Monette Road Improvement District is, as its name implies, a road improvement district formed for the purpose of improving certain roads, *173and was created by a special statute enacted by the General Assembly of 1919 (Act No. 58, Acts 1919, Regular Session, volume 1, page 105).
Application is made to this court on behalf of said district for a writ of prohibition directed to the Honorable R. H. Dudley as judge of the second division of the circuit court of the Second Judicial Circuit to prevent the circuit court of Craighead County, Lake City District, from hearing and determining a certain proceeding brought up to that court on certiorari, issued by said judge, and returnable to said circuit court, involving the validity of the acts of the commissioners of said district in assessing benefits and in attempting to construct the improvement.
It is alleged in the petition filed here that Alex McDonald and certain other persons filed their complaint in said circuit court, praying for a writ of certiorari directed to the commissioners of said district to bring up the assessment of benefits made by the commissioners and to quash the same, and to enjoin the commissioners of the district from proceeding with the construction; that the circuit court is entirely without jurisdiction in the premises and that the petitioners appeared in court and moved to dismiss the proceedings for want of jurisdiction, but that the court overruled said motion and proceeded to issue a writ of certiorari as prayed for by the plaintiffs in that cause, and made it returnable at the next term of that court, and that the judge also issued a restraining order to prevent the petitioner and the commissioners of the district from proceeding with the work of improvement. A copy of the complaint in the proceedings below and the other pleadings are exhibited with the petition.
The circuit judge appears here by counsel and files a response in which he admits that he has issued the writ of certiorari, as alleged, returnable to the circuit court, but denies that the writ was heard or issued by the court or that the petitioner herein had appeared before the court for the purpose of objecting to the issuance *174and hearing of the writ, and alleges, on the contrary, that the petition for a writ of certiorari was presented to the circuit judge at chambers in vacation and was heard by him, and that the writ of certiorari and also the temporary injunction were issued by him in vacation, returnable to the circuit court to be heard by that court in term time. The judge also alleges in his response that the matters and things set forth in the complaint in the proceedings below are within the jurisdiction of the circuit court, and he denies that he exceeded his jurisdiction in granting the certiorari and injunction.
The first question which arises for our decision is whether or not prohibition is the appropriate remedy and is available to the petitioner under the circumstances of this case. The facts, when reduced to the simplest form, as bearing on this particular question are that the plaintiffs in the action instituted in the circuit court appeared before the circuit judge in vacation for the purpose of procuring the issuance of a writ of certiorari to bring up the proceedings of the board of commissioners of the improvement district, and to obtain an injunction to restrain further proceedings by the commissioners of the district until the cause could be heard in the circuit court; that the commissioners, as the representatives of the district, appeared by counsel before the circuit judge at the hearing and objected to the exercise of jurisdiction by the court, and that a writ of certiorari and also of temporary injunction was issued by the judge over the protest of the petitioner.
The scope of the writ of prohibition is too well known to be in doubt. In the recent case of Ferguson v. Martineau, 115 Ark. 317, this court quoted with approval the following statement of the law from a well-known text-writer on the subject: “The writ of prohibition is that process by which a superior court prevents an inferior court or tribunal from usurping or exercising jurisdiction with which it has not been vested by law.” Spelling on Injunctions and Extraordinary *175Remedies, § 1716; Shortt on Information, Mandamus and Prohibition, p. 436.
The last named text-writer, at the place indicated, laid down the rule as follows: “The broad governing principle is that a prohibition lies where a subordinate tribunal has no jurisdiction at all to deal with the cause or matter before it; or where, in the progress of a cause within its jurisdiction, some point arises for decision which the inferior court is incompetent to determine. But a prohibition will not lie where the inferior court has jurisdiction to deal with the cause and with all matters necessarily arising therein, however erroneous its decision may be upon any point.”
In the case of Finley v. Moose, 74 Ark. 217, we stated the same rule with reference to the office of the writ of prohibition, with the following qualification: “If the existence or non-existence of jurisdiction depends on contested facts which the inferior tribunal is competent to inquire into and determine, a prohibition will not be granted, though the superior court may be of the opinion that the questions of fact have been wrongly determined by the court below, and that their correct determination would have ousted the jurisdiction.”
So it is thus settled that where it appears that an inferior court is about to proceed in a matter over which it is entirely without jurisdiction under any state of facts which may be shown to exist, then the superior court exercising supervisory control over the inferior court may prevent such unauthorized proceedings by the issuance of a writ of prohibition. The essential thing is, that it must be shown that the inferior court is about to proceed beyond its jurisdiction, and that fact is said to be the jurisdictional one upon which the right of the supervising court to issue the writ of prohibition depends.
It is contended by counsel for the respondent that the remedy by prohibition not being an absolute one, but discretionary, the writ should be denied where there is a remedy by appeal or otherwise, even though the *176court sought to be restrained was about to proceed beyond its jurisdiction. They cite in support of their contention the case of Weaver v. Leatherman, 66 Ark. 211. This contention is based upon a misconception of the effect of the ruling' in the case just cited. If the absence of the right of appeal was essential to the issuance of a writ of prohibition, then that remedy would be entirely unavailable in any case, for under our Constitution the right of appeal is granted in all judicial proceedings. The true test is, as stated in the case already cited, whether or not the court is proceeding beyond its jurisdiction; and when that state of facts is shown to exist, the remedy by prohibition is the appropriate one. A litigant is not bound to submit to the exercise of jurisdiction not authorized by law, even though he has the right of appeal after the exercise of the jurisdiction has been consummated and has resulted in a judgment from which he can appeal. The remedy by appeal is afforded from an unjust judgment, whether it be void or merely erroneous (Pritchett v. Road Improvement District, 142 Ark. 509); but the remedy by prohibition is afforded as a protection against a wrongful attempt to exercise jurisdiction unauthorized by law. The two remedies are independent and one may be invoked where the other can not be, and prohibition may be invoked under circumstances where the remedy by appeal is available though inadequate.
Again it is urged by counsel for respondent that this is an attempt to control the action of the circuit judge, and they invoke the doctrine that the remedy by prohibition is available only to prevent the exercise of jurisdiction by a court and not by a judge. In the case of Reese v. Steel, 73 Ark. 66, we expressly left undecided the question whether or not prohibition was the appropriate remedy against judicial or quasi-judicial action of a judge in vacation, and whether or not the remedy was confined to the control of judicial action by a court. Nor is that question involved in the present case. The action of the circuit judge has, in the present case, completely accomplished its purpose in the issuance of the *177writ, and the present effort of the petitioner is to control the action of the circuit court and to prevent it from proceeding in a matter alleged to be entirely beyond its jurisdiction. It is true that in the petition filed here it is alleged that the court issued the writ and is about to hear and determine it and that the court also issued an injunction, and it is shown by the respondent that this allegation is not true with respect to the issuance of the two writs; but the facts, as shown by the petition and the response thereto, are that the writ of certiorari is returnable to the circuit court and that that court is about to proceed to an adjudication of the matters and things involved in that controversy. Now this entitles the petitioner to the remedy prayed for here, .unless other grounds appear for the denial of the remedy.
The response raises the question of the right of the petitioner to this remedy without first appearing before the circuit court and objecting to the exercise of jurisdiction. It is conceded that the petitioner appeared before the circuit judge and made objection to the exercise of jurisdiction, and that the judge overruled the objection. It appears from the exhibits to the pleadings here that the circuit judge made a written order expressing his opinion that the circuit court had jurisdiction to entertain the proceedings, and in his response here the learned judge adheres to his conclusion that the circuit court has jurisdiction of the cause. But it is insisted that the petitioner must first appear before the court itself and make the protest there in term time., notwithstanding the ineffectual protest before the judge who granted the writ and who is the presiding judge of that court. This court in many decisions has adhered to the rule that as a matter of practice a writ of prohibition will not be issued, unless objection to the exercise of jurisdiction is made to the court in which the proceedings are pending. Reese v. Steel, supra.
The court has never had occasion to state the exceptions to that rule, or to declare whether or not there are in fact any exceptions. It has been decided here, *178however, that the form of. the exception is immaterial, and that any sort of plea to the jurisdiction of the court will justify the issuance of a writ of prohibition. State ex rel. Butler v. Williams, 48 Ark. 227.
In Ruling Case Law, volume 27, the following is stated to be the rule of procedure established by the authorities: “As a general rule, a writ of prohibition will not be issued to an inferior court unless the attention of the court whose proceedings it is sought to arrest has been called to the alleged lack of jurisdiction, the foundation of the rule being the respect and consideration due to the lower court and the expediency of preventing unnecessary litigation. This requirement is made by rule of court in some jurisdictions. The objection in the lower court can not be said to be jurisdictional, and the higher court may and will proceed without such objection in proper oases. The rule is one of discretion only, and is not in any sense rigid or arbitrary. Thus no objection in the court sought to be prohibited need be made where the proceeding is ex parte, and there was no opportunity to object;, where the applicant was prevented by artifice or fraud from making objection; where the lack of jurisdiction is apparent on the face of the proceedings; where the intention of the inferior court to act beyond its jurisdiction is made apparent in any way and it is obvious from the whole proceedings . that such an application would be futile; or where the necessary delay would be highly injurious to the interests of the applicant. The matter of judicial courtesy should yield to the substantial personal rights of litigants, such as a sacrifice to their liberty. ’ ’ Numerous authorities are cited in support of the rules thus stated.
Particular attention is called to that part of the foregoing statement of the law to the effect that the objection to the exercise of jurisdiction by the lower court is not a jurisdictional fact upon which the power to issue a writ of prohibition depends, but is merely a rule of discretion. This, we think, is the correct view of the *179matter and it will necessarily follow, under this rule, that where it is obvious that an objection made to the court itself would be futile and would result in unnecessary or hurtful‘delay this ought to and does form an exception to the general rule of discretion that, before a writ of prohibition can be asked for, objection to' the exercise of that jurisdiction must be made to the court. This exception is well sustained by the authorities. See case note to St. Marys v. Woods, 21 Am. & Eng. Ann. Cas., p. 168; Charleston v. Littlepage (W. Va.), 51 L. R. A. (N. S.) 353; State ex rel. v. Alloe, 151 Mo. 1; State ex rel. v. Bright, 224 Mo. 514; Havemeyer v. Superior Court, 84 Cal. 397.
In the case of the State ex. rel. v. Bright, supra, the Supreme Court of Missouri, after having noticed the fact that it was not shown that any exceptions had been made to the lower court, said that the appearance of the judge in that court joining with the parties to the litigation in affirming the right of the court to proceed with the case rendered it unnecessary for the petitioner to appear before the court for the purpose of challenging the jurisdiction. This rule was, in effect, applied by our court in the case of Russell v. Jacoway, 33 Ark. 191. In that case an election contest over the removal of the county seat was involved, and the circuit judge granted in vacation a writ of certiorari to bring up the proceedings in the county court for review and the adverse parties appeared before the circuit judge and opposed the application for want of jurisdiction of the subject-matter. It was not shown that there was any objection made in the circuit court, but this court granted the writ of prohibition and vacated the writ issued by the circuit judge. We think that this rule is founded on sound reason, for it only affects the discretion of the court and is at most only a rule of practice. Why then should the petitioner be required to go before the circuit court to make an objection to the exercise of jurisdiction where it is morally certain that the objection would be unavailing? Since the circuit judge has delib*180erately overruled an objection to tbe jurisdiction and comes into this court now maintaining that the court over which he presides and before which this cause will come on for hearing, unless restrained, has jurisdiction of the subject-matter, there is no ground for assuming that he will change his mind and sustain the objection to the jurisdiction when the circuit court convenes. Our conclusion therefore is that the petitioners are entitled to a writ of prohibition, if as a matter of fact the circuit court is about to proceed beyond its jurisdiction, and that is the next question to which we will address ourselves.
The statute creating the district contains a provision in section 14 that the “construction cost of the improvements of the road herein called for, not including interest on borrowed money, shall not exceed in cost thirty per cent, of the values of all lands and real estate and real property in the district, as shown by the last county assessment,” and the question was brought to this court for decision, whether or not this applied to the last county assessment preceding the passage of the statute or to any county assessment made prior to the assessment of benefits, and we decided that it applied to the assessment preceding the passage of the statute. Watson v. Boydstun, 141 Ark. 184. It was shown in that case that the cost of the construction would exceed thirty per cent, of the values of lands according to the county assessment, and the General Assembly at the special session in January, 1920, enacted an amendatory statute raising the limitation to forty per cent, of the assessed value of the property, instead of thirty per cent., and amending the statute creating the district in other respects. The statute, as a whole, describes the boundaries of the district, the route of the roads to be improved, names the commissioners and the authority to construct the improvement, to borrow money and collect assessments on the benefits accruing to the lands, and provides for a board of assessors to value the anticipated benefits, and the filing of the list of assessments with the county clerk *181and the publication of notice of the time and place of the meeting of the commissioners for the purpose of hearing complaints against said assessments.
Section 13 provides that “any party who may have complained in writing of any of said assessments of benefits or damages, and who feels aggrieved by the action of the commissioners after the hearing herein provided for; any other person whomsoever who may have any objections to any assessment of benefits or damages, or to any other proceedings under this act or action of the commissioners, shall file his complaint thereof in the chancery court having jurisdiction within ten days after the hearing by the commissioners herein provided for, and any party not complaining within that time shall be deemed to have waived any objections that he may have to any of said assessment of benefits or damages, and shall not be heard to complain in law or equity thereafter. ’ ’
The complaint in the proceedings sought to be prohibited alleges, in substance, that the assessment of benefits had been made and filed with the county clerk and notice thereof given, and that all of the plaintiffs in that proceeding had appeared before the board of commissioners herein named and objected to the alleged assessments on the ground that no valid assessment had been made as provided by the statute; that the assessment list was ‘ ‘ a mere jumble of words and figures and to a great extent meaningless,” and that it is unintelligible. It is further alleged that the plans adopted by the commissioners contemplate two sets of improvements, one a drainage system and the other the construction of the roads, which would require two separate assessments. Various other matters are alleged in the way of threatened proceedings by the board of commissioners not authorized by the statute. The prayer of the complaint was that the plans adopted by the commissioners and the assessment list be brought to the circuit court on certiorari, and that on final hearing the same should be quashed. The prayer of the complaint was also that the *182contract for the construction of the improvement and the sale of bonds be enjoined.
It is manifest therefore from the language of the complaint that injunctive relief is sought against the proceedings undertaken by the commissioners of the district, and relief against the assessment list alleged to be inaccurate and unintelligible is sought. The injunction granted by the judge in vacation was temporary and appears to have been intended only as an incident to the relief sought in the complaint to preserve the status quo until the same could be finally heard. If the court had jurisdiction to hear and determine the cause on the facts stated and grant the relief sought, it could temporarily stay proceedings by injunction as an incident to the exercise of its jurisdiction. The real question in the case is whether or not the circuit court had jurisdiction to grant the relief sought in the complaint.
The functions of the board of assessors in assessing benefits and the board of commissioners in adjusting them on complaint of the property owners is not judicial in the ordinary sense, but it is in the nature of a legislative power. Pine Bluff Water & Light Co. v. Pine Bluff, 62 Ark. 196; Mo. Pac. Ry. Co. v. Izard County Highway Improvement District, 143 Ark. 261.
Boards created as special tribunals for certain purposes may, and sometimes do, act in a judicial or quasi-judicial capacity, and when so acting their proceedings may be reviewed on certiorari (State ex rel. v. Railroad Commission, 109 Ark. 100; Hall v. Bledsoe, 126 Ark. 125), but in the matter now before us the commissioners do not act in such capacity. The acts of the commissioners not being of a judicial or ^«.si-judicial nature, they are not subject to review on certiorari, which is limited to review of judicial or quasi-judicial proceedings. Pine Bluff Water & Light Co. v. City of Pine Bluff, supra; State ex rel. v. Railroad Commission, 109 Ark. 106. Injunctive relief is purely a matter of equitable jurisdiction, which, under the Constitution of this State, falls within the jurisdiction of separate chancery courts a3 *183now established. Article 7, section 15, of the Constitution provides that “until the General Assembly shall deem it expedient to establish courts of chancery the circuit courts shall have jurisdiction in matters of equity.” We are of the opinion that the power of the Legislature in establishing separate chancery courts therefore swept away the jurisdiction of the circuit court in matters exclusively cognizable in courts of equity.
Counsel for respondents rely upon the statute (Kirby’s Digest, section 3966), which provides that “the judge of the circuit court may grant injunctions and restraining orders in all oases of illegal or unauthorized taxes and assessments by county, city or other local tribunals, boards or officers.” This statute, however, antedated the adoption of the Constitution of 1874 and the establishment of separate chancery courts pursuant thereto, and it is not effective now, for the purpose of retaining in the circuit court matters exclusively cognizable in equity, for the jurisdiction transferred to courts of chancery in the establishment thereof was such jurisdiction as the courts of chancery properly exercise at the time of the adoption of the Constitution. German National Bank v. Moore, 116 Ark. 490. This transfer of equity jurisdiction to separate chancery courts was complete and left no vestige of that jurisdiction in the circuit courts. Such was the interpretation given by this court in the case of Merwin v. Fussell, 93 Ark. 336, where we said: “And under these provisions of the Constitution and the statute a citizen and taxpayer has the right to obtain from a court of equity an injunction against the collection of an illegal or unauthorized tax.” See also Moody v. Lowrimore, 74 Ark. 421; Harrison v. Norton, 104 Ark. 16.
The framers of the statute creating this improvement district might have provided, as has been done in many similar statutes, for appeals from the board of commissioners to the county court and thence to the circuit court, which would have given the circuit court the *184jurisdiction to review the assessments. But that was not done in the framing of this statute, which provides for proceedings in a court of equity, to be begun within a specified time. It clearly falls legitimately within the ordinary equity jurisdiction, because the assessments constitute a lien on real estate. We are of the opinion, therefore, that since the statute provides for no review of assessments by the circuit court on appeal, and, on the contrary, provides exclusively for relief in the chancery court, there is no authority for review by the circuit court on certiorari.
Counsel also rely on the decision in Pritchett v. Road Improvement District, supra, as sustaining their contention, but in that case it was void orders and judgments of the county court which were reviewed by the circuit court on certiorari.
In the case of Merchants’ Bank v. Fitzgerald, 61 Ark. 607, Mr. Justice Battle, speaking for the court, concisely defined the office of the writ of certiorari, as follows : “ (1) Where the tribunal to which it is issued has exceeded its jurisdiction; (2) where the party applying for it had the right to appeal, but lost it through no fault of his own; and (3) in cases where it has superintending control over a tribunal which has proceeded illegally, and no other mode has been provided for directly reviewing its proceedings.”
This being true, the circuit court has no jurisdiction over the subject-matter set forth in the complaint filed in the proceedings below. The court being without jurisdiction, prohibition is the appropriate remedy to stop further proceedings. The writ of prohibition is therefore awarded in accordance with the prayer of the petitioner to prevent the circuit court from further proceeding in the matters under consideration.
