delivered the opinion of the Court.
This is an original proceeding in which petitioners seek relief in the nature of mandamus. Upon consideration of the petition filed by the Attorney General, rule to show cаuse issued, and pursuant thereto respondents filed their answer and supporting brief. There is no dispute between the parties concerning the facts which give rise to the questions we are called upon to determine; they are as follows:
The Public Utilities Commission in a proceeding pending before it entitled Harvey et al. vs. Harold E. Watson, Jr., entered an order which direсted said Watson “to cease and desist from all transportation of bulk cement from Boettcher, Colorado, or Portland, Colorado, to other points in the Statе of Colorado, except such transportation as may occasionally and infrequently arise as an incident of the operation of a transfer, moving and general cartage business by the respondent in the' City of Loveland and the-County of Larimer.” A petition for rehearing before the commission was denied and Watson then filed a petition for review in the district court of the City and County of Denver. Upon certification of the complete record before the utilities commission the causе proceeded to trial before the respondent judge, who at the conclusion thereof on May 23, 1956, entered *326 a so-called “Court’s Ruling,” the substance of which is not imрortant. Thereafter the Public Utilities Commission by the Attorney General filed a motion to clarify this ruling and the court, on June 20, 1956, vacated the order above referred to and entered what ■ is called a “Court’s Decision” which contained the following pertinent language:
“The Certificate of Public Convenience and Necessity in question was issued to Petitioner’s predecessor in 1930 along with a large number of other similar certificates. During the next 25 years the Commission failed to determine what the word ‘occassionаl’ meant and the Commission has never made a definition of the word ‘occasional.’ The Commission has apparently made a practical interpretation оf the word ‘occasional’ upon which the Petitioner could rely.
“The reports made by Petitioner, showing what his operations were, were before the Commission. No question was raised by the Commission or the interveners for a long period of time. The Petitioner made a large investment in equipment, conducting his business as he had in the past. To now stop him without having previously defined what ‘occasional’ means, results in denying him due process. A rehearing should be held to determine whether such transportation was ‘such businеss as Petitioner might develop.’
“There was no evidence before the Commission to show what the ■ Commission had in mind when it issued the certificate to Petitioner’s predecessor in 1930. The Commission should hold a rehearing for the purpose of permitting evidence to be introduced to show what the Commission intended to grant to Petitioner’s predecessor.
“In purporting to find what the Commission had in mind when it granted such certificates in 1930, the Commission now went outside the record and considered matters which were not before the Commission and which resulted in denying to Petitioner his property without due process of law.
*327 “In view of the above the case is remanded back to the Public Utilities Commission to hоld a hearing in conjunction with the above findings.”
The Commission thereupon filed' a “Motion for New Trial and to Vacate Judgment” which was denied September 10, 1956. In the course of thе hearing on that date the following testimony was introduced:
“The Court: Let’s find out now what they [the Commission] want. •
“Mr. Zarlengo: What the Commission wants is a final decision by the Court.
“The Court: The Commissiоn will not get a final decision; its been remanded back to them.
“Mr. Zarlengo: That is what this motion is for, your Honor; is to argue the law.
“We take the position that the Court doesn’t have any jurisdiction to remand this case.”
C.R.S. 1953, 115-6-15, governs the procedure for review of an order or decision of the Commission by the district court and provides, inter alia, the follоwing:
“* * * No new or additional evidence may be introduced in the district court, but the cause shall be heard on the record of the Commission as certified by it . . .
“Upon hearing, the district- court shall enter judgment either affirming, setting aside, or modifying the order or deсision of the Commission * * *.” (Italics ours.)
The contention of the Attorney General is that it was, and is, the duty of the district court to affirm, set aside, or modify the order of the Commission, and that the said court, and the judge thereof, refuses to do other than to remand the cause for further hearing. The Attorney General asserts in part:
“In remanding the cause back to the Commission for a rehearing, the Court, has exceeded its jurisdiction and abused its discretion. This leaves Petitioners without ‘a plain, speedy and adequate remedy’ and withоut any remedy at all. * * *
“It is not here sought to have this Honorable Court *328 command the District Court to enter judgment one way or another, but only to command the District Court to proceed to judgment, as provided by law, so that Peti7 tioners will be in a position to pursue their legal remedy, if necessary.”
On behalf of respondents it is argued that an original proceeding in the nature of mandamus is not the proper remedy, and that the “Court’s Decision” was in effect a final judgment to which a writ of error will lie.
Questions to be Determined.
First: Did the trial court exceed its■ jurisdiction in remanding the cause to the Commissiоn with directions to “hold a hearing in conjunction with the above findings?”
This question is answered in the affirmative. Council for respondents rely on
Glenwood Light and Water Co. v. Glenwood Springs,
If the trial court concludes that there is not substantial evidence to support the decision of the commission under the record as made, it is the duty of the court to set aside that decision on that very ground. The district court, under the pertinent statute, has no power to order a reheаring on a question of fact but must pass judgment on the record as presented.
Second: Was the “Court’s Decision” which directed that the cause be “remanded back to the Public Utilities Commission to hold a hearing * * *” a final judgment to which a writ of error could be directed?
This question is answered in the negative. In
Morron et al. v. McDaniel et al.,
“We have repeatedly and consistently held that: ‘If the order entered in a cause dоes not put an end to the action, but leaves something further to be done before the rights of the parties are determined,- it is interlocutory and not final. To be final it must end the particular suit in which it is entered.’ ” Numerous authorities are cited.
We think it obvious that an order which expressly directs that further hearings be held upon questions of fact cannot be said to “end the particular suit in which it is entered.”
The rule accordingly is made absolute and the respondents, the District Court in and for the City and County of Denver, and the Honorаble Edward J. Keat *330 ing, a judge thereof, are hereby directed forthwith to enter judgment affirming, setting aside, or modifying the decision of the commission in the proceedings forming the basis of this action.
