[SCAEUOLA libro quarto quaestionum. ] §13.1.18.prQuoniam furtum fit, cum quis indebitos nummos sciens acceperit, uidendum, si procurator suos nummos soluat, an ipsi furtum fiat.
[SCAEVOLA, Questions, Book IV] Since theft occurs when someone knowingly receives money that is not owed, it must be considered whether, if a procurator pays his own money, theft is committed against him himself.
et Pomponius epistularum libro octauo ipsum condicere ait ex causa furtiua: sed et me condicere, si ratum habeam quod indebitum datum sit.
And Pomponius, in the eighth book of his Letters, says that he himself can bring a condictio on the ground of theft; but that I also can bring a condictio, if I ratify that which was given when not owed.
sed altera condictione altera tollitur.
But by one condictio, the other is extinguished.
