[IDEM libro quinquagensimo quarto ad edictum. ] §18.1.52.prSenatus censuit, ne quis domum uillamue dirueret, quo plus sibi adquireretur neue quis negotiandi causa eorum quid emeret uenderetue: poena in eum, qui aduersus senatus consultum fecisset, constituta est, ut duplum eius quanti emisset in aerarium inferre cogeretur, in eum uero, qui uendidisset, ut irrita fieret uenditio.
[THE SAME, On the Edict, Book LIV] The Senate decreed that no one should demolish a house or a villa in order that more might be acquired for himself, nor should anyone buy or sell any of them for the sake of trading. A penalty was established against anyone who acted contrary to the decree of the Senate: namely, that he who had bought should be compelled to pay double the purchase price into the treasury, while against him who had sold, that the sale should be rendered void.
plane si mihi pretium solueris, cum tu duplum aerario debeas, repetes a me: quod a mea parte irrita facta est uenditio.
Clearly, if you pay the price to me, although you owe double to the treasury, you will recover it from me, because on my part the sale has been rendered void.
nec solum huic senatus consulto locus erit, si quis suam uillam uel domum, sed et si alienam uendiderit.
And this decree of the Senate will apply not only if someone sells his own villa or house, but also if he sells one belonging to another.
