Judgment
Lord Justice Sullivan:
Introduction
On the 9 th October 2014 we allowed this appeal, set aside the Judge’s Order quashing the Inspector’s decision, and dismissed the Respondent’s application under section 288 of the Town and Country Planning Act 1990 (“the Act”). We said that we would give our reasons in due course. These are my reasons for allowing the appeal.

The Aerodrome, which straddles the boundary between the two local planning authorities, is located in the Metropolitan Green Belt.
There is no challenge to the Inspector’s conclusion that the proposal was inappropriate development in the Green Belt. In paragraph 19 of her decision the Inspector said:
“Submissions were made as to whether the Green Belt balancing exercise should follow the approach set out in the River Club judgment. Even though the judgment was made on the policy set out in Planning Policy Guidance 2, the wording in the Framework is very similar and I intend to fo
