How does a diffusion differ from a Red Notice, and is it easier to challenge?

A Red Notice is circulated to all INTERPOL member countries, while a diffusion is sent by one country to one or more selected countries. Both must comply with INTERPOL’s Constitution and data-processing rules.

A diffusion is not automatically easier to challenge. The CCF assesses each request individually, including the purpose, accuracy, judicial basis, and compliance of the data.
