Mr. Justice DANIEL.
 
     It may with truth be affirmed, that since the establishment
of the several communities now constituting the States of this
Confederacy, there never has been submitted to any tribunal
within its limits questions surpassing in importance those now
claiming the consideration of this court. Indeed it is difficult
to imagine, in connection with the systems of polity peculiar to
the United States, a conjuncture of graver import than that must
be, within which it is aimed to comprise, and to control, not
only the faculties and practical operation appropriate to the
American Confederacy as such, but also the rights and powers of
its separate and independent members, with reference alike to
their internal and domestic authority and interests, and the
relations they sustain to their confederates.
 
     To my mind it is evident, that nothing less than the
ambitious and far-reaching pretension to compass these objects of
vital concern, is either directly essayed or necessarily implied
in the positions attempted in the argument for the plaintiff in
error.
 
     How far these positions have any foundation in the nature of
the rights and relations of separate, equal, and independent
Governments, or in the provisions of our own Federal compact, or
the laws enacted under and in pursuance of the authority of that
compact, will be presently investigated.
 
     In order correctly to comprehend the tendency and force of
those positions, it is proper here succinctly to advert to the
facts upon which the questions of law propounded in the argument
have arisen.
 
     This was an action of trespass vi et armis, instituted in
the Circuit Court of the United States for the district of
Missouri, in the name of the plaintiff in error, a negro held as
a slave, for the recovery of freedom for himself, his wife, and
two children, also negroes.
 
     To the declaration in this case the defendant below, who is
also the defendant in error, pleaded in abatement that the court
could not take cognizance of the cause, because the plaintiff was
not a citizen of the State of Missouri, as averred in the
declaration, but was a negro of African descent, and that his
ancestors were of pure African blood, and were brought into this
country and sold as negro slaves; and hence it followed, from the
second section of the third article of the Constitution, which
creates the judicial power of the United States, with respect to
controversies between citizens of different States, that the
Circuit Court could not take cognizance of the action.
 
     To this plea in abatement, a demurrer having been interposed
on behalf of the plaintiff, it was sustained by the court. After
the decision sustaining the demurrer, the defendant, in pursuance
of a previous agreement between counsel, and with the leave of
the court, pleaded in bar of the action: 1st, not guilty; 2dly,
that the plaintiff was a negro slave, the lawful property of the
defendant, and as such the defendant gently laid his hands upon
him, and thereby had only restrained him, as the defendant had a
right to do; 3dly, that with respect to the wife and daughters of
the plaintiff, in the second and third counts of the declaration
mentioned, the defendant had, as to them, only acted in the same
manner, and in virtue of the same legal right.
 
     Issues having been joined upon the above pleas in bar, the
following statement, comprising all the evidence in the cause,
was agreed upon and signed by the counsel of the respective
parties, viz:
 
          "In the year 1834, the plaintiff was a negro slave
     belonging to Doctor Emerson, who was a surgeon in the
     army of the United States. In that year, 1834, said Dr.
     Emerson took the plaintiff from the State of Missouri
     to the military post at Rock Island, in the State of
     Illinois, and held him there as a slave until the month
     of April or May, 1836. At the time last mentioned, said
     Dr. Emerson removed the plaintiff from said military
     post at Rock Island to the military post at Fort
     Snelling, situate on the west bank of the Mississippi
     river, in the Territory known as Upper Louisiana,
     acquired by the United States of France, and situate
     north of the latitude of thirty-six degrees thirty
     minutes north, and north of the State of Missouri. Said
     Dr. Emerson held the plaintiff in slavery at said Fort
     Snelling, from said last-mentioned date until the year
     1838.
 
          "In the year 1835, Harriet, who is named in the
     second count of the plaintiff's declaration, was the
     negro slave of Major Taliaferro, who belonged to the
     army of the United States. In that year, 1835, said
     Major Taliaferro took said Harriet to said Fort
     Snelling, a military post situated as hereinbefore
     stated, and kept her there as a slave until the year
     1836, and then sold and delivered her as a slave at
     said Fort Snelling unto the said Dr. Emerson,
     hereinbefore named. Said Dr. Emerson held said Harriet
     in slavery at said Fort Snelling until the year 1838.
 
          "In the year 1836, the plaintiff and said Harriet,
     at said Fort Snelling, with the consent of said Dr.
     Emerson, who then claimed to be their master and owner,
     intermarried, and took each other for husband and wife.
     Eliza and Lizzie, named in the third count of the
     plaintiff's declaration, are the fruit of that
     marriage. Eliza is about fourteen years old, and was
     born on board the steamboat Gipsey, north of the north
     line of the State of Missouri, and upon the river
     Mississippi. Lizzie is about seven years old, and was
     born in the State of Missouri, at a military post
     called Jefferson barracks.
 
          "In the year 1838, said Dr. Emerson removed the
     plaintiff and said Harriet, and their said daughter
     Eliza, from said Fort Snelling to the State of
     Missouri, where they have ever since resided.
 
          "Before the commencement of this suit, said Dr.
     Emerson sold and conveyed the plaintiff, said Harriet,
     Eliza, and Lizzie, to the defendant, as slaves, and the
     defendant has ever since claimed to hold them and each
     of them as slaves.
 
          "At the times mentioned in the plaintiff's
     declaration, the defendant, claiming to be owner as
     aforesaid, laid his hands upon said plaintiff, Harriet,
     Eliza, and Lizzie, and imprisoned them, doing in this
     respect, however, no more than what he might lawfully
     do if they were of right his slaves at such times.
 
          "Further proof may be given on the trial for
     either party.
 
     "R. M. FIELD, for Plaintiff.
 
     "H. A. GARLAND, for Defendant.
 
          "It is agreed that Dred Scott brought suit for his
     freedom in the Circuit Court of St. Louis county; that
     there was a verdict and judgment in his favor; that on
     a writ of error to the Supreme Court, the judgment
     below was reversed, and the cause remanded to the
     Circuit Court, where it has been continued to await the
     decision of this case.
 
     "FIELD, for Plaintiff.
 
     "GARLAND, for Defendant."
 
 
     Upon the aforegoing agreed facts, the plaintiff prayed the
court to instruct the jury that they ought to find for the
plaintiff, and upon the refusal of the instruction thus prayed
for, the plaintiff excepted to the court's opinion. The court
then, upon the prayer of the defendant, instructed the jury, that
upon the facts of this case agreed as above, the law was with the
defendant. To this opinion, also, the plaintiff's counsel
excepted, as he did to the opinion of the court denying to the
plaintiff a new trial after the verdict of the jury in favor of
the defendant.
 
     The question first in order presented by the record in this
cause, is that which arises upon the plea in abatement, and the
demurrer to that plea; and upon this question it is my opinion
that the demurrer should have been overruled, and the plea
sustained.
 
     On behalf of the plaintiff it has been urged, that by the
pleas interposed in bar of a recovery in the court below, (which
pleas both in fact and in law are essentially the same with the
objections averred in abatement,) the defence in abatement has
been displaced or waived; that it could therefore no longer be
relief on in the Circuit Court, and cannot claim the
consideration of this court in reviewing this cause. This
position is regarded as wholly untenable. On the contrary, it
would seem to follow conclusively from the peculiar character of
the courts of the United States, as organized under the
Constitution and the statutes, and as defined by numerous and
unvarying adjudications from this bench, that there is not one of
those courts whose jurisdiction and powers can be deduced from
mere custom or tradition; not one, whose jurisdiction and powers
must not be traced palpably to, and invested exclusively by, the
Constitution and statutes of the United States; not one that is
not bound, therefore, at all times, and at all stages of its
proceedings, to look to and to regard the special and declared
extent and bounds of its commission and authority. There is no
such tribunal of the United States as a court of general
jurisdiction, in the sense in which that phrase is applied to the
superior courts under the common law; and even with respect to
the courts existing under that system, it is a well-settled
principle, that consent can never give jurisdiction.
 
     The principles above stated, and the consequences regularly
deducible from them, have, as already remarked, been repeatedly
and unvaryingly propounded from this bench. Beginning with the
earliest decisions of this court, we have the cases of Bingham v.
Cabot et al., (3 Dallas, 382;) Turner v. Eurille, (4 Dallas, 7;)
Abercrombie v. Dupuis et al., (1 Cranch, 343;) Wood v. Wagnon, (2
Cranch, 9;) The United States v. The brig Union et al., (4
Cranch, 216;) Sullivan v. The Fulton Steamboat Company, (6
Wheaton, 450;) Mollan et al. v. Torrence, (9 Wheaton, 537;) Brown
v. Keene, (8 Peters, 112,) and Jackson v. Ashton, (8 Peters,
148;) ruling, in uniform and unbroken current, the doctrine that
it is essential to the jurisdiction of the courts of the United
States, that the facts upon which it is founded should appear
upon the record. Nay, to such an extent and so inflexibly has
this requisite to the jurisdiction been enforced, that in the
case of Capron v. Van Noorden, (2 Cranch, 126,) it is declared,
that the plaintiff in this court may assign for error his own
omission in the pleadings in the court below, where they go to
the jurisdiction. This doctrine has been, if possible, more
strikingly illustrated in a later decision, the case of The State
of Rhode Island v. The State of Massachusetts, in the 12th of
Peters.
 
     In this case, on page 718 of the volume, this court, with
reference to a motion to dismiss the cause for want of
jurisdiction, have said: "However late this objection has been
made, or may be made, in any cause in an inferior or appellate
court of the United States, it must be considered and decided
before any court can move one farther step in the cause, as any
movement is necessarily to exercise the jurisdiction.
Jurisdiction is the power to hear and determine the
subject-matter in controversy between the parties to a suit; to
adjudicate or exercise any judicial power over them. The question
is, whether on the case before the court their action is judicial
or extra-judicial; with or without the authority of law to render
a judgment or decree upon the rights of the litigant parties. A
motion to dismiss a cause pending in the courts of the United
States, is not analogous to a plea to the jurisdiction of a court
of common law or equity in England; there, the superior courts
have a general jurisdiction over all persons within the realm,
and all causes of action between them. It depends on the
subject-matter, whether the jurisdiction shall be exercised by a
court of law or equity; but that court to which it appropriately
belongs can act judicially upon the party and the subject of the
suit, unless it shall be made apparent to the court that the
judicial determination of the case has been withdrawn from the
court of general jurisdiction to an inferior and limited one. It
is a necessary presumption that the court of general jurisdiction
can act upon the given case, when nothing to the contrary
appears; hence has arisen the rule that the party claiming an
exemption from its process must set out the reason by a special
plea in abatement, and show that some inferior court of law or
equity has the exclusive cognizance of the case, otherwise the
superior court must proceed in virtue of its general
jurisdiction. A motion to dismiss, therefore, cannot be
entertained, as it does not disclose a case of exception; and if
a plea in abatement is put in, it must not only make out the
exception, but point to the particular court to which the case
belongs. There are other classes of cases where the objection to
the jurisdiction is of a different nature, as on a bill in
chancery, that the subject-matter is cognizable only by the King
in Council, or that the parties defendant cannot be brought
before any municipal court on account of their sovereign
character or the nature of the controversy; or to the very common
cases which present the question, whether the cause belong to a
court of law or equity. To such cases, a plea in abatement would
not be applicable, because the plaintiff could not sue in an
inferior court. The objection goes to a denial of any
jurisdiction of a municipal court in the one class of cases, and
to the jurisdiction of any court of equity or of law in the
other, on which last the court decides according to its
discretion.
 
          "An objection to jurisdiction on the ground of
     exemption from the process of the court in which the
     suit is brought, or the manner in which a defendant is
     brought into it, is waived by appearance and pleading
     to issue; but when the objection goes to the power of
     the court over the parties or the subject-matter, the
     defendant need not, for he cannot, give the plaintiff a
     better writ. Where an inferior court can have no
     jurisdiction of a case of law or equity, the ground of
     objection is not taken by plea in abatement, as an
     exception of the given case from the otherwise general
     jurisdiction of the court; appearance does not cure the
     defect of judicial power, and it may be relied on by
     plea, answer, demurrer, or at the trial or hearing. As
     a denial of jurisdiction over the subject-matter of a
     suit between parties within the realm, over which and
     whom the court has power to act, cannot be successful
     in an English court of general jurisdiction, a motion
     like the present could not be sustained consistently
     with the principles of its constitution. But as this
     court is one of limited and special original
     jurisdiction, its action must be confined to the
     particular cases, controversies, and parties, over
     which the Constitution and laws have authorized it to
     act; any proceeding without the limits prescribed is
     coram non judice, and its action a nullity. And whether
     the want or excess of power is objected by a party, or
     is apparent to the court, it must surcease its action
     or proceed extra-judicially."
 
 
     In the constructing of pleadings either in abatement or in
bar, every fact or position constituting a portion of the public
law, or of known or general history, is necessarily implied. Such
fact or position need not be specially averred and set forth; it
is what the world at large and every individual are presumed to
know -- nay, are bound to know and to be governed by.
     If, on the other hand, there exist facts or circumstances by
which a particular case would be withdrawn or exempted from the
influence of public law or necessary historical knowledge, such
facts and circumstances form an exception to the general
principle, and these must be specially set forth and established
by those who would avail themselves of such exception.
 
     Now, the following are truths which a knowledge of the
history of the world, and particularly of that of our own
country, compels us to know -- that the African negro race never
have been acknowledged as belonging to the family of nations;
that as amongst them there never has been known or recognized by
the inhabitants of other countries anything partaking of the
character of nationality, or civil or political polity; that this
race has been by all the nations of Europe regarded as subjects
of capture or purchase; as subjects of commerce or traffic; and
that the introduction of that race into every section of this
country was not as members of civil or political society, but as
slaves, as property in the strictest sense of the term.
 
     In the plea in abatement, the character or capacity of
citizen on the part of the plaintiff is denied; and the causes
which show the absence of that character or capacity are set
forth by averment. The verity of those causes, according to the
settled rules of pleading, being admitted by the demurrer, it
only remained for the Circuit Court to decide upon their legal
sufficiency to abate the plaintiff's action. And it now becomes
the province of this court to determine whether the plaintiff
below, (and in error here,) admitted to be a negro of African
descent, whose ancestors were of pure African blood, and were
brought into this country and sold as negro slaves -- such being
his status, and such the circumstances surrounding his position
-- whether he can, by correct legal induction from that status
and those circumstances, be clothed with the character and
capacities of a citizen of the State of Missouri?
 
     It may be assumed as a postulate, that to a slave, as such,
there appertains and can appertain no relation, civil or
political, with the State or the Government. He is himself
strictly property, to be used in subserviency to the interests,
the convenience, or the will, of his owner; and to suppose, with
respect to the former, the existence of any privilege or
discretion, or of any obligation to others incompatible with the
magisterial rights just defined, would be by implication, if not
directly, to deny the relation of master and slave, since none
can possess and enjoy, as his own, that which another has a
paramount right and power to withhold. Hence it follows,
necessarily, that a slave, the peculium or property of a master,
and possessing within himself no civil nor political rights or
capacities, cannot be a CITIZEN. For who, it may be asked, is a
citizen? What do the character and status of citizen import?
Without fear of contradiction, it does not import the condition
of being private property, the subject of individual power and
ownership. Upon a principle of etymology alone, the term citizen,
as derived from civitas, conveys the ideas of connection or
identification with the State or Government, and a participation
of its functions. But beyond this, there is not, it is believed,
to be found, in the theories of writers on Government, or in any
actual experiment heretofore tried, an exposition of the term
citizen, which has not been understood as conferring the actual
possession and enjoyment, or the perfect right of acquisition and
enjoyment, of an entire equality of privileges, civil and
political.
 
     Thus Vattel, in the preliminary chapter to his Treatise on
the Law of Nations, says: "Nations or States are bodies politic;
societies of men united together for the purpose of promoting
their mutual safety and advantage, by the joint efforts of their
mutual strength. Such a society has her affairs and her
interests; she deliberates and takes resolutions in common; thus
becoming a moral person, who possesses an understanding and a
will peculiar to herself." Again, in the first chapter of the
first book of the Treatise just quoted, the same writer, after
repeating his definition of a State, proceeds to remark, that,
"from the very design that induces a number of men to form a
society, which has its common interests and which is to act in
concert, it is necessary that there should be established a
public authority, to order and direct what is to be done by each,
in relation to the end of the association. This political
authority is the sovereignty." Again this writer remarks: "The
authority of all over each member essentially belongs to the body
politic or the State."
 
     By this same writer it is also said: "The citizens are the
members of the civil society; bound to this society by certain
duties, and subject to its authority; they equally participate in
its advantages. The natives, or natural-born citizens, are those
born in the county, of parents who are citizens. as society
cannot perpetuate itself otherwise than by the children of the
citizens, those children naturally follow the condition of their
parents, and succeed to all their rights." Again: "I say, to be
of the country, it is necessary to be born of a person who is a
citizen; for if he be born there of a foreigner, it will be only
the place of his birth, and not his country. The inhabitants, as
distinguished from citizens, are foreigners who are permitted to
settle and stay in the country." (Vattel, Book 1, cap. 19, p.
101.)
 
     From the views here expressed, and they seem to be
unexceptionable, it must follow, that with the slave, with one
devoid of rights or capacities, civil or political, there could
be no pact; that one thus situated could be no party to, or actor
in, the association of those possessing free will, power,
discretion. He could form no part of the design, no constituent
ingredient or portion of a society based upon common, that is,
upon equal interests and powers. He could not at the same time be
the sovereign and the slave.
 
     But it has been insisted, in argument, that the emancipation
of a slave, effected either by the direct act and assent of the
master, or by causes operating in contravention of his will,
produces a change in the status or capacities of the slave, such
as will transform him from a mere subject of property, into a
being possessing a social, civil, and political equality with a
citizen. In other words, will make him a citizen of the State
within which he was, previously to his emancipation, a slave.
 
     It is difficult to conceive by what magic the mere surcease
or renunciation of an interest in a subject of property, by an
individual possessing that interest, can alter the essential
character of that property with respect to persons or communities
unconnected with such renunciation. Can it be pretended that an
individual in any State, by his singly act, though voluntarily or
designedly performed, yet without the co-operation or warrant of
the Government, perhaps in opposition to its policy or its
guaranties, can create a citizen of that State? Much more
emphatically may it be asked, how such a result could be
accomplished by means wholly extraneous, and entirely foreign to
the Government of the State? The argument thus urged must lead to
these extraordinary conclusions. It is regarded at once as wholly
untenable, and as unsustained by the direct authority or by the
analogies of history.
 
     The institution of slavery, as it exists and has existed
from the period of its introduction into the United States,
though more humane and mitigated in character than was the same
institution, either under the republic or the empire of Rome,
bears, both in its tenure and in the simplicity incident to the
mode of its exercise, a closer resemblance to Roman slavery than
it does to the condition of villanage, as it formerly existed in
England. Connected with the latter, there were peculiarities,
from custom or positive regulation, which varied it materially
from the slavery of the Romans, or from slavery at any period
within the United States.
 
     But with regard to slavery amongst the Romans, it is by no
means true that emancipation, either during the republic or the
empire, conferred, by the act itself, or implied, the status or
the rights of citizenship.
 
     The proud title of Roman citizen, with the immunities and
rights incident thereto, and as contradistinguished alike from
the condition of conquered subjects or of the lower grades of
native domestic residents, was maintained throughout the duration
of the republic, and until a late period of the eastern empire,
and at last was in effect destroyed less by an elevation of the
inferior classes than by the degradation of the free, and the
previous possessors of rights and immunities civil and political,
to the indiscriminate abasement incident to absolute and simple
despotism.
 
     By the learned and elegant historian of the Decline and Fall
a the Roman Empire, we are told that "In the decline of the Roman
empire, the proud distinctions of the republic were gradually
abolished; and the reason or instinct of Justinian completed the
simple form of an absolute monarchy. The emperor could not
eradicate the popular reverence which always waits on the
possession of hereditary wealth or the memory of famous
ancestors. He delighted to honor with titles and emoluments his
generals, magistrates, and senators, and his precarious
indulgence communicated some rays of their glory to their wives
and children. But in the eye of the law all Roman citizens were
equal, and all subjects of the empire were citizens of Rome. That
inestimable character was degraded to an obsolete and empty name.
The voice of a Roman could no longer enact his laws, or create
the annual ministers of his powers; his constitutional rights
might have checked the arbitrary will of a master; and the bold
adventurer from Germany or Arabia was admitted with equal favor
to the civil and military command which the citizen alone had
been once entitled to assume over the conquests of his fathers.
The first Caesers had scrupulously guarded the distinction of
ingenuous and servile birth, which was decided by the condition
of the mother. The slaves who were liberated by a generous master
immediately entered into the middle class of libertini or
freedmen; but they could never be enfranchised from the duties of
obedience and gratitude; whatever were the fruits of their
industry, their patron and his family inherited the third part,
or even the whole of their fortune, if they died without children
and without a testament. Justinian respected the rights of
patrons, but his indulgence removed the badge of disgrace from
the two inferior orders of freedmen; whoever ceased to be a
slave, obtained without reserve or delay the station of a
citizen; and at length the dignity of an ingenuous birth was
created or supposed by the omnipotence of the emperor."[n1]
 
     n1   Vide Gibbons's Decline and Fall of the Roman
          Empire. London edition of 1825, vol. 3d, chap. 44,
          p. 183.
 
 
     The above account of slavery and its modifications will be
found in strictest conformity with the Institutes of Justinian.
Thus, book 1st, title 3d, it is said: "The first general division
of persons in respect to their rights is into freemen and
slaves." The same title, sec. 4th: "Slaves are born such, or
become so. They are born such of bondwomen; they become so either
by the law of nations, as by capture, or by the civil law.
Section 5th: "In the condition of slaves there is no diversity;
but among free persons there are many. Thus some are ingenui or
freemen, others libertini or freedmen."
 
     Tit. 4th. DE INGENUIS. -- "A freeman is one who is born free
by being born in matrimony, of parents who both are free, or both
freed; or of parents one free and the other freed. But one born
of a free mother, although the father be a slave or unknown. is
free."
 
     Tit. 5th. DE LIBERTINIS. -- "Freedmen are those who have
been manumitted from just servitude."
 
 
     Section third of the same title states that "freedmen were
formerly distinguished by a threefold division." But the emperor
proceeds to say: "Our piety leading us to reduce all things into
a better state, we have amended our laws, and reestablished the
ancient usage; for anciently liberty was simple and undivided --
that is, was conferred upon the slave as his manumittor possessed
it, admitting this single difference, that the person manumitted
became only a freed man, although his manumittor was a free man."
And he further declares: "We have made all freed men in general
become citizens of Rome, regarding neither the age of the
manumitted, nor the manumittor, nor the ancient forms of
manumission. We have also introduced many new methods by which
slaves may become Roman citizens."
 
     By the references above given it is shown, from the nature
and objects of civil and political associations, and upon the
direct authority of history, that citizenship was not conferred
by the simple fact of emancipation, but that such a result was
deduced therefrom in violation of the fundamental principles of
free political association; by the exertion of despotic will to
establish, under a false and misapplied denomination, one equal
and universal slavery; and to effect this result required the
exertions of absolute power -- of a power both in theory and
practice, being in its most plenary acceptation the SOVEREIGNTY,
THE STATE ITSELF -- it could not be produced by a less or
inferior authority, much less by the will or the act of one who,
with reference to civil and political rights, was himself a
slave. The master might abdicate or abandon his interest or
ownership in his property, but his act would be a mere
abandonment. It seems to involve an absurdity to impute to it the
investiture of rights which the sovereignty alone had power to
impart. There is not perhaps a community in which slavery is
recognized, in which the power of emancipation and the modes of
its exercise are not regulated by law -- that is, by the
sovereign authority; and none can fail to comprehend the
necessity for such regulation, for the preservation of order, and
even of political and social existence.
 
     By the argument for the plaintiff in error, a power equally
despotic is vested in every member of the association, and the
most obscure or unworthy individual it comprises may arbitrarily
invade and derange its most deliberate and solemn ordinances. At
assumptions anomalous as these, so fraught with mischief and
ruin, the mind at once is revolted, and goes directly to the
conclusions, that to change or to abolish a fundamental principle
of the society, must be the act of the society itself -- of the
sovereignty; and that none other can admit to a participation of
that high attribute. It may further expose the character of the
argument urged for the plaintiff, to point out some of the
revolting consequences which it would authorize. If that argument
possesses any integrity, it asserts the power in any citizen, or
quasi citizen, or a resident foreigner of any one of the States,
from a motive either of corruption or caprice, not only to
infract the inherent and necessary authority of such State, but
also materially to interfere with the organization of the Federal
Government, and with the authority of the separate and
independent States. He may emancipate his negro slave, by which
process he first transforms that slave into a citizen of his own
State; he may next, under color of article fourth, section
second, of the Constitution of the United States, obtrude him,
and on terms of civil and political equality, upon any and every
State in this Union, in defiance of all regulations of necessity
or policy, ordained by those States for their internal happiness
or safety. Nay, more: this manumitted slave may, by a proceeding
springing from the will or act of his master alone, be mixed up
with the institutions of the Federal Government, to which he is
not a party, and in opposition to the laws of that Government
which, in authorizing the extension by naturalization of the
rights and immunities of citizens of the United States to those
not originally parties to the Federal compact, have restricted
that boon to free white aliens alone. If the rights and
immunities connected with or practiced under the institutions of
the United States can by any indirection be claimed or deduced
from sources or modes other than the Constitution and laws of the
United States, it follows that the power of naturalization vested
in Congress is not exclusive -- that it has in effect no
existence, but is repealed or abrogated.
 
     But it has been strangely contended that the jurisdiction of
the Circuit Court might be maintained upon the ground that the
plaintiff was a resident of Missouri, and that, for the purpose
of vesting the court with jurisdiction over the parties,
residence within the State was sufficient.
 
     The first, and to my mind a conclusive reply to this
singular argument is presented in the fact, that the language of
the Constitution restricts the jurisdiction of the courts to
cases in which the parties shall be citizens, and is entirely
silent with respect to residence. A second answer to this strange
and latitudinous notion is, that it so far stultifies the sages
by whom the Constitution was framed, as to impute to them
ignorance of the material distinction existing between
citizenship and mere residence or domicil, and of the well-known
facts, that a person confessedly an alien may be permitted to
reside in a country in which he can possess no civil or political
rights, or of which he is neither a citizen nor subject; and that
for certain purposes a man may have a domicil in different
countries, in no one of which he is an actual personal resident.
 
     The correct conclusions upon the question here considered
would seem to be these:
 
     That in the establishment of the several communities now the
States of this Union, and in the formation of the Federal
Government, the African was not deemed politically a person. He
was regarded and owned in every State in the Union as property
merely, and as such was not and could not be a party or an actor,
much less a peer in any compact or form of government established
by the States or the United States. That if, since the adoption
of the State Governments, he has been or could have been elevated
to the possession of political rights or powers, this result
could have been effected by no authority less potent than that of
the sovereignty -- the State -- exerted to that end, either in
the form of legislation, or in some other mode of operation. It
could certainly never have been accomplished by the will of an
individual operating independently of the sovereign power, and
even contravening and controlling that power. That so far as
rights and immunities appertaining to citizens have been defined
and secured by the Constitution and laws of the United States,
the African race is not and never was recognized either by the
language or purposes of the former; and it has been expressly
excluded by every act of Congress providing for the creation of
citizens by naturalization, these laws, as has already been
remarked, being restricted to free white aliens exclusively.
 
     But it is evident that, after the formation of the Federal
Government by the adoption of the Constitution, the highest
exertion of State power would be incompetent to bestow a
character or status created by the Constitution, or conferred in
virtue of its authority only. Upon those, therefore, who were not
originally parties to the Federal compact, or who are not
admitted and adopted as parties thereto, in the mode prescribed
by its paramount authority, no State could have power to bestow
the character or the rights and privileges exclusively reserved
by the States for the action of the Federal Government by that
compact.
 
     The States, in the exercise of their political power, might,
with reference to their peculiar Government and jurisdiction,
guaranty the rights of person and property. and the enjoyment of
civil and political privileges, to those whom they should be
disposed to make the objects of their bounty; but they could not
reclaim or exert the powers which they had vested exclusively in
the Government of the United States. They could not add to or
change in any respect the class of persons to whom alone the
character of citizen of the United States appertained at the time
of the adoption of the Federal Constitution. They could not
create citizens of the United States by any direct of indirect
proceeding.
 
     According to the view taken of the law, as applicable to the
demurrer to the plea in abatement in this cause, the questions
subsequently raised upon the several pleas in bar might be passed
by, as requiring neither a particular examination, nor an
adjudication directly upon them. But as these questions are
intrinsically of primary interest and magnitude, and have been
elaborately discussed in argument, and as with respect to them
the opinions of a majority of the court, including my own, are
perfectly coincident, to me it seems proper that they should here
be fully considered, and, so far as it is practicable for this
court to accomplish such an end, finally put to rest.
 
     The questions then to be considered upon the several pleas
in bar, and upon the agreed statement of facts between the
counsel, are: 1st. Whether the admitted master and owner of the
plaintiff, holding him as his slave in the State of Missouri, and
in conformity with his rights guarantied to him by the laws of
Missouri then and still in force, by carrying with him for his
own benefit and accommodation, and as his own slave, the person
of the plaintiff into the State of Illinois, within which State
slavery had been prohibited by the Constitution thereof, and by
retaining the plaintiff during the commorancy of the master
within the State of Illinois, had, upon his return with his slave
into the State of Missouri, forfeited his rights as master, by
reason of any supposed operation of the prohibitory provision in
the Constitution of Illinois, beyond the proper territorial
jurisdiction of the latter State? 2d. Whether a similar removal
of the plaintiff by his master from the State of Missouri, and
his retention in service at a point included within no State, but
situated north of thirty-six degrees thirty minutes of north
latitude, worked a forfeiture of the right of property of the
master, and the manumission of the plaintiff?
 
     In considering the first of these questions, the acts or
declarations of the master, as expressive of his purpose to
emancipate, may be thrown out of view, since none will deny the
right of the owner to relinquish his interest in any subject of
property, at any time or in any place. The inquiry here bears no
relation to acts or declarations of the owner as expressive of
his intent or purpose to make such a relinquishment; it is simply
a question whether, irrespective of such purpose, and in
opposition thereto, that relinquishment can be enforced against
the owner of property within his own country, in defiance of
every guaranty promised by its laws; and this through the
instrumentality of a claim to power entirely foreign and
extraneous with reference to himself, to the origin and
foundation of his title, and to the independent authority of his
country. A conclusive negative answer to such an inquiry is at
once supplied, by announcing a few familiar and settled
principles and doctrines of public law.
 
     Vattel, in his chapter on the general principles of the laws
of nations, section 15th, tells us, that "nations being free and
independent of each other in the same manner that men are
naturally free and independent, the second general law of their
society is, that each nation should be left in the peaceable
enjoyment of that liberty which she inherits from nature."
 
     "The natural society of nations," says this writer, "cannot
subsist unless the natural rights of each be respected." In
section 16th he says, "as a consequence of that liberty and
independence, it exclusively belongs to each nation to form her
own judgment of what her conscience prescribes for her -- of what
it is proper or improper for her to do; and of course it rests
solely with her to examine and determine whether she can perform
any office for another nation without neglecting the duty she
owes to herself. In all cases, therefore, in which a nation has
the right of judging what her duty requires, no other nation can
compel her to act in such or such a particular manner, for any
attempt at such compulsion would be an infringement on the
liberty of nations." Again, in section 18th, of the same chapter,
"nations composed of men, and considered as so many free persons
living together in a state of nature, are naturally equal, and
inherit from nature the same obligations and rights. Power or
weakness does not produce any difference. A small republic is no
less a sovereign state than the most powerful kingdom."
 
     So, in section 20: "A nation, then, is mistress of her own
actions, so long as they do not affect the proper and perfect
rights of any other nation -- so long as she is only internally
bound, and does not lie under any external and perfect
obligation. If she makes an ill use of her liberty, she is guilty
of a breach of duty; but other nations are bound to acquiesce in
her conduct, since they have no right to dictate to her. Since
nations are free, independent, and equal, and since each
possesses the right of judging, according to the dictates of her
conscience, what conduct she is to pursue, in order to fulfil her
duties, the effect of the whole is to produce, at least
externally, in the eyes of mankind, a perfect equality of rights
between nations, in the administration of their affairs, and in
the pursuit of their pretensions, without regard to the intrinsic
justice of their conduct, of which others have no right to form a
definitive judgment."
 
     Chancellor Kent, in the 1st volume of his Commentaries,
lecture 2d, after collating the opinions of Grotius, Heineccius,
Vattel, and Rutherford, enunciates the following positions as
sanctioned by these and other learned publicists, viz: that
"nations are equal in respect to each other, and entitled to
claim equal consideration for their rights, whatever may be their
relative dimensions or strength, or however greatly they may
differ in government, religion, or manners. This perfect equality
and entire independence of all distinct States is a fundamental
principle of public law. It is a necessary consequence of this
equality, that each nation has a right to govern itself as it may
think proper, and no one nation is entitled to dictate a form of
government or religion, or a course of internal policy, to
another." This writer gives some instances of the violation of
this great national immunity, and amongst them the constant
interference by the ancient Romans, under the pretext of settling
disputes between their neighbors, but with the real purpose of
reducing those neighbors to bondage; the interference of Russia,
Prussia, and Austria, for the dismemberment of Poland; the more
recent invasion of Naples by Austria in 1821, and of Spain by the
French Government in 1823, under the excuse of suppressing a
dangerous spirit of internal revolution and reform.
 
     With reference to this right of self-government in
independent sovereign States, an opinion has been expressed,
which, whilst it concedes this right as inseparable from and as a
necessary attribute of sovereignty and independence, asserts
nevertheless some implied and paramount authority of a supposed
international law, to which this right of self-government must be
regarded and exerted as subordinate; and from which independent
and sovereign States can be exempted only by a protest, or by
some public and formal rejection of that authority. With all
respect for those by whom this opinion has been professed, I am
constrained to regard it as utterly untenable, as palpably
inconsistent, and as presenting in argument a complete felo de
se.
 
     Sovereignty, independence, and a perfect right of
self-government, can signify nothing less than a superiority to
and an exemption from all claims by any extraneous power, however
expressly they may be asserted, and render all attempts to
enforce such claims merely attempts at usurpation. Again, could
such claims from extraneous sources be regarded as legitimate,
the effort to resist or evade them, by protest or denial, would
be as irregular and unmeaning as it would be futile. It could in
no wise affect the question of superior right. For the position
here combatted, no respectable authority has been, and none it is
thought can be adduced. It is certainly irreconcilable with the
doctrines already cited from the writers upon public law.
 
     Neither the case of Lewis Somersett, (Howell's State Trials,
vol. 20,) so often vaunted as the proud evidence of devotion to
freedom under a Government which has done as much perhaps to
extend the reign of slavery as all the world besides; not does
any decision founded upon the authority of Somersett's case, when
correctly expounded, assail or impair the principle of national
equality enunciated by each and all of the publicists already
referred to. In the case of Somersett, although the applicant for
the habeas corpus and the individual claiming property in that
applicant were both subjects and residents within the British
empire, yet the decision cannot be correctly understood as ruling
absolutely and under all circumstances against the right of
property in the claimant. That decision goes no farther than to
determine, that within the realm of England there was no
authority to justify the detention of an individual in private
bondage. If the decision in Somersett's case had gone beyond this
point, it would have presented the anomaly of a repeal by laws
enacted for and limited in their operation to the realm alone, of
other laws and institutions established for places and subjects
without the limits of the realm of England; laws and institutions
at that very time, and long subsequently, sanctioned and
maintained under the authority of the British Government, and
which the full and combined action of the King and Parliament was
required to abrogate.
 
     But could the decision in Somersett's case be correctly
interpreted as ruling the doctrine which it has been attempted to
deduce from it, still that doctrine must be considered as having
been overruled by the lucid and able opinion of Lord Stowell in
the more recent case of the slave Grace, reported in the second
volume of Haggard p. 94; in which opinion, whilst it is conceded
by the learned judge that there existed no power to coerce the
slave whilst in England, that yet, upon her return to the island
of Antigua, her status as a slave was revived, or, rather, that
the title of the owner to the slave as property had never been
extinguished, but had always existed in that island. If the
principle of this decision be applicable as between different
portions of one and the same empire, with how much more force
does it apply as between nations or Governments entirely
separate, and absolutely independent of each other? For in this
precise attitude the States of this Union stand with reference to
this subject, and with reference to the tenure of every
description of property vested under their laws and held within
their territorial jurisdiction.
 
     A strong illustration of the principle ruled by Lord
Stowell, and of the effect of that principle even in a case of
express contract, is seen in the case of Lewis v. Fullerton,
decided by the Supreme Court of Virginia, and reported in the
first volume of Randolph, p. 15. The case was this: A female
slave, the property of a citizen of Virginia, whilst with her
master in the State of Ohio, was taken from his possession under
a writ of habeas corpus, and set at liberty. Soon, or immediately
after, by agreement between this slave and her master, a deed was
executed in Ohio by the latter, containing a stipulation that
this slave should return to Virginia, and, after a service of two
years in that State, should there be free. The law of Virginia
regulating emancipation required that deeds of emancipation
should, within a given time from their date, be recorded in the
court of the county in which the grantor resided, and declared
that deeds with regard to which this requisite was not complied
with should be void. Lewis, an infant son of this female, under
the rules prescribed in such cases, brought an action, in forma
pauperis, in one of the courts of Virginia, for the recovery of
his freedom, claimed in virtue of the transactions above
mentioned. Upon an appeal to the Supreme Court from a judgment
against the plaintiff, Roane, Justice, in delivering the opinion
of the court, after disposing of other questions discussed in
that case, remarks:
 
     "As to the deed of emancipation contained in the record,
that deed, taken in connection with the evidence offered in
support of it, shows that it had a reference to the State of
Virginia; and the testimony shows that it formed a part of this
contract, whereby the slave Milly was to be brought back (as she
was brought back) into the State of Virginia.Her object was
therefore to secure her freedom by the deed within the State of
Virginia, after the time should have expired for which she had
indented herself, and when she should be found abiding within the
State of Virginia.
 
     "If, then, this contract had an eye to the State of Virginia
for its operation and effect, the lex loci ceases to operate. In
that case it must, to have its effect, conform to the laws of
Virginia. It is insufficient under those laws to effectuate an
emancipation, for want of a due recording in the county court, as
was decided in the case of Givens v. Mann, in this court. It is
also ineffectual within the Commonwealth of Virginia for another
reason. The lex loci is also to be taken subject to the
exception, that it is not to be enforced in another country, when
it violates some moral duty or the policy of that country, or is
not consistent with a positive right secured to a third person or
party by the laws of that country in which it is sought to be
enforced. In such a case we are told, 'magis jus nostrum, quam
jus alienum servemus.'" (Huberus, tom. 2, lib. 1, tit. 3; 2
Fontblanque, p. 444.) "That third party in this instance is the
Commonwealth of Virginia, and her policy and interests are also
to be attended to. These turn the scale against the lex loci in
the present instance."
 
     The second or last-mentioned position assumed for the
plaintiff under the pleas in bar, as it rests mainly if not
solely upon the provision of the act of Congress of March 6,
1820, prohibiting slavery in Upper Louisiana north of thirty-six
degrees thirty minutes north latitude, popularly called the
Missouri Compromise, that assumption renews the question,
formerly so zealously debated, as to the validity of the
provision in the act of Congress, and upon the constitutional
competency of Congress to establish it.
 
     Before proceeding, however, to examine the validity of the
prohibitory provision of the law, it may, so far as the rights
involved in this cause are concerned, be remarked, that conceding
to that provision the validity of a legitimate exercise of power,
still this concession could by no rational interpretation imply
the slightest authority for its operation beyond the territorial
limits comprised within its terms; much less could there be
inferred from it a power to destroy or in any degree to control
rights, either of person or property, entirely within the bounds
of a distinct and independent sovereignty -- rights invested and
fortified by the guaranty of that sovereignty. These surely would
remain in all their integrity, whatever effect might be ascribed
to the prohibition within the limits defined by its language.
 
     But, beyond and in defiance of this conclusion, inevitable
and undeniable as it appears, upon every principle of justice or
sound induction, it has been attempted to convert this
prohibitory provision of the act of 1820 not only into a weapon
with which to assail the inherent -- the necessarily inherent --
powers of independent sovereign Governments, but into a mean of
forfeiting that equality of rights and immunities which are the
birthright or the donative from the Constitution of every citizen
of the United States within the length and breadth of the nation.
In this attempt, there is asserted a power in Congress, whether
from incentives of interest, ignorance, faction, partiality, or
prejudice, to bestow upon a portion of the citizens of this
nation that which is the common property and privilege of all --
the power, in fine, of confiscation, in retribution for no
offence, or, if for an offence, for that of accidental locality
only.
 
     It may be that, with respect to future cases, like the one
now before the court, there is felt an assurance of the impotence
of such a pretension; still, the fullest conviction of that
result can impart to it no claim to forbearance, nor dispense
with the duty of antipathy and disgust at its sinister aspect,
whenever it may be seen to scowl upon the justice, the order, the
tranquillity, and fraternal feeling, which are the surest, may,
the only means, of promoting or preserving the happiness and
prosperity of the nation, and which were the great and efficient
incentives to the formation of this Government.
 
     The power of Congress to impose the prohibition in the
eighth section of the act of 1820 has been advocated upon an
attempted construction of the second clause of the third section
of the fourth article of the Constitution, which declares that
"Congress shall have power to dispose of and to make all needful
rules and regulations respecting the territory and other property
belonging to the United States."
 
     In the discussions in both houses of Congress, at the time
of adopting this eighth section of the act of 1820, great weight
was given to the peculiar language of this clause, viz: territory
and other property belonging to the United States, as going to
show that the power of disposing of and regulating, thereby
vested in Congress, was restricted to a proprietary interest in
the territory or land comprised therein, and did not extend to
the personal or political rights of citizens or settlers,
inasmuch as this phrase in the Constitution, "territory or other
property," identified territory with property, and inasmuch as
citizens or persons could not be property, and especially were
not property belonging to the United States. And upon every
principle of reason or necessity, this power to dispose of and to
regulate the territory of the nation could be designed to extend
no farther than to its preservation and appropriation to the uses
of those to whom it belonged, viz: the nation. Scarcely anything
more illogical or extravagant can be imagined than the attempt to
deduce from this provision in the Constitution a power to destroy
or in any wise to impair the civil and political rights of the
citizens of the United States, and much more so the power to
establish inequalities amongst those citizens by creating
privileges in one class of those citizens, and by the
disfranchisement of other portions or classes, by degrading them
from the position they previously occupied.
 
     There can exist no rational or natural connection or
affinity between a pretension like this and the power vested by
the Constitution in Congress with regard to the Territories; on
the contrary, there is an absolute incongruity between them.
 
     But whatever the power vested in Congress, and whatever the
precise subject to which that power extended, it is clear that
the power related to a subject appertaining to the United States,
and one to be disposed of and regulated for the benefit and under
the authority of the United States. Congress was made simply the
agent or trustee for the United States, and could not, without a
breach of trust and a fraud, appropriate the subject of the trust
to any other beneficiary or cestui que trust than the United
States, or to the people of the United States, upon equal
grounds, legal or equitable. Congress could not appropriate that
subject to any one class or portion of the people, to the
exclusion of others, politically and constitutionally equals; but
every citizen would, if any one could claim it, have the like
rights of purchase, settlement, occupation, or any other right,
in the national territory.
 
     Nothing can be more conclusive to show the equality of this
with every other right in all the citizens of the United States,
and the iniquity and absurdity of the pretension to exclude or to
disfranchise a portion of them because they are the owners of
slaves, than the fact that the same instrument, which imparts to
Congress its very existence and its every function, guaranties to
the slaveholder the title to his property, and gives him the
right to its reclamation throughout the entire extent of the
nation; and, farther, that the only private property which the
Constitution has specifically recognized, and has imposed it as a
direct obligation both on the States and the Federal Government
to protect and enforce, is the property of the master in his
slave; no other right of property is placed by the Constitution
upon the same high ground, nor shielded by a similar guaranty.
 
     Can there be imputed to the sages and patriots by whom the
Constitution was framed, or can there be detected in the text of
that Constitution, or in any rational construction or implication
deducible therefrom, a contradiction so palpable as would exist
between a pledge to the slaveholder of an equality with his
fellow-citizens, and of the formal and solemn assurance for the
security and enjoyment of his property, and a warrant given, as
it were uno flatu, to another, to rob him of that property, or to
subject him to proscription and disfranchisement for possessing
or for endeavoring to retain it? The injustice and extravagance
necessarily implied in a supposition like this, cannot be
nationally imputed to the patriotic or the honest, or to those
who were merely sane.
 
     A conclusion in favor of the prohibitory power in Congress,
as asserted in the eighth section of the act of 1820, has been
attempted, as deducible from the precedent of the ordinance of
the convention of 1787, concerning the cession by Virginia of the
territory northwest of the Ohio; the provision in which
ordinance, relative to slavery, it has been attempted to impose
upon other and subsequently-acquired territory.
 
     The first circumstance which, in the consideration of this
provision, impresses itself upon my mind, is its utter futility
and want of authority. This court has, in repeated instances,
ruled, that whatever may have been the force accorded to this
ordinance of 1787 at the period of its enactment, its authority
and effect ceased, and yielded to the paramount authority of the
Constitution, from the period of the adoption of the latter. Such
is the principle ruled in the cases of Pollard's Lessee v. Hagan,
(3 How., 212,) Parmoli v. The First Municipality of New Orleans,
(3 How., 589,) Strader v. Graham, (16 How., 82.) But apart from
the superior control of the Constitution, and anterior to the
adoption of that instrument, it is obvious that the inhibition in
question never had and never could have any legitimate and
binding force. We may seek in vain for any power in the
convention, either to require or to accept a condition or
restriction upon the cession like that insisted on; a condition
inconsistent with, and destructive of, the object of the grant.
The cession was, as recommended by the old Congress in 1780, made
originally and completed in terms to the United States, and for
the benefit of the United States, i. e., for the people, all the
people, of the United States. The condition subsequently sought
to be annexed in 1787, (declared, too, to be perpetual and
immutable,) being contradictory to the terms and destructive of
the purposes of the cession, and after the cession was
consummated, and the powers of the ceding party terminated, and
the rights of the grantees, the people of the United States,
vested, must necessarily, so far, have been ab initio void. With
respect to the power of the convention to impose this inhibition,
it seems to be pertinent in this place to recur to the opinion of
one contemporary with the establishment of the Government, and
whose distinguished services in the formation and adoption of our
national charter, point him out as the artifex maximus of our
Federal system. James Madison, in the year 1819, speaking with
reference to the prohibitory power claimed by Congress, then
threatening the very existence of the Union, remarks of the
language of the second clause of the third section of article
fourth of the Constitution, "that it cannot be well extended
beyond a power over the territory as property, and the power to
make provisions really needful or necessary for the government of
settlers, until ripe for admission into the Union."
 
     Again he says, "with respect to what has taken place in the
Northwest territory, it may be observed that the ordinance giving
it its distinctive character on the subject of slaveholding
proceeded from the old Congress, acting with the best intentions,
but under a charter which contains no shadow of the authority
exercised; and it remains to be decided how far the States formed
within that territory, and admitted into the Union, are on a
different footing from its other members as to their legislative
sovereignty. As to the power of admitting new States into the
Federal compact, the questions offering themselves are, whether
Congress can attach conditions, or the new States concur in
conditions, which after admission would abridge or enlarge the
constitutional rights of legislation common to other States;
whether Congress can, by a compact with a new State, take power
either to or from itself, or place the new member above or below
the equal rank and rights possessed by the others; whether all
such stipulations expressed or implied would not be nullities,
and be so pronounced when brought to a practical test. It falls
within the scope of your inquiry to state the fact, that there
was a proposition in the convention to discriminate between the
old and the new States by an article in the Constitution. The
proposition, happily, was rejected. The effect of such a
discrimination is sufficiently evident." [n2]
 
     n2   Letter from James Madison to Robert Walsh,
          November 27th, 1819, on the subject of the
          Missouri Compromise.
 
 
     In support of the ordinance of 1787, there may be adduced
the semblance at least of obligation deducible from compact, the
form of assent or agreement between the grantor and grantee; but
this form or similitude, as is justly remarked by Mr. Madison, is
rendered null by the absence of power or authority in the
contracting parties, and by the more intrinsic and essential
defect of incompatibility with the rights and avowed purposes of
those parties, and with their relative duties and obligations to
others. If, then, with the attendant formalities of assent or
compact, the restrictive power claimed was void as to the
immediate subject of the ordinance, how much more unfounded must
be the pretension to such a power as derived from that source,
(viz: the ordinance of 1787,) with respect to territory acquired
by purchase or conquest under the supreme authority of the
Constitution -- territory not the subject of mere donation, but
obtained in the name of all, by the combined efforts and
resources of all, and with no condition annexed or pretended.
 
     In conclusion, my opinion is, that the decision of the
Circuit Court, upon the law arising upon the several pleas in
bar, is correct, but that it is erroneous in having sustained the
demurrer to the plea in abatement of the jurisdiction; that for
this error the decision of the Circuit Court should be reversed,
and the cause remanded to that court, with instructions to abate
the action, for the reason set forth and pleaded in the plea in
abatement.
 
     In the aforegoing examination of this cause, the
circumstance that the questions involved therein had been
previously adjudged between these parties by the court of the
State of Missouri, has not been adverted to; for although it has
been ruled by this court, that in instances of concurrent
jurisdiction, the court first obtaining possession or cognizance
of the controversy should retain and decide it, yet, as in this
case there had been no plea, either of a former judgment or of
autre action pendent, it was thought that the fact of a prior
decision, however conclusive it might have been if regularly
pleaded, could not be incidentally taken into view.
