Can I challenge a diffusion through the CCF, or does the process only apply to Red Notices?

Diffusions are fully subject to CCF review. Although diffusions are less formal than Red Notices — circulated directly between member countries rather than through the General Secretariat — Interpol’s Rules on the Processing of Data apply equally. Many diffusions fail to meet even basic data quality standards because they bypass central vetting. CCF challenges against diffusions often succeed on procedural grounds: missing mandatory fields, insufficient offence descriptions, or failure to specify the legal basis for the request. The deletion process mirrors that for Red Notices, including access to both chambers.
