Sententia quae in rem iudicatam transit, pro veritate habetur - When a definitive sentence is declared, it is considered to be the truth. In the case of a sentence in rem iudicatam (that finally consents to consider a judgement completed), its content will then be the only legally relevant consideration of a fact.⏎
Ubi lex voluit, dixit; ubi noluit, tacuit - When the law wanted to regulate the matter in further detail, it did regulate the matter; when it did not want to regulate the matter in further detail, it remained silent (in the interpretation of a law, an excessively expansive interpretation might perhaps go beyond the intention of the legislator, thus we must adhere to what is in the text of the law and draw no material consequences from the law's silence).⏎
Sic utere tuo ut alienum non laedas - "Use your property so as not to injure that of your neighbours." While an individual is entitled to the use and enjoyment of one's estate, the right is not without limits. Restrictions can give rise to tort actions include trespass, negligence, strict liability, and nuisance.[8]⏎
