organized pursuant to section 266 of the Judicial Code, as amended (28 U.S.C.A. § 380), and heard such petition. The petition for an interlocutory injunction was denied, and the tempоrary schedule of rates became effective.
The Commission continued its appraisal and investigation, with the result that a permanent schedule of rates was adopted by it оn December 30, 1932, and by its order became effective as of January 1, 1933. This was an entirely different schedule from that against the enforcement of which the plaintiff had sought an interlocutory injunction in July, 1932. The suit in which the interlocutory injunction had been denied was still pending, however, in this court. Immediately following the entry of the order by the Commission fixing the permanent schedule of rates, under date of December 30, 1932, the plaintiff did, on the 31st day of December, 1932, file what it called an “amended and supplemental bill” in the same cause in which the interlocutory injunction had beеn denied. In its amended and supplemental bill, plaintiff sought a permanent' injunction against the enforcement of the permanent schedule of rates contained in the order of thе Commission, which became effective January 1, 1933. Such amended and supplemental bill did not seek an interlocutory injunction, but simply sought a permanent injunction against the enforcement of such order upon final hearing. Upon this state of the record, the question, therefore, naturally arises as to whether or not the three-judge court, which was organized and heard the application for an interlocutory injunction against the enforcement of the temporary schedule .of rates, continues for the purpose of determining the constitutiоnality of the permanent schedule of rates. If plaintiff had abandoned the original action, and, instead of filing its amended and supplemental bill therein, had filed an original bill in a new cause in which no temporary or interlocutory relief had been sought,
Priоr to the amendment of this section in 1925, such statutory three-judge court was required to hear the petition for an interlocutory injunction only. A single judge presiding in the final hearing could reverse thе action of the three judges upon substantially the same evidence. This apparently gave rise to the amendment. It has been held that a three-judge court is necessary only when а petition for an interlocutory injunction is “made and pressed.” See Smith et al. v. Wilson et al.,
