Bouvier's Law Dictionary, Revised 6th Ed (1856):

REDHIBITION, civil law, and in Louisiana. The avoidance of a sale on account
of some vice or defect in the thing sold, which renders it absolutely
useless, or its use so inconvenient and imperfect, that it must be supposed
that the buyer would not have purchased it, had he known of the vice. Civ.
Code of Lo. 2496. Redhibition is also the name of an action which the
purchaser of a defective movable thing may bring to cause the sale to be
annulled, and to recover the price he has paid for it. Vide Dig. 21, 1.
     2. The rule of caveat emptor, (q.v.) in the common law, places a
purchaser in a different position from his situation under the like
circumstances under the civil law; unless there is an express warranty, he
can seldom annul a sale or recover damages on account of a defect in the
thing sold. Chitty, Contr. 133, et seq.; Sugd. Vend. 222 2 Kent, Com. 374;
