Meaning of International Disputes
An international dispute refers to a disagreement between States concerning questions of law, facts, rights, obligations, territory or other matters affecting their international relations.
International disputes may arise when one State makes a claim that another State rejects or when States disagree about the interpretation or application of international law.

For example, two neighbouring countries may disagree about the location of their international boundary. Similarly, States may have disputes concerning maritime rights, diplomatic relations, treaty obligations or the use of shared natural resources.
International disputes are generally classified into two categories.
Legal Disputes
Legal disputes involve disagreements concerning the interpretation or application of international law. They generally concern existing legal rights, duties or obligations.
Such disputes may involve treaty interpretation, territorial sovereignty, international responsibility or alleged violations of international conventions.

Legal disputes are particularly suitable for arbitration or judicial settlement because their resolution involves applying legal principles to established facts.
Political Disputes
Political disputes involve conflicting national interests, political demands, security concerns or diplomatic relationships.
Such disputes may not be resolved entirely through the application of legal rules. Negotiation, mediation and other diplomatic methods may therefore be more appropriate.
However, the distinction between legal and political disputes is not absolute. A single international dispute may contain both legal and political elements.
What Is the Peaceful Settlement of International Disputes?
The peaceful settlement of international disputes is the process through which States resolve disagreements without resorting to unlawful threats or the use of force.
It is a fundamental principle of international law and an essential objective of the United Nations.
The United Nations was established in 1945 following the Second World War. One of its central purposes was to maintain international peace and security by encouraging cooperation among States and providing mechanisms for resolving international conflicts.
Article 1(1) of the UN Charter identifies the maintenance of international peace and security as a principal purpose of the Organisation. It also recognises the need to bring about peaceful adjustment or settlement of international disputes in conformity with the principles of justice and international law.

The peaceful settlement principle seeks to prevent disagreements from developing into armed conflicts. It also protects the sovereignty of States while encouraging them to respect their international legal obligations.
Legal Framework for the Settlement of Disputes under the UN Charter
The UN Charter contains several provisions governing the peaceful settlement of international disputes. These provisions establish the obligations of States and define the responsibilities of different United Nations organs.
Article 2(3): Obligation to Settle Disputes Peacefully
Article 2(3) provides that all members shall settle their international disputes by peaceful means in such a manner that international peace and security, and justice, are not endangered.
This provision creates a general obligation to pursue peaceful methods of dispute resolution.
It does not require every dispute to be settled through a particular procedure. Instead, States generally retain the freedom to select an appropriate peaceful method, subject to applicable treaty obligations and other rules of international law.
Article 2(4): Prohibition on the Threat or Use of Force
Article 2(4) prohibits member States from threatening or using force against the territorial integrity or political independence of another State, or in any other manner inconsistent with the purposes of the United Nations.
This prohibition complements the obligation of peaceful dispute settlement.
The UN Charter nevertheless recognises specific exceptions within its legal framework, including the inherent right of individual or collective self-defence under Article 51 and enforcement action authorised by the Security Council under Chapter VII.
Chapter VI: Pacific Settlement of Disputes
Chapter VI, consisting of Articles 33 to 38, deals specifically with the peaceful settlement of disputes.

It establishes procedures through which States may resolve disagreements and authorises the Security Council to investigate disputes and recommend appropriate methods of settlement.
The emphasis under Chapter VI is primarily on peaceful cooperation, diplomatic engagement and recommendations rather than coercive enforcement.
Methods of Peaceful Settlement of International Disputes under Article 33
Article 33 of the UN Charter identifies the principal methods of peaceful settlement of international disputes. These methods are available to States whose disagreements may endanger international peace and security.
Negotiation
Negotiation is the process through which disputing States communicate directly to resolve their differences through mutual discussion and agreement.
It is one of the most commonly used methods of international dispute settlement because it allows States to retain control over the procedure and the final outcome.
Negotiations may take place through diplomatic representatives, foreign ministers, heads of government or specially appointed delegations.
For example, two countries involved in a boundary dispute may hold bilateral negotiations to determine a mutually acceptable border.
The success of negotiation depends upon the willingness of the parties to communicate, compromise and reach a mutually acceptable solution.
Enquiry
Enquiry is a method of dispute settlement that involves investigating disputed facts through an impartial body or commission.
International disagreements frequently arise because States present conflicting accounts of the same incident. An enquiry helps establish the relevant facts through the examination of evidence, documents and witness statements.
An international commission of enquiry may be constituted with the consent of the disputing States.
The commission generally prepares a report containing its factual findings. Such findings do not ordinarily constitute a binding settlement unless the parties have agreed otherwise.
Enquiry is particularly useful in disputes involving border incidents, alleged treaty violations or other disagreements concerning factual circumstances.
Mediation
Mediation is a peaceful dispute-settlement process in which an independent third party assists the disputing States in reaching a mutually acceptable agreement.
The mediator may be another State, an international organisation, a diplomatic representative or an individual accepted by the disputing parties.
Unlike a court or arbitral tribunal, a mediator does not ordinarily impose a binding decision.
The mediator may facilitate communication, identify areas of agreement and suggest possible solutions.
Mediation is particularly useful where direct negotiations have failed or diplomatic relations between the parties have deteriorated.
Conciliation
Conciliation is a structured method of international dispute settlement in which an independent commission examines a dispute and recommends possible settlement terms.
The conciliation commission may investigate relevant facts, consider legal arguments and evaluate the competing claims of the parties.
It then submits recommendations intended to provide a basis for agreement.
The recommendations are generally non-binding unless the parties have agreed to a different arrangement.
The principal difference between mediation and conciliation is that conciliation ordinarily involves a more formal examination of the dispute and the preparation of proposed settlement terms.
Arbitration
Arbitration is a method through which States submit an international dispute to an independent arbitral tribunal for a binding decision.
The tribunal derives its authority from the consent of the parties, usually expressed through an arbitration agreement or treaty.
The parties may agree upon the tribunal’s composition, applicable law and procedural rules.
Arbitration is particularly useful for disputes concerning territorial boundaries, treaty obligations and other legal questions. International arbitration is also used in cross-border commercial and investment disputes, although these are legally distinct from disputes exclusively between States. The distinction between international investment arbitration and international commercial arbitration is important in understanding the different legal frameworks.
Unlike negotiation or mediation, arbitration ordinarily results in a binding award that the parties are legally obliged to comply with.
Judicial Settlement
Judicial settlement refers to the resolution of international legal disputes through an established international court or tribunal.
The International Court of Justice is the principal judicial organ of the United Nations and plays a central role in this process.
Judicial settlement involves the application of international law to the facts and legal questions presented by the parties.
A judgment in a contentious case is binding upon the parties to that particular case.
However, the ICJ cannot automatically decide every international dispute. Its jurisdiction must be established through legally recognised forms of State consent.
Regional Agencies or Arrangements
Article 33 also recognises settlement through regional organisations or arrangements.
Regional bodies may help resolve disputes involving States within a particular geographical region.
Examples include the African Union, the Organization of American States and other regional institutions possessing relevant dispute-settlement mechanisms.
Regional mechanisms may be effective because neighbouring States often share geographical, historical and political concerns.
Other Peaceful Means
Article 33 permits States to adopt other peaceful methods of their choice.
One important example is good offices, where a third party helps disputing States establish communication or resume negotiations.
Unlike mediation, good offices primarily involve facilitating contact rather than actively proposing detailed settlement terms.
The flexibility provided by Article 33 allows States to adopt procedures suited to the circumstances of individual disputes.
Role of the Security Council in Settlement of International Disputes
The Security Council has primary responsibility for the maintenance of international peace and security under Article 24 of the UN Charter.
Chapter VI grants the Council several important powers concerning the peaceful settlement of disputes.
Article 33(2): Calling upon Parties to Settle Disputes
The Security Council may call upon parties to resolve their dispute through negotiation, mediation, arbitration or other peaceful methods.
This power allows the Council to encourage diplomatic engagement before disagreements develop into serious international conflicts.
Article 34: Investigation of Disputes
Article 34 authorises the Security Council to investigate disputes or situations that might lead to international friction.
The purpose of such an investigation is to determine whether continuation of the dispute or situation is likely to endanger international peace and security.
Investigations may assist the Council in understanding the circumstances and deciding whether recommendations or further action are necessary.
Article 35: Bringing Disputes before the United Nations
Under Article 35(1), any UN member State may bring a dispute or situation of the nature referred to in Article 34 to the attention of the Security Council or General Assembly.
Article 35(2) also permits a non-member State to bring a dispute to the attention of these organs, provided it is a party to the dispute and accepts the Charter’s peaceful-settlement obligations for that purpose.
Article 36: Recommendations for Settlement
Article 36 authorises the Security Council to recommend appropriate procedures or methods of adjustment at any stage of a dispute of the nature referred to in Article 33.
Under Article 36(3), the Council should consider that legal disputes ought, as a general rule, to be referred by the parties to the International Court of Justice in accordance with the Court’s Statute.
This does not independently create compulsory ICJ jurisdiction.
Article 37: Reference of Unresolved Disputes
Where parties fail to resolve a dispute through the methods mentioned in Article 33, Article 37(1) requires them to refer it to the Security Council.
If the Council considers that continuation of the dispute is likely to endanger international peace and security, it may take action under Article 36 or recommend appropriate terms of settlement.
Article 38: Settlement at the Request of Parties
Article 38 permits the Security Council to make recommendations for peaceful settlement where all parties to a dispute request such assistance.
The provision enables disputing States to seek the Council’s assistance even where they collectively prefer an internationally supported settlement process.
Recommendations made under Chapter VI are generally not treated as binding enforcement measures.
Role of the General Assembly in Dispute Settlement
The United Nations General Assembly provides an important forum for international discussion, cooperation and the peaceful adjustment of disputes.
Although it does not possess the same enforcement powers as the Security Council, it contributes to international dispute settlement through debate and recommendations.
Its principal functions include:
- Discussion of International Disputes: Under Article 10, the General Assembly may discuss questions or matters within the scope of the Charter and make recommendations, subject to the relevant limitations.
- Maintenance of International Peace: Article 11 permits the Assembly to discuss principles relating to international peace and security and make recommendations within its competence.
- Peaceful Adjustment of Situations: Article 14 authorises recommendations for the peaceful adjustment of situations likely to impair general welfare or friendly relations among nations, subject to Article 12.
- Development of International Cooperation: The Assembly may encourage dialogue and adopt resolutions expressing collective views on international disputes.
Article 12 places restrictions on General Assembly recommendations where the Security Council is exercising its functions concerning a dispute or situation. The application of this provision must also be understood in light of subsequent UN institutional practice.
General Assembly recommendations are ordinarily non-binding, but they may influence diplomatic negotiations and the development of international legal principles.
Role of the International Court of Justice in Dispute Settlement
The International Court of Justice, established under Article 92 of the UN Charter, is the principal judicial organ of the United Nations.
The Court functions under its Statute, which forms an integral part of the Charter.
It performs two principal functions.
Contentious Jurisdiction
Contentious jurisdiction involves deciding legal disputes submitted by States.
Only States may appear as parties in contentious proceedings before the ICJ.
The Court may exercise jurisdiction where the States concerned have accepted it through a special agreement, an applicable treaty provision, an optional-clause declaration under Article 36(2) of the ICJ Statute, or another recognised form of consent.
The judgment is binding only upon the parties and in respect of that particular case, as provided under Article 59 of the ICJ Statute.
Advisory Jurisdiction
Advisory jurisdiction involves providing legal opinions on questions referred by authorised UN organs and specialised agencies.
Under Article 96 of the Charter, the General Assembly and Security Council may request advisory opinions on legal questions.
Other authorised UN organs and specialised agencies may request opinions concerning legal questions arising within the scope of their activities.
Advisory opinions generally do not have the binding effect of contentious judgments, although they carry significant legal authority.
Enforcement of ICJ Judgments
Article 94(1) requires UN member States to comply with ICJ decisions in cases to which they are parties.
Where a party fails to fulfil obligations arising from a judgment, Article 94(2) permits the other party to approach the Security Council.
The Council may then make recommendations or decide upon appropriate measures to give effect to the judgment.
However, enforcement through the Security Council is not automatic.
Role of the UN Secretary-General in Peaceful Dispute Settlement
The Secretary-General plays an important diplomatic role in preventing and resolving international disputes.
The Secretary-General may facilitate negotiations, encourage communication and use good offices to help conflicting parties identify peaceful solutions.
Article 99 of the Charter authorises the Secretary-General to bring to the Security Council’s attention any matter that, in the Secretary-General’s opinion, may threaten international peace and security.
This power supports preventive diplomacy because it enables potential threats to be brought before the Council even before they develop into serious armed conflicts.
The Secretary-General may also appoint representatives or envoys to support peace negotiations and mediation initiatives.
Role of Regional Organisations under Chapter VIII
Chapter VIII of the UN Charter recognises the importance of regional arrangements in maintaining international peace and security.
Article 52 encourages member States participating in regional arrangements to make every effort to achieve peaceful settlement of local disputes through regional mechanisms before referring them to the Security Council.
The Security Council is also required to encourage the development of peaceful settlement through such arrangements.
However, regional enforcement action generally requires Security Council authorisation under Article 53, subject to the Charter’s provisions.
Regional organisations therefore supplement the United Nations dispute-settlement system rather than replace the authority of the Security Council.
Can the United Nations Take Enforcement Action against States?
Yes. The Security Council may adopt enforcement measures under international law where it determines that circumstances justify such action under Chapter VII.
Article 39 authorises the Council to determine whether a threat to peace, breach of peace or act of aggression exists.
Depending upon the circumstances, the Council may adopt measures including:
- Provisional Measures: Under Article 40, the Council may call upon parties to comply with provisional measures considered necessary or desirable to prevent the situation from worsening.
- Non-Military Measures: Article 41 permits measures not involving armed force, including economic sanctions, restrictions on communications and interruption of diplomatic relations.
- Military Measures: Article 42 authorises action by air, sea or land forces where the Council considers measures under Article 41 inadequate or likely to be inadequate.
Unlike recommendations generally made under Chapter VI, binding Security Council decisions adopted within its Charter powers create legal obligations for member States under Article 25.
However, Chapter VII primarily concerns the maintenance or restoration of international peace and security. It is not an ordinary substitute for negotiation, arbitration or judicial settlement.
Important Cases Relating to International Dispute Settlement
Corfu Channel Case (United Kingdom v. Albania), 1949
The Corfu Channel Case arose after British warships struck mines while passing through the Corfu Channel in October 1946.
The United Kingdom brought proceedings against Albania before the International Court of Justice.
In its judgment dated 9 April 1949, the Court held Albania internationally responsible for failing to notify the existence of mines in its territorial waters despite having knowledge of the danger.
The Court also found that the United Kingdom had violated Albanian sovereignty through its subsequent minesweeping operation in Albanian waters without consent.
Significance: The judgment demonstrates the ICJ’s role in determining international responsibility, applying the principle of territorial sovereignty and resolving legal disputes between States.
Jadhav Case (India v. Pakistan), 2019
The Jadhav Case concerned the arrest, detention and conviction of Indian national Kulbhushan Jadhav in Pakistan.
India instituted proceedings before the ICJ alleging violations of Article 36 of the Vienna Convention on Consular Relations, 1963.
In its judgment dated 17 July 2019, the Court held that Pakistan had breached its international obligations by failing to inform Jadhav of his consular rights and denying India appropriate consular access.
The Court directed Pakistan to provide effective review and reconsideration of the conviction and sentence, taking account of the violations of consular rights.
Significance: The case illustrates how States may use international judicial proceedings to resolve treaty disputes and establish responsibility for violations of international legal obligations.
Manila Declaration on the Peaceful Settlement of International Disputes, 1982
The Manila Declaration was adopted by the United Nations General Assembly through Resolution 37/10 on 15 November 1982.
It reaffirmed the principle that international disputes must be settled peacefully in accordance with the UN Charter.
The Declaration emphasises good faith, sovereign equality, the freedom of States to choose peaceful means and the importance of avoiding conduct that may aggravate international disputes.
It also encourages States to use available international institutions and procedures for dispute settlement.
Although the Declaration is not a treaty independently creating compulsory jurisdiction, it provides important guidance concerning peaceful dispute settlement under international law.
Difference between Peaceful Settlement and Enforcement Measures
| Basis | Peaceful Settlement | Enforcement Measures |
| Main Objective | Resolve disputes through peaceful procedures | Maintain or restore international peace and security |
| Legal Framework | Primarily Chapter VI | Primarily Chapter VII |
| Methods | Negotiation, mediation, arbitration and judicial settlement | Sanctions and other measures authorised under the Charter |
| Nature | Generally cooperative and based on diplomatic or legal procedures | May involve binding and coercive measures |
| Main UN Institution | Security Council, with roles for the ICJ and other organs | Security Council |
| Use of Force | Does not involve the use of armed force as a settlement method | May include authorised military action under Article 42 |
Limitations of the United Nations Dispute Settlement System
Despite its extensive legal framework, the United Nations system faces several limitations.
Dependence on State Cooperation
Many peaceful methods require States to participate voluntarily and negotiate in good faith. Where parties refuse to cooperate, achieving an agreed settlement becomes difficult.
Restrictions on ICJ Jurisdiction
The International Court of Justice cannot automatically exercise jurisdiction over every legal dispute. Its contentious jurisdiction depends upon legally recognised consent.
Security Council Veto
The five permanent members of the Security Council possess veto powers concerning non-procedural decisions under Article 27. This may prevent the Council from adopting particular measures even where a serious dispute threatens international peace.
Implementation Difficulties
The implementation of international judgments and recommendations may depend upon political willingness, diplomatic cooperation and available institutional mechanisms.
The ICJ does not possess an independent enforcement authority comparable to domestic law-enforcement institutions.
Political Differences between States
National security interests, international alliances and competing political priorities may influence diplomatic negotiations and the functioning of UN institutions.
Consequently, legal procedures alone may not always secure the immediate resolution of complex international disputes.
Conclusion
The settlement of international disputes under the United Nations Organisation is an essential part of the modern international legal system. The UN Charter establishes peaceful dispute settlement as a fundamental obligation and provides various diplomatic, judicial and institutional mechanisms for resolving disagreements between States.
Article 33 recognises negotiation, enquiry, mediation, conciliation, arbitration, judicial settlement and regional arrangements as important methods of peaceful dispute resolution. The Security Council, General Assembly, International Court of Justice and Secretary-General perform complementary functions within this framework.
Although limitations concerning State consent, political cooperation and enforcement continue to affect the effectiveness of the system, the United Nations provides a structured legal and diplomatic framework for addressing international disagreements without resorting to unlawful force.
