Role of the United Nations in Dispute Settlement

Introduction

The United Nations (UN) plays a central role in the peaceful settlement of international disputes. The UN Charter establishes peaceful settlement as one of the fundamental principles governing relations between States and provides a framework through which disputes can be negotiated, investigated, mediated, conciliated, arbitrated or judicially settled.

The UN does not operate through a single dispute-settlement mechanism. Different organs perform different functions depending upon the nature of the dispute and the relevant provisions of the Charter.

The UN’s role can broadly be understood through two interconnected functions:

• Peaceful settlement of disputes, primarily under Chapter VI; and
• Maintenance of international peace and security, including enforcement measures under Chapter VII where applicable.

The basic framework is:

Prevention → Investigation → Negotiation → Mediation → Conciliation → Arbitration / Judicial Settlement → Enforcement where necessary

Legal Basis

The principal legal foundations for the UN’s role in dispute settlement are found in the UN Charter.

Article 1(1)

One of the purposes of the United Nations is to maintain international peace and security and to bring about the peaceful adjustment or settlement of international disputes or situations which might lead to a breach of the peace.

Article 2(3)

Article 2(3) requires all UN Members to settle their international disputes by peaceful means in such a manner that international peace and security, and justice, are not endangered.

This is one of the fundamental principles governing international relations under the Charter.

Article 2(4)

Article 2(4) requires States to refrain from the threat or use of force against the territorial integrity or political independence of any State, or in any other manner inconsistent with the purposes of the United Nations.

The prohibition on the use of force reinforces the importance of peaceful dispute settlement.

Article 33 – Peaceful Means of Settlement

Article 33(1) is the central Charter provision concerning peaceful dispute settlement.

It provides that parties to a dispute likely to endanger international peace and security should seek a solution through:

• negotiation;
• enquiry;
• mediation;
• conciliation;
• arbitration;
• judicial settlement;
• resort to regional agencies or arrangements;
• other peaceful means of their own choice.

Therefore, Article 33 does not prescribe only one method. It provides a range of peaceful mechanisms from which appropriate means may be selected.

Important Point

Article 33 does not itself make every listed method compulsory in every dispute.

The precise obligation depends upon the Charter, the applicable treaty, the consent of the States and the circumstances of the dispute.

Chapter VI – Pacific Settlement of Disputes

Chapter VI of the UN Charter, particularly Articles 33–38, deals with the Pacific Settlement of Disputes.

It primarily provides mechanisms through which disputes can be addressed before they develop into threats to international peace and security.

The Security Council has an important role under this Chapter.

Role of the Security Council

The Security Council has primary responsibility under the UN Charter for the maintenance of international peace and security.

In relation to disputes, it may:

• encourage peaceful settlement;
• investigate disputes and situations;
• recommend appropriate procedures;
• recommend methods of settlement;
• recommend terms of settlement;
• facilitate negotiations;
• become involved when peaceful settlement fails;
• take enforcement measures when the conditions of Chapter VII are satisfied.

Its role therefore extends from diplomatic dispute settlement to collective security.

Article 34 – Investigation

Under Article 34, the Security Council may investigate:

• any dispute; or
• any situation which might lead to international friction or give rise to a dispute,

in order to determine whether its continuance is likely to endanger the maintenance of international peace and security.

This gives the Security Council an important investigative and preventive function.

Example

If two States give conflicting accounts of a serious border incident, the Security Council may investigate the situation to determine whether it threatens international peace and security.

Article 35 – Bringing Disputes Before the UN

Under Article 35, UN Members may bring disputes or situations of the type referred to in Article 34 to the attention of:

• the Security Council; or
• the General Assembly.

A non-member State may also bring such a dispute to the attention of the Security Council or General Assembly subject to the conditions provided by the Charter.

This provision allows international disputes to enter the UN’s institutional framework.

Article 36 – Recommendation of Procedures

Under Article 36, the Security Council may recommend appropriate procedures or methods of adjustment at any stage of a dispute.

The Council may take into account:

• procedures already adopted by the parties;
• procedures appropriate to the particular circumstances;
• the general principle that legal disputes should generally be referred by the parties to the International Court of Justice.

This provision connects the Security Council’s political role with judicial settlement.

Article 37 – Failure to Settle

Where parties to a dispute of the kind referred to in Article 33 fail to settle it by the peaceful means indicated there, they should refer the matter to the Security Council.

The Security Council may then recommend appropriate terms of settlement if it considers that the continuation of the dispute is likely to endanger international peace and security.

The Council is not acting as a court in this situation. Its role is primarily political and diplomatic.

Article 38 – Recommendation at the Request of Parties

Under Article 38, the Security Council may, if all parties to a dispute so request, make recommendations to the parties with a view to a peaceful settlement.

This provision emphasises the importance of the parties’ agreement in diplomatic settlement.

Role of the General Assembly

The General Assembly also contributes to peaceful dispute settlement.

Its role is primarily deliberative and recommendatory rather than adjudicatory.

Article 10

Under Article 10, the General Assembly may discuss matters within the scope of the Charter and make recommendations to UN Members or to the Security Council, subject to the Charter’s limitations.

Article 11

The General Assembly may consider general principles of cooperation in maintaining international peace and security, including principles relating to:

• disarmament;
• regulation of armaments;
• peaceful settlement of situations likely to impair friendly relations among nations.

Article 14

Article 14 allows the General Assembly to recommend measures for the peaceful adjustment of situations, regardless of origin, which it considers likely to impair the general welfare or friendly relations among nations.

Limitations of the General Assembly

The General Assembly does not generally possess the same enforcement powers as the Security Council.

Its resolutions are ordinarily recommendatory, although they can have considerable political and normative importance.

Therefore:

General Assembly → Discussion + Recommendation

Security Council → Investigation + Recommendation + Chapter VII powers where applicable

Role of the Secretary-General

The Secretary-General has an important role in preventing and resolving international disputes.

The Secretary-General may use:

• good offices;
• mediation;
• preventive diplomacy;
• diplomatic consultations;
• special representatives;
• special envoys.

The Secretary-General’s role is particularly important where direct negotiations between States have broken down.

Article 99 – Preventive Role

Article 99 provides that the Secretary-General may bring to the attention of the Security Council any matter which, in his opinion, may threaten the maintenance of international peace and security.

This gives the Secretary-General an important early-warning and preventive function.

Good Offices

The Secretary-General may use good offices to facilitate communication between parties.

This may involve:

• communicating with the parties;
• transmitting proposals or messages;
• encouraging dialogue;
• arranging meetings;
• helping restore diplomatic communication.

The Secretary-General does not normally impose a settlement.

Easy Memory Trick

Good Offices → Brings parties together

Mediation

The UN may also actively mediate international disputes.

A UN mediator or special envoy may:

• meet the parties;
• conduct separate consultations;
• identify common interests;
• propose possible solutions;
• encourage compromise;
• facilitate negotiations.

Easy Memory Trick

Mediation → Helps parties reach settlement

Inquiry and Fact-Finding

The UN can also assist in inquiry and fact-finding.

The purpose is to establish or clarify disputed facts.

A fact-finding mechanism may examine:

• documents;
• witness accounts;
• technical evidence;
• official reports;
• other relevant material.

Fact-finding can provide an objective factual basis for later negotiation, mediation or other forms of settlement.

Easy Memory Trick

Inquiry → Establishes facts

Conciliation

The UN framework also recognises conciliation as a peaceful method under Article 33.

Conciliation generally involves a third-party body examining:

• facts;
• legal issues;
• political considerations;

and then making recommendations for settlement.

The recommendations are generally not binding unless the applicable legal instrument provides otherwise.

Easy Memory Trick

Conciliation → Investigates + Evaluates + Recommends

Arbitration

The UN Charter recognises arbitration as a peaceful means under Article 33.

Arbitration involves submission of a dispute to an independent arbitral tribunal.

Unlike mediation or conciliation, the tribunal generally determines the dispute and issues a binding award, subject to the applicable agreement and legal framework.

The UN itself is not an arbitral tribunal, but the Charter encourages arbitration as one of the available peaceful means.

Judicial Settlement

The UN’s principal judicial institution is the International Court of Justice (ICJ).

The ICJ is the principal judicial organ of the United Nations.

It provides judicial settlement of legal disputes between States where the Court has jurisdiction.

The Court may deal with disputes concerning:

• treaties;
• territorial sovereignty;
• maritime boundaries;
• State responsibility;
• diplomatic relations;
• use of force;
• genocide;
• other questions of international law.

Jurisdiction of the ICJ

The ICJ does not automatically have jurisdiction over every dispute involving UN Members.

Its jurisdiction is based upon State consent.

Consent may arise through:

• special agreement;
• treaty provisions;
• declarations accepting compulsory jurisdiction under Article 36(2) of the ICJ Statute;
• other recognised bases of jurisdiction.

Thus:

UN membership ≠ automatic ICJ jurisdiction

ICJ Judgments

Where the ICJ has jurisdiction and decides a contentious case, its judgment is binding on the parties to that case.

Article 59 of the ICJ Statute provides that the decision of the Court has binding force between the parties and in respect of that particular case.

Therefore, an ICJ judgment is not automatically a universally binding precedent for every State.

Article 94 – Compliance with ICJ Judgments

Article 94(1) of the UN Charter provides that each UN Member undertakes to comply with the decision of the ICJ in any case to which it is a party.

Under Article 94(2), where a party fails to perform its obligations under a judgment, the other party may have recourse to the Security Council.

The Security Council may then make recommendations or decide upon measures, where appropriate.

Advisory Role of the ICJ

The ICJ also gives advisory opinions on legal questions referred to it by authorised UN organs and specialised agencies.

Article 96 of the UN Charter provides the basic framework for this advisory function.

Important Distinction

Contentious case → Judgment

Advisory proceeding → Advisory opinion

An advisory opinion does not generally have the same binding character as a judgment between States in a contentious case.

Regional Organisations

The UN Charter also recognises the role of regional arrangements and agencies.

Article 33 includes resort to regional agencies or arrangements among peaceful means.

Chapter VIII deals with regional arrangements.

Regional organisations can contribute to:

• mediation;
• negotiation;
• preventive diplomacy;
• peace processes;
• conflict management.

The Charter establishes a relationship between regional efforts and the Security Council.

Peacekeeping and Dispute Settlement

UN peacekeeping is not expressly listed as one of the methods in Article 33.

Nevertheless, peacekeeping operations can support peaceful settlement by:

• monitoring ceasefires;
• separating opposing forces;
• creating conditions for negotiations;
• supporting implementation of peace agreements;
• reducing the risk of renewed conflict.

Thus, peacekeeping is better understood as a supporting mechanism for maintaining peace and facilitating settlement, rather than as a traditional adjudicatory method.

Chapter VII – When Peaceful Settlement Fails

The UN’s role is not restricted to peaceful settlement.

Where a situation develops into a:

• threat to the peace;
• breach of the peace; or
• act of aggression,

the Security Council may act under Chapter VII.

This is different from the ordinary peaceful-settlement functions under Chapter VI.

Key Distinction

Chapter VI → Pacific settlement

Chapter VII → Collective security and enforcement

Article 39

Under Article 39, the Security Council determines whether there exists:

• a threat to the peace;
• breach of the peace; or
• act of aggression.

It may then make recommendations or decide upon measures under Articles 41 and 42.

Article 41 – Non-Forcible Measures

Under Article 41, the Security Council may decide upon measures not involving the use of armed force.

These may include:

• interruption of economic relations;
• interruption of communications;
• severance of diplomatic relations.

Such measures are commonly referred to as Security Council sanctions or other non-forcible measures.

Article 42 – Measures Involving Force

Where measures under Article 41 are inadequate, the Security Council may take action involving:

• air forces;
• sea forces;
• land forces,

as necessary to maintain or restore international peace and security, subject to the Charter framework.

This is a collective security mechanism, not ordinary dispute settlement through negotiation or adjudication.

Chapter VI vs Chapter VII

Chapter VI	Chapter VII
Pacific settlement of disputes	Collective security and enforcement
Articles 33–38	Articles 39–51
Negotiation, mediation, conciliation etc.	Sanctions and other enforcement measures
Primarily recommendatory	Can produce binding decisions where applicable
Seeks peaceful settlement	Addresses threats to peace, breaches and aggression

Relationship Between Chapter VI and Chapter VII

The two Chapters should not be treated as completely isolated.

A dispute may initially be addressed through:

Negotiation

↓

Mediation

↓

Fact-Finding

↓

Conciliation

↓

Arbitration / Judicial Settlement

If the situation deteriorates and threatens international peace and security:

↓

Security Council

↓

Chapter VII

↓

Collective measures

Thus, the UN system combines dispute settlement with collective security.

UN and Prevention of Disputes

The UN increasingly emphasises prevention rather than waiting for a dispute to become an armed conflict.

Preventive diplomacy may involve:

• early warning;
• good offices;
• mediation;
• fact-finding;
• diplomatic consultations;
• special envoys.

The objective is to address disputes before they escalate.

Importance of Peaceful Settlement

The UN’s dispute-settlement framework is important because it:

• discourages unilateral resort to force;
• provides institutional channels for diplomacy;
• facilitates communication between States;
• provides mechanisms for fact-finding;
• offers judicial settlement;
• supports regional dispute-resolution efforts;
• helps prevent escalation;
• provides collective responses to serious threats to peace.

Limitations of the UN’s Role

Despite its extensive framework, the UN’s ability to resolve every international dispute is limited.

State Consent

Many dispute-settlement mechanisms, especially international adjudication, depend upon State consent.

Political Nature of the Security Council

The Security Council is a political body rather than a court.

Its decisions can therefore be influenced by political considerations.

Veto Power

The five permanent members of the Security Council possess the power to veto substantive resolutions.

This can prevent or limit Council action.

Limited Enforcement

Although Chapter VII provides significant powers, implementation may depend upon political cooperation and practical circumstances.

Sovereignty of States

The UN operates within a system in which States remain the principal subjects of international law and retain significant sovereignty.

Jurisdictional Limitations

International courts and tribunals can only act within the jurisdiction granted to them.

Security Council vs ICJ

Security Council	ICJ
Political organ	Judicial organ
Maintains international peace and security	Determines legal disputes

Important Cases

Corfu Channel Case

The Corfu Channel case demonstrates the role of the ICJ in judicial settlement.

The dispute between the United Kingdom and Albania involved mines in the Corfu Channel and questions concerning State responsibility.

It is important for:

• State responsibility;
• territorial sovereignty;
• evidence;
• obligations concerning dangerous activities.

Nicaragua v United States

The Military and Paramilitary Activities in and against Nicaragua case is a major authority concerning:

• use of force;
• non-intervention;
• self-defence;
• customary international law.

It demonstrates the importance of judicial settlement in resolving significant disputes involving the use of force.

United States Diplomatic and Consular Staff in Tehran

The United States Diplomatic and Consular Staff in Tehran case illustrates judicial settlement concerning:

• diplomatic relations;
• consular relations;
• State responsibility;
• international obligations.

Bosnia and Herzegovina v Serbia and Montenegro

The Genocide Convention case demonstrates the ICJ’s role in determining questions of State responsibility under international law.

Lockerbie

The Lockerbie proceedings demonstrate the complex relationship between the ICJ and Security Council action, particularly where judicial proceedings intersect with measures taken under the UN Charter.

Conclusion

The United Nations has developed a broad institutional framework for the prevention and peaceful settlement of international disputes. The Charter encourages States to resolve disputes through peaceful methods and provides the UN with mechanisms for investigation, negotiation, mediation, conciliation, arbitration and judicial settlement.

The Security Council performs the central political role, while the General Assembly provides a broad deliberative and recommendatory forum. The Secretary-General contributes through good offices, mediation and preventive diplomacy, while the International Court of Justice provides judicial settlement of legal disputes within its jurisdiction.

Where peaceful settlement is insufficient and a situation threatens international peace and security, the Security Council may move from Chapter VI mechanisms to Chapter VII collective-security measures.

The complete framework can therefore be remembered as:

Article 2(3) → Peaceful Settlement

Article 33 → Peaceful Means

Security Council → Investigation + Recommendations

Secretary-General → Good Offices + Mediation

ICJ → Judicial Settlement

Chapter VI → Pacific Settlement

Chapter VII → Enforcement / Collective Security

Chapter VIII → Regional Arrangements
