Roman Law
Some general rules of Roman law / procedures:
Book I. Of Persons
I. Justice and Law.
JUSTICE is the constant and perpetual wish to render every one his due.
1. Jurisprudence is the knowledge of things divine and human; the science of the just and the unjust.
3. The maxims of law are these: to live honesty, to hurt no one, to give every one his due.
II. Natural, Common, and Civil Law.
The law of nature is that law which nature teaches to all animals. For this law does not belong exclusively to the human race, but belongs to all animals, whether of the earth, the air, or the water. Hence comes the union of the male and female, which we term matrimony; hence the procreation and bringing up of children. We see, indeed, that all the other animals besides men are considered as having knowledge of this law.
1. Civil law is thus distinguished from the law of nations. Every community governed by laws and customs uses partly its own law, partly laws common to all mankind. The law which a people makes for its own government belongs exclusively to that state and is called the civil law, as being the law of the particular state. But the law which natural reason appoints for all mankind obtains equally among all nations, because all nations make use of it. The people of Rome, then, are governed partly by their own laws, and partly by the laws which are common to all mankind. We will take notice of this distinction as occasion may arise.
2. The law of the nations is common to all mankind, for nations have established certain laws, as occasion and the necessities of human life required. Wars arose, and in their train followed captivity and then slavery, which is contrary to the law of nature; for by that law all men are originally born free. Further, by the law of nations almost all contracts were at first introduced, as, for instance, buying and selling, letting and hiring, partnership, deposits, loans returnable in kind, and very many others.
3. Our law is written and unwritten, just as among the Greeks some of their laws were written and others were not written. The written part consists of leges (lex), plebiscita, senatusconsulta, constitutiones of emperors, edicta of magistrates, and responsa of jurisprudents [i.e., jurists].
9. The unwritten law is that which usage has established; for ancient customs, being sanctioned by the consent of those who adopt them, are like laws.
11. The laws of nature, which all nations observe alike, being established by a divine providence, remain ever fixed and immutable. But the laws which every state has enacted, undergo frequent changes, either by the tacit consent of the people, or by a new law being subsequently passed.
III. The Law of Persons.
All our law relates either to persons, or to things, or to actions. Let us first speak of persons; as it is of little purpose to know the law, if we do not know the persons for whose sake the law was made. The chief division in the rights of persons is this: men are all either free or slaves.
1. Liberty is the natural power of doing what we each please, unless prevented by force or by law.
2. Slavery is an institution of the law of nations, by which one man is made the property of another, contrary to natural right.
IX. The Power of Parents.
Our children, begotten in lawful marriage, are in our power.
1. Marriage, or matrimony, is a binding together of a man and woman to live in an indivisible union.
2. The power which we have over our children is peculiar to the citizens of Rome; for no other people have a power over their children, such as we have over ours.
3. The child born to you and your wife is in your power. And so is the child born to your son of his wife, that is, your grandson or granddaughter; so are your great-grandchildren, and allyour other descendants. But a child born of your daughter is not in your power, but in the power of its own father.
Book II. Of Things.
I. Divisions of Things.
In the preceding book we have treated of the law of persons. Let us now speak of things, which either are in our patrimony, or not in our patrimony. For some things by the law of nature are common to all; some are public; some belong to corporate bodies, and some belong to no one. Most things are the property of individuals who acquire them in different ways, as will appear hereafter.
1. By the law of nature these things are common to mankind---the air, running water, the sea, and consequently the shores of the sea. No one, therefore, is forbidden to approach the seashore, provided that he respects habitations, monuments, and buildings which are not, like the sea, subject only to the law of nations.
2. All rivers and ports are public; hence the right of fishing in a port, or in rivers, is common to all men.
6. Among things belonging to a corporate body, not to individuals, are, for instance, buildings in cities, theaters, race-courses, and other similar places belonging in common to a whole city.
7. Things sacred, religious, and holy belong to no one; for that which is subject to divine law is not the property of any one.
10. Holy things also, as the walls and gates of a city, are to a certain degree subject to divine law, and therefore are not part of the property of any one. The walls of a city are said to be holy, inasmuch as any offence against them is punished capitally; so, too, those parts of laws by which punishments are established against transgressors, we term sanctions.
XIV. Other Ways of Contracting an Obligation.
An obligation may be contracted by the thing, as, for example, by giving a mutuum. This always consists of things which may be weighed, numbered, or measured, as wine, oil, corn, coin brass, silver, or gold. In giving these things by number, measure or weight, we do so that they may become the property of those who receive them. The identical things lent are returned, but only others of the same nature and quality; and hence the term mutuum, because what I give from being mine becomes yours. From this contract arises the actio termed condictio.
1. Theft is the fraudulent dealing with a thing itself, with its use, or its possession; an act which is prohibited by natural law.
6. It is theft, not only when anyone takes away a thing belonging to another, in order to appropriate it, but generally when anyone deals with the property of another contrary to the wishes of its owner.
Lex Aquileia
2. To kill wrongfully is to kill without any right: consequently, a person who kills a thief is not liable to this actio, that is, if he could not otherwise avoid the danger with which he was threatened.
3. Nor is a person made liable by this law who has killed by accident, provided there is no fault on his part, for this law punishes fault as well as wilful wrong-doing.
4. Consequently, if anyone playing or practicing with a javelin pierces with it your slave as he goes by, there is a distinction made; if the accident befalls a soldier while in the camp, or other places appropriated to military exercises, there is no fault in the soldier, but there would be in anyone else besides a soldier, and the soldier himself would be in fault if he inflicted such an injury in any other place than one appropriated to military exercises.
