N.Y. Uniform Commercial Code Law § 2-a-517: Revocation of Acceptance of Goods

Section 2-A-517. Revocation of Acceptance of Goods.

(1) A lessee may revoke acceptance of a lot or commercial unit whose

nonconformity substantially impairs its value to the lessee if the

lessee has accepted it:

(a) except in the case of a finance lease, on the reasonable

assumption that its nonconformity would be cured and it has

not been seasonably cured; or

(b) without discovery of the nonconformity if the lessee's

acceptance was reasonably induced either by the lessor's

assurances or, except in the case of a finance lease, by the

difficulty of discovery before acceptance.

(2) Except in the case of a finance lease that is not a consumer

lease, a lessee may revoke acceptance of a lot or commercial unit if the

lessor defaults under the lease contract and the default substantially

impairs the value of that lot or commercial unit to the lessee.

(3) If the lease agreement so provides, the lessee may revoke

acceptance of a lot or commercial unit because of other defaults by the

lessor.

(4) Revocation of acceptance must occur within a reasonable time after

the lessee discovers or should have discovered the ground for it and

before any substantial change in condition of the goods which is not

caused by the nonconformity. Revocation is not effective until the

lessee notifies the lessor.

(5) A lessee who so revokes has the same right and duties with regard

to the goods involved as if the lessee had rejected them.
