The grant of a temporary planning permission did not operate to cancel an existing established use. A planning condition requiring removal of hangars was invalid because it did not fairly or reasonably relate to the permitted development. The grant of an unnecessary planning permission does not exclude a landowner from relying on an existing use right. Where an impossible condition is attached the permission might be read without it.
Viscount Dilhorne said: ‘If, however, the grant of planning permission, whether it be permission to build or for a change of use, is of such a character that the implementation of the permission leads to the creation of a new planning unit, then I think that it is right to say that existing use rights attaching to the former planning unit are extinguished.’ and
‘It follows that the conditions imposed must be for a planning purpose and not for any ulterior one, and that they must fairly and reasonably relate to the development permitted. Also they must not be so unreasonable that no reasonable planning authority could have imposed them . .’
