[IDEM libro quinto pandectarum. ] §45.1.103.prLiber homo in stipulatum deduci non potest, quia nec dari oportere intendi nec aestimatio eius praestari potest, non magis quam si quis dari stipulatus fuerit mortuum hominem aut fundum hostium.
[THE SAME, book five of the Pandects] A free man cannot be made the subject of a stipulation, because it can neither be claimed that he ought to be given, nor can his valuation be paid, any more than if someone had stipulated for a dead slave or the land of an enemy to be given.
