The Doctrine of Self-Determination affirms that peoples—not governments—have the right to choose their political status and to pursue their economic, social, and cultural development.

It is a cornerstone of decolonization and is recognized under the UN Charter and the International Covenant on Civil and Political Rights. In international law, self-determination has erga omnes character—meaning it is owed to the international community as a whole, not just to a specific State.

High-yield in Public International Law, often tested alongside state sovereignty, territorial integrity, use of force, and jurisdiction of international courts. A recurring trap is assuming that recognition of an erga omnes right automatically gives courts jurisdiction—it does not.

East Timor

(Portugal v. Australia), ICJ Reports 1995.

Portugal challenged a treaty between Australia and Indonesia allowing joint exploitation of Timor Sea resources, arguing it violated the right of the people of East Timor to self-determination while the territory was under Indonesian occupation.

Although the ICJ affirmed that self-determination is an erga omnes* right, it dismissed the case for lack of jurisdiction, holding that deciding Australia’s responsibility would necessarily require ruling on Indonesia’s legal rights and conduct, even though Indonesia had not consented to the Court’s jurisdiction. Applying the Monetary Gold principle, the Court refused to proceed.

🥜 Even when a right is erga omnes (like self-determination), the ICJ cannot rule if doing so would determine the rights of a non-consenting third State.

*An erga omnes right is a right owed to everyone, not just to one country. It protects fundamental interests of the entire international community, so any state can raise a legal complaint when it is violated—even if that state was not directly harmed.

Think of it this way:
If ordinary international obligations are like private contracts between states, erga omnes rights are public rules—when they’re broken (e.g., genocide, slavery, torture), the whole world has standing to object, not just the victim state.
