The applicable treaty, the connection between the offence and Austria, and the precise basis for an exception matter to the person sought. Austrian criminal jurisdiction can prevent extradition to a third country. Where § 16 ARHG applies, paragraph 1 prohibits extradition for offences within that jurisdiction, yet paragraph 2 permits exceptions. Pending proceedings in Austria alone do not settle the extradition question.

01 Question 1

What is unresolved in the third-country proceedings?

All paths at a glance

Overview of all answers.

01

Clarify the applicable law and places of commission

Provide the request and evidence of the places of conduct and result. The treaty and Austrian jurisdiction must be assessed first.

02

Examine the precise exception relied on

Establish whether jurisdiction solely on another state’s behalf under Z 1 or special circumstances under Z 2 are invoked. Paragraph 3 still requires examination.

03

Check the same acts, grounds and finality

Provide the complete Austrian decision. Termination on the grounds in § 9 Abs. 3 ARHG must be distinguished from other terminations of prosecution.

04

Assess overall consequences and detention separately

The additional disadvantage bar concerns § 16 Abs. 2 Z 2 ARHG. If detention continues or transfer has been announced, please also call.

Establish which treaty applies first

Under § 1 ARHG, statutory provisions yield to any contrary international agreement. Defence counsel must therefore identify the requesting state, the applicable extradition treaty, and any effective supplementary provisions or reservations. The assessment below under § 16 ARHG assumes that no overriding treaty rule departs from it. Merely describing a state as a third country does not establish a particular bar to extradition.

The European Convention on Extradition demonstrates the importance of this sequence. Art. 7 addresses the place of commission, Art. 8 covers pending proceedings for the same acts, and Art. 9 concerns a final judgment. The first two provisions permit refusal if their requirements are met; Art. 9, however, distinguishes a final judgment from a decision not to institute proceedings or to terminate them. One must separately assess which rule applies in relations with the particular state. A European Arrest Warrant falls under the separate procedure of the EU-JZG.

Assess Austrian jurisdiction over the specific offence

§ 16 Abs. 1 ARHG addresses the criminal act. Austrian criminal law governs offences committed in Austria pursuant to § 62 StGB. Under § 67 Abs. 2 StGB, the place of commission depends, among other things, on where the person acted and where a result forming part of the offence occurred wholly or partly, or should have occurred according to the perpetrator’s conception. Consequently, several locations may matter in a cross-border case.

Defence counsel must link the act described in the request to these jurisdictional grounds. An Austrian residential address does not by itself prove that an offence occurred in Austria. Filing a criminal complaint in Austria also does not substitute for the jurisdictional assessment. Other statutory grounds may apply to offences committed abroad and demand their own evaluation. The protection of Austrian citizens under § 12 ARHG concerns nationality and must remain distinct from this offence-based bar.

Two exceptions allow extradition to be considered further

If Austria exercises jurisdiction solely on behalf of another state, § 16 Abs. 2 Z 1 ARHG provides that the basic prohibition does not preclude extradition. The legal basis of that jurisdiction is decisive. Parallel investigation by another state or the fact that another state assigned a case number first does not establish this exception.

§ 16 Abs. 2 Z 2 ARHG governs a distinct scenario where special circumstances must favour holding the criminal proceedings in the requesting state, in particular regarding the establishment of truth, sentencing, and enforcement. Defence counsel should therefore identify which evidence, related allegations, or enforcement conditions substantiate this claimed preference. A general claim that proceedings would be easier abroad cannot substitute for a justification specific to the case, and both exceptions remain subject to paragraph 3.

Austrian case outcomes can bar both exceptions

The first sentence of § 16 Abs. 3 ARHG prohibits extradition if the person has already been finally convicted or finally acquitted in Austria for the relevant offence, even where either exception applies. This provision also covers the termination of prosecution on grounds other than those listed in § 9 Abs. 3 ARHG. This assessment requires the complete decision and a clear connection to the act covered by the extradition request.

Termination of proceedings must therefore not be treated as equivalent to a final acquittal in every case. Where Austrian criminal jurisdiction rests solely on § 65 Abs. 1 Z 2 StGB, § 9 Abs. 3 ARHG permits prosecution to be discontinued, subject to its requirements. § 16 Abs. 3 specifically excludes that ground from the bar described above. The precise ground, the facts covered, and, for a judgment, its finality matter more than a general statement that the case has been closed in Austria.

Substantial disadvantage is an additional, limited bar

Paragraph 3 grants further protection specifically for the situation under § 16 Abs. 2 Z 2 ARHG. The law also prohibits extradition where there is reason to fear that a conviction in the other state would place the person at a substantially greater disadvantage in its overall effect than under Austrian law. This additional assessment concerns the claimed preference for foreign proceedings. Its wording does not extend this protection to every extradition, nor does it apply automatically to jurisdiction exercised on another state’s behalf under Z 1.

The comparison demands a reasoned assessment of the specific legal consequences to be expected. A higher foreign maximum sentence alone fails to settle the statutory overall assessment. Defence counsel must establish the relevant foreign rules and their application to the allegation, then compare the resulting consequences with those under Austrian law. Any additional disadvantages relied on require a reliable legal basis. Therefore, a more severe foreign sanction does not automatically prevent extradition; the decisive question remains whether a substantial disadvantage exists in the overall effect.

Documents needed to support the objection

The complete extradition request, comprising the description of the acts, the arrest warrant or judgment, and the necessary translations, serves as the starting point. The file must also contain evidence regarding the places of conduct and result, Austrian case numbers, and Austrian decisions. Documentation should cover the precise grounds, scope, and, where applicable, finality of any earlier case outcome. Relatives can collect existing records, but any personal statement on the allegations should first be discussed with defence counsel.

When an exception under Z 2 is invoked, counsel must also consider the claimed special circumstances and any possible disadvantage from a foreign conviction. Counsel’s submissions should show separately for each offence which Austrian jurisdictional ground applies and which exception is invoked. They should also indicate which objection counters that exception. Missing foreign provisions or unclear grounds for terminating proceedings must remain identifiable as unresolved issues. A mere reference to Austrian proceedings does not dispense with this assessment.

Raise the extradition bar in the detention proceedings too

Extradition detention under § 29 Abs. 1 ARHG requires sufficient grounds to assume an offence subject to extradition. If a bar to extradition is established, defence counsel must raise its implications for continued extradition detention and assess an application for release. Merely raising an objection does not produce automatic release. Defence counsel must also assess the other requirements for detention and possible less restrictive measures.

Any additional Austrian pre-trial detention or imprisonment demands its own legal assessment. Successfully resisting extradition does not automatically eliminate another legal basis for detention. Where detention continues or a transfer has been announced, counsel should receive current court orders, proof of service, and scheduled dates immediately. The assessment under § 16 ARHG must be linked to the applications and appeals required in the actual case, as an informal enquiry cannot replace a procedural step.

FAQ

Questions about jurisdiction and extradition

Do Austrian criminal proceedings prevent every extradition? +

Pending proceedings alone fail to provide that assurance. One must first assess the applicable treaty rules and Austrian jurisdiction over the specific act. Where § 16 ARHG applies, one must also examine the exceptions in paragraph 2 and the additional bars in paragraph 3.

Does every termination of proceedings in Austria have the same effect? +

§ 16 Abs. 3 ARHG distinguishes between a final conviction, a final acquittal, and a termination of prosecution, making the grounds and the facts covered decisive. A termination based on the grounds listed in § 9 Abs. 3 ARHG specifically falls outside the bar that provision establishes for other terminations of prosecution.

Does protection against disadvantage apply to both exceptions? +

The additional bar, which expressly refers to § 16 Abs. 2 Z 2 ARHG, rests on substantial disadvantage in the overall effect. That sentence does not prescribe the same assessment for jurisdiction exercised on another state’s behalf under Z 1. Separate examination remains necessary for other applicable bars to extradition.
