The member States of the Council of Europe, signatory to this Protocol,
Desirous of facilitating the application of the European Convention on Mutual Assistance in Criminal Matters opened for signature in Strasbourg on 20th April 1959 (hereinafter referred to as "the Convention") in the field of fiscal offences;
Considering it also desirable to supplement the Convention in certain other respects,
Have agreed as follows:

Chapter I

Article 1

The Contracting Parties shall not exercise the right provided for in Article 2.a of the Convention to refuse assistance solely on the ground that the request concerns an offence which the requested Party considers a fiscal offence.

Article 2

1. In the case where a Contracting Party has made the execution of letters rogatory for search or seizure of property dependent on the condition that the offence motivating the letters rogatory is punishable under both the law of the requesting Party and the law of the requested Party, this condition shall be fulfilled, as regards fiscal offences, if the offence is punishable under the law of the requesting Party and corresponds to an offence of the same nature under the law of the requested Party.
2. The request may not be refused on the ground that the law of the requested Party does not impose the same kind of tax or duty or does not contain a tax, duty, customs and exchange regulation of the same kind as the law of the requesting Party.

Chapter II

Article 3

The Convention shall also apply to:

1. the service of documents concerning the enforcement of a sentence, the recovery of a fine or the payment of costs of proceedings;
2. measures relating to the suspension of pronouncement of a sentence or of its enforcement, to conditional release, to deferment of the commencement of the enforcement of a sentence or to the interruption of such enforcement.

Chapter III

Article 4

Article 22 of the Convention shall be supplemented by the following text, the original Article 22 of the Convention becoming paragraph 1 and the below-mentioned provisions becoming paragraph 2:
"2 Furthermore, any Contracting Party which has supplied the above-mentioned information shall communicate to the Party concerned, on the latter's request in individual cases, a copy of the convictions and measures in question as well as any other information relevant thereto in order to enable it to consider whether they necessitate any measures at national level. This communication shall take place between the Ministries of Justice concerned."

2. Any State may, at the time of signature or when depositing its instrument of ratification, acceptance, approval or accession, declare that it reserves the right:
