If, after the issue of a listed building enforcement notice, consent is granted under section 8(3)—
for the retention of any work to which the notice relates; or
permitting the retention of works without compliance with some condition subject to which a previous listed building consent was granted,
the notice shall cease to have effect in so far as it requires steps to be taken involving the works not being retained or, as the case may be, for complying with that condition.
The fact that such a notice has wholly or partly ceased to have effect under subsection (1) shall not affect the liability of any person for an offence in respect of a previous failure to comply with that notice.
