United Nations Convention on Jurisdictional Immunities of States and Their Property

The States Parties to the present Convention,

Considering that the jurisdictional immunities of States and their property are generally accepted as a principle of customary international law, 

Having in mind the principles of international law embodied in the Charter of the United Nations,

Believing that an international convention on the jurisdictional immunities of States and their property would enhance the rule of law and legal certainty, particularly in dealings of States with natural or juridical persons, and would contribute to the codification and development of international law and the harmonization of practice in this area,

Taking into account developments in State practice with regard to the jurisdictional immunities of States and their property,

Affirming that the rules of customary international law continue to govern matters not regulated by the provisions of the present Convention, 

Have agreed as follows: 

PART I
INTRODUCTION

Article 1
Scope of the present Convention

The present Convention applies to the immunity of a State and its property from the jurisdiction of the courts of another State. 

Article 2
Use of terms

1. For the purposes of the present Convention: 

(a) “court” means any organ of a State, however named, entitled to exercise judicial functions;
(b) “State” means:
(i) the State and its various organs of government;
(ii) constituent units of a federal State or political subdivisions of the State, which are
entitled to perform acts in the exercise of sovereign authority, and are acting in that capacity;
(iii) agencies or instrumentalities of the State or other entities, to the extent that they are entitled to perform and are actually performing acts in the exercise of sovereign authority of the State;
(iv) representatives of the State acting in that capacity;
(c) “commercial transaction” means:
(i) any commercial contract or transaction for the sale of goods or supply of services;
(ii) any contract for a loan or other transaction of a financial nature, including any
  	obligation of guarantee or of indemnity in respect of any such loan or transaction;
(iii) any other contract or transaction of a commercial, industrial, trading or professional nature, but not including a contract of employment of persons.

2. In determining whether a contract or transaction is a “commercial transaction” under paragraph 1 (c), reference should be made primarily to the nature of the contract or transaction, but its purpose should also be taken into account if the parties to the contract or transaction have so agreed, or if in the practice of the State of the forum, that purpose is relevant to determining the non-commercial character of the contract or transaction. 

3. The provisions of paragraphs 1 and 2 regarding the use of terms in the present Convention are without prejudice to the use of those terms or to the meanings which may be given to them in other international instruments or in the internal law of any State.

Article 3
Privileges and immunities not affected by the present Convention

1. The present Convention is without prejudice to the privileges and immunities enjoyed by a
State under international law in relation to the exercise of the functions of:

(a) its diplomatic missions, consular posts, special missions, missions to international organizations or delegations to organs of international organizations or to international conferences; and

(b) persons connected with them.

2. The present Convention is without prejudice to privileges and immunities accorded under international law to heads of State ratione personae.

3. The present Convention is without prejudice to the immunities enjoyed by a State under international law with respect to aircraft or space objects owned or operated by a State.

Article 4
Non-retroactivity of the present Convention

Without prejudice to the application of any rules set forth in the present Convention to which jurisdictional immunities of States and their property are subject under international law independently of the present Convention, the present Convention shall not apply to any question of jurisdictional immunities of States or their property arising in a proceeding instituted against a State before a court of another State prior to the entry into force of the present Convention for the States concerned.

PART II
GENERAL PRINCIPLES

Article 5
State imunity

A State enjoys immunity, in respect of itself and its property, from the jurisdiction of the courts of another State subject to the provisions of the present Convention.

Article 6
Modalities for giving effect to State imunity

1. A State shall give effect to State immunity under article 5 by refraining from exercising jurisdiction in a proceeding before its courts against another State and to that end shall ensure that its courts determine on their own initiative that the immunity of that other State under article 5 is respected.

2. A proceeding before a court of a State shall be considered to have been instituted against another State if that other State:

(a) is named as a party to that proceeding; or

(b) is not named as a party to the proceeding but the proceeding in effect seeks to affect the property, rights, interests or activities of that other State.

Article 7
Express consent to exercise of jurisdiction

1. A State cannot invoke immunity from jurisdiction in a proceeding before a court of another
State with regard to a matter or case if it has expressly consented to the exercise of jurisdiction by the court with regard to the matter or case:

(a) by international agreement;

(b) in a written contract; or

(c) by a declaration before the court or by a written communication in a specific proceeding.

2. Agreement by a State for the application of the law of another State shall not be interpreted as consent to the exercise of jurisdiction by the courts of that other State.

Article 8
Effect of participation in a proceeding before a court

1. A State cannot invoke immunity from jurisdiction in a proceeding before a court of another
State if it has:

(a) itself instituted the proceeding; or

(b) intervened in the proceeding or taken any other step relating to the merits. However, if the State satisfies the court that it could not have acquired knowledge of facts on which a claim to immunity can be based until after it took such a step, it can claim immunity based on those facts, provided it does so at the earliest possible moment.

2. A State shall not be considered to have consented to the exercise of jurisdiction by a court of another State if it intervenes in a proceeding or takes any other step for the sole purpose of:

(a) invoking immunity; or

(b) asserting a right or interest in property at issue in the proceeding.

3. The appearance of a representative of a State before a court of another State as a witness shall not be interpreted as consent by the former State to the exercise of jurisdiction by the court.

4. Failure on the part of a State to enter an appearance in a proceeding before a court of another State shall not be interpreted as consent by the former State to the exercise of jurisdiction by the court.

Article 9
Counterclaims

1. A State instituting a proceeding before a court of another State cannot invoke immunity from the jurisdiction of the court in respect of any counterclaim arising out of the same legal relationship or facts as the principal claim.

2. A State intervening to present a claim in a proceeding before a court of another State cannot invoke immunity from the jurisdiction of the court in respect of any counterclaim arising out of the same legal relationship or facts as the claim presented by the State.

3. A State making a counterclaim in a proceeding instituted against it before a court of another
State cannot invoke immunity from the jurisdiction of the court in respect of the principal claim.

PART III
PROCEEDINGS IN WHICH STATE IMMUNITY CANNOT BE INVOKED

Article 10
Commercial transactions

1. If a State engages in a commercial transaction with a foreign natural or juridical person and, by virtue of the applicable rules of private international law, differences relating to the commercial transaction fall within the jurisdiction of a court of another State, the State cannot invoke immunity from that jurisdiction in a proceeding arising out of that commercial transaction. 

2. Paragraph 1 does not apply:

(a) in the case of a commercial transaction between States; or

(b) if the parties to the commercial transaction have expressly agreed otherwise.

(a) suing or being sued; and

(b) acquiring, owning or possessing and disposing of property, including property which that State has authorized it to operate or manage, is involved in a proceeding which relates to a commercial transaction in which that entity is engaged, the immunity from jurisdiction enjoyed by that State shall not be affected.

Article 11
Contracts of employment

1. Unless otherwise agreed between the States concerned, a State cannot invoke immunity from jurisdiction before a court of another State which is otherwise competent in a proceeding which relates to a contract of employment between the State and an individual for work performed or to be performed, in whole or in part, in the territory of that other State.

(d) the subject-matter of the proceeding is the dismissal or termination of employment of an
individual and, as determined by the head of State, the head of Government or the Minister for Foreign Affairs of the employer State, such a proceeding would interfere with the security interests of that State;

(e) the employee is a national of the employer State at the time when the proceeding is instituted, unless this person has the permanent residence in the State of the forum; or

(f) the employer State and the employee have otherwise agreed in writing, subject to any
considerations of public policy conferring on the courts of the State of the forum exclusive jurisdiction by reason of the subject-matter of the proceeding.

Article 12
Personal injuries and damage to property

Unless otherwise agreed between the States concerned, a State cannot invoke immunity from jurisdiction before a court of another State which is otherwise competent in a proceeding which relates to pecuniary compensation for death or injury to the person, or damage to or loss of tangible property, caused by an act or omission which is alleged to be attributable to the State, if the act or omission occurred in whole or in part in the territory of that other State and if the author of the act or omission was present in that territory at the time of the act or omission.

Article 13
Ownership, possession and use of property

Unless otherwise agreed between the States concerned, a State cannot invoke immunity from

1. A State cannot invoke immunity from jurisdiction before a court of another State which is otherwise competent in a proceeding which relates to its participation in a company or other collective body, whether incorporated or unincorporated, being a proceeding concerning the relationship between the State and the body or the other participants therein, provided that the body:

(a) has participants other than States or international organizations; and

(b) is incorporated or constituted under the law of the State of the forum or has its seat or principal place of business in that State.

2. A State can, however, invoke immunity from jurisdiction in such a proceeding if the States concerned have so agreed or if the parties to the dispute have so provided by an agreement in writing or if the instrument establishing or regulating the body in question contains provisions to that effect.

Article 16
Ships owned or operated by a State

1. Unless otherwise agreed between the States concerned, a State which owns or operates a ship cannot invoke immunity from jurisdiction before a court of another State which is otherwise competent in a proceeding which relates to the operation of that ship if, at the time the cause of action arose, the ship was used for other than government non-commercial purposes.

2. Paragraph 1 does not apply to warships, or naval auxiliaries, nor does it apply to other vessels owned or operated by a State and used, for the time being, only on government non-commercial service.

3. Unless otherwise agreed between the States concerned, a State cannot invoke immunity from jurisdiction before a court of another State which is otherwise competent in a proceeding which relates to the carriage of cargo on board a ship owned or operated by that State if, at the time the cause of action arose, the ship was used for other than government non-commercial purposes.

5. States may plead all measures of defence, prescription and limitation of liability which are
available to private ships and cargoes and their owners.

If in a proceeding there arises a question relating to the government and non-commercial character of a ship owned or operated by a State or cargo owned by a State, a certificate signed by a diplomatic representative or other competent authority of that State and communicated to the court shall serve as evidence of the character of that ship or cargo.

Article 17

Annex to the Convention

Understandings with respect to certain provisions of the Convention

The present annex is for the purpose of setting out understandings relating to the provisions concerned.

With respect to article 10

The term “immunity” in article 10 is to be understood in the context of the present Convention as a whole.

Article 10, paragraph 3, does not prejudge the question of “piercing the corporate veil”, questions relating to a situation where a State entity has deliberately misrepresented its financial position or subsequently reduced its assets to avoid satisfying a claim, or other related issues.

With respect to article 11

The reference in article 11, paragraph 2 (d), to the “security interests” of the employer State is intended primarily to address matters of national security and the security of diplomatic missions and consular posts.

Under article 41 of the 1961 Vienna Convention on Diplomatic Relations and article 55 of the 1963 Vienna Convention on Consular Relations, all persons referred to in those articles have the duty to respect the laws and regulations, including labour laws, of the host country. At the same time, under article 38 of the 1961 Vienna Convention on Diplomatic Relations and article 71 of the 1963 Vienna Convention on Consular Relations, the receiving State has a duty to exercise its jurisdiction in such a manner as not to interfere unduly with the performance of the functions of the mission or the consular post.

With respect to articles 13 and 14

The expression “determination” is used to refer not only to the ascertainment or verification of the existence of the rights protected, but also to the evaluation or assessment of the substance, including content, scope and extent, of such rights.

With respect to article 17

The expression “commercial transaction” includes investment matters.

With respect to article 19

The expression “entity” in subparagraph (c) means the State as an independent legal personality, a constituent unit of a federal State, a subdivision of a State, an agency or instrumentality of a State or other entity, which enjoys independent legal personality.

The words “property that has a connection with the entity” in subparagraph (c) are to be understood as broader than ownership or possession.

Article 19 does not prejudge the question of “piercing the corporate veil”, questions relating to a situation where a State entity has deliberately misrepresented its financial position or subsequently reduced its assets to avoid satisfying a claim,
