Planning analysis: In Perrin v North Devon DC, the High Court quashed the grant of planning permission by North Devon DC for an open market dwelling in a small settlement. It held that the planning committee's reasons for departing from officers' repeated recommendation of refusal were inadequate and irrational, because they failed to explain why an open market dwelling should be preferred over the retention of the site for affordable housing-led development under the local plan. The court also held that the decision was tainted by apparent bias arising principally from a senior councillor's participation, viewed against his relationship with the applicants, his involvement in calling in the application, and his role in the committee's consideration.
