PART ONE. SCOPE AND DEFINITIONS
Article 1. Scope
The present articles apply to the effects of armed conflict on the relations of States under a treaty.
Article 2. Definitions
For the purposes of the present articles:
(a) “Treaty” means an international agreement concluded between States in written form and governed by international law, whether embodied in a single instrument or in two or more related instruments and whatever its particular designation, and includes treaties between States to which international organizations are also parties;
(b) “Armed conflict” means a situation in which there is resort to armed force between States or protracted resort to armed force between governmental authorities and organized armed groups.
PART TWO. PRINCIPLES
CHAPTER I. OPERATION OF TREATIES IN THE EVENT OF ARMED CONFLICTS
Article 3. General principle
The existence of an armed conflict does not ipso facto terminate or suspend the operation of treaties:
(a) As between States parties to the conflict;
(b) As between a State party to the conflict and a State that is not.
Article 4. Provisions on the operation of treaties
Where a treaty itself contains provisions on its operation in situations of armed conflict, those provisions shall apply.
Article 5. Application of rules on treaty interpretation
The rules of international law on treaty interpretation shall be applied to establish whether a treaty is susceptible to termination, withdrawal or suspension in the event of an armed conflict.
Article 6. Factors indicating whether a treaty is susceptible to termination, withdrawal or suspension
In order to ascertain whether a treaty is susceptible to termination, withdrawal or suspension in the event of an armed conflict, regard shall be had to all relevant factors, including:
(a) The nature of the treaty, in particular its subject matter, its object and purpose, its content and the number of parties to the treaty; and
(b) The characteristics of the armed conflict, such as its territorial extent, its scale and intensity, its duration and, in the case of non-international armed conflict, also the degree of outside involvement.
Article 7. Continued operation of treaties resulting from their subject matter
An indicative list of treaties, the subject matter of which involves an implication that they continue in operation, in whole or in part, during armed conflict, is to be found in the annex to the present articles.
CHAPTER II. OTHER PROVISIONS RELEVANT TO THE OPERATION OF TREATIES
Article 8. Conclusion of treaties during armed conflict
1. The existence of an armed conflict does not affect the capacity of a State party to that conflict to conclude treaties in accordance with international law.
2. States may conclude agreements involving termination or suspension of a treaty or part of a treaty that is operative between them during situations of armed conflict, or may agree to amend or modify the treaty.
Article 9. Notification of intention to terminate or withdraw from a treaty or to suspend its operation
1. A State intending to terminate or withdraw from a treaty to which it is a Party, or to suspend the operation of that treaty, as a consequence of an armed conflict shall notify the other State Party or States Parties to the treaty, or its depositary, of such intention.
2. The notification takes effect upon receipt by the other State Party or States Parties, unless it provides for a subsequent date.
3. Nothing in the preceding paragraphs shall affect the right of a Party to object within a rea- sonable time, in accordance with the terms of the treaty or other applicable rules of international law, to the termination of or withdrawal from the treaty, or suspension of its operation.
4. If an objection has been raised in accordance with paragraph 3, the States concerned shall seek a solution through the means indicated in Article 33 of the Charter of the United Nations.
5. Nothing in the preceding paragraphs shall affect the rights or obligations of States with regard to the settlement of disputes insofar as they have remained applicable.
Article 10. Obligations imposed by international law independently of a treaty
The termination of or the withdrawal from a treaty, or the suspension of its operation, as a consequence of an armed conflict, shall not impair in any way the duty of any State to fulfil any obligation embodied in the treaty to which it would be subject under international law independently of that treaty.
Article 11. Separability of treaty provisions
Termination, withdrawal from or suspension of the operation of a treaty as a consequence of an armed conflict shall, unless the treaty otherwise provides or the Parties otherwise agree, take effect with respect to the whole treaty except where:
(a) The treaty contains clauses that are separable from the remainder of the treaty with regard to their application;
(b) It appears from the treaty or is otherwise established that acceptance of those clauses was not an essential basis of the consent of the other Party or Parties to be bound by the treaty as a whole; and
(c) Continued performance of the remainder of the treaty would not be unjust.
Article 12. Loss of the right to terminate or withdraw from a treaty or to suspend its operation
A State may no longer terminate or withdraw from a treaty or suspend its operation as a con- sequence of an armed conflict if, after becoming aware of the facts:
(a) It shall have expressly agreed that the treaty remains in force or continues in operation; or
(b) It must by reason of its conduct be considered as having acquiesced in the continued operation of the treaty or in its maintenance in force.
Article 13. Revival or resumption of treaty relations subsequent to an armed conflict
1. Subsequent to an armed conflict, the States Parties may regulate, on the basis of agreement, the revival of treaties terminated or suspended as a consequence of the armed conflict.
2. The resumption of the operation of a treaty suspended as a consequence of an armed conflict shall be determined in accordance with the factors referred to in article 6.
PART THREE. MISCELLANEOUS
Article 14. Effect of the exercise of the right to self-defence on a treaty
A State exercising its inherent right of individual or collective self-defence in accordance with the Charter of the United Nations is entitled to suspend in whole or in part the operation of a treaty to which it is a Party insofar as that operation is incompatible with the exercise of that right.
Article 15. Prohibition of benefit to an aggressor State
A State committing aggression within the meaning of the Charter of the United Nations and resolution 3314 (XXIX) of the General Assembly of the United Nations shall not terminate or with- draw from a treaty or suspend its operation as a consequence of an armed conflict that results from the act of aggression if the effect would be to the benefit of that State.
Article 16. Decisions of the Security Council
The present articles are without prejudice to relevant decisions taken by the Security Council in accordance with the Charter of the United Nations.
Article 17. Rights and duties arising from the laws of neutrality
The present articles are without prejudice to the rights and duties of States arising from the laws of neutrality.
