Main issues, as the Inspector framed them
- Whether the enforcement notice is valid and complies with section 173(3) of the Town and Country Planning Act 1990
What decided it
The enforcement notice failed to specify which permitted development regulations the extension should comply with, rendering the notice vague and uncertain and therefore a nullity.
