[IDEM libro undecimo ad edictum. ] §18.1.50.prLabeo scribit, si mihi bibliothecam ita uendideris, si decuriones Campani locum mihi uendidissent, in quo eam ponerem, et per me stet, quo minus id a Campanis impetrem, non esse dubitandum, quin praescriptis uerbis agi possit.
[THE SAME, On the Edict, Book XI] Labeo writes that if you sell me a library on the condition that the decurions of Campania sell me a place in which to place it, and it is my fault that I do not obtain this from the Campanians, there is no doubt that an action on the prescribed words can be brought.
ego etiam ex uendito agi posse puto quasi impleta condicione, cum per emptorem stet, quo minus impleatur.
I think that an action on the sale can also be brought, as if the condition had been fulfilled, since the failure of its fulfillment is due to the buyer.
