Does a successful CCF challenge against a Diffusion affect the underlying criminal case in the requesting country?

No. The CCF’s jurisdiction is limited to Interpol’s data systems. A deletion order removes the alert from Interpol’s databases and requires member states to purge it from their national systems, but it has no legal effect on the criminal proceedings in the requesting state. The domestic case continues independently. However, a CCF ruling finding political motivation or human rights concerns can be submitted to courts in third countries as persuasive evidence in extradition proceedings or asylum applications.
