Article 19

Extradition

1. The offences set forth in Articles 5 to 7 and 9 of this Convention shall be deemed to be included as extraditable offences in any extradition treaty existing between any of the Parties before the entry into force of this Convention. Parties undertake to include such offences as extraditable offences in every extradition treaty to be subsequently concluded between them.

2. When a Party which makes extradition conditional on the existence of a treaty receives a request for extradition from another Party with which it has no extradition treaty, the requested Party may, if it so decides, consider this Convention as a legal basis for extradition in respect of the offences set forth in Articles 5 to 7 and 9 of this Convention. Extradition shall be subject to the other conditions provided by the law of the requested Party.

3. Parties which do not make extradition conditional on the existence of a treaty shall recognise the offences set forth in Articles 5 to 7 and 9 of this Convention as extraditable offences between themselves, subject to the conditions provided by the law of the requested Party.

4. Where necessary, the offences set forth in Articles 5 to 7 and 9 of this Convention shall be treated, for the purposes of extradition between Parties, as if they had been committed not only in the place in which they occurred but also in the territory of the Parties that have established jurisdiction in accordance with Article 14.

5. The provisions of all extradition treaties and agreements concluded between Parties in respect of offences set forth in Articles 5 to 7 and 9 of this Convention shall be deemed to be modified as between Parties to the extent that they are incompatible with this Convention.

Article 20

Exclusion of the political exception clause

1. None of the offences referred to in Articles 5 to 7 and 9 of this Convention, shall be regarded, for the purposes of extradition or mutual legal assistance, as a political offence, an offence connected with a political offence, or as an offence inspired by political motives. Accordingly, a request for extradition or for mutual legal assistance based on such an offence may not be refused on the sole ground that it concerns a political offence or an offence connected with a political offence or an offence inspired by political motives.

2. Without prejudice to the application of Articles 19 to 23 of the Vienna Convention on the Law of Treaties of 23 May 1969 to the other Articles of this Convention, any State or the European Community may, at the time of signature or when depositing its instrument of ratification, acceptance, approval or accession of the Convention, declare that it reserves the right to not apply paragraph 1 of this Article as far as extradition in respect of an offence set forth in this Convention is concerned. The Party undertakes to apply this reservation on a case-by-case basis, through a duly reasoned decision.

3. Any Party may wholly or partly withdraw a reservation it has made in accordance with paragraph 2 by means of a declaration addressed to the Secretary-General of the Council of Europe which shall become effective as from the date of its receipt.

4. A Party which has made a reservation in accordance with paragraph 2 of this Article may not claim the application of paragraph 1 of this Article by any other Party; it may, however, if its reservation is partial or conditional, claim the application of this article in so far as it has itself accepted it.

5. The reservation shall be valid for a period of three years from the day of the entry into force of this Convention in respect of the Party concerned. However, such reservation may be renewed for periods of the same duration.

6. 12 months before the date of expiry of the reservation, the Secretary-General of the Council of Europe shall give notice of that expiry to the Party concerned. No later than three months before expiry, the Party shall notify the Secretary-General of the Council of Europe that it is upholding, amending or withdrawing its reservation. Where a Party notifies the Secretary-General of the Council of Europe that it is upholding its reservation, it shall provide an explanation of the grounds justifying its continuance. In the absence of notification by the Party concerned, the Secretary-General of the Council of Europe shall inform that Party that its reservation is considered to have been extended automatically for a period of six months. Failure by the Party concerned to notify its intention to uphold or modify its reservation before the expiry of that period shall cause the reservation to lapse.

7. Where a Party does not extradite a person in application of this reservation, after receiving an extradition request from another Party, it shall submit the case, without exception whatsoever and without undue delay, to its competent authorities for the purpose of prosecution, unless the requesting Party and the requested Party agree otherwise. The competent authorities, for the purpose of prosecution in the requested Party, shall take their decision in the same manner as in the case of any offence of a grave nature under the law of that Party. The requested Party shall communicate, without undue delay, the final outcome of the proceedings to the requesting Party and to the Secretary-General of the Council of Europe, who shall forward it to the Consultation of the Parties provided for in Article 30.

8. The decision to refuse the extradition request on the basis of this reservation shall be forwarded promptly to the requesting Party. If within a reasonable time no judicial decision on the merits has been taken in the requested Party according to paragraph 7, the requesting Party may communicate this fact to the Secretary-General of the Council of Europe, who shall submit the matter to the Consultation of the Parties provided for in Article 30. This Consultation shall consider the matter and issue an opinion on the conformity of the refusal with the Convention and shall submit it to the Committee of Ministers for the purpose of issuing a declaration thereon. When performing its functions under this paragraph, the Committee of Ministers shall meet in its composition restricted to the States Parties.

Article 21

Discrimination clause

1. Nothing in this Convention shall be interpreted as imposing an obligation to extradite or to afford mutual legal assistance, if the requested Party has substantial grounds for believing that the request for extradition for offences set forth in Articles 5 to 7 and 9 or for mutual legal assistance with respect to such offences has been made for the purpose of prosecuting or punishing a person on account of that person's race, religion, nationality, ethnic origin or political opinion or that compliance with the request would cause prejudice to that person's position for any of these reasons.

2. Nothing in this Convention shall be interpreted as imposing an obligation to extradite if the person who is the subject of the extradition request risks being exposed to torture or to inhuman or degrading treatment or punishment.

3. Nothing in this Convention shall be interpreted either as imposing an obligation to extradite if the person who is the subject of the extradition request risks being exposed to the death penalty or, where the law of the requested Party does not allow for life imprisonment, to life imprisonment without the possibility of parole, unless under applicable extradition treaties the requested Party is under the obligation to extradite if the requesting Party gives such assurance as the requested Party considers sufficient that the death penalty will not be imposed or, where imposed, will not be carried out, or that the person concerned will not be subject to life imprisonment without the possibility of parole.

Article 22

Spontaneous information

1. Without prejudice to their own investigations or proceedings, the competent authorities of a Party may, without prior request, forward to the competent authorities of another Party information obtained within the framework of their own investigations, when they consider that the disclosure of such information might assist the Party receiving the information in initiating or carrying out investigations or proceedings, or might lead to a request by that Party under this Convention.

2. The Party providing the information may, pursuant to its national law, impose conditions on the use of such information by the Party receiving the information.

3. The Party receiving the information shall be bound by those conditions.

4. However, any Party may, at any time, by means of a declaration addressed to the Secretary-General of the Council of Europe, declare that it reserves the right not to be bound by the conditions imposed by the Party providing the information under paragraph 2 above, unless it receives prior notice of the nature of the information to be provided and agrees to its transmission.
