The sole question before us is whether or not a minute order of this court denying, ex parte and without written decision, a petition made directly to this court for a writ of mandate to compel respondent Board of Funeral Directors and Embalmers to enforce a “judgment and sentence” pronounced by such board, renders res judicata a subsequent petition for the writ, made to the superior court and containing averments and exhibits substantially identical with those of the earlier petition to this court. The parties are the same. We state unequivocally that such minute order was not intended to, and did not, constitute a decision upon the merits of the petition, and therefore is not a bar to the subsequent proceeding.
The petition made directly to this court was filed on July 2, 1941, and on July 17, 1941, was denied by the following minute order: ‘ ‘ The petition for a writ of mandate is denied. ’ ’
Thereafter and on August 15, 1941, petitioner filed in the Superior Court of Los Angeles County the second petition. An alternative writ was issued by the superior court on August 22, 1941, returnable on September 24, 1941. On the return day the superior court discharged the alternative writ and denied a peremptory writ on the ground that, as pleaded by respondents, the denial by this court of the earlier petition rendered res judicata the matters set forth in the petition to the superior court.
Petitioner (appellant herein) contends:
1. That under article VI, section 24, of the California Constitution, it is entitled to a written decision from this court, stating the grounds thereof, and that therefore the minute order of July 17, 1941, if intended as a judgment on the merits, is void. The mentioned section of the Constitution provides: “.,. . In the determination of causes all decisions of the Supreme Court and of the District Courts of Appeal shall be given in writing, and the grounds of the decision shall be stated.”
2. That this court’s denial by minute order of the earlier petition may have been intended not to constitute a judgment on the merits, but to be merely a refusal to take jurisdiction for any one or more of seven suggested reasons, including failure by petitioner to show that the matter involved was of sufficient moment to justify the court in exercising its original jurisdiction (see Cal. Const., art. VI, secs. 4, 4 ½, 5; *106 Code Civ. Proc., see. 1085; rule XXVI of Rules for the Supreme Court and District Courts of Appeal).
3. That to sustain a plea of res judicata it must be proved that the judgment or decision pleaded in support thereof was on the merits.
4. That if the plea of res judicata is sustained petitioner will be denied both a hearing and a judgment on the merits.
Petitioner’s first contention may be disposed of by stating that this court has never considered and does not now consider that its initial action in issuing or declining to issue a prerogative writ on ex parte application, constitutes such a “determination of [a] cause” (Cal. Const., art. VI, sec. 24) as to require a written decision. It is only after an alternative " writ has been issued that the matter becomes a ‘' cause, ’ ’ the determination of which, i.e., the granting or denying of a peremptory writ, requires a written decision.

In the Napa Valley case,

application was first made by an electric company to this court for a writ of review for the purpose of annulling certain orders of the

fixing the rates to be charged by the company. This court refused, without written decision, to issue a preliminary writ. Thereafter the company sought in the District Court of the United States to enjoin enforcement of the Commission’s orders, and that court dismissed the proceedings upon the ground that the controversy was res judicata. Upon appeal to the Supreme Court of the United States it was held (at p. 373 of 251 U.S., p. 313 of 64 L. Ed.) that “the denial of the petition [for writ of review, by the California Supreme Court] was necessarily a final judicial determination, . . . based on the identical rights,” and that “Such a determination is as effectual as an estopped as would have been a formal judgment ...” Also, in

v.
Railroad Commission
(1941, D.C., Cal.),
“The case of Napa Valley Electric Co. v. Railroad Commission of California . . . raised a similar question. Plaintiff sought an injunction against a rate order of the Railroad Commission of the State of California after the state Supreme Court had denied a petition for a writ of review, without an opinion. In the Napa case . . . the court held that the matter was res judicata and that the bill of complaint must be dismissed.” Limited by such exactitude of expression, it is *110 obvious that the holding does not lend itself to implications contrary to the views we entertain.
Both this court and the District Courts of Appeal have consistently declined to exercise original jurisdiction in the issuance of a preliminary prerogative writ where the circumstances were such that application for the writ could properly have been made to a lower court. Under such circumstances the petition will be denied “without prejudice to the right of petitioners to seek such relief as they may be advised they are entitled to in the proper tribunal” (see
Roma Macaroni Factory
v.
Giambastiani
(1933),
supra,
The denial shown by our minute order of July 17, 1941, of petitioner’s application for a writ of mandate must be construed to constitute simply a refusal by this court to exercise its original jurisdiction. It does not appear that any sufficient reason was shown for not making the application to the superior court in the first instance. The minute order, under such circumstances, was not intended to be and is not an adjudication upon the merits of the facts presented in the application.
This determination of the effect of our minute order of July 17, 1941, renders it unnecessary to discuss petitioner’s third and fourth contentions, set out above.
The judgment is reversed and the cause is remanded to the trial court with directions to proceed with the hearing on the return to the alternative writ.
Gibson, C. J., Shenk, J., Curtis, J., Carter, J., and Traynor, J., concurred.
Edmonds, J., concurred in the judgment.
