Ius



Ius or Jus (Latin, plural iura) in ancient Rome was a right to which a citizen (civis) was entitled by virtue of his citizenship (civitas). The iura were specified by laws, so ius sometimes meant law. As one went to the law courts to sue for one's rights, ius also meant justice and the place where justice was sought.

On the whole, the Romans valued their rights as the greatest good of Roman citizenship (civitas romana), as opposed to citizenship in other city-states under the jurisdiction of Rome but without Roman rights. Outsiders (peregrini) and freedmen (libertini) perforce used Roman lawyers to represent them in actions undertaken under the jurisdiction of Roman law. Representation was one of the civic obligations (munera) owed to the state by citizens. These munera (on which account the citizens were municipes) included military service as well as paying taxes, but specialized obligations might also be associated with functions of elected offices or assigned by the government, such as paying the cost of road or aqueduct maintenance. Some of these functions were highly lucrative, such as tax collecting, since the collector collected much more than he owed the government, but for the most part functionaries were appointed for their wealth and were expected to assume the costs as their munus. If they did not, they were tried and sometimes executed. Violation of the iura of other citizens, whether in office or out, was a serious matter, for which the punishment might be death.

Meanings of ius
Ius in ancient Roman law had two principal meanings, which are still reflected in French droit, German Recht, English right and Castilian derecho. Ferdinand Mackeldy, 19th-century jurist, analyzed them into two principles: ius is the law, a set of compulsory rules (Jus est norma agendi, "law is a rule of conduct"), which he called objective or positive law, and a set of possibilities to act (Jus est facultas agendi, "law is a license to act"), which he called subjective law, or duties.

Aequum et bonum
Ius was defined by the jurists Publius Juventius Celsus and Julius Paulus as the aequum et bonum, "the just and the fair", or justice. Jurisprudence was the art of bringing it about through application of the laws; thus ius was law in the abstract, as in the English usage of the term "the law". Iura were "the whole of laws" (iura populi Romani), not a list of all the laws, but the very principle of legality, which might be applied through this law or by the magistrates and lawyers of Rome through disputation in the law courts. Ius might be something less than the whole body of law when special fields were designated by an adjective, such as ius publicum, "public law," as opposed to private law.

The actual laws (leges), or written statutes, were only the specific tools through which ius was applied. Ius was the law in its broadest sense or its ideal state, above and unaffected by the contingent decrees that the state happened to enact—hence the distinction between the English terms justice and legislation.

Jura et potestates


Ius as the law was generally the domain of Roman aristocrats, from whose ranks the magistrates were chosen and who often defended clients in court. On a more practical basis, the populace of Rome daily encountered the primary meaning of ius. They understood that they had rights. Furthermore, these rights could be named and enumerated in formulae beginning with the word ius followed by a descriptive phrase, most often in the genitive case: "the right of ...."

Black defines ius in the sense of a right as "a power, privilege, faculty, or demand inherent in one person and incident upon another." This power, or potestas, was a license governing behavior between persons granted by the constitution. It determined what one citizen or group of citizens could or could not do regarding another; i.e., potestas is to be translated as authority, which the possession of iura gave to individuals. One might act socially sui iuris, on one's own authority, asserting one's own right, or on behalf of another, alieni iuris, in response to a demand to serve his right by being under his authority.

This was the principle binding soldiers in the army: the consul, or a commander of some other rank, had a right to demand public service of citizens in the army, who were then under his authority. The magistrates thus had the right and power to draft men into the army at any time, but this demand was never a private affair; the males were lawfully assembled and selections were made by the commanders of the units. Typically, the right to raise a legion from a given populace for a specified purpose under the Roman Republic had to be granted by a senatus consultum, a decree of the Senate.

Similarly, under the Roman Empire the imperator ("commander") was from a legal point of view the chief magistrate whose major ius was the ordering of all public affairs, for which he could demand assistance from anyone at any time. The cynical demands of the bad emperors and the beneficial ones of the good emperors are described at great length by the historians of the empire, such as Tacitus.

The list below contains iura from different branches of Roman civilization. A ius of ancient Rome, marked by the imperial eagle, typically begins in the Roman Republic and continues through the Roman Empire. A ius of the Holy Roman Empire is marked with the double-headed eagle. The term is used in this article in the general sense to mean also the Carolingian Empire, named after Charlemagne, who had the title Holy Roman Emperor. His domain also included what is now France. Its iura reflect early Germanic laws. They are more likely to be found as legal principles in modern European countries. Iura that originated and remained primarily as canon law are marked with the coat of arms of the Holy See.

C

 * Jus canonicum. Canon law
 * Ius civile. In Roman law, the laws resulting from statutes and decrees governing the citizenry, as elaborated by the commentators of Roman law. According to the distinction employed by Gaius, the ius civile is the law applied only to Roman citizens; the ius gentium governed foreigners or was applied in cases involving both Romans and foreigners.
 * Jus civile. Civil law. The system of law peculiar to one state or people. Inst 1, 2, 1. Particularly, in Roman law, the civil law of the Roman people, as distinguished from the jus gentium. The term is also applied to the body of law called, emphatically, the "civil law."
 * The jus civile and the jus gentium are distinguished as follows. All people ruled by statutes and customs use a law partly peculiar to themselves, partly common to all men. The law each people has settled on for itself is peculiar to the state itself, and is called jus civile, as being peculiar to that very state. The law that has come to be generally accepted among all men—the law that is guarded among all peoples quite alike—is called the jus gentium, "and all nations use it as if it were the law. The Roman people, therefore, use a law that is partly peculiar to itself, partly common to all men." Hunter, Rom. Law, 38.
 * But this is not the only, or even the generally accepted, use of the words. What the Roman jurists had chiefly in view when they spoke of jus civile was not local as opposed to cosmopolitan law, but the old law of the city as contrasted with the newer law introduced by the praetor (jus prœtorium, jus honorarium). Largely, no doubt, the jus gentium corresponds with the jus honorarium: but the correspondence is not perfect. Id. 39.
 * Jus civile est quod sibi populus constituit. "The civil law is what a people establishes for itself". Inst. 1, 2, 1; Jackson v. Jackson, 1 Johns. (N.Y.) 424, 426.

Mackeld. Rom. Law, § 191.

G

 * Jus gentium. The law of nations. That law that natural reason has established among all men and which is equally observed among all nations is called the law of nations, "as being the law that all nations use". Inst 1, 2, 1; Dig. 1, 1, 9; 1 Bl. Comm. 43; 1 Kent, Comm. 7; Mackeld. Rom. Law, § 125.
 * Although this phrase had a meaning in Roman law that may be rendered by our expression "law of nations", it must not be understood as equivalent to what we now call "international law", its scope being much wider. It was originally a system of law, or more properly, equity, gathered by early Roman lawyers and magistrates from the common ingredients in the customs of the old Italian tribes—those being the nations, gentes, whom they had opportunities of observing—to be used in cases where the jus civile did not apply; that is, in cases between foreigners, or between a Roman citizen and a foreigner. The principle upon which they proceeded was that any rule of law common to all the nations they knew of must be intrinsically consonant to right reason, and therefore fundamentally valid and just. From this it was an easy transition to the converse principle, viz., that any rule that instinctively commended itself to their sense of justice and reason must be a part of the jus gentium. And so the latter term came eventually to be synonymous with "equity" (as the Romans understood it.) or the system of praetorian law.
 * Modern jurists frequently employ the term ius gentium privatum to denote private international law, or that subject that is otherwise styled the "conflict of laws"; and ius gentium publicum for public international law, or the system of rules governing the intercourse of nations with each other as persons.
 * Ius gentium. In early Roman law, the law followed by all peoples, closely akin to the ius naturale. From this universal sense it was used more specifically to describe the international law that governed Rome’s relationship with other states. Following the works of Gaius, the term was employed more narrowly to represent the law that applied among foreigners, and among Romans and foreigners. Foreigners, and the legal relations of Romans with them, were governed by the ius gentium.


 * Ius gladii. The right of the sword; the executory power of the law; the right, power, or prerogative of punishing for crime. 4 Bl. Comm. 177.

N
As the Roman jurist Ulpian said, “that which nature has taught all animals”. For most writings of classical Roman law, synonymous with ius naturae. From the writings of Paul, however, the term ius naturale acquired the sense of an ideal of law, quod semper est bonum et aequum—those actions that are always fair and just. This sense is followed in the Thomist conceptions of natural law, or lex naturalis.
 * Ius naturae. Literally, “the law of nature”. In Roman law, a near synonym for ius naturale—a law that is supported by natural reason, and so a law that is, or ought to be, respected by the laws of all nations. Thus, the ius naturae was said to support the ius gentium in its universal sense. However, even this relationship is not always congruent: famously, in the introduction to Justinian's Institutes, slavery is forbidden by nature but allowed by the ius gentium. Even so, there was the general sense, seized on increasingly from Roman writings throughout the Renaissance and early modern age, that civil law was to reflect the obligations of natural law, especially when natural law required freedom.
 * Ius naturale. The natural law, or law of nature; law or legal principles, supposed to be discoverable by the light of nature or abstract reasoning, or to be taught by nature to all nations and men alike; or law supposed to govern men and peoples in a state of nature i.e., in advance of organized governments or enacted laws. This conceit originated with the philosophical jurists of Rome, and was gradually extended until the phrase came to denote a supposed basis or substratum common to all systems of positive law, and hence to be found, in greater or less purity, in the laws of all nations. And, conversely, they held that if any rule or principle of law was observed in common by all peoples with whose systems they were acquainted, it must be a part of the ius naturale, or derived from it. Thus the phrases "ius naturale" and "ius gentium" came to be used interchangeably.
