Introduction

Bosnia and Herzegovina (BiH), a country in Southeastern Europe with a complex political structure rooted in the aftermath of the 1992-1995 war, operates under a unique constitutional framework that shapes its engagement with international agreements. The Constitution of Bosnia and Herzegovina, established as Annex 4 of the Dayton Peace Agreement in 1995, delineates the powers and responsibilities of the state and its entities concerning international relations, including the conclusion of treaties. This article examines how BiH navigates international agreements under its Constitution and existing international conventions, with a focus on the legal mechanisms for entering into treaties, the monist or dualist nature of its approach to international law, the process of incorporating treaties into national law, and its relationship with the Vienna Convention on the Law of Treaties (VCLT) of 1969. Through this analysis, the article aims to provide insights for other states on engaging in treaty-making with BiH, considering the peculiarities of its decentralized political system and historical context.

Constitutional Framework for Treaty-Making in Bosnia and Herzegovina

The Constitution of Bosnia and Herzegovina establishes a complex governance structure comprising two entities—the Federation of Bosnia and Herzegovina (FBiH) and the Republika Srpska (RS)—and the Brčko District, with powers distributed between the central state and these entities. The authority to engage in international agreements is primarily vested in the central state institutions, though the entities have some limited competencies in this regard under specific conditions. This section explores the relevant constitutional provisions that govern BiH’s ability to enter into treaties, highlighting the legal basis for state action in international law.

Article I(3) of the Constitution of Bosnia and Herzegovina explicitly states that “Bosnia and Herzegovina shall remain or become party to international agreements in effect at the time this Constitution comes into force or signed thereafter by its authorized representatives” (Constitution of Bosnia and Herzegovina, 1995). This provision establishes the state’s continuity in international obligations inherited from the former Socialist Federal Republic of Yugoslavia (SFRY) and affirms its capacity to enter into new treaties post-1995. As a successor state to the SFRY, BiH assumed certain treaty obligations under the principle of state succession, a process overseen by the central authorities in coordination with international bodies.

More specifically, the responsibility for conducting foreign policy and entering into international agreements is assigned to the central state institutions under Article III(2)(a), which designates foreign policy as a responsibility of the institutions of Bosnia and Herzegovina. The Presidency of Bosnia and Herzegovina, as the collective head of state, plays a central role in treaty-making. According to Article V(3)(a), the Presidency is tasked with representing BiH in international and European organizations and institutions, as well as negotiating and, with the consent of the Parliamentary Assembly, ratifying treaties on behalf of the state (Constitution of Bosnia and Herzegovina, 1995). This indicates that treaty-making power is centralized at the state level, requiring consensus among the tripartite Presidency, which consists of one Bosniak, one Croat, and one Serb member, reflecting the country’s ethnic composition.

Moreover, Article IV(4)(e) of the Constitution grants the Parliamentary Assembly the authority to approve international agreements, ensuring legislative oversight in the treaty-making process. This dual requirement of Presidential negotiation and Parliamentary approval underscores a system of checks and balances designed to accommodate the diverse interests within BiH’s multi-ethnic society. However, the entities (FBiH and RS) are not entirely excluded from international engagement. Under Article III(2)(d), the entities may establish “special parallel relationships with neighboring states” with the consent of the central state institutions, and they may enter into agreements with states or international organizations provided such agreements are consistent with the sovereignty and territorial integrity of BiH (Constitution of Bosnia and Herzegovina, 1995). This limited competence reflects the decentralized nature of the state while prioritizing national unity in foreign affairs.

In practice, the process of entering into treaties involves multiple stages: negotiation by the Presidency, drafting and initialing of agreements, approval by the Council of Ministers (the executive body), and final ratification by the Parliamentary Assembly. The Ministry of Foreign Affairs often facilitates diplomatic engagement and ensures compliance with international norms. This structured process, while aimed at inclusivity and consensus, can be slow and contentious due to political disagreements among ethnic groups or between the entities and the central state. Nonetheless, the constitutional provisions provide a clear legal foundation for BiH to act as a sovereign state in the international arena, capable of entering into binding treaties under international law.

Monist or Dualist Approach: Bosnia and Herzegovina’s Stance on International Law

A critical aspect of understanding how BiH engages with international agreements is determining whether it adopts a monist or dualist approach to the incorporation of international law into its domestic legal system. In a monist system, international law is automatically part of domestic law and can be directly applied by national courts upon ratification of a treaty. In contrast, a dualist system requires explicit legislative action to transform international obligations into domestic law, treating international and national legal orders as separate.

Bosnia and Herzegovina operates under a predominantly monist approach, as evidenced by specific provisions in its Constitution and judicial interpretations. Article II(2) of the Constitution incorporates the European Convention for the Protection of Human Rights and Fundamental Freedoms (ECHR) and its Protocols directly into domestic law, stipulating that they “shall have priority over all other law” (Constitution of Bosnia and Herzegovina, 1995). This provision suggests that certain international agreements, particularly those related to human rights, are self-executing and take precedence over conflicting national legislation, a hallmark of monism. Furthermore, Annex I of the Constitution lists additional international human rights agreements that are directly applicable within BiH, reinforcing the prioritization of international norms in specific areas.

However, the monist tendency is not absolute and is nuanced by the country’s complex governance structure. For treaties outside the scope of human rights, the process of incorporation often requires additional legislative or regulatory action, indicating elements of dualism. For instance, while the Constitution grants priority to certain international agreements, the implementation of other treaties may necessitate enabling legislation by the Parliamentary Assembly or entity-level parliaments, depending on the subject matter and division of competencies. This hybrid approach is further complicated by the fact that entity-level constitutions (those of FBiH and RS) may not always align seamlessly with state-level obligations, leading to discrepancies in treaty implementation across different parts of the country.

The Constitutional Court of Bosnia and Herzegovina has played a significant role in clarifying the relationship between international and domestic law. In its landmark decision on the constituency of peoples (Case No. U-5/98), the Court interpreted the Constitution as a treaty governed by the principles of the Vienna Convention on the Law of Treaties of 1969, suggesting a strong inclination towards integrating international legal norms into the domestic framework. The Court’s rulings often emphasize the supremacy of constitutional and international human rights obligations over entity-level laws, further supporting a monist interpretation in critical areas (Constitutional Court of BiH, 2000).

In practical terms, treaties ratified by BiH are generally considered part of the domestic legal order upon ratification and publication in the Official Gazette of Bosnia and Herzegovina, without the need for separate legislation unless the treaty explicitly requires it or falls within entity competencies. According to legal scholars, this process reflects a “soft monism,” where international law is directly applicable in principle but may require practical measures for enforcement, particularly in areas like economic or trade agreements that intersect with entity powers (Softić, 2015). Thus, while BiH leans towards monism, particularly in human rights matters, elements of dualism persist due to its decentralized political system and the need for coordination between state and entity levels.

Incorporation of Treaties into National Law

The process by which international treaties are translated into national law in BiH reflects the country’s hybrid monist-dualist approach and its constitutional division of powers. As noted earlier, treaties are negotiated by the Presidency and must be ratified by the Parliamentary Assembly to become binding under international law. Once ratified, the treaty is published in the Official Gazette of Bosnia and Herzegovina, at which point it is generally considered part of the domestic legal system, particularly for treaties related to human rights as stipulated under Article II(2) and Annex I of the Constitution.

For treaties that fall within the competencies of the entities, such as those related to education, culture, or local economic matters, additional steps may be required. The entities must adopt corresponding legislation or regulations to ensure compliance with treaty obligations, as the central state lacks direct enforcement authority in these areas. This process can lead to delays or inconsistent application of treaties across the country, as the entities may interpret or prioritize international obligations differently based on political or ethnic considerations (Begić, 2017). For example, trade agreements or environmental treaties often require entity-level implementation, necessitating coordination between the central government and entity authorities.

The role of the judiciary in enforcing treaty obligations is also significant. The Constitutional Court of BiH has the authority to review the compatibility of domestic laws with international agreements, particularly those enshrined in the Constitution. Under Article VI(3), the Constitutional Court ensures that state and entity laws conform to constitutional principles, including international human rights standards, thereby acting as a mechanism for harmonizing domestic and international legal obligations (Constitution of Bosnia and Herzegovina, 1995). This judicial oversight reinforces the direct applicability of certain treaties, aligning with a monist perspective.

However, challenges remain in the effective incorporation of treaties due to the fragmented nature of BiH’s legal system. The lack of a unified legal framework across the state and entities often results in uneven implementation, with some treaties remaining unimplemented at the entity level despite ratification at the state level. Legal experts have noted that capacity constraints, political disagreements, and varying interpretations of constitutional competencies hinder the seamless integration of international agreements into national law (Marković, 2019). Addressing these challenges requires enhanced coordination mechanisms and greater political will to align entity practices with state-level commitments.

Bosnia and Herzegovina and the Vienna Convention on the Law of Treaties 1969

The Vienna Convention on the Law of Treaties (VCLT) of 1969 is widely regarded as the cornerstone of international treaty law, codifying customary rules on the formation, interpretation, amendment, and termination of treaties. Adopted on May 23, 1969, and entered into force on January 27, 1980, the VCLT provides a framework for states to engage in treaty-making in a consistent and predictable manner. This section examines whether BiH is a party to the VCLT and the implications of its status for other countries seeking to enter into treaties with BiH.

Bosnia and Herzegovina is not a formal party to the VCLT of 1969. As a successor state to the Socialist Federal Republic of Yugoslavia, which ratified the VCLT in 1970, BiH did not automatically assume all treaty obligations of the SFRY upon its independence in 1992. While BiH notified the United Nations of its succession to certain treaties of the SFRY, it has not explicitly acceded to or ratified the VCLT as an independent state. According to the United Nations Treaty Collection, BiH is not listed among the 116 states that have ratified the Convention as of the latest available data (United Nations Treaty Collection, 2023).

Despite not being a party to the VCLT, BiH is bound by many of its provisions under customary international law. The VCLT is often recognized as a codification of customary rules, and even non-party states, including BiH, adhere to its principles in their treaty practices. For instance, the Constitutional Court of BiH has referenced the VCLT in its interpretations of the Constitution as a treaty under international law, particularly in the context of the Dayton Agreement (Constitutional Court of BiH, 2000). This suggests that BiH implicitly accepts key VCLT principles, such as pacta sunt servanda (treaties must be observed in good faith) and rules on treaty interpretation, as part of customary international law.

The non-party status of BiH to the VCLT has several implications for other states engaging in treaty-making with the country. First, while BiH generally follows customary treaty law, there may be deviations or unique procedural requirements stemming from its internal constitutional structure that are not explicitly addressed by the VCLT. Other states should therefore ensure that treaty negotiations account for BiH’s decentralized system and the need for consensus among its central and entity-level authorities. For example, treaties requiring entity-level implementation may face delays or require additional agreements with FBiH or RS, even if ratified at the state level.

Second, the absence of formal adherence to the VCLT means that BiH may not be bound by specific procedural or interpretative rules of the Convention unless they are deemed customary. Other states should prioritize clarity in treaty drafting, explicitly addressing issues such as dispute resolution, amendment procedures, and termination conditions to avoid potential misunderstandings. Engaging BiH’s Ministry of Foreign Affairs early in the process can help navigate these intricacies and ensure compliance with both international norms and domestic requirements.

Finally, BiH’s historical context and reliance on international agreements as part of its peace-building process (e.g., the Dayton Agreement) highlight the importance of international law in its governance. Other states can leverage this by aligning treaty proposals with BiH’s international commitments, particularly those related to European integration or human rights, to facilitate consensus and ratification. While not a party to the VCLT, BiH’s treaty practices remain influenced by its principles, providing a predictable foundation for international cooperation if approached with an understanding of the country’s unique political landscape.

Challenges and Opportunities in Treaty Engagement with Bosnia and Herzegovina

Engaging in treaties with Bosnia and Herzegovina presents both challenges and opportunities due to its complex constitutional structure and political dynamics. One significant challenge is the potential for political gridlock in the treaty-making process. The need for consensus among the tripartite Presidency and approval by the Parliamentary Assembly often results in delays, particularly for treaties touching on sensitive ethnic or political issues. Additionally, the division of competencies between the state and entities can create uncertainties regarding implementation, as entities may resist or delay adopting necessary legislation to give effect to treaties (Hodžić, 2020).

Another challenge lies in the inconsistent application of international agreements across BiH’s territory. The lack of a unified legal system means that treaty obligations may be enforced differently in FBiH, RS, and Brčko District, depending on local political priorities and capacities. This fragmentation can frustrate international partners seeking uniform compliance with treaty terms, particularly in areas like trade, environmental protection, or security cooperation. Addressing this requires targeted capacity-building efforts and diplomatic engagement with both state and entity authorities to ensure alignment.

Despite these challenges, there are significant opportunities for effective treaty engagement with BiH. The country’s commitment to European integration, as evidenced by its candidate status for European Union membership, provides a strong incentive for aligning its legal framework with international standards. Treaties that support EU accession goals, such as those related to governance reform, economic cooperation, or human rights, are likely to receive broad support within BiH’s institutions. International partners can capitalize on this by framing agreements within the context of Europeanization, thereby increasing the likelihood of swift ratification and implementation.

Furthermore, BiH’s reliance on international agreements as a tool for post-conflict stabilization offers a unique avenue for engagement. The Dayton Agreement itself, which serves as the foundation of BiH’s Constitution, underscores the importance of international law in maintaining peace and stability. Treaties that reinforce peace-building, reconciliation, or regional cooperation are likely to resonate with BiH’s leadership and public, providing a basis for stronger bilateral or multilateral partnerships.

Recommendations for International Partners

Based on the foregoing analysis, several recommendations can be offered to states and international organizations seeking to enter into treaties with Bosnia and Herzegovina. First, partners should adopt a proactive approach to understanding BiH’s constitutional framework and political dynamics. Engaging with the Ministry of Foreign Affairs and other relevant state institutions early in the negotiation process can help identify potential obstacles and ensure that treaty terms account for the need for entity-level involvement where applicable.

Second, treaty drafting should emphasize clarity and specificity to mitigate risks associated with BiH’s non-party status to the VCLT. Explicit provisions on implementation timelines, dispute resolution mechanisms, and monitoring frameworks can help bridge gaps in domestic enforcement capacity and reduce the likelihood of misinterpretation. Additionally, providing technical assistance or capacity-building support for treaty implementation at both state and entity levels can enhance compliance and foster goodwill.

Third, international partners should align treaty proposals with BiH’s broader strategic goals, particularly its aspirations for EU membership and regional stability. Framing agreements within these contexts can build consensus among BiH’s diverse political actors, facilitating smoother ratification and implementation processes. Finally, patience and diplomatic persistence are essential, given the potential for delays due to internal political disagreements. Sustained engagement and dialogue can help overcome these hurdles and build long-term partnerships grounded in mutual trust.

Conclusion

Bosnia and Herzegovina navigates the complex landscape of international agreements through a constitutional framework that centralizes treaty-making authority at the state level while accommodating limited entity involvement. Its predominantly monist approach, tempered by elements of dualism due to its decentralized structure, shapes the incorporation of treaties into national law, with human rights agreements enjoying direct applicability and others often requiring additional legislative action. Although not a party to the Vienna Convention on the Law of Treaties of 1969, BiH adheres to many of its principles as customary international law, providing a basis for predictable treaty engagement despite procedural and political challenges.

For other states, engaging in treaties with BiH requires a nuanced understanding of its legal and political systems, as well as strategic alignment with its international priorities. While challenges such as political gridlock and inconsistent implementation persist, opportunities exist to leverage BiH’s commitment to European integration and peace-building as a foundation for successful agreements. By adopting a patient, informed, and collaborative approach, international partners can navigate the intricacies of treaty-making with BiH, contributing to both bilateral objectives and the broader goals of regional stability and development.
