From Planning Inspectorate decision letters that cite DM27. Dismissed = the council's refusal stood, the policy held; allowed = overturned. The tighter join — this borough's own refusals citing DM27 traced to their specific appeals — is still to come.
Citations, officer spread, ward and application-type counts parsed from published Harrow decision notices (high-confidence parses, approvals and refusals), joined to the canonical application record. One citation = one decision citing the policy. See the policy overview for every policy cited.
