[ULPIANUS libro singulari pandectarum. ] §12.1.24.prSi quis certum stipulatus fuerit, ex stipulatu actionem non habet, sed illa condicticia actione id persequi debet, per quam certum petitur.
[ULPIANUS from the single book of the Pandects.] If anyone has stipulated for a certain thing, he does not have an action on the stipulation, but he must pursue it by that action for recovery by which a certain thing is claimed.
