Advancing Global Human Rights: The Impact of the Second Optional Protocol on Abolishing the Death Penalty

Introduction

The global discourse on human rights has long grappled with the contentious issue of the death penalty, a practice that stands in stark contrast to the principles of human dignity and the right to life enshrined in international law. The Second Optional Protocol to the International Covenant on Civil and Political Rights, Aiming at the Abolition of the Death Penalty (hereinafter referred to as the Second Optional Protocol), adopted by the United Nations General Assembly on December 15, 1989, represents a landmark instrument in the pursuit of global abolition of capital punishment. Entering into force on July 11, 1991, this treaty commits its state parties to abolish the death penalty within their jurisdictions, marking a significant step forward in the progressive development of human rights.

This article examines the impact of the Second Optional Protocol on advancing global human rights, with a particular focus on its legal mechanisms, the process of treaty entry, and its implications for national legal systems. Given the instruction to analyze treaty entry and implementation in the context of a specific country, this article will assume a generic or hypothetical country for illustrative purposes (referred to as “State X”) since no specific country was named. The discussion will explore how State X can legally enter into treaties such as the Second Optional Protocol, whether it adopts a monist or dualist approach to the incorporation of international law into national law, and the broader implications of the treaty’s relationship with the Vienna Convention on the Law of Treaties (VCLT) of 1969. Additionally, the article will assess how the Second Optional Protocol influences other countries in their treaty-making processes and contributes to the global human rights framework.

The Second Optional Protocol: A Framework for Abolition

The Second Optional Protocol is a subsidiary agreement to the International Covenant on Civil and Political Rights (ICCPR), adopted in 1966, which itself recognizes the right to life under Article 6 while allowing for limited use of the death penalty in countries that have not abolished it. The Protocol, however, goes further by binding state parties to a complete prohibition of executions within their jurisdictions. As articulated in its preamble, the Protocol is grounded in the belief that “abolition of the death penalty contributes to enhancement of human dignity and progressive development of human rights” (United Nations, 1989).

Key provisions of the Second Optional Protocol delineate the obligations of state parties. Article 1(1) states, “No one within the jurisdiction of a State Party to the present Protocol shall be executed,” while Article 1(2) requires states to “take all necessary measures to abolish the death penalty within its jurisdiction” (United Nations, 1989). Article 2(1) allows for a reservation at the time of ratification or accession, permitting the application of the death penalty in time of war for the most serious military crimes, though such reservations must be explicitly declared (United Nations, 1989). As of recent data available on the web, 92 state parties have ratified the Protocol, with the most recent being Zambia on December 19, 2024, reflecting a growing global commitment to abolition (Wikipedia, 2024).

The Protocol does not merely serve as a symbolic gesture; it imposes binding obligations under international law, monitored by the Human Rights Committee, which oversees compliance with the ICCPR and its protocols. States parties are required to submit periodic reports detailing measures taken to implement the Protocol, ensuring accountability and fostering dialogue on human rights practices (OHCHR, n.d.).

Legal Entry into Treaties: The Case of State X

The process by which a country enters into international treaties, such as the Second Optional Protocol, is governed by both international and domestic legal frameworks. Internationally, the Vienna Convention on the Law of Treaties (VCLT) of 1969 provides the foundational rules for treaty-making, including signature, ratification, accession, and reservation processes. Domestically, the constitution or legal system of a state dictates the procedural requirements for treaty entry. Since the specific country under analysis is not defined, this section will hypothesize the legal framework of State X to illustrate how it might engage with the Second Optional Protocol.

Under international law, as outlined in Article 11 of the VCLT, states may express consent to be bound by a treaty through signature, ratification, acceptance, approval, or accession (United Nations, 1969). The Second Optional Protocol specifies its entry into force under Article 8(1), which states that it “shall enter into force three months after the date of the deposit of the tenth instrument of ratification or accession” (United Nations, 1989). For State X to become a party, it must follow this process, typically involving the deposit of an instrument of ratification or accession with the United Nations Secretary-General, as per Article 8(2) of the Protocol (United Nations, 1989).

Assuming State X operates under a typical constitutional framework, its ability to enter into treaties would be governed by domestic legal provisions. In many countries, the executive branch (e.g., president or government) negotiates and signs treaties, but ratification often requires legislative approval to ensure democratic oversight. For instance, if State X’s constitution mirrors that of many parliamentary systems, treaty ratification might require a majority vote in the national legislature before the executive can deposit the instrument of ratification. This process ensures that international commitments align with domestic political will and legal norms.

Additionally, Article 2(1) of the Second Optional Protocol allows State X to make a reservation concerning the application of the death penalty during wartime for serious military crimes, provided such a reservation is made at the time of ratification or accession (United Nations, 1989). This provision offers flexibility for states with specific security concerns to join the Protocol while addressing domestic or political constraints. State X, therefore, would need to assess whether such a reservation is necessary based on its national context and military policies.

Monist vs. Dualist Approaches: Treaty Implementation in State X

The integration of international treaties into national law varies depending on whether a state adopts a monist or dualist approach to international law. A monist system views international and domestic law as part of a single legal order, meaning treaties can become directly applicable in national courts upon ratification, provided they are self-executing or do not require further legislation. In contrast, a dualist system treats international and domestic law as separate spheres, requiring specific domestic legislation to incorporate treaty obligations into national law (Cassese, 2005).

For the purposes of this analysis, let us assume State X operates under a dualist system, which is common in many common law jurisdictions. In such a system, even after ratifying the Second Optional Protocol, State X would need to enact domestic legislation to abolish the death penalty and align its legal framework with the Protocol’s obligations under Article 1(2) (United Nations, 1989). This might involve amending or repealing existing criminal codes that permit capital punishment, as well as establishing mechanisms to ensure no executions occur within its jurisdiction. Failure to pass such legislation could result in a discrepancy between State X’s international obligations and its domestic legal practice, potentially leading to violations of the Protocol and scrutiny by the Human Rights Committee.

If State X were a monist state, ratification of the Second Optional Protocol might immediately render its provisions enforceable in domestic courts, assuming the treaty’s text is clear and specific enough to be self-executing. However, even in monist systems, supplementary legislation might be required for practical implementation, such as defining procedural safeguards or penalties for non-compliance. Regardless of the system, the translation of the Second Optional Protocol into national law underscores the importance of political commitment and institutional capacity to effect legal and cultural change (Shaw, 2017).

In State X’s case, whether monist or dualist, public awareness and judicial training would be critical to ensuring that the abolition of the death penalty is not merely a legal formality but a lived reality. For instance, if State X retains public or political support for capital punishment, there may be resistance to implementing the Protocol’s obligations, highlighting the intersection of law and societal norms in human rights advancement.

Relationship with the Vienna Convention on the Law of Treaties (VCLT) 1969

The Vienna Convention on the Law of Treaties (VCLT), adopted in 1969, is the authoritative framework governing the formation, interpretation, and termination of treaties under international law. While the Second Optional Protocol is not a party to the VCLT—since treaties themselves are not parties, but rather states are parties to the VCLT—its creation, entry into force, and implementation are guided by the principles and rules set forth in the VCLT (United Nations, 1969).

The VCLT applies to treaties concluded after its entry into force on January 27, 1980, as well as to earlier treaties in aspects reflecting customary international law. Since the Second Optional Protocol was adopted in 1989, it falls within the temporal scope of the VCLT for states that are parties to the Convention. Key provisions of the VCLT relevant to the Second Optional Protocol include Article 11 (means of expressing consent to be bound), Article 19 (formulation of reservations), and Article 24 (entry into force of treaties) (United Nations, 1969). These provisions inform how State X and other countries can properly enter into the Protocol, ensuring that their consent is expressed through recognized legal channels, such as ratification or accession, as stipulated in Article 8 of the Protocol (United Nations, 1989).

For states that are not parties to the VCLT, many of its rules are considered customary international law and thus apply universally. This ensures that the process of entering into the Second Optional Protocol remains consistent across different legal systems. For example, the VCLT’s Article 19 allows states to formulate reservations unless prohibited by the treaty itself, which aligns with Article 2(1) of the Second Optional Protocol permitting reservations for wartime executions (United Nations, 1969; United Nations, 1989). This interplay provides a structured approach for countries to engage with the Protocol while accommodating specific national concerns.

The relevance of the VCLT to other countries lies in its universal applicability as a guide for treaty-making. By adhering to VCLT principles, states can ensure that their entry into the Second Optional Protocol is legally sound and internationally recognized. This includes ensuring that ratification or accession is conducted by competent authorities, as per Article 7 of the VCLT, and that any reservations or declarations are communicated clearly to the depositary, in this case, the UN Secretary-General (United Nations, 1969). The VCLT thus serves as a procedural blueprint, fostering consistency and predictability in how states commit to human rights treaties like the Second Optional Protocol.

Impact on Global Human Rights

The Second Optional Protocol has had a profound impact on advancing global human rights by institutionalizing the abolition of the death penalty as a cornerstone of the right to life. With 92 state parties as of December 2024, the Protocol has contributed to a marked decline in the use of capital punishment worldwide, though significant challenges remain in retentionist states (Wikipedia, 2024). Its influence can be observed in several key areas: norm-setting, legal reforms, and international advocacy.

First, the Protocol serves as a normative standard, reinforcing the idea that the death penalty is incompatible with human dignity. By referencing Article 3 of the Universal Declaration of Human Rights and Article 6 of the ICCPR in its preamble, the Protocol situates itself within the broader human rights framework, amplifying the moral imperative for abolition (United Nations, 1989). This normative pressure has encouraged states, even those not party to the Protocol, to reconsider their policies on capital punishment, as evidenced by increasing votes in favor of UN General Assembly resolutions calling for a moratorium on executions (OHCHR, 2014).

Second, the Protocol has catalyzed domestic legal reforms in state parties. Upon ratification, countries are compelled under Article 1(2) to take “all necessary measures” to abolish the death penalty, often necessitating amendments to criminal codes and judicial practices (United Nations, 1989). For instance, states like Armenia, which ratified the Protocol in 2021, have subsequently undertaken legislative steps to eliminate capital punishment from their legal systems (Parliamentarians for Global Action, 2023). These reforms not only align national laws with international obligations but also strengthen the rule of law by prioritizing life over retribution.

Third, the Protocol has bolstered international advocacy for abolition. Organizations like the World Coalition Against the Death Penalty (WCADP) and the Office of the High Commissioner for Human Rights (OHCHR) leverage the Protocol as a benchmark to engage with retentionist states, urging ratification and compliance (WCADP, 2008). The Human Rights Committee, in its periodic reviews, further amplifies the Protocol’s impact by holding state parties accountable for their commitments, creating a feedback loop of scrutiny and progress (OHCHR, n.d.).

Despite these advancements, the Protocol’s impact is limited by its optional nature and the persistence of capital punishment in major powers and regions with cultural or political resistance to abolition. Countries such as the United States, China, and several Middle Eastern states remain outside the Protocol’s ambit, executing significant numbers of individuals annually. This underscores the need for continued diplomatic efforts and grassroots movements to expand the Protocol’s reach and address underlying systemic issues, such as poverty and lack of judicial fairness, that perpetuate the death penalty (Amnesty International, 2020).

Implications for Treaty Entry Processes Globally

The Second Optional Protocol, through its alignment with VCLT principles, offers valuable lessons for how states can approach treaty-making in the human rights domain. First, it highlights the importance of clarity in treaty obligations and entry mechanisms. The Protocol’s explicit provisions on ratification, accession, and reservations under Articles 8 and 2(1) provide a transparent framework for states to commit to abolition while accommodating specific national circumstances (United Nations, 1989). This clarity can inform other human rights treaties by ensuring that entry processes are accessible and legally precise, encouraging broader participation.

Second, the Protocol’s monitoring mechanisms, overseen by the Human Rights Committee, demonstrate the value of accountability in treaty implementation. States considering entry into similar instruments can learn from this model, ensuring that ratification is accompanied by robust domestic mechanisms for compliance. For State X, adopting such mechanisms would involve not only legislative changes but also independent oversight bodies to monitor the abolition process and address violations.

Finally, the Protocol’s gradual but steady increase in state parties—from its initial entry into force with 10 ratifications in 1991 to 92 by 2024—underscores the role of sustained advocacy and international cooperation in treaty expansion (Wikipedia, 2024). Peer influence, regional human rights systems (e.g., the European Court of Human Rights), and civil society engagement have all contributed to this growth, providing a blueprint for other treaties aiming to advance contentious human rights issues.

Challenges and Criticisms

While the Second Optional Protocol is a pivotal instrument, it is not without challenges and criticisms. One major critique is its limited scope due to the optional nature of the treaty. States with entrenched practices of capital punishment often opt out, reducing the Protocol’s universality. Additionally, the reservation clause under Article 2(1) has been criticized for diluting the commitment to total abolition, as it allows exceptions during wartime, even if only a few states, such as Azerbaijan and Greece, currently retain such reservations (United Nations, 1989; Wikipedia, 2024).

Another challenge lies in enforcement. The Protocol lacks a mechanism for sanctions or penalties against non-compliant states, relying instead on moral suasion and periodic reporting to the Human Rights Committee. This soft enforcement approach may be insufficient in contexts where domestic political will is lacking or where executions are carried out covertly (Hood & Hoyle, 2015).

Furthermore, cultural and religious arguments often underpin resistance to abolition, with some states viewing the death penalty as a legitimate form of justice or deterrence. Addressing these deeply rooted perspectives requires not only legal reforms but also cultural dialogue and education, areas where the Protocol offers limited guidance. For State X, navigating these cultural dimensions would be critical to successful implementation, potentially requiring partnerships with local civil society to build public support for abolition.

Conclusion

The Second Optional Protocol to the International Covenant on Civil and Political Rights stands as a beacon in the global movement to abolish the death penalty, advancing human rights by prioritizing the right to life and human dignity. Through its clear legal obligations and alignment with international treaty-making principles under the VCLT, it provides a structured pathway for states like State X to commit to abolition, whether through a monist or dualist approach to treaty implementation. Its impact is evident in the growing number of state parties, domestic legal reforms, and the normative shift against capital punishment, though challenges remain in achieving universal abolition.

For State X and other countries, the Protocol offers a model of how to enter into human rights treaties with transparency and accountability, guided by international legal norms. While its relationship with the VCLT underscores the procedural rigor of treaty-making, its practical success hinges on domestic commitment and cultural transformation. As the global human rights landscape evolves, the Second Optional Protocol will continue to play a central role in advocating for a world free from the death penalty, inspiring states to align their laws and values with the universal principles of life and dignity.
