In a redhibitory action, the buyer demands a full refund or a reduction in the purchase price because the product has a hidden defect (redhibitory defect) that prevents it from performing the task for which it was purchased.
In fact, Louisiana does also have a separate lemon law of its own, which like others applies exclusively to automobiles.
If the buyer can prove that the seller knew of the existence of the defect in the product but sold it anyway, he may be entitled not only to return of the purchase price, but to replacement of any expenses caused by the sale, reasonable attorney fees and damage resulting from use of the defective product.
The judge may also deduct for any satisfactory service the buyer derived from the product before or in spite of the defect.
Today, many sellers require buyers to sign a waiver of warranty at the time of purchase.
