UN Secretariat – Functions, Secretary-General, Articles and Importance

Introduction

The United Nations Secretariat is one of the six principal organs of the United Nations. It is the administrative and operational machinery of the UN and performs the day-to-day work necessary for carrying out the purposes and decisions of the organisation.

The Secretariat is headed by the Secretary-General, who is the chief administrative officer of the United Nations.

Its work covers a very wide range of activities, including:

• peace and security;
• mediation and preventive diplomacy;
• human rights;
• economic and social affairs;
• humanitarian assistance;
• international law;
• administration and finance;
• coordination of UN programmes and operations.

The Secretariat is therefore not simply an office for clerical work. It performs important political, diplomatic, legal, administrative and operational functions.

Legal Basis

The principal Charter provisions concerning the Secretariat are contained in Chapter XV of the UN Charter.

Important provisions include:

• Article 97 – establishes the Secretariat and provides for the Secretary-General.
• Article 98 – sets out the Secretary-General’s functions.
• Article 99 – gives the Secretary-General authority to bring matters threatening international peace and security to the attention of the Security Council.
• Article 100 – establishes the independence of the Secretary-General and Secretariat personnel.
• Article 101 – deals with appointment of staff and conditions of service.

Therefore:

Chapter XV → Articles 97–101 → UN Secretariat

Composition of the Secretariat

The Secretariat consists of:

Secretary-General

Under-Secretaries-General

Assistant Secretaries-General

International civil servants and other personnel

The Secretariat operates through numerous departments, offices and specialised units.

Secretary-General

The Secretary-General is the head of the Secretariat.

Article 97 provides that the Secretary-General is appointed by the General Assembly upon the recommendation of the Security Council.

This means both organs have a role:

Security Council → Recommendation

↓

General Assembly → Appointment

The permanent members of the Security Council therefore have substantial influence over the selection process.

Secretary-General as Chief Administrative Officer

Article 97 describes the Secretary-General as the “chief administrative officer” of the organisation.

However, the practical role of the office extends significantly beyond ordinary administration.

The Secretary-General also performs:

• diplomatic functions;
• political functions;
• preventive diplomacy;
• mediation;
• good offices;
• reporting;
• coordination;
• representation of the UN.

Thus, the Secretary-General has both an administrative role and an important international political role.

Functions under Article 98

Article 98 provides that the Secretary-General:

• acts in that capacity in all meetings of the General Assembly, Security Council, Economic and Social Council and Trusteeship Council;
• performs other functions entrusted to him by those organs;
• makes an annual report to the General Assembly on the work of the organisation.

Therefore, the Secretary-General acts as an important link between the different organs of the UN.

Article 99 – Independent Political Role

Article 99 is one of the most important provisions concerning the Secretary-General.

It 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 provision gives the Secretary-General an important political and preventive-diplomacy function.

The significance is that the Secretary-General does not always have to wait for a Member State or another UN organ to raise an issue.

The Secretary-General can independently draw the Security Council’s attention to a matter.

Article 100 – Independence of Secretariat

Article 100 is fundamental to the international character of the Secretariat.

The Secretary-General and Secretariat staff must not:

• seek or receive instructions from any government or outside authority;
• act in a manner incompatible with their international responsibilities.

Member States must also respect the exclusively international character of these responsibilities.

This establishes the principle of international civil service independence.

Article 101 – Appointment of Staff

Article 101 deals with appointment of Secretariat staff.

The staff are appointed by the Secretary-General under regulations established by the General Assembly.

The paramount consideration in employment is:

Efficiency + Competence + Integrity

The Charter also requires due regard to the importance of recruiting staff on as wide a geographical basis as possible.

International Civil Servants

Secretariat personnel are international civil servants.

They do not act as representatives of their individual States.

For example:

Indian national working for UN Secretariat

≠

Representative of India

The individual owes professional responsibilities to the United Nations, not to the government of the State of nationality.

Principle of International Character

The international character of the Secretariat is essential to the functioning of the UN.

A Secretariat controlled directly by individual governments would undermine the independence and effectiveness of the organisation.

Therefore:

National nationality

↓

International appointment

↓

International responsibilities

Functions of the UN Secretariat

The Secretariat performs several major functions.

Administrative Functions

It provides administrative support to the UN’s principal organs and numerous programmes and operations.

This includes:

• meetings;
• documentation;
• records;
• personnel;
• budgeting support;
• logistics;
• communication.

Political Functions

The Secretariat supports international political processes involving:

• conflict prevention;
• mediation;
• peace negotiations;
• political missions;
• preventive diplomacy.

Peace and Security Functions

The Secretariat supports:

• Security Council activities;
• peacekeeping operations;
• political missions;
• sanctions implementation support;
• conflict prevention.

Diplomatic Functions

The Secretary-General can act as:

• mediator;
• facilitator;
• intermediary;
• provider of good offices.

The office can therefore assist States and other parties in resolving international disputes.

Humanitarian Functions

The Secretariat works with the wider UN system on:

• humanitarian crises;
• displacement;
• emergency response;
• disaster situations;
• humanitarian coordination.

Human Rights Functions

The Secretariat supports UN human-rights mechanisms and activities.

The Office of the High Commissioner for Human Rights (OHCHR) is part of the UN Secretariat.

International Law Functions

The Secretariat also plays an important role in the development and codification of international law.

The Office of Legal Affairs (OLA) provides legal services to the UN.

The International Law Commission (ILC), while not itself a Secretariat department, is a subsidiary body established by the General Assembly and works closely within the UN institutional framework.

Departments and Offices

The Secretariat contains numerous departments and offices dealing with different areas.

Important examples include:

Department of Political and Peacebuilding Affairs

Works on:

• conflict prevention;
• mediation;
• peacebuilding;
• political missions.

Department of Peace Operations

Provides support for:

• UN peacekeeping operations;
• military and police components;
• mission planning;
• operational coordination.

Office of Legal Affairs

Provides legal advice and services to the UN and its organs.

It is important in:

• interpretation of Charter provisions;
• treaty matters;
• institutional legal questions;
• international legal affairs.

Office for the Coordination of Humanitarian Affairs

Known as OCHA, it supports coordination of humanitarian responses.

Office of the High Commissioner for Human Rights

Known as OHCHR, it supports the UN human-rights system.

Secretary-General and Peacekeeping

The Secretary-General plays an important role in UN peacekeeping.

The Secretary-General may:

• recommend or facilitate missions;
• appoint mission leadership;
• oversee Secretariat support;
• report to the Security Council;
• engage politically with parties;
• conduct diplomacy.

However, the Secretary-General does not possess unlimited independent authority to deploy UN forces.

Peacekeeping mandates generally depend upon decisions of the competent UN organs, particularly the Security Council.

Secretary-General and Mediation

The Secretary-General frequently uses:

• good offices;
• mediation;
• preventive diplomacy;
• special envoys.

The purpose is to prevent disputes from escalating into armed conflict or to help parties reach political settlements.

Secretary-General and Preventive Diplomacy

Preventive diplomacy means diplomatic efforts designed to prevent:

• disputes from arising;
• disputes from escalating;
• existing conflicts from becoming more violent.

Article 99 provides an important constitutional basis for the Secretary-General’s independent role in this field.

Secretariat and General Assembly

The Secretariat provides administrative and substantive support to the General Assembly.

It assists with:

• preparation of documents;
• meetings;
• reports;
• interpretation and translation;
• implementation of decisions;
• institutional coordination.

The Secretary-General also submits an annual report to the General Assembly under Article 98.

Secretariat and Security Council

The Secretariat provides extensive support to the Security Council.

It assists with:

• Council meetings;
• documentation;
• briefings;
• reporting;
• sanctions-related work;
• peacekeeping;
• political missions.

The Secretary-General can also use Article 99 to bring matters to the Council’s attention.

Secretariat and ECOSOC

The Secretariat provides administrative and substantive support to the Economic and Social Council and its subsidiary bodies.

Its work includes areas such as:

• economic development;
• social development;
• sustainable development;
• statistics;
• international cooperation.

Secretariat and Trusteeship Council

The Secretariat historically supported the Trusteeship Council in carrying out its functions.

Because the Trusteeship Council suspended its regular operations after completion of the Trusteeship System, this role is now largely historical.

Secretariat and International Organisations

The Secretariat coordinates with:

• specialised agencies;
• UN funds and programmes;
• regional organisations;
• international financial institutions;
• civil society organisations.

The objective is to coordinate international efforts within the broader UN system.

Secretary-General’s Good Offices

One of the most important practical functions of the Secretary-General is the use of good offices.

The Secretary-General may:

• establish communication between parties;
• facilitate negotiations;
• appoint representatives or special envoys;
• encourage peaceful settlement.

This does not normally give the Secretary-General power to impose a binding settlement.

Special Representatives and Envoys

The Secretary-General may appoint:

• Special Representatives;
• Special Envoys;
• Personal Representatives;
• other high-level representatives.

They may be assigned to particular conflicts, regions or political processes.

They act within mandates established by the UN framework.

Appointment of the Secretary-General

The appointment process under Article 97 is:

Security Council recommends candidate

↓

General Assembly appoints Secretary-General

The Charter does not itself specify a fixed term.

In practice, the Secretary-General traditionally serves a five-year term, which may be renewed.

Removal of the Secretary-General

The Charter does not contain a detailed express procedure specifically titled “removal of the Secretary-General.”

In practice, the appointment and renewal process is strongly dependent upon Security Council and General Assembly action.

Because the Security Council recommendation is required, the permanent members have significant practical influence.

Qualifications of Secretariat Staff

Article 101 emphasises:

• efficiency;
• competence;
• integrity.

The Charter also calls for consideration of wide geographical representation.

Thus recruitment seeks to balance:

Merit

Integrity

Competence

Geographical diversity

Privileges and Immunities

UN Secretariat officials enjoy privileges and immunities necessary for the independent performance of their functions.

The principal legal framework includes:

• Convention on the Privileges and Immunities of the United Nations, 1946;
• applicable host-State arrangements;
• relevant international law.

The purpose of immunity is generally functional, not personal privilege for its own sake.

UN Secretariat and Legal Personality

The Secretariat forms part of the United Nations, which possesses international legal personality.

The ICJ recognised the international legal personality of the UN in:

Reparation for Injuries Suffered in the Service of the United Nations (1949)

The Court recognised that the United Nations possesses international legal personality and the capacity necessary to perform its functions.

This provides the broader legal foundation within which the Secretariat operates.

Accountability of Secretariat Officials

International civil servants are subject to:

• UN Staff Regulations;
• Staff Rules;
• administrative procedures;
• internal justice mechanisms;
• applicable codes of conduct.

The international character of their position does not mean that they are beyond institutional accountability.

Neutrality and Independence

The Secretariat must maintain an institutional distinction from national governments.

For example:

State Government

→ Represents national interests

UN Secretariat

→ Serves the interests and purposes of the United Nations

This distinction is essential for the credibility of the organisation.

Secretariat as an International Civil Service

The Secretariat can therefore be understood as an international civil service.

Its personnel are expected to:

• act independently;
• maintain professional integrity;
• avoid political instructions from governments;
• serve the purposes of the UN.

This distinguishes the Secretariat from a traditional national bureaucracy.

Importance of Article 99

Article 99 is particularly significant because it demonstrates that the Secretary-General is not merely an administrative employee.

It gives the office an element of independent political initiative.

The Secretary-General can identify a situation that, in his or her opinion, threatens international peace and security and bring it before the Security Council.

Thus:

Article 97 → Chief administrative officer

Article 98 → Functions and annual report

Article 99 → Independent attention to threats to peace

Article 100 → Independence

Article 101 → Staff

Secretariat and UN Collective Security

The Secretariat supports the wider UN collective-security system.

Security Council

↓

Mandate / Decision

↓

Secretariat

↓

Implementation + Coordination + Reporting

↓

Peacekeeping / Political / Humanitarian Action

The Secretariat therefore provides much of the institutional machinery necessary to translate decisions into practical operations.

Limitations of the Secretariat

The Secretariat does not possess unlimited independent authority.

Dependence on Member States

The organisation depends on Member States for:

• financial contributions;
• personnel;
• political support;
• cooperation.

Charter Limitations

The Secretariat must operate within the powers granted by the Charter and relevant decisions of UN organs.

Political Constraints

The Secretary-General must often work within competing interests of Member States, especially major powers.

Security Council Constraints

On matters involving international peace and security, the Secretary-General cannot simply substitute his or her judgment for the authority of the Security Council.

Administrative Constraints

Large-scale UN operations involve:

• complex bureaucracy;
• financial limitations;
• coordination difficulties.

Important Cases and Authorities

Reparation for Injuries (1949)

Important for the international legal personality of the UN.

Certain Expenses of the United Nations (1962)

Important for understanding:

• powers of UN organs;
• institutional expenditure;
• implied powers.

Namibia Advisory Opinion (1971)

Important for understanding the legal consequences of UN decisions and the role of UN organs.

One-Line Memory Trick

“97–101 = Secretariat”

97 → Secretary-General

98 → Functions + Annual Report

99 → Threat to Peace

100 → Independence

101 → Staff

For the appointment:

Security Council → Recommendation

↓

General Assembly → Appointment

For the institutional role:

Secretariat = Administration + Diplomacy + Coordination + Operations

Conclusion

The UN Secretariat is the administrative and operational backbone of the United Nations. Established under Chapter XV, it performs the continuous work necessary for the functioning of the organisation and its various organs.

The Secretary-General, appointed by the General Assembly upon the recommendation of the Security Council, leads the Secretariat. Although formally described as the chief administrative officer, the Secretary-General has developed an important political and diplomatic role, particularly through good offices, mediation, preventive diplomacy and Article 99.

The independence of the Secretariat is protected by Article 100, while Article 101 establishes the framework for the appointment and service of international civil servants.

For examination purposes, the most important provisions are:

Article 97 → Secretary-General

Article 98 → Functions

Article 99 → Power to bring threats to peace before Security Council

Article 100 → Independence

Article 101 → Staff

Thus, the Secretariat should be understood not merely as an administrative office, but as a permanent international civil service that provides the institutional, diplomatic, legal and operational machinery through which the United Nations carries out its purposes.
