Me. Justice White
delivered the opinion of the court.
The steamship company sought the recovery of money paid to the collector of customs of the port of New York which was exacted by that official under an order of the Secretary of Commerce and Labor. The findings of the court, the case by stipulation having been tried without a jury, leave no doubt that the money was paid to the collector under protest, and involuntarily. We say this because the findings establish that thé company was coerced by the certainty that if it did not. pay the collector would refuse a clearance to its steamships plying between New York city and. foreign ports'at periodical and definite sailings, whose failure to depart on time would have caused not only grave public inconvenience from the non-fulfillment of mail contracts, but besides would have entailed upon the. company the most serious pecuniary loss consequent on its failure to carry out many other contracts.
Both the Secretary and the collector were expressly authorized by law, the ope to impose and the other to collect the exactions which were made.. The only question, therefore, is whether the power conferred upon the named officials whs consistent with, the Constitution. The provision under which- the officials acted is §.9 of the act of March 3,1903, entitled, “An Act
to regulate the immigration of aliens into the United States.” c. 1012, 32 Stat. 1213. Light to guide in an analysis of the contentions concerning the asserted repugnancy of the section to the Constitution will- be afforded,by giving at once the merest outline of some of the comprehensive provisions of the act of which it forms a part. •
' The act -excludes from admission into the United States, among other classes,.those afflicted “with loathsome or with dangerous contagious diseases.” § 2. It prohibits the im-. portation of persons for immoral purposes or of persons to perform “labor of service of any kind, skilled or unskilled, by previous solicitation or agreement.” §§ 3 and 4. It imposes the duty on the master of any.vessel having on board alien immigrants to deliver-to the immigrant officer at the port of arrival lists made at the port of embarkation. § 12. These lists are required to b.e verified by the oath of the master of the vessel taken before the immigrant officer at the port of arrival, to the effect that the surgeon of the vessel who sails, therewith' has physically and orally examined each alien, and that’from such examination by the surgeon and from his own investigation the officer of the ship believes that no one of the listed persons is disqualified by law from entering. This list is also required to be verified .by the .affidavit of the surgeon, and in case no surgeon sails .with the ship it is required that .the owner of the vessel employ at the port of embarkation a competent surgeon to make the examination. § § 13 and 14. Upon. the arrival of a vessel in the United States, for the purpose of verifying the lists, immigration officers are authorized to board the vessel, inspect the immigrants and to disembark them for further inspection and medical examination, the disembarkation for such purposes not to be considered as a landing within the United States. The medical examination, the statute provides^ shall be made by medical officers of the United States-Marine-Hospital Service-assigned to such duty, and upon them is imposed the obligation of certifying; “for the information of the immigration officers and the boards of spe
cial inquiry provided for, any and all physical and mental, de-.' fects or diseases observed by said medical officers in any such alien.” In case of controversy concerning the right of an alien to land,'full provision is made for the taking of testimony, and ultimately where a fight to land is challenged, for a determination of the question by boards of inquiry which the statute creates. §§ 16, 17, 24. The cost of maintenance pending investigation or treatment of an alien found to be within the prohibited class or classes is cast upon the vessel and its owners, and the duty of returning at its cost such immigrant to the port from which he-came is also cast upon the ship or its owner. § 19. The performance of the duties which .the act imposes are sanctioned in some cases by the creation of a criminal responsibility, and in others by the imposition of penalties recoverable in civil actions. Thus, among others, it is made á misdemeanor, punishable by fine and imprisonment, for any person to bring into or land, or attempt to do so, any alien not duly admitted by an immigrant inspector or not lawfully entitled to enter. § 6. It is made a misdemeanor, punishable upon' conviction by fine and imprisonment, to land any alien without complying with the requirements for examination by medical officers-as contemplated in the statute. §§17 and 18. And it is'also made a misdemeanor, punishable by fine or imprisonment, to knowingly aid or assist or conspire to procure or permit the entry of an alien into the .United States contrary to the regulations which the statute provides. § 38.' Further, it is made a misdemeanor to refuse to discharge the duty of returning an immigrant and power is given to refuse clearance to the vessel. §• 19. And a penalty, recoverable by civil action, is .authorized for violations of § 4, relating to the importation of aliens under previous contract. ' Section 9, which as we have said is here involved, is as follows;
“That it shall be unlawful for any person, including any transportation company other than railway lines entering the United States from foreign contiguous territory, or the owner, master, agent, or consignee of any vessel; to bring to- the
United States any alien afflicted with a loathsome or with a dangerous contagious disease; and if it shall appear to the satisfaction of the Secretary of the Treasury (Secretary of Commerce and Labor) that any alien so brought to the United States was afflicted with such a disease at the time of foreign embarkation, and that the existence of such disease might have been detected by means of a competent medical examination at such time, such person or transportation company, or the master, agent, owner, or consignee of any such vessel, shall pay to the collector of customs of the customs district in which the port of arrival is located the sum of one hundred dollars for each and every violation of the provisions of this section; and no vessel shall be granted clearance papers while any such fine imposed upon it remains unpaid, nor shall such fine be remitted.”
The express prohibition against bringing into the United States alien immigrants afflicted with “loathsome or dangerous contagious diseases,” which the section contains, is so apparent, and the power to enact the prohibition so obvious, that we dismiss these subjects from further consideration. The exaction which the section authorizes the Secretary of Commerce and Labor to impose, when considered in the light afforded by the context of the statute, is clearly but a power given as a sanction to the duty, which the statute places on the owners of all vessels, to subject all alien emigrants, prior to.bringing them to the United States, to medical examination at the point of' embarkation, so as to.exclude.those afflicted with the prohibited diseases. In other words, the power to impose the exaction which the statute confers on the Secretary is lodged in that officer 'only when it results from the official médical examination at the point of arrival not only that an alien is afflicted with one. of the prohibited diseases, but that the stage of the malady as disclosed by the examination establishes that the alien was suffering with the disease at the time of embarkation, and that such fact would have been, then discovered had -.the. medical examination been then made by the vessel or its
owners, as the statute requires. We think it is also, certain that the power thus lodged in the Secretary of. Commerce and Labor was intended to be exclusive, and that its exertion was authorized as the result of the probative force attributed to' the official medical examination for which the statute provides, and that the power to refuse clearance to vessels was lodged for the express .purpose of causing both the imposition of the exaction and its collection to be acts of administrative .competency, not requiring a resort to judicial power for their enforcement. While we have said that the conclusions just stated are clearly sustained by the text, yet, if ambiguity be conceded, it is dispelled, and the same result is reached; by a consideration of the report of the Senate Committee on Immigration, where the provisions originated, and which we have a right to consider as a guide to its true interpretation.
The Delaware,
161 U. S. 459;
Buttfield
v.
Stranahan,
192 U. S. 470, 495. In that report it was said:
“Notwithstanding the explicit prohibition of the present law, it has been found impossible’to prevent the steamship companies from bringing diseased aliens to our ports. Once on this side, every argument and influence that can be used is resorted to, either to effect the landing of' such aliens or their treatment in the hospital as a preliminary to such landing. Expert medical testimony is secured to attack the diagnosis of the examining surgeon and even to question the contagious nature of the disease’. Pitiable stories are told of the separar tion of parents from young children to induce officers to relax in the discharge of their plain duty. Great" charitable organizations intervene, and even political influence is invoked for the same purpose, the steamship companies themselves, either covertly or openly, displaying a spirit of resistance to the law. If all of these obstacles to the execution of the law fail of their purpose, and the alien afflicted with tuberculosis, favus, or trachoma is sent back, still by the willful or indifferent defiance of this sanitary law the. design sought by its passage is defeated, for hundreds .may possibly have been — indeed,
almost certainly have been — exposed to the disease in the steerage on the way óver, may have been affected by it and landed before it has reached a stage of development sufficiently advanced to be detected by the medical inspector.
“Section 10 of the measure under consideration [which in the final enactment became § 9 of the law] therefore imposes a penalty of $100, to be imposed by the Secretary of the Treasury (now Secretary of Commerce and Labor), for each case brought to an American port, provided in his judgment the disease might have been detected by means of medical examination at the port -of embarkation. This sufficiently guards the transportation lines from an unjust and hasty imposition of the penalty, insures a careful observance of the law, and leaves in their own hands the power to escape even a risk of the fine being imposed, since they can refuse to take on board even the most doubtful case until certified by competent medical authority to be entirely cured.” 57th Con. 1st sess. S. Rept. No. 2119, p. viii; 57th Con. 2d sess. S. Doc. No. 62.
. Resting, as the statute does, upon the authority of Congress over foreign commerce' and its right to control the coming of aliens into the United States, and to regulate that subject in the fullest degree, reserving for future consideration the particular contentions advanced at bar by the plaintiff in error, it may not be doubted that it is not open to discussion that the statute as thus construed was within the power of Congress to enact. In
Buttfield
v.
Stranahan,
192 U. S. 470, considering the subject, it was said (pp. 492, 493):
“Whatever difference of opinion, if any, may have existed or does exist concerning the limitations of'the power resulting from other provisions of the Constitution, so far as interstate commerce is concerned, it is not to be doubted that from the beginning Congress has exercised a plenary power in respect to the exclusion of merchandise brought from foreign countries; not alone directly by the enactment of embargo statutes, but indirectly as a necessary result of provisions contained in tariff legislation. It has also, in other than tariff
legislation, exerted a police, power over foreign commerce by provisions which in and of themselves amounted to the assertion of the right to exclude merchandise-at discretion'
»{í íjc 5^ *|»
“As a resúlt of the complete power of Congress over foreign commerce, it necessarily follows that no individual has a vested right to trade with foreign nations, which is so broad in character as' to limit and restrict the power of Congress to determine what articles of merchandise may be imported into this country and the- terms upon which a right to import may be exercised. This being true, it results that a statute which restrains the introduction of particular goods into the United States from considerations of‘public policy does not violate the due process clause of the Constitution.”
In
Turner
v.
Williams,
194 U. S. 279, in the course of an opinion considering the act here involved, and holding it valid in so far as it provided for the exclusion of anarchists, it was said (p. 289):
“Repeated decisions of this court have determined that Congress has the power to exclude aliens from the United States; to prescribe the terms and conditions-on which they may come in; to establish regulations for sending out of the country such aliens as have entered in violation of law, and to commit-the enforcement of such conditions, and regulations to executive officers; that the deportation. of an alien who is found to be here in violation of law is not a deprivation of liberty without due process of law, and that the provisions of the Constitution securing the right of trial by jury have no application.”
.The whole subject was again reviewed in
United States
v.
Ju Toy,
198 U. S. 253, where, in upholding the validity of the Chinese Exclusion Act, it was observed that the power of Congress to deal with the admission of aliens and to confide the enforcement of such laws to administrative officers was in view of the previous cases no longer open to discussion.
We come to consider the specific grounds which are relied-
upon to remove the case from the control of these general principles.
1. It is insisted that, however complete may be the power of Congress to legislate concerning the exclusion of aliens and to entrust the enforcement of legislation of that character to administrative officers, nevertheless the particular legislation here in question is repugnant to the Constitution because it defines a criminal offense and authorizes a purely administrative official to determine whether the defined crime has been committed, and, if so, to inflict punishment. Conclusive support' for the legal proposition upon which this contention must rest, it is insisted, results from the ruling in
Wong Wing v. United States,
163 U. S. 228, where it was said (p. 237):
“We regard it as settled by our previous decisions that the United States can, as a matter of public policy, by Congressional enactment, forbid aliens or classes of aliens from coming within their borders, and expel aliens or classes of aliens from their territory, and can, in order to make effectual such decree of exclusion or expulsion, devolve the power and duty of identifying and arresting the persons included in such decree, and causing their deportation, upon executive or subordinate officials.
“ But when Congress sees fit to further promote such a policy by subjecting the persons of such aliens to infamous punishment at hard labor, or by confiscating their property, we think such legislation, to be valid, must provide for a judicial trial to establish the guilt of the accused. No limits can be put by the courts upon the'power of Congress to protect, by summary methods, the country from the advent of aliens whose race or habits render them undesirable as citizens, or to expel such if they have already found their way into our land and unlawfully remain therein. But to declare unlawful residence within the country to be an infamous crime, punishable by deprivation of liberty and property, would be to pass out of the sphere of constitutional legislation, unless provision were made that the fact of guilt should first be established by a judicial trial.
It is not consistent with the theory of our Government that the legislature should, after having defined an offense as an infamous crime, find the fact of guilt and adjudge the punishment by one óf its own agents.”
But in so far as the case of Wong Wing held that the trial and punishment' for an infamous offense was not’ an administrative but a judicial function, it is wholly inapposite- to this case, since, on the face of the . section which authorizes the Secretary of Commerce and Labor to impose the' -exaction which is complained of, it is apparent that it does not purport to define and punish an infamous crime, or indeed any criminal offense whatever. Clear as is this conclusion from the text of § 9, when considered alone, it becomes, .if possible, clearer when the section is enlightened by an analysis of the context of the act and by a consideration of the report of the Senate committee to whi,ch we have previously made reference.- We say by an analysis of the context of the act, because, as we have previously stated, its various sections accurately, distinguish between those cases where it was intended that particular violations of the act should be considered as criminal and be punished accordingly, and those where it was contemplated that violations should not constitute crime, but merely entail the infliction of a penalty, enforcible in some cases by purely administrative action and in others by civil suit. We say also by a consideration of the report of the Senate committee, since that report'leaves no doubt that the sole purpose of § 9 was to impose a penalty, based upon the medical examination for which the statute provided, thus tending, by the avoidance of controversy and delay, to secure the efficient performance by the steamship company of the duty to examine in the foreign country, before embarkation, and thereby aid in carrying out the policy of Congress to exclude from the United States aliens afflicted with loathsome or dangerous contagious diseases as defined in the act. The contention that because the exaction which the statute authorizes the Secretary of Commerce and Labor to impose is a penalty,
therefore its enforcement is necessarily governed by the rules controlling in the prosecution of criminal offenses, is clearly without merit, and is not open to discussion.
Hepner
v.
United States,
213 U. S. 103.
2. But it is argued that even though it be conceded that Congress may in some cases impose penalties for the violation of a statutory duty and provide for their enforcement by civil suit instead of by criminal prosecution, as held in
Hepner
v.
United States,
nevertheless that doctrine does not warrant the conclusion that a penalty may be authorized, and its collection committed to an administrative officer without the necessity of resorting to the judicial power. In all cases of penalty or punishment, it is contended, enforcement must depend upon the exertion of judicial power, either by civil or criminal process, since the distinction between judicial and administrative functions cannot be preserved consistently with the recognition of an administrative power to enforce a penalty without resort to judicial authority. But the proposition magnifies the judicial to the detriment of all other departments of the Government, disregards many previous adjudications of this court and ignores practices often manifested and hitherto deemed to be free from any possible constitutional question.
Referring in
Bartlett
v.
Kane,
16 How. 263, to the authority of Congress to confide to administrative officers the enforcement of tariff legislation, it was said (p. 272):
“The interference of the courts with the performance of the ordinary duties of the executive departments of the government would be productive of nothing but mischief; and we are satisfied that such a power was never .intended to be given to them.
Decatur
v.
Paulding,
14 Pet. 499.”
And in the same case, in considering the nature and character of. a penalty of ten per cent which the tariff act of 1842 (5 Stat. 563, chap. 270) authorized administrative officers to impose in cases of undervaluation, it was said (p. 274) :
“An examination of the revenue laws upon the subject of levying additional duties, in consequence of the fact of an un
dervaluation by the importer, shows that they were exacted as discouragements of fraud, and to prevent efforts by importers to escape the legaTrates of duty. In several of the acts this additional duty has been distributed among officers of the customs upon the same conditions as penalties and forfeitures. As between the United States and the importer, . . . it must still be regarded in the light of á penal duty.”

In
Passavant
v.
United States,
148 U. S. 214, the authority of Congress to delegate to administrative officers final and conclusive authority as to the valuation of imported merchandise, accompanied with the power to impose a penalty for undervaluation, was reiterated, and the doctrine of
Bartlett
v.
Kane
was applied. And the same principle was upheld in
Origet
v.
Hedden,
155 U. S. 228.
In accord with this settled judicial construction the legislation of Congress from the% beginning, not only as to tariff but as- to internal revenue, taxation and other subjects, has proceeded on the conception that it was within the competency of Congress, when legislating as to matters exclusively within its control, to impose appropriate obligations and sanction their enforcement by reasonable money penalties, giving to executive officers the power to enforce such penalties without the necessity of invoking the judicial power.
It is insisted that the decisions just stated, and the legislative practices referred to are inapposite, here, because they all relate to subjects peculiarly within the authority of the legislative department of the Government, and which, from the necessity of things, required the concession that administrative officers should have the authority to enforce designated penalties without resort to the courts. But over no conceivable subject is the legislative power of Congress more complete than it is over that With which the act we are now considering deals. If the 'proposition implies that the right of Congress to enact' legislation is to be determined, not by the grant of power made
by the Constitution, -but by considering the particular emergency which has caused Congress to exert a specified power, then the proposition is obviously without foundation. This is apparent, since the contention then would proceed upon the assumption that it is within the competency of judicial authority to control legislative action as to subjects over which there is complete legislative authority, on the theory that there was no necessity calling for the exertion of legislative.power. As the authority of Congress over the right to bring aliens into the United States embraces every conceivable aspect of that subject, it must follow that if Congress has deemed it necessary to impose particular restrictions on the coming in of aliens, and to sanction such prohibitions by penalties enforcible by administrative authority, it follows that the constitutional right of Congress to enact such legislation is the sole measure by which its validity is to be determined by the courts. The suggestion that if this view be applied grave abuses may arise from the mistaken or wrongful exertion by the legislative department of its authority but intimates that if the legislative power be permitted its full sway within its constitutional sphere, harm and wrong will follow, and therefore it behooves the judiciary to apply a corrective by exceeding its own authority.- But as was pointed out in
Cary
v.
Curtis,
3 How. 236, and as- has been often since emphasized by this court
(McCray
v.
United States,
195 U. S. 27), the proposition but mistakenly assumes that the courts can alone be safely intrusted with power, and that hence it is their duty to unlawfully exercise prerogatives which they have no right to exert, upon the assumption that wrong must be done to prevent wrong being accomplished.
3. It is urged that the fines which constituted the exactions were repugnant to the Fifth Amendment, because amounting to a taking of property without due process of law, since, as asserted, the fines were imposed, in some cases, without any previous notice, and in all cases without any adequate notice • or opportunity to defend. Stated in the briefest form, the
findings below show that on the arrival of a vessel, if the examining medical officers discovered that an immigrant was afflicted with one of the prohibited diseases, the owner of the vessel was notified of the fact, and, indeed, that the steamship company had at the place where the examination was made what is known as a landing agent, whose business it was to keep informed as to the result of medical examinations, and to know when an immigrant was detained by the medical officers because afflicted with a prohibited disease. The findings also established that where a fine was imposed under § 9 by the Secretary of Commerce and Labor it was only done after the transmission to that official of the certificate of the examining medical officer that a particular alien immigrant had been' found to be afflicted with one of the prohibited diseases, and that the state of the disease established in the opinion of the medical officer that it existed at the time of embarkation, and could then have been detected by a competent medical examination. Prior to a certain date the action of the Secretary of Commerce and Labor imposing a fine was notified to the steamship company and demand of payment was practically at once made. After a certain date, by what is known as circular No. 58, the same process was followed as to the imposition of the fine, but a period of time — fourteen days — was allowed to intervene between the notice given of the imposition of the fine and its final and compulsory exaction. As to the action of the Secretary of Commerce and Labor before the promulgation of circular No. 58, the court below found that no adequate opportunity was afforded the vessel or its owner to be heard, and, as to the notice given after the promulgation of- circular No. 58, it was found that -the fourteen days allowed by that circular, and the practice under it, “did not afford the plaintiff a reasonable opportunity to obtain evidence from the port of embarkation and to be heard upon the question whether a fine should be imposed.” .Much contention is made in argument concerning these findings, it being insisted that there is conflict between them, and different views are taken as to
which of the findings should, under the circumstances of the case, be treated as dominant. But into that controversy we do not think it necessary to enter, since, as previously pointed out, it is evident that the statute unambiguously excludes the conception that the steamship company was entitled to be heard, in the sense of raising an issue and tendering, evidence concerning the condition of .the alien immigrant upon arrival at the point of disembarkation, as the plain purpose of the statute was to exclusively commit that subject to the medical officers for which the statute provided. We shall, therefore, test the soundness, of the proposition we are considering upon that assumption.
In view of the absolute power of Congress oyer the right'to bring aliens into the United States we think it may not be doubted that the act would be beyond all question constitutional if it forbade the introduction of aliens afflicted with contagious diseases, and, as a condition to the right to bring in aliens, imposed upon every vessel .bringing them in, as a .condition of the right to do so, a penalty for every alien brought to the. United States afflicted with the prohibited disease, wholly without reference'to when and where the disease originated. „ It must then follow that the' provision contained in the statute is of course valid, since it only subjects the vessel to the exaction when, as the result of the medical examination.for which the statute provides, it appears that the alien immigrant afflicted with-the prohibited malady is in such a stage of the disease that it must in the opinion of the medical officer have existed and been susceptible of discovery at the point of embarkation. Indeed,-it is not denied that there was full power in Congress to provide for the examination of the alien, by medical officers and to attach conclusive effect to the result of that examination for the purposes of exclusion or deportation. But it is said the power to do so- does not include the right to make the medical examination conclusive for the purpose of imposing.a penalty upon the vessel for the negligent bringing in of an alien. We think the argument-rests •
upon a distinction without a difference. It disregards the purpose which, as we have already pointed out, Congress had in view in the enactment of the provision, that is, the guarding against the danger to arise from the wrongful taking on board of an alien afflicted with a contagious malady, not only to other immigrant passengers, but ultimately it might be to the entire people of the United States, a danger arising from the possible admission of aliens who might contract the contagion during the voyage and yet be entitled to admission because apparently not afflicted with the prohibited disease, owing to the fact that the time had not elapsed for the manifestation of its presence. In effect, all the contentions pressed in argument concerning the repugnancy of the statute to the due process clause really disregarded the complete and absolute power of Congress over the subject with which the statute deals. They mistakenly assume that mere form and not substance may be made by the courts the conclusive test as to the constitutional ■power, of Congress to enact a statute. These conclusions are apparent, we think, since the plenary power of Congress as to the admission of aliens leaves no room for doubt as to its authority to impose the penalty, and its complete administrative control over the granting or refusal of a clearance also leaves no doubt of the right to endow administrative officers with discretion to refuse to perform the administrative act of granting a clearance as a means of enforcing the penalty which there was lawful authority to impose.
There are many other propositions urged in argument which we do not deem it necessary to specifically notice, as in effect they are all disposed of by the considerations which we have stated.
We have not considered the questions which would arise for decision if the case presented an attempt to endow administrative officers with the power to enforce a lawful exaction by methods which were not within the competency of administrative duties, because they .required the exercise of judicial authority.
Affirmed.
