[PAULUS libro quarto decimo ad Sabinum. ] §1.1.11.prIus pluribus modis dicitur: uno modo, cum id quod semper aequum ac bonum est ius dicitur, ut est ius naturale.
[PAULUS in the fourteenth book on Sabinus.] "Ius" is used in several senses: in one sense, when that which is always equitable and good is called "ius", as is natural law; in another sense, what is useful to all or to most in any city, as is civil law.
altero modo, quod omnibus aut pluribus in quaque ciuitate utile est, ut est ius ciuile. nec minus ius recte appellatur in ciuitate nostra ius honorarium.
No less is the honorary law rightly called "ius" in our city.
praetor quoque ius reddere dicitur etiam cum inique decernit, relatione scilicet facta non ad id quod ita praetor fecit, sed ad illud quod praetorem facere conuenit.
The praetor also is said to "render justice" even when he decrees unjustly, reference being made, of course, not to what the praetor actually did in that way, but to what it was fitting for the praetor to do.
alia significatione ius dicitur locus in quo ius redditur, appellatione collata ab eo quod fit in eo ubi fit.
In another signification, "ius" is used to denote the place where justice is administered, the name being transferred from that which is done therein to the place where it is done.
quem locum determinare hoc modo possumus: ubicumque praetor salua maiestate imperii sui saluoque more maiorum ius dicere constituit, is locus recte ius appellatur.
Which place we can define in this manner: wherever the praetor, preserving the majesty of his authority and preserving the custom of the ancestors, determines to declare the law, that place is rightly called "ius".
