[PAULUS libro quinto quaestionum. ] §21.2.70.prEuicta re ex empto actio non ad pretium dumtaxat recipiendum, sed ad id quod interest compe||tit: ergo et, si minor esse coepit, damnum emptoris erit.
[SCAEVOLA, Book 5 of Questions.] When a thing has been evicted, the action on purchase is available not merely to recover the price, but for the buyer's interest: therefore also, if it has begun to be less, it will be the buyer's loss.
