Article 8 [Wederzijdse rechtshulp]

Contracting States shall afford one another the widest measure of mutual assistance in criminal matters in connection with proceedings brought in respect of the offences mentioned in Article 1 or 2. The law of the requested State concerning mutual assistance in criminal matters shall apply in all cases. Nevertheless this assistance 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.

Nothing in this Convention shall be interpreted as imposing an obligation to afford mutual assistance if the requested State has substantial grounds for believing that the request for mutual assistance in respect of an offence mentioned in Article 1 or 2 has been made for the purpose of prosecuting or punishing a person on account of his race, religion, nationality or political opinion or that that person's position may be prejudiced for any of these reasons.

The provisions of all treaties and arrangements concerning mutual assistance in criminal matters applicable between Contracting States, including the European Convention on Mutual Assistance in Criminal Matters, are modified as between Contracting States to the extent that they are incompatible with this Convention.
