N.Y. Uniform Commercial Code Law § 2-608: Revocation of Acceptance in Whole or in Part

Section 2--608. Revocation of Acceptance in Whole or in Part.

(1) The buyer may revoke his acceptance of a lot or commercial unit

whose non-conformity substantially impairs its value to him if he has

accepted it

(a) on the reasonable assumption that its non-conformity would be

cured and it has not been seasonably cured; or

(b) without discovery of such non-conformity if his acceptance

was reasonably induced either by the difficulty of discovery

before acceptance or by the seller's assurances.

(2) 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.

(3) A buyer who so revokes has the same rights and duties with regard

to the goods involved as if he had rejected them.
