§ 2-608. Revocation of acceptance in whole or in part.
A. The buyer may revoke his acceptance of a lot or commercial unit whose nonconformity substantially impairs its value to him if he has accepted it:
1. On the reasonable assumption that its nonconformity would be cured and it has not been seasonably cured; or
2. Without discovery of such nonconformity if his acceptance was reasonably induced either by the difficulty of discovery before acceptance or by the seller’s assurances.
B. Revocation of acceptance must occur within a reasonable time after the buyer discovers or should have discovered the ground for it and before any substantial change in condition of the goods which is not caused by their own defects. It is not effective until the buyer notifies the seller of it.
C. A buyer who so revokes has the same rights and duties with regard to the goods involved as if he had rejected them.
D. If a buyer uses the goods after a rightful rejection or justifiable revocation of acceptance, the following rules apply:
1. Any use by the buyer that is unreasonable under the circumstances is wrongful as against the seller and is an acceptance only if ratified by the seller.
2. Any use of the goods that is reasonable under the circumstances is not wrongful as against the seller and is not an acceptance, but in an appropriate case the buyer is obligated to the seller for the value of the use to the buyer. ONCA 13-23, eff. Sept. 24, 2013.
