[POMPONIUS libro septimo decimo ad Sabinum. ] §26.8.4.prEtsi pluribus datis tutoribus unius auctoritas sufficiat, tamen si tutor auctoretur, cui administratio tutelae concessa non est, id ratum a praetore haberi non debet.
[POMPONIUS, in the seventeenth book of his Commentary on Sabinus.] Even if the authority of one guardian is sufficient when several have been appointed, nevertheless, if a guardian to whom the administration of the guardianship has not been granted interposes his authority, this ought not to be held valid by the praetor.
et ideo puto uerius esse, quod Ofilio placebat, si eo tutore auctore, qui tutelam non gerat, emam a pupillo sciens alium eius tutelam gerere, dominum me non posse fieri: item si eo auctore emam, qui a tutela fuerit remotus: nec enim id ratum haberi.
And therefore I think that the opinion which pleased Ofilius is more correct, namely, that if, with that guardian interposing his authority who does not manage the guardianship, I buy from a ward, knowing that another manages his guardianship, I cannot become the owner; likewise if I buy with the authority of one who has been removed from the guardianship, for indeed this is not held valid.
