Main issues, as the Inspector framed them
- Whether the condition's reference to Class E is necessary and reasonable having regard to the Green Belt and its openness
What decided it
The existence of a fallback position through granted certificates of lawfulness meant the risk to Green Belt openness already existed, making the removal of Class E permitted development rights unnecessary.
