Texas Railway Company v. United States (289 U.S. 627)/Opinion of the Court
The Galveston Commercial Association complained to the Interstate Commerce Commission that carload commodity rates on import, export, and coastwise traffic between a portion of western classification territory and Galveston were unreasonable, and their relationship with those to and from Houston, Texas City, Beaumont, Port Arthur, and Orange, Texas, and New Orleans, La., was unduly prejudicial to Galveston.  The claim of unreason ableness was abandoned, as was also the assertion of discrimination in favor of the other Texas ports. The latter intervened and prayed the same relief as might be accorded Galveston in respect of rate relationship with New Orleans. The issue was therefore narrowed to one of prejudice to them and preference of New Orleans. Railroads serving the Texas ports and various shippers and commercial bodies intervened in support of the complaint; interests connected with the port of New Orleans and shippers intervened in opposition.

The Commission found that export and import rates on fourteen commodities from or to points in Arkansas, Texas, Oklahoma, Southern Kansas, and Louisiana west of the Mississippi river were unduly prejudicial to Galveston and unduly preferential of New Orleans. In all instances where the distance to Galveston is less than the distance to New Orleans by not over one hundred miles it permitted equal rates; but for differences in distance exceeding one hundred miles it prescribed certain named minimum differentials in favor of Galveston. 

On rehearing the prior decision was modified b  including the other Texas ports with Galveston in the finding of undue prejudice; substituting a 25 per cent. difference in distance for the 100-mile basis; exempting from the scope of the order rates to or from points on the Texas & Pacific and the Louisiana Railroad & Navigation Company;  exempting rates on petroleum and its products; and making certain other changes not here material. 

The proceeding was later reopened for the purpose of deciding whether the Texas & Pacific and the L.R. & N. should continue to be exempted. The Commission reversed its previous finding and included them within its orders.  Both carriers filed bills in the District Court to enjoin the enforcement of all the orders except in so far as the second exempted them from the finding of preference and prejudice. The cases were consolidated, and upon final hearing before three judges the bills were dismissed.  The plaintiffs, Texas & Pacific and L.R. & N., and also the state of Louisiana, the New Orleans traffic bureau, and other interveners appealed.

The Texas ports are served by some half dozen lines which either themselves or through their connections reach the areas of origin or destination embraced in the Commission's order. Generally speaking, their routes trend north rather than east of Galveston. The Southern Pacific is the only carrier serving both Galveston and New Orleans. Texas is also connected with New Orleans by the Gulf Coast Lines, by the Texas & Pacific, extending east from El Paso through Dallas and Fort Worth to Shreveport, La., and thence southeast to New Orleans, and by the L.R. & N., which connects Eastern Texas and Western Louisiana with that port. Several other lines extend between New Orleans and Western Louisiana, Arkansas, Kansas, and Oklahoma.

With minor and immaterial exceptions, the carriers serving the Texas ports and New Orleans have for many years equalized the import and export commodity carload rates between the territory embraced in the Commission's orders and Galveston and New Orleans. The gravamen of the complaint is that in many instances the distance to New Orleans is so much greater than that to the Texas ports, and the increased haul so important a part of the service rendered, that this factor should be reflected in a fixed differential in rates. The Commission's order prescribing differentials is challenged only in so far as it compels the Texas & Pacific and the L.R. & N. to establish rates to New Orleans higher by the amount of the fixed differentials than those charged between the same interior points and the Texas ports. Inasmuch as the assertion of unreasonableness was withdrawn and the Commission made no finding that the Galveston rates were unreasonable, the prohibitions of section 1 of the act to regulate commerce, as amended, are not involved.  The evidence failed to show that the rates of the Texas & Pacific and the L.R. & N. on export and import shipments to and from New Orleans were not compensatory. The Commission refused to find that they were so low as to cast a burden on other traffic. There was therefore no basis for an order fixing minimum reasonable rates under section 15(1) of the Act.  The parties agree that authority for the order must be found in section 3(1), which is:

'It shall be unlawful for any common carr er * * * to make or give any undue or unreasonable preference or advantage to any particular person, company, firm, corporation, or locality, or any particular description of traffic, in any respect whatsoever, or to subject any particular person, company, firm, corporation, or locality, or any particular description of traffic, to any undue or unreasonable prejudice or disadvantage in any respect whatsoever.' 

The appellants contend that in the circumstances disclosed the ports as such are not localities preferred or prejudiced, but that, if they may be so denominated, the Texas & Pacific and the L.R. & N. cannot be held responsible for any undue prejudice to the Texas ports, since they do not reach those ports with their own lines or control the rates to or from them. They also assert that the orders violate article 1, § 9, of the Constiution, which prohibits any regulation of commerce giving preference to ports of one state over those of another; are without support in the evidence, and arbitrary.

The cause has been twice argued; it was first presented at the October term, 1931, and on account of the importance of the questions involved a reargument was ordered and was had at the October term, 1932.  Statement of certain facts and settled principles will tend to clarify and define the issues presented.

The traffic with which we are concerned does not move on through bills of lading, but the movement is, nevertheless, from points of origin to a foreign or coastal destination, or vice versa, and is therefore essentially through transportation. Compare Binderup v. Pathe Exchange, 263 U.S. 291, 309, 44 S.Ct. 96, 68 L.Ed. 308. As the Commission said in this case: 'A port is neither the destination nor the origin of traffic passing through it. It levies toll on the traffic, in substantially the same manner as do common carriers, in its charges for the use of its facilities in the transfer of traffic between the rail and water carriers.' Although the shipper in the first instance consigns the commodity to the port and a separate contract is made for ocean carriage, the through rate none the less consists of the rail rate to the port, plus the ocean freight, which is the same from all Gulf ports. 

The choice of route is determined solely by the rail rates from or to the ports. If these are equalized, the shipper has an option; but, if they are disparate, the route through the port taking the higher rate is necessarily excluded. A very slight differential in the rail rate, in some instances as little as a fraction of a cent per hundred pounds, will divert the traffic through the port so advantaged. The application of a distance scale to the rail rate automatically precludes shipment through the more distant port.

Long prior to the passage of the act to regulate commerce the railroads, recognizing this situation, and desiring to hold to their own lines the traffic running to ports which they serve, equalized rates through the ports reached by their own lines with those maintained by their rivals to other ports, or established differentials in favor of their own ports in order to retain a portion of the competitive export business. And a carrier serving two ports has for like reason fixed an equal or lower rate to the more distant of the two, solely to meet the competition of rivals who reached it by more direct routes. These practices have not been indulged either to aid or to harm a port as such, but solely to obtain or retain business for the carrier's own line.  With the abstract fairness of such adjustment neither the Commission nor the courts have any concern. This is not to say, however, that the rates promulgated are beyond the Commission's jurisdiction. While that body has no control over the ocean rate, it has power to compel a reasonable charge for the rail haul. Compare Armour Packing Co. v. United States (C.C.A.) 153 F. 1, 14 L.R.A.(N.S.) 400; News Syndicate Co. v. New York Central R.R., 275 U.S. 179, 186, 187, 48 S.Ct. 39, 72 L.Ed. 225.  As the carriers are in competition for the business, they may, within the zone of reasonableness,  prescribed by the statute, adjust their rates so as to obtain or retain the desired traffic for their own lines. Interstate Commerce Comm. v. Alabama Midland Ry. Co. (C.C.A.) 74 F. 715, 723, 724; Id., 168 U.S. 144, 172, 173, 18 S.Ct. 45, 42 L.Ed. 414; Skinner & Eddy Corp. v. United States, 249 U.S. 557, 564, 39 S.Ct. 375, 63 L.Ed. 772; United States v. Illinois Central R.R., 263 U.S. 515, 522, 44 S.Ct. 189, 68 L.Ed. 417.

The theory of the act is that the carriers in initiating rates may adjust them to competitive conditions, and that such action does not amount to undue discrimination; Texas & Pacific Ry. Co. v. Interstate Commerce Commission, 162 U.S. 197, 16 S.Ct. 666, 40 L.Ed. 940. There the charging of rates on import traffic moving from a port on through bills of lading, much lower than those fixed for domestic transportation, was held not to amount as matter of law to discrimination forbidden by section 3. The carrier showed, in justification of the lower rates on import traffic, that, unless these were permitted, water and rail-and-water competition would divert the traffic away from the port of New Orleans and the carrier's lines extending from that port. Since that decision it has been recognized that export and import shipments, although not made on through bills, might lawfully be transported at rates below those charged for domestic traffic between the same points.  The same purpose not to stifle competition justifies relief under section 4 from the prohibition against charging the same or less for a longer than for a shorter haul. Interstate Commerce Comm. v. Baltimore & Ohio R.R. Co., 145 U.S. 263, 276, 12 S.Ct. 844, 36 L.Ed. 699; Interstate Commerce Comm. v. Alabama Midland Ry. Co., 168 U.S. 144, 164, 18 S.Ct. 45, 42 L.Ed. 414; Louisville & N.R. Co. v. Behlmer, 175 U.S. 648, 671, 20 S.Ct. 209, 44 L.Ed. 309; Inter-Mountain Rate Cases, 234 U.S. 476, 483-485, 34 S.Ct. 986, 58 L.Ed. 1408. And relief under the fourth section has been granted on this ground in respect of export and import rates. Export and Import Rates, 169 I.C.C. 13.

While the carriers may therefore, meet competition by equalizing rates or maintaining differentials both to interior points and to ports, they may not adjust their rates with the motive of injuring or aiding a shipper, a particular kind of traffic, or a locality, for so to do is to depart from the transportation standard, conformity to which the act contemplates, and substitute others which are prohibited. A tariff published for the purpose of destroying a market or building up one, of diverting traffic from a particular place to the injury of that place, or in aid of some other, is unlawful; and, obviously, what the carrier may not lawfully do, the Commission may not compel. Southern Pac. Co. v. Interstate Commerce Comm., 219 U.S. 433, 444, 31 S.Ct. 288, 55 L.Ed. 283; Interstate Commerce Comm. v. Diffenbaugh, 222 U.S. 42, 46, 32 S.Ct. 22, 56 L.Ed. 83; Ellis v. Interstate Commerce Comm., 237 U.S. 434, 445, 35 S.Ct. 645, 59 L.Ed. 1036; United States v. Illinois Central R.R., 263 U.S. 515, 524, 44 S.Ct. 189, 68 L.Ed. 417; Atchison, T. & S.F. Ry. v. Interstate Commerce Comm. (Com. Ct.) 190 F. 591; Anchor Coal Co. v. United States (D.C.) 25 F.(2d) 462, 471. 

1. In the light of the facts exhibited by the record and the principles underlying the act, are ports, in respect of export, import, and coastwise traffic, localities susceptible of undue preference or prejudice within the meaning of section 3? The purpose of sections 2, 3, and 4 (49 USCA §§ 2-4), as exhibited by committee reports and explained by those in charge of the bill in Congress, was to prevent unjust discrimination resulting from existing practices. Similar commodities were, without reason or excuse, carried at different rates. Shippers similarly situated were put on unequal terms. Producers and consumers at points of origin and destination were prejudiced by unequal treatment in the matter of rates or service. Obviously localities of origin or destination might also be prejudiced by undue discrimination. One of the most prevalent and reprehensible practices at which the act was aimed was the charging of a less or an equal rate for a longer haul upon the same line or route. The act was passed for the protection of those who pay or bear the rates. The standards it establishes are transportation standards, not criteria of general welfare. The word 'localities,' therefore, has its proper office as denoting the origin or destination of traffic and the shipping, producing, and consuming areas affected by rates and practices of carriers. The phrase was, however, not intended to cover a junction, a way station, a gateway, or a port, as respects traffic passing through it.

Considered as points of origin or destination, any or all of these are localities within the purview of the section. All of them may, moreover, though not considered as localities served, be involved in acts of discrimination. The situation here presented furnishes a close analogy to proportional rates or combination rates, and with respect to either of these the charge on shipments through a given gateway or port may discriminate against traffic passing through another so as to deprive a shipper of his right of choice of route through either.  In such case, however, the discrimination operates upon the shipper, not upon the port. There are through rates, proportional rates, and combination rates, applicable to traffic routed through river crossings and gateways. It seems too plain for argument that the Commission has no authority, upon a showing by a gateway that under an existing tariff too much traffic passes through another, or too little thr ugh it, to readjust the rates and prescribe differentials so as to divert traffic through the complaining gateway. The interests and industries of a gateway are not entitled thus to obtain a benefit reflected from additional traffic which would be diverted by such action of the Commission. We perceive no difference in principle as to export or import traffic routed through ports.

The legislative history of the act demonstrates that Congress did not intend to forbid the equalization of export or import rates by lines serving several ports in order to meet competition. These rates, it was said, were not to be proportioned to the respective distances between inland origins or destinations and the ports.  Both equalizations and differentials had for some time been maintained in the rates to various Atlantic ports. Congress was aware of this, and had no intention of interfering with the maintenance of these rate adjustments.

Appellees say, however, that the Commission has always treated ports as localities within the meaning of section 3, and exercised the power to abate discrimination by prescribing differentials in export rates. They add that, though the act has been several times amended, this section has been retained in its original form, and Congress has thus sanctioned the Commission's interpretation. Where a statutory body has assumed a power plainly not granted, no amount of such interpretation is binding upon the courts. Interstate Commerce Comm. v. C., N.O. & T.P. Ry. Co., 167 U.S. 479, 510, 17 S.Ct. 896, 42 L.Ed. 243. This we think is the situation here presented, for, as we have said, the word 'localities' is used with reference to places of origin and destination; its employment is not intended to permit the Commission, in its discretion, to favor or hamper a community having no such relation to the service of transportation.

Moreover, we do not find that any such settled construction had been adopted or that Congress intended to sanction it. With few and occasional exceptions the Commission has not until a recent date essayed to prescribe differentials in export rates. Prior to the Hepburn Amendment in 1906 (34 Stat. 584), port differentials were considered in three cases.  In the first certain carriers applied for leave to equalize their export rates to Boston with those charged to New York. The petitions were dismissed on the ground that the Commission should not authorize what the carriers might lawfully do without permission. In the second, a New York trade association complained that the maintenance of differentials in export rates to Philadelphia and Baltimore voluntarily established by the carriers worked undue prejudice against New York. The Commission found they did not result in undue prejudice; though it treated the ports as localities which would be entitled to relief under a proper showing. In the third case shippers and carriers serving north Atlantic ports submitted to the Commission the question of the fairness of the current differentials, and that body acted merely as an arbitrator and not in its official capacity.

The legislative history of the Hepburn Amendment discloses a clear intent not to confer power to circumscribe the adjustment of export and import rates by the carriers to meet competition.  The expressions used disclose no thought that the Commission had held the contrary. 

Between the dates of the Hepburn Amendment (34 Stat. 584) and the Transportation Act 1920 (41 Stat. 456), the Commission had before it two cases relevant to the power to prescribe port differentials.  In the first the Commission recognized its lack of power to deal with the relationship of the rates.  In the second the complaint was that Astoria was prejudiced by exaction of higher export rates from origin territory than those to Seattle and Tacoma. Though the haul to Astoria was longer, the Commission required equalization. The Commission in this case asserted its authority to deal with export rate relationship solely in the interests of the affected ports. Whether the order made was within the competence of that body or not, the important fact is that it did not prescribe differentials, but in the interest of competition opened the three ports to export shipment on equal terms. 

We think that at the date of the passage of the Transportation Act no such administrative practice had been established as to require the conclusion that in failing to amend section 3 the Congress approved any asserted power to adjust export and import rates in the interests of the ports alone.

It remains to determine whether since 1920 there has been such a uniform and repeated assertion of this authority as would constrain us to adopt the principle. The instances in which the Commission has considered export and import traffic fall into several classes: First, where shippers' complaints concerning port differentials established by carriers were dismissed,  or were found justified and prejudice ordered removed;  secondly, where, on shippers' complaint against differentials, equalization of rates was ordered;  thirdly, where on complaint by a port differentials voluntarily established by the carriers were altered.  These are not relevant to the present controversy. In two decisions rendered prior to the instant one the Commission, on complaint of port interests, exercised the supposed power to compel the establishment of differentials as between ports.  But we are not persuaded these rulings form a body of administrative action sufficient to overthrow the evident purpose of section 3.

We conclude that ports as such are not localities with respect to export and import traffic routed through them, susceptible of undue preference or prejudice within the intent of the act.

While the Commission's jurisdiction of port rate relation was fully argued, the appellees seek to support the orders under the power to abate discrimination between persons and shippers. The argument is based upon averments of the complaint as to prejudice of persons at Galveston. There is, however, no allegation that shippers or consignees in the interior are prejudiced or preferred by the equalization of the New Orleans rates with those to the Texas ports, and the Commission made no finding of preference or prejudice of shippers or consignees, or localities of origin and destination.  It compared at great length the facilities of the ports, their volume of traffic, the relative growth of their export and import business, their respective steamship facilities, and reached the conclusion that, though relative distance is not conclusive and competitive conditions are to be regarded, the Texas ports are entitled to an advantage in rate consequent upon the shorter haul to and fr m the interior territory. The Commission's three reports abound with statements that a differential in favor of the Texas ports will divert traffic running to New Orleans and send it through the Texas ports. Petroleum is one of the commodities as to which complaint was made. There is no transportation difference discoverable in the record between this traffic and that of the other freights affected by the order. But the Commission concluded that New Orleans was not receiving more than its fair share of this business, and that a differential advantage would be of little benefit to the Texas ports by diverting this commodity to them, and therefore refused to make any order respecting the rates on petroleum and its products.  It has since, apparently upon similar considerations, refused to prescribe differentials in the rates on blackstrap molasses.  The actual basis of the decision is, moreover, avowed by the Commission. In the first report it said:

'We find that the present relationships of the assailed rates on export, import, and coastwise traffic, * * * are unduly prejudicial to Galveston and unduly preferential of New Orleans.' 100 I.C.C. 122.

'We find that the present parity of rates as between the Texas and Louisiana ports * * * does not result in substantial injury to the Texas ports in respect of petroleum and its products, but does result in substantial injury to and prejudice against the Texas ports in respect of the other commodities considered. * * *' 128 I.C.C. 388.

'Upon further consideration we now find * * * that the present relationships of the assailed carload rates on export, import, and coastwise traffic * * * are, and for the future will be, unduly prejudicial to Galveston and the other Texas ports taking the same rates, and unduly preferential of New Orleans.' 160 I.C.C. 359.

The action of the Commission cannot be justified upon any theory that it was protecting shippers and consignees, who would naturally desire all possible routes for foreign shipment. On the contrary, the orders prohibited a practice born of competition, and not proved to involve a loss of revenue to the appellants. The plain purpose of the orders was to build up the Texas ports by diverting export and import traffic to them. As we have shown, section 3 grants no such power.

2. The Commission's action is challenged for another and wholly independent reason, which, if sustained, also requires a reversal of the decree. By its second order the Commission excluded the Texas & Pacific and the L.R. & N. from its findings of undue preference and prejudice and exempted them from the requirement as to differentials. The Texas & Pacific had been included by the first order on the theory that it was part of the Missouri Pacific system which served both New Orleans and the Texas ports. Upon rehearing the conclusion was that the line was independently operated. Exemption was thereupon granted both appellants pursuant to a rule which the Commission had consistently followed since its organization: namely, that a carrier may not be held responsible for undue prejudice or preference unless both of the localities affected are upon its lines, or it effectively participates in the rates to both. In the final report these roads were denied exemption under the belief that this court had held the principle inapplicable in the circumstances here disclosed. The appe lants insist the rule is a reasonable one, consonant with the purposes of the act, and that our decisions have not narrowed it so as to exclude this case from its scope.

The line of the Texas & Pacific in Texas is intersected at intervals of about 40 miles by north-and-south lines directly or indirectly serving the Texas ports. The population of these junction points is over ten times as great as that of all other open stations on this appellant's line in Texas, and the greater volume of export and import traffic originates and terminates at the junctions.  Thus the question is whether the Texas & Pacific may continue to participate in the handling of the traffic moving through the ports to and from points on its own rails, on an equality of rates with competing lines which extend to the Texas ports, or may be forbidden so to do because it is a party with the competing carriers to joint rates from stations on its own line to the Texas ports. The same issue is presented with respect to the L.R. & N. Neither of the appellants controls the rates to the Texas ports, and the Commission so finds.  Though the Texas port lines can reduce their rates to and from those ports without the concurrence of the New Orleans lines, no reductions can be made in those rates by the New Orleans lines, even from or to their local stations, without the concurrence of one or more lines reaching the Texas ports. Clearly the New Orleans carriers have no effective control over the rates between their junction points and the Texas ports. As respects local stations, their participation in joint rates with the lines to Texas ports is required by section 1(4) of the act (49 USCA § 1(4); but such rates may not be higher than reasonable maxima fixed by national or state authority nor lower than the amount agreed to by their connections to the Texas ports. The appellants insist that their compulsory participation in rates to and from the Texas ports has no legal significance, and the question remains whether they in fact exercise effective control over those rates.

The classical case of discrimination in rates is presented where a single carrier serving two points approximately equidistant from a common origin on the carrier's line exacts unequal rates for the two hauls. Not only is the prejudice obvious, but equally so the ability of the carrier to abate it by raising the rates to the point enjoying the lower rates, or decreasing those to the point subject to the higher charge. The principle comprehends, as well, instances of joint rates where the same carriers participate in the rates to both points,  and where the originating (or delivering) carriers are different, but the delivering (or originating) carriers are the same.  So, too, a carrier may be responsible for preference or prejudice where it participates in one of several through routes between point of origin and the prejudiced destinations, although its own line may reach only one or neither of the latter, St. Louis S.W. Ry. v. United States, 245 U.S. 136, 38 S.Ct. 49, 62 L.Ed. 199, for the discrimination is brought about by the disparity of rates, and the order requiring its abatement necessarily runs against all the carriers parties to them.  f one or more of the railroads whose lines make up the through route should refuse, upon an order to equalize rates, to afford one of the others a proper division of the rate, the latter may obtain redress from the Commission under section 15(6) (49 USCA § 15(6). Where, however, a carrier whose lines reach, or which controls the rate to, one of the destinations, is a party to a joint rate to the other but cannot make or control the latter rate, or though it were to withdraw as a party thereto, or to cancel the rate, the discrimination would still continue-it cannot be held responsible, nor can any order to remove the prejudice run against it.  This rule has been consistently applied in respect of export and import rates to the ports.  The reason for the doctrine is that preference or prejudice can be found only by a comparison of two rates. If these are the rate of one carrier to point A and that of another to point B while a relationship of one to the other may be determined, neither the first nor the second carrier alone can be held to have created the relation. Assuming that neither rate is unreasonable, the one carrier cannot be compelled to alter its rate, because the other's is higher or lower for the same service. A carrier or group of carriers must be the common source of the discrimination-must effectively participate in both rates, if an order for correction of the disparity is to run against it or them. Where an order is made under section 3 an alternative must be afforded.  The offender or offenders may abate the discrimination by raising one rate, lowering the other, or altering both. Compare American Express Co. v. South Dakota ex rel. Caldwell, 244 U.S. 617, 624, 37 S.Ct. 656, 61 L.Ed. 1352; United States v. Pennsylvania R. Co., 266 U.S. 191, 45 S.Ct. 43, 69 L.Ed. 243; Chicago, I. & L. Ry. Co. v. United States, 270 U.S. 287, 292, 46 S.Ct. 226, 70 L.Ed. 590; Minneapolis & St. L.R. Co. v. Peoria & Pekin U.R. Co., 270 U.S. 580, 582, 46 S.Ct. 402, 70 L.Ed. 743. The situation must be such that the carrier or carriers, if given an option, have an actual alternative.

The principle has been approved in decisions of this court with respect to practices, Interstate Commerce Comm. v. Diffenbaugh, 222 U.S. 42, 32 S.Ct. 22, 56 L.Ed.  3; Central Railroad of New Jersey v. United States et al., 257 U.S. 247, 42 S.Ct. 80, 66 L.Ed. 217, and rates, East Tenn., V. & G. Ry. Co. v. Interstate Commerce Comm., 181 U.S. 1, 21 S.Ct. 516, 45 L.Ed. 719; Penn Refining Co. v. Western N.Y. & P.R.R. Co., 208 U.S. 208, 221, 28 S.Ct. 268, 52 L.Ed. 456.

In the Central Railroad Case it was said [page 259 of 257 U.S., 42 S.Ct. 80, 83, 66 L.Ed. 217]: 'But participation merely in joint rates does not make connecting carriers partners. They can be held jointly and severally responsible for unjust discrimination only if each carrier has participated in some way in that which causes the unjust discrimination, as where a lower joint rate is given to one locality than to another similarly situated. (Citing cases.) If this were not so, the legality or illegality of a carrier's practice would depend, not on its own act, but on the acts of its connecting carriers. * * * What Congress sought to prevent by that section (3) as originally enacted was not differences between localities in transportation rates, facilities, and privileges, but unjust discrimination between them by the same carrier or carriers.' While this language was used with respect to circumstances differing from those here disclosed, it applies to the situation of appellants, who are by the Commission's order held responsible for what is not and cannot be the result of their own acts-the level of the rates to the Texas ports.

In the East Tennessee Case the court said (page 18 of 181 U.S., 21 S.Ct. 516, 522, 45 L.Ed. 719):

'The prohibition of the 3d section, when that section is considered in its proper relation, is directed against unjust discrimination or undue preference arising from the voluntary and wrongful act of the carriers complained of as having given undue preference, and does not relate to acts the result of conditions wholly beyond the control of such carriers.'

The appellees contend, however, and the Commission concluded that in later cases the court has held the principle inapplicable in circumstances so like those here exhibited that it should not control our decision in the instant case. One of these is St. Louis S.W. Ry. Co. v. United States, 245 U.S. 136, 38 S.Ct. 49, 62 L.Ed. 199, cited for the proposition that the Commission has power to prevent carriers which participate in rates from blanket territory from discriminating against a particular destination, although one of them does not with its own lines reach such destination, but bills through traffic to it over connecting lines. The order there under review was for the establishment of a reasonable joint rate, or in the alternative new through routes with joint rates, under section 15 of the act, and was held by this court to be primarily an order under that section, and not under section 3. The statement with respect to the possibility of unjust discrimination by all the participating carriers, even though the rails of some did not reach the locality prejudiced, is clearly sound, but is beside the point here in issue; for in that case no question as to the control of the rate to both points by any carrier affected by the order was raised or decided.

Chicago, I. & L. Ry. Co. v. United States, 270 U.S. 287, 46 S.Ct. 226, 228, 70 L.Ed. 590, is relied upon because of the statement in the opinion that, 'wherever discrimination is, in fact, practiced, an order to remove it may issue, and the order may extend to every carrier who participates in inflicting the injury.' This was said with respect to a mandate to three carriers serving Michigan City, each of which had refused to enter into interchange arrangements with an electric railroad. Their lines did not connect directly with the electric line, but required for interchange the service of an intermediate switching carrier. The order of the Commission was held proper because each defendant railroad was solely responsible for the prejudice resulting from its own refusal to maintain interchange arrangements with the electric line, and for the preference of maintaining such arrangements with other carriers at Michigan City. Each could, without reference to the conduct of any other, correct the unjust discrimination which it individually practiced. The very question here is whether the New Orleans lines in fact control the rates to the Texas ports, and the Commission has answered it in the negative.

Principal reliance is placed upon United States v. Ilinois Central R.R., and Wyoming Ry. Co. v. United States, 263 U.S. 515, 44 S.Ct. 189, 68 L.Ed. 417. In the first it appeared that the Illinois Central equalized rates on lumber to certain destinations from all its main and branch line points in blanket origin territory, and from points on certain independent short lines within the blanket area, but refused to extend similar blanket rates to producing points on the Fernwood & Gulf, an independent short line serving the same area. The Illinois Central's excuse was that it could not afford to shrink its earnings by larger divisions to the Fernwood & Gulf. The complaint before the Commission was against both carriers, and the Commission required that both should abate the unjust discrimination. 

In the second case it was shown that the Burlington published a blanket rate on lumber to destinations on a portion of its main line and to points located on its branch lines, but refused to join in an equal rate to a point on an independent branch line connected with the blanketed portion of the main line. The service to the latter point at the higher combination rate was less than was rendered to points on the Burlington's branch lines. The Commission ordered both carriers to abolish the undue preference and prejudice. 

It will be noted that in the one case the Illinois Central and in the other the Burlington made the one rate and was a party to the other. Not only so, but in each case the trunk line carrier controlled the joint or combination rate to or from the prejudiced locality. Quite clearly the independent line could not equalize that rate with the one in force to the preferred locality without the concurrence of the trunk line. Both railroads joined in the bill to enjoin enforcement of the order in the Illinois Central Case, but only the independent carrier filed the bill in the Burlington Case.

The appellees insist that, as the orders ran against the independent road as well as the trunk line, and this court refused to set them aside, it necessarily follows that a carrier may be liable for unjust discrimination by virtue of its mere participation in one of the rates whether or not it controls that rate. The argument ignores the substance and basis of the decision. The trunk line controlled both rates, and by its action alone could the disparity be corrected. But the short line was a party to one of the rates which created the illegal relation; and was therefore properly joined in the order. Compare Virginian Ry. Co. v. United States, 272 U.S. 658, 665, 47 S.Ct. 222, 71 L.Ed. 463. The fact, however, that the order included the short line is entirely insignificant on the question whether the same carrier in fact controlled both rates and was, in fact, responsible for the undue preference and prejudice. The contention of the short line that it did not participate in the discrimination because it did not join in the lower rates to the preferred locality maintained by the Illinois Central, and could not, therefore, by its own act, remove the discrimination, was properly overruled. As said by the court, that carrier, in joining the Illinois Central in establishing the prejudicial through rate, was as much a party to the discrimination as if it had also joined in the lower rates to the other points alleged to be unduly preferred. If Fernwood & Gulf could not persuade the Illinois Central to join in a new nondiscriminatory rate and accord it a proper division,  t had a plain remedy under section 15 of the act. To make the decision a precedent for the instant case, it would have to be found that the New Orleans carriers effectively controlled both the rates to New Orleans and those to the Texas ports. If they did, obviously, an order might run, not only against the New Orleans carriers, but against their connections to the Texas ports, albeit the latter did not control those rates.

We find nothing in any of the decisions which renders inapplicable the principle upon which the Commission has acted, with the approval of this court, for more than forty years in the administration of section 3, and conclude that the New Orleans lines could not properly be held guilty of unjust discrimination against the Texas ports, in the absence of a finding of effective participation in the rates to them.

3. The conclusions announced render it unnecessary to consider the other questions pressed by the appellants.

The judgment must be reversed and the cause remanded to the District Court for further proceedings in conformity with this opinion.

It is so ordered.

Mr. Justice STONE, dissenting.

The Interstate Commerce Commission, acting under section 3(1) and section 15(1), of the Interstate Commerce Act, 24 Stat. 379, as amended by Transportation Act, 1920, 41 Stat. 456 (49 USCA §§ 3(1), 15(1), after extensive investigation, has found that the rates of rail carriers on commodities moving in import, export, and coastowise transportation from or to points in Texas, Oklahoma, and Southern Kansas, and in Louisiana west of the Mississippi river were unduly prejudicial to Galveston and other Texas gulf ports and unduly preferential of New Orleans. Its order, framed to restrict, but not to remove entirely, the discrimination, sustained by the District Court of three judges below, is now held void and set aside by this Court. I think that the order is within the competency of the Commission, is supported by the evidence, and should in all respectrs be upheld.

Stated generally, the discrimination complained of is the maintenance of rates by the rail carriers which give no recognition to the proximity of Galveston and other Texas ports to the interior points involved. The rates thus deprive the Texas ports of the natural advantage of their geographical position over that of a rival port, New Orleans; and, as the commercial advantages of New Orleans exceed those of the Texas ports, the rates result in the diversion of traffic to the former from territory normally tributary to the latter. The Commission found that, although the length of haul from the interior shipping points to the Texas ports is less than that to New Orleans, that difference varying from 162 to 213 miles from typical points,  the carriers have long maintained the same, and in many instances substantially lower rates to New Orleans. In territory nearer to New Orleans than to the Texas ports, the lesser service has, on the other hand, been given recognition by correspondingly lower rates. The Commission has found, and it is not questioned, that transportation costs and conditions throughout the southwest territory are substantially the same; that the rates established by the carriers disregard generally and materially the amounts and costs of service; that the discrimination has deprived, and will continue to deprive, the Texas ports of the natural advantage of their more favorable geographical position, and has resulted, and will continue to result, in building up the port of New Orleans to their detriment and at their expense. The order assailed seeks to curtail this discrimination and the injury which it inflicts. It leaves undisturbed the lower rates in force to New Orleans from points nearer that city than Galveston, and permits parity of rates where the distance to New Orleans does not exceed that to Galveston by more than 25 per cent., but for differences in distance exceeding 25 per cent. it has named minimum differentials under the rates mai tained to New Orleans.

In holding that the Commission is without power to make the order, the Court does not deny that a discrimination which is produced by charging equal rates for unequal service is prohibited by the statute as much as one resulting from unequal rates for equal service. Compare The Shreveport Case, 234 U.S. 342, 346, 34 S.Ct. 833, 58 L.Ed. 1341. Nor does the Court consider material, in this respect, the findings of the Commission that the rates to Texas ports and New Orleans are both reasonable to shippers, in that the former are not too high, or the latter so low as to cast a burden on other traffic. For it is not denied that the Commission may remove a discrimination effected by rates which are within the zone of reasonableness if the discrimination is one forbidden by section 3(1) of the act. American Express Co. v. South Dakota ex rel. Caldwell, 244 U.S. 617, 37 S.Ct. 656, 61 L.Ed. 1352; United States v. Illinois Central Ry. Co., 263 U.S. 515, 524, 44 S.Ct. 189, 68 L.Ed. 417. It is not suggested that a discrimination effected by reasonable rates may not result in gross injury to the locality discriminated against; and the opinion does not question the correctness of the findings here that such injury is inflicted on the Texas ports by the prohibited rates. The issue is thus narrowed to two questions, first, whether the acts of Congress giving broad powers to the Commission to remove discriminations resulting in undue or unreasonable prejudice to a 'locality' have conferred any power on the Commission to curtail an unduly prejudicial discrimination against a port, and, second, whether, assuming that the Commission has such power, it may order the removal of the discrimination by the appellant carriers who participate in the discriminatory rates, although their rails reach only New Orleans, and not the Texas ports.

First. The Court holds that this power is lacking because the locality injured by the discrimination, a port, is neither the origin nor the ultimate destination of the traffic involved, but a gateway through which it passes, albeit it is arrested there pending its transshipment upon a new and independent contract for ocean transportation. It is said that a gateway is not a 'locality' within the meaning of the act because it was never intended that the statute should forbid discrimination against localities which are not points of origin or ultimate destination, however unreasonable and unjust the discrimination may be.

The words of the statute neither state nor suggest such an exception.

Section 3(1) of the Interstate Commerce Act (49 USCA § 3(1) declares:

That 'it shall be unlawful for any common carrier * * * to make or give any undue or unreasonable preference or advantage to any particular person, company, firm, corporation, or locality, or any particular description of traffic, in any respect whatsoever, or to subject any particular person, company, firm, corporation, or locality, or any particular description of traffic, to any undue or unreasonable prejudice or disadvantage in any respect whatsoever.'

Section 15(1), 49 USCA § 15(1), gives to the Commission plenary power to remove any such 'unjustly discriminatory or unduly preferential' individual or joint rate, by ordering the carrier or carriers to cease and desist from the violation, and by prescribing a just and reasonable individual or joint rate to be observed by the carrier or carriers concerned. On its face the prohibition of any undue and unreasonable prejudice to 'any particular locality,' 'in any respect whatsoever,' soever,' would seem so plainly to include a port as to leave no room for construction. Compare United States v. Shreveport Grain & Elevator Co., 287 U.S. 77, 53 S. t. 42, 77 L.Ed. 175; Crooks v. Harrelson, 282 U.S. 55, 51 S.Ct. 49, 75 L.Ed. 156; Van Camp & Sons v. American Can Co., 278 U.S. 245, 253, 49 S.Ct. 112, 73 L.Ed. 311, 60 A.L.R. 1060.

I can find nothing in the purpose or history of the statute which suggests that it means any less than it says. This Court has often declared that the purpose of the all-embracing language of the statute was to suppress every form of unreasonable discrimination which it was within the power of Congress to condemn. Merchants' Warehouse Co. v. United States, 283 U.S. 501, 512, 51 S.Ct. 505, 75 L.Ed. 1227; Louisville & Nashville R.R. Co. v. United States, 282 U.S. 740, 749, 750, 51 S.Ct. 297, 75 L.Ed. 672; The Shreveport Case, supra, 234 U.S. 356, 34 S.Ct. 833, 58 L.Ed. 1341; Louisville & Nashville R.R. Co. v. Mottley, 219 U.S. 467, 31 S.Ct. 265, 55 L.Ed. 297, 34 L.R.A.(N.S.) 671. It has said that discrimination was the principal thing aimed at, and 'the purpose of Congress was to cut up by the roots every form of discrimination, favoritism, and inequality.' Louisville & Nashville R.R. Co. v. Mottley, supra, 219 U.S. 478, 31 S.Ct. 265, 269, 55 L.Ed. 297, 34 L.R.A.(N.S.) 671.

Statutory language so unambiguous and a purpose so comprehensive do not readily yield to the conclusion that a locality which is a port is not a 'locality' within the meaning of the act. The bare fact that a port is a gateway and not the ultimate destination of the traffic does not support that conclusion, for the commercial interests of a port, always of great magnitude, may suffer the same destruction from discriminatory rates as do shippers or other industrial interests at points of origin or destination. A rate structure which diverts from one port to another a portion of the ocean-borne traffic, which would otherwise naturally pass through the former, sufficient to destroy the business of banks, marine insurance companies, freight forwarders, freight and ship brokers, stevedores, tonnage companies, pilots, dry docks, ship supply and bunker coal merchants, customs brokers, export and import commission houses, centered there, would seem to have an effect upon the commerce and general welfare of the country of precisely the kind which the act was intended to prohibit and the Commission empowered to prevent. So the Commission has concluded in a series of cases dealing with discrimination against ports, going back to the first years of its existence. See New York Produce Exch. v. B. & O.R.R. Co., 7 I.C.C. 612, 658, 660; In re Export and Domestic Rates, 8 I.C.C. 214; In re Differential Rates, 11 I.C.C. 13; Chamber of Commerce of N.Y. v. New York Central & H.R.R. Co., 24 I.C.C. 55; Id., 27 I.C.C. 238; Astoria v. S., P. & S. R. Co., 38 I.C.C. 16; In re Import Rates, 24 I.C.C. 78; New York Harbor Case, 47 I.C.C. 643; Mobile Chamber of Commerce v. Mobile & O.R. Co., 57 I.C.C. 554; Coffee from Galveston, Tex., and other Gulf Ports, 58 I.C.C. 716; Id., 64 I.C.C. 26; Charleston Traffic Bureau v. Ala. G.S.R. Co., 89 I.C.C. 501; Maritime Ass'n of Boston Chamber of Commerce v. Ann Arbor R. Co., 95 I.C.C. 539; Oswego v. B. & O. R. Co., 151 I.C.C. 717.

This administrative practice and construction cannot be dismissed with the observation that where 'a statutory body has assumed a power plainly not granted no amount of such interpretation is binding upon the court,' for the question obviously is whether or not a power was granted which the language of the statute plainly embraces and which certainly was not plainly denied. In determining that question when the meaning of the statute is doubtful on its face, we have often said that administrative construction is of persuasive force, see United States v. Chicago, North Shore & Milwaukee R.R. Co., 288 U.S. 1, 53 S.Ct. 245, 77 L.Ed. 583; New York, N.H. & H.R.R. Co. v. Interstate Commerce Commission, 200 U.S. 361, 401, 26 S.Ct. 272, 50 L.Ed. 515, particularly where, as here, the statute has been frequently amended and the provision relied upon retained in identical form. Compare Brewster v. Gage, 280 U.S. 327, 336, 50 S.Ct. 115, 74 L.Ed. 457; National Lead Co. v. United States, 252 U.S. 140, 147, 40 S.Ct. 237, 64 L.Ed. 496. This construction certainly cannot be summarily disregarded in favor of another which departs both from the plain meaning of the words and from the policy which has hitherto been thought to have inspired their use.

To support such a departure it is said that, as the railroads, before the enactment of the statute, had in some instances attempted to equalize competing ports by setting up a rate structure which did not conform wholly to the carrier service involved, and as Congress, in the Interstate Commerce Act, evinced no intention to prevent competition for business between rail carriers, it could not have intended by this legislation forbidding discrimination prejudicial to localities to forbid discriminations between rival ports, however unreasonable and injurious.

The port differentials and equalizations maintained prior to the passage of the original act, in order to secure a fair distribution of traffic among the Atlantic ports and the carriers serving them, were very different in quality and prejudicial effect upon the localities concerned from the rate structure resulting in the discrimination disclosed here.  The existence of those equalizations before 1887 and the fact that in some instances since that date they have been regarded as innocuous even by the Commission itself can hardly lend support to the supposition that the statute was not intended to forbid destructive discriminations in that form as well as in any other. The argument seems to be that the statute cannot be deemed to forbid unjust discriminations against ports since, if it did, all rates to competing ports not measured by mileage or carrier service would be forbidden whether unjust or not. With equal plausibility it was argued that, because competition between carriers was an established practice before the enactment of section 3 and is not forbidden by the act, no discrimination induced by carrier competition was forbidden. But that construction was rejected by this Court, Wight v. United States, 167 U.S. 512, 517, 17 S.Ct. 822, 42 L.Ed. 258; United States v. Illinois Central R.R. Co., supra; Merchants' Warehouse Co. v. United States, supra, for the same reason that the present construction should be rejected-that, although carrier competition was not destroyed by the Interstate Commerce Act, it was limited by the prohibition of section 3 of those discriminations which, in the light of all the circumstances, are found to be undue or unreasonable.

The statute does not purport to prohibit all discriminations. It reaches only those against either localities or shippers which result in prejudice which is 'undue or unreasonable.' Cf. Nashville, C. & St. L. Ry. v. Tennessee, 262 U.S. 318, 322, 43 S.Ct. 583, 67 L.Ed. 999. Hence, in determining whether a discrimination involved in a port equalization is 'undue or unreasonable' competition is a factor which may not be ignored (see Interstate Commerce Commission v. Alabama Midland Ry., 168 U.S. 144, 170, 18 S.Ct. 45, 42 L.Ed. 414), the Commission is not to leave out of account either past history or practical experience, or the effect of the discrimination on the ports concerned. But, even though  he exigencies of competition may be entitled to greater consideration in a case of discrimination between ports than in one of discrimination between shippers, the weight which is given to it and to the other relevant facts, in determining whether the discrimination is so unjust as to be forbidden, does not go to the Commission's power but to the propriety of its exercise. United States v. Illinois Central R.R. Co., supra, 263 U.S., 525, 44 S.Ct. 189, 68 L.Ed. 417; Interstate Commerce Commission v. Alabama Midland Ry., supra. That the Commission so conceives its powers and function in considering a rate adjustment equalizing ports is apparent from its statement of the problem in the present case:

'Such an adjustment necessarily disregards distance and commercial instead of natural advantages control. We have consistently refused to condemn such an adjustment where it is shown to serve the best interests of the public, but where, as here, it builds up one port at the expense of another equally favored by natural advantages from the origin territory here considered, a line must be found beyond which distance may not be disregarded.'

This language of the Commission appears to me to suggest the only reasonable interpretation of the statute consonant with its language, its history, and its background. The statute does not command, or the Commission's order direct, that the rates shall be measured exclusively by mileage or carrier service; carrier competition for business passing through gateways or elsewhere is not forbidden, but, when the discrimination goes so far beyond the line of reasonableness as to result in the commercial destruction of a locality, the Commission may declare it 'undue or unreasonable,' and therefore forbidden by the statute, whether aimed at ports or points of shipment or destination. Nothing that this Court has ever said is inconsistent with this conclusion. The legislative history of the statute seems to support, rather than to deny, it.

Close scrutiny of the legislative history of the original act and of the Hepburn Amendment (34 Stat. 584) fails to disclose any intention to except from the forbidden discriminations against localities, undue or unreasonable discriminations against ports. Senator Cullom, who was in charge of the earlier bill, made no reference to the present question in his explanatory statement,  cited in the opinion of the Court,  and none is to be found in the House proceedings to which reference is also made.  Senator Cullom emphasized the fact that the discriminations forbidden included those against localities, and nowhere suggested any exceptions. Mention in the Report of the Senate Committee of the investigation of a committee of the British Parliament and the quotation of its conclusions,  are without significance here. Those conclusions were not indorsed by the Senate Committee and did not deal with undue discriminations produced by railroad competition. It is true that in the debates in Congress on the Hepburn Amendment it was pointed out in several instances that the bill did not confer on the Commission the general power to fix differentials to ports or to any other points,  but it was also pointed out that 'section 3 of the original act (24 Stat. 380) applies just the same. We have not undertaken to amend, limit, or extend section 3. Whatever is unjust and discriminatory under section 3 is unjust under the provisions of this bill, and such will be prohibited. * * *'  Moreover, the basis for this want of power to fix differentials was not that a port is not a 'locality' within the meaning of section 3, but that differential rates on different roads cannot be fully controlled without the fixing of a minimum rate.  And it was recognized in the decisions of this Court prior to the enactment of Transportation Act 1920, conferring the power to fix minimum rates, that unjust discriminations produced by the relation of rates charged or participated in by the same carrier might be forbidden by the Commission by lowering the higher rate (compare St. Louis S.W. Ry. Co. v. United States, 245 U.S. 136, 144, 38 S.Ct. 49, 62 L.Ed. 199) or by an order which left the carrier free to raise or continue the lower rate; 'the compulsion being that if the low rate is retained, the rate applicable to the locality or article discriminated against must be reduced.' Skinner & Eddy Corp. v. United States, 249 U.S. 557, 566, 39 S.Ct. 375, 378, 63 L.Ed. 772.

Second. The Court also holds that, even if a port is a 'locality' within the meaning of the statute, and prejudicial discriminations against it are forbidden, still the Commission is without power to order the Texas & Pacific Railroad Company and the Louisiana Railroad & Navigation Company to remove the discrimination. Both these lines reach New Orleans with their own rails and both participate in through rates and a full line of joint rates between local and junction points on their own lines and the Texas ports. They thus control the rate to New Orleans and are parties to rates to the Texas ports and to the prejudicial discrimination. Nevertheless, it is said that the Commission is without power to make an order removing the discrimination which does not afford to the carriers an alternative method of removing it, either by lowering the rates to the Texas ports or raising those to New Orleans, and that the present order does not afford such an alternative because of the appellants' inability to control the rates to the Texas ports.

The Commission may, in directing the removal of a discriminatory rate or practice, not otherwise objectionable, allow to the carrier a choice of methods of removing the discrimination by the modification of one rate or practice or the other. By the present order the two carriers are left free to remove the discrimination by raising the New Orleans rate which they control, or by entering into lower joint or through rates with the connecting carriers to the Texas ports-a latitude which may serve the interest of the carriers better than would an order specifically directing them to raise the New Orleans rates. Beyond question these roads can remove the discrimination by raising the New Orleans rates, and it neither appears, nor is it argued, that they cannot remove it by lowering the rates to the Texas ports by agreement with their connecting carriers or, in default of agreement, by reducing their own division and securing a corresponding reduction of the joint rate on application to the Commission under section 15(6), 49 USCA § 15(6). See St. Louis Southwestern R.R. Co. v. United States, 245 U.S. 136, 139, note 2, 38 S.Ct. 49, 50, note 4, 62 L.Ed. 199, 205, note 4; compare United States v. Illinois Central R.R. Co., supra, 263 U.S. 521, 44 S.Ct. 189, 68 L.Ed. 417.

But the statute does not compel the Commission to afford such an alternative or permit an offending carrier to avoid its salutary provisions merely for the reason that, although participating in both the offending rates, it can with certainty control only one. It is true that in cases arising before the enactment of Transportation Act 1920 (41 Stat. 456), by which power was given to the Commission to fix a minimum rate, it could not remove a discrimination by prescribing a minimum rate to one of the competing localities. But it could remove the discrimination by imposing a lower maximum rate, even though a joint rate participated in by the carrier whose rails did not reach the locality discriminated against (compare St. Louis Southwestern Ry. Co. v. United States, supra) or, as already mentioned, it could leave the carriers free to remove the discrimination by raising one or lowering the other. See American Express Co. v. South Dakota ex rel. Caldwell, supra, 244 U.S. 624, 37 S.Ct. 656, 61 L.Ed. 1352; United States v. Pennsylvania Railroad Co., 266 U.S. 191, 45 S.Ct. 43, 69 L.Ed. 243. And now that the Commission has power under section 15(1) to fix a minimum rate it may equally command the removal of the discrimination by directing a rate to be raised, just as where the carrier maintains discriminatory practices the Commission may direct the modification of one and not the other, and is not bound to allow the carrier a choice. Merchants' Warehouse Co. v. United States, supra, 283 U.S. 513, 51 S.Ct. 505, 75 L.Ed. 1227; New York, New Haven & Hartford R.R. v. Interstate Commerce Commission, supra, 200 U.S. 404, 26 S.Ct. 272, 50 L.Ed. 515. The fact that the Commission has given to the carrier an option to remove the discrimination by arrangement with the connecting carriers, through which the traffic reaches the Texas ports, does not afford to the carrier any ground for complaint or impair the power of the Commission to make the order.

The situation here appears to be identical with that presented to this Court in United States v. Illinois Central R.R. Co., supra, and in St. Louis Southwestern Ry. Co. v. United States, supra. In both cases the carriers' rails reached one of the competing points only through its connections. In the first, the order leaving the carrier free to remove the discrimination by raising one rate or lowering the other, and in the second an order requiring the carrier to remove the discrimination by establishing a lower joint rate with its connections, was upheld by this Court. In St. Louis Southwestern Ry. Co. v. United States, this Court said, 245 U.S. 144, 38 S.Ct. 49, 52, 62 L.Ed. 199:

'Carriers insist also that the order is void on the ground, that since their 'rails do not reach Paducah, they cannot be guilty of discrimination against that city.' They, however, bill traffic via Cairo or Memphis through to Paducah in connection with the Illinois Central, thus reaching Paducah, although not on their own rails. And, thereby, they become effective instruments of discrimination. Localities require protection as much from combinations of connecting carriers as from single carriers whose 'rails' reach them. Clearly the power of Congress and of the Commission to prevent interstate carriers from practicing discriminating against a particular locality, is not confined to those whose rails enter it.'

The judgment should be affirmed.

The CHIEF JUSTICE, Mr. Justice BRANDEIS, and Mr. Justice CARDOZO concur in this opinion.

Notes

It was also pointed out that relative rates on different roads were not within the control of the Commission. In discussing differentials, Senator Raynor pointed out that the provisions of the bill 'are limited to discriminations upon the same roads. The words 'unjustly discriminatory' or 'unduly preferential' or 'prejudicial' apply to rates and regulations and practices upon the same road, because there can be no such thing as an unjust discrimination or an undue preference between different roads supplying different territory and terminating at different points. * * * If one road charges an unreasonable rate or a discriminating rate, that would surely not justify the Commission's adjusting the rate between this road and some other road that has no connection with it by law or privity of contract. * * *' Cong. Rec., vol. 40, p. 6683. Read in the light of this statement, there is nothing to support the conclusion of the Court in the other statement of Senator Raynor referred to in the opinion (note 20) that there is no 'power whatever in the Commission to adjust relative rates and strike the proper proportions between them. The ports of the United States, therefore, are not within the jurisdiction of the Hepburn Act. If there is a differential between different ports upon different lines of railroads, there is no provision in this measure that invests the Commission with the right to change it. It has a perfect right, of course, where discrimination exists upon the same line, as if a rate to an inland point compared with a rate to a terminal point is unreasonable or unjustly discriminatory, to prescribe a maximum rate; but it has no right to bring competitive roads struggling for competitive markets within its jurisdiction, and I deny in its entirety the proposition that the Commission could by any exercise of its power, direct or inferential, take away from any railroad its right to charge its own rates, unless the rate is unreasonable or u duly preferential or discriminatory upon its own line.' Cong. Rec., vol. 40. p. 3792.
