[Strasbourg, 8.XI.2001]

The member States of the Council of Europe, signatory to this Protocol,
Having regard to their undertakings under the Statute of the Council of Europe;
Desirous of further contributing to safeguard human rights, uphold the rule of law and support the democratic fabric of society;
Considering it desirable to that effect to strengthen their individual and collective ability to respond to crime;
Decided to improve on and supplement in certain aspects the European Convention on Mutual Assistance in Criminal Matters done at Strasbourg on 20 April 1959 (hereinafter referred to as "the Convention"), as well as the Additional Protocol thereto, done at Strasbourg on 17 March 1978;
Taking into consideration the Convention for the Protection of Human Rights and Fundamental Freedoms, done at Rome on 4 November 1950, as well as the Convention for the Protection of Individuals with regard to Automatic Processing of Personal Data, done at Strasbourg on 28 January 1981,
Have agreed as follows: 

Chapter I 

Article 1 – Scope
Article 1 of the Convention shall be replaced by the following provisions:
"1 The Parties undertake promptly to afford each other, in accordance with the provisions of this Convention, the widest measure of mutual assistance in proceedings in respect of offences the punishment of which, at the time of the request for assistance, falls within the jurisdiction of the judicial authorities of the requesting Party.
2 This Convention does not apply to arrests, the enforcement of verdicts or offences under military law which are not offences under ordinary criminal law.
3 Mutual assistance may also be afforded in proceedings brought by the administrative authorities in respect of acts which are punishable under the national law of the requesting or the requested Party by virtue of being infringements of the rules of law, where the decision may give rise to proceedings before a court having jurisdiction in particular in criminal matters. 
4 Mutual assistance shall not be refused solely on the grounds that it relates to acts for which a legal person may be held liable in the requesting Party."

Article 2 – Presence of officials of the requesting Party
Article 4 of the Convention shall be supplemented by the following text, the original Article 4 of the Convention becoming paragraph 1 and the provisions below becoming paragraph 2:
"2 Requests for the presence of such officials or interested persons should not be refused where that presence is likely to render the execution of the request for assistance more responsive to the needs of the requesting Party and, therefore, likely to avoid the need for supplementary requests for assistance." 

Article 3 – Temporary transfer of detained persons to the territory of the requesting Party
Article 11 of the Convention shall be replaced by the following provisions:
"1 A person in custody whose personal appearance for evidentiary purposes other than for standing trial is applied for by the requesting Party shall be temporarily transferred to its territory, provided that he or she shall be sent back within the period stipulated by the requested Party and subject to the provisions of Article 12 of this Convention, in so far as these are applicable.
Transfer may be refused if:
a the person in custody does not consent;
b his or her presence is necessary at criminal proceedings pending in the territory of the requested Party;
c transfer is liable to prolong his or her detention, or
d there are other overriding grounds for not transferring him or her to the territory of the requesting Party. 
2 Subject to the provisions of Article 2 of this Convention, in a case coming within paragraph 1, transit of the person in custody through the territory of a third Party, shall be granted on application, accompanied by all necessary documents, addressed by the Ministry of Justice of the requesting Party to the Ministry of Justice of the Party through whose territory transit is requested. A Party may refuse to grant transit to its own nationals. 
3 The transferred person shall remain in custody in the territory of the requesting Party and, where applicable, in the territory of the Party through which transit is requested, unless the Party from whom transfer is requested applies for his or her release." 

Article 4 – Channels of communication
Article 15 of the Convention shall be replaced by the following provisions: 
"1 Requests for mutual assistance, as well as spontaneous information, shall be addressed in writing by the Ministry of Justice of the requesting Party to the ministry of justice of the requested Party and shall be returned through the same channels.

6 Requests for copies of convictions and measures as referred to in Article 4 of the Additional Protocol to the Convention may be made directly to the competent authorities. Any Contracting State may, at any time, by a declaration addressed to the Secretary General of the Council of Europe, define what authorities it will, for the purpose of this paragraph, deem competent authorities.
7 In urgent cases, where direct transmission is permitted under this Convention, it may take place through the International Criminal Police Organisation (Interpol).
8 Any Party may, at any time, by a declaration addressed to the Secretary General of the Council of Europe, reserve the right to make the execution of requests, or specified requests, for mutual assistance dependent on one or more of the following conditions:

b that requests, except urgent requests, be forwarded to the central authority designated in that declaration; 
c that, in case of direct transmission for reasons of urgency, a copy shall be transmitted at the same time to its Ministry of Justice; 
d that some or all requests for assistance shall be sent to it through channels other than those provided for in this article. 
9 Requests for mutual assistance and any other communications under this Convention or its Protocols may be forwarded through any electronic or other means of telecommunication provided that the requesting Party is prepared, upon request, to produce at any time a written record of it and the original. However, any Contracting State, may by a declaration addressed at any time to the Secretary General of the Council of Europe, establish the conditions under which it shall be willing to accept and execute requests received by electronic or other means of telecommunication.
