Responsibility of States for Internationally Wrongful Acts

PART ONE
THE INTERNATIONALLY WRONGFUL ACT OF A STATE

CHAPTER I
GENERAL PRINCIPLES

Article l
Responsibility of a State for its internationally wrongful acts

Every internationally wrongful act of a State entails the international responsibility of that State.

Article 2
Elements of an internationally wrongful act of a State

There is an internationally wrongful act of a State when conduct consisting of an action or omission:

(a) Is attributable to the State under international law; and

(b) Constitutes a breach of an international obligation of the State.

Article 3
Characterization of an act of a State as internationally wrongful

The characterization of an act of a State as internationally wrongful is governed by international law. Such characterization is not affected by the characterization of the same act as lawful by internal law.

CHAPTER II
ATTRIBUTION OF CONDUCT TO A STATE

Article 4
Conduct of organs of a State

1. The conduct of any State organ shall be considered an act of that State under international law, whether the organ exercises legislative, executive, judicial or any other functions, whatever position it holds in the organization of the State, and whatever its character as an organ of the central Government or of a territorial unit of the State.

2. An organ includes any person or entity which has that status in accordance with the internal law of the State.

Article 5
Conduct of persons or entities exercising elements of governmental authority

The conduct of a person or entity which is not an organ of the State under article 4 but which is empowered by the law of that State to exercise elements of the governmental authority shall be
considered an act of the State under international law, provided the person or entity is acting in that capacity in the particular instance.

Article 6
Conduct of organs placed at the disposal of a State by another State

The conduct of an organ placed at the disposal of a State by another State shall be considered an act of the former State under international law if the organ is acting in the exercise of elements of the governmental authority of the State at whose disposal it is placed.

Article 7
Excess of authority or contravention of instructions

The conduct of an organ of a State or of a person or entity empowered to exercise elements of the governmental authority shall be considered an act of the State under international law if the organ, person or entity acts in that capacity, even if it exceeds its authority or contravenes instructions.

Article 8
Conduct directed or controlled by a State

The conduct of a person or group of persons shall be considered an act of a State under international law if the person or group of persons is in fact acting on the instructions of, or under the
direction or control of, that State in carrying out the conduct.

Article 9
Conduct carried out in the absence or default of the official authorities

The conduct of a person or group of persons shall be considered an act of a State under international law if the person or group of persons is in fact exercising elements of the governmental
authority in the absence or default of the official authorities and in circumstances such as to call for the exercise of those elements of authority.

Article 10
Conduct of an insurrectional or other movement

1. The conduct of an insurrectional movement which becomes the new Government of a State shall be considered an act of that State under international law.
2. The conduct of a movement, insurrectional or other, which succeeds in establishing a new State in part of the territory of a pre-existing State or in a territory under its administration shall be considered an act of the new State under international law.

3. This article is without prejudice to the attribution to a State of any conduct, however related to that of the movement concerned, which is to be considered an act of that State by virtue of articles 4 to 9.

Article 11
Conduct acknowledged and adopted by a State as its own

Conduct which is not attributable to a State under the preceding articles shall nevertheless be considered an act of that State under international law if and to the extent that the State acknowledges and adopts the conduct in question as its own.

CHAPTER III
BREACH OF AN INTERNATIONAL OBLIGATION

Article 12
Existence of a breach of an international obligation

There is a breach of an international obligation by a State when an act of that State is not in conformity with what is required of it by that obligation, regardless of its origin or character.

Article 13
International obligation in force for a State

An act of a State does not constitute a breach of an international obligation unless the State is bound by the obligation in question at the time the act occurs.

Article 14
Extension in time of the breach of an international obligation

1. The breach of an international obligation by an act of a State not having a continuing character occurs at the moment when the act is performed, even if its effects continue.

2. The breach of an international obligation by an act of a State having a continuing character extends over the entire period during which the act continues and remains not in conformity with the international obligation.

3. The breach of an international obligation requiring a State to prevent a given event occurs when the event occurs and extends over the entire period during which the event continues and remains not in conformity with that obligation.

Article 15
Breach consisting of a composite act

1. The breach of an international obligation by a State through a series of actions or omissions defined in aggregate as wrongful occurs when the action or omission occurs which, taken with the other actions or omissions, is sufficient to constitute the wrongful act.

2. In such a case, the breach extends over the entire period starting with the first of the actions or omissions of the series and lasts for as long as these actions or omissions are repeated and remain not in conformity with the international obligation.

CHAPTER IV
RESPONSIBILITY OF A STATE IN CONNECTION WITH THE ACT OF ANOTHER STATE

Article 16
Aid or assistance in the commission of an internationally wrongful act

A State which aids or assists another State in the commission of an internationally wrongful act by the latter is internationally responsible for doing so if:

(a) That State does so with knowledge of the circumstances of the internationally wrongful act; and

(b) The act would be internationally wrongful if committed by that State.

Article 17
Direction and control exercised over the commission of an internationally wrongful act

A State which directs and controls another State in the commission of an internationally wrongful act by the latter is internationally responsible for that act if:

(a) That State does so with knowledge of the circumstances of the internationally wrongful act; and

(b) The act would be internationally wrongful if committed by that State.

Article 18
Coercion of another State

A State which coerces another State to commit an act is internationally responsible for that act if:

(a) The act would, but for the coercion, be an internationally wrongful act of the coerced State; and

(b) The coercing State does so with knowledge of the circumstances of the act.

Article 19
Effect of this chapter

This chapter is without prejudice to the international responsibility, under other provisions of these articles, of the State which commits the act in question, or of any other State.

CHAPTER V
CIRCUMSTANCES PRECLUDING WRONGFULNESS

Article 20
Consent

Valid consent by a State to the commission of a given act by another State precludes the wrongfulness of that act in relation to the former State to the extent that the act remains within the limits of that consent.

Article 21
Self-defence

The wrongfulness of an act of a State is precluded if the act constitutes a lawful measure of self- defence taken in conformity with the Charter of the United Nations.

Article 22
Countermeasures in respect of an internationally wrongful act

The wrongfulness of an act of a State not in conformity with an international obligation towards another State is precluded if and to the extent that the act constitutes a countermeasure taken against the latter State in accordance with chapter II of part three.

Article 23
Force majeure

1. The wrongfulness of an act of a State not in conformity with an international obligation of that State is precluded if the act is due to force majeure, that is the occurrence of an irresistible force or of an unforeseen event, beyond the control of the State, making it materially impossible in the circumstances to perform the obligation.

2. Paragraph 1 does not apply if:

(a) The situation of force majeure is due, either alone or in combination with other factors, to the conduct of the State invoking it; or

(b) The State has assumed the risk of that situation occurring.

Article 24
Distress

1. The wrongfulness of an act of a State not in conformity with an international obligation of that State is precluded if the author of the act in question has no other reasonable way, in a situation of distress, of saving the author’s life or the lives of other persons entrusted to the author’s care.

2. Paragraph 1 does not apply if:

(a) The situation of distress is due, either alone or in combination with other factors, to the conduct of the State invoking it; or

(b) The act in question is likely to create a comparable or greater peril.

Article 25
Necessity

1. Necessity may not be invoked by a State as a ground for precluding the wrongfulness of an act not in conformity with an international obligation of that State unless the act:

(a) Is the only way for the State to safeguard an essential interest against a grave and imminent peril; and

(b) Does not seriously impair an essential interest of the State or States towards which the obligation exists, or of the international community as a whole.

2. In any case, necessity may not be invoked by a State as a ground for precluding wrongfulness if:

(a) The international obligation in question excludes the possibility of invoking necessity; or

(b) The State has contributed to the situation of necessity.

Article 26
Compliance with peremptory norms

Nothing in this chapter precludes the wrongfulness of any act of a State which is not in conformity with an obligation arising under a peremptory norm of general international law.

Article 27
Consequences of invoking a circumstance precluding wrongfulness

The invocation of a circumstance precluding wrongfulness in accordance with this chapter is without prejudice to:
(a) Compliance with the obligation in question, if and to the extent that the circumstance precluding wrongfulness no longer exists;

(b) The question of compensation for any material loss caused by the act in question.
