delivered the opinion of the Court.
.This is an appeal, under § 266 of the Judicial Code, from an order of the District Court enjoining pendente lite the enforcement of orders of the Public Service Commission of New York prescribing maximum rates for the exchange service of the Telephone Company.
The Commission, having entered upon an investigation as to the rates charged by the Company for telephone service within^the State, on March 3, 1922, after a large amount of evidence had been taken, but before the hearings had been completed, made the two orders in question. One of these reduced temporarily, pending final determination, the maximum rates to be charged by the Company after April 1, for exchange telephone service in the City of New York. The other made a like reduc *46 tion in the maximum rates for such service in other municipalities within the State, which were divided into groups, with basic area rates in each; with a further provision that either the Company or any municipality affected might apply for modification of the classifications on or before April 15. The Company on March 29 filed its bill in the District Court against the Commission, its counsel and the Attorney General of the State, for the purpose of enjoining the enforcement of these orders, upon the ground that they were confiscatory and in violation of the Fourteenth Amendment. An application for an interlocutory injunction was heard by three judges; and the court as thus constituted on'June 12 granted an interlocutory order enjoining the defendants from enforcing the orders of the Commission pending the final hearing and until the further order of the court; the Company being required to give bond for $6,000,000 to secure the repayment to its subscribers of all excess charges paid pending the suit in the event the injunction should thereafter be dissolved. From this interlocutory order the defendants have appealed directly to this Court.
Since the argument on the appeal the Company has submitted a motion to dismiss the appeal or affirm the order of the court, upon the ground that on January 25, 1923, the Commission made final orders in the pending investigation establishing a schedule of telephone rates for the State which will yield the Company a much higher annual return, than the temporary rates whose enforcement was' enjoined. This, it is insisted,‘shows that the injunction was properly granted.

The fact that the
*47
Commission has, more than seven months after the injunction was granted, made orders allowing higher rates— whose correctness may yet be questioned in appropriate proceedings for review — upon evidence not before us, does not establish that the injunction was rightly granted under the conditions which then existed. See
Cumberland Telephone Co. v. Louisiana Commission
(D. C.),
The appellants urge, in substance, as grounds of error: That the special court of three judges had no jurisdiction to grant the injunction; that the bill contained insufficient averments of fact, as distinguished from mere conclusions; that it was prematurely filed; and that the injunction was granted upon insufficient evidence.
We conclude:
1. The specially constituted court of three judges had jurisdiction under § 266 of the Judicial Code to hear and determine the application for the injunction upon the ground of the unconstitutionality of the orders of the Commission.

2. The defendants answered the bill on the merits without questioning in any way the sufficiency or form of its averments. See

v.
United States,
3. Upon the making by the Commission of the orders in question the proceedings had reached the judicial stage entitling the Company to resort to the court for relief.
Bacon
v.
Rutland Railroad,
It was not necessary that the Company should apply to the Commission for a rehearing before resorting to the court. While under the Public Service Commission Law any person interested in an order of the Commission has the right to apply for a rehearing, the Commission ife not required to grant such rehearing unless in its judgment sufficient reason therefor appear; the application for the rehearing does not excuse compliance with the order or its enforcement except as the Commission may direct; and any change made in the original order upon the rehearing does not affect the enforcement of any right arising from the original order (§ 22). As the law does not require an application for a rehearing to be made and its granting is entirely within the discretion of the Commission, we see no reason for requiring it to be made as a condition precedent to the bringing of a suit to enjoin the enforcement of the order. See, by analogy,
Hollis
v.
Kutz,
And for like reasons, it was not necessary that the Company should have exercised the privilege granted by one of the orders of applying to the Commission for modification of the classification.
Nor did the fact that the orders of the Commission merely prescribed temporary rates to be effective until its final determination, deprive the Company of its right to relief at the hands of the court. The orders required the new reduced rates to be put into effect on a given date. They were final legislative acts as to the period during which they should remain in effect pending the final determination; and if the rates prescribed were confiscatory the Company would be deprived of a reasonable return upon its property during such period, without remedy, unless their enforcement should be enjoined. Upon a showing that such reduced rates were confiscatory the Company was entitled to have their enforcement enjoined pending the continuance and completion of the rate-making process.

4. The application for the injunction was heard by the District Court upon the pleadings and affidavits relating to the cost and value of the Company’s property, its revenue and expenses. It was not necessary that the Company offer in evidence the voluminous testimony that had been taken by the Commission on the legislative question prior to making the orders in question. The bill did not challenge the orders of the Commission on the ground, that it had acted arbitrarily, without any evidence. See
Louisville Railroad
v.
Garrett,
The District Court, after consideration and analysis of the evidence, concluded that the value of the Company’s property upon which it was entitled to a return could not be reduced much below $300,000,000, and that the rates prescribed could not possibly yield a fair return upon such valuation. It is well settled that the granting of a temporary injunction, pending final hearing, is within the sound discretion of the trial court; and that, upon appeal,
*51
an order granting such an injunction will not be disturbed unless contrary to some rule of equity, or the result of improvident exercise of judicial discretion.

v.
John Wanamaker,
And finding nothing in the record which justifies us in concluding that the District Court improvidently exercised its judicial discretion in granting the interlocutory injunction, its order is
Affirmed.
Notes
The motion, which is supported by affidavits, alleges that the annual return which will be afforded by the rates established by the final orders of the Commission will exceed by not less than-$2,000,000 the revenue afforded by the rates which were in. effect before the Comnjission prescribed the temporary rates in question, and by about $5,000,000 the revenue which would have been afforded by such temporary rates.
