Institutio Oratoria

Again, the point of law is either admitted by both parties or disputed. If it be admitted, the questions which are raised will as a rule be such as the following. Which of the two laws is the most stringent? Does it concern gods or men, the state or private individuals, reward or punishment, great things or small? Does it permit, forbid or command?

Another common question is which of the two laws is the oldest; but the most important question is which of the two laws will suffer less by its contravention, as for example in the case of the hero and the deserter just mentioned, in which case, if the deserter is not put to death, the whole law is ignored, whereas, if he be put to death, the hero will still have another choice left open to him. It is, however, of the utmost importance to consider which course is best from the point of view of morality and justice, a problem for the solution of which no general rules can be laid down, as it will depend on the special circumstances of the case.

If, on the other hand, the point of law is disputed, either one party or both in turn will argue the point. Take the following case as an example.

A father shall be empowered to arrest his son, and a patron to arrest his freedman. Freedmen shall be transferred to their patron's heir. A certain man appointed the son of a freedman as his heir. The son of the freedman and the freedman himself both claim the right to arrest the other.

Laws containing two provisions may conflict with themselves in exactly the same way as two laws may conflict. The following will serve as an illustration.

The bastard born before a legitimate son shall rank as legitimate, the bastard born after the legitimate son shall only rank as a citizen.
