Semel malus semper præsumitur esse malus in eodem genere.
A man once bad, is always presumed to be bad, in the same way.
Semper in dubiis benigniora præferenda sunt.
Always in doubtful cases, more favourable things are to be preferred.
Semper in stipulationibus et in cæteris contractibus id sequimur, quod actum est; aut si non pareat, quid actum est, erit consequens ut id sequamur, quod in regione in qua actum est frequentatur. Quid ergo, si neque regionis mos appareat quia varius fuit? ad id quod minimum est, religenda summa est.
Always in bargains, and in other contracts, we follow that which has been done, or if that does not appear which hath been done, the consequence will be that we should follow that which is usual in the country, in which it was performed: what therefore is necessary to be done, if the custom of the country does not appear? either, because it has been various; the sum is to be reduced, to that which is the least.
Semper in obscuris, quod minimum est, sequimur.
In obscure cases we always follow that which is least.
Semper qui non prohibet pro se intervenire, mandare creditur, sed et si quis ratum habuerit, quod gestum est, obstringitur mandati actione.
He who does not prohibit one to interfere for himself, is always believed to order him; but if any one shall confirm what hath been done, he is bound by the action of his mandate.
