Meaning of Sovereignty
Sovereignty is the supreme, absolute and uncontrollable power of a state to make and enforce laws within its territory without any external interference.
The concept of sovereignty was popularized by the French political philosopher Jean Bodin in 1576. He argued that for a state to exist, there must be a supreme authority that holds final decision-making power over the citizens. In political science, sovereignty represents the ultimate legal authority of a state to govern itself, maintain public order, and defend its territorial integrity.
A sovereign state is an independent political entity that possesses a defined territory, a permanent population, a government, and the supreme authority to govern its internal and external affairs without foreign control.
Nigeria became a sovereign state on October 1, 1960, when it gained independence from British colonial rule. Before this date, Nigeria was not sovereign because the British colonial administration held the ultimate power to make laws and decisions for the territory. Today, Nigeria has its own constitution, government, and military, which allows it to exercise sovereignty within its borders.
Characteristics of Sovereignty
According to classical political theory, sovereignty possesses several distinct features that distinguish a sovereign state from other political organizations. The main characteristics of sovereignty include:
- Permanence: Sovereignty is a permanent feature of a state. It lasts as long as the state itself exists. While governments, presidents, or political parties may change through elections or other political processes, the sovereignty of the state remains uninterrupted.
- Absoluteness: The power of a sovereign state is unlimited and supreme. There is no higher authority within the state that can override the decisions of the sovereign power. Legally, the state has the power to make any law and enforce it.
- Indivisibility: Sovereignty cannot be divided. The supreme power of a state belongs to the state as a single unit. It cannot be shared between two supreme authorities within the same territory, as this would lead to conflict and political instability.
- Comprehensiveness: The power of the sovereign state extends over all persons, groups, and associations within its territorial boundaries. No individual or organization is above the laws of a sovereign state, and the state’s authority applies to everyone within its borders.
- Exclusiveness: A sovereign state has exclusive control over its territory. No other country or external power has the right to make laws, enforce rules, or exercise authority within that state’s borders without its consent.
- Independence: Sovereignty implies that the state is free from external control. The government can make foreign policy decisions, sign treaties, and interact with other nations on an equal basis.
Limitations of Sovereignty
Although sovereignty is theoretically absolute and unlimited, in practice, no state enjoys absolute sovereignty. Various internal and external factors limit the exercise of supreme power by a state.
Internal Limitations of Sovereignty
Internal limitations refer to the domestic factors within a country that restrict the absolute power of the government. The primary internal limitations are:
- The Constitution: In most modern states, the constitution is the supreme law of the land. The government must act within the limits set by the constitution. Any government action or law that violates the constitution can be declared null and void by the judiciary.
- Public Opinion: Governments must respect the views, wishes, and demands of their citizens. If a government ignores public opinion, it may face protests, strikes, civil unrest, or defeat in the next election.
- The Electorate: In a democratic state, the ultimate power lies with the voters. Citizens can vote a government out of office during periodic elections, which acts as a major check on the exercise of sovereign power.
- Customs, Traditions, and Culture: The sovereign power cannot easily make laws that violate the deeply rooted customs, religious beliefs, or cultural traditions of the people without causing resistance or rebellion.
- Pressure Groups: Civil society organizations, trade unions (such as the Nigeria Labour Congress), and professional bodies can influence government policies and prevent the state from taking arbitrary actions.
External Limitations of Sovereignty
External limitations refer to international factors and relationships that restrict a state’s freedom of action. The primary external limitations are:
- International Law: Sovereign states are expected to respect international laws, rules, and conventions. Violating these laws can lead to international condemnation, economic sanctions, or legal action at the International Court of Justice.
- Membership in International Organizations: When a state joins organizations like the United Nations (UN), the African Union (AU), or the Economic Community of West African States (ECOWAS), it agrees to abide by their treaties, charters, and decisions. This limits its freedom to act entirely as it pleases.
- International Treaties and Agreements: Bilateral or multilateral treaties signed with other nations bind the sovereign state to specific obligations, thereby restricting its absolute power in those areas.
- Foreign Aid and Economic Dependency: Developing nations that rely heavily on foreign loans, grants, or economic aid from bodies like the International Monetary Fund (IMF) or the World Bank often have to accept economic policies dictated by these external institutions.
- Military Alliances: Membership in military pacts or alliances means a state must coordinate its defense policies with other member nations, which limits its independent military decision-making.
- Globalization and Interdependence: In the modern world, countries depend on each other for trade, technology, and security. No state can exist in complete isolation, and this mutual dependence naturally limits absolute sovereignty.
