CDEDI presses Parliament to summon security bosses over Tanzanian vessel

A recent incident involving an unauthorised Tanzanian vessel in Malawi's territorial waters on Lake Malawi has prompted the governance watchdog, CDEDI, to call for Parliament to summon security chiefs. This development highlights critical legal issues surrounding Malawi's territorial sovereignty, national security protocols, and the efficacy of parliamentary oversight. The incident underscores the long-standing border dispute between Malawi and Tanzania over Lake Malawi, where differing interpretations of colonial treaties and international law persist. For legal practitioners, the event raises questions about the application of maritime law in internal waters, the constitutional mandate of security agencies, and Parliament's role in ensuring accountability for breaches of national security and territorial integrity.

The unauthorised entry of a Tanzanian vessel into Malawi’s territorial waters on Lake Malawi has ignited a significant legal and political debate, drawing the attention of the Centre for Democracy and Economic Development Initiatives (CDEDI). The governance watchdog has formally petitioned the Malawian Parliament to summon security bosses, demanding an explanation for what it describes as a serious breach of national security and territorial integrity. This incident has not only caused public alarm but also brought to the fore a complex interplay of international law, domestic constitutional mandates, and a protracted bilateral dispute over the demarcation of the Lake Malawi/Nyasa boundary. The legal implications extend beyond mere border control, touching upon the very essence of state sovereignty and the accountability of state organs.

This article aims to dissect the legal ramifications of this incident for practising attorneys and legal professionals in Malawi. It will explore the statutory and doctrinal context governing Malawi's territorial waters, particularly within the contested framework of Lake Malawi. Furthermore, it will analyse the constitutional powers vested in the Malawian Parliament to oversee security agencies and hold them accountable, juxtaposing these against the backdrop of international maritime law principles. The incident serves as a critical case study for understanding the challenges in enforcing national security in shared water bodies and the imperative for robust legislative oversight.

Malawi's claim to its territorial waters on Lake Malawi (known as Lake Nyasa in Tanzania) is rooted in the 1890 Anglo-German (Heligoland-Zanzibar) Treaty, which Malawi asserts establishes the boundary along the Tanzanian shoreline, effectively placing the entire lake within Malawian sovereignty. This position is vehemently disputed by Tanzania, which advocates for a median line boundary, citing international norms and practices, including Article 15 of the United Nations Convention on the Law of the Sea (UNCLOS), which generally prescribes a median line for shared water bodies unless a specific agreement dictates otherwise. The dispute, which has historical colonial origins, re-escalated in the 2010s following the awarding of hydrocarbon exploration licenses by Malawi, underscoring the economic and strategic importance of the lake.

Despite being a landlocked country, Malawi possesses significant internal waters, with Lake Malawi stretching approximately 570 kilometres and serving as a vital navigable waterway. The Constitution of the Republic of Malawi, in its foundational provisions, affirms that the national territory includes "airspace, waters and islands which comprised the territory of Malawi before the commencement of this Constitution," thereby enshrining the existing territorial claims. The legal framework for maritime activities on these internal waters is partly governed by the Inland Waters Shipping Act (Cap. 71:01). This historical and legal context forms the bedrock upon which any unauthorised entry into these contested waters must be assessed.

The unauthorised entry of a Tanzanian vessel directly challenges Malawi's asserted sovereignty over its territorial waters on Lake Malawi. The Defence Forces of Malawi are constitutionally mandated to "uphold the sovereignty and territorial integrity of the Republic and guard against threats to the safety of its citizens by force of arms." A breach of these waters, particularly by a vessel from a neighbouring state with a competing claim, constitutes a direct affront to this mandate and raises serious questions about the effectiveness of border security. The Malawi Police Service, established under sections 152 and 153 of the Constitution, is tasked with the "protection of public safety and the rights of persons in Malawi" and the "maintenance of law and order," which implicitly includes controlling entry and exit points.

From an international law perspective, while UNCLOS primarily governs maritime zones in the open sea, its principles on innocent passage are instructive. Article 19 of UNCLOS defines passage as innocent so long as it is not prejudicial to the peace, good order, or security of the coastal state. Activities such as any threat or use of force, weapons exercises, or collecting information prejudicial to defence would render passage non-innocent. An unauthorised entry, particularly in a disputed area, would almost certainly be considered non-innocent, granting Malawi the right to take necessary steps to prevent such passage. The complexity arises from Tanzania's invocation of UNCLOS Article 15 for a median line, which Malawi counters by asserting the primacy of the 1890 treaty as a specific agreement.

The call by CDEDI for Parliament to summon security chiefs underscores the critical role of legislative oversight in a democratic state. The Constitution of Malawi empowers the National Assembly to oversee the Executive, including the military and security services. Specifically, the Defence and Security Committee of the National Assembly holds oversight authority over the Defence Forces, and Parliament generally has the power to summon members of government for accountability. This constitutional mandate allows Parliament to investigate, scrutinise, and even censure any branch of government operating outside the bounds of the law. The incident highlights a potential gap in Malawi's overarching national security strategy, which has historically been criticised for lacking a comprehensive framework beyond broad constitutional mandates and political directives, leading to concerns about transparency and accountability within security services.

The effectiveness of parliamentary committees, such as the Defence and Security Committee, the Legal Affairs Committee, and the Public Appointments Committee, in actively interrogating misconduct and preventing systemic abuse is paramount. Their ability to conduct transparent inquiries and demand answers from security agencies is crucial for maintaining public trust and ensuring that state institutions operate within the rule of law. Failure to exercise this oversight robustly could embolden impunity and erode democratic principles, as highlighted by concerns regarding Parliament's past inaction on security force conduct.

The unauthorised entry of a Tanzanian vessel into Malawian waters on Lake Malawi is a multifaceted legal and geopolitical challenge, deeply intertwined with the unresolved border dispute and fundamental questions of national security. For legal practitioners, this incident serves as a stark reminder of the complexities inherent in applying international maritime law principles to internal waters, particularly where historical treaties and contemporary norms clash. It necessitates a meticulous understanding of both domestic constitutional provisions, such as those defining Malawi's territory and the mandates of its security forces, and the nuances of international conventions like UNCLOS.

The imperative for the Malawian Parliament to exercise its constitutional oversight functions cannot be overstated. Summoning security chiefs is not merely a political act but a vital mechanism for ensuring accountability, transparency, and the restoration of public confidence in the state's ability to protect its sovereignty and citizens. This incident should prompt a comprehensive review of Malawi's maritime security protocols for Lake Malawi and potentially catalyse renewed diplomatic efforts to resolve the long-standing border dispute with Tanzania. Legal professionals should closely monitor parliamentary proceedings and any subsequent policy or legislative reforms, as these will shape the future landscape of national security and territorial integrity enforcement in Malawi's critical internal waters.
