Mr. Justioe Field,
after stating the case, • delivered the opinion of the court.
The complainants are both citizens of France. The fact that one of them was born in Pekin, China, does not change his citizenship. His father was a Frenchman, and by the law of France a child of a Frenchman, though born in a foreign country, retains the citizenship of his father. In this case, also, his father was engaged, at the time of the son's birth, in the diplomatic service of France, being its minister plenipotentiary to China, and by public law the children of ambassadors and ministers accredited .to another country retain the citizenship of their father.
The question presented for solution, therefore, is whether the complainants, being citizens and residents of France, inherit-an interest in the real estate in the District" of "Columbia of which their uncle, a'citizen of the United States and a resident of the District-, died seized. In more general terms the question is: can citizens of France take land in the District of Columbia by descent from citizens of the United States ?
The complainants contend that they inherit an estate in the property described, by force of the stipulation of article 7 of the convention between the United States and France, concluded February 23, 1853, and the provisions of the act of Congress of March 3, 1887, to restrict the ownership of real estate in the Territories to American citizens. Before consid ering the effect of this article .and of the act of 1887, a brief reference will be had to the law's of Maryland in force on. the 27th of February, 1801, which were on that day declared by act of- Congress to be' in force in the District of Columbia. The language of the act is " that the laws of the State of Maryland as they now exist shall be and continue in force in that part of the said District which was ceded by that State to the United States, and by them accepted." 2 Stat. 103, c. 15, § 1.
A part of these laws was the common law, and two acts of Maryland, one passed in March, 1780, " to declare and ascertain the privileges .of the subjects of France" within that State; the Other, passed December 19, 1791, to ratify her cession ' to the United States, entitled " An Act concerning- the Territory of Columbia and the City of Washington." The. common law, unmodified by statute or treaty, would have excluded aliens from inheriting lands in the United States from a' citizen thereof. Its. doctrine is that aliens have no inheritable blood through which a title can be transferred by operation of law. The act of Maryland of 1780 modified that law so far as to allow a subject of France who had settled in that State, and given assurances of allegiance and attachment, to it as required of citizens, to devise to French subjects, who for that purpose were to be deemed citizens of the State. Act of March, 1780, c. 8, § 5, 1 Dorsey's Laws of Maryland, 158. It also provided that if the decedent died intestate his natural kindred, whether residing in France or elsewhere, should inherit his real estate in like-manner as if such decedent ancl his kindred were citizens of the United States. It had A of bearing, however, upon the inheritance of a subject of France, except from a Frenchman domiciled in the State. The act of Maryland of December 19, 1791, which provided in-its sixth section that any foreigner might, by deed or will thereafter. made, take and hold lands within the State .in the_ same, manner as if he were a citizen thereof, and that the lands might bé' conveyed by him, and transmitted to and inherited, by his heirs and relations as if he and they were citizens' qf the State, did not do away with the disability of foreigner to take real property within that State by inheritance from a citizen of the United States. It was so held in effect in Spratt v. Spratt, 1 Pet. 343 S. C. 4 Pet. 393.
On the 30th of September, 1800, a convention of peace, commerce and navigation was concluded between France and the Unitéd States, the 7th article of which provided that "the citizens and inhabitants of the United States shall be at liberty to dispose by testament, donation or otherwise, of their goods, movable and immovable, holden in the territory of the French Republic in Europe, and the citizens of the French Republic shall have the same liberty with regard to goods movable and immovable, holden in the territory of the United ' States, in favor of such persons as. they shall think proper. The citizens and inhabitants of either of the two countries, who shall be heirs of goods, movable or immovable, in the other, shall be able to succeed ab intestato, without being obliged to obtain letters of naturalization, and without having the effect of this provision contested or impeded under any pretext whatever." 8 Stat. 182.
This article, by its terms, suspended, during the existence of the treaty, the provisions of the common law of Maryland and of the statutes of that State of 1780 and of 1791, so far as they prevented citizens of France from taking by inheritance from citizens of the United States, property, real or personal, situated therein.
That the treaty power of the United States extends to all proper subjects of negotiation between our government and the governments of other nations, is clear. It is also clear that the protection which should be afforded to the citizens of one country owning property in another, and the manner in which that property may be transferred, devised or inherited, are fitting subjects for such negotiation and of regulation by mutual stipulations between the two countries. As commer-. cial intercourse increases between different countries the residence of citizens of one country within the territory of the other naturally follows, and the removal of their disability from alienage to hold, transfer .and inherit property in such cases tends to promote amicable relations. Such removal has .been within the present century the frequént subject of treaty arrangement. The treaty power, as expressed in the Constitution, is in terms unlimited except by those restraints which are found in that instrument against the action of the government or of its departments, and those, arising from the nature of the government itself and of that-of the States. It would not be contended that it extends so far' as to authorize what the Constitution forbids, or a change in /the character of the government or' in that of one of the States, or a cession of any portion of the territory of. the latter, without its - consent. Fort Leavenworth Railroad Co. v. Lowe, 114 U. S. 525, 541. But with these exceptions, it is not perceived that there is any limit to the questions which can be adjusted touching any matter which is properly the ^subject of negotiation with a foreign country. Ware v. Hylton, 3 Dall. 199; Chirac v. Chirac, 2 Wheat. 259; Hauenstein v. Lynham, 100 U. S. 483; 8 Opinions Attys. Gen. 417; The People v. Gerke, 5 California, 381.
Article 7 of the convention of 1800 was in force when-the act of Congress adopting the laws of Maryland, February. 27, 1801, was passed, f That law adopted and continued in force the law of Maryland' as it then existed. It- did not adopt the law of Maryland as it existed previous ]to the treaty; for that would have been in effect to, repeal the treaty-so .far as the District of Columbia was affected. In adopting it as it-then existed, it adopted the law with its provisions suspended during the continuance of the treaty so far as they conflicted with it — in other words, the;treaty, being part of the.supreme'. law of the-land, controlled the statute and common law'of Maryland whenever it differed from them. The treaty expired by its own limitation in eight years, pursuant-to an article in- , serted by the Senate. 8 Stat. 192. During its continuance-citizens of France could take property in the District of Colum: bia. by inheritance from citizens of the United. States. But after its expiration that right was limited as provided by the statute and common law of Maryland, as adopted by Congress oh the 27th of February, 1801, until the convention between the United States and France was concluded, February 23, 1853; TJie- .7th, article-'of that .convention is. as follows:
"In all the States of the Union, whose existing laws per'mjt'it, so long and' to the same extent as the said laws shall remain in force, Frenchmen shall'enjoy the right of possessing personal and real property by the same title and in the same, manner as the citizens of the United States. They shall be free to dispose of it as they may please, either gratuitously or fpr value received, by donation, testament, or-otherwise, just as those citizens themselves; and in no case shall they be •subjected to taxes on transfer, inheritance, or any others different -from those paid by the latter, or to taxes which shall not be equally imposed.
' ' " As to the States of- the Union, by whose existing laws aliens are not permitted to hold real estate, the President engages to recommend' to them the passage of Such laws as may be'necessary for the purpose of conferring this right.
" In like manner, but with the reservation of the ulterior right of establishing reciprocity in regard to possession and inheritance, the government of Prance accords to the citizens of the United States the same rights within its territory in respect to real and personal property, and to inheritance, as are enjoyed there by its own citizens." 10 Stat. 996.
This article is not happily drawn. It leaves in doubt what is meant by " States of the Union." Ordinarily these terms would be held to apply to those political communities exercising various attributes of sovereignty which compose the United States, as distinguished from the organized municipalities known as Territories and the District of Columbia. And yet.separate cotnjnunities, with an independent local government, are often described as states, though the extent of their political sovereignty be limited by relations to a more general government or to other countries. Halleck on Int. Law, c. 3, § 5, 6, 7. The term is used in general jurisprudence and by writers on public law as denoting organized political societies with an established government. Within this definition the District of Columbia, under the government of the United States,, is as much a State as any of those political communi- . ties which compose the United States. Were there no other •territory under the government of the United States, it would not be questioned that the District of Columbia would be a State within the meaning of international law; and it is not perceived that' it is any less a State within that meaning because other States and other territory are also under the same government. In Hepburn v. Ellzey, 2 Cranch, 445, 452, the question arose whether a resident and a citizen of the District of Columbia could sue a citizen of Virginia in the Circuit Court of the United States. The court, by Chief Justice Marshall, in deciding the question, conceded that the District of. Columbia was a distinct, political society, and therefore a State according to the definition of writers on general law; but held, that the act of Congress in providing for controversies between citizens' of different States in the Circuit Courts, referred to that term as used in the Constitution, and therefore 'to'one of the States composing the United States. A similar concession, that the District of Columbia, being a separate political community, is, in a certain sense, a State, is made by this court in the recent case of Metropolitan Railroad Co. v. District of Columbia, 132 U. S. 1, 9, decided at the present term.
Aside from the question in which of .these significations the terms are used in the convention of 1853, we think' the construction of article 7 is free from difficulty: In some States aliens were permitted to hold 'real estate, but not to take by inheritance. \ To this right to hold real estate in some States reference is had by the words " permit' it in the first clause, and it is alluded to in the second clause as not permitted in others. This will be manifest if we read the second clause before the first. This construction, as well' observed by coun-sel,'gives consistency and harmony to all the provisions of the article, and comports with its character" as- an agreement. intended to confer reciprocal -rights on the citizens of each country with respect .to property held by them within the territory of the other. To construe the first clause as providing, that Frenchmen shall enjoy the right of possessing personal and real property by the same title and in the same manner as citizens of the United States, in States, so long as their -laws ' permit such enjoyment, is to give a meaning to the article by which nothing is conferred not already possessed, and leaves no adequate reason for the concession by France of rights to citizens of the United States, made in the third clause. We do not think this construction admissible. It' is a rule, in 'cónstruing treaties as well as laws, to give a sensible' meaning to' all their provisions if that be practicable. " The interpretation, therefore," says Yattel, "which would render a treaty null and inefficient cannot he admitted; " and again, " it ought to be interpreted in such a manner as that it may have its effect, and not prove vain and nugatory." Vattel, Book II, c. 17. As we read the article it declares that in all the States' of the Union' by whose laws aliens are permitted to hold real estate, so long as such laws remain in force, Frenchmen shall enjoy the right of possessing personal and real property by the same title and in the .same manner as citizens of the United States. They shall be free to dispose of it as'they may please — :by donation, testament, or otherwise — ^ just as those citizens themselves. But as to the. States by whose existing laws' aliens are- not permitted to hold real estate, the treaty engages that the' President- shall recommend to them the passage-of such laws as may-be necessary for the purpose .of conferring that right..
In determining the question in what sense the terms " States ;of.the Union" are used, it is to be borne in .mind that the laws of the District and of some of the Territories, existing at the -time the convention was concluded' in 1853,- allowed aliens'to hold' real estate. If, therefore, these terms are held to exclude those political communities, our government is placed in a very inconsistent position — stipulating that citizens of France shall enjoy the right Of holding, disposing of, and inheriting, -in like .manner as citizens of the United States, property, real and personal, in those States whose laws, permit, aliens to hold "real estate; that is, that in those States citizens of France, in holding; disposing of, and inheriting property, shall be. free from the disability of alienage; and, in order that they may in like manner be free from such disability in those States whose existing laws do not permit aliens to hold real estate, engaging that the President shall recommend the passage of laws conferring that right; while, at the same time, refusing to citizens of France holding property in the District and in some of the Territories, where the power'of the United States is in that respect unlimited, a like release from the disability of alienage, thus discriminating against them in favor of citizens of France holding property in States having similar legislation. No plausible motive can be assigned for such discrimination. A right which the government of the United States apparently desires that citizens of France should enjoy in all the States, it would hardly refuse to them in the District embracing its capital, or in any of its own territorial dependencies. By the last clause of the article the government of France accords to the citizens of the United States the. same rights within its territory in respect to real and personal property and to inheritance as' are enjoyed there by its own citizens. There is no limitation as to the territory of France in which the right of inheritance is conceded. And it declares that this right is given in like manner as the right is given by the government of the United States to citizens of France. To ensure reciprocity in the terms of the treaty, it would be necessary to hold that by " States of the Union " is meant all the political communities exercising legislative powers in the country, embracing not only those political communities which constitute the United States, but also those communities which constitute thé political bodies known as Territories and the District of Columbia. It is, a general principle of construction with respect to treaties that they shall be liberally construed, so as to carry out the, apparent intention of the parties to secure equality and reciprocity between them. As they are contracts between independent nations, in their construction words are to be taken in their ordinary meaning, as understood in the public law of nations, and not in any artificial or special sense impressed upon them by local law, unless such restricted sense is clearly intended. And it has been held by this court that where a treaty admits of two constructions, One restrictive of rights that may "be claimed under it and the other favorable to them, the latter is to be preferred. Hauenstein v. Lynham, 100 U. S. 483, 487. The stipulation that the government of .France in like.manner accords to the citizens of the United • States the same rights within its territory in respect to real and personal property and inheritance as are enjoyed there by its own citizens, indicates that' that government considered that similar rights were extended to its citizens within the territory of the United States, whatever the designation given to théir different political communities.
'We are, therefore, of opinion that this is the meaning of the ' article in question — that there shall be reciprocity in respect to the acquisition and inheritance of property in one country by the-citizens of the other, that is, in all political communities in the United States where legislation permits aliens to hold real estate, the disability of Frenchmen from alienage in disposing and inheriting property, real and personal, is removed, and the, same right, of disposition and inheritance of property, in France, is accorded to citizens' of the United States, as are there enjoyed by its own citizens. This construction, finds support' in the first.section of the act of March 3d, 1887. 24 Stat. 476, c. 340. That section declares that it shall be unlawful for any person or persons not citizens of the United States, or who have not declared their intention to become citizens, to thereafter acquire, hold or own real estate, or any interest therein, in any of the Territories of the United States or in the' District of Columbia,,except such as may be acquired by inheritance or in good faith in the ordinary course -of justice in the collection of debt's previously created. There is here a plain implication that property in the District of Columbia and in the Territories may be acquired by aliens ' by inheritance under existing laws'; and no property could be acquired by them in the District by inheritance except, by virtue of the law of Maryland as it- existed when adopted by the United States during the existence of the convention of 1800 or under the 7th article of- the convention of 1853. Our' conclusion is, that- the complainants are entitled to take by inheritance an interest in the real property in the District of Columbia of-which their uncle died seized. The decree of the court below will, therefore, be
Reversed and the cause remanded, with direction to overrule the demurrer of the defenda/nts; and it is so ordered.
