Outcomes
Claim dismissed.
The Inspector's approach to water neutrality was lawful and consistent with Natural England's guidance. The request to hold the appeal in abeyance was insufficiently articulated, and there was no obligation to make a split decision in the absence of a clear request.
Ground 1 (Water Neutrality) rejected.
The Inspector reasonably interpreted Natural England's guidance, considering the Claimants' prior occupation but requiring water neutrality demonstration. His approach was within the range of reasonable options open to him.
Ground 2 (Abeyance) rejected.
The request to hold the appeal in abeyance lacked clarity and practicality. It was not a principal important issue requiring explicit addressing.
Ground 3 (Split Decision) rejected.
No clear request for a split decision was made. The Inspector's handling of the stable block issue did not render his decision unlawful.
