   Added to PlanIndex

The applicant withdrew this application before the council decided it, so it carries no planning weight and no fee refund is automatic. Withdrawal often follows officer feedback that a refusal was likely.

The applicant is free to submit a revised application at any time, and many withdrawn schemes return in amended form, so the site is worth watching if the proposal affected you.

A lawful development certificate is a legal determination, not a planning judgement. It asks the council to confirm either that existing use or works are lawful, often through the passage of time, or that a proposal would not need planning permission at all. The applicant must prove the facts; the merits of the scheme are not considered.
