Okla. Stat. tit. 12A, § 12A-2A-517: Revocation of Acceptance of Goods

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 rights and duties with

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