Sovereignty, expulsion, and the precarious tenure of temporary protection
In Brief
- The power to expel aliens is an inherent, fundamental, and confirmed instrument of state sovereignty, described by some legal authorities as a 'weapon of defense and reprisal'.
- Temporary residency or protection is a revocable privilege, not a 'vested right' equivalent to citizenship, leaving aliens in a state of precarious tenure defined by the will of the host state.
- Nationality is the crucial link for international protection; lacking it (statelessness) results in profound vulnerability and lack of diplomatic redress.
- The state's absolute power to expel is continually contested by international human rights frameworks, which ground protection in universal human personality rather than national affiliation.
The power to define who belongs and who may be expelled is a fundamental attribute of the modern nation-state [1]. International law recognizes this authority, confirming that every sovereign state possesses the inherent competence to expel an alien from its territory at any moment, regardless of whether their presence is temporary or they have established a domicile [2]. This right of expulsion is not a dormant power but a critical tool of national policy, often invoked in response to perceived threats or as a matter of public good [3]. It represents the ultimate expression of territorial and personal supremacy, where the state reasserts its control over its borders and population.
This sovereign prerogative, however, does not exist in a vacuum. It operates in a persistent and often sharp tension with a body of international customs and conventions that extend protections to individuals based on principles of human dignity rather than citizenship alone [4]. While aliens are physically within a state's jurisdiction, they may also remain under the protection of their home state, creating a complex web of overlapping authorities and obligations [5]. The host state, in turn, is generally compelled by international norms to grant foreigners a certain standard of treatment, particularly equality before the law regarding the safety of their person and property [6].
This creates a precarious threshold for the non-citizen. Their status is marked by an inherent ambiguity, where a grant of temporary residence or protection can be revoked, transforming them from a protected person into an alien subject to removal. Individuals in this position may contend that their long-term, lawful residence confers a 'vested right' to remain, equivalent to that of a citizen [7]. Yet, the state's power to expel challenges this very notion, creating a recurring conflict between the security and interests of the collective and the rights and humanitarian needs of the individual. At what point does protection cease and the state's right to expel become absolute? This question lies at the heart of the legal and ethical dilemmas surrounding temporary protection and the ever-present possibility of deportation.
Sovereignty's Sharpest Edge: The Unquestioned Power to Expel
The authority to deport is one of the most direct manifestations of state sovereignty, described as a 'weapon of defense and reprisal confirmed by international law' . This power is not contingent on a state of war or extreme emergency; it can be exercised based on congressional or governmental apprehension of dangers, whether foreign or internal . States view the ability to exclude foreigners as an essential component of self-protection [8]. This competence is derived from the principle of territorial supremacy, which holds that a state has the authority to regulate all persons and activities within its borders [9]. Consequently, a state is under no international obligation to admit a fugitive, and if it does, it retains the right to expel them later, absent specific treaty stipulations to the contrary .
This inherent power is codified and operationalized through national legislation, which provides the legal framework for removal. For instance, laws may stipulate that a non-citizen is liable to deportation for violating the conditions of their stay, remaining beyond their permitted time, or if a government official, such as a Secretary of State, deems their expulsion 'conducive to the public good' . The legal mechanisms for enforcing this power are robust; they include giving directions to transport captains for the physical removal of an individual to their country of origin or another territory that will accept them [10]. Furthermore, legal challenges to these decisions are often curtailed, with appeals being dismissed if an individual is classified as an illegal entrant or already has a deportation order in force [11].
The exercise of deportation power is frequently political, targeting individuals for 'conduct displeasing to the lawmakers' [12]. It can be used as a tool to deal with perceived ideological threats, as seen in historical cases where the goal was to secure evidence against suspected anarchists for deportation proceedings in the event they were not convicted of other crimes [13]. This underscores that the criteria for expulsion are not merely administrative but can be deeply intertwined with national security, political ideology, and the maintenance of public order. The very claim of citizenship acts as a fundamental barrier to this entire process, as it challenges the state's 'essential jurisdictional fact' and requires a judicial determination of status before executive action can proceed [14]. This starkly illustrates the legal chasm between the citizen, who is secure from expulsion, and the alien, who is not.
The Anchor of Nationality: Between Belonging and Statelessness
Nationality serves as the primary 'link between this law and individuals' in the international system [15]. It is through this legal bond that a person can claim the benefits of international law, most notably the right of diplomatic protection from their home state while abroad . This right of protection is a recognized consequence of a state's personal supremacy over its citizens, no matter where they are located [16]. The relationship is reciprocal: the citizen owes allegiance, and in return, the government owes protection [17]. This framework establishes a clear hierarchy where rights and protections are fundamentally tied to national belonging.
The absence of nationality, therefore, creates a profound vulnerability. A stateless person lacks a home state competent to advocate on their behalf if they are aggrieved by another country . They exist in a legal void, enjoying no guaranteed protection under the traditional state-centric model of international law. This problem becomes particularly acute when a stateless individual is expelled, as their home state has a duty to receive its own expelled nationals, but no such duty exists for those who lack a nationality [18]. Such cases are considered a 'blemish' on both municipal and international law, revealing a critical gap in the global system of protection .
Challenging this state-centric paradigm is the modern human rights framework, which posits that fundamental rights are not derived from one's status as a national but are based on the inherent attributes of 'human personality' . This perspective justifies a system of international protection that complements and sometimes overrides the domestic laws of states. From this viewpoint, the right to a nationality itself is a fundamental human right, and no one should be arbitrarily deprived of it [19]. This creates a direct ideological conflict with the notion of absolute state sovereignty over matters of entry and expulsion. While one system anchors rights in the political community of the nation-state, the other grounds them in a shared humanity that transcends borders, providing the moral and legal basis for concepts like asylum and non-refoulement, even when they conflict with a state's immediate interests.
Temporary Protection and the Ambiguity of Rights
The status of an alien granted temporary protection is defined by its inherent impermanence. Their domicile is held by a 'precarious tenure' , and their continued presence is conditional upon the will of the host state. Even aliens admitted for permanent residence cannot assume their status is a 'vested right' equal to that of a citizen; they remain subject to the state's power to expel . This is reinforced by the legal principle that an alien who voluntarily leaves the country, even for a temporary period, may be subject to prevailing immigration laws upon their return, effectively treating them as a new entrant [20]. This legal fragility underscores that temporary protection is a revocable privilege, not an immutable right.
The rights afforded to non-citizens within a host country are a subject of significant legal and political tension. While international custom compels states to provide aliens with equality before the law concerning personal and property safety , and domestic frameworks may speak of protecting the rights of all 'persons' in a territory [21], this protection is often qualified. A competing and powerful political perspective holds that a government's 'first duty' is to its own people and that an alien has no 'legal rights whatever' under the constitution of the host country [22]. This view subordinates the interests of non-citizens to those of the national population, particularly in matters of immigration.
This dynamic of provisionality extends to concepts like asylum. The so-called right of asylum is not a right held by the individual to demand entry and protection; rather, it is the 'competence' of a state to grant shelter if it chooses [23]. The decision to provide refuge is a discretionary act of territorial supremacy. Similarly, any temporary arrangement, whether for humanitarian reasons or political expediency, is subject to re-evaluation by the state [24, 25]. The state ultimately retains the power to determine when such temporary conditions have ceased, and its right to regulate its population can be reasserted. This leaves individuals under temporary protection in a state of perpetual uncertainty, where their ability to remain is contingent on a complex interplay of domestic law, international norms, and the shifting political priorities of the host nation.
The power to expel non-citizens remains a potent and legally confirmed instrument of state sovereignty . It is embedded in national legal systems and justified by the foundational principle of self-protection . This authority creates a clear and consequential distinction between the citizen, secure in their right to remain, and the alien, whose presence is conditional and whose claim to a 'vested right' of residence is ultimately subordinate to the state's will . The legal status of the alien is thus one of inherent precariousness, defined by the constant possibility that temporary protection may be withdrawn.
However, this sovereign power is contested by a parallel framework of international human rights that grounds protection in universal human dignity rather than national affiliation . The 'threshold of alienage' is therefore not a static legal line but a dynamic and contested frontier. It is where the state's assertion of control confronts the principle that all persons are entitled to certain fundamental protections. The fate of the individual who crosses this threshold—whether through the expiration of a visa, a change in policy, or a shift in the political climate—is determined by the enduring tension between the state's right to define its community and the universalist ideal of rights that know no borders.
