41 U.S. 539
Prigg v. Pennsylvania
This is a writ of error to the supreme court of Pennsylvania, brought under the 25th section of the judiciary act of 1789, ch. 20, for the purpose of revising the judgment of that court, in a case involving the construction of the constitution and laws of the United States. The facts are briefly these:
The plaintiff in error was indicted in the court of oyer and terminer for York county, for having, with force and violence, taken and carried away from that county, to the state of Maryland, a certain negro woman, named Margaret Morgan, with a design and intention of selling and disposing of, and keeping her, as a slave or servant for life, contrary to a statute of Pennsylvania, passed on the 26th of March 1826. That statute, in the first section, in substance, provides, that if any person or persons shall, from and after the passing of the act, by force and violence, take and carry away, or cause to be taken and carried away, and shall, by fraud or false pretence, seduce, or cause to be seduced, or shall attempt to take, carry away or seduce, any negro or mulatto, from any part of that commonwealth, with a design and intention of selling and disposing of, or causing to be sold, or of keeping and detaining, or of causing to be kept and detained, such negro or mulatto, as a slave or servant for life, or for any term whatsoever; every such person or persons, his or their aiders or abettors, shall, on conviction thereof, be deemed guilty of felony, and shall forfeit and pay a sum not less than five hundred, nor more than one thousand dollars; and moreover, shall be sentenced to undergo servitude for any term or terms of years, not less than seven years nor exceeding twenty-one years; and shall be confined and kept to hard labor, &c. There are many other provisions in the statute, which is recited at large in the record, but to which it is in our view unnecessary to advert upon the present occasion.
The plaintiff in error pleaded not guilty to the indictment; and at the trial, the jury found a special verdict, which, in substance, states, that the negro woman, Margaret Morgan, was a slave for life, and held to labor and service under and according to the laws of Maryland, to a certain Margaret Ashmore, a citizen of Maryland; that the slave escaped and fled from Maryland, into Pennsylvania, in 1832; that the plaintiff in error, being legally constituted the agent and attorney of the said Margaret Ashmore, in 1837, caused the said negro woman to be taken and apprehended as a fugitive from labor, by a state constable, under a warrant from a Pennsylvania magistrate; that the said negro woman was thereupon brought before the said magistrate, who refused to take further cognisance of the case; and thereupon, the plaintiff in error did remove, take and carry away the said negro woman and her children, out of Pennsylvania, into Maryland, and did deliver the said negro woman and her children into the custody and possession of the said Margaret Ashmore. The special verdict further finds, that one of the children was born in Pennsylvania, more than a year after the said negro woman had fled and escaped from Maryland. Upon this special verdict, the court of oyer and terminer of York county adjudged that the plaintiff in error was guilty of the offence charged in the indictment. A writ of error was brought from that judgment to the supreme court of Pennsylvania, where the judgment was, pro forma, affirmed. From this latter judgment, the present writ of error has been brought to this court.
Before proceeding to discuss the very important and interesting questions involved in this record, it is fit to say, that the cause has been conduced in the court below, and has been brought here by the co-operation and sanction, both of the state of Maryland, and the state of Pennsylvania, in the most friendly and courteous spirit, with a view to have those questions finally disposed of by the adjudication of this court; so that the agitations on this subject, in both states, which have had a tendency to interrupt the harmony between them, may subside, and the conflict of opinion be put at rest. It should also be added, that the statute of Pennsylvania of 1826, was (as has been suggested at the bar) passed with a view of meeting the supposed wishes of Maryland on the subject of fugitive slaves; and that, although it has failed to produce the good effects intended in its practical construction, the result was unforeseen and undesigned.
The question arising in the case, as to the constitutionality of the statute of Pennsylvania, has been most elaborately argued at the bar. The counsel for the plaintiff in error have contended, that the statute of Pennsylvania is unconstitutional; first, because congress has the exclusive power of legislation upon the subject-matter, under the constitution of the United States, and under the act of the 12th of February 1793, ch. 51, which was passed in pursuance thereof; secondly, that if this power is not exclusive in congress, still the concurrent power of the state legislatures is suspended by the actual exercise of the power of congress; and thirdly, that if not suspended, still the statute of Pennsylvania, in all its provisions applicable to this case, is in direct collision with the act of congress, and therefore, is unconstitutional and void. The counsel for Pennsylvania maintain the negative of all those points.
Few questions which have ever come before this court involve more delicate and important considerations; and few upon which the public at large may be presumed to feel a more profound and pervading interest. We have accordingly given them our most deliberate examination; and it has become my duty to state the result to which we have arrived, and the reasoning by which it is supported.
Before, however, we proceed to the points more immediately before us, it may be well, in order to clear the case of difficulty, to say, that in the exposition of this part of the constitution, we shall limit ourselves to those considerations which appropriately and exclusively belong to it, without laying down any rules of interpretation of a more general nature. It will, indeed, probably, be found, when we look to the character of the constitution itself, the objects which it seeks to attain, the powers which it confers, the duties which it enjoins, and the rights which it secures, as well as the known historical fact, that many of its provisions were matters of compromise of opposing interests and opinions, that no uniform rule of interpretation can be applied to it, which may not allow, even if it does not positively demand, many modifications, in its actual application to particular clauses. And, perhaps, the safest rule of interpretation, after all, will be found to be to look to the nature and objects of the particular powers, duties and rights, with all the lights and aids of contemporary history; and to give to the words of each just such operation and force, consistent with their legitimate meaning, as may fairly secure and attain the ends proposed.
There are two clauses in the constitution upon the subject of fugitives, which stands in juxtaposition with each other, and have been thought mutually to illustrate each other. They are both contained in the second section of the fourth article, and are in the following words: 'A person charged in any state with treason, felony or other crime, who shall flee from justice, and be found in another state, shall, on demand of the executive authority of the state from which he fled, be delivered up, to be removed to the state having jurisdiction of the crime.' 'No person held to service or labor in one state, under the laws thereof, escaping into another, shall, in consequence of any law or regulation therein, be discharged from such service or labor; but shall be delivered up, on claim of the party to whom such service or labor may be due.'
The last clause is that, the true interpretation whereof is directly in judgment before us. Historically, it is well known, that the object of this clause was to secure to the citizens of the slave-holding states the complete right and title of ownership in their slaves, as property, in every state in the Union into which they might escape from the state where they were held in servitude. The full recognition of this right and title was indispensable to the security of this species of property in all the slave-holding states; and, indeed, was so vital to the preservation of their domestic interests and institutions, that it cannot be doubted, that it constituted a fundamental article, without the adoption of which the Union could not have been formed. Its true design was, to guard against the doctrines and principles prevalent in the non-slave-holding states, by preventing them from intermeddling with, or obstructing, or abolishing the rights of the owners of slaves.
By the general law of nations, no nation is bound to recognise the state of slavery, as to foreign slaves found within its territorial dominions, when it is in opposition to its own policy and institutions, in favor of the subjects of other nations where slavery is recognised. If it does it, it is as a matter of comity, and not as a matter of international right. The state of slavery is deemed to be a mere municipal regulation, founded upon and limited to the range of the territorial laws. This was fully recognised in Somerset's Case, Lofft 1; s. c. 11 State Trials, by Harg. 340; s. c. 20 How. State Trial 79; which decided before the American revolution. It is manifest, from this consideration, that if the constitution had not contained this clause, every non-slave-holding state in the Union would have been at liberty to have been at liberty to have declared free all runaway slaves coming within its limits, and to have given them entire immunity and protection against the claims of their masters; a course which would have created the most bitter animosities, and engendered perpetual strife between the different states. The clause was, therefore, of the last importance to the safety and security of the southern states, and could not have been surrendered by them, without endagering their whole property in slaves. The clause was accordingly adopted into the constitution, by the unanimous consent of the framers of it; a proof at once of its intrinsic and practical necessity.
How, then, are we to interpret the language of the clause? The true answer is, in such a manner as, consistently with the words, shall fully and completely effectuate the whole objects of it. If, by one mode of interpretation, the right must become shadowy and unsubstantial, and without any remedial power adequate to the end, and by another mode, it will attain its just end and secure its manifest purpose, it would seem, upon principles of reasoning, absolutely irresistible, that the latter ought to prevail. No court of justice can be authorized so to construe any clause of the constitution as to defeat its obvious ends, when another construction, equally accordant with the words and sense thereof, will enforce and protect them.
The clause manifestly contemplates the existence of a positive, unqualified right on the part of the owner of the slave, which no state law or regulation can in any way qualify, regulate, control or restrain. The slave is not to be discharged from service or labor, in consequence of any state law or regulation. Now, certainly, without indulging in any nicety of criticism upon words, it may fairly and reasonably be said, that any state law or state regulation, which interrupts, limits, delays or postpones the right of the owner to the immediate possession of the slave, and the immediate command of his service and labor, operates, pro tanto, a discharge of the slave therefrom. The question can never be, how much the slave is discharged from; but whether he is discharged from any, by the natural or necessary operation of state laws or state regulations. The question is not one of quantity or degree, but of withholding or controlling the incidents of a positive and absolute right.
We have said, that the clause contains a positive and unqualified recognition of the right of the owner in the slave, unaffected by any state law or legislation whatsoever, because there is no qualification or restriction of it to be found therein; and we have no right to insert any, which is not expressed, and cannot be fairly implied. Especially, are we estopped from so doing, when the clause puts the right to the service or labor upon the same ground, and to the same extent, in every other state as in the state from which the slave escaped, and in which he was held to the service or labor. If this be so, then all the incidents to that right attach also. The owner must, therefore, have the right to seize and repossess the slave, which the local laws of his own state confer upon him, as property; and we all know that this right of seizure and recaption is universally acknowledged in all the slave-holding states. Indeed, this is no more than a mere affirmance of the principles of the common law applicable to this very subject. Mr. Justice Blackstone (3 Bl. Com. 4) lays it down as unquestionable doctrine. 'Recaption or reprisal (says he) is another species of remedy by the mere act of the party injured. This happens, when any one hath deprived another of his property in goods or chattels personal, or wrongfully detains one's wife, child or servant; in which case, the owner of the goods, and the husband, parent or master, may lawfully claim and retake them, wherever he happens to find them, so it be not in a riotous manner, or attended with a breach of the peace.' Upon this ground, we have not the slightest hesitation in holding, that under and in virtue of the constitution, the owner of a slave is clothed with entire authority, in every state in the Union, to seize and recapture his slave, whenever he can do it, without any breach of the peace or any illegal violence. In this sense, and to this extent, this clause of the constitution may properly be said to execute itself, and to require no aid from legislation, state or national.
But the clause of the constitution does not stop here; nor, indeed, consistently with its professed objects, could it do so. Many cases must arise, in which, if the remedy of the owner were confined to the mere right of seizure and recaption, he would be utterly without any adequate redress. He may not be able to lay his hands upon the slave. He may not be able to enforce his rights against persons, who either secrete or conceal, or withhold the slave. He may be restricted by local legislation, as to the mode of proofs of his ownership; as to the courts in which he shall sue, and as to the actions which he may bring; or the process be may use to compel the delivery of the slave. Nay! the local legislation may be utterly inadequate to furnish the appropriate redress, by authorizing no process in rem, or no specific mode of repossessing the slave, leaving the owner, at best, not that right which the constitution designed to secure, a specific delivery and repossession of the slave, but a mere remedy in damages; and that, perhaps, against persons utterly insolvent or worthless. The state legislation may be entirely silent on the whole subject, and its ordinary remedial process framed with different views and objects; and this may be innocently as well as designedly done, since every state is perfectly competent, and has the exclusive right, to prescribe the remedies in its own judicial tribunals, to limit the time as well as the mode of redress, and to deny jurisdiction over cases, which its own policy and its own institutions either prohibit or discountenance. If, therefore, the clause of the constitution had stopped at the mere recognition of the right, without providing or contemplating any means by which it might be established and enforced, in cases where it did not execute itself, it is plain, that it would have been, in a great variety of cases, a delusive and empty annunciation. If it did not contemplate any action, either through state or national legislation, as auxiliaries to its more perfect enforcement in the form of remedy, or of protection, then, as there would be no duty on either to aid the right, it would be left to the mere comity of the states, to act as they should please, and would depend for its security upon the changing course of public opinion, the mutations of public policy, and the general adaptations of remedies for purposes strictly according to the lex fori.
And this leads us to the consideration of the other part of the clause, which implies at once a guarantee and duty. It says, 'but he (the slave) shall be delivered up, on claim of the party to whom such service or labor may be due.' Now, we think it exceedingly difficult, if not impracticable, to read this language, and not to feel, that it contemplated some further remedial redress than that which might be administered at the hands of the owner himself. A claim is to be made! What is a claim? It is, in a just jurisdical sense, a demand of some matter, as of right, made by one person upon another, to do or to forbear to do some act or thing as a matter of duty. A more limited, but at the same time, an equally expressive, definition was given by Lord DYER, as cited in Stowel v. Zouch, 1 Plowd. 359; and it is equally applicable to the present case: that 'a claim is a challenge by a man of the propriety or ownership of a thing, which he has not in possession, but which is wrongfully detained from him.' The slave is to be delivered up on the claim. By whom to be delivered up? In what mode to be delivered up? How, if a refusal takes place, is the right of delivery to be enforced? Upon what proofs? What shall be the evidence of a rightful recaption or delivery? When and under what circumstances shall the possession of the owner, after it is obtained, be conclusive of his right, so as to preclude any further inquiry or examination into it by local tribunals or otherwise, while the slave, in possession of the owner, is in transitu to the state from which he fled? These and many other questions will readily occur upon the slightest attention to the clause; and it is obvious, that they can receive but one satisfactory answer. They require the aid of legislation, to protect the right, to enforce the delivery, and to secure the subsequent possession of the slave. If, indeed, the constitution guaranties the right, and if it requires the delivery upon the claim of the owner (as cannot well be doubted), the natural inference certainly is, that the national government is clothed with the appropriate authority and functions to enforce it. The fundamental principle, applicable to all cases of this sort, would seem to be, that where the end is required, the means are given; and where the duty is enjoined, the ability to perform it is contemplated to exist, on the part of the functionaries to whom it is intrusted. The clause is found in the national constitution, and not in that of any state. It does not point out any state functionaries, or any state action, to carry its provisions into effect. The states cannot, therefore, be compelled to enforce them; and it might well be deemed an unconstitutional exercise of the power of interpretation, to insist, that the states are bound to provide means to carry into effect the duties of the national government, nowhere delegated or intrusted to them by the constitution. On the contrary, the natural, if not the necessary, conclusion is, that the national government, in the absence of all positive provisions to the contrary, is bound, through its own proper departments, legislative, judicial or executive, as the case may require, to carry into effect all the rights and duties imposed upon it by the constitution. The remark of Mr. Madison, in the Federalist (No. 43), would seem in such cases to apply with peculiar force. 'A right (says he) implies a remedy; and where else would the remedy be deposited, than where it is deposited by the constitution?' meaning, as the context shows, in the government of the United States.
It is plain, then, that where a claim is made by the owner, out of possession, for the delivery of a slave, it must be made, if at all, against some other person; and inasmuch as the right is a right of property, capable of being recognised and asserted by proceedings before a court of justice, between parties adverse to each other, it constitutes, in the strictest sense, a controversy between the parties, and a case 'arising under the constitution' of the United States, within the express delegation of judicial power given by that instrument. Congress, then, may call that power into activity, for the very purpose of giving effect to that right; and if so, then it may prescribe the mode and extent in which it shall be applied, and how, and under what circumstances, the proceedings shall afford a complete protection and guarantee to the right.
Congress has taken this very view of the power and duty of the national government. As early as the year 1791, the attention of congress was drawn to it (as we shall hereafter more fully see), in consequence of some practical difficulties arising under the other clause, respecting fugitives from justice escaping into other states. The result of their deliberations was the passage of the act of the 12th of February 1793, ch. 51, which, after having, in the first and second sections, provided by the case of fugitives from justice, by a demand to be made of the delivery, through the executive authority of the state where they are found, proceeds, in the third section, to provide, that when a person held to labor or service in any of the United States, shall escape into any other of the states or territories, the person to whom such labor or service may be due, his agent or attorney, is hereby empowered to seize or arrest such fugitive from labor, and take him or her before any judge of the circuit or district courts of the United States, residing or being within the state, or before any magistrate of a county, city or town corporate, wherein such seizure or arrest shall be made; and upon proof, to the satisfaction of such judge or magistrate, either by oral evidence or affidavit, &c., that the person so seized or arrested, deth, under the laws of the state or territory from which he or she fled, owe service or labor to the person claiming him or her, it shall be the duty of such judge or magistrate, to give a certificate thereof to such claimant, his agent or attorney, which shall be sufficient warrant for removing the said fugitive from labor, to the state or territory from which he or she fled. The fourth section provides a penalty against any person, who shall knowingly and willingly obstruct or hinder such claimant, his agent or attorney, in so seizing or arresting such fugitive from labor, or rescue such fugitive from the claimant, or his agent or attorney, when so arrested, or who shall harbor or conceal such fugitive, after notice that he is such; and it also saves to the person claiming such labor or service, his right of action for or on account of such injuries.
In a general sense, this act may be truly said to cover the whole ground of the constitution, both as to fugitives from justice, and fugitive slaves; that is, it covers both the subjects, in its enactments; not because it exhausts the remedies which may be applied by congress to enforce the rights, if the provisions of the act shall in practice be found not to attain the object of the constitution; but because it points out fully all the modes of attaining those objects, which congress, in their discretion, have as yet deemed expedient or proper to meet the exigencies of the constitution. If this be so, then it would seem, upon just principles of construction, that the legislation of congress, if constitutional, must supersede all state legislation upon the same subject; and by necessary implication prohibit it. For, if congress have a constitutional power to regulate a particular subject, and they do actually regulate it in a given manner, and in a certain form, it cannot be, that the state legislatures have a right to interfere, and as it were, by way of compliment to the legislation of congress, to prescribe additional regulations, and what they may deem auxiliary provisions for the same purpose. In such a case, the legislation of congress, in what it does prescribe, manifestly indicates, that it does not intend that there shall be any further legislation to act upon the subject-matter. Its silence as to what it does not do, is as expressive of what its intention is, as the direct provisions made by it. This doctrine was fully recognised by this court, in the case of Houston v. Moore, 5 Wheat. 1, 21-2; where it was expressly held, that where congress have exercised a power over a particular subject given them by the constitution, it is not competent for state legislation to add to the provisions of congress upon that subject; for that the will of congress upon the whole subject is as clearly established by what it has not declared, as by what it has expressed.
But it has been argued, that the act of congress is unconstitutional, because it does not fall within the scope of any of the enumerated powers of legislation confided to that body; and therefore, it is void. Stripped of its artificial and technical structure, the argument comes to this, that although rights are exclusively secured by, or duties are exclusively imposed upon, the national government, yet, unless the power to enforce these rights or to execute these duties, can be found among the express powers of legislation enumerated in the constitution, they remain without any means of giving them effect by any act of congress; and they must operate solely proprio vigore, however defective may be their operation; nay! even although, in a practical sense, they may become a nullity, from the want of a proper remedy to enforce them, or to provide against their violation. If this be the true interpretation of the constitution, it must, in a great measure, fail to attain many of its avowed and positive objects, as a security of rights, and a recognition of duties. Such a limited construction of the constitution has never yet been adopted as correct, either in theory or practice. No one has ever supposed, that congress could, constitutionally, by its legislation, exercise powers, or enact laws, beyond the powers delegated to it by the constitution. But it has, on various occasions, exercised powers which were necessary and proper as means to carry into effect rights expressly given, and duties expressly enjoined thereby. The end being required, it has been deemed a just and necessary implication, that the means to accomplish it are given also; or, in other words, that the power flows as a necessary means to accomplish the end.
Thus, for example, although the constitution has declared, that representatives shall be apportioned among the states according to their respective federal numbers; and for this purpose, it has expressly authorized congress, by law, to provide for an enumeration of the population every ten years; yet the power to apportion representatives, after this enumeration is made, is nowhere found among the express powers given to congress, but it has always been acted upon, as irresistibly flowing from the duty positively enjoined by the constitution. Treaties made between the United States and foreign powers, often contain special provisions, which do not execute themselves, but require the interposition of congress to carry them into effect, and congress has constantly, in such cases, legislated on the subject; yet, although the power is given to the executive, with the consent of the senate, to make treaties, the power is nowhere in positive terms conferred upon congress to make laws to carry the stipulations of treaties into effect; it has been supposed to result from the duty of the national government to fulfil all the obligations of treaties. The senators and representatives in congress are, in all cases, except treason, felony and breach of the peace, exempted from arrest, during their attendance at the sessions thereof, and in going to and returning from the same. May not congress enforce this right, by authorizing a writ of habeas corpus, to free them from an illegal arrest, in violation of this clause of the constitution? If it may not, then the specific remedy to enforce it must exclusively depend upon the local legislation of the states; and may be granted or refused, according to their own varying policy or pleasure. The constitution also declares, that the privilege of the writ of habeas corpus shall not be suspended, unless, when in cases of rebellion or invasion, the public safety may require it. No express power is given to congress to secure this invaluable right in the non-enumerated cases, or to suspend the writ in cases of rebellion or invasion. And yet it would be difficult to say, since this great writ of liberty is usually provided for by the ordinary functions of legislation, and can be effectually provided for only in this way, that it ought not to be deemed, by necessary implication, within the scope of the legislative power of congress. These cases are put merely by way of illustration, to show, that the rule of interpretation, insisted upon at the argument, is quite too narrow to provide for the ordinary exigencies of the national government, in cases where rights are intended to be absolutely secured, and duties are positively enjoined by the constitution.
The very act of 1793, now under consideration, affords the most conclusive proof, that congress has acted upon a very different rule of interpretation, and has supposed, that the right as well as the duty of legislation on the subject of fugitives from justice, and fugitive slaves, was within the scope of the constitutional authority conferred on the national legislature. In respect to fugitives from justice, the constitution, although it expressly provides, that the demand shall be made by the executive authority of the state from which the fugitive has fled, is silent as to the party upon whom the demand is to be made, and as to the mode in which it shall be made. This very silence occasioned embarrassments in enforcing the right and duty, at an early period after the adoption of the constitution; and produced a hesitation on the part of the executive authority of Virginia to deliver up a fugitive from justice, upon the demand of the executive of Pennsylvania, in the year 1791; and as we historically know from the message of President Washington, and the public documents of that period, it was the immediate cause of the passing of the act of 1793, which designated the person (the state executive) upon whom the demand should be made, and the mode and proofs upon and in which it should be made. From that time down to the present hour, not a doubt has been breathed upon the constitutionality of this part of the act; and every executive in the Union has constantly acted upon and admitted its validity. Yet the right and the duty are dependent, as to their mode of execution, solely on the act of congress; and but for that, they would remain a nominal right and passive duty, the execution of which being intrusted to and required of no one in particular, all persons might be at liberty to disregard it. This very acquiescence, under such circumstances, of the highest state functionaries, is a most decisive proof of the universality of the opinion, that the act is founded in a just construction of the constitution, independent of the vast influence, which it ought to have as a contemporaneous exposition of the provisions, by those who were its immediate framers, or intimately connected with its adoption.
The same uniformity of acquiescence in the validity of the act of 1793, upon the other part of the subject-matter, that of fugitive slaves, has prevalied throughout the whole Union, until a comparatively recent period. Nay! being from its nature and character more readily susceptible of being brought into controversy in courts of justice, than the former, and of enlisting in opposition to it, the feelings, and it may be, the prejudices, of some portions of the non-slaveholding states, it has naturally been brought under adjudication in several states in the Union, and particularly in Massachusetts, New York and Pennsylvania; and on all these occasions its validity has been affirmed. The cases cited at the bar, of Wright v. Deacon, 5 Serg. & Rawle 62; Glen v. Hodges, 9 Johns. 67; Jack v. Martin, 12 Wend. 311; s. c. 12 Ibid. 507; and Commonwealth v. Griffin, 2 Pick. 11, are directly in point. So far as the judges of the courts of the United States have been called upon to enforce it, and to grant the certificate required by it, it is believed, that it has been uniformly recognised as a binding and valid law, and as imposing a constitutional duty. Under such circumstances, if the question were one of doubtful construction, such long acquiescence in it, such contemporaneous expositions of it, and such extensive and uniform recognition of its validity, would, in our judgment, entitle the question to be considered at rest; unless, indeed, the interpretation of the constitution is to be delivered over to interminable doubt throughout the whole progress of legislation and of national operations. Congress, the executive, and the judiciary, have, upon various occasions, acted upon this as a sound and reasonable doctrine. Especially did this court, in the cases of Stuart v. Laird, 1 Cranch 299, and Martin v. Hunter, 1 Wheat. 304, and in Cohens v. Commonwealth of Virginia, 6 Ibid. 264, rely upon contemporaneous expositions of the constitution, and long acquiescence in it, with great confidence, in the discussion of questions of a highly interesting and important nature.
But we do not wish to rest our present opinion upon the ground either of contemporaneous exposition, or long acquiescence, or even practical action; neither do we mean to admit the question to be of a doubtful nature, and therefore, as properly calling for the aid of such considerations. On the contrary, our judgment would be the same, if the question were entirely new, and the act of congress were of recent enactment. We hold the act to be clearly constitutional, in all its leading provisions, and, indeed, with the exception of that part which confers authority upon state magistrates, to be free from reasonable doubt and difficulty, upon the grounds already stated. As to the authority so conferred upon state magistrates, while a difference of opinion has existed, and may exist still, on the point, in different states, whether state magistrates are bound to act under it, none is entertained by this court, that state magistrates may, if they choose, exercise that authority, unless prohibited by state legislation.
The remaining question is, whether the power of legislation upon this subject is exclusive in the national government, or concurrent in the states, until it is exercised by congress. In our opinion, it is exclusive; and we shall now proceed briefly to state our reasons for that opinion. The doctrine stated by this court, in Sturges v. Crowninshield, 4 Wheat. 122, 193, contains the true, although not the sole, rule or consideration, which is applicable to this particular subject. 'Wherever,' said Mr. Chief Justice MARSHALL, in delivering the opinion of the court, 'the terms in which a power is granted to congress, or the nature of the power, require, that it should be exercised exclusively by congress, the subject is as completely taken from the state legislatures, as if they had been forbidden to act.' The nature of the power, and the true objects to be attained by it, are then as important to be weighed, in considering the question of its exclusiveness, as the words in which it is granted.
In the first place, it is material to state (what has been already incidentally hinted at), that the right to seize and retake fugitive slaves and the duty to deliver them up, in whatever state of the Union they may be found, and, of course, the corresponding power in congress to use the appropriate means to enforce the right and duty, derive their whole validity and obligation exclusively from the constitution of the United States, and are there, for the first time, recognised and established in that peculiar character. Before the adoption of the constitution, no state had any power whatsoever over the subject, except within its own territorial limits, and could not bind the sovereignty or the legislation of other states. Whenever the right was acknowledged, or the duty enforced, in any state, it was as a matter of comity, and not as a matter of strict moral, political or international obligation or duty. Under the constitution, it is recognised as an absolute, positive right and duty, pervading the whole Union with an equal and supreme force, uncontrolled and uncontrollable by state sovereignty or state legislation. It it, therefore, in a just sense, a new and positive right, independent of comity, confined to no territorial limits, and bounded by no state institutions or policy. The natural inference deductible from this consideration certainly is, in the absence of any positive delegation of power to the state legislatures, that it belongs to the legislative department of the national government, to which it owes its origin and establishment. It would be a strange anomaly, and forced construction, to supose, that the national government meant to rely for the due fulfilment of its own proper duties, and the rights it intended to secure, upon state legislation, and not upon that of the Union. A fortiori, it would be more objectionable, to suppose, that a power, which was to be the same throughout the Union, should be confided to state sovereignty, which could not rightfully act beyond its own territorial limits.
In the next place, the nature of the provision and the objects to be attained by it, require that it should be controlled by one and the same will, and act uniformly by the same system of regulations throughout the Union. If, then, the states have a right, in the absence of legislation by congress, to act upon the subject, each state is at liberty to prescribe just such regulations as suit its own policy, local convenience and local feelings. The legislation of one state may not only be different from, but utterly repugnant to and incompatible with, that of another. The time and mode, and limitation of the remedy, the proofs of the title, and all other incidents applicable thereto, may be prescribed in one state, which are rejected or disclaimed in another. One state may require the owner to sue in one mode, another, in a different mode. One state may make a statute of limitations as to the remedy, in its own tribunals, short and summary; another may prolong the period, and yet restrict the proofs. Nay, some states may utterly refuse to act upon the subject of all; and others may refuse to open its courts to any remedies in rem, because they would interfere with their own domestic policy, institutions or habits. The right, therefore, would never, in a practical sense, be the same in all the states. It would have no unity of purpose, or uniformity of operation. The duty might be enforced in some states; retarded or limited in others; and denied, as compulsory, in many, if not in all. Consequences like these must have been foreseen as very likely to occur in the non-slave-holding states, where legislation, if not silent on the subject, and purely voluntary, could scarcely be presumed to be favorable to the exercise of the rights of the owner.
It is scarcely conceivable, that the slave-holding states would have been satisfied with leaving to the legislation of the non-slave-holding states, a power of regulation, in the absence of that of congress, which would or might practically amount to a power to destroy the rights of the owner. If the argument, therefore, of a concurrent power in the states to act upon the subect-matter, in the absence of legislation by congress, be well founded; then, if congress had never acted at all, or if the act of congress should be repealed, without providing a substitute, there would be a resulting authorizity in each of the states to regulate the whole subject, at its pleasure, and to dole out its own remedial justice, or withhold it, at its pleasure, and according to its own views of policy and expediency. Surely, such a state of things never could have been intended, under such a solemn guarantee of right and duty. On the other hand, construe the right of legislation as exclusive in congress, and every evil and every danger vanishes. The right and the duty are then co-extensive and uniform in remedy and operation throughout the whole Union. The owner has the same security, and the same remedial justice, and the same exemption from state regulation and control, through however many states he may pass with his fugitive slave in his possession, in transitu to his own domicile. But upon the other supposition, the moment he passes the state line, he becomes amenable to the laws of another sovereignty, whose regulations may greatly embarrass or delay the exercise of his rights, and even be repugnant to those of the state where he first arrested the fugitive. Consequences like these show, that the nature and objects of the provisions imperiously require, that to make it effectual, it should be construed to be exclusive of state authority. We adopt the language of this court in Sturges v. Crowninshield, 4 Wheat. 193, and say, that 'it has never been supposed, that the concurrent power of legislation extended to every possible case in which its exercise by the states has not been expressly prohibited; the confusion of such a practice would be endless.' And we know no case in which the confusion and public inconvenience and mischiefs thereof could be more completely exemplified than the present.
These are some of the reasons, but by no means all, upon which we hold the power of legislation on this subject to be exclusive in congress. To guard, however, against any possible misconstruction of our views, it is proper to state, that we are by no means to be understood, in any manner whatsoever, to doubt or to interfere with the police power belonging to the states, in virtue of their general sovereignty. That police power extends over all subjects within territorial limits of the states, and has never been conceded to the United States. It is wholly distinguishable fom the right and duty secured by the provision now under consideration; which is exclusively derived from and secured by the constitution of the United States, and ows its whole efficacy thereto. We entertain no doubt whatsoever, that the states, in virtue of their general police power, possesses full jurisdiction to arrest and restrain runaway slaves, and remove them from their borders, and otherwise to secure themselves against their depredations and evil example, as they certainly may do in cases of idlers, vagabonds and paupers. The rights of the owners of fugitive slaves are in no just sense interfered with, or regulated, by such a course; and in many cases, the operations of this police power, although designed generally for other purposes, for protection, safety and peace of the state, may essentially promote and aid the interests of the owners. But such regulations can never be permitted to interfere with, or to obstruct, the just rights of the owner to reclaim his slave, derived from the constitution of the United States, or with the remedies prescribed by congress to aid and enforce the same.
Upon these grounds, we are of opinion, that the act of Pennsylvania upon which this indictment is founded, is unconstitutional and void. It purports to punish as a public offence against that state, the very act of seizing and removing a slave, by his master, which the constitution of the United States was designed to justify and uphold. The special verdict finds this fact, and the state courts have rendered judgment against the plaintiff in error upon that verdict. That judgment must, therefore, be reversed, and the cause remanded to the supreme court of Pennsylvania, with directions to carry into effect the judgment of this court rendered upon the special verdict, in favor of the plaintiff in error.
