(1) In cases of a sale between merchants, the buyer shall, upon receipt of the subject matter, inspect it without delay, and immediately give a notice thereof to the seller if any defect or deficiency in numbers is found therein; otherwise, he/she has no right to rescind the contract, to demand price cuts or to claim damages thereby. The same shall apply in cases where, within six months, the buyer discovers in the subject matter of the sale a defect which was not immediately discoverable.
(2) The provisions of the preceding paragraph shall not apply to a seller acting in bad faith.
