Authority: Dacorum
Appeal type: householder · Householder
Procedure: Written
Development: residential
Postcode: HP3 0HF

Main issues, as the Inspector framed them

Appeal A: whether an application under section 73 may be used to vary a condition where the development implemented on the ground is fundamentally different to that for which the original permission was granted
Appeal B: whether an application under section 73 may be used to vary conditions to permit detached garages that do not have planning permission and were not included in the description of development for the original permission

What decided it

Both appeals were made on an unsound basis because they sought to use section 73 applications to vary conditions in a manner that would require variation of the operative part (description of development) of the original permissions, which is prohibited by established case law.

What the Inspector cited

Development plan policies: Policy CS8 of the Dacorum Borough Core Strategy (2013)
National Planning Policy Framework: Paragraph 111
Judgments: John Leslie Finney v Welsh Ministers & Carmarthenshire County Council; Energiekontor (Uk) Limited and Fiske v Test Valley BC & Woodington Solar Limited
