Sovereignty is one of the central concepts for understanding the political and legal organization of modern societies, understood as a nation's supreme decision-making power, having undergone transformations over time. It was initially associated with the absolute authority of a sovereign, and is currently linked to the popular will of the State (external link) governed by the rule of law.
In parallel, the development of International Law, especially in the criminal sphere, brought new challenges by proposing accountability mechanisms that transcend state borders. The creation of international institutions and the consolidation of principles aimed at protecting universal values create tension with the idea of absolute sovereignty, demanding a balance between States and the globe.
In this way, the action of governing nations in the international arena, guided by constitutional principles, reveals the difficulties in protecting their citizens and defending fundamental values. Thus, an analysis of the Marco Archer case allows for a deeper understanding of the limits and possibilities of sovereignty in the face of the demands of contemporary law.
1. State Sovereignty
Sovereignty constitutes one of the fundamental pillars of modern political organization; it refers to the supreme decision-making power within a politically organized society, characterized as the ultimate authority that is subordinate to no other. In this context, it is traditionally attributed to the State, understood as the entity responsible for creating and maintaining legal norms, guaranteeing social order and internal functioning.
Historically, sovereignty has undergone various transformations over time; figures such as Thomas Hobbes advocated for the concentration of sovereign power in the figure of the absolutist monarch, considered indispensable for ensuring order and preventing social chaos. In this sense, the legitimate use of force was a necessary element for maintaining sovereignty, while contrasting ideas associated it with the power to legislate, understanding that the sovereign would be capable of creating laws without being subject to them.
With the changes brought about by modernity and the consolidation of Democracy, the understanding of sovereignty underwent changes; in contemporary States, sovereign power came to be associated with the popular will—that is, with the collective body of citizens who, through representative mechanisms, began to elect their rulers. However, other currents defend the centrality of state institutions, arguing that only the State possesses the instruments to establish and enforce compliance with the rules and laws that organize societies.
Furthermore, sovereignty itself is tied to the definition of the State, characterized by exercising authority over a territory, a population, and a government. In light of this, it represents the ability of a nation to act autonomously both internally and externally, defending its interests before other governing institutions.
In this way, sovereignty is understood as the foundation of legitimate political power, whose nature and titularity vary according to historical context and model of social organization, enabling it to remain dynamic in line with transformations in societal political structures.
2. CRIMINAL JURISDICTION IN INTERNATIONAL LAW
International Criminal Law emerged from the need to address crimes that transcend borders and affect values fundamental to humanity, regardless of their location. It is a legal system aimed at the definition, repression, and prosecution of extremely serious conduct, such as genocide, war crimes, crimes against humanity, and the crime of aggression, the gravity of which demands a response extending beyond the boundaries of States.
Historically, this branch of law was consolidated shortly after the end of World War II, particularly with the Tokyo Trial, which inaugurated individual criminal responsibility within the international arena. Over time, the adoption of the 1998 Rome Statute represented a decisive milestone by establishing the International Criminal Court (ICC), a permanent body designed to prosecute those accused of the most serious crimes against the global community.
Among its foundations are principles that guide its application: the principle of individual criminal responsibility establishes that only natural persons can be held liable, even when acting on behalf of a nation; the principle of complementarity determines that international jurisdiction acts in a subsidiary manner, intervening only when States are unable or unwilling to prosecute the crimes; alongside these, the principle of universality allows any State to exercise jurisdiction over certain crimes, regardless of where they occurred.
Within law, there is a coexistence between national and international jurisdictions, which typically creates tensions related to state sovereignty. Although the ICC plays a central role in global criminal accountability, its operation depends on the cooperation of governing nations, both for investigations and for decisions. This highlights an attempt to strike a balance between preserving state sovereignty and the need to prevent impunity for crimes of high impact.
In practice, International Criminal Law requires mechanisms of legal cooperation between countries, such as mutual assistance, an essential instrument for enabling criminal prosecution in a globalized setting. However, it faces various challenges, such as legislative discrepancies, political issues, human rights concerns, and the need to adapt to new forms of transnational crime, revealing a field in constant transformation. Furthermore, the effectiveness of international decisions is often limited by the absence of its own coercive enforcement mechanisms.
Thus, this branch of law represents a major advance in protecting universal values, seeking to ensure justice on a global scale despite structural and political limitations. Its existence demonstrates the community's effort to build mechanisms capable of holding individuals accountable for crimes that threaten human dignity, reaffirming the commitment to justice and fundamental rights.
3. FOREIGN POLICY PRINCIPLES
Brazilian foreign policy is legally grounded in Article 4 of the Federal Constitution of 1988. However, when analyzing the State's actions in the Archer case, it is essential to observe the legal foundation that guides national diplomacy.
Article 4 establishes fundamental principles, such as the prevalence of human rights (item II) and the peaceful settlement of conflicts (item VII). Thus, as a State that permits the death penalty exclusively in cases of declared war (Art. 5, XLVII), Brazil projects itself internationally. By interceding on behalf of a Brazilian citizen sentenced to death, Brazil acts in defense of individual life and in an attempt to export a humanitarian norm regarded as universal—the Declaration of Human Rights.
However, when analyzing Article 1 (item I) of the Magna Carta, sovereignty is observed as a foundation of the Republic, making it crucial that other sovereignties are respected. Therefore, Brazil recognized Indonesia's legal sovereignty, but found itself in a paradox, feeling compelled to challenge acts that violate the integrity of its citizens' lives.
4. DIPLOMACY AS AN INSTRUMENT OF NATIONAL PROTECTION
In the sphere of Public International Law and International Relations, the protection of individuals abroad is governed primarily by the Vienna Convention on Consular Relations (1963). Article 36 guarantees the State the right to communicate with its detained citizens and to organize their defense. In this way, for a proper analysis of the case, it is crucial to distinguish between the two levels of state action employed—consular assistance and diplomatic protection.
Consular assistance takes the form of legal and administrative support, in which the consulate ensures fundamental guarantees for the detained individual—decent conditions, access to legal counsel, and an interpreter. When analyzing Marco's case, it is evident that the Brazilian State diligently fulfilled its role by providing consular assistance from the time of the Brazilian's arrest in 2003.
Diplomatic protection, on the other hand, occurs when the State takes up the claim of its national, transforming it into an inter-state issue. In the case in question, Brazil resorted to a plea for clemency—requesting a pardon or commutation of the sentence on strictly humanitarian grounds, without questioning the legal merits of the foreign trial.
However, this protection imperative conflicts with Article 4 of the Constitution—which upholds non-intervention (item IV) and equality among States (item V). Thus, a scenario of constitutional contradiction arises, in which the Brazilian State vehemently repudiates the penalty established by the State of Indonesia, yet finds itself constrained, given that its actions must be diplomatic and grounded in peaceful persuasion—rather than coercion.
In this context, Brazilian soft power was brought into play—the ability to influence other States through attraction and persuasion, without resorting to military or financial coercion. The direct involvement of Heads of State—demonstrated in the letters of Luiz Inácio Lula da Silva and the telephone calls from Dilma Rousseff to Indonesian leader Joko Widodo—illustrates the transition from consular bureaucracy—the technical and legal role of consuls—to summit diplomacy—direct and personal political intervention by Heads of State. However, it should be noted that this high-level mobilization also responded to domestic demand, driven by media pressure and public outcry.
5. Analysis of the Marco Archer Case
The case of Marco Archer Cardoso Moreira represents a milestone in the history of Brazilian foreign policy. Arrested in 2003 at the airport in Jakarta—the capital of Indonesia—while attempting to enter the country carrying 13.4 kg of cocaine, Archer was tried and sentenced to capital punishment under local zero-tolerance anti-narcotics legislation. In January 2015, Marco was executed by firing squad after legal and diplomatic remedies were exhausted.
First and foremost, it must be highlighted that analyzing the case requires understanding that Indonesian legislation (Law No. 35/2009) classifies narcotics trafficking as an extraordinary crime. Thus, from an international perspective, Indonesia relied on the principle of territorial jurisdiction—the guarantee that the State possesses full authority to judge and punish any offense committed within its territory.
Furthermore, Itamaraty's argument was grounded on two pillars: the primacy of the absolute right to life and the ineffectiveness of capital punishment in combating global drug trafficking. In contrast, the Indonesian government instrumentalized the case as a symbol of political identity. Thus, the refusal of clemency signaled that the Asian country would not yield to pressure from Western powers—such as Brazil.
On January 17, 2015, Brazil recalled its ambassador to Jakarta for consultations, signaling grave discontent. In addition, the Presidency of the Republic refused to accept the credentials of the new Indonesian ambassador, Toto Riyanto, during a ceremony at the Planalto Palace. Carrying out this act publicly generated pragmatic repercussions. Indonesia threatened to suspend military contracts—such as the purchase of Super Tucano aircraft (Embraer) and Avibras systems, affecting hard power—just as Brazil’s attempt to mobilize international condemnation undermined its coalition-building power in the region, given that the "zero tolerance" policy enjoys significant support within the Association of Southeast Asian Nations (ASEAN).
The political impact of Archer's execution by firing squad was amplified by intense international media coverage and public outcry. However, the case exposed the incoherence of the system, in which many States champion the universality of human rights yet opt for strict deference to state sovereignty when diplomatic confrontation threatens broader economic or political interests. Furthermore, by being able to carry out the sentence without facing international isolation, Indonesia revealed that invocations of sovereignty often serve as a shield against humanitarian violations.
6. Final Considerations
It is concluded that sovereignty has evolved from an absolute power into a democratic model, increasingly relativized by global interdependence and the advancement of International Criminal Law.
Therefore, a continuous reconciliation between State autonomy and global jurisdiction is essential, making state power more flexible in order to combat impunity for grave crimes and ensure order, justice, and human dignity at the transnational level.
Thus, the Marco Archer case is of paramount relevance, as it demonstrates that state sovereignty plays a foundational role in the anarchic international system and that the defense of Human Rights depends not only on moral or legal legitimacy, but also on diplomatic and political pressure. In the face of the limits imposed by the principle of non-intervention, Brazil fully fulfilled its constitutional duty, as consular assistance and diplomatic protection were duly provided. However, International Law offers no coercive mechanisms to prevent an execution legitimized by a sovereign State.
Thus, only by replacing reactive diplomacy—aimed merely at remedying episodic cases—with institutionalized legal instruments—formal, preventive, and binding mechanisms of interstate cooperation, such as bilateral agreements—will it be possible to ensure effective protection for Brazilians abroad.
