45. Paulus. On Sabinus, Book X
parties commit damage because they could not otherwise protect
themselves, they are guiltless; for all laws and all legal systems permit
persons to repel force by force. Qui
cum aliter tueri se possent, damni culpam dederint, innoxii sunt:
vim enim vi defendere omnes leges
omnia iura permittunt.
Lex Aquilia Dig. 9.2
4. Gaius, On the Provincial Edict, Book VII.
Therefore, if I kill your slave who is a thief and is attacking me at the time, I shall be free from liability, "For natural reason permits a man to protect himself from danger". Itaque si servum tuum latronem insidiantem mihi occidero, securus ero: nam adversus periculum naturalis ratio permittit se defendere.
