[IDEM libro quinto ad Quintum Mucium. ] §50.16.120.prUerbis legis duodecim tabularum his 'uti legassit suae rei, ita ius esto' latissima potestas tributa uidetur et heredis instituendi et legata et libertates dandi, tutelas quoque constituendi.
[THE SAME, in the fifth book on Quintus Mucius.] By these words of the Law of the Twelve Tables, "as he has bequeathed concerning his property, so let it be law," a very wide power seems to have been granted both of instituting an heir, and of giving legacies and freedom, and also of appointing guardians.
sed id interpretatione coangustatum est uel legum uel auctoritate iura constituentium.
But this has been narrowed by interpretation, either of the laws, or by the authority of those who establish the law.
