[194 U.S. 25, 26] This is an appeal from an order made in the circuit court of the United States for the southern district of New York in the matter of the petition of the Interstate Commerce Commission for orders requiring the testimony of witnesses and the production of certain books, papers, and documents. The petition recites that the Attorney General of the United States, at the request of the Interstate Commerce Commission, instructed the United States district attorney for the southern district of New York to present the petition and institute proper proceedings for the enforcement of the provisions of the acts to regulate interstate commerce, as amended, and to invoke the aid of the court in requiring the attendance and testimony of witnesses and the production of books, papers, and documents, pursuant to the provisions of said acts. The case [194 U.S. 25, 27] grows out of a complaint of William Randolph Hearst, filed on November 2, 1902, with the Interstate Commerce Commission, against the Philadelphia & Reading Railway Company, Lehigh Valley Railroad Company, Delaware, Lackawanna, & Western Railroad, central Railroad Company of New Jersey, New York, Susquehanna, & Western Railroad Company, Erie Railroad Company, New York, Ontario, & Western Railway Company, Delaware & Hudson Company, Pennsylvania Railroad Company, and Baltimore & Ohio Railroad Company.
In the complaint it was charged: That the defendants are common carriers, engaged in the transportation of passengers and freight between points in different states of the United States, and are particularly engaged in the transportation of anthracite and bituminous coal mined in Pennsylvania, Maryland, and West Virginia, and shipped as interstate traffic over said lines, and are carriers subject to the provision of the act of February 4, 1887 [24 Stat. at L. 379, chap. 104, U. S. Comp. Stat. 1901, p. 3154], to regulate commerce, and the acts amendatory thereto; that the rates charged and exacted by the defendants for the transportation of anthracite coal in carloads from points in the anthracite coal region of Pennsylvania to New York city and New York harbor points and internal points of destination in the state of New York, to Boston and other points in the New England states, to Baltimore and other points in the state of Maryland, and to Washington, in the District of Columbia, are unreasonable and unjust, and subject consumers and producers of such coal who are not common carriers or corporations owned and controlled by common carriers, to undue and unreasonable prejudice and disadvantage in favor of, and to the undue and unreasonable preference and advantage of, said defendants and companies under their control, in violation of 1 and 3 of the Act to Regulate Commerce; that the rates charged and exacted by the defendants for the transportation of anthracite coal are relatively unreasonable and unjust, and unjustly discriminating against the interests of dealers and consumers of that com- [194 U.S. 25, 28] modity as compared with the rates contemporaneously charged by said defendants for transportation of bituminous coal for much longer distances and to the points of destination above mentioned, and also as compare with the defendants' rates and charges on other carload freight generally, all of which is a violation of 1, 2, and 3 of the Act to Regulate Commerce; that the defendant companies-Lehigh Valley Railroad Company, Central Railroad Company of New Jersey, Delaware, Lackawanna, & Western Railroad Company, New York, Susquehanna, & Western Railroad Company, and the Philadelphia & Reading Railway Company-are, in the absence of agreement, natural competitors in the business of transporting anthracite coal from the coal fields of Pennsylvania to tidewater at New York, two of said defendants-the Lehigh Valley Railroad Company and the Central Railroad Company of New Jersey-being substantially parallel lines; that in 1896, 1897, 1898, 1899, 1900, and 1901 the six defendants last named, by an agreement and combination with one another, pooled, and have, during the year 1902, pooled, freights and freight traffic in anthracite coal, so as to divide the same between their different lines in agreed proportions, in violation of 5 of the Act to Regulate Commerce. The prayer of the petition was that the defendants be required to make answer to the charges, and, after hearing, for an order or orders commanding the said defendants, and each of them, wholly to cease and desist from each and every of the alleged violations of the Act to Regulate Commerce, and for such further order or orders and action by the Commission as its duty under the act and the cause of petitioner and others similarly situated may require. Answers were filed by the railroad companies, taking issue with the allegations of the petition and denying violation of the law. In the course of the hearing certain witnesses refused to produce contracts and answer questions when required so to do by order of the Commission, which refusal gave rise to the petition to the circuit court. The character of the testimony required by the order of the Commission is sufficiently [194 U.S. 25, 29] set forth in the opinion hereinafter given. To the petition answers were filed too legthy to abstract, and in substance setting forth the right of the defendants to refuse the production of the papers and documents and to decline to answer the questions because the same did not relate to any subject which the Commission had the right to investigate, and the contracts relate to the private business of persons not parties to the proceedings before the Commission; that the witnesses are protected in their right to refuse to produce the contracts or answer the questions by the 4th, 5th, and 10th Amendments to the Constitution of the United States; that the contracts were not relevant to the subject-matter of investigation before the Commission. The circuit court placed its decision on the latter ground, and dismissed the petition of the Interstate Commerce Commission.
Mr. Justice Day, after making the foregoing statement, delivered the opinion of the court:
Messrs. William A. Day and John G. Carlisle for appellant.
[194 U.S. 25, 31] Messrs. John G. Johnson, Walter W. Ross, Adelbert Moot, George F. Brownell, Francis I. Gowen, F. H. Janvier, J. D. Campbell, Robert Thorne, and Robert W. Deforest for appellees.
Statement by Mr. Justice Day:
A motion is made to dismiss the appeal upon the ground that no direct appeal lies to this court from the order of the circuit court. The act of February 19, 1903 [32 Stat. at L. 849, chap. 708; U. S. Comp. Stat. [194 U.S. 25, 36] 1901, Sup. of 1903, p. 365], to further regulate commerce with foreign nations and among the states, 3, closing paragraph, enacts, 'Provided. That the provisions of an act entitled [32 Stat. at L. 823, chap. 544]1 'An Act to Expedite the Hearing and Determination of Suits in Equity Pending or Hereafter Brought Under the Act of July Second, Eighteen Hundred and Ninety, Entitled 'An Act to Protect Trade and Commerce Against Unlawful Restraints and Monopolies,' [26 Stat. at L. 209, chap. 647, U. S. Comp. Stat. 1901, p. 3200] 'An Act to Regulate Commerce,' Approved February Fourth, Eighteen Hundred and Eighty-seven, [24 Stat. at L. 379, chap. 104, U. S. Comp. Stat. 1901, p. 3154] or Any Other Acts having a Like Purpose That May Be Hereafter Enacted, Approved February Eleventh, Nineteen Hundred and Three, shall apply to any case prosecuted under the direction of the Attorney General in the name of the Interstate Commerce Commission.'
The 2d section of the act of February 11, 1903 (U. S. Comp. Stat. 1901, Sup. for 1903, p. 376), provides, 'That in every suit in equity pending or hereafter brought in any circuit court of the United States under any of said acts [having reference to the anti-trust act of 1890 and the Act to Regulate Commerce mentioned in the preceding section] wherein the United States is complainant, including cases submitted but not yet decided, an appeal from the final decree of the circuit court will lie only to the Supreme Court, and must be taken within sixty days from the entry thereof.'
In support of the motion to dismiss it is argued that the language of the proviso of 3, above quoted, 'shall apply to any case prosecuted under the direction of the Attorney General in the name of the Interstate Commerce Commission,' must be read in connection with preceding paragraphs of the section, which provide for bringing actions by direction of the Attorney General in the circuit courts of the United States, and do not include proceedings of the character of the present action to compel the production of books and papers and the giving of testimony by witnesses called before the Commission.
It is true that the office of a proviso, strictly considered, is to make exception from the enacting clause, to restrain generality and to prevent misinterpretation. Minis v. United [194 U.S. 25, 37] States, 15 Pet. 423; 10 L. ed. 791; Austin v. United States, 155 U.S. 417 - 431; 39 L. ed. 206-211, 15 Sup. Ct. Rep. 167; White v. United States, 191 U.S. 545 , 551, ante, p. 171, 24 Sup. Ct. Rep. 171. It is apparent that this proviso was not inserted in any restrictive sense or to make clear that which might be doubtful from the general language used. It was inserted for the purpose of enlarging the operation of the statute so as to include a class of cases not otherwise within the operation of the section. It may be admitted that this use of a proviso is not in accord with the technical meaning of the term or the office of such part of a statute when properly used. But it is, nevertheless, a frequent use of the proviso in Federal legislation to introduce, as in the present case, new matter extending rather than limiting or explaining that which has gone before.
In Chesapeake & P. Teleph. Co. v. Manning, 186 U.S. 238, 242 , 46 S. L. ed. 1144, 1146, 22 Sup. Ct. Rep. 881, 883, the subject was under consideration, and Mr. Justice Brewer, delivering the opinion, while recognizing the restrictive office of a proviso as stated by Mr. Justice Story in Minis v. United States, 15 Pet. 423, 445, 10 L. ed. 791, 799, added: 'While this is the general effect of a proviso, yet in practice it is not always so limited. As said in Georgia R. & Bkg. Co. v. Smith, 128 U.S. 174, 181 , 32 S. L. ed. 377, 380, 9 Sup. Ct. Rep. 47. The general purpose of a proviso, as is well known, is to except the clause covered by it from the general provisions of a statute, or from some provisions of it, or to qualify the operation of the statute in some particular. But it is often used in other senses. It is a common practice in legislative proceedings, on the consideration of bills, for parties desirous of securing amendments to them to precede their proposed amendments with the term 'provided,' so as to declare that, nothwithstanding existing provisions, the one thus expressed is to prevail, thus having no greater signification than would be attached to the conjunction 'but' or 'and' in the same place, and simply serving to separate or distinguish the different paragraphs or sentences.'
The provision in the statute under consideration being intended to enlarge rather than limit the application of previous terms should not receive so narrow a construction as to defeat [194 U.S. 25, 38] its purpose. It extends the terms of the act of February 11, 1903, to 'any case' brought under the direction of the Attorney General in the name of the Interstate Commerce Commission. The 2d section of the act of February 11 has reference, it is true, to a suit in equity under certain acts wherein the United States is complainant, and the argument is that the extension of the terms of this act in the act of February 19 is only to suits in equity. But for some reason Congress, in the act under consideration, saw fit not to limit the terms of the extension to suits or proceedings provided for in 3 of the act of February 19, or to suits in equity, but broadly extended the rights and privileges of the act of February 11 to 'cases' of the character designated. We cannot assume that this use of the broader term was without purpose. Before the passage of this act this court had held that a petition filed under 12 of the Interstate Commerce Act2 against a witness duly summoned to testify before the Commission, to compel him to testify or to produce books, documents, and papers relating to the matter in controversy, makes a case or controversy to which the judicial power of the United States extends. Interstate Commerce Commission v. Brimson, 154 U.S. 447 , 38 L. ed. 1047, 4 Inters. Com. Rep. 545, 14 Sup. Ct. Rep. 1125. The object of construction, as has been often said by the courts and writers of authority, is to ascertain the legislative intent, and, if possible, to effectuate the purposes of the lawmakers. We cannot read these statutes without perceiving the manifest purpose of Congress to facilitate the disposition of cases brought under the direction of the Attorney General to enforce the provision of the anti-trust and interstate commerce statutes. The present proceeding is not merely advisory to the Commission, but, as was said in Interstate Commerce Commission v. Brimson, 154 U.S. 447 , 38 L. ed. 1047, 4 Inters. Com. Rep. 545, 14 Sup. Ct. Rep. 1125, a judgment rendered will be a final and indisputable basis of action as between the Commission and the defendant, and furnish a precedent for similar cases. While it has for its object the obtaining of testimony in aid of proceedings before the Commission, it is evident that important questions may be in- [194 U.S. 25, 39] volved touching the power of the Commission and the constitutional rights and privileges of citizens. Congress deemed it imperative that such cases, affecting the commerce of the country as well as personal rights, should be promptly determined in a court of last resort.
If the appeal in the first instance was to the court of appeals the judgment of that court would not be final under the act of March 3, 1891 [ 26 Stat. at L. 826, chap. 517, U. S. Comp. Stat. 1901, p. 547], and in such case this court would still be required to consider the cases on final appeal. We think it was the purpose of the act to eliminate an appeal to the circuit court of appeals, and to permit the litigation to be shortened by a direct appeal to this court.
We pass, now, to the merits of the controversy. The record in this case is voluminous, and much of the discussion before the Commission is printed. We shall endeavor to classify and consider the questions made so as to indicate our holdings with a view to a proper judgment in the ease.
It is urged that the complainant before the Commission did not show any real interest in the case brought and that the proceeding should, for that reason, have been dismissed. It is provided in the Act to Regulate Commerce, 13, that 'any person, firm, corporation,' etc., complaining of anything done or omitted to be done by any common carrier subject to the provisions of this act, in contravention of the provisions thereof, may apply to said Commission by petition, etc. And certain procedure is provided for-and (said Commission) 'may institute any inquiry on its own motion in the same manner and to the same effect as though complaint had been made,' and the section concludes: 'No complaint shall at any time be dismissed because of the absence of direct damage to the complainant.' In face of this mandatory requirement that the complaint shall not be dismissed because of the want of direct damage to the complainant, no alternative is left the Commission but to investigate the complaint, if it presents matter within the purview of the act and the powers granted to the Commission. [194 U.S. 25, 40] Power is conferred upon the Commission, under 12 of the act as amended March 2, 1889 (25 Stat. at L. 858, chap. 382, U. S. Comp. Stat. 1901, p. 3162), and February 10, 1891 (26 Stat. at L. 743, chap. 128, U. S. Comp. Stat. 1901, p. 3162), to inquire into the management of the business of all common carriers subject to the provisions of the act, and to keep itself informed as to the manner and method in which the same is conducted, with the right to obtain from such common carriers full and complete information necessary to enable the Commission to perform the duties and carry out the objects for which it was created.
In making the orders which were the basis of the application to the circuit court, and in the petition filed therein, it is set forth that the Commission, at the time when the witnesses refused to produce the contracts required was engaged 'in the discharge of its duty to execute and enforce the provisions of the Act to Regulate Commerce, and in the exercise of its authority to inquire into the business of common carriers subject to the provisions of the act, and to keep itself informed as to the manner and method in which said business is conducted, and to obtain from said common carriers full and complete information necessary to enable it to perform the duties and carry out the objects for which it was created; and your petitioner is of the opinion that said contracts are not only material and relevant to the issues on trial in said proceeding, but that the production thereof as required by it, as aforesaid, is necessary to enable your petitioner to discharge its duty and execute and enforce said provisions of said Act to Regulate Commerce and to inform your petitioner as to the manner and method in which the business of said common carriers is conducted, and to enable your petitioner to obtain the full and complete information necessary to enable your petitioner to perform the duties and carry out the objects for which it was created.'
But in the present case, whatever may be the right of the Commission to carry on an investigation under the general powers conferred in 12, this proceeding was under the [194 U.S. 25, 41] complaint filed, and we will examine the testimony offered with a view to its competency under the allegations made by the complainant.
Coming now to the specific items of testimony which the circuit court, in dismissing the petition, considered irrelevant to the controversy, we will first consider the socalled coal purchase contracts.
It is unnecessary for the present purpose to go into detail as to the provisions of these contracts. In the main they were made with coal companies owned principally by the railroad companies and contain the same general provisions. Among others, the purchase price of anthracite coal above a certain size is to be 65 per cent of the average price, computed monthly, at certain tide points, of coal of the same quality and size. All the coal mined by the contracting operators is sold, shipments to be made as called for by the purchasers.
While the contracts were produced for inspection, the witnesses refused to permit them to be given in evidence. The circuit court held them to be irrelevant upon the ground that they related solely to an intrastate transaction,-the sale of the coal in Pennsylvania,-and had nothing to do with interstate commerce. It appears that the railroad companies proceeded against in the complaint are engaged in carrying coal from the anthracite coal regions to tidewater. The contracts are between certain coal companies and independent operators engaged in mining coal in that region. The testimony shows that the coal companies making the contracts are principally owned by the railroad companies. For what purpose this separate ownership is maintained it is not necessary now to inquire. The fact of such ownership is undisputed, and for the present purpose it may be conceded that the ownership is lawful under the laws of the state of Pennsylvania.
The railroads are all engaged in interstate commerce, and into their affairs and methods of doing business the Commission might be, and is, lawfully authorized by the commerce act to make investigation. In speaking of this power as under- [194 U.S. 25, 42] taken to be vested in the Commission, this court said in the Brimson Case, 154 U.S. 472 , 38 L. ed. 1055, 4 Inters. Com. Rep. 554, 14 Sup. Ct. Rep. 1131: 'It was not disputed at the bar, nor indeed can it be successfully denied, that the prohibition of unjust charges, discriminations, or preferences by carriers engaged in interstate commerce, in respect to property or persons transported from one state to another, is a proper regulation of interstate commerce, or that the object that Congress has in view by the act in question may be legitimately accomplished by it under the power to regulate commerce among the several states. In every substantial sense such prohibition is a rule by which interstate commerce must be governed, and is plainly adapted to the object to be accomplished. The same observation may be made in respect to those provisions empowering the Commission to inquire into the management of the business of carriers subject to the provisions of the act, and to investigate the whole subject of interstate commerce as conducted by such carriers, and in that way to obtain full and accurate information of all matters involved in the enforcement of the act of Congress. It was clearly competent for Congress, to that end, to invest the Commission with authority to require the attendance and testimony of witnesses, and the production of books, papers, tariffs, contracts, agreements, and documents relating to any matter legally committed to that body for investigation.'
In Interstate Commerce Commission v. Cincinnati, N. O. & T. P. R. Co. 167 U.S. 479, 506 , 42 S. L. ed. 243, 255, 17 Sup. Ct. Rep. 896, 903, this court held that the Commission had no power to fix rates. In the course of the opinion it was said: 'It [the Commission] is charged with the general duty of inquiring as to the management of the business of railroad companies, and to keep itself informed as to the manner in which the same is conducted, and has the right to compel complete and full information as to the manner in which such carriers are transacting their business.'
The testimony shows that much of the coal purchased under these contracts is sold in Pennsylvania, but a considerable portion is carried to tide water. The coal is purchased by [194 U.S. 25, 43] companies owned by the railroads, for which payment is made on the basis of 65 per cent of the general average price received at tidewater by the sale of sizes above pea coal, leaving 35 per cent for the purchaser, from which he must pay transportation charges and cost of sale. Here is a railroad company engaged at once in the purchase of coal through a company which it practically owns and the transportation of the same coal through different states to the seaboard. Why may not the Interstate Commerce Commission, under the powers conferred, and under this complaint, inquire into the manner in which this business is done? It has the right to know how interstate traffic is conducted, the relations between the carrier and its shippers, and the rates charged and collected. We see no reason why contracts of this character, which have direct relation to a large amount of its carrying trade, can be withheld from examination as evidence by the Commission. These contracts were made by the officials of the railroad companies, who were also officials of the coal companies, after protracted conferences. Upon the ground that they pertained to the manner of conducting a material part of the business of these interstate carriers, which was under investigation, we think the Commission had a right to demand their production. And, further, it was claimed that, while these contracts were in form purchases of coal, their real purpose was to fix a rate for transportation to the carriers, who were in fact paid for the only interest they had in the coal,-the right to receive pay for its transportation,-by the percentage retained from the selling price after deducting charges and expenses in marketing the coal.
It is to be remembered in this connection that we are not dealing with the ultimate fact of controversy, or deciding which of the contending claims will be finally established. This is a question of relevancy of proof before a body not authorized to make a final judgment, but to investigate and make orders which may or may not be finally embodied in judgments or decrees of the court. If the railroad companies in fact re- [194 U.S. 25, 44] ceived their compensation for carriage from the sum retained by the coal companies as was claimed, then, whether they realized more or less than their published rates depended upon the price of coal. Taking the prices at times as shown in the statements filed with the Commission, it is apparent that the 35 per cent was less than published rates, and if that was the sum received for transportation, would work a discrimination against coal companies not having such contracts, and paying the full rate. On the other hand, if the coal companies paid the full rate, and failed to realize as much from the percentage of the selling price retained, they would be losing money, and as they were owned by the railroad companies the loss would be ultimately theirs, and not the coal companies. It may be that the Commission or the courts will ultimately find that these contracts do not fix the compensation received by the carriers, and that, as claimed, the full rate is paid by these purchasing companies, and if there is a loss on these contracts it is made up in other business; but, as we have said, the question concerns the relevancy of proof, and not whether it finally establishes the issue made, one way or the other. Relevancy does not depend upon the conclusiveness of the testimony offered, but upon its legitimate tendency to establish a controverted fact. Relevancy is that 'quality of evidence which renders it properly applicable in determining the truth or falsity of the matter in issue between the parties to a suit.' 1 Bouvier Law Dict. Rawle's Revision, 866.
The inquiry of a board of the character of the Interstate Commerce Commission should not be too narrowly constrained by technical rules as to the admissibility of proof. Its function is largely one of investigation, and it should not be hampered in making inquiry pertaining to interstate commerce by those narrow rules which prevail in trials at common law, where a strict correspondence is required between allegation and proof.
It is contended in the answers filed in the circuit court that to require the production of these contracts would be to compel [194 U.S. 25, 45] the witnesses to furnish evidence against themselves which might result in forfeiture of estate, in violation of the 5th Amendment to the Constitution; would subject the parties to unreasonable searches and seizure of their papers, contrary to the 4th Amendment, and would require them to produce papers pertaining wholly to intrastate affairs, in violation of the reserved rights of the people of the states, and beyond the power of the Commission, whose duties are limited to investigations pertaining to interstate commerce.
At the hearing the constitutional objections do not seem to have been relied upon; those argued pertained to the relevancy of the proof and the rights of persons not before the court to be protected from the publication of their private contracts. As to the constitutional objection based upon the 5th Amendment, the act as amended February 11, 1893 [27 Stat. at L. 443, chap. 83, U. S. Comp. Stat. 1901, p. 3173], expressly extends immunity from prosecution or forfeiture of estate because of testimony given in pursuance of the requirements of the law. The full consideration of the subject and the decision of this court in Brown v. Walker, 161 U.S. 591 , 40 L. ed. 819, 5 Inters. Com. Rep. 369, 16 Sup. Ct. Rep. 644, renders further consideration of this objection unnecessary.
The origin and interpretation of the 4th Amendment to the Constitution, securing immunity from unreasonable searches and seizures, was fully discussed by Mr. Justice Bradley in the leading case of Boyd v. United States, 116 U.S. 616 , 26 L. ed. 746, 6 Sup. Ct. Rep. 524. In that opinion the learned Justice points out the analogy between the 4th and 5th Amendments, and the object of both to protect a citizen from compulsory testimony against himself which may result in his punishment or the forfeiture of his estate, or the seizure of his papers by force, or their compulsory production by process for the like purpose. In the course of the opinion it is said: 'Breaking into a house and opening boxes and drawers are circumstances of aggravation; but any forcible and compulsory extortion of a man's own testimony or of his private papers to be used as evidence to convict him of crime or to forfeit his goods is within the condemnation of that judgment. In this regard the 4th and [194 U.S. 25, 46] 5th Amendments run almost into each other.' And see Adams v. New York ( decided at this term), 193 U. S. ante, p. 372, 24 Sup. Ct. Rep. 372.
As we have seen, the statute protects the witness from such use of the testimony given as will result in his punishment for crime or the forfeiture of his estate. Testimony given under such circumstances presents scarcely a suggestion of an unreasonable search or seizure. Indeed, the parties seem to have made little objection to the inspection of the papers, the contest was over their relevancy as testimony. Nor can we see force in the suggestion that these contracts were made with persons not parties to the proceeding. Undoubtedly the courts should protect nonlitigants from unnecessary exposure of their business affairs and papers. But it certainly can be no valid objection to the admission of testimony, otherwise relevant and competent, that a third person is interested in it.
As to the so-called Temple Iron Company contracts: It appears that in 1889 certain operators in the anthracite coal region organized a competing railroad, with a view to carrying their product from the coal regions to market at tidewater. It became evident that this company was likely to succeed, and to construct a competing railroad from the coal fields to the sea. With a view to acquiring its property, five of the leading railroad carriers purchased the collieries whose proprietors were developing the new scheme. To pay for these the charter of the Temple Iron Company was purchased and its capital stock increased. The company issued a large amount of stock and bonds, and the contracting railroad companies agreed among themselves and with the Guaranty Trustee Company of New York, as trustee, to guarantee a 6 per cent dividend upon the Temple Iron Company stock and the payment of principal and interest of the bonds. This ended the building of an independent line, and the transportation of coal from the collieries is distributed among the carriers interested.
It is argued that these contracts, if given in evidence, will tend to show a pooling of freights, in violation of the 5th [194 U.S. 25, 47] section of the commerce act. While this testimony may not establish such an arrangement as is suggested, it has, in our opinion, a legitimate bearing upon the question. There is a division of freight among several railroads, where, by agreement or otherwise, the companies have a common interest in the source from which it is obtained. Furthermore, we think the testimony competent as bearing upon the manner in which transportation rates are fixed, in view of determining the question of reasonableness of rates, into which the Commission has a right to inquire. To unreasonably hamper the Commission by narrowing its field of inquiry beyond the requirements of the due protection of rights of citizens will be to seriously impair its usefulness and prevent a realization of the salutary purposes for which it was established by Congress.
An appeal is also prosecuted from the refusal of the circuit court to order the witnesses Eben B. Thomas and William H. Truesdale to answer certain questions respecting the prices and sale of coal. Upon the principles already discussed we think these questions had legitimate bearing upon the matters into which the Commission was making inquiry.
We are of the opinion that the circuit court erred in holding the contracts for the purchase of coal by the companies or directly by the railroad, where a percentage of the price was agreed to be paid for the coal, to be irrelevant, and in refusing to order their production as evidence by the witnesses who are parties to the appeal, and likewise erred as to the Temple Iron Company contracts, and in refusing to require the witnesses aforesaid to answer the questions stated in the petition, and the order appealed from is reversed, and the cause is remanded to the Circuit Court for further proceedings in accordance with this opinion.
Mr. Justice Brewer dissents.
