Introduction
International dispute settlement mechanisms form a cornerstone of public international law, aiming to resolve conflicts between states through peaceful means such as adjudication, arbitration, and negotiation. These mechanisms, including the International Court of Justice (ICJ), the World Trade Organization (WTO) Dispute Settlement Body, and various arbitral tribunals, are designed to uphold principles of equality and justice as enshrined in the United Nations Charter. However, a persistent critique argues that these systems inherently favour powerful states, perpetuating inequalities rooted in economic, political, and military disparities. This essay critically discusses this proposition from the perspective of Tanzanian public international law, drawing on Tanzania’s experiences as a developing African nation. By examining the structural biases in these mechanisms, their application in practice, and specific Tanzanian cases, the essay will argue that while some favouritism towards powerful states exists, mechanisms can also empower weaker states through strategic engagement. The discussion will proceed with an overview of key mechanisms, an analysis of power dynamics, Tanzania’s contextual experiences, and a critical evaluation, ultimately highlighting implications for equitable international law.
Overview of International Dispute Settlement Mechanisms
Public international law provides several avenues for resolving disputes between states, primarily to maintain global peace and security. The ICJ, established under Article 92 of the UN Charter, serves as the principal judicial organ for contentious cases and advisory opinions (Shaw, 2017). It operates on the basis of consent, where states must accept its jurisdiction, often through optional clause declarations under Article 36(2) of the ICJ Statute. Arbitration, another key mechanism, involves ad hoc or institutional processes like those under the Permanent Court of Arbitration (PCA), allowing parties flexibility in rules and arbitrators. Additionally, specialised bodies such as the WTO’s Dispute Settlement Understanding (DSU) address trade disputes, enforcing decisions through retaliation authorisation if necessary (Bossche and Zdouc, 2017).
These mechanisms are theoretically grounded in sovereign equality, as articulated in Article 2(1) of the UN Charter, which posits that all states are juridically equal regardless of size or power. However, practical implementation reveals limitations. For instance, enforcement relies heavily on voluntary compliance, as the ICJ lacks direct coercive powers, often leading to non-compliance by defiant states (Posner and Yoo, 2005). In the context of Tanzania, a state party to the UN Charter since 1961, these mechanisms are integrated into its domestic legal framework through the Constitution of the United Republic of Tanzania (1977, as amended), which recognises international law under Article 63(3)(e). Tanzania has engaged with these systems, for example, in boundary disputes and investment arbitrations, reflecting its commitment to peaceful resolution while navigating challenges as a less powerful actor.
Furthermore, regional mechanisms like the African Court on Human and Peoples’ Rights (ACHPR) and the East African Court of Justice (EACJ) provide supplementary avenues, often more accessible to African states. Tanzania’s withdrawal of its declaration under Article 34(6) of the ACHPR Protocol in 2019 illustrates tensions between national sovereignty and international oversight (Viljoen, 2019). This overview underscores that while mechanisms aim for impartiality, their effectiveness can be undermined by power imbalances, setting the stage for a deeper critical analysis.
The Influence of Power in International Dispute Settlement
A central argument in international law scholarship is that dispute settlement mechanisms disproportionately benefit powerful states due to inherent structural biases. Powerful states, often characterised by economic dominance and veto powers in bodies like the UN Security Council, can influence outcomes through agenda-setting, resource allocation, and enforcement leverage. For example, in ICJ proceedings, wealthier states can afford extensive legal teams and research, potentially swaying judgments through superior argumentation (Posner and Yoo, 2005). This is evident in cases like the Nicaragua v. United States (1986), where the U.S. ignored an adverse ICJ ruling, demonstrating how powerful states can evade accountability without significant repercussions.
Critically, however, not all mechanisms exhibit this bias uniformly. The WTO DSU, for instance, has enabled developing states to challenge powerful economies successfully. Brazil’s victory against the U.S. in the cotton subsidies dispute (2004) illustrates how rule-based systems can level the playing field, with enforcement through authorised trade sanctions (Bossche and Zdouc, 2017). Yet, even here, limitations persist: weaker states may lack the capacity to retaliate effectively, rendering wins pyrrhic. In arbitration, investor-state dispute settlement (ISDS) under bilateral investment treaties (BITs) often favours corporate interests from powerful states, as seen in critiques of the International Centre for Settlement of Investment Disputes (ICSID), where developing host states face asymmetrical bargaining power (Salacuse, 2015).
From a theoretical perspective, realism in international relations posits that law serves the interests of the powerful, with institutions reflecting hegemonic preferences (Morgenthau, 1948). Conversely, liberal institutionalism argues that mechanisms foster cooperation, benefiting all through mutual gains (Keohane, 1984). This dichotomy highlights a nuanced reality: while power influences access and outcomes, procedural safeguards like third-party adjudication can mitigate biases. Indeed, the increasing participation of developing states in ICJ cases—rising from 20% in the 1950s to over 40% in recent decades—suggests a gradual democratisation, though enforcement gaps remain (Shaw, 2017). Therefore, while favouritism exists, it is not absolute, and strategic alliances can empower smaller states.
Tanzania’s Experiences in International Dispute Settlement
Tanzania’s engagement with international dispute mechanisms provides a practical lens to assess power dynamics, particularly as a developing state in East Africa. As a former British colony independent since 1961, Tanzania has navigated public international law through a dualist system, incorporating treaties via domestic legislation. A notable example is the Lake Malawi (Nyasa) border dispute with Malawi, initiated in 2012 and mediated through the Southern African Development Community (SADC). Tanzania argued for a median line boundary based on colonial treaties, while Malawi claimed the entire lake under uti possidetis principles (Kruger, 2018). Although unresolved, this case exemplifies how weaker states like Tanzania can leverage regional mechanisms to counter more influential neighbours, avoiding escalation to the ICJ where power asymmetries might be more pronounced.
In investment disputes, Tanzania has faced challenges under ISDS. The 2018 ICSID case brought by Australian mining company Indiana Resources against Tanzania over the revocation of retention licences highlights perceived biases. Tanzania, invoking national resource sovereignty, argued against arbitration clauses in BITs that favour foreign investors from powerful states (ICSID Case No. ARB/18/2). The tribunal’s jurisdiction was upheld, but Tanzania’s subsequent legislative reforms, including the Natural Wealth and Resources Contracts Act (2017), aimed to renegotiate unfair terms, reflecting resistance to mechanisms that arguably prioritise capital-exporting nations (Muchlinski, 2021). Critically, this demonstrates how powerful states’ investors benefit from enforcement, while host states like Tanzania incur high costs—estimated at millions in legal fees—potentially deterring future engagements.
Moreover, Tanzania’s involvement in the ICJ is limited but instructive. It has not submitted to compulsory jurisdiction, preferring ad hoc consent, as seen in its advisory opinion requests through the UN General Assembly. The Chagos Archipelago advisory opinion (2019), while not directly involving Tanzania, resonated with African states, including Tanzania, which supported Mauritius against the UK, a powerful state, illustrating collective action against colonial legacies (ICJ, 2019). However, Tanzania’s 2019 withdrawal from ACHPR individual access underscores sovereignty concerns, arguably a response to perceived overreach by international bodies influenced by Western powers (Viljoen, 2019). These experiences reveal that while mechanisms can favour powerful states through resource advantages and non-compliance, Tanzania has utilised diplomacy and reforms to assert agency, though with varying success.
Critical Analysis of Power Asymmetries and Reforms
Critically evaluating the favouritism thesis, it is evident that international dispute mechanisms embody both enabling and constraining elements for weaker states like Tanzania. On one hand, systemic biases are apparent: powerful states dominate norm-creation, as in the drafting of the Vienna Convention on the Law of Treaties (1969), where developing states had limited input (Sinclair, 1984). Enforcement disparities further compound this; for instance, the U.S. withdrawal from ICJ jurisdiction post-Nicaragua contrasts with smaller states’ inability to similarly disengage without isolation. In Tanzanian context, this manifests in trade disputes, where reliance on WTO mechanisms against EU agricultural subsidies disadvantages local farmers, perpetuating economic inequality (Kruger, 2018).
However, counterarguments suggest mechanisms offer opportunities for empowerment. The principle of pacta sunt servanda ensures binding commitments, and successes like Antigua’s WTO win against U.S. gambling restrictions (2007) show that even small states can prevail through legal ingenuity (Bossche and Zdouc, 2017). For Tanzania, participation in the African Continental Free Trade Area (AfCFTA) dispute protocols could enhance bargaining power regionally, mitigating global asymmetries. Nonetheless, limitations in capacity—such as limited legal expertise and funding—hinder full utilisation, pointing to the need for reforms like capacity-building initiatives from the UN Conference on Trade and Development (UNCTAD).
Arguably, the favouritism is not inherent but contextual, influenced by geopolitical shifts. The rise of multipolarity, with powers like China offering alternative dispute forums through the Belt and Road Initiative, could diversify options for states like Tanzania, which has deepened ties with China (Salacuse, 2015). Yet, this raises concerns of new dependencies. Overall, while mechanisms favour powerful states through structural advantages, critical reforms—such as enhancing enforcement equity and inclusivity—could foster greater parity, benefiting Tanzania’s pursuit of sustainable development under international law.
Conclusion
In summary, international dispute settlement mechanisms do exhibit tendencies to favour powerful states, driven by resource disparities, enforcement gaps, and historical biases, as critically discussed through Tanzanian lenses. Examples from ICJ cases, WTO disputes, and Tanzania’s border and investment experiences illustrate these imbalances, yet also reveal avenues for weaker states to navigate and challenge them. The implications are profound: without reforms addressing power asymmetries, mechanisms risk undermining public international law’s legitimacy, particularly for developing nations like Tanzania. Ultimately, fostering inclusive, capacity-enhancing reforms could promote a more equitable system, aligning with Tanzania’s constitutional embrace of international norms and contributing to global justice. This analysis underscores the need for ongoing critical engagement to balance power in dispute resolution.
