A blocked INTERPOL notice is not the same as a deleted notice. This distinction is frequently misunderstood and, in high-stakes cases, the consequences of that misunderstanding can be severe.

In exceptional situations, the INTERPOL General Secretariat (“IPSG”) may intervene to temporarily block a Red Notice or diffusion while the Commission for the Control of INTERPOL’s Files (“CCF”) examines the case. This intervention is known as a provisional measure.

This intervention does not determine the legality of the notice. Instead, it suspends its operational effect while a substantive review is carried out.

What are the practical effects of a “Blocked” Red Notice?

When a notice is blocked, access to the data is frozen across INTERPOL’s systems. Member states are no longer able to act on that data, meaning that arrests, detentions, or extradition proceedings that rely exclusively on INTERPOL channels are effectively neutralised. Although the data remains on file, it becomes unusable until the CCF reaches a final decision. In practical terms, the individual is protected from INTERPOL-based enforcement actions and may usually travel freely, subject always to domestic law and any parallel national measures.

The legal basis for provisional measures is found in Article 37 of the Statute of the CCF, which allows the Requests Chamber to impose such measures at any point during the proceedings. The wording of the provision is deliberately broad, giving the Commission flexibility to act swiftly where necessary. 

When does INTERPOL block a Red Notice?

Practically, blocking tends to be imposed in situations of acute urgency, particularly where extradition is imminent, where detention depends solely on INTERPOL data, or where the individual has been granted protective status, such as refugee protection. These are scenarios where delay would risk irreversible harm before the legality of the data could be properly assessed.

Despite the importance of these decisions, the process suffers from a significant lack of transparency. When the IPSG applies provisional measures, it does not provide the affected individual with a detailed explanation or legal reasoning. Applicants are informed that the data has been blocked, but they are not told why, nor are they given any indication of how the CCF is likely to rule on the merits of the case. The underlying rationale is only partially reflected in INTERPOL’s internal processing instructions, which are not publicly accessible. As a result, individuals facing potentially life-altering consequences are often left in a state of uncertainty during a critical phase of the proceedings.

The significance of provisional measures becomes particularly clear in cases involving serious human rights risks. In one such case, the applicant was already in detention and facing extradition to a country with a well-documented record of human rights abuses. The individual had been convicted in absentia, raising substantial concerns about violations of fair trial rights, and there was a credible risk of torture or even death if extradition were carried out. Recognising the urgency, the IPSG, in consultation with the CCF, swiftly blocked access to the data. This action prevented the use of INTERPOL channels that could have facilitated extradition and created the necessary space for a thorough review of the data’s compliance with INTERPOL’s rules. Without this intervention, the harm would have been irreversible.

Blocking is NOT Deletion

It is important to stress that blocking does not automatically lead to deletion. While experience shows that many cases in which data is blocked ultimately result in removal, this outcome is never guaranteed. The CCF consistently emphasises that provisional measures do not prejudge the final decision, and applicants are expressly informed that the data may ultimately be either deleted or retained. Blocking is therefore best understood as a temporary safeguard rather than a substantive determination.

This is borne out by the CCF’s official 2021 statistics, which show that out of 478 deletion requests examined that year, provisional blocking measures were imposed in 311 cases, representing approximately 65 percent of the total. This high proportion suggests that in a majority of cases, serious concerns about compliance with INTERPOL’s data processing rules are identified at an early stage, well before the Commission reaches its final verdict.

Nevertheless, provisional measures have clear limits. They provide time, not certainty. Although blocking can immediately prevent arrest or extradition based on INTERPOL data, the CCF may ultimately decide that the notice complies with INTERPOL’s rules and should be retained. For this reason, the period during which data is blocked is often the most critical phase of the case, requiring careful legal strategy and thorough substantiation of all relevant human rights, procedural, and jurisdictional arguments.

A blocked INTERPOL notice can, therefore, be a powerful form of temporary protection, but it should never be mistaken for a final “victory”. 

Blocking is a shield, not a verdict. The final outcome depends entirely on the CCF’s assessment of the data’s compliance with INTERPOL’s legal framework.
