Can a Red Notice be issued while criminal proceedings in the requesting country are still ongoing?

Yes. A Red Notice does not require a final conviction — it can be issued at any stage after formal charges, including during pre-trial investigation. The requesting country must demonstrate that an arrest warrant exists domestically and that the alleged offence meets Interpol’s minimum gravity threshold. However, notices issued during early investigative stages are more vulnerable to challenge on proportionality and due process grounds, particularly if the subject has not been formally notified of charges or given an opportunity to respond in the originating jurisdiction.
