Union Bridge Co. v. United States

Mr. Justice Harlan, after making the foregoing statement, delivered.the, opinion of the court. The 'first principal question raised by the defendant is whether the. 18th section of the River and Harbor Act of March 3d, 1899/ is in violation of the Constitution' of the United States as delegating legislative and judicial powers *378 to the head of an-Executive Department of the' Government.-: This question, the Government contends, has been determined-in its favor by the principles heretofore announced by this court, and need not be discussed as if now presented' for the 'first time; In its judicial as well as legal aspects the question is of such importance as to justify a full reference to prior decisions. The earliest case is that of The Brig Aurora, 7 Cranch, 382, which involved the question whether Congress could make the revival of-a law (which had ceased to be in force) depend upon the existence of certain facts to be ascertained by the President and set forth in a proclamation by him. The court said: “We can. see no sufficient reason why the-legislature should- not exercise its discretion in reviving the act of March 1st, 1809, either expressly or conditionally, .as their judgment should direct. . The 19th Section of that act, declaring that it should. Continue .in force -to a certain time, and no longer, could not restrict their power of extending its operation without limitation upon the occurrence of any subsequent combination of events.” Réferring ,to this language, we said in the subsequent case of Field v. Clark, 143 U. S. 649, 683: “This certainly is a decision that it was competent for Congress to make the revival-of an act depend fipon the proclamation of the President, showing the. ascertainment by- hito of the fact that the edicts of certain nations had been so revoked 'or modified that they did not violate the neutral commerce.of the United States. The same principle would apply in the case of the suspension of an act upon a contingency to be ascertained by the President and made known by his Proclamation.” In Wayman v. Southard, 10 Wheat. 1, 43, 45, 46, Chief Justice Marshall delivering the unanimous judgment, of the-court, said that although Congress .could not delegate to the.-courts or to -any other 'tribunals powers strictly, and 'exclusively legislative, and although the-line had not beén-exactly drawn that separates the im.por.tamt subjects which must be entirely *379 regulated by the legislature itself from those of less interest “ in which a general provision may be made, and powers given to those who are to act under such general provisions to fill up the details,” yet “Congress may certainly delegate to others' powers which the legislature may rightly exercise itself,!’ and “ the maker of the law may commit, something to the discretion of the other departments.” In Field v. Clark, just cited, 143 U. S. 649, 680, 683, 691, 692, the quéstion arose as to' the constitutionality of that section of the McKinley Tariff Act of. 1890 which provided for the imposition, in a named contingency (to be determined by the President and manifested by his proclamation), of duties upon sugar, molasses and other specified articles, which the act had placed in the free list. • By that section it was declared that “with a yiew to secúre reciprocal trade with countries producing, the following articles, and for this purpose, on and after the first day, of January, eighteen hundred and'ninety-two, whenever, and so often as the President shall be satisfied that the government of any. country producing and exporting .sugars, molasses, coffee, tea and hides, raw-,and 'uncured, or any of such articles, imposes duties or other en-actions. upon the agricultural' ór other products of the United States, which in view of. the free, introduction of such sugar, molasses, coffee, tea and hides into the United States he may deem to be reciprocally unequal and' unreasonable, he shall have the power and it shall be his duty to suspend, by proclama-, tion to that efféct, the provisions of this act relating to the free introduction of such sugar, molasses, coffee, tea and hides, the production of such country, for. such time as he shall deem just, and in such case and during such suspension-duties shall be levied; collected and paid upon sugar, molasses, coffee, tea and hides, the product of or exportation from such designated, country as follows,' namely.” Here'follows in the act provisions indicating the particular duties to be; collected, after the .President’s proclamation, upon sugars, molasses, coffee, tea, hides, etc. It was contended in the Field case that the *380 above section, so far as it authorized the President, to suspend by proclamation the provisions of the act relating to the free introduction of sugar, molasses, coffee,- etc., was ungonstitu-tional, as'delegating to him both ..legislative, and treaty-making powers. In its consideration of this question the .court/after referring to the case of the Brig Aurora, above cited, examined the numerous precedents in legislation showing to what extent the suspension of certain provisions and the going into operation of other .provisions of an act of Congress had. been made to depend entirely upon the finding or ascertainment by the President of certain facts, to be made known.by his proclamation. The acts of Congress which underwent examination by the court are noted in the margin. 1 The result of that examination of legislative precedents was thus stated: “The authority given to the President by the act of June 4, 1794, to lay an embargo on all ships and vessels in the ports of the United States, ‘whenever, in his opinion, the public safety shall so require,’ and under regulations, to be continued or revoked, ‘whenever he shall think proper;’ by the act of February 9, 1799, to remit and discontinue, for the time being, the restraint's and prohibitions which Congress had prescribed with respect to^commercial intercourse with the French Republic, ‘ if he shall deem it expedient and .consistent with the interest,of the United States,’, and ‘to revoke such order, whenever, in his opinion, the interest of the United States shall require;’ by the act of December 19, 1806, to suspend; for a named time, the operation of the non-importation act of the same year, ‘if in his judgment,the public interest should require it;’-by the act of May 1, 1810, to revive a former act, as to'¡Great Britain or France, if either country had not by a *381 named day so revoked or modified its edicts as not‘ to violate the neutral commerce of the United States;’ by the acts of March 3, 1815, and May- 31, 1830, to declare the repeal, as to any foreign nation, of the several acts imposing duties on the tonnage of ships and vessels, and on goods, wares and merchandise-imported’ into the United States, when he should be 'satisfied’ that the discriminating duties of such foreign nations, ' so far as they operate to Ihe disadvantage of the United States,’ had been abolished; by the-act of-March 6, 1866, to declare" the provisions, of the act forbidding the importation into this country of neat cattle and the hides of neat cattle, to be inoperative, ‘whenever in his judgment’ their importation ‘may be made without danger of the introduction or spread of contagious or infectious disease among the cattle of the"United States;’ must be regarded as unwarranted by the Constitution, if the contention of the appellants, in respect to' the third section of the. act of October 1, 1890, be sustained.” Touching the general'question the court said: “That Con-’ gress cannot delegate legislative power to the President is a principle universally recognized as vital to the integrity and maintenance of the system of government ordained by the Constitution. The act of October 1, 1890, in the particular under .consideration, is not inconsistent with that principle. It does’ not, in any real sense, invest the President with the power of legislation. For the purpose of . securing reciprocal trade with countries producing and exporting sugar, molasses; coffee, tea and hides, Congress itself determined that the provisions of the act of October 1, 1890; permitting the free introduction of such articles, should be suspended as to any country producing and exporting them that Imposed exactions and duties on the agricultural and other products of the United States, which the President .deemed, that-is, which he found to- be, reciprocally unequal and unreasonable: CongréSs itself prescribed, in advance, the- duties to be levied, collected and paid, on sugar, molasses, coffee, .tea or hides, produced by or exported from such designated country, while the suspension' *382 lasted. Npthing involving the expediency or'the just operation of such legislation was left to the determination of the President. The words, ‘he may deem/ in the third section, of course, implied that the President would examine, the commercial regulations of other countries producing and exporting sugar, molasses,, coffee, tea and hides, and form a judgment as to whether they were reciprocally equal and reasonable, or the contrary, in their effect upon American products.. But when he ascertaiiied the fact that, .duties and- exactions, reciprocally unequal and. unreasonable, wére imposed upon the agricultural or other products of the United States by a country producing and exporting sugar, molasses, coffee,, tea or hides, it became his duty to issue a proclamation declaring the suspension, as to that country, which Congress had determined should occur. He had no discretion in the premises except. in respect' to. the duration of the suspension so ordered. But that related only to the enforcement of the policy established by Congress. As the suspension was absolutely required',when the President ascertained' the existence of a particular fact, it cannot be said that in ascertaining that fact and in issuing his proclamation, in obedience to the legislative will, he exercised the. function of making laws, legislative power was exercised when Congress declared that the. suspension should take effect upon a named contingency. What the President Was required to.jdo was simply in execution of the act of Congress. • It was not the making of law.' He was .the^mere agent-of the lawmaking department to ascertain and declare the. event upon which its expressed will was. to take effect., It was a part of the law itself as it left the hands-of Congress that the provisions, full' and complete in themselves, permitting the free introduction of sugars, molasses, coffee, tea and'hides, ( from particular countries,- should be suspended, in a given contingency, and that in case of such suspensions certain duties should-be imposed.’.’ Again: “‘The true distinction/ as Judge -Ranney speaking for the- Supreme Court of Ohio has well said, ‘is between the delegation.of power to make the law, *383 which'necessarily involves, a discretion as to what it shall be and conferring authority or discretion as to its execútion, to' be exercise(J sunder and-in pursuance of the law. The first cannot.be done; to the latter no valid objection cari be made.’ Cincinnati, Wilmington &c. Railroad v. Commissioners, 1 Ohio St. 77. In Moers v. Cit y of Reading, 21 Pa. St. 188, 202, the language of the Court was : ‘Half the statutes on our books are. in the-alternative, depending on the discretion of some person or persons to whom is confided the duty of determining whether the proper occasion exists for executing them. But-it cannot be said that- the exercise of such discretion is the making of the law.’ So, in Locke’s Appeal, 72 Pa. St. 491, 498: ‘To assert that a law is less than a law, because it' is riiade to depend oh a future event, or act, is to rob- the legislature of the power to act wisely for the public., welfare whenever a law is passed relating to a state, of affairs' not yet developed, or to things future and impossible To fully know.’ The proper distinction the court said was- this‘The' legislature cannot delegate its power to make a law; but it can make a law to delegate' a power to determine some fact oipstate of things upon which the law makes, or intends to make, its- own action. depénd. To deny this ivould-be to stop the wheels of government. There are many things- upon which wise and useful legislation -must depend which cannot be known to the law-making power, and,must,'therefore, be a subject-of inquiry and determination outside of the halls -of legislation.’ What has been said is equally applicable to the objection that the third section of the act invests the President'with treaty-making power. The court is of the opinion that the third section of the act of October 1, 1890, is not liable to the objection that it .transfers legislative and tfeaty-making power to the President.”. The latest case bearing on the general question is Buttfield v. Stranahan, 192 U. S. 470, 486. That case involved the" constitutionality of the act of Congress of March 2, 1897, 29 Stat. 604, c. 358, relating to the “importations of impure rind unwholesome tea.”' The act provided for the appointment by *384 the Secretary of the Treasury of a board of seven tea experts, who should prepare and submit to him standard samples of that article. One section of' the act 'provided: “That the Secretary of the Treasury, upon the recommendation of the said board, shall fix and establish uniforip standards of purity;' quality, and fitness for consumption of all kinds of teas imported into the United States, and shall procure and deposit in the custom-houses.of the ports of New York, Chicago, San Francisco, and such other ports as he may determine, duplicate: samples pf such standards; -that said Secretary shall procure’ a sufficient number of other duplicate samples of - such stand-, ards to supply the importers and dealers in tea at all ports desiring the same at cost. • All teas; or merchandise described as tea, of inferior purity, quality, and fitness for consumption to such standards shall be deemed, within the prohibition of-the first section hereof.” In that case it was contended that the act was unconstitutional, as making the right to import tea depend upon-the arbitrary action.of the Secretary of the Treasury and a board appointed by him; as excluding from import wholesome, genuine and 'unadulterated tea; and, as discriminating unequally, in the . admission of the different kinds of teas for import, as well as in the right to sell and purchase that"article. The act conferred, it was objected, upon the Secretary and the board the uncontrolled power of fixing standards of purity,, quality and fitness for consumption, and thus to prescribe arbitrarily what teas maybe imported and’ dealt in. ’The question of constitutional law so^raised .was thus disposed of by the.court: “The claim that the statute commits to ’ the arbitrary discretion of' ,the Secretary of the Treasury the determination o'f what teas may be imported; and therefore in effect vests that official with legislative power, is without, merit. We are of opinion ’ that the statute, when properly construed, as said by the Circuit Court of Appeals, but expresses the purpose to exclude'thé lowest grades of tea, whether demonstrably .of inferior purity, or- unfit for consumption, or presumably so because of their inferior quality. *385 This, in effect, was the fixing of a primary standard, and devolved upon the Secretary of the Treasury the mere executive duty to effectuate the legislative policy declared in the statute. The case is within the principle of Field v. Clark, 143 U. S. 649, where it was decided that the third section of the tariff act of October 1, 1890, was not repugnant to the Constitution as conferring legislative and treaty-making power on the President, because it authorized him to suspend the provisions of the act relating to The free introduction of sugar, molasses, coffee, tea and hides. We may say of the legislation in this case, as was said of the legislation consideredjn- Field v. Clark, that it does not, in any real sense, invest' administrative officials with the power1 of legislation. Congress legislated on the subject as far1 as was reasonably practicable, and from the necessities of .the case was compelled to leave to executive officials the duty of bringing about the result pointed out by thé statute. To deny the' power of Congress to delegate such a duty would, in effect, amount but to declaring thaV the plenary power vested in Congress to regulate foreign commerce'could not be efficaciously exerted.” It would seem too clear to admit of serious doubt that the statute under which the Secretary of War proceeded is in entire harmony with the principles announced in former cases. In no substantial, just sense does it confer upon that officer as the head of an Executive Department powers strictly legislative or judicial in their nature, or which must be exclusively exercised by Congress' or by the .courts. It has long been the policy of the Government to remove such unreasonable' obstructions to the free navigation ' of the waterways of the United States as were caused by bridges maintained over them. That such an object was of common interest and within the competency of Congress, under its power to regulate commerce, everyone must admit; for commerce comprehends navigation, and therefore, to free navigation from unreasonable obstructions is a legitímate exertion of that power. Gibbons v. Ogden, 9 Wheat. 1, 189, 190. As appropriate to the object *386 to' be accomplished, as a means to-an end within the power of the National Government, Congress, 'in' execution of a declared policy, committed to the Secretary of War'the duty of ascertaining all the facts essential in any inquiry whether particular bridges, over the waterways of-the United States, were unreasonable obstructions to free navigation. Beyond question, if it had so elected, Congress, in some effective mode 'and without previous investigation through Executive officers, could have determined for itself, primarily, the fact whether the bridge- here in ..question was an unreasonable 'obstruction to navigation, and, If it was found to be;- of that character, could'by direct legislation have-required ' the defendant to make such alterations of its bridge as were, requisite for the protection of navigation and commerce over the' waterway in question. But--investigations by Congress , as to- each particular bridge alleged to constitute an unreasonable obstruction to free navigation and direct legislation covering ea'ch case, separately, would- be impratíticablé in view of the vast and varied interests which require National legislation from time ’to timé. By the statute in question Congress declared in effect that navigation shoúld be freed from unreasonable obstructions arising from bridges'of insufficient height, width of span or other defects. It stopped, however, with this' declaration of a general rule and imposed upon the Secretary of War the duty -of ascertaining what particular cases-, came within the rule prescribed by Congress,, as well as the duty of enforcing the .rule in such cases. In performing,that duty the Secretary of War will only execute the clearly expressed, will of Congress, and will not, in any true sense, exert legislative or judicial power; He could not be said' to exercise strictly legislative or judicial power any more, for instance, than it could be said that Executive officers exercise such power when, upon investigation,, they ascertain whether a •particular applicant for a pension belongs to a class of persons who, under the' general rules prescribed by Congress, are entitled'to pensions. If the, principle-for which the defendant *387 contends received our approval the conclusion could not be avoided that Executive officers,, in all the Departments, in carrying out the -will of Congress, as expressed in statutes enacted by it, have,' from the foundation of the National Government, exercised and are now exdrcising powers, as to mere details, that are strictly legislative or' judicial in their nature. This will ibe apparent upon-an examination of the various" statutes .that confer authority upon Executive Departments in respect, of the enforcement of the laws of the United States. Indeed, it is not too much to say that a denial ■- to Congress of the right, under tlie Constitution, to delegate the power to determine some fact or the state of things upon which'the enforcement of its enactment depends would be “to stop the wheels of government” and bring about con-^ fusion, if not paralysis, in the conduct of the .public business. To this may be added the consideration that Congress, by the act -of .1899, did not invest the Secretary of War with any power in these matters that could reasonably be characterized as arbitrary. He cannot act in reference to any’ bridge.alleged to -be an unreasonable obstruction to free navigation without first giving the parties an opportunity to be héard. He cannot require any1 bridge of that character to be altered,' even f.or the purpose of rendering navigation through or under it' reasonably free, easy and unobstructed, without giving previous notice to the persons or corporations owning or controlling the bridge, specifying the changes recommended-by. the Chief of Engineers, and allowing a reasonable time in which to make them; If, at the end .of ,such time, the required alterations ' have not been made, then the Secretary is ^required to bring'. the matter to the attention of the United States 'District Attorney in order that criminal proceedings may be’ instituted to enforce the act of Congress. In the present case all the provisions of the statute were complied with. The parties concerned were duly notified and were fully heard. Nor is' there any reason to say that the Secretary of War was not entirely justified, if not compelled^ by the evidence in finding *388 that the bridge in question was an' unreasonable obstruction to commerce and navigation as now conducted. ' . 1 We are. of. opinion that the act . in question is> not unconstitutional as conferring upon the Secretary of War powers of such nature that they, could not be delegated to him- by Congress. The next principal contention of1 the Bridge Company is-that the act of 1899 is unconstitutional, in that it -makes no provision, and the United States has not offered, to compensate it' for the sum that will necessarily be expended in order .to make the alterations or changes required by the order of the Secretary of War.' In other words, the defendant insists, that what, the. United States requires to- be done in respect^ of defendant's bridge is a taking of private property for public use, which the Government is forbidden by the Constitution to do without making just compensation to, or without making provision to justly compensate, the owner. Stating the question-'in another way, the contention is, in,effect, that even.if the United States did not expressly assent to the construction of this" bridge as it is, and even if the bridge has become ah unreasonable, obstruction to the free navigation of the waterway in question-, the exertion of the power of the United States .to regulate commerce among the States is subject to the fundamental condition that it cannot require the defendant, whose bridge 'was lawfully constructed, to make -any alterations however necessary to- .secure free 'navigation, without paying or'securing'to it compensation for the'reasonable cost of such alterations,. ,The propositions are combatted by the Government, which contends that^the alterations or changes' required- to secure navigation against an unreasonable obstruction -is not a taking of private property for public use within the meaning of. the Constitution, and that the cost of ,such alterations or changes are to.be deemed incidental only to the exercise of an undoubted function of the United States, when exerting, through Congress, its power to regulate commerce among the States, *389 and therefore navigation upon the waterways on and over which such commerce is conducted. It would seem - clear 'that this issue has likewise been determined by the principles announced in the previous cases of this court. Let us see whether such be the fact. A leading case upon this subject is Gibson v. United States, 166 U. S. 269, 271 et seq. Congress, by the River and Harbor Acts of 1884 and 1886, 23 Stat. 133,147, 24 Stat. 316, 327, authorized and directed the improvement of the Ohio River, and made appropriations - to effect 'that object. Under the authority of the Secretary of War, and the Engineer' Corps of the Army, a dike was constructed in that river for the purpose of concentrating the water-flow in the main channel of the river, near Neville Island. The dike began at a certain point on the .island. Its construction substantially destroyed the landing on and in front of a farm, owned by Mrs. Gibson, on that island — preventing, during most of the year, free egress, and ingress from and to such farm to the .main or navigable channel of the river. At the time of the construction of-the dike that farm was in a high state of cultivation, well improved with a dwelling house, barn and outbuildings. It had a frontage of a thousand feet on the main navigable channel, and the owner had a landing there which was used in the shipping of products from and supplies to her farm, and was the only one from which such products and supplies could be shipped. Before the construction of the dike the farm, by reason of the use to which it was put, was worth six hundred dollars per acre. The obstruction caused by the dike reduced its value to one hundred and fifty-or, two hundred dollars per acre, resulting in damages to the owner in excess of three thousand dollars. Suit was brought against the United States in the Court of Claims to recover such damages'.' That court found as a conclusion of law that the owner was not entitled tó recover. The Chief Justice of this court, delivering its unanimous judgment, said: “All navigable waters are under -the con *390 trol of the United States for the purpose of regulating and improving navigation, and although the title to the shore and submerged soil is in-the'-various-States .and individual owners under them, it is always subject to- the servitude in respect of navigation created in favor of the Federal government by v the Constitution. South Carolina v. Georgia, 93 U. S. 4; Shively v. Bowlby, 152 U. S. 1; Eldridge v. Trezevant v. 160 U. S. 452” After referring to several-adjudged cases-the court proceeded; “The Fifth. Amendment to the Constitution of thfc United-States provides'that, private prop-' erty shall not 'be taken for public use without just compensation.’ Here, however, the damage of. which Mrs. Gibson complained was not the result of tlie taking- of any part of , her property, whether -upland or submerged, or a direct invasion 'thereof, but the' incidental consequence' of the lawful and. proper exercise of a governmental power. The applicable principié is expounded in Transportation Co. v. Chicago, 99 U. S. 635. In that case, plaintiff being an owner of land situated at the intersection of La Salle • street in Chicago, wjth the' Chicago. River, upon which it had valuable dock and warehouse accommodations, 'with a numerous line of steamers accustomed-to land‘at'that dock, was interrupted in his-use thereof by the building.of a tunnel under the'Chicago River -by authority of the state legislature, in accomplishing', which work it'was necessary.-to fear up. La Salle Street, which precluded plaintiff from access to his property for a considerable, timé; also to build a coffer dam i.ri ;the Chicago .River,' which excluded his vessels from.accéss to his'docks; and such an 'injüry was- held to be damnum abs'qué injuria. The, court" said, again speaking 'through Mr. 'Justice Strong: 'But acts done in the -proper- exercise of governmental ■ powers, and not ■directly- encroaching upon ■-private -property,' though ' their consequences may impair its use, are -universally .held'not to be á. taking -within the méanjpg qf -the constitutional pro-..visiion. They .do not entitle the. owner .of such property to •compensation from'.the State or its agents, or give him any *391 right of action. This is supported by an immense weight of authority. . . . Moreover, riparian ownership is subject to the obligation -to suffer the consequences of the improvement of navigation in the exercise of .the dominant right of the Government in that regard. The legislative authority' for these works consisted simply in an- appropriation for their construction, but this was an assertion of a right belonging ' to the Government, to which riparian property was subject, and not- of a right to appropriate private property, not burdened with such servitude, -to public purposes. In short, the damage resulting from the prosecution of this improvement of a navigable highway, for the public good, was not the result of a talcing of appellant’s property, and was merely incidental to the exercise of a servitude to which her property vRad always been subject.” The Gibson case was referred to with approval in Scranton v. Wheeler, 179 U. S. 141, 153, 162. The latter case involved the question whether the owner of land on the St. Mary’s Biver in Michigan was entitled, under the Constitution .of the United States,' to be compensated for the .injury or damage done him, as a riparian owner, by certain work done in that river under the authority of the United States. The controlling question was whether the prohibition in the Constitution of the United States of the taking of private property for public use without just compensation has any application to the case of an owner of land bordering on a public navigable river whose access from his land to navigability is permanently lost by reason of the construction of a. pier resting on submerged lands in front of his upland, and which pier was erected by the United States for the purpose only of improving the navigation of such river. After observing that when that which is done amounts, within the meaning of the Constitution, to a taking of private property for public use, and that Congress may not, in the exercise of its power to regulate commerce, override the provision for just compensation when private property is so taken, the court entered *392 upon a review of some of the-adjudged cases. Among.-other things it said: “All the cases concur in holding that the power of Congress to regulate commerce, and therefore navigation,, is paramount,, and is unrestricted except by the limitations upon its authority by the Constitution.^ Of course, every part of the Constitution is as binding upon Congress as upon the people. • The guarantees prescribed by it for the sécurity of private property must be, respected by all. But whether navigation upon waters over which Congress may exert its authority requires improvement at all, or improvement in a particular way, are matters wholly within its discretion; and the judiciary is without power to control or defeat the will of Congress, so long as that branch of the. Government does not transcend the limits established by the supreme law of .the land. Is- the broad- power .with which Congress is invested burdened with the condition that a riparian owner whose' land borders upon a navigable water mf the . United States shall be compensated for his right of access to navigability whenever such right ceases to be of value in consequence of .the improvement of navigation by means of piers Vesting upon submerged lands away .from the shore line? We think not.” “The primary use,”'the court said, “0f'thé waters' and the lands under them is for 'purposes of navigation, and-the .erection of piers in them to-improve navigation for the ptiblic- is entirely', consistent with, such-use, and infringes no right 'of the • riparian .owner. Whatever ' the" nature of the interest of a riparian owner- in the submerged lands in front of his Upland' bordering .on a- public .náVigable water, his title is not as full and complete as- his title to fast land- which has no direct connection with the navigation of- sueh water. It is - a- qualified title, a bare technical title, not at, his absolute disposal, as- is his upland, but to' -be held at all times subordinate to such use. of the submerged lands and of the waters flowing over' them as may be consistent with of1 demanded, by the public right' of navigation. In Lorman v. Benson, 8 Michigan, 18, 22, the Supreme Court of Michigan,-speaking *393 by Justice Campbell, declared the right of navigation to be one to which all others were subservient. . . . But the contention is that compensation must be made for the loss of the plaintiff’s access from' his upland to navigability incidentally resulting from the occupancy of the submerged lands, even if the construction and maintenance of a pier resting upon them be necessary or valuable in the proper improvement of navigation. We cannot assent to this view". If the riparian owner cannot enjoy access to navigability because of the improvement of navigation by the construction away from the shore line of works in a public navigable river or water, and if such right of access ceases alone for that reason to be of value, there is not, within the meaning of the Constitution, a taking of private property for public use, but only a consequential injury to a right which must be enjoyed, as was said in the Yates case, 'in due-subjection to the rights of the public’ — an injury-resulting incidentally from the exercise of a governmental power for the benefit of the general public, and from which no duty arises to make or secure compensation to the riparian owner. The riparian owner acquired the right of access to navigability subject to the contingency that such right, might become valueless in consequence of the erection under competent authority of structures on the submerged lands in front of his property for the purpose of improving navigation. When erecting the pier in ^question, the Government had no object in view, except, in -the- interest of the public, to improve navigation. It was not designed arbitrarily or capriciously to destroy rights belonging to any riparian owner. What was done was manifestly necessary •to meet the demands of international and interstate com-merpe.” The court further said: “In our opinion, it was not intended that the paramount authority of Congress to improve the navigation of the public navigable waters of the United States sliould be crippled by compelling the Government to make compensation for the injury to a riparian owner’s right of access to navigability that might incidentally résult from *394 an improvemeiit ordered by Congress.- The subject with which -Congress dealt was navigation. That which was sought to -be accomplished was simply to improve navigation on the waters in question so as to meet the wants of the vast commerce' passing and to pass over them. Consequently the agents designated to perform the work ordered .or authorized by Congress-had the right to proceed in all proper ways without taking into áccount the . injury, that might possibly or indirectly result from, such work to-the right of access by riparian owners to navigability. We are of opinion that the court below correctly held that the plaintiff had no, such right of property-in the submerged lands on which' the piel in , question rests as entitles -him, -under the Constitution, to be compensated for any loss of access from his- upland to navigability, resulting from the erection and maintenance of such pier by the'United States in order to improve and which manifestly did ’ improve the navigation of a public navigable water.” In New Orleans Gas Light Co. v. Drainage Comm., 197 U. S. 453, 461, 462, it appeared that, under contract with the City of New- Orleans, and at its. own- .expense, the Gas Light Company had lawfully laid its pipes at certain places in the. public ways and streets of that city. Subsequently, the Drainage Commission of'New Orleans -adopted a pían for the drainage of the .city, which -made it necessary to change the location in' some places of the mains , and pipes theretofore laid by the Gas Light Company. That' company, contended that to-require such changes was-a taking of its property for public Use for. which it. was .entitléd, under the Constitution, to compensation. That view was rejected by this court. We said: “The gas company 'did not acquire any specific location in the streets; it was content with the geñeral right to use. them,, and when it located its pipes itf was at the risk that they might be, at some' future time, disturbed, when the State might require fer a necessary public use that changes in location be made. , •. . .The need of occupation of the *395 soil beneath the streets in cities is constantly increasing, for the supply of water and light and the construction, of systems of sewerage and drainage, and every reason of public policy requires that grants of rights in such sub-surface shall be held subject to such reasonable regulation as the public health and safety may require. .There is nothing in the grant to the gas company,' even if it-could legally be done, undertaking to limit the right of the State to "establish a system of drainage in the streets-. We think whatever right the gas company acquired was subject in so far as the location of its pipes was concerned, to such future regulations as might be required in the interest of the public'health and welfare. These views are amply, sustained by the authorities. National Water Works Co. v. City of Kansas, 28 Fep. Rep. 921, in which the opinion was delivered by Mr. Justice Brewer, then Circuit Judge; Gas Light & Coke Co. v. Columbus, 50 Ohio St. 65; Jamaica Pond Aqueduct Co. v. Brookline, 121 Massachusetts, 5; In re Deering, 93 N. Y. 361; Chicago, Burlington &c. R. R. Co. v. Chicago, 166 U. S. 226, 254. In the. latter case it was held that uncompensated obedience to a regulation enacted for the public safety under the police power of the State was nót taking property without due compensation. In our view, that is all there is to this case. The gas company, by its grant from the city, - acquired no exclusive right to the location of its pipes in the streets, as chosen by it, under a general grant of authority to use the streets. The city made no contract that the gas company should not be disturbed in the location chosen. In the exercise of the police power of the State, for a purpose highly" necessary in the promotion of the public health, it has become necessary to change the location of the pipes of the gas company so as to accommodate them to the hew public work. In complying with this requirement at its own expense none of the property of the gas company has been taken, and" the,injury sustained is damnum absque injuria.” In C., B. & Q. R. R. Co. v. Drainage Com’rs, 200 U. S. 561, *396 582, 593-595, the above cases were cited with approval, and the principles announced in them were applied against a railway company owning a bridge- that had been lawfully constructed by it over a non-navigable' creek running through certain swamp or slough lands which the Drainage Commissioners were required.by statute to drain in order to make them tillable and fit for cultivation. The Commissioners in executing the work of draining found it necessary that the creek over which the, railway bridge was constructed should be deepened and.enlarged, and a greater opening made under the bridge for the passage pf the increased amount of water caused by the deepening 'and enlarging. of the bed of the creek. The railway company was required, at its own cost, to construct such a bridge over the crock as would meet the necessities of the situation as it was or would bo under the drainage plan of the Commissioners’. The .company refused t.o obey the order. The contention of the railway company was that as the bridge was lawfully constructed under -its general-corporate powers, and'ás the de^pth and width of the channel under it were sufficient, at the-time, to carry off the water of the creekas it then and subsequently, flowed, the foundation of the bridge .could pot be removed' and its use of the- bridge disturbed, upless compensation be first made or secured to the company in such amount as would be sufficient t.o meet' the. expense of removing the timbers'-'apd stones from the creek and.of constructing a new bridge of such length and with feuch .opening pnder it as, •the plan of the Commissioners would make • necessary. The company -insisted that, to requird it to meet these expenses out of its. own funds would' be within the meaning of the- Constitution a.taking.of its property for public use without com--pensation, and, therefore, without due process of law. -The court’, after a review of authorities, said: “The. constitutional requirement oí que process or law, wfiiciV'erpbraces compensation for private property taken for public use, applies in every case of the exertion of governmental power. If in the execution of any power, no matter what it is, the Government, *397 Federal or state, finds it necessary to take private property for public use, it must obey the constitutional injunction to make or secure just compensation to the owner. Cherokee Nation v. Southern Kansas Railway, 135 U. S. 641, 659; Sweet v. Rechel, 159 U. S. 380, 399, 402; Monongahela Nav. Co. v. United States, 148 U. S. 312, 336; United States v. Lynah, 188 U. S. 445. If the means employed have no real substantial relation to public objects which government may legally accomplish; if they are arbitrary and unreasonable, beyond the necessities of the case, the judiciary.will disregard mere forms and interfere for the protection of rights injuriously affected by such illegal action. The authority of the courts to interfere in such cases is beyond all doubt. Minnesota v. Barber, 136 U. S. 313, 320. Upon the general subject there is no real conflict among the adjudged cases. Whatever conflict there is arises upon the question whether there has been or will be in the particular case, within the -true meaning of the Constitution, a ‘taking’ of private property for public use. If the injury complained of-is only incidental to the legitimate exercise of governmental powers for the public good, then there is no taking of property for the public use, and a right to com-' pensatiop, on account of such injury, does not attach under-the Constitution. Such is the present- casé.” The opinion 'concluded: “Without further discussion we hold it to be the duty of the railway company, at its own expense, to remove, from the creek -the present bridge, culvert, timbers and stones placed there by it, and also, (unless it abandons'-or surrepders its right to cross the creek at or in .the-vicinity of the present crossing) to erect at its own expense and maintain a new bridge for crossing- that will conform to the regulations established by the Drainage. Commissioners, under the authority of the State; and such a requirement if enforced will not amount to a taking of private property for public use within the meaning of the Constitution, nor to a denial of the equal protection of the laws.” - The latest- adjudication by -this court was in West Chicago *398 Street Railroad v. Chicago, 201 U. S. 506, 524. In that cáse the principal question related to the duty of a street railroad company, which had lawfully constructed a tunnel under the Chicago River, to obey an ordinance of the city, requiring the company, at its own cost and expensé, to lower its tunnel, so as to provide for a certain 'depth under it, which had been ascertained by competent Federal and local authority to be -necessary for the increased demands of navigation. . This court held upon'the adjudged cases that the rights of the company, as the owner of the fee of the land, on eithe'i side of the river or i'n'its bed, were subject to the paramount right of navigation over the waters of the river. It said: “If, then, the right of the railroad company to* have and maintain a tunnel under the- Chicago, river .is subject To the paramount public right of navigation; if its right to maintain a tunnel in the river is a qualified' one, because subject to the (specific condition, in the act- of 1874 that no tunnel should) interrupt navigation; if the present tunnel is an obstruction to navigation, as 'upon this record we must take it to be; and if the city, as representing the'State and public, may rightfully insist that such obstruction shall not longer remain in the way of free navigation; it necessarily follows that the railway company is- under' a duty to comply with the demand made upon it to remove, at its-own expense, the. obstruction which itself has Created' and maintains. Tf the obstruction cannot be, removed except' .by lowering the tunnel to the required depth and (if a tunnel'is to' be maintained) providing one that will hot interrupt navigation; then the cost attendant upon guch work must be met by the company. The city asks' nothing moré than that the-railroad company shall do what is necessary to free navigation from an obstruction for which it is responsible, and'(if .it intends not to abandon its right to maintain a tunnel at or near Van Burén street) th&t it shall itself provide .a new tunnel with the necessary depth of water above it.” Again:'“In the case before us .the public demands nothing to be done by the railroad company except to remove the- obstruction which itself placed and *399 maintains in the river under the condition that navigation should not at any time be thereby interrupted.-, The removal of such obstruction is all that is needed to protect navigation. So that whatever cost attends the removal of the obstruction must b¿ borne by the railroad company. The condition under which the company placed its tunnel in the river being met.by the company, the public has no, further demands upon it. This cannot be deemed a taking of private property for public use or a denial of the equal protection of laws within the meaning .of the Constitution, but is only the result of the lawful' exercise of a governmental power for the common good.' This appears from the authorities cited in Chicago, Burlington & Quincy R. R. Co. v. Drainage Com'rs, supra, just cited. The state court has well said that to -maintain the navigable character of the stream in a lawful way is not, -within the meaning of the law, the taking of private property or any' property right of the owner of the soil under the river, such ownership being subject to the right of free and unobstructed navigation. People v. West Chicago Street R. R. Co., 203 Illinois, 551, 557. What the city asks, and all that it asks, is that the railroad company be required/ in the exercise of its rights and in the use of its property, to respect the public needs as declared by competent authority, upon reasonable grounds, to exist. This is not an arbitrary or- unreasonable demand. It does not, in any legal sense, take or appropriate the company’s property for -the public benefit, but only insists that the company shall not use its property so as to interrupt navigation.” Do the principles announced in the above cases require us to hold, in the present case,-that the making of the alterations of .its bridge specified' in the order of the Secretary of War will, be a taking of the property of the- Bridge Company for public use? We- think not. Unless there be a taking, within thmeaning of- the Constitution,- no obligation arises upon .the United States to make compensation for the cost to be incurred in making such' alterations. , The damage that will, accrue to the Bridge Company,-.as the.result of compliance *400 with the Secretary’s order, must, in such case, be’ deemed incidental to the exercise by the Government of its power to regulate commerce among the States1, which includes, as we have seen, the- power to secure free navigation upon the waterways of the United States against' unreasonable obstructions. There'are no circumstances connected with the original construction of the bridge, or with its maintenance since, which so tie the hands of the Government that it cannot exert its full power to protect the freedom of navigation against obstructions. Although the bridge, when erected under’ the authority of á Pennsylvania chatter, may have been a lawful structure, and although it mays not have been an unreasonable obstruction to commerce and navigation as then carried on, it must be taken, under the cases cited, and upon principle, not only that the company when exerting the power conferred upoñ it by the State, did so with knowledge of the paramount authority of Congress to regulate commerce among the States, but that it erected the bridge subject to the possibility that Congress might, at some future time, when the public interest demanded, exert its power by appropriate legislation to protect navigation against unreasonable obstructions. Even if the bridge, in its original form, was an unreasonable obstruc- ’ tion to navigation, the -mere failure of the United States, at the time, to intervene by its officers or by legislation and prevent its erection, could not create an obligation on the part of the’Government to make compensation, to the company if, at a subsequent time, and for public reasons, Congress should forbid the maintenance of bridges that had become’ unreasonable obstructions to navigation. It is¡ for Congress to determine when it will exert its power to regulate interstate commerce. “Uts mere’’silence or inaction when individuals or corpóratipns, under- the authority of a State, place unreasonable obstructions, in the waterways of the United States, cannot have the éífect to cast upon the Government an obligation not to exert its constitutional power to regulate interstate commerce except ^.subject to the -condition That, compensation be *401 made or secured to the individuals or corporation who may be incidentally affected by the exercise ‘of such power. The principle for which the Bridge Company contends would seriously impair the exercise of the beneficent power of the Government to secure the free and unobstructed navigation of the waterways of the United' States. We cannot give our assent to that' principle. In conformity with the adjudged cases, and in order that" the constitutional.power of Congress may have full operation, we must adjudge that Congress has power to protect pavigation on all waterways of the United. States against unreasonable obstructions, even those creatéd under the sanction of a State, and that an order to so alter a bridge over a waterway of the United States that it .will cease to be an unreasonable-obstruction to navigation will ppt amount to a taking of private property for public use for which coim pensation need be made. Independent of the gfounds upon which we thus place our decision, it is appropriate to observe that the conclusion reached finds Support in the charter of the Bridge Company and in the law of Pennsylvania as declared by its highest court. The charter of the company, as we. have seen, expressly warned the company that its bridge must not obstruct navigation — that is, in legal effect, navigation as it then was, or might be, at any subsequent time. In Dugan v. Bridge Company, 27 Pa. St. 303, 309, 311, we have the case of a bridge company on which was conferred the franchise to erect and maintain a toll-bridge across Monongahela River,- coupled, however, with the condition that such bridge should not .be erected “in such manner as to injure, stop, or interrupt the. navigation of' such river by boats, rafts or other vessels.” The Supreme Court .of Pennsylvania interpreted these words as méaning that “the bridge was to be so built as not to injure,stop or interrupt the navigation, either then or now, whether in its infancy or full growth.” The same general question arose in C., B. & Q. Railway Co. v. Drainage Comm’rs, above cited. This court held that the.adjudged cases “negative the *402 suggestion of the railway company that the adequacy of its bridge and the opening under it for passing the water of the creek at the timé the bridge was constructed determine its obligations to the public at all subsequent periods. In Cooke v. Boston & Lowell R. R., 133 Massachusetts, 185, 188, it appeared that a railroad company had statutory authority to cross a certain highway with its road. The statute provided that if the railroad crossed any highway it should be so constructed as not to impede or obstruct the safe and convenient use of the highway. And one of the contentions of the company was that the statute limited its duty and obligation to provide for the wants of travelers at the time it exercised the privilege granted to it. The. court said: 'The legislature.intended to provide against any. obstruction of the safe and convenient use of the highway for all time; and if, by. the increase of population in the neighborhood, or by an increasing use of the highway, the crossing which at the outset was adequate is no longer so, it is the duty of the railroad corporation to make such alteration as will meet the present needs of the public who have occasion to use the highway.’ In Lake Erie & Western R. R. Co. v. Cluggish, 143 Indiana, 347, the court said (quoting from Lake Erie & Western R. R. Co. v. Smith, 61 Fed. Rep. 885), 'The duty of a railroad to restore a stream or highway which is crossed by the line of its road is a continuing duty; and if, by the increase of population or other causes the crossing becomes inadequate to meet the new and altered conditions of the country, it is the duty of the railroad-to make such alterations as will meet the present needs of the public.’ So, in State of Indiana v. Lake Erie & Western R. R. Co., 83 Fed. Rep. 284, 287, which was the case of an overhead crossing lawfully constructed on one of the streets of a,city, the court said: 'If, by the growth of population or otherwise, the crossing has become inadequate to meet, the present needs of the public, it is the duty of the' railroad company to remedy the defect by restoring the crossing so that it will not unnecessarily impair the usefulness of the highway.’ ” *403 Some stress was laid in'argument upon the fact that com-'-pliance with’the .order of the Secretary of1 War will\compel the Bridge Company to make a very large expenditure in money. But that consideration cannot affect the decision of the questions of constitutional law1 involved. It is one to be addressed^ to the legislative branch of the Government. It is for Congress to determine whether, under the circumstances of a particular case, justice requires, that compensation be made to a-person or corporation incidentally suffering from the exercise by'the-National Government of its constitutional powers. These are all the matters which require notice at our hands; and perceiving rio error" of law on the record, the judgment must be affirmed. It is so ordered. Mr. Justice Brewer and,Mr. Justice Peckham dissent. Mr. Justice Moody did not participate in the consideration or decision of the case.
