Abstract
The concept of “peoples” is central to the right of self-determination in international law, yet it lacks a fixed legal definition. This article examines the doctrinal development of the term, the criteria used to identify a “people,” and its interpretation in the jurisprudence of the International Court of Justice (ICJ). It argues that the concept is intentionally flexible, combining objective and subjective elements, and that its application depends on contextual legal analysis rather than rigid classification.

1. Introduction
The right of self-determination is addressed to “peoples,” yet international law provides no definitive definition of this term. This absence creates a central challenge: the scope of the right depends on identifying its beneficiaries.¹
The ambiguity is not accidental. It reflects both the diversity of historical contexts and the political sensitivity of recognizing collective entities with potential claims to autonomy or independence.²
This article seeks to clarify how international law approaches the concept of “peoples,” drawing on doctrinal analysis and ICJ jurisprudence. It aims to identify the criteria used in practice and to assess their legal significance.
2. The Absence of a Fixed Definition
International legal instruments, including the Charter of the United Nations and the human rights covenants, refer to “peoples” without defining the term.³
This omission allows flexibility in application but introduces uncertainty. Unlike the concept of “state,” which is supported by relatively established criteria, “peoples” remains an open-ended category.⁴
Doctrinal analysis suggests that this flexibility is deliberate. A rigid definition could either exclude legitimate claims or encourage fragmentation.⁵ Instead, international law adopts a contextual approach, allowing the concept to evolve in response to specific situations.
3. Objective Criteria
Scholars have identified several objective elements that may indicate the existence of a “people.” These include shared history, cultural traditions, language, and territorial connection.⁶
Such factors provide a basis for identifying collective identity. In many cases, they correspond to historical communities that have developed over time.
However, these criteria are not determinative. Not all groups sharing these characteristics are recognized as “peoples” in a legal sense. Their relevance depends on how they interact with broader legal and political considerations.
4. Subjective Elements and Political Consciousness
In addition to objective criteria, the concept of “peoples” includes subjective elements, particularly the existence of a shared sense of identity and political will.⁷
This dimension reflects the idea that a “people” is not merely a collection of individuals with common traits, but a community that perceives itself as such.
The role of political consciousness is especially important in the context of self-determination, as it relates to the expression of collective will. Without such a dimension, the concept would be reduced to purely descriptive characteristics.
5. ICJ Jurisprudence
The jurisprudence of the International Court of Justice provides important insights into the interpretation of “peoples.”
In the Western Sahara Advisory Opinion (1975), the Court emphasized the principle of self-determination through the free and genuine expression of the will of the people.⁸ Although it did not define “peoples,” the decision highlighted the centrality of collective will in determining status.
In the Namibia Advisory Opinion (1971), the Court addressed the illegality of South Africa’s continued presence and reinforced the role of self-determination in decolonization.⁹
The East Timor case (1995) further recognized self-determination as an obligation erga omnes, implicitly affirming the importance of identifying the relevant “people.”¹⁰
These decisions demonstrate that the Court approaches the concept pragmatically, focusing on context rather than formal definition.
6. Colonial and Post-Colonial Contexts
The identification of “peoples” has been most clearly articulated in the context of decolonization. In such cases, colonial populations were generally treated as distinct “peoples” entitled to self-determination.¹¹
Outside this context, the situation becomes more complex. Claims by sub-state groups, minorities, or regional populations raise difficult questions about the limits of the concept.
International law has been cautious in extending the definition, reflecting concerns about stability and the potential for fragmentation.
7. Doctrinal Debates
Scholarly debate on the concept of “peoples” reflects the tension between inclusivity and restraint. Some approaches emphasize objective criteria, while others prioritize subjective identity and political will.¹²
A more balanced view recognizes that both dimensions are necessary. A purely objective approach risks ignoring the agency of communities, while a purely subjective approach may lack legal coherence.
The absence of a definitive rule has led to a case-by-case approach, in which legal, historical, and political factors are considered together.
8. Legal Implications
The identification of a “people” is a prerequisite for invoking the right of self-determination. As such, it has significant legal implications.
Where a group is recognized as a “people,” it may claim rights relating to political participation, autonomy, or, in certain circumstances, external self-determination.¹³
However, recognition does not automatically lead to independence or secession. The exercise of self-determination remains subject to other principles, including territorial integrity and international stability.
9. Conclusion
The concept of “peoples” in international law is inherently flexible and context-dependent. It combines objective and subjective elements, reflecting both historical identity and collective will.
The jurisprudence of the ICJ confirms that there is no rigid definition. Instead, the identification of a “people” depends on a careful assessment of legal and factual circumstances.
This flexibility allows international law to adapt to diverse situations, but it also requires rigorous analysis to ensure consistent and principled application.
