Pursuant to an investigation, decision and order of the Public Utilities Commission a carrier brought an action against a shipper to recover undercharges. Based upon *117 a stipulation of facts entered into by the parties, judgment was entered for the shipper. The question presented on this appeal is whether the Public Utilities Commission in the name of the People may maintain an independent equitable action to vacate the judgment on grounds of extrinsic fraud or mistake and lack of jurisdiction in the court to render the judgment.
The carrier, respondents Ryerson and Phillips, doing business as partners under the name of Phillips Trucking Company, (hereinafter referred to as Phillips), operates as a radial highway common carrier (Pub. Util. Code, § 3516) and highway contract carrier (Pub. Util. Code, § 3517) pursuant to permits issued by the commission, 1 and as such is subject to the applicable minimum rate tariffs and regulations promulgated by the commission including a regulation known as Item 85-A of Minimum Rate Tariff No. 2. Item 85-A provides in substance that before a shipment in multiple lots may qualify for a single shipment rate, the entire shipment must be available and tendered at one time, a single shipping document must be issued prior to or at the time of the first pickup, and the entire shipment must be picked up within two days, exclusive of holidays.
In 1958, the commission commenced an investigation into the operation and practices of Phillips. Following a public hearing it rendered its decision on September 18, 1958, finding, inter alia, that Phillips undercharged respondent American Cement Corporation, (hereinafter referred to as American) by charging multiple lot shipment rates for certain shipments in 1957 without issuing shipping documents in conformity with Item 85-A. The commission directed Phillips to examine its records for the entire period from January 1,1957, to the effective date of the order to determine whether any additional undercharges occurred during that period and to take such action as may be necessary to collect them, as well as those specifically found by the commission. Pursuant to that decision and order, Phillips filed an action against American to declare the rights of the parties under the commission’s *118 decision and order and prayed that the court adjudge American to be indebted to Phillips for a certain sum undisclosed by the pleadings in this case. American answered denying the undercharges and cross-complained for a decree “that said manifest freight bills of plaintiff be reformed to express the true agreement of the parties.” Phillips and American thereafter filed an agreed statement of facts in which it was stipulated that “plaintiffs by mistake issued manifest freight bills which did not show the true agreement between the parties insofar as the same were not in accordance with the requirement of said Item 85-A that plaintiffs issue a single shipping document for each shipment of multiple lots. ’ ’
Pursuant to the stipulation the court entered its judgment on October 14, 1960, decreeing that there was no duty owing from American to Phillips under the decision and order of the commission and that the freight bills issued by Phillips be “reformed to show that they were issued under single shipping documents complying with the applicable rules and regulations” of the commission.
On August 16, 1961, the Public Utilities Commission, in the name of the People, filed the present action to vacate the judgment.
In addition to the foregoing facts, the complaint as amended alleged that there was no mistake in the issuance of freight bills by Phillips, that the stipulation and judgment were collusive, that no notice was given to the commission of the stipulation as proposed or as entered, and that the court lacked jurisdiction to render the judgment by virtue of section 1759 of the Public Utilities Code. Section 1759 provides in substance that no court, except the Supreme Court, shall have jurisdiction to review, reverse, correct or annul any order or decision of the commission or to interfere with the commission in the performance of its official duties.
Following an order sustaining a general demurrer to the complaint as amended, with leave to amend, the People declined to further amend and submitted to the court a judgment of dismissal, which was duly signed and entered. 2 This is an appeal from that judgment.
*119 The People seek to have the judgment in the undercharge action vacated on two independent grounds: (1) that the judgment was obtained by extrinsic fraud or mistake and (2) that the court lacked jurisdiction to grant the relief decreed.
A party or one in privity with him who has been prevented from obtaining a fair adversary hearing through extrinsic fraud or mistake may bring an equitable action to vacate the judgment.
(Olivera
v.
Grace,
Respondents contend that the People do not have a sufficient interest to have entitled them to intervene in the undercharge action. The interest necessary for intervention “must involve such an immediate and direct claim upon the very subject matter of the litigation that the intervener will either gain or lose by the
direct operation
of the judgment that may be rendered therein." (
Faus
v.
Pacific Electric Railway Co.,
*120
The interest of the People in maintaining the integrity of the order of the Public Utilities Commission is clearly sufficient. The collection of undercharges, as was here ordered by the commission, has been held to be one of the most effective means of preserving the minimum rate structure and of eliminating collusion between carriers and shippers.
(Gardner
v.
Rich Mfg. Co.,
Respondents contend that the People have not alleged facts showing extrinsic fraud or mistake. The complaint as amended, however, alleges that there was no mistake on the part of the carrier in issuing freight bills which did not comply with requirements of Item 85-A, that the carrier colluded with the shipper in entering into the stipulation of facts for the purpose of enabling the shipper to obtain, with respect *121 to numerous separate shipments, the benefit of the lower multiple lot rates, and that the judgment was entered on the basis of the collusive stipulation. It is further alleged that no notice was given to the commission of the proposed stipulation or of its filing with the court although its decision and order required the carrier to keep the commission informed of the progress made in collecting undercharges.
In passing upon a demurrer, those facts must be deeme'd to be true. A collusive judgment adversely affecting the rights of third persons may be set aside on the ground of extrinsic fraud.
(Harada
v.
Fitzpatrick,
We conclude that the complaint as amended alleges facts sufficient to constitute a cause of action for equitable relief on the ground of extrinsic fraud.
The People also contend that the complaint as amended alleges sufficient facts to show that by virtue of section 1759 of the Public Utilities Code the court had no jurisdiction to grant the relief decreed. That section provides: “No court of this State, except the Supreme Court to the extent specified in this article, shall have jurisdiction to review, reverse, correct or annul any order or decision of the commission or to suspend or delay the execution or operation thereof, or to enjoin, restrain, or interfere with the commission in the performance of its official duties, except that the writ of mandamus shall lie from the Supreme Court to the commission in all proper cases.”
*122
The judgment entered pursuant to the stipulation between the carrier and shipper is in conflict with the commission’s decision and order. The commission found that Phillips undercharged by charging the lower multiple lot rates without issuing shipping documents in compliance with Item 85-A. The judgment decreeing that there was no duty owing from the shipper to the carrier under the commission’s decision and order constituted, in effect, a judgment reviewing and annulling the order of the commission and, hence, was in excess of the court’s jurisdiction. Nor is the conflict dissipated by that portion of the decree purporting “to reform” the freight bills issued by Phillips “to show that they were issued under a single shipping document complying with the applicable rules and regulations” of the commission. The tariff regulations became a part of the contract of shipment and the applicable rates became fixed when the shipments were made.
(Gardner
v.
Rich Mfg. Co.,
To hold that the shipping documents can be “reformed” on the facts set forth in the stipulation and in the manner decreed would not only nullify the decision and order of the commission but would virtually render ineffective Item 85-A of the tariff regulation. For the foregoing reasons, the judgment was in excess of the court’s jurisdiction
(Pratt
v.
Coast Trucking Co.,
Although a court may have jurisdiction of the subject matter, if it grants relief in excess of its power, the judgment
*123
is subject to a direct attack.
(City & County of San Francisco
v.
Superior Court,
It is our conclusion that the complaint as amended alleges facts sufficient to constitute a cause of action for equitable relief on grounds of extrinsic fraud and lack of jurisdiction.
The judgment is reversed.
McCabe, P. J., concurred.
Respondents’ petition for a hearing by the Supreme Court was denied May 18, 1966.
Notes
The terms “highway contract carrier”, “radial highway common carrier” and “highway common carrier” have been described as follows: “A 1 highway contract carrier’ is not a public carrier, but both a ‘radial highway common carrier’ and a 1 highway common carrier’ are common carriers, the difference being that the radial common carrier does not, while the highway common carrier does, operate between fixed termini
or
over a regular route.”
(Talsky
v.
Public Utilities Com.,
Pursuant to a motion by respondents herein on May 25, 1962, the judgment of dismissal was vacated by the trial court. The People appealed from the order granting the motion and this court reversed and directed the entry of an order denying the motion to vacate, thus reinstituting the judgment of dismissal. (People v. Ryerson, et al., 4th Civ. No. 7153.) (January 22, 1964.)
In 1963 the Legislature added section 2100, relating to common carriers generally, and section 3800, relating to highway carriers, to the Public Utility Code. They provided in part that whenever the commission, after a hearing, finds that a carrier has undercharged, the commission "shall require the carrier to collect the undercharges involved and may impose upon the carrier a fine equal to the amount of such undercharges. ’ ’
