UNSC Veto Power

UNSC Veto power has been questioned and debated numerous times. It requires balancing great-power privilege with collective security. Read here to learn more.

At the 81st Session of the United Nations General Assembly (UNGA) in September 2026, French President Emmanuel Macron renewed calls for regulating the use of the UN Security Council (UNSC) veto in situations involving mass atrocities.

France and Mexico’s initiative has now secured the support of 128 UN Member States, including the United Kingdom, making France and the UK the two permanent members supporting this voluntary restraint framework.

The renewed debate highlights a fundamental dilemma of the UN system:

How can the UNSC retain the participation of major powers necessary for collective security while preventing the veto from paralysing international action during grave humanitarian crises?

What is the UNSC Veto power?

The UNSC is the principal UN organ responsible for maintaining international peace and security.

It has 15 members:

• 5 permanent members (P5): China, France, Russia, the United Kingdom and the United States.
• 10 non-permanent members, elected by the UNGA for two-year terms.

The term “veto” does not appear explicitly in the UN Charter. Its legal basis lies principally in Article 27(3), which requires at least nine affirmative votes for substantive Security Council decisions, including the concurring votes of the permanent members.

Thus, any P5 member’s negative vote can prevent adoption of a substantive draft resolution.

Why was the veto created?

The veto was essentially a political compromise embedded in the post-World War II international order.

The founding powers recognised that a collective-security system would be difficult to sustain if it could impose binding decisions against the vital interests of the major military powers.

Hence, the veto simultaneously serves two competing purposes: great-power participation and collective-action constraints

The French-Mexican Initiative

France and Mexico launched their initiative in 2015, building on France’s earlier 2013 commitment to exercise voluntary restraint.

• It calls upon the permanent members to voluntarily refrain from using the veto when genocide, crimes against humanity or large-scale war crimes are being committed.
• Importantly, this is a political commitment rather than a legally binding amendment to the UN Charter.
• At UNGA 81, France and Mexico reported that 128 states supported the initiative, with 21 states joining during the preceding four months.
• President Macron subsequently called for securing the commitment of all five permanent members.

The initiative attempts to transform the debate from “Can the veto legally be abolished?” to “Can permanent members voluntarily exercise the existing veto more responsibly?”

This distinction is important because Charter amendment is considerably more difficult than voluntary political restraint.

Why has Veto Reform Become Important?

1. Security Council paralysis

The UNSC has repeatedly struggled to reach consensus on major conflicts where permanent members have divergent geopolitical interests.

The resulting paralysis can affect:

• Ceasefire resolutions
• Sanctions
• Peacekeeping mandates
• Humanitarian access
• Arms embargoes
• Collective responses to mass atrocities

Consequently, the credibility of the Council depends not only on its legal authority but also on its ability to act when international peace and civilian protection are at stake.

2. Representation versus historical power

The P5 structure reflects the geopolitical configuration of 1945.

The contemporary international system, however, includes:

• Emerging powers
• Major economies outside the P5
• Greater representation of Africa, Asia and Latin America
• New security challenges such as cyberwarfare, climate-related instability and emerging technologies

Countries such as India, Brazil, Germany and Japan, collectively associated with the G4, have sought permanent representation.

France itself has supported expansion of the Council and has reiterated support for India’s permanent membership.

Complementary Mechanism: The Liechtenstein Initiative

In 2022, the UNGA adopted Resolution 76/262, establishing a standing mandate for the General Assembly to debate a situation whenever a veto is cast in the Security Council.

• The Assembly is to convene within 10 working days of the veto, subject to the conditions specified in the resolution.
• It does not eliminate or override the veto.
• Instead, it creates a veto, then General Assembly debate and public scrutiny
• This increases the political and diplomatic cost of using the veto.
• For example, the mechanism has already been invoked following vetoes concerning conflicts including Gaza and Sudan.

The ACT Code of Conduct

The Accountability, Coherence and Transparency (ACT) Group has promoted a Code of Conduct calling upon Security Council members to refrain from voting against credible Council action intended to prevent or halt mass atrocity crimes.

It represents another form of normative restraint, rather than a formal Charter amendment.

Together, the French-Mexican initiative, ACT Code and Resolution 76/262 represent three different approaches:

Mechanism	Core Approach
French-Mexican Initiative	Voluntary restraint on veto in mass atrocities
ACT Code of Conduct	Responsible voting against atrocity-prevention action
Liechtenstein Initiative	Mandatory General Assembly debate after a veto

Arguments for Regulating the Veto

1. Preventing humanitarian paralysis

• When large-scale civilian suffering occurs, inability to reach a Security Council decision can weaken the UN’s capacity to fulfil its central peace-and-security mandate.
• Voluntary veto restraint could preserve Council action in the most extreme situations.

2. Strengthening legitimacy

• The UN is founded on the principle of the sovereign equality of its members under Article 2(1).
• Although the veto is constitutionally embedded in the Charter, its unrestricted political use can generate perceptions of unequal treatment among Member States.
• Greater restraint could therefore strengthen the Council’s legitimacy.

3. Reconciling power with responsibility

• Permanent membership provides extraordinary institutional influence.
• A corresponding expectation of responsible exercise of that influence can strengthen the normative legitimacy of the Council.
• The French-Mexican proposal therefore does not necessarily challenge permanent membership itself; it challenges the unrestricted use of the veto in defined atrocity situations.

4. Increasing accountability

• Resolution 76/262 demonstrates that even where the veto cannot be prevented, its use need not end international deliberation.
• A veto can instead trigger UNSC deadlock, UNGA scrutiny, diplomatic pressure, humanitarian and political follow-up.

Arguments Against Abolishing the Veto

1. Great-power consensus remains central to collective security

• The veto reflects the political reality that the UN cannot easily enforce decisions against the fundamental interests of the world’s major military powers.
• Removing the veto without securing their continued participation could potentially weaken the effectiveness of the collective-security system.

2. Charter amendment is extremely difficult

Under Article 108, a Charter amendment requires:

1. Adoption by a two-thirds majority of the UNGA
2. Ratification by two-thirds of UN Member States
3. Ratification by all five permanent members

Therefore, abolition or fundamental restructuring of the veto requires the consent of the very states whose veto powers would be affected.

This creates a structural obstacle to formal abolition.

3. Defining an “atrocity” can itself be politically contested

• Genocide
• Crimes against humanity
• War crimes
• Mass atrocities

Such terms have legal meanings, but their application to unfolding conflicts can become politically contentious.

A poorly designed trigger mechanism could therefore produce disputes.

4. Veto multiplication

• Simply expanding permanent membership while extending veto privileges to every new permanent member could increase the number of actors capable of blocking Council action.
• Therefore, council enlargement and veto reform should be treated as related but distinct questions.

Abolition vs Regulation

The debate is often framed as “retain or abolish the veto.” However, reform can occur at several levels:

• Legal abolition: Requires Charter amendment and therefore P5 ratification.
• Limitation of scope: The veto could theoretically be restricted to certain categories of decisions, but this would require agreement on the relevant Charter framework.
• Voluntary restraint: P5 members can politically commit not to use the veto in defined circumstances.
• Post-veto accountability: The international community cannot prevent the veto but can ensure that it automatically generates public scrutiny and diplomatic consequences.

The French-Mexican initiative and Liechtenstein mechanism primarily operate at Levels 3 and 4, making them more immediately feasible than formal abolition.

India’s Perspective

For India, the veto debate must be viewed alongside the broader issue of UNSC reform.

India has consistently sought permanent membership of an expanded Security Council, arguing that contemporary global realities are inadequately reflected in the present composition.

France has explicitly reiterated support for India’s permanent membership.

India therefore has an interest in a reform process that simultaneously addresses:

• Equitable geographical representation
• Greater representation of developing countries
• African representation
• Permanent membership
• Veto arrangements
• Effectiveness of Council decision-making

A key challenge is designing an expansion model that improves representativeness without producing additional institutional paralysis.

Way Forward

1. Build consensus around voluntary veto restraint

• The French-Mexican initiative provides a relatively pragmatic starting point because it does not immediately require Charter amendment.
• The immediate objective should be to expand political support and encourage all P5 members to adopt comparable commitments.

2. Strengthen objective atrocity-determination mechanisms

Veto restraint would be more credible if based on transparent factual thresholds.

Potential inputs could include:

• UN fact-finding missions
• OHCHR reporting
• UN investigative mechanisms
• International judicial findings
• Credible independent evidence

However, the final mechanism should preserve due process and avoid politicisation.

3. Give greater practical significance to UNGA Resolution 76/262

Post-veto debates should not become merely symbolic.

They could be linked to:

• Humanitarian coordination
• Fact-finding
• Mediation
• Peacebuilding
• Accountability mechanisms
• Appropriate action under existing UNGA procedures

4. Strengthen the “Uniting for Peace” option

• Where Security Council paralysis persists, the General Assembly can consider the framework established by Resolution 377A (V), popularly known as “Uniting for Peace.”
• It does not substitute the Security Council but provides a mechanism for broader collective consideration when the Council is unable to act.

5. Reform representation alongside veto reform

• A sustainable UNSC reform package should address both: Who sits at the table? and how are decisions made?
• Greater representation of Africa, Asia and Latin America is essential for the Council’s contemporary legitimacy.

6. Preserve the distinction between responsibility and effectiveness

• Veto reform should not simply make it easier to pass resolutions.
• The ultimate objective should be a Council capable of producing credible, implementable and legitimate collective action.

Conclusion

The UNSC veto is simultaneously a constitutional feature of the UN system, a mechanism of great-power accommodation and a source of institutional paralysis.

Its complete abolition remains difficult because of the amendment requirements under Article 108. However, the current debate demonstrates that reform need not begin with abolition.

The French-Mexican initiative, now supported by 128 states, and the Liechtenstein mechanism represent two complementary approaches: voluntary restraint before the veto and institutional accountability after it.

The long-term objective should be to evolve the Security Council from a structure primarily reflecting the power distribution of 1945 into one that combines representativeness, effectiveness and accountability.

The question is therefore not merely whether the veto should exist, but how the exceptional power attached to it can be exercised consistently with the UN’s purpose of maintaining international peace and security.
