A person surrendered under an extradition treaty arrives in the requesting state expecting to face the charges for which they were handed over. Then a second prosecution begins – for something entirely different. The rule of specialty exists precisely to prevent that outcome.
The rule of specialty is a principle of international extradition law that limits the requesting state to prosecuting or punishing an extradited person only for the offence or offences for which surrender was granted. It is not a creature of INTERPOL's rules, but it interacts directly with Red Notices and diffusions: where a notice supports a request that later expands beyond its stated basis, the rule of specialty becomes the first line of defence.
This page sets out what the rule is, how it operates in practice, and how it connects to the broader picture of challenging a notice before the CCF. As of early 2026, the rule remains one of the most consistently argued protections in extradition proceedings worldwide.
What does the rule of specialty actually prohibit?
The rule prohibits the requesting state from using a surrendered person's physical presence to pursue charges that were not disclosed – and approved – as part of the original extradition request. Once a state obtains surrender on charge A, it cannot simply add charge B once the person is on its territory.
The practical effect is significant. Surrender is granted charge by charge, and each additional charge requires either a fresh extradition request to the requested state, or an express waiver by the person concerned. Without one of those two routes, any prosecution beyond the agreed scope violates the rule.
Where does the obligation sit? Typically in the bilateral or multilateral extradition treaty between the two states, and in the domestic extradition law of the requested state. Different legal systems give the rule different weight. Some permit courts in the requested state to refuse future requests if the original surrender was abused. Others leave enforcement to diplomatic channels. In our practice, the practical weight of the rule varies considerably depending on the treaty in force and the judicial culture of the states involved.
The rule does not apply where the person consents to being tried for additional charges, or where they had a reasonable opportunity to leave the requesting state after release and did not do so. Those are the two classical limitations and they appear, in some form, in most treaty instruments.
How does specialty connect to INTERPOL Red Notices and diffusions?
A Red Notice is a request to locate and provisionally detain a person with a view to extradition. It is not an arrest warrant and not a judicial decision. The notice itself names the offences for which surrender is sought – and that description matters for specialty purposes.
When a Red Notice names one category of offence but the requesting state intends to pursue a broader case, the specialty principle is already in tension before surrender even occurs. In those situations, examining the notice carefully – including the underlying warrant and the stated charge – can reveal a mismatch that affects both the extradition defence and any CCF challenge.
Diffusions present a related problem. A diffusion is an alert circulated directly by a national bureau, outside the formal notice system. It can also be challenged before the CCF. Because diffusions carry less formal specification than a Red Notice, the offence description is sometimes even vaguer – and a vague description is harder to hold a requesting state to on specialty grounds later.
In extradition matters in Western Europe and the Gulf region, we regularly see specialty arguments raised at the provisional-arrest stage, before the full hearing. The argument is most persuasive when it is documented: a clear comparison between the stated offences in the notice or the treaty request and the actual charges pursued. That documentation work begins long before any court date.
Can the rule of specialty support a challenge before the CCF?
The CCF – the Commission for the Control of INTERPOL's Files – reviews the data INTERPOL processes about individuals. Its mandate is grounded in INTERPOL's own Constitution and the Rules on the Processing of Data (the RPD). The CCF does not rule on whether an extradition treaty was violated; that falls to the courts of the requested state.
However, the specialty principle feeds into CCF proceedings indirectly. Where the scope of the charges described in a Red Notice does not match the underlying domestic warrant, that discrepancy raises a data-accuracy concern under the RPD's data-quality requirements. Inaccurate or misleading data is a recognised basis for a deletion request.
Article 2 of INTERPOL's Constitution requires INTERPOL's activities to respect human rights, in the spirit of the Universal Declaration of Human Rights. Where a notice is being used to facilitate a prosecution that goes materially beyond the scope of any lawful extradition request, that is a human-rights argument worth making to the CCF in parallel with any extradition defence.
A deletion request is to be decided within nine months of being found admissible. There is no appeal against a CCF decision; a fresh request requires new elements. That is why the quality of the first file matters so much. A weak first submission based on a poorly documented specialty argument will not be improved by a second attempt unless genuinely new evidence is assembled.
The steps above are the general picture. Your situation depends on the specific charges, the treaty in force and the content of the notice – which is exactly what a confidential assessment looks at.

A common misconception worth correcting
Many people assume that filing a CCF challenge themselves will resolve the problem. In reality, a weak first submission rarely fixes anything – and can actively narrow the options for any subsequent review, because there is no appeal route. The CCF process rewards precision, documented legal argument and correctly sequenced evidence. That is true whether the grounds are specialty, the political-character bar under Article 3 of INTERPOL's Constitution, or a data-accuracy defect under the RPD.
Visas and residence permits are sometimes refused without explanation when a notice or diffusion is active. Applicants do not always connect the two, but in our experience the data INTERPOL holds is often the root cause. A data check – filing an access request to learn what INTERPOL actually holds – is frequently the right first step, before any challenge is filed.

Frequently asked questions
What is the short answer?
The rule of specialty requires a state that receives an extradited person to prosecute them only for the offences for which surrender was granted. Any charge beyond that scope either requires a fresh extradition request to the original requested state or the person's own consent. The rule sits in the extradition treaty between the two states and in the domestic extradition law of the state that surrendered the person.
Does this create any obligation to arrest me?
No. A Red Notice does not oblige any country to arrest you; each state decides under its own law. The rule of specialty is a separate concept that operates after surrender – it limits what the requesting state may do with you once you have been handed over. A Red Notice is not an arrest warrant and not a judicial decision. The specialty rule becomes relevant once extradition proceedings are underway or have concluded.
Where does this sit in the CCF process?
The CCF reviews INTERPOL data for compliance with the RPD's data-accuracy and data-quality requirements and with INTERPOL's Constitution. A specialty-related discrepancy between the charges named in a notice and the actual domestic warrant can amount to a data-accuracy defect – a recognised basis for a deletion request. A deletion request is decided within nine months of admissibility. There is no appeal; a review requires new elements.
