The member States of the Council of Europe, signatories hereto,
Having regard to the Convention for the Protection of Human Rights and Fundamental Freedoms, signed at Rome on 4 November 1950 (hereinafter referred to as "the Convention");
Recalling the European Agreement relating to Persons Participating in Proceedings of the European Commission and Court of Human Rights, signed at London on 6 May 1969;
Having regard to Protocol No. 11 to the Convention, restructuring the control machinery established thereby, signed at Strasbourg on 11 May 1994 (hereinafter referred to as "Protocol No. 11 to the Convention"), which establishes a permanent European Court of Human Rights (hereinafter referred to as "the Court") to replace the European Commission and Court of Human Rights;
Considering, in the light of this development, that it is advisable for the better fulfilment of the purposes of the Convention that persons taking part in proceedings before the Court be accorded certain immunities and facilities by a new Agreement, the European Agreement relating to Persons Participating in Proceedings of the European Court of Human Rights (hereinafter referred to as "this Agreement"),
Have agreed as follows:

Article 1

1. The persons to whom this Agreement applies are:
   1. any persons taking part in proceedings instituted before the Court as parties, their representatives and advisers;
   2. witnesses and experts called upon by the Court and other persons invited by the President of the Court to take part in proceedings.
2. For the purposes of this Agreement, the term "Court" shall include committees, chambers, a panel of the Grand Chamber, the Grand Chamber and the judges. The term "taking part in proceedings" shall include making communications with a view to a complaint against a State Party to the Convention.
3. If in the course of the exercise by the Committee of Ministers of its functions under Article 46, paragraph 2, of the Convention, any person mentioned in paragraph 1 above is called upon to appear before, or to submit written statements to the Committee of Ministers, the provisions of this Agreement shall apply in relation to him.

1. The persons referred to in paragraph 1 of Article 1 of this Agreement shall have immunity from legal process in respect of oral or written statements made, or documents or other evidence submitted by them before or to the Court.
2. This immunity does not apply to communication outside the Court of any such statements, documents or evidence submitted to the Court.

1. The Contracting Parties shall respect the right of the persons referred to in paragraph 1 of Article 1 of this Agreement to correspond freely with the Court.
2. As regards persons under detention, the exercise of this right shall in particular imply that:
   1. their correspondence shall be despatched and delivered without undue delay and without alteration;
   2. such persons shall not be subject to disciplinary measures in any form on account of any communication sent through the proper channels to the Court;
   3. such persons shall have the right to correspond, and consult out of hearing of other persons, with a lawyer qualified to appear before the courts of the country where they are detained in regard to an application to the Court, or any proceedings resulting therefrom.
3. In application of the preceding paragraphs, there shall be no interference by a public authority except such as is in accordance with the law and is necessary in a democratic society in the interests of national security, for the detection or prosecution of a criminal offence or for the protection of health.

1. Immunities and facilities are accorded to the persons referred to in paragraph 1 of Article 1 of this Agreement solely in order to ensure for them the freedom of speech and the independence necessary for the discharge of their functions, tasks or duties, or the exercise of their rights in relation to the Court.
2.  
   1. The Court shall alone be competent to waive, in whole or in part, the immunity provided for in paragraph 1 of Article 2 of this Agreement; it has not only the right but the duty to waive immunity in any case where, in its opinion, such immunity would impede the course of justice and waiver in whole or in part would not prejudice the purpose defined in paragraph 1 of this Article.
   2. The immunity may be waived by the Court, either ex officio or at the request of any Contracting Party or of any person concerned.
   3. Decisions waiving immunity or refusing the waiver shall be accompanied by a statement of reasons.
3. If a Contracting Party certifies that waiver of the immunity provided for in paragraph 1 of Article 2 of this Agreement is necessary for the purpose of proceedings in respect of an offence against national security, the Court shall waive immunity to the extent specified in the certificate.
4. In the event of the discovery of a fact which might, by its nature, have a decisive influence and which at the time of the decision refusing waiver of immunity was unknown to the author of the request, the latter may make a new request to the Court.

Nothing in this Agreement shall be construed as limiting or derogating from any of the obligations assumed by the Contracting Parties under the Convention or its protocols.

1. This Agreement shall be open for signature by the member States of the Council of Europe, which may express their consent to be bound by:
   1. signature without reservation as to ratification, acceptance or approval; or
   2. signature, subject to ratification, acceptance or approval, followed by ratification, acceptance or approval.
2. Instruments of ratification, acceptance or approval shall be deposited with the Secretary General of the Council of Europe.

1. This Agreement shall enter into force on the first day of the month following the expiration of a period of one month after the date on which ten member States of the Council of Europe have expressed their consent to be bound by the Agreement in accordance with the provisions of Article 7 or on the date of entry into force of Protocol No. 11 to the Convention, whichever is the later.
2. In respect of any member State which subsequently expresses its consent to be bound by it, this Agreement shall enter into force on the first day of the month following the expiration of a period of one month after the date of such signature or of the deposit of the instrument of ratification, acceptance or approval.

1. Any Contracting State may, when depositing its instrument of ratification, acceptance or approval or at any later date, by declaration addressed to the Secretary General of the Council of Europe, extend this Agreement to any territory or territories specified in the declaration and for whose international relations it is responsible or on whose behalf it is authorised to give undertakings.
2. This Agreement shall enter into force for any territory or territories specified in a declaration made pursuant to paragraph 1 on the first day of the month following the expiration of one month after the date of receipt of the declaration by the Secretary General.

1. This Agreement shall remain in force indefinitely.
2. Any Contracting Party may, insofar as it is concerned, denounce this Agreement by means of a notification addressed to the Secretary General of the Council of Europe.
3. Such denunciation shall take effect six months after the date of receipt by the Secretary General of such notification. Such denunciation shall not have the effect of releasing the Contracting Parties concerned from any obligation which may have arisen under this Agreement in relation to any person referred to in paragraph 1 of Article 1.

1. any signature;
2. the deposit of any instrument of ratification, acceptance or approval;
3. any date of entry into force of this Agreement in accordance with Articles 8 and 9 thereof;
