[IDEM libro XV digestorum. ] §1.3.12.prNon possunt omnes articuli singillatim aut legibus aut senatus consultis compraehendi: sed cum in aliqua causa sententia eorum manifesta est, is qui iurisdictioni praeest ad similia procedere atque ita ius dicere debet.
[THE SAME on the Digest, Book XV] It is impossible for all individual cases to be comprehended singly either by laws or by decrees of the senate; but when in any case their intention is clear, he who presides over the jurisdiction ought to proceed to similar cases and thus declare the law.
