(810 ILCS 5/2A-517) (from Ch. 26, par. 2A-517)

Sec. 2A-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 rights and
duties with regard to the goods involved as if the lessee had
rejected them.
