Artikel 26

1. The Parties shall co-operate with each other, in accordance with the provisions of this Convention and in accordance with the relevant applicable international and regional instruments and arrangements agreed on the basis of uniform or reciprocal legislation and with their domestic law, to the widest extent possible for the purposes of investigations, prosecutions and judicial proceedings concerning the offences referred to in Articles 15 to 17 of this Convention, including seizure and confiscation.
2. The Parties shall co-operate to the widest extent possible, in accordance with the relevant applicable international, regional and bilateral treaties on extradition and mutual assistance in criminal matters and in accordance with their domestic law, concerning the offences referred to in Articles 15 to 17 of this Convention.
3. In matters of international co-operation, whenever dual criminality is considered to be a requirement, it shall be deemed to have been fulfilled, irrespective of whether the laws of the requested State place the offence within the same category of offence or use the same term to denominate the offence as the requesting State, if the conduct underlying the offence in respect of which legal mutual assistance or extradition is requested is a criminal offence under the laws of both Parties.
4. If a Party that makes extradition or mutual legal assistance in criminal matters conditional on the existence of a treaty receives a request for extradition or legal assistance in criminal matters from a Party with which it has no such treaty, it may, acting in full compliance with its obligations under international law and subject to the conditions provided for by its own domestic law, consider this Convention to be the legal basis for extradition or mutual legal assistance in criminal matters in respect of the offences referred to in Articles 15 to 17 of this Convention.
