The Rule of Speciality in Extradition
Which offences, measures and onward transfers remain permissible after extradition – and where the protection ends.
By Dr Julius Hagen, Attorney at Law
What the rule of speciality protects
The rule of speciality limits the authority that a requesting state receives through extradition. As a general rule, the person may be punished, deprived of liberty or subjected to specified prosecution measures only for the offence covered by the surrender decision. The German statutory framework is set out in section 11 IRG.
The protection attaches to the concrete offence, not merely its legal label. The time, place, factual conduct and alleged participation must be described precisely enough in the request and surrender decision to distinguish later allegations. A different legal characterisation of the same factual event is not automatically a breach; a separate new allegation may be impermissible.
Which measures are covered
Speciality does not prevent every investigation. The other offence may, for example, be used as evidence relating to the surrendered offence, but it may not itself form the basis of a conviction or an aggravating qualification. The rule also covers significant restrictions of liberty and certain measures that could not be taken in the person’s absence.
Where surrender was granted for enforcement of a sentence, enforcement may extend only to the offences covered by the surrender decision. Whether a specific measure crosses the speciality line depends on the law and actual practice of the requesting state.
Onward surrender and the possibility of leaving
Under section 11(1) no. 2 IRG the person generally may not be surrendered, transferred or deported to a third state without Germany’s consent where that would circumvent the original protection. Once the relevant proceedings have ended, there must also be a legal and practical possibility to leave the requesting state (section 11(1) no. 3 IRG ).
The possibility of leaving must be real, not merely theoretical. Necessary travel documents must be available and state measures must not prevent departure. For statutory time limits, it may also matter when proceedings have finally ended or a conditional release is treated as equivalent to completion.
When speciality comes to an end
The protection may be lifted by Germany’s subsequent consent to further proceedings, including under sections 35 and 36 IRG. Section 11(2) IRG also addresses expiry of the one-month period after completion, return to the requesting state or re-surrender. The person must have had a real opportunity to leave; a merely abstract legal possibility is insufficient.
Consent to simplified surrender may also affect speciality. The exact declaration, the applicable treaty or EU framework and the proceedings actually intended in the requesting state must be assessed from the documents in the individual case.
Specific features of a European Arrest Warrant
For an EAW, speciality derives from Article 27 of the Framework Decision on the European Arrest Warrant. Section 82 IRG excludes section 11 IRG from the German admissibility analysis; compliance is governed through the EU rules and the judicial authorities involved.
The EAW protection generally concerns other offences committed before surrender. It does not cover later conduct and contains exceptions, including certain proceedings without a restriction of liberty, remaining voluntarily for more than 45 days after final discharge or later consent to an extension.
How speciality is enforced
The IRG does not prescribe a single monitoring procedure for compliance abroad. Binding assurances, notice of the final decision and scrutiny of the actual indictment, detention measure or enforcement step may be important.
If a breach is suspected, the German surrender decision, the original request and the measures taken abroad must be compared. Enforcement will usually require counsel in the requesting state, who can assess whether consent to an extension was required and which remedies are available.
