This is an application for a writ of review to annul an order of the respondent court vacating a restraining order theretofore granted by it for the pur *577 pose of preserving the status quo pending an appeal The petitioners herein had commenced an action in the respondent court for an injunction, and upon the filing of their complaint made an application for an injunction pendente lite. An order to show cause was issued thereon and after a full hearing thereof the court denied petitioners’ application for an injunction pendente lite and discharged the order to show cause. Desiring to appeal from the order denying their application for a temporary injunction, petitioners then applied to the trial judge for a restraining order to preserve the status quo pending such appeal. This application was made several days after the order denying the temporary injunction and was made ex parte without any notice to the defendants in said action. The trial judge granted the application and made an order for the issuance of a restraining order upon the filing and approval of a bond in the sum of one thousand dollars. The bond was duly filed and approved, the restraining order pending the appeal issued, and thereupon petitioners perfected their appeal. Thereafter the defendants duly served and filed their notice of motion in the alternative, either to vacate the order for an injunction pending the appeal or that the bond upon such injunction be increased from one thousand dollars to ninety thousand dollars. Upon the hearing thereof these petitioners objected to the jurisdiction of that court to hear and determine the motion on the ground that it was without jurisdiction so to do. The matter was argued and submitted and the respondent court thereafter made an order vacating the injunction pending the appeal which had theretofore been issued. This last is the order which petitioners are here seeking to annul.
Respondent takes the position that the trial court, having made its order denying the application for an injunction
pendente lite,
had no power to thereafter grant such an injunction to be effective pending the appeal; that its order granting the same was void, and that its subsequent order vacating the same (which is the one here under attack) was therefore properly made. In the case of

uniformly in the holding that the right to move for dissolution or modification of such an injunction is limited to cases where the injunction was granted without notice.
(Natoma Water & Mining Co.
v.
Clarkin,
Respondent insists that the rule of the Pasadena and Pierce cases,
supra,
is applicable only to a case wherein the action has proceded in the trial court to judgment and an appeal is to be taken
therefrom,
and that it is not applicable to a case such as the one at bar wherein the appeal is to be taken from an order denying the provisional injunction prior to trial and judgment. This question has not been directly decided in this state so far as we are advised. The case of
American Trading Co.
v.
Superior Court,
As was pointed out above, the rule is well settled that a judgment or order once regularly entered can be modified or vacated by the court which entered it only in the manner prescribed by statute, and it remains to consider whether or not the statute prescribes any method by which the re-" straining order pending appeal herein might be vacated or modified by the court which granted it. The order here under consideration was made
ex parte
and without notice to the adverse party. Section 937 of the Code of Civil Procedure provides that “an order made out of court, without notice to the adverse party, may be vacated or modified, without notice, by the judge who made it; or may be vacated or modified on notice, in the manner in which other motions are made.” If there be any room for doubt' as to the applicability of this general rule to provisional injunctions which have been granted
ex parte,
we turn to section 532 of the Code of Civil Procedure, which provides that: “If an injunction is granted without notice to the person enjoined, he may apply, upon reasonable notice, to the judge who granted the injunction, or to the court in which the action was brought, to dissolve or modify the same,” and prescribes the method to be followed in making such application, which was followed herein. This provision plainly reserved to the respondent court the jurisdiction and power to vacate or modify the restraining order granted by it without notice to the defendants. Petitioners do not seriously contend that the perfection of the appeal herein had the effect of divesting that court of such jurisdiction, but they do contend that the American Trading Company ease,
supra,
is authority directly to the contrary of the conclusion here reached. In that case, as in the one at bar, plaintiff appealed from an order denying the temporary injunction and secured a restraining order pending the appeal. No separate or express notice was given to the defendants in that ease of the application for the restraining order. It was urged before this court upon a
*582
review thereof that the restraining order was void because no notice of the application therefor was given to the defendants. It appeared from the record therein that the restraining order pending appeal was granted on the same day that the court directed the entry of an order denying the application for an injunction
pendente lite
and before the entry thereof. The court in its opinion did not expressly refer to this fact, but said that the jurisdiction of the trial court to make the restraining order could be sustained only “on the theory that the order granting the injunction pending the appeal is a portion of the order denying the injunction
pendente lite,”
and “is necessarily based upon the notice and hearing for the injunction
pendente lite,
consequently no other notice is necessary. ’ The question whether the trial court, having granted the restraining order, retained any jurisdiction to vacate or modify the same, was not there involved. The opinion as originally filed therein contained the statement that “if in the judgment of the petitioner the bond given by the appellant was insufficient to protect it, application should be made to the trial court for relief in the premises.” Thereafter the opinion was modified by striking this sentence therefrom. This modification is not to be regarded as a determination or indication on the part of this court that no power remained in the trial court to grant such relief, but merely that this question was not involved in that case. Petitioners contend that inasmuch as they have, in reliance upon the order of the respondent court, filed a bond herein and thus incurred expense and subjected themselves to liability, and thus procured the restraining order here in question, that the respondent court should be held to be precluded from either vacating or modifying the restraining order, upon principles analogous to estoppel. They cite as authority for this contention the cases of
