The Department monitors the professional quality standards of the Planning Inspectorate through the Advisory Panel on Standards. The Panel prepares an annual report for the Secretary of State on matters affecting the maintenance of quality within the Inspectorate. In doing so panel members have access to inspectors' reports and decisions and to other relevant material associated with resolved complaints, High Court challenges or Parliamentary and Health Service Ombudsman cases.
The target is that 99 per cent. of the Inspectorate's casework should be free from justified complaint.
