Postcode: SE5 8RZ

Main issues, as the Inspector framed them

Whether at the date the enforcement notice was issued, enforcement action could be taken in respect of the alleged breach of planning control (Appeal A, ground (d))
Whether the appellant is entitled to a certificate of lawful use or development for three self-contained flats, having regard to whether deliberate concealment of the unauthorised development occurred (Appeal B)

What decided it

The appellant deliberately concealed the existence of the third flat through false statements and omissions in dealings with multiple Council departments, and as a matter of public policy, this deliberate concealment disentitles him to the immunity from enforcement action that would normally be achieved through the passage of time.
