This is an appeal to review the action of the Eailroad Commission of Indiana in fixing a rate on coal, and also an order of the commission forbidding the way-billing of cars loaded with coal at their marked capacity when such cars would not hold the marked capacity when fully loaded.
This case arose out of proceedings taken by the commission under the act of the legislature approved Eebruary 28, 1905 (Acts 1905, p. 83, §5405a et seq. Burns 1905), entitled: “An act providing for the creation of a railroad commission, the appointment and compensation of the members thereof, prescribing the powers and duties of such commission- and its members, prescribing certain duties and obligations of railroad companies, express companies and other common carriers, defining certain misdemeanors and prescribing penalties, providing for the collection of penalties by civil action from railroad companies and other common carriers by the State in cases therein provided for, appropriating money to carry out its provisions, providing for a review of the decisions of the commission and conferring jurisdiction on certain courts to hear and determine such proceedings, and repealing all laws and parts of laws in conflict therewith.”
The first and second sections of the act create the commission, provide for the appointment of three commission*442ers, prescribe the qualifications, terms and salaries of the commissioners, the organization of the commission and where its sessions may be held.
The third section vests the commission with power and authority to supervise all railroad freight and passenger tariffs; to regulate car service -and the transfer of cars from one road to another, and to supervise charges therefor; to require and supervise the location and construction of sidings and connections between railroads, and the crossing of tracks and side-tracks of railroads by other railroads, vesting in the commission the authority now vested in the Auditor of State with reference to crossings and interlocking appliances; to supervise and regulate private car-line service and private tracks where the same are used in connection with any railroad in the State; to correct abuses and prevent unjust discrimination and extortion in freight and passenger tariffs on the different railroads, and to enforce the same by proceedings for the enforcement of penalties provided by law through courts of competent jurisdiction. The commission is also given power, upon failure of the railroads so to do, to fix and establish for all connecting lines reasonable joint rates of freight, transfer and switching charges; to fix the pro rata part of charges to be received by each of the two or more connecting roads, where such roads fail to agree; from time to time to alter, change, amend or abolish any classification or rate established by any company whenever found to be unjust or discriminative; to enforce reasonable and just rates for the use or transportation of loaded or empty cars and for storing and handling freight; to enforce reasonable rates for the transportation of passengers, and tolls or charges for all other service performed by any railroad company subject to the provisions of the act; to adopt and enforce such rules, regulations and modes of procedure as it may deem proper; to hear and determine complaints made against classifications or rates maintained by common carriers, or against *443the rules, regulations and determinations of the commission. This section also provides that its provisions shall be construed to mean that the commission shall have power to correct, alter, change or establish rates, charges, classifications, rules or regulations, where such companies fail to have just and reasonable and undiscriminative rates, charges, classifications, rules and regulations in effect, and shall exercise such power only where some person or corporation injuriously affected by such rate, charge, classification, rule or regulation, shall have filed with the commission a written verified complaint setting forth the unreasonable character of the rate, charge, classification, rule or regulation complained of, when the commission shall proceed to consider the reasonableness of the same and shall make such corrections, alterations, changes or new regulations, as may be necessary.
The fourth section provides for notice to the company, before rates or charges are revised or changed, for a hearing, that the commission may adopt rules to govern its proceedings, subpoena witnesses and order the production of books and papers, etc.
The fifth section reads: “In all actions between private parties and railroad companies or private car-line companies brought under this law, the rates, charges, orders, rules, regulations and classifications approved by or made by said commission before the institution of such action shall he held, deemed and accepted to be reasonable, fair and just, and in such respects shall not be controverted therein except as hereinafter provided until finally found otherwise in a direct action brought for that purpose in the manner prescribed by sections six, six and one-half and seven hereof.”
The sixth section provides that if any railroad company or party in interest be dissatisfied with any rate, classification, rule, charge or general regulation made, such company or party may procure a complete transcript of all the *444proceedings of the commission relative thereto, and also a copy of all the evidence heard, which evidence shall be incorporated into snch transcript, and such company or party may file such transcript, with a concise written statement of its or his causes of complaint against the action of the commission, in the office of the Clerk of the Appellate Court, who shall, after certain requirements as to notice are complied with, “place said cause upon the docket of the said Appellate Court for hearing and determination. The commission shall be_made a party_tp..such proceeding'UhT'the Appellate Court, and shall defend the same. All such causes shall be~given precedence over all other civil causes in said Appellate Court, and shall be heard and determined upon the transcript filed as aforesaid, as speedily as possible to the end that public interests may not suffer by reason of such appeal. Jurisdiction to hear and determine such appeals, and power to adopt rules of procedure to facilitate the speedy determination thereof not inconsistent with this act, are hereby conferred upon the Appellate Court of Indiana. The Appellate Court shall have power to affirm the action of the commission appealed from, or to change, modify or set aside the same as justice may requir&/Tne decision of the Appellate Court in any such matter shall be final, and said commission shall keep copies of all such findings and judgments on file in its office.”
The sixth section further provides that if the company or party in interest be dissatisfied with any order or regulation respecting the location or construction of sidings, switches or connections between railroads, or the crossing of one railroad by another, or the transfer or switching of cars at junction points, or the regulation of private tracks, such company or party may file a petition in the circuit or superior court of the particular county, setting forth the objections to the order, and after the requirements as to notice are complied with the case shall be set for hearing, “and shall be heard and determined as a suit in equity, *445without a jury.” The court may affirm the action of the commission, or change, modify or set the same aside. Either party may appeal from the finding and judgment to the Appellate Court in the same manner that appeals are prosecuted in civil cases from judgments of circuit and superior courts.
Section six and one-half provides: “All orders of the commission made and entered upon its records as herein provided respecting rates, charges, rules, regulations and classifications, or respecting the location or construction of sidings or connections between railroads, or to the crossing of one railroad by another, or the transfer and switching of cars at junction points, or the regulation of private tracks, shall be operative and in full force at and from the time fixed therefor by the commission as hereinafter provided, until any such order shall have been changed, modified or set aside by a circuit, superior or appellate court under the proceedings provided for in section six of this act: Provided, however, that if at the time of filing a transcript” in the Appellate Court, appealing from the fixing of any rate, the company filing such petition may, upon filing a bond specified, charge and collect the rate that existed before the making of the order by the commission, until such proceeding is finally determined; and if the company files the bond and continues to charge the old rate it shall give each person paying the old rate a certificate showing the amount received and the rate charged and containing a promise to refund the difference if the new rate is sustained by the Appellate Court. A penalty is provided for failure to comply, within a fixed time, with the promises contained in the certificate.
The seventh section provides that in all trials under section six “the burden of proof shall rest upon the plain-j tiff, who must show by clear and satisfactory evidence that; the rates, regulations, orders, classifications, acts or charges^ complained of are unreasonable and unjust to it or them.” *446Section eight requires the commission to furnish the company with a copy of rates, rules, etc., and provides that the company shall not increase its rates except after ten days’ notice to the commission. The first paragraph of section nine provides a penalty for failure to produce hooks, and the second makes it a misdemeanor for any officer or agent to fail to produce books. Section ten makes it a misdemeanor to fail to file a schedule of rates. Section eleven provides for interrogatories by the commission to the companies; makes a 'failure or refusal to answer, a misdemeanor; provides for annual reports to the Governor; for notice in certain cases to interstate commerce commission, and for certain limitations of the carrier’s liability. Section twelve provides that the commission, in making any examination or investigation provided for in the act, has power to issue subpoenas for the attendance of witnesses, each witness to receive per diem and mileage, and, if any witness fails or refuses to obey such subpoena, the commission may apply to a court to issue an attachment and compel him to attend; and if a witness after being duly summoned or ordered by any court shall fail or refuse to attend or to answer any question propounded to him, and which he would be required to answer if in court, such court may fine and imprison. A witness is not excused from testifying on the claim that the testimony may tend to incriminate him. The commission and all parties to any investigation shall in all cases have the right, in its or their discretion to issue proper process and take depositions, as in civil cases, instead of compelling personal attendance of witnesses. Section thirteen provides a penalty for violation of fixed rates. Section fourteen defines unjust discrimination, fixes a penalty and provides for reduced rates in certain cases. Section fifteen makes false billing and rebating misdemeanors. Section sixteen authorizes a civil action for damages suffered through the *447carrier’s violation of the act. Sections seventeen and eighteen provide certain penalties. Section nineteen provides for admission in evidence of certified copies of rates made by the commission. Section twenty makes it the duty of the commission to see that this act and all railroad laws are enforced, and to cause to be instituted proper proceedings to prosecute violations.
Section twenty-one: “The terms ‘road,’ ‘railroad,’ ‘railroad companies,’ ‘railroad corporations,’ ‘private car lines,’ ‘fast freight’ or ‘carrier,’ as used herein,- shall be taken to mean and embrace all corporations, companies, individuals and association of individuals, their lessees or receivers appointed by any court whatsoever, that may now or hereafter own, operate, manage or control any railroad or part of railroad in this State or any fast freight line or private car lines and express companies, and all such corporations, companies, and associations of individuals, their lessees or receivers that shall do the business of common carriers on any railroad in this State, (a) The provisions of this act shall be construed to apply to, and affect only the transportation of passengers, freight, express matter and cars between points within this State; and this act shall also apply to express companies: Provided, that this act shall not apply to street or interurban railroads, except as section three substitutes the railroad commission, created hereby for the Auditor of State, in respect to duties pertaining to the construction and maintenance of interlocking works at crossings of railroads and railroads operated by electricity.”
Section twenty-two provides that the act “shall not have the effect to release or waive any right of action by the State or any person for the right, penalty or failure which may have arisen, or may hereafter arise under any law of this State; and all penalties accruing under this act shall be cumulative of each other, and a suit for or recovery of one shall not be a bar to the recovery of any other penalty.”
*448Section twenty-three provides for certain reports and recommendations, by the commission, of road defects. Section twenty-fonr makes an appropriation to carry ont the act. Section twenty-five repeals all conflicting laws.
The railroad commission moves to dismiss the appeal, on the ground, among others, that this court has no jurisdiction to hear such pretended appeal; that the appeal is not taken from the final judgment or decree of any court or body exercising judicial authority; that sections six and six and one-half of the act of 1905, supra, are in conflict with article three of the Constitution of Indiana. Appellant answers this motion by admitting the claim of appellee, that this court has no jurisdiction, and that the two sections named are invalid, but insists that the act is wholly void because, among other reasons, by section twenty-one, the act deprives certain railways of equal protection of the law. Appellant suggests that as there is a constitutional question involved the jurisdiction is in the Supreme Court.
1. The motions to dismiss are for want of jurisdiction in this court to determine the appeal. It is quite true that this court has no jurisdiction of this appeal if the provision of the statute giving the right of appeal is invalid. And it is equally true that, although the provision giving the right to appeal be valid, this court has no jurisdiction of the merits of the appeal if the body making the order from which the appeal is taken had no jurisdiction to make the order. It is elementary that if the subordinate body is without jurisdiction the appellate body cannot gain it by an appeal. The appeal has been brought to this court as the statute directs. Its decision is made final. And while this court has not, in general appeals, any authority to pass on the constitutionality of a statute, yet under this statute it has been given exclusive appellate jurisdiction, and must necessarily pass upon such questions as go to the powers of the court to determine the appeal.
*4492. *448The case does not come to this court under the *449general enactments establishing the court and prescribing its jurisdiction, but is brought under a special statute, which designates this court as the tribunal to determine finally certain controversies arising between the railroad commission and the persons or corporations with whom it has to deal. The legislature certainly could not have intended that the jurisdiction of this court should be final and conclusive in this particular class of cases, and at the same time limited to a part only of questions arising upon appeal. We cannot consider any question presented by the appeal if there is no valid provision authorizing an appeal, nor can we consider any questions presented if the appeal is taken from an order itself invalid, because made under authority attempted to be conferred by an invalid statute. The first question a court must consider in the determination of a cause is that of jurisdiction. The case originated and has been brought to this court by virtue of an express statutory provision. If there is no authority in the statute for the steps that have been taken, no such authority exists. If the statute is void it is as if it had not been enacted, and any proceeding had under it by any court or by any tribunal is just as ineffective as would be the same proceeding without any attempted statutory authority.
Section six authorizes the appeal if the party is dissatisfied with any rate, classification, rule, charge or general regulation made, approved, adopted or ordered by the commission. Complaint is made in this appeal of a rate made by the commission, and also of what should perhaps be called a rule made as to way-billing cars. But the argument is directed to the making of the rate.
In the able briefs filed by a member of the commission on behalf of the commission, and by counsel for appellant company, and by the Attorney-General, a thorough discussion is had of the nature of the duty performed by the commission in the proceedings prescribed for fixing a rate.
*4503. Under the general railroad law the legislature granted to railroads authority “to regulate the time and manner in which passengers and property shall he transported, 'and the tolls and compensation to be paid therefor.” §5153 Burns 1901, §3903 R. S. 1881. Notwithstanding this grant of authority the legislature retains the right to regulate and to fix rates. Railroad Commission Cases (1886), 116 U. S. 307, 347, 6 Sup. Ct. 334, 29 L. Ed. 636.
4. The legislature might exercise this right by itself fixing the rates; or it might delegate this duty to a commission acting upon its own initiative; or it might leave with the railroads themselves the right to fix rates under the original grant of authority, subject to regulations and restrictions imposed,by a commission, and subject always to the requirement that the rate fixed must be reasonable. In enacting the statute under consideration the legislature followed the last-named method. The carrier had the right before the passage of the act to fix rates, and it has that right under the act.
5. It was required before the act to make rates reasonable; it is required to do the same thing novr. If, before the act, the carrier attempted to charge an unreasonable rate, the shipper could have redress through the courts. If the carrier attempts now to charge an unreasonable rate, a more prompt means of relief for such rate is given through a commission.
6. In determining whether a court may review the action of the commission in fixing a rate, the fact must be kept in view that the act gives the commission no power whatever to correct, alter, change or establish rates, except upon the filing of a written verified complaint setting forth the unreasonable character of the rate complained of; a hearing is given upon the complaint, after notice, and after such hearing the commission shall make such corrections, alterations, changes or new regulations as may be necessary to prevent injustice and discrimination *451to the party complaining; and when any such rate shall have been changed such order shall operate for the benefit of all persons or corporations situated similarly with the complaining party and on the line of the railroad complained of. The question which the commission tries is whether the rate fixed by the railroad and of which complaint is made is a just and reasonable rate. If it is not, the commission may, upon the evidence heard, fix a rate that is just and reasonable. If it is, the rate as fixed by the railroad stands. In the determination of this question of fact, witnesses may be subpoenaed and compelled to testify, testimony must be taken in shorthand, and all written and documentary evidence and all pleadings and other papers pertaining to the hearing shall be kept on file so that a complete transcript of all such proceedings, including the evidence, may be made whenever required. Or the commission and all parties.may take depositions instead of compelling personal attendance of witnesses, as depositions are taken in civil cases. The act also makes provision for the payment of witness fees, out of the state treasury, and for the payment of officers for executing process. In short, the act gives the commission all the authority necessary to make the investigation as to the facts complete. And all the evidence before the commission and upon which its decision is made is required by the act to be kept in the office of the commission.
In the above particulars the act differs materially from railroad commission acts in some other states, where the commission is given summary supervision of rates. See Chicago, etc., R. Co. v. Minnesota (1890), 134 U. S. 418, 33 L. Ed. 970, 10 Sup. Ct. 462.
So that, before the commission can grant any relief from the rate fixed by the railroad, it must first find that the rate of which complaint is made, and which was fixed by the railroad, is unjust or unreasonable. And in doing this in the manner prescribed by section three of the act, the *452commission pursues methods in many respects quite like that followed by the court, before the passage of the act, in giving relief from an unjust or unreasonable rate of which complaint was made. The first step necessarily taken in the one case is not materially different from the first step necessarily taken in the other. However, a. further duty is placed upon the commission, after it has found the rate complained of to be unreasonable, and that is to fix a rate that is reasonable, and the reasonableness of the rate fixed and the unreasonableness of the rate set aside are determined upon the same hearing.
7. Under points and authorities it is stated, in the original brief of appellee commission, that the most convincing reason that the commission is not a court is the fact that it is given authority to fix rates, which is purely a legislative duty. In the brief in reply to the State’s brief, the position taken by the commission is, that the power exercised by it in making rates is an administrative or executive power, and the argument in the same brief opens with the statement that “the Railroad Commission of Indiana, for whose members the writer speaks, is one of the coordinate branches of the State government.” The manner in which the statute requires the commission to proceed in disapproving a rate complained of, and fixing another to take its place, sufficiently shows that the power exercised is neither altogether legislative nor executive, and we know of no authority in the legislature to create a department of the state government in addition to those named in the Constitution. While the statute does not make the commission a court, and it is not a court, yet the act of setting aside the rate complained of — and this must be done before another rate can be fixed to take its place— and fixing another, upon evidence introduced, upon a complaint filed — in fact, a trial had with the aid of judicial process — may properly be said to be the exercise of a quasi-judicial duty. In any event, the power exerci'sed in ^this *453particular is more of a judicial than of an administrative/ character.
8. But whether the power exercised by the commission in ■fixing a rate is in its nature legislative, administrative or judicial is not decisive of the question presented./ It is conceded by counsel for appellee, in answer to appellant’s argument, that without section six the rate fixed by. the commission is conclusive and that, aside from any provision in this act, the courts are open to the carrier to prevent the enforcement of the order of the commission, if the rate established is unlawful. As the statute requires the rate to be just, reasonable and undiscriminative, if the commission fixes a rate that is not reasonable, its act is unlawful. A decision declaring the rate fixed to be unlawful, and whether unlawful because un-' reasonable, or unlawful because the statute was not followed in fixing it, is a judicial act, and is a question for the courts. It is not material by what delegated authority the rate is fixed, nor by what name the duty of fixing the rate is characterized, if the rate is unreasonable or unlawful the court will give protection against it. Reagan v. Farmers Loan, etc., Co. (1893), 154 U. S. 362, 367, 14 Sup. Ct. 1047, 38 L. Ed. 1014, 4 Interst. Com. Rep. 560; Chicago, etc., R. Co. v. Minnesota, supra; St. Louis, etc., R. Co. v. Gill (1895), 156 U. S. 649, 15 Sup. Ct. 484, 39 L. Ed. 567; Smyth v. Ames (1898), 169 U. S. 466, 42 L. Ed. 819, 18 Sup. Ct. 418; Burlington, etc., R. Co. v. Dey (1891), 82 Iowa 312, 48 N. W. 98, 31 Am. St. 477, 12 L. R. A. 436; Chicago, etc., R. Co. v. Jones (1894), 149 Ill. 361, 37 N. E. 247, 24 L. R. A. 141, 41 Am. St. 278; Atlantic Express Co. v. Wilmington, etc., R. Co. (1892), 111 N. C. 463, 16 S. E. 393, 32 Am. St. 805, 18 L. R. A. 393.
In Reagan v. Farmers Loan, etc., Co., supra, the court said: “It has always been recognized that, if a carrier attempted to charge y a shipper an unreasonable sum, the *454courts had jurisdiction to inquire into that matter and to award to the shipper any amount exacted from him in excess of a reasonable rate; and also in a reverse case to render judgment in favor of the carrier for the amount found to be a reasonable charge. The province of the courts is not changed, nor the limit of judicial inquiry altered, because the legislature instead of the carrier prescribes the rates. The courts are not authorized to revise or change the body of rates imposed by a legislature or a commission; they do not determine whether one rate is preferable to another, or what under all circumstances would be fair and reasonable as between the carriers and the shippers; they do not engage in any mere administrative work; but still there can be no doubt of their power and duty to inquire whether a body of rates prescribed by a legislature or a commission is unjust and unreasonable, and such as to work a practical destruction to rights of property, and if found so to be, to restrain its operation. * * * These cases all support the proposition that while it is not the province of the courts to enter upon the merely administrative duty of framing a tariff of rates for carriage, it is within the scope of judicial power and a part of judicial duty to restrain anything which, in the form of a regulation of rates, operates to deny to the owners of property invested in the business of transportation that equal protection which is the constitutional right of all owners of other property. There is nothing new or strange in this. It has always been a part of the judicial function to determine whether the act of one party (whether that party be a single • individual, an organized body, or the public as a whole), operates to divest the other party of any rights of person or property. In every constitution is the guarantee against the taking of private property for public purposes without just compensation.”
*4559. *454So that, when the unreasonableness or unlawfulness of the rate is thus brought before a trial court, it is tried and *455determined by the court as other questions of law and fact. And if, after a hearing, the court concludes that the rate is unreasonable, or that it has not been fixed according to law, or that it has not been fixed under a law authorizing its establishment, it may in effect set the act of the commission aside by restraining its enforcement. The determination of these questions is clearly the exercise of judicial authority. The question then presents itself: May the legislature require that a court shall determine these same questions, not by a trial, but by a review of all the proceedings and evidence taken by the commission? Whether it is, strictly speaking, an appeal within the generally accepted meaning of the term, is not' conclusive, but the question is, may the legislature require that the question be determined in that way ?
10. It is well settled that, under a «general statutory provision providing for an appeal from all decisions of the board of county commissioners, an appeal may be taken from any order of the board, if the duty of the board involves judicial action, unless the right of appeal is expressly or impliedly denied by the statute creating the duty. And it is also settled that an appeal will not lie under this general provision if the duty of the board does not involve judicial action, but consists in the performance of administrative, ministerial or discretionary powers. However, an appeal will lie from the action of the board where the only power exercised by the board is administrative, ministerial - or discretionary, if an appeal is expressly authorized by statute. See Bosley v. Ackelmire (1872), 39 Ind. 536; Moffitt v. State, ex rel. (1872), 40 Ind. 217; Baltimore, etc., R. Co. v. Board, etc. (1880), 73 Ind. 213; Grusenmeyer v. City of Logansport (1881), 76 Ind. 549; Padgett v. State (1884), 93 Ind. 396; City of Terre Haute v. Mack (1894), 139 Ind. 99; Board, etc., v. Davis (1894), 136 Ind. 503, 22 L. R. A. 515; Mode v. Beasley (1896), 143 Ind. 306. *456Thus appeals are authorized iu' highway eases, in drainage proceedings, street assessments, the action of purely administrative hoards, and in other matters where the action of the tribunal from which the appeal is authorized is in no sense judicial. It is quite true that these cases go to I trial court upon such appeal and are tried as original aci Uions. But these cases go to this point: That whether an appeal will lie from the action of an inferior tribunal or statutory board may or may not depend upon the capacity in which the tribunal or board acts in doing the thing re- ' quired of it, but it may depend entirely upon whether the \ legislature has said that there may be an appeal.
11. The legislature established the Appellate Court under the authority given by §1, article 7, of the Constitution, which provides that “the judicial power of the State shall be vested in a Supreme Court, in circuit courts, and in such other courts as the General Assembly may. establish.” It is manifest that the act in force February 28, 1891 (Acts 1891, p. 89), establishing the Appellate Court, invested the court with appellate jurisdiction only. By the first section of that act it was given jurisdiction of appeals from the circuit, superior and criminal courts in certain designated classes of eases. The clerk and sheriff of the Supreme Court are made the clerk and sheriff of the Appellate Court, and the judges of the Appellate Court were required to adopt the same uniform rules of practice as govern the Supreme Court. Appeals were required to be taken to the Appellate Court in the same manner as to the Supreme Court, and pleadings, practice and proceedings in the two courts were to be the same. The act did not create any new appellate jurisdiction, but simply took a part of the general appellate jurisdiction then existing and transferred it to the Appellate Court which the act created. The act did not undertake to confer upon the court any original jurisdiction and conferred none; and under that act the court had no original *457jurisdiction, except such as the court should necessarily exercise in aid of its appellate jurisdiction — an inherent power of all appellate tribunals. Prior to 1905 various amendments touching the court’s jurisdiction were made to the original act, and by the act in force March 12, 1901 (Acts 1901, p. 565, §9, §1337i Burns 1901), all appellate jurisdiction-was vested in the Appellate Court except in nine classes of cases, jurisdiction of which remained in the Supreme Court, But in none of these amendatory acts was any attempt made to confer any original jurisdiction, and none was conferred.
12. However, as this court is established by the legislature, the legislature has, within the constitutional limitations as to the judiciary, full power to define its procedure and jurisdiction. “It is true,” said the court in Hovey v. State, ex rel. (1891), 127 Ind. 588, 11 L. R. A. 763, 22 Am. St. 663, “that the legislative department may increase, or diminish, the jurisdiction of the [Supreme] Court, ánd may, within the terms of the Constitution, prescribe rules of practice.” It is equally true that the legislature may confer upon a court of its own creation either appellate or original jurisdiction, or both. Brown, Jurisdiction (2d ed.), §13. There is nothing in the Constitution that restricts its jurisdiction. The fact that it is called an “appellate court” and was created as a court of appeals, and that, strictly speaking, an appellate court can review a decision of a court only, does not preclude the legislature from' conferring upon it jurisdiction other than strictly appellate jurisdiction. The question is whether the particular duty placed upon the court is a judicial duty.
13. The sixth section of the act in question expressly provides that the secretary of the commission shall, upon request, furnish a complete transcript of all the proceedings of the commission relative to the action appealed from, also a copy of all the evidence which *458shall he incorporated into such transcript. This transcript is filed in the office of the clerk of this court, who dockets the same for hearing and determination. Jurisdiction is conferred to hear and determine the appeal, which is given precedence over other civil causes, and the cause “shall he heard and determined upon the transcript filed as aforesaid.” It is clear that the legislature did not intend that there should he a trial in this court, in the ordinary meaning of that term.
It is true that section three says that this court upon the appeal may “affirm, change, modify or set aside” the action of the commission. Whether the court would, upon final judgment, have power to change or modify a rate fixed hy the commission is not now presented. But it is manifest that the court might, as a court, determine whether the rate was legally established or whether it was established under a law authorizing it, and affirm or set aside the action of the commission in fixing the rate; and neither more nor less than this is done when the qu'estion of the unreasonableness of the rate is heard by a trial court. If the action of the commission should be affirmed, the rate is fixed, not by the court, but by the commission. The power to change or modify a rate is not at all essential to the power to affirm or set aside the order of the commission. It is quite true that it is an elementary principle that “upon judges as such no functions can be imposed except those of a judicial nature.” Cooley, Prin. of Const. Law, 53. And see Ex parte Griffiths (1888), 118 Ind. 83, 3 L. R. A. 398, 10 Am. St. 107; City of Terre Haute v. Evansville, etc., R. Co. (1897), 149 Ind. 174, 37 L. R. A. 189. But determining whether a rate has been legally established or whether the same is or is not reasonable, is a judicial function.
*45914. *458If, then, the duty to be performed is judicial, may the legislature prescribe the procedure ? It cannot be said that *459necessarily the only question that would be presented by this transcript would be the weight of the evidence. The power possessed by the commission is only such as the statute gives it. The method by which it is to proceed is pointed out. If this method is not pursued, its action is a nullity. The whole proceeding is a special, statutory one, and certain steps must be taken before the commission has any authority to proceed. Until the contrary appeared, the same presumption would prevail in favor of the action of the commission that prevails in a review of a judgment in a civil action. It is quite true, as argued, that it is not to be presumed that the commission would fix an unreasonable rate. But may it not also be said that it is not to be presumed that a court will render a wrong judgment ? Does not the same reason for a review exist in both cases ?
15. It is also argued that this provision in this act delegates to the commission — a non judicial body — the duty of hearing the evidence upon which a court is to render a decision. Even if it could be said that the only question that would necessarily be presented by the transcript would be on the weight of the evidence, and as stated, this would not necessarily be the only question, this objection to the manner of hearing the evidence would not be tenable. A case may be tried in the circuit court upon evidence consisting wholly of depositions taken by a notary public. A circuit court may refer a case to a master commissioner, to whom judicial power cannot be given (Shoultz v. McPheeters [1881], 79 Ind. 373), and make a finding from the evidence so taken, or pronounce a judgment upon a finding of facts made by the master from the evidence heard by him.
Our conclusion upon this branch of the case is that the legislature, in providing for an appeal to this court, has required of this court the performance of a judicial duty that may rightfully be imposed; that the legislature may *460vest the court with such jurisdiction as it sees fit, provided the duty required is a judicial duty; that in determining upon an appeal, whether the rate fixed by the commission has been established in due form of law, under a valid law and by a valid commission, and whether the rate fixed is a reasonable rate, the court is required to exercise judicial authority only. If the legality, or the reasonableness of a rate fixed by the commission may be questioned in a court, and it is so conceded and has been so decided, we think the legislature may designate the court in which, and the procedure by which, that review may be had. Eor the reasons given, the motion of appellee commission to dismiss the appeal is overruled.
16. Counsel, in support of appellant’s motion, have discussed at length the constitutionality of the act, claiming that it is unconstitutional, among other reasons, on the ground that it empowers the commission to fix a rate before the reasonableness of such rate has. been judicially determined, and on the ground that interurban roads are exempt from the provisions of the act. Appellant’s motion is not to dismiss the appeal, but to dismiss the petition. The petition or complaint is not filed in this court, but-comes to this court in the transcript of the proceedings of the commission. It is a part of the transcript filed in this court. If the act is invalid, as appellant insists, it is true that the commission has no authority to act, and from that it would necessarily follow that this court could have no jurisdiction of the appeal. Whether any motion in this court to dismiss a petition filed with the commission would be a proper motion to be considered by this court at any time we need not now determine. But, as to the motion now presented by appellant, the effect of a ruling in its favor upon the questions argued in support of its motion would be a determination of the appeal upon its merits. It is true, if the act is invalid, any act of the commission *461under its provisions would be without authority of law, and, in the consideration of the appeal on its merits, the constitutionality of the act would be the first question to be determined, but that question can not be raised by a motion to dismiss the petition.
The motion to dismiss the appeal is overruled.
