Petitioners seek a writ of prohibition to restrain the Municipal Court of the City of Los Angeles from proceeding to try petitioner Murdock for the alleged violation of certain sections of an ordinance, regulating the solicitation of contributions, which it is claimed are in conflict with the federal Constitution, Amendments I and XIV, and the California Constitution, article I, section 21. It is alleged that Murdock has been twice convicted of a violation of the ordinance, that each time the conviction was reversed by the appellate department of the superior court, that a third trial has been ordered, and that the respondent court will proceed therewith unless restrained.
The constitutionality of a statute or ordinance may be tested by prohibition on the ground that invalidity of the legislation goes to the jurisdiction of the court to proceed to try the case. (See Whitney v. Superior Court, 182 Cal. 114 [187 P. 12] ; Levy v. Superior Court, 105 Cal. 600 [38 P. 965, 29 L.R.A. 811]; Arfsten v. Superior Court, 20 Cal.App. *463269, 275 [128 P. 949]; cf. Broady v. Jennings, 70 Cal.App. 647 [234 P. 120].) This rule is supported by the great weight of authority in other states. (See eases collected in 113 A.L.R. 796, 800; 42 Am.Jur. 168.) The same principle has been applied in cases where habeas corpus has been used to test the constitutionality of an ordinance. (See In re McCoy, 10 Cal.App. 116, 124-125 [101 P. 419] ; In re Vitalie, 117 Cal.App. 553, 557 [4 P.2d 171] ; cf. Ex parte Kearny, 55 Cal. 212; Ferris, Extraordinary Remedies (1926) 83; 1 Bailey on Habeas Corpus (1913) 91-93; 25 Am.Jur. 164.) Although the right to discharge by habeas corpus is not limited to cases in which a court has exceeded its jurisdiction (see Pen. Code, §§1485, 1487; In re Bell, 19 Cal.2d 488, 492-495 [122 P.2d 22]; Portnoy v. Superior Court, 20 Cal.2d 375, 378 [125 P.2d 487]), the writ has been traditionally used for that purpose. (See In re Vitalie, 117 Cal.App. 553, 557 [4 P.2d 171].)
The view that constitutionality goes to jurisdiction has at times disturbed the courts because of the possibility that full application of the theory might render otherwise final judgments vulnerable to collateral attack, and confusion also has sometimes arisen because of a failure to understand that a court has jurisdiction to determine its own jurisdiction in the first instance. The difficulties inherent in applying the term jurisdiction in cases involving unconstitutional statutes impelled the court in the Bell case to recognize that habeas corpus may be used in certain situations to test the constitutionality of a statute whether or not there is a want of jurisdiction. (19 Cal.2d at pp. 492, et seq.) In prohibition, however, we are limited by statute to proceedings without or in excess of jurisdiction (Code Civ. Proc., §1102) and we are therefore squarely confronted with the problems referred to above.
The fact that a trial court has no jurisdiction within the meaning of the term as used in certiorari and prohibition proceedings does not mean that a judgment based upon an unconstitutional statute is open to collateral attack. In Chicot County D. Dist. v. Baxter State Bank, 308 U.S. 371 [60 S.Ct. 317, 84 L.Ed. 329], a civil case, the court declared that broad statements to the effect that unconstitutional laws confer no rights whatsoever must be taken with qualifications and that a decree based upon an assumption of validity is res judicata. (See, also, 136 A.L.R. 1032; (1942) 28 Va.L.Rev. 656-657; (1942) 27 IowaL.Rev. 315-322 and (1942) 26 Minn. L.Rev. 658-661. ) In certiorari and prohibition proceed*464ings the term jurisdiction has a very broad meaning, and a writ may be granted where the court has no jurisdiction to act except in a particular manner, even though it has jurisdiction, in the fundamental sense, over the subject matter and the parties. (Abelleira v. District Court of Appeal, 17 Cal.2d 280, 287 et seq. [109 P.2d 942, 132 A.L.R. 715] ; Hill v. Superior Court, 16 Cal.2d 527 [106 P.2d 876]; Fortenbury v. Superior Court, 16 Cal.2d 405 [106 P.2d 411].) It does not follow, therefore, that to allow prohibition in such cases will result in opening the door to collateral attack.
The Bell case correctly declares that the trial court has jurisdiction to determine whether the statute is constitutional, and the same is true as to any other jurisdictional defense. The mere assertion of a claim of unconstitutionality does not oust the trial court of jurisdiction, .because the very issue of constitutionality is one which the court has jurisdiction to determine. (See discussion, In re Bell, supra, 19 Cal.2d 488, 492.) This proposition, however, is not inconsistent with the holding that prohibition lies to restrain a court from proceeding without or in excess of jurisdiction. (See Abelleira v. District Court of Appeal, 17 Cal.2d 280 [109 P.2d 942, 132 A.L.R. 715]; Hill v. Superior Court, 16 Cal.2d 527 [106 P.2d 876].) A court has jurisdiction to determine its own jurisdiction, for a basic issue in any case before a tribunal is its power to act, and it must have authority to decide that question in the first instance. It is necessary, therefore, to challenge the jurisdiction of the trial court in that court, by demurrer, motion, plea or other objection of some kind, so that that court may preliminarily decide the question whether it has jurisdiction t.o proceed. And unless a party can show that a lower tribunal, after first determining that it has jurisdiction, is proceeding to exercise it, there is nothing for a higher court to prohibit. This obvious principle is one of the cornerstones of our system of lower and higher tribunals.
The statement in Portnoy v. Superior Court, 20 Cal. 2d 375, 378 [125 P.2d 487], that a trial court is not deprived of jurisdiction to determine the constitutionality of a particular ordinance or statute by virtue of the fact that it may decide the question erroneously, is properly applicable to this basic right of the trial court to decide the question of jurisdiction in the first instance.
When, however, the trial court has heard and de*465termined the jurisdictional challenge, and has decided in favor of its own jurisdiction, and then proceeds to act, that is, to try the cause on its merits, the situation is entirely different. It then may be properly claimed that a court without jurisdiction is purporting to exercise it. At this stage, jurisdiction to determine jurisdiction has been exercised, and the higher courts will, in an appropriate ease, restrain the lower court from acting in excess of jurisdiction (see, e. g., Greenberg v. Superior Court, 19 Cal.2d 319 [121 P.2d 713]; Abelleira v. District Court of Appeal, 17 Cal.2d 280 [109 P.2d 942, 132 A.L.R. 715] ; Jackson v. Superior Court, 10 Cal.2d 350 [74 P.2d 243, 113 A.L.R. 1422].) The petition should affirmatively allege that the challenge to jurisdiction was raised in the lower court.
Although the petition in the present ease does not affirmatively allege that the jurisdiction of the municipal court was challenged by an appropriate motion, the parties do not assert such a challenge was not made, and since Murdock has been twice tried for the violation of an ordinance which from the outset he has claimed to be unconstitutional, and the case has been set for trial a third time, it is apparent that the court has decided in favor of its own jurisdiction and is proceeding to exercise it. Moreover, although the requirement that before applying for prohibition the claim of unconstitutionality must be made in the trial court has been generally observed in practice (see Jackson v. Superior Court, supra, and Greenberg v. Superior Court, supra) the requirement that the petition must affirmatively allege compliance with the condition has not been emphasized in previous decisions of this court. Under these circumstances we have determined that it is not in the interests of justice to refuse to entertain the application because of the absence of a more complete showing in the petition.
It is not, of course, a proper case for prohibition if there is a plain, speedy and adequate remedy in the ordinary course of law. As we have seen, the constitutional challenge may ordinarily be made by demurrer or motion in the trial court. In addition, habeas corpus may be used to test the constitutionality of a statute (In re Bell, 19 Cal.2d 488 [122 P.2d 22]), and the availability of that remedy has been held to be a complete bar to the issuance of prohibition. (Leach v. Superior Court (1932), 215 Cal. 531 [12 P.2d 1].) But where, as here, the defendant cannot use habeas corpus because he *466is not being deprived of Ms liberty, he should not be refused prohibition, while awaiting trial, solely on the ground that habeas corpus would be available if he would submit to imprisonment.
The next question, therefore, is whether trial and appeal are adequate remedies under the circumstances of this case. A remedy is not inadequate merely because more time would be consumed by pursuing it through the ordinary course of law than would be required in the use of the extraordinary writ of prohibition. (Bennett v. Superior Court, 218 Cal. 153, 156 [21 P.2d 946]; Lindley v. Superior Court, 141 Cal. 220 [74 P. 765]; Agassiz v. Superior Court, 90 Cal. 101 [27 P. 49].) Experience has shown that most of the meritorious defenses are sustained and most of the unsubstantial constitutional or other objections are weeded out at the proper time on the proper showing during the trial or on appeal. These remedies are therefore considered adequate in the usual situations. If tMs were not so, then whenever jurisdiction is challenged prohibition would lie and the trial of the ease would be interrupted until the reviewing court passed upon the intermediate question and appellate courts in many cases would be - converted into nisi prius courts. (Agassiz v. Superior Court, 90 Cal. 101, 103 [27 P. 49].)
It does not follow, however, that the remedies of trial and appeal must be considered adequate in all situations. It has been held in two recent cases that these remedies did not afford sufficient relief under the circumstances there presented. (Greenberg v. Superior Court, 19 Cal.2d 319 [121 P.2d 713]; Jackson v. Superior Court, 10 Cal.2d 350 [74 P.2d 243, 113 A.L.R. 1422].) In the Jackson case an attempt was made to retry the defendants on the identical charge for which they previously had been in jeopardy. In the Greenberg case there was an indictment of an individual against whom no evidence at all was presented to the grand jury. The issue of jurisdiction was first raised in both cases by motion or demurrer in the trial court and petitioners sought prohibition only after an adverse ruling below. The disregard of the fundamental rights of the defendants in these cases was so obvious and flagrant that this court felt that the expense, effort and delay of trial in the superior court would be an unfair burden on the petitioners.
The fact that the remedies of trial and appeal were considered adequate in some eases and not in others does not *467mean that the application for the writ was arbitrarily granted in one and refused in another or that the decisions cannot be reconciled on principle. It is difficult, if not impossible, to lay down a hard and fast rule which will govern all situations, and it must be determined in each case, not only on the basis of precedent but from an examination of all the facts, whether there is an adequate remedy in the ordinary course of law. A reviewing court, in order to prevent a failure of justice, has discretion in accordance with established legal principles and practice, to determine the circumstances which justify the use of prohibition to restrain a lower tribunal from acting without or in excess of its jurisdiction. And in the exercise of that discretion it may take into consideration the desirability of the prompt settlement of an important jurisdictional question so that a multiplicity of void proceedings in other cases will be prevented.
As heretofore pointed out, petitioner Murdock has been subjected to two trials and has successfully prosecuted two appeals from judgments of conviction. We granted a hearing in this matter after petitioners’ application for a writ to restrain a third trial was denied by the district court of appeal, and, in order to secure uniformity of decision of related problems, transferred to this court the appeal in Gospel Army v. City of Los Angeles, 27 Cal.2d 232 [163 P.2d 704], in which plaintiff sought to enjoin the enforcement of the same ordinance. We should not under these circumstances, in fairness to petitioner or respondent court, refuse to decide in this proceeding the jurisdictional question involved in the criminal charges, on the ground that there is a plain, speedy and adequate remedy by trial and appeal.
We come, therefore, to the question whether the sections of the Los Angeles Charities and Relief Ordinance under which Murdock is charged are unconstitutional. In the Gospel Army case, supra, we examined this legislation and some of the basic problems here involved are answered by our decision in that case, but we did not have occasion to deal specifically with one of the sections of the ordinance under which Murdock is charged. A certain amount of repetition of our discussion in the Gospel Army case is unavoidable if we are to present in an orderly and understandable manner the issues raised by petitioners’ contentions in this proceeding.
Insofar as pertinent here, the ordinance provides that no *468person, shall solicit any contribution for any charitable purpose unless there shall be filed with the Department of Social Service written notice of intention to solicit, together with information concerning the character of the solicitation, how it is to be made, and the purpose for which the funds are to be used. (§ 44.05.)1 The department is authorized to investigate the statements made by the applicant and to issue informatiou cards setting forth such facts as may be necessary to acquaint the public with the nature and worthiness of the purpose for which the solicitation is made. (§44.03.)2 The solicitor is required to exhibit the information card and read it to the *469person solicited, or present it for his perusal before accepting a contribution. (§44.12.)3 It is incumbent upon persons soliciting contributions for charity by means of receptacles in certain specified publicly owned and controlled places to secure the express written permission of the Board of Social Service Commissioners (§ 44.09(a) )4; and anyone making such solicitations by means of receptacles in certain other places open or accessible to the public is required to file a “notice of intention” as required by section 44.05. (§ 44.09 (b).)4
The ordinance is designed to protect the public from fraud and deception in the solicitation of funds for charity and to provide the public with information from which it may determine the nature and worthiness of the charitable purpose for which the collection is made. The regulatory provisions apply to all charitable solicitations, and though collections made solely for missionary, evangelical and other religious purposes are exempted therefrom, it is clear that the intent is to regulate charitable solicitations whether or not they are part of a *470religious program. In the Gospel Army case, supra, we held that the prior restraint thus imposed does not contravene the liberties guaranteed by the First Amendment.
In Reynolds v. United States, 98 U.S. 145, 164 [25 L.Ed. 244], Chief Justice Waite, in commenting upon a statement of Thomas Jefferson concerning the meaning of the First Amendment, to the effect “that the legislative powers of the government reach actions only, and not opinions,” said: “Coming as this does from an acknowledged leader of the advocates of the measure, it may be accepted almost as an authoritative declaration of the scope and effect of the amendment thus secured. Congress was deprived of all legislative power over mere opinion, but was left free to reach actions which were in violation of social duties or subversive of good order.” Mr. Justice Roberts in Cantwell v. Connecticut, 310 U.S. 296, 303-304 [60 S.Ct. 900, 84 L.Ed. 1213, 128 A.L.R. 1352], restated the rule in clear and simple language, as follows: "Thus the Amendment embraces two concepts,—freedom to believe and freedom to act. The first is absolute but, in the nature of things, the second cannot be. Conduct remains subject to regulation for the protection of society.”
There can be no question, therefore, that a person is free to hold whatever belief his conscience dictates, but when he translates his belief into action he may be required to conform to reasonable regulations which are applicable to all persons and are designed to accomplish a permissible objective. (Gospel Army v. City of Los Angeles, supra.)
Petitioners allege that Murdock was charged with having violated sections 44.09 and 44.12 of the Charities and Relief Ordinance.
Section 44.12, requiring a solicitor to exhibit an information card to the person solicited, was approved in the Gospel Army case, supra. We held in that case that information cards issue automatically upon the filing of the required information and the payment of the four cents for each card, and that the department is without authority to with*471hold such cards when the requirements are met. What we said there disposes of petitioners’ contentions here with respect to the validity of the charge against Murdock based on this provision.
We had no occasion in the Gospel Army case, however, to give specific consideration to section 44.09 which underlies the other charge pending against Murdock. Subdivision (a) of this section makes it incumbent upon persons soliciting contributions for charitable purposes by means of receptacles in certain specified publicly owned or controlled places to secure the express written permission of the board. It is well known that religious and charitable organizations frequently use receptacles to collect money from individuals in public places. It is obvious that it would be exceedingly difficult to obtain contributions in congested areas if the solicitor had to present each person solicited with an information card. It is apparent also that it would be hard to enforce a requirement of that kind under such circumstances.
When section 44.09(a) is read in the light of these circumstances and difficulties which give rise to the necessity for the requirement of a permit when contributions are to be solicited by receptacles, sufficient standards for the issuance of such permit are inherent in and follow from the reasons requiring it. While persons solicited by means of an information card are thereby sufficiently advised to discern any unfair or fraudulent scheme, passers-by solicited by means of receptacles have no similar chance of protecting themselves. Hence, if fraud appears from the information secured from those seeking to solicit by means of receptacles, the board should decline to issue a permit. Otherwise, solicitation by this method would secure financial support that unquestionably would be denied if the solicitation were made by use of an information card which disclosed the fraud to the persons solicited. In addition to protection against fraud, the requirement of a permit to solicit charitable contributions in public places by means of receptacles, assures protection with respect to the maintenance of the public convenience and safety for it is conceivable that solicitation by this method under some conditions would interfere with the free flow of traffic. We conclude, therefore, that if subdivision (a) of section 44.09 is read, as it must be, in light of the purpose and context of the entire ordinance, on the one hand, and the peculiar circumstances attendant upon collections by means of receptacles in public places, *472on the other hand, that the denial of a permit is warranted only if the information furnished to the board discloses fraud or if the solicitation as planned would interfere with the public convenience and safety. So construed, the standards applicable to the granting of the permit are reasonable and the condition imposed by subdivision (a) does not prevent or unduly restrict the collection of funds. The requirement of the subdivision is not only reasonable but assures regulation without discrimination as to persons or causes. It may be added that the numerous other recognized methods of collecting funds are available to petitioner.
It is suggested that subdivision (a) imposes the samé restraint as did the statute condemned in Cantwell v. Connecticut, 310 U. S. 296 [60 S.Ct. 900, 84 L.Ed. 1213, 128 A.L.R. 1352], That statute prohibited solicitation of money for religious, charitable or philanthropic causes without the approval of an administrative official. The ordinance challenged in this proceeding, however, is materially different from the statute involved in the Cantwell case. The statute there condemned empowered an administrative official to appraise the facts and to withhold permission to solicit if he determined the cause was not a religious one. The court held that' to so limit the right of solicitation placed a forbidden burden upon the exercise of religious liberty.
It is clear, however, from what has been said before that the right to the permit required in subdivision (a) of section 44.09 does not depend upon a religious test. The board is not authorized or empowered to appraise the nature or worthiness of a religious cause or to deny a permit upon the ground that the cause is not a religious one. As before stated, the authority of the board is limited to regulating the issuance of permits for the solicitation of funds in the designated publicly owned or controlled places ~by means of receptacles for the sole purpose of preventing fraudulent practices and protecting the safety and convenience of the public. It is held in the Cantwell case that “a State may by general and non-discriminatory legislation regulate the times, the places, and the manner of soliciting upon its streets, and of holding meetings thereon; and may in other respects safeguard the peace, good order and comfort of the community, without unconstitutionally invading the liberties protected by the Fourteenth Amendment. . . . The general regulation, in the public interest, of solicitation, which does not involve any religious test and does not un*473reasonably obstruct or delay the collection of funds, is not open to any constitutional objection, even though the collection be for a religious purpose. Such regulation would not constitute a prohibited previous restraint on the free exercise of religion or interpose an inadmissible obstacle to its exercise.” (310 U. S. 304, 305.)
Subdivision (b) of the section relates to the solicitation of charitable contributions by means of receptacles in certain specified places not included in subdivision (a). In such eases the solicitor is required to give the “notice of intention” provided for in section 44.05. That section was approved in the Gospel Army case and for the reasons there stated the requirements of section 44.12 are valid.
Petitioners further contend that the ordinance is being unconstitutionally applied as to them. The allegations relied upon in support of this contention, however, are denied by the answer and the issues of fact thus presented will not be determined by us in this proceeding.
We conclude, therefore, that the provisions of the ordinance underlying the charges against Murdock are constitutional, and that in the absence of admitted or proven facts showing that the ordinance is being unconstitutionally applied, the alternative writ must be discharged and the peremptory writ must be denied. It is so ordered.
