This right becomes subject to judicial determination when the law requires the public custody of the person as the means of vindicating the rights of others. The security of the liberty of the individual and of the rights of others is graduated by the intrinsic equity of the law, in purpose and application. The means of protecting this liberty of the individual without haz- arding the freedom. of others must be sought in the provisions of the remedial and penal law. Independently of forfeiture of personal liberty under such laws and of its limita- tions in the domestic relations, freedom, in this sense, is a status which is invariable under all legal systems. It is the subject of judicial determination when a condition incompatible with the possession of per- sonal liberty is alleged against one who claims freedom as his status. A commun- ity wherein law should be recognized, and wherein nevertheless this status should not be enjoyed by any private person, is incon- ceivable; and, wherever its possession is thus controverted, the judicial question arises of the personal extent of the law which attributes liberty to free persons. The law may attribute it to every natural person, and thereby preclude the recogni- tion of any condition inconsistent with its possession. This universal extent of the law of free condition will operate in the in- ternational as well as in the internal private law of the state. In most Euro- pean countries the right of one, under the law of a foreign country, to control the person of another who by such law had been his slave or bondman is not recog- nized under that international rule for the allowance of the effect of a foreign law which is called comity, because the law of those countries attributes personal liberty as a right to every natural person. 1 Hurd, Law of Freedom §§ 116, 300. In other countries the power of the mas- ter under a foreign law is recognized in specified cases by a statute or treaty, while an otherwise universal attribution of per- sonal liberty precludes every other recog- nition of a condition of bondage. On this principle, in some of the United States, an obligation to render personal service or labor, and the corresponding right of the person to whom it is due, existing under the law of other states, were not enforced except in cases of claim within art. 4, sec. 2,3 of the constitution of the United States; 18 Pick. 193; 20 Ν. Υ. 562. Legal rights are the effects of civil soci- ety. No legal condition is the reservation of a state of nature anterior to civil soci- ety. Freedom, as here understood, is the effect of law, not a pre-existing natural element. It is, therefore, not necessarily attributed to all persons within any one jurisdiction. But personal liberty, even though not attributed universally, may be juridically regarded as a right accordant with the nature of man in society; and the effect of this doctrine will appear in a legal presumption in favor of free condition, which will throw the burden of proof always on him who denies it. This pre- sumption obtained in the law of Rome (XII Tab. T. vi. 5; Dig. lib. 40 tit. 5, 1.53; lib. 43, tit. 29, s. 8, 1. 9; lib. 50, tit. 17, 11. 20, 22) even when slavery was derived from the jus gentium, or that law which was found to be received by the general reason of man- kind; 1 Hurd, Law of Freedom § 157. In English law, this presumption in favor of liberty has always been recognized, not only in the penal and remedial law, but in applying the law of condition, at a time when involuntary servitude was lawful; Fortesque, cc. 42, 47; Co. Litt. fol. 124 b; Wood, Inst. c. 1, §5. In the slave-holding states of the Union, a presumption against the freedom of persons of negro descent arose or was declared by statute; Cooper, Justin. 485; 1 Dev. 336; 8 Ga. 157; 5 Halst. N. J. 275. In interpreting manumission clauses in wills, the rule differed in the states according to their prevailing policy; Cobb, Slav. 298. The condition of a private person who is legally secured in the enjoyment of those rights of action, in social relations, which might be equally enjoyed by all private per- sons. The condition of one who may exercise his natural powers as he wills is not known in jurisprudence, except as the character- istic of those who hold the supreme power of the state. The freedom which one may have by his individual strength resembles this power in kind, and is no part of legal freedom. The legal right of one person involves correlative obligations on others. All persons must be restricted by those obligations which are essential to the free- dom of others; 2 Harr. Cond. La. 208; but these are not inconsistent with the pos- session of rights which may be enjoyed equally by all. Such obligations constitute a condition opposed to freedom only as things which mutually suppose and require each other. Where the law imposes obli- gations incompatible with the possession of such rights as might be equally en- joyed by all, a
