[PAPIRIUS IUSTUS libro secundo de constitutionibus. ] §50.12.13.prImperatores Antoninus et Uerus Augusti rescripserunt opera exstruere debere eos, qui pro honore polliciti sunt, non pecunias pro his inferre cogi.
[PAPIRIUS IUSTUS, in the second book on Constitutions.] The Emperors Antoninus and Verus, Augusti, replied by rescript that those who have promised a work in return for a public office ought to construct the work, and not be compelled to pay money instead of it.
§50.12.13.1Item rescripserunt condiciones donationibus adpositas, quae in rem publicam fiunt, ita demum ratas esse, si utilitatis publicae interest: quod si damnosae sint, obseruari non debere.
Likewise they replied by rescript that conditions attached to donations made to the state are only valid if it is of public utility; but if they are disadvantageous, they ought not to be observed.
et ideo non obseruandum, quod defunctus certa summa legata uetuit uectigal exerceri.
And therefore, that which the deceased forbade—namely, that a tax be collected—after bequeathing a certain sum, is not to be observed.
esse enim tolerabilia, quae uetus consuetudo comprobat.
For those things are tolerable which ancient custom approves.
