INTERNATIONAL CO-OPERATION

Article 25

General principles and measures for international co-operation

1. The Parties shall co-operate with each other, in accordance with the provisions of relevant international instruments on international co-operation in criminal matters, or arrangements agreed on the basis of uniform or reciprocal legislation, and in accordance with their national law, to the widest extent possible for the purposes of investigations and proceedings concerning criminal offences established in accordance with this Convention.

2. Where no international instrument or arrangement referred to in paragraph 1 is in force between Parties, Articles 26 to 31 of this chapter shall apply.

2. Mutual legal assistance under paragraph 1 of this article may be refused if the requested Party believes that compliance with the request would undermine its fundamental interests, national sovereignty, national security or ordre public.

3. Parties shall not invoke bank secrecy as a ground to refuse any co-operation under this chapter.

Article 27

Extradition

1. The criminal offences established in accordance with this Convention shall be deemed to be included as extraditable offences in any extradition treaty existing between or among the Parties. The Parties undertake to include such offences as extraditable offences in any extradition treaty to be concluded between or among them.

2. If a Party that makes extradition conditional on the existence of a treaty receives a request for extradition from another Party with which it does not have an extradition treaty, it may consider this Convention as the legal basis for extradition with respect to any criminal offence established in accordance with this Convention.

3. Parties that do not make extradition conditional on the existence of a treaty shall recognise criminal offences established in accordance with this Convention as extraditable offences between themselves.

4. Extradition shall be subject to the conditions provided for by the law of the requested Party or by applicable extradition treaties, including the grounds on which the requested Party may refuse extradition.

5. If extradition for a criminal offence established in accordance with this Convention is refused solely on the basis of the nationality of the person sought, or because the requested Party deems that it has jurisdiction over the offence, the requested Party shall submit the case to its competent authorities for the purpose of prosecution unless otherwise agreed with the requesting Party, and shall report the final outcome to the requesting Party in due course.

Article 28

Spontaneous information

Without prejudice to its own investigations or proceedings, a Party may without prior request forward to another Party information on facts when it considers that the disclosure of such information might assist the receiving Party in initiating or carrying out investigations or proceedings concerning criminal offences established in accordance with this Convention or might lead to a request by that Party under this chapter.

Article 29

Central authority

3. Any request or communication under paragraphs 1 and 2 of this article may be made through the International Criminal Police Organisation (Interpol).
