This is an original proceeding in this court to obtain a writ of prohibition to prevent the respondent from further entertaining jurisdiction of a certain injunction suit now pending in the circuit court of the city of St. Louis, over which he presides, wherein the State of Missouri at the relation of Seebert Gr. Jones, circuit attorney of the city of St. Louis, is plaintiff, and the Missouri Pacific Railway Company, the Wabash Railway Company, the Missouri, Kansas & Texas Railway Company, the St. Louis and Western Railway Company, and various other railroads in the State of Missouri, are defendants.
The petition for injunction in the said case states in substance that the defendants are railroad corporations operating under the laws of the State of Missouri, and that each of them was prior to the-day of March, 1909, a competitor of each of the other defendants in the conduct and operation of railroad business in the city of St. Louis and State of Missouri, and that a number of said defendants owned and operated parallel and competing lines of railroad. The petion then contains a list of the railroad companies which it alleged are parallel and competing lines between Kansas City and St. Louis and in the city of St. Louis, and that the other railroads named therein own and operate parallel and competing lines of railroad with each other in the city of St. Louis and in other parts of the State; that under the Constitution and laws of this State, it is the duty of each railroad company to operate and conduct its business separate and distinct from the other railroads and to compete with each other in the rates fixed and charged for the transportation of persons and property (Sec. 11, article 12, Constitution of Missouri); that it is the duty of each of the railroad companies to see that its line of railroad is “run, operated and managed separately and by its own officers and agents, and is dependent for its support on its own earnings, and that the fácil*239ities and accommodations afforded the public for travel and transportation are under fair and open competition” (Sec. 1062, R. S. 1899); that it is made the duty of the defendants by article 12, section 23, Constitution of Missouri, and section 1127, Revised Statutes 1899, to transport passengers and freight upon their lines of railroad without discrimination as to persons or localities in charges or in service; that said defendants disregarding their duty and obligation under the Constitution and laws of the State of Missouri in this regard (Constitution, article 12, section 14; article 12, section 17; article 12, section 23; sections 1062, 1127, 1128, R.S. 1899; Act of 1907, approved March 12, 1907, Laws of Missouri 1907, pages 377-382), did on the-day of March, 1909, enter into a combination and agreement to defeat fair and open competition in the management and operation of their said lines of railroad by combining and agreeing to charge, exact and receive for carrying passengers wholly within the State of Missouri and the city of St. Louis, three cents a mile. And that each and all of said defendants obligated and bound themselves by said agreement not to carry passengers at a less rate than three cents a mile within the city of St. Louis and State of Missouri; that thereafter, to-wit, on the 31st. day of March, 1909, at the city of St. Louis, said defendants and each of them, in violation of the Constitution and laws of the State of Missouri, entered into a combination and agreement to defeat fair and open competition between said defendants and each of them in the management and operation of their said lines of railroad by combining and agreeing among and between themselves whereby they agreed to carry certain passengers within the city of St. Louis and wholly within the State of Missouri who could purchase or secure from them credentials or mileage books at a less rate than three cents a mile, to-wit, at a rate of two cents a mile, for those who would purchase *240two-thousand-mile credential hooks; and to carry certain persons at a less rate than three cents a mile, to-wit, at the rate of 2% cents a mile, who would purchase five-hundred-mile mileage books, good upon all of the lines of the said defendants ’ roads; and at a less rate than three cents a mile, to-wit, at a rate of 2% cents a mile, to each person who' would purchase a five-hundred-mile mileage book good only in the hands of said book holder on the lines of such defendant road issuing such mileage book, but that said defendants and each of them at said time and place also combined and agreed among themselves, in violation of their obligation under the Constitution and laws of the State of Missouri, to conduct and operate their said railroad business for the acommodation and transportation of the general public “under fair and open competition,” that they would exact and receive from all other persons riding upon their said lines of railroad wholly within the State of Missouri and in the city of St. Louis,, who did not purchase or secure said credential or mileage books, . a charge of three cents a mile as had been previously agreed upon by said defendants as aforesaid; and that said defendants and each of them are threatening to and are about, beginning on the 10th day of April, 1909, and thereafter, unless enjoined and restrained by an order of this court, to exact and receive from such passengers upon their said lines of road in the city of St. Louis and within this State, who do not purchase or.secure such credentials or mileage books, as aforesaid, a charge of three cents a mile as a result of said combination and agreement made among said defendants as aforesaid, in violation of the Constitution and the laws of the State of Missouri, and unless enjoined they will “discriminate between passengers upon their said lines of road within the State of Missouri and the city of St. Louis by charging some of the passengers two cents a mile, some two and a half cents *241a mile, some two and one-fourth cents a mile, and some three cents a mile as a result of said combination. ”
The amended petition then alleges that under the Constitution and laws of this State, defendants are required to transport passengers for fair and reasonable charges, and that three cents a mile and two and one-half cents a mile, which defendants propose to charge or exact, “are charges unfairly and unreasonably high and are more than sufficient to give said defendants a reasonable return upon the value of their property used in said business in this State.” That the action of the defendants in carrying out the agreement and combination will work irreparable injury to the people of St. Louis and Missouri- and the public welfare, and will result in defendants receiving many thousands of dollars to which they are not entitled, “but that the amount of such unlawful, unreasonable and discriminatory charges received and exacted by said defendants and each of them from each individual passenger will be comparatively small, and that such passenger will have no adequate remedy at law, and, unless enjoined and restrained by an order of this court from carrying out the provisions of such combinaiion and agreement, and enforcing the discriminations herein described, and exacting the unfair and unreasonable charges hereinbefore described, there will result a great multiplicity of suits by passengers upon said defendants’ lines of railroad against said defendants on account of said unlawful combination and agreement and said unlawful and discriminatory charges exacted and received from said passengers by said defendants.” The petition then alleges that the railroad companies, by reason of their being incorporated and licensed to do business in this State, agreed to comply with the laws of this State, and that if the defendants are permitted to carry out their alleged combination it will interfere with the commerce and *242business of the State and obstruct and impair the operations of the lines of the railroads of the defendants, contrary to the Constitution and laws of Missouri. The petition then concludes with a prayer that the defendants may be temporarily and permanently restrained from putting the proposed rates complained of into effect and specifically enjoined from charging three cents and for charging more than two cents.
The application for prohibition in this case was presented to this court on April 30, 1909, and contains the above recited petition and amended petition in the said injunction proceedings, and also the orders made by the respondent, Judge Williams, in the said injunction case, to-wit: that upon the filing of the original petition on the 8th of April, 1909, the respondent as judge of the circuit court of the city of St. Louis made and issued a restraining order and set down the application for a temporary injunction for hearing on April 12, 1909, at ten o’clock. In the restraining order defendants were enjoined from charging, exacting or receiving three cents a mile for the transportation of passengers within the State of Missouri and from receiving a higher or greater amount than two cents a mile. It is then alleged that on the 12th of April, the hearing of the application for a temporary injunction was continued until the 23rd of April. That on the 23rd of April, 1909, the relators herein, the defendants in that injunction proceeding, filed their motions to annul and vacate said restraining order and orders, and for grounds thereof among others stated that the circuit attorney of the city of St. Louis, who brought the injunction suit, did not execute and file a bond with sufficient surety, or any bond, in favor of the defendants, as required by the statutes of Missouri; that the said circuit attorney had no authority to institute, prosecute or maintain the suit and that the said'court was without jurisdiction to entertain the cause. That the Act of 1907, approved March 19, *2431907, had no application to matters and things and business and transactions referred to and mentioned in said petition for injunction; that the subject of passenger rates was not in any manner involved in or affected by the aforesaid act; that section 17 of article 12 of the Constitution, and section 1062, Revised Statutes 1899, do not apply to or embrace the matters referred to and mentioned in the petition, and the same is true of sections 1127, 1128, Revised Statutes 1899. That on the face of the petition there is no discrimination pretended or proposed to be practiced and nothing is proposed to be done that is not proper for the railroads to do.' That the restraining order issued by the judge is in conflict with and is violative of the injunction granted by final decree in the cases brought by the railroad companies parties to this injunction suit against members of the Board of Railroad and Warehouse Commissioners, the Attorney-General and the various prosecuting attorneys of the State in the circuit court of the United States for the Western Division of the Western District of Missouri, at Kansas City, in which said cases final decrees have been rendered perpetually enjoining the railroad commissioners and others from enforcing or attempting directly or indirectly by suit or in any other manner to enforce against the railroad companies any of the provisions of or penalties provided for by the acts of the Legislature of the State of Missouri which are set forth in said motions to vacate, and from interfering with the defendants in those cases, relators herein, in restoring and putting in force the rates authorized by sections 1191, 1192 of the Revised Statutes of Missouri, the railroads having been temporarily required to adopt the two-cent rate under the order of the United States Court of June 17, 1907. That the said suit and restraining order in their effect and operation will deny to these relators the benefit of the decrees rendered and entered in their behalf in the said *244several cases in the United States Circuit Court. That the said restraining order, by limiting and confining defendants to the use of the rates and passenger fares, deprives these relators of their lawful' rights and their property without due process of law. On the 23rd of April, 1909, over the protest of relators, the hearing of said motions to annul and vacate the said restraining order was postponed until April 26th, as was the hearing on the motion filed by the Missouri, Kansas & Texas Railroad Company on that day to dismiss the cause. The other relators filed motions to dismiss that cause on the 26th of April, 1909, all of which said motions appear in the application for prohibition herein, and it may be stated generally that the grounds of said motions are that the circuit attorney had no authority to institute or maintain the suit and that the circuit court was without jurisdiction to maintain the cause and because the circuit court exceeded its jurisdiction in maintaining the same, and other grounds. On the 24th of April, 1909, on the application of the circuit attorney and without any notice to the defendants in that suit, an order modifying the former restraining order was made, which omitted the specific injunction against charging more than two cents a mile, but still restrained and enjoined the companies from charging three cents a mile. It is further stated in the application for prohibition that on the 26th of April, 1909, the respondent judge of the circuit court as aforesaid stated, when he was requested by the counsel for the relators herein to take up, consider and dispose of their said several motions to vacate said injunction and restraining orders, that he had been advised that the United States Circuit Court for the Western Division of the Western District of Missouri had made a supplementary order in the cases therein pending against the Railroad Commissioners and others, and had enjoined the circuit attorney, See*245bert Jones, and his assistants from prosecuting said injunction suit and from taking any further action therein other than to dismiss the same, or to give bond to secure damages, and to have dissolved the restraining order issued therein, and therefore that he, the said respondent judge of the circuit court of the city of St. Louis, would not hear arguments upon said motions, but would take the same and would announce his decision thereon about five o’clock on the evening of the said day; relators herein having appeared in said court, the respondent announced that he had reached the conclusion that as the suit before him was prosecuted under the Act of March 19, 1907, Laws of Missouri, 1907, pages 377-382, the State was a party plaintiff and no bond was required as a condition precedent to the granting of a temporary injunction or restraining order and the motion to vacate the said restraining order would as to the fourth ground thereof (to-wit, that the said Seebert Gr. Jones had not executed and filed in said cause a bond with sufficient surety in favor of the defendants as required by the statutes of Missouri and the said restraining order had been made in disregard and violation of the statutes in such case made and provided), be overruled, and he would continue said case and the hearing of said motions to May 15th, 1909.
Upon the filing of the petition in this cause for the writ of prohibition a provisional rule was granted and made returnable on the 13th of May. On that day the respondent filed his motion to dismiss this cause upon the following grounds: First, because, as appears by the petition, the circuit court had and has jurisdiction in said cause pending before said circuit court. Second, because, as appears from the petition filed herein by relators, the circuit court of the city of St. Louis had and has jurisdiction in the said cause pending before said circuit court to entertain said suit and make all orders therein as were made and entered in said *246causé. Third, because, the petition filed herein for prohibition was prematurely filed in that said application for prohibition was filed before respondent passed upon the motions presented by relators and while said motions were still pending. Fourth, because the petition shows upon its face that relators are charged with entering into a conspiracy to fix passenger rates in violation of the Constitution and laws of the State of Missouri, and the circuit court of the city of St. Louis has and had jurisdiction in the premises to hear the subject-matter complained' of. Fifth, because the circuit court of the city of St. Louis is a court of general jurisdiction and had and has jurisdiction over the subject-matter of the proceedings complained of by relator.
'
The petition and the motion to dismiss, which will be treated in the nature of a demurrer for the purposes of this case, sufficiently present the facts and the contentions of the two parties to enable this court to determine whether the circuit court of the city of St. Louis over which respondent presides is proceeding without jurisdiction or is exceeding its lawful jurisdiction in the said injunction case pending before it.
The office of a writ of prohibition has been defined so often in this jurisdiction that no time or space need be allotted to it, at this time, further than to say that we are required by the application for the writ and the motion to dismiss, to determine whether the circuit court of the city of St. Louis, presided over by respondent, Judge Williams, in retaining and asserting its right to make and enforce the restraining orders, already noted, against the defendants and in asserting its rights to grant perpetual injunctions in said cause, is keeping within the bounds of the jurisdiction prescribed for it by the laws of this State, for it is now the settled doctrine that the writ lies as well to prevent an excessive or unauthorized application of *247judicial force as where a court assumes judicial power not granted by law.
I. In the natural order of things, the objection presented in the third ground of the motion to dismiss should be first disposed of. It is, that this application to this court is premature because the respondent had not passed upon the motions filed by the relators or plaintiffs in the circuit court.
This contention was answered by this court in State ex rel. v. Aloe, 152 Mo. l. c. 484, in these words: “It is said by an eminent law-writer that, before the writ of prohibition should issue, it ought to appear that the party applying for it has applied in vain to the inferior tribunal for relief (High on Ex. Legal Rem., sec. 765), and that author cites in support of the proposition a decision of the Supreme Court of Arkansas which does so declare (State ex rel. v. Williams, 48 Ark. 227); but whilst we agree to that general rule, we do not apply it as the counsel who invoke it here insist. It is not a jurisdictional requirement, it is not essential like a motion for a new trial before appeal.” To a like effect is State ex rel. v. Eby, 170 Mo. 518, 521; 19 Am. and Eng. Ency. Law, 273 (note); Shortt on Prohibition, 459; Keough v. Grime, 53 N. E. 135; Havemeyer v. Superior Court, 84 Cal. 327.
But the proposition is without force in this case, for the reason that the relators here, the defendants in the injunction suit in the circuit court, did challenge the proceedings in that court, and the respondent, after overruling the motion to vacate the restraining order for the failure of plaintiff to give bond, continued the hearing on said motions over the objections of the relators, for twenty days, and that respondent is of opinion that he has jurisdiction and intends to assert it is established by the first ground of his motion to dismiss in this court in which he asserts “the circuit court had and has jurisdiction in the said cause *248pending before said circuit court.” Even if the law required a motion to dismiss the injunction in the circuit court for want of jurisdiction, it would be unreasonable to turn plaintiffs out of this court and send them back to that court merely to have a formal denial of their motion or plea entered upon its records.
II. Among other averments of the petition there is one which sets forth at length that heretofore there were pending in the United States Circuit Court for the Western Division of the Western District of Missouri, suits in equity instituted severally by the relators herein and similar suits by each of the other railroad companies named as defendants in the suit instituted in the circuit court of the city of St. Louis, hereinafter mentioned, which said several suits were entitled,’ each respectively, Railroad v. Herbert S. Hadley, Attorney-General of the State of Missouri, John A. Knott, Joseph P. Rice and Frank Wightman, Railroad Commissioners of the State of Mo., et al. (the other defendants being various prosecuting attorneys and citizens of the State of Missouri), and one of the objects and purposes of said suits in equity was to have declared null and void the statute of the State of Missouri enacted by the General Assembly of said State and approved February 27th, 1907, which act repealed section 1191 and 1192 of chapter 12 of article 4 of the Revised Statutes of Missouri, and enacted three new sections to be known as sections 1191 and 1192 and 1192a, in lieu thereof, which said act amended section 1192, Revised Statutes 1899, which limited railroad companies in class A to a charge of not exceeding three cents a mile for transportation of passengers, so as to limit railroad companies in classes A, B C to a charge not exceeding two cents a mile for the transportation of passengers, and provided that any railroad company which should violate any of the provisions of said new section 1192 should be deem*249ed guilty of a misdemeanor and upon conviction should pay a fine of not less than one hundred nor more than five hundred dollars; that due proceedings were had in said causes and the evidence heard and the same were submitted to the court and afterwards by proper 'orders and entries of record, the Honorable Elliott W. Major, Attorney-General of Missouri, and H. R. Oglesby, member of the Board of Railroad and Warehouse Commissioners of this State, were duly made parties defendants in said suits; that thereafter on the 8th of March, 1909, the said United States Circuit Court rendered final decrees in said cases as prayed, and on April 17, 1909, said decree was amended, wherein it was adjudged and decreed that the said Act of February 27, 1907, reducing the rate of transportation to two cents a mile, and certain other acts therein mentioned, were confiscatory and to compel relators to comply therewith would be to deprive them of their property without due process of law, and thereupon the Attorney-General and Railroad Commissioners and their agents, employees and servants were specifically enjoined from enforcing or attempting to enforce said acts. The court espressly retained jurisdiction of the cause to bring in any and all other parties from time to time who should attempt or threaten to take any action or institute any proceedings against relators under said statute to the end that supplemental orders or decrees might be made, and especially retained and reserved to itself jurisdiction over all the parties thereto and “all subjects-matter therein” not then covered by the pleadings. But the court did not stop with this. The decree further provides, “Some of the defendants having announced their intention to appeal, it is now ordered that no appeal shall supersede the injunctive portions of this decree, but pending any such appeal the complainants shall be permitted to charge the rates permitted by sections 1191 and 1192 of Revised Statutes Missouri, 1899, the same as *250if the Passenger Rate Act approved February 27,1907, and herein held to be confiscatory, had not been passed. Complainant having by order herein of June 17, 1907, been required to temporarily adopt the rate fixed by said Passenger Rate Act, shall be and is hereby permitted, free from the interference of the parties and classes represented by them, who are hereby ordered not to interfere, to restore and put in force the rates authorized by said sections 1191 and 1192, this court reserving the power and jurisdiction from time to time to enforce, change and modify this paragraph of this decree, as well as to protect the complainant in being restored to the right of which said order temporarily deprived it.”
The suit which this court is asked to prohibit is one brought by Mr. Jones, the circuit attorney of the city of St. Louis, against these same relators, in which it is alleged that they had combined to charge three cents a mile for passengers transported by them on their roads, and prays that the defendants therein, relators herein, be temporarily and permanently enjoined and restrained from carrying out said agreement and combination, and that they and each of them be enjoined and restrained from exacting and receiving a charge of three cents a mile for the transportation of passengers in the city of St. Louis and wholly within the State of Missouri, in accordance with said combination and agreement; and that they and each of them be enjoined and restrained from charging any passengers upon their said lines of railroad a higher or greater amount than they propose and intend to exact from any other passengers upon their said lines of railroad in this State, to-wit, the sum of two cents a mile, etc.
In short the situation presented to this court by the pleadings is that on the 8th of April, 1909, the United States Circuit Court within and for the Western Division of the Western District of Missouri, with *251jurisdiction over the parties and the suhject-matter, adjudged the rights of these relators to charge certain rates for the transportation of persons on their several roads. That is to say, the said circuit court, having by its order of June, 1907, compelled these railroads to conform to the limitations of the Act of 1907, to-wit, to carry passengers for two cents a mile, afterwards on March 8th, 1909, adjudged and decreed that the act of the General Assembly of Missouri of February 27th, 1907, was confiscatory, and if enforced would deprive the railroads of their property without due process of law, and therefore was void, and then affirmatively adjudged by its decree that the railroads should be permitted without interference by the Eailroad Commissioners of this State or the Attorney-General or other persons to return to the rates that were in force prior to the order of, June, 1907, that is, the three cent rate authorized by section 1192, Eevised Statutes 1899. Now in this condition of affairs, the circuit attorney of St. Louis, Mr. Jones, brought the proceeding for injunction in the circuit court of the city of St. Louis, over which the respondent, Judge Williams, presides, and however we may look at it, the practical purpose and scope of that suit was to perpetually enjoin the railroads from charging three cents a mile and from charging more than two cents a mile, and thus it cannot be disguised that this injunction suit in the circuit court of the city of St. Louis was brought to defeat the decree of the United States court in so far as the right of the railroad was adjudged by that court to charge three cents a mile for transportation of passengers in this State. The subject-matter of the litigation in both courts was and is the compensation which the relators shall be entitled to for the carrying of passengers on their roads wholly within this State. It must he kept in view that the proceeding in the circuit court of the city of St. Louis is to obtain an injunction against charging more than two cents a mile *252by tbe relators. This is the full scope and effect of the proceeding; it is not ancillary to some other relief which is sought for in the bill, because no other relief is demanded in the bill. While counsel speak of the' charges of illegal combination and confederacy, after all, those' charges simply go to the establishing of a conspiracy to exact and demand the three cent rate or more than two cents.
But it is urged by the respondent, Judge Williams, that the parties to the said suits are not the same. In determining who are the real parties to these actions, the purposes of the two suits must be kept in view. In a general sense in this controversy over the rates that the railroads may charge, the carriers are the parties on one side and the shippers and passengers are the parties on the other side. The officials of the State who, are requird to or who assume to conduct such litigation, represent the shippers and passengers whose interests and rights are being litigated. This is true whether the suit be brought by the carrier against public officials to enjoin the enforcement of some law claimed to be invalid or whether it be brought by the officers of the State against the carriers to enforce some law. In Reagan v. Loan & Trust Co., 154 U. S. l. c. 388, 389, it was pointed out that an action or suit like that brought by these relators against the Attorney-General and Railroad Commissioners did not infringe the constitutional right of a State to be exempt from suit without its consent. Judge Brewer, speaking for the United States Supreme Court, said: “The other class is where a suit is brought against defendants who claim to act as officers of the State and under the color of an unconstitutional statute commit acts of wrong or injury to the rights and property of the. plaintiff acquired under a contract with the State. Such suit whether brought to recover money or property in the hands of such defendants unlawfully taken by them in behalf of the State or for compensa*253tion in damages or in a proper ease where the remedy at law is inadequate for an injunction to prevent such wrong and injury or for a mandamus in the like case to enforce upon the defendant the performance of a plain legal duty purely ministerial, is not, within the meaning of the 11th amendment, an action against the State.” [Citing numerous eases.] That case is further instructive in view of the contention in this case by the respondent that the injunction in the circuit court of St. Louis is prosecuted for the State in its own right. Judge Brewer, speaking' for the court on this point, said: “So far from the State being the only real party in interest and upon whom alone the judgment effectually operates, it has in a pecuniary sense no interest at all. Going back of all matters of form, the only parties pecuniarily affected are the shippers and the carriers, and the only direct pecuniary interest which the State can have arises when it abandons its governmental character and as an individual employs the railroad company to carry its property. There is a sense, doubtless, in which it may be said that the State is interested in the question, but only in a governmental sense. It is interested in the well-being of its citizens, in the just and equal enforcement of all its laws, but such governmental interest is not the pecuniary interest which causes it to bear the burden of an adverse judgment. Not a dollar will be taken from the treasury of the State, no pecuniary obligation of it will be enforced, none of its property affected by any decree which may be rendered. ’ ’ And this same doctrine was announced in Railroad v. Missouri Railroad and Warehouse Commissioners, 183 U. S. 53; Prout v. Starr, 188 U. S. 537; Ex parte Young, 209 U. S. 123. So in these two cases; in the one in the United States Circuit Court, the State officials were enjoined from doing certain things against the relators, whereas in the other case in the State circuit court it is proposed to enjoin the railroads from demanding *254and receiving the various fares set out in the petition for this writ of prohibition. Thus we have two cases in courts of ordinary co-ordinate jurisdiction where the power of the courts is being exercised between practically the same parties in interest, to-wit, the carriers on one hand and the shippers and passengers on the other upon the same subject-matter, and the two courts are thus brought in conflict with each other.
In Covell v. Heyman, 111 U. S. 176, it was said by the Supreme Court of the United States: “The forbearance which courts of co-ordinate jurisdiction, administered under a single system, exercise towards each other, whereby conflicts are avoided, by avoiding interference with the process of each other, is a principle of comity, with perhaps no higher sanction than the utility which came from concord; but between State courts and those of the United States, it is something more. It is a principle of right and of law, and therefore, of necessity. It leaves nothing to discretion or mere convenience. These courts do not belong to the same system so far as their jurisdiction is concurrent; and although they co-exist in the same space, they are independent, and have no common superior. They exercise jurisdiction, it is true, within the same territory, but not in the same plane; and when one takes into its jurisdiction a specific thing, that res is as much withdrawn from the judicial power of the other, as if it had been carried physically into a different territorial sovereignty. To attempt to seize it by a foreign process is futile and void. The regulation of process, and the decision of questions relating to it, are part of the jurisdiction of the court from which it issues.” This is but a statement of the general doctrine where the res is brought within the custody or control of a court of one system by the levy of process, either mesne or final.
“The principle that a court which has rightfully taken jurisdiction over a subject-matter of litigation, *255and has adjudicated the rights of the parties, is bound to secure to the prevailing party the fruits of the litigation, and to that end, when necessary, by injunction or otherwise, may restrain the other party from attempting to evade or escape the effect of the judgment by bringing proceedings in other courts, according to the ruling of the Supreme Court of the United States in the cases last cited, and subject to the limitations therein contained, is, in its application, not confined to courts of the United States, but embraces also the courts of the several states. It is just as much the duty and the right and within the power of the State courts to secure litigants therein the full benefit of the judgment therein pronounced as it is in like circumstances the duty of the Federal court to extend protection to litigants within its jurisdiction.” [Gates v. Bucki, 53 Fed. l. c. 969.] And in this case it appears that immediately upon the filing of this injunction proceeding in the circuit court of St. Louis, the circuit court of the United States at once caused the circuit attorney to be cited before that court and the decree was so amended as to enjoin and prohibit him from further prosecuting this injunction ease in the circuit court of St. Louis. While it is insisted by the respondent that the cases are different, it is perfectly apparent to us that this injunction proceeding is an indirect appeal or method of reviewing and obstructing the decree of the Federal court. Thus in his brief, respondent says: “Inasmuch as the decree of the United States Court is based palpably on a misapprehension of the effect of the Session Act of 1907, page 170', repealing in terms section 1192, Revised Statutes 1899, it follows that relators cannot use the amended final decree as handed down by that court for the purpose of showing any rights which they profess to possess thereunder.” But the circuit court of the United States, having jurisdiction of that cause and having rendered a final decree *256therein and having under the equity practice obtaining in the Federal Courts retained jurisdiction for the purpose of enforcing its said decree and having brought the prosecuting attorney before it and made him a party to the said decree, it seems perfectly apparent to us that the. only orderly and regular way of avoiding the effect of this decree is by an appeal or writ of error from the judgment of the United States Circuit Court, and that decree cannot be impeached collaterally by the circuit court of the city of St. Louis without violating that principle of comity and jurisprudence that has ever obtained and marked the course of the State and Federal courts in this country, in matters where their jurisdiction might ordinarily be coordinate. It is intolerable under our system of laws that a law shall be interpreted and decided in two different ways under the same government. As was said by this court in Thomas v. Mead, 36 Mo. l. c. 249: “If this were to be allowed, or if there were no power in the Supreme Court to interfere by prohibition in the exercise of its original jurisdiction, and that superintending control which is given by the Constitution, the inferior courts might be brought into unseemly conflicts with one another, or with this court, and we might have to witness the disorderly and disgraceful spectacle of the officers of different courts, armed with contradictory process, meeting in direct collision in the public streets, and inaugurating riot and civil disturbance, while purporting to be acting in the name of one and the same executive authority.”
Under this writ of prohibition, it is not the province of this court to pass upon and review the judgment of the circuit court of the United States in the cases wherein the relators were the complainants and the Railroad and Warehouse Commissioners and the Attorney-General and other officers of this State were the defendants. It is enough for us at this time to know that that court had jurisdiction both of the par*257ties and the subject-matter and that in due course it rendered its decree and from that decree the defendants have the right to appeal to the Supreme Court of the United States, and this being so, that court having taken jurisdiction of this particular matter and having retained jurisdiction thereof, the circuit attorney of the city of St. Louis could not open up and have relitigated the questions involved in that record and determined in the decree of the Federal court by an injunction in the circuit court of the city of St. Louis; and in our opinion when the pendency of that proceeding and the decree of the circuit court of the United States was brought to the attention of the respondent, Judge Williams, then the restraining order should have been dissolved and no injunction granted to prevent the relators from exercising the rights which the decree in the Federal court secured to them, pending at least the appeal, if any shall be taken from that decree. Jealous as the States are, and of right ought to be, of the powers reserved to them in our dual form of government, it is still the duty of the officials of the State to recognize these powers, which have been granted to the Federal government by the States in the formation of our Constitution, and to uphold and respect them so long as the Federal authorities keep within the orbits prescribed for them by the organic law.
The Act of the General Assembly of Missouri of February 23rd, 1907, was assailed in the United States Circuit Court as unconstitutional. In Ex Parte Young, 209 U. S. l. c. 159, 164, the Supreme Court of the United States said: “The act to be enforced is alleged to be unconstitutional and if it be so, the use of the name of the State to enforce an unconstitutional act to the injury of complainant is a proceeding without the authority of and one which does not affect the State in its sovereign or governmental capacity. It *258is simply an illegal act upon the part of a State official in attempting by the use of the name of the State to enforce a legislative enactment which is void because unconstitutional. If the act which the State Attorney-General seeks to enforce be a violation of the Federal Constitution, the officer in proceeding under such enactment comes into conflict with the superior authority of that Constitution and he is in that case stripped of his official or representative character and is subjected in his person to the consequences of his individual conduct. . . . An act of the Legislature fixing rates, either for passengers or freight, is to be regarded as prima-facie valid and the onus rests upon the company to' prove its assertion to the contrary. Under such circumstances it was stated by Mr. Justice Miller, in his concurring opinion in Railroad v. Minnesota, 134 U. S. 418, 460, that the proper, if not the only, mode of judicial relief against the tariff of rates established by the Legislature or by its commission is by a bill in chancery asserting its unreasonable character, and that until the decree of the court in such equity suit was obtained it was not competent for each individual having dealings with a carrier or for a carrier in regard to each individual who demands its services, to raise a contest in courts over the questions which ought to be settled in this general and conclusive manner. This remedy by bill in equity is referred to and approved by the court in Railroad v. Gill, 156 U. S. 649, 659, 666, although that question was not then directly before the court. Such remedy is undoubtedly the most convenient, the most comprehensive and the most orderly way in which the rights of all parties can be properly, fairly and adequately passed upon. It cannot be to the real interest of any one to injure or cripple the resources of the railroad companies of the country, because the prosperity of both the railroads and the country is most intimately connected. The question of the sufficiency of rates is important and controlling and be*259ing of a judicial nature it ought to be settled at the earliest moment by some court and when a Federal court first obtains jurisdiction it ought on general principles of jurisprudence to be permitted to finish the inquiry and make a conclusive judgment to the exclusion of all other courts. This is all that is claimed and this we think must be admitted.”
The proceeding by the circuit attorney in this ease is of the same character as that pursued by the Attorney-General of Minnesota in that case. A Federal circuit court had in each case obtained jurisdiction and the Attorney-General in that ease assumed the right to proceed to enforce the enjoined State statute on the theory that the State was independent of the decrees of the Federal court, but he was cited for contempt and held to have been guilty of contempt in violating the injunction, and the Supreme Court of the United States affirmed the judgment of contempt. Reduced to its last practical analysis, this is the purpose of the circuit attorney in the injunction case in the circuit court of the city of St. Louis. It is a defiance of the decree of the United States Circuit Court, and if permitted to go on can be productive of no good, but may be of infinite harm, to say nothing of the annoyance of multiplied litigation. If the State of Missouri deems the decree of the United States Circuit Court erroneous and oppressive, it doubtless will appeal to the proper appellate court of the United States, and that court being the final arbiter where Federal questions are involved, every officer and good citizen must yield obedience. The United States Circuit Court having found the Act of the Missouri Legislature of February 23rd, 1907, unconstitutional and void and confiscatory, and that court having first obtained jurisdiction of that question, the orderly and proper way to settle that question finally is to appeal that case to the Federal appellate court and not by a multiplicity of other suits and prosecutions involving the same *260questions. In our opinion, this court, in the exercise of its superintending control over the circuit court of St. Louis, should prohibit the said court from further asserting jurisdiction of said injunction, at least, until after the appeal of the State from Judge McPherson's decree shall have been finally determined and reversed; for if affirmed, then there will be no further occasion for endeavoring to enforce the two-cent rate.
III. Whether the writ of prohibition should be awarded in this case also involves the important question, is the State a party to the injunction suit pending in respondent’s court “in its own behalf ¶
Section 3637, Revised Statutes 1899; provides:
“No injunction, unless on final hearing or judgment, shall issue in any case except in suits instituted by the State in its own behalf, until the plaintiff, or some responsible person for him, shall have executed a bond with sufficient surety or sureties to the other party, in such sum as the court or judge shall deem sufficient,” etc. The respondent, Judge Williams, not only granted the restraining and injunctive order without requiring a bond, but refused to set the same aside when moved to do so, on the ground that the State was a party to the injunction suit, and by the express language of the statute was relieved from giving the bond, and upon this position, issue is joined and the solution is full of difficulties, in view of the decisions of this court and of the Supreme Court of the United States. In State ex rel. Circuit Attorney v. Saline County Court, 51 Mo. 350, it was ruled after exhaustive discussion that the Attorney-General, and in a proper case the circuit attorney, could institute and prosecute proceedings in the name of the State to restrain public and private corporations from exercising powers not granted, and from abuse of those granted, and the decision was supported by many English decisions and is the accepted law of this State to-day, but while the *261Attorney-General may nse the name of the State in any county of the State, in a proper case, it hy no means follows that the circuit attorney of St. Louis or a prosecuting attorney or all prosecuting attorneys may use the name of the State in enjoining or restraining corporate delinquencies or abuses outside of their respective counties or city, or that they may use the name of the State to avoid giving bond, in any case.
The duties of the Attorney-General are defined hy statute and so are those of the prosecuting attorneys and a careful reading of sections 4943 and 4950, Revised Statutes 1899, will, we think, demonstrate that the law-making power charged the Attorney-General with the duty of conducting all litigation on behalf of the State, as distinguished from a county or some municipality, and that it was the obvious purpose to restrict the circuit attorney of St. Louis, and the various prosecuting attorneys of the counties of the State, to those matters which arise in their respective counties or city and which affect the interests of their respective local jurisdictions. It will not he seriously asserted, we think, hy any lawyer, that the circuit attorney of St. Louis has authority to prosecute a crime committed outside of the corporate limits of St. Louis, and yet the duties and powers of prosecuting attorneys are conferred hy the same section which limits such duties and powers to action in their respective counties. It appears that this was the view of the pleader who drew the hill in said injunction case because care is taken to allege that the relators are operating railroads and carrying on their business as common carriers not only in Missouri but in the city of St. Louis. However, it is perfectly obvious that the subject-matter of the action is not something that pertains solely to the city of St. Louis, hut is intended to enjoin railroads that do not approach the said city from any direction and are many miles distant therefrom.
Whatever may he the duties of the railroad com-*262parties under the laws of this State and whatever remedies may be enforced against them, it must he, so far as the city of St. Louis is concerned, with reference to the general subject-matter of the transportation of passengers throughout the State, and such unquestionably is the scope of this bill for injunction. So that to authorize the circuit attorney to sustain a hill of this character, affecting all the railroads of the State and their relation to the State at large, it must be conceded that his duties and powers are concurrent with those of the Attorney-General. . Clearly if the circuit attorney of St. Louis can maintain that suit, the Attorney-General could have done so, and the prosecuting attorneys of all the counties could have done so, and interminable confusion might result from their different theories and neither could control the other. If the theory of the respondent is carried to its logical conclusion, then the circuit attorney of St. Louis might institute such suit in any of the various counties. We do not think the decided cases warrant any such conclusion. In State ex rel. v. Saline County Court, 51 Mo. 350, the bonds which the county court was enjoined from issuing affected Saline county only, and the circuit attorney at that time was the representative of the State in the circuit in which Saline county was situated. That case affords no precedent for holding that the circuit attorney of St. Louis may institute such actions outside of St. Louis. As to State ex rel. v. Zachritz, 166 Mo. 307, that was a suit by the Attorney-General in the circuit court of St. Louis to annul and cancel certain licenses issued by the State Auditor to the Delmar Jockey Club, which it was alleged were obtained from the State Auditor “wrongfully, fraudulently and surreptitiously.” It is obvious that the decision rests upon the fact that the State had a direct pecuniary interest, in addition to its general governmental control. The other cases cited are based upon the violation of the express constitutional provision *263rendering unlawful the acts of public corporations. The circuit court held that the State was the plaintiff and for that reason refused to require a bond, and thus relators have no recourse against any one if their judgment in the United States Circuit Court is affirmed. If the State was the plaintiff in its own behalf the injunction suit should have been instituted by the Attorney-General, and not by the circuit attorney of St. Louis. In our opinion the use of the name of the State by the circuit attorney was entirely unauthorized and while advantage might be taken of this in the circuit court and cannot avail here to show want of jurisdiction, it does sufficiently appear that in legal and constitutional sense the State is not- such a party to this suit as to exempt the plaintiff from giving a bond as a condition precedent to the issuing of a temporary injunction. But it is evident, because it is so stated in the petition for injunction, that the circuit attorney and the circuit court rely for authority in the circuit attorney to institute the injunction proceeding and for the jurisdiction of the circuit court thereof, upon section 8970, Revised Statutes 1899, and the amendment thereof in 1907. [Laws of 1907, p. 379.] That section provides: “The several circuit courts of this State are hereby invested with jurisdiction to prevent and restrain any person or persons, corporation, partnership, individual or association of individuals, from entering into any combinations, pools, agreements in the form of trusts, confederation, conspiracy or understanding declared illegal by this act, or any other law of this State relative to pools, trusts, conspiracies and unlawful combinations.” By the very terms of this section and as amended, this special jurisdiction is vested to enjoin combinations, conspiracies, pools and trusts prohibited by that act, and that act does not relate to the transportation of passengers and it was so ruled in the Standard Oil case, 218 Mo. 1. In our opinion that act does not confer jurisdiction upon the *264circuit courts to restrain agreements as to passenger traffic, but is confined by its own terms to persons or corporations dealing in commodities. The question when the State is a party under the Eleventh Amendment to the Constitution of the United States exempting it from being sued by a citizen of another State and under the statute for removal of causes from the State courts to the Federal courts, has been so often ruled in the Supreme Court of the United States that we need only to refer to the last pronouncement on that subject in Ex Parte Young, 209 U. S. 123, and cases therein cited, to show that a suit like the injunction in the case of these relators v. The Attorney-General and Railroad and Warehouse Commissioners of the State is not a case against the State within the meaning of the Eleventh Amendment to the Constitution of the United States or the removal act. [Ex Parte Young, 209 U. S. l. c. 155; Reagan v. Loan & Trust Co., 154 U. S. 362.]
In our opinion there is no good reason why the circuit attorney should not have been required to file a bond as required by the statute, because in our opinion this was not and is not a suit instituted by the State in ité own behalf.
What then is the result of the failure of the court to require a bond before granting the restraining order or temporary injunction?
In his lucid and admirable style, Commissioner Martin, in City of St. Louis v. St. Louis Gaslight Co., 82 Mo. l. c. 353, pointed out the reason and origin of our statutory law requiring a bond as a condition precedent to obtaining an injunction. He said: “The matter in issue involves a question of equity practice and. jurisdiction as affected by our statutes relating to such questions. For a proper understanding of the issues it will be necessary to allude to the jurisdiction and practice of courts of equity in respect to damages consequent upon the dissolution of injunctions as it *265existed prior to and independent of statutes. "When temporary injunctions were granted, as they frequently were, upon the naked petition and ex parte showing of the applicant, and were afterwards dissolved in a final hearing of the cause, neither law nor equity furnished any remedy to the defendant for- the damages consequent from them, however serious they might be. Such damages were considered as flowing from the judgment and order of the court and not from the plaintiff, if he did nothing more than to sue in good faith for the process awarded him. The injustice which so often resulted from hasty and unfounded orders of injunction, for the consequences of which the courts alone were responsible under the law, induced them to adopt, as far as was in their power, such measures and safeguards as might afford the defendant an indemnity against loss and injury from injunctions which ought never to have been granted. ’ ’ Proceeding then to consider the meaning of section 3637 (then section 2710, R. S. 1879), the Commissioner said: “This provision, which has been in force since 1835, is very plain in its terms. [R. S. 1835, p. 314.] It assumes to control the discretion of the courts in respect to safeguards for the indemnity of the defendant and prescribes a particular one in the nature of a bond, which they must not fail to exact before issue of the order of injunction.”
Similar statutes to our section 3637, Revised Statutes 1899, are found in many other States and construed by their highest appellate courts. Thus in Nebraska it is provided that “no injunction, unless provided by special statute, shall operate until the bond required by said section has been filed and approved;” in State ex rel. v. Greene, 48 Neb. 327, the Supreme Court, among other things, said: “The order granted by Judge Sinclair, although purporting to be a temporary injunction, required no bond to be given by the relator, nor was one in fact thereafter *266executed. This order, therefore, never went into effect and had no validity whatever. .• . . Such is the meaning of sections 255 and 258.....It is no contempt to disregard a temporary injunction where no bond has been given to carry the order into effect.” •
In Kansas the statute is in all substantial respects like the section just quoted from Nebraska. In State ex rel. Bradford, Att’y-Gen’l. v. Lippert, 10 Pac. l. c. 539, Horton, C. J., said: “Said order of injunction, even if properly issued, is no obstacle to the granting of the elections because the statute provides that an injunction shall not operate until the party obtaining the same shall furnish an undertaking executed by one or more sufficient sureties. No proper undertaking was given prior to the commencement of the action.” It is significant this suit was brought by the Attorney-General in the name of the State.
In Ex Parte Miller, 129 Ala. 130, 87 Am. St. Rep. 49, it was ruled there can be no injunction in Alabama and consequently no contempt for its violation, until a bond has been given. “Such an order is conditional in its nature, and there can be no injunction until the bond is given. [2 High on Injunctions, sec. 1429; 1 Beach on Injunctions, sec. 269; Winslow v. Nayson, 113 Mass. 411.]”
In view of the reason of the statute exacting a bond as a condition precedent to the granting of an injunction, we are of the opinion that the requirement of it goes to the very jurisdiction of the court and that an injunction under the statute without requiring the bond and its execution and approval before the issuing of the injunction is and would be in excess of the jurisdiction of the circuit court; that, notwithstanding its general equity powers, the statute must control and be held to modify and regulate its jurisdiction, and when the consequences to a defendant are considered the statute is a wise and salutary one and should be *267enforced. On this point onr opinion is that the respondent in issuing his restraining order and refusing to discontinue, set aside or annul it, exceeded his jurisdiction and should be prohibited from further maintaining said temporary injunction and ordered to set aside the same.
