Main issues, as the Inspector framed them
- Whether the siting of a mobile home for residential use as a separate dwellinghouse is immune from enforcement action and is thus a lawful use
What decided it
The absence of sufficiently precise and unambiguous evidence to demonstrate that residential occupation of the mobile home had been continuous for any ten-year period meant the use could not be established as immune from enforcement action.
