The practical lesson for East Africa

Environmental cases are often remembered for their final remedy. The Serengeti road litigation deserves a more careful reading because its most useful lesson begins before the merits were decided. The East African Court of Justice first had to determine whether a Treaty based environmental reference could survive objections about jurisdiction, procedure and the form of the pleadings.

The answer mattered beyond one proposed road. If a Partner State could defeat a regional environmental claim by describing the project as domestic infrastructure or by postponing scrutiny until after construction, the EAC Treaty duties on ecosystems and natural resources would be difficult to enforce. If every early idea were immediately treated as a justiciable action, courts could be drawn into abstract policy disputes.

Attorney General of Tanzania v African Network for Animal Welfare (ANAW) occupies that narrow space. It protects the Court's ability to enforce the Treaty, while insisting that remedies follow jurisdiction and evidence. That combination explains why the judgment remains useful to governments, communities, lawyers and environmental organisations across East Africa.

Why this appeal matters

Appeal No. 3 of 2011 is often remembered as the Serengeti road case. That description is understandable, but incomplete. The judgment delivered on 15 March 2012 did not finally determine whether the proposed road violated the East African Community Treaty. It decided whether the environmental reference could proceed past preliminary objections and whether the Appellate Division could be asked to decide questions that properly belonged to the First Instance Division.

That procedural character does not make the decision unimportant. The Court gave practical meaning to the Treaty provisions on environmental protection, sustainable use of natural resources, infrastructure and regional cooperation. Read with the later ANAW judgments, it forms a binding environmental line that tells governments to design infrastructure within, rather than outside, the legal duties they accepted through regional integration.

The case and citation

The full citation is The Honourable Attorney General of the United Republic of Tanzania v African Network for Animal Welfare (ANAW), Appeal No. 3 of 2011, Judgment of the Appellate Division of the East African Court of Justice at Arusha, 15 March 2012. The judgment was delivered by Harold R. Nsekela, President, with Emily R. Kayitesi and James Ogoola, Justices of Appeal. The judgment is unanimous and records no dissenting opinion.

The appeal arose from Reference No. 9 of 2010, filed by ANAW against the Government of Tanzania. ANAW challenged the proposed upgrading, construction or commissioning of the Natta-Mugumu-Tabora B-Klein's Gate-Loliondo road, also called the North Road or Serengeti Superhighway, across Serengeti National Park. It sought a declaration that the proposed action infringed the Treaty and a permanent injunction restraining construction.

Tanzania's Attorney General raised six preliminary objections. They included limitation, defective enabling provisions, uncertainty about whether the case was a Reference or Notice of Motion, defects in the supporting affidavit, lack of jurisdiction or power to grant a permanent injunction against a Partner State, and the alleged joining of different applications. The First Instance Division overruled the objections, and the Attorney General appealed.

The legal question before the court

The central issue was whether the First Instance Division had wrongly allowed the reference to continue. More precisely, the Appellate Division had to decide whether the objections raised pure questions of law capable of ending the case at the threshold, whether the EACJ had Treaty jurisdiction over an environmental dispute involving a Partner State, whether the confusion in the originating papers was fatal, and whether the Appellate Division could reassess matters that depended on evidence and factual findings.

The issue was not whether Tanzania had already constructed the road, nor whether the road was finally unlawful. It was also not a final decision on the merits of the environmental evidence. The Court repeatedly separated the existence of power from the eventual exercise of a remedy. A court may have power to grant an injunction, yet still decline to grant it after hearing the evidence. That distinction became decisive because the Attorney General's complaint about a permanent injunction was premature at the preliminary stage.

What the court held

The Court dismissed all grounds of appeal and remitted the matter to the First Instance Division for substantive trial and adjudication of the reference. It held that the Appellate Division could not decide the merits by treating factual disputes as preliminary points. Under Article 35A of the Treaty, an appeal lies on points of law, lack of jurisdiction or procedural irregularity. Questions of fact are for the First Instance Division and are not to be reargued as if the Appellate Division were hearing the case for the first time.

The Court also explained that jurisdiction and relief are different questions. Jurisdiction concerns the authority to hear the dispute. The power to issue a remedy concerns what the Court may do after it has jurisdiction and after the merits have been proved. The First Instance Division had not issued the feared permanent injunction when it ruled on the objections. The challenge to that remedy was therefore speculative and could not dispose of the reference at the beginning of the trial.

On the environmental question, the Court found a sufficient legal connection between ANAW's allegations and the Treaty. It referred to Articles 5(2), 5(3)(c), 8(1)(c), 111, 112 and 114. Article 5 requires harmonious and balanced development and sustainable use of natural resources. Article 8 requires Partner States to avoid measures likely to jeopardise the Treaty objectives. Article 111 addresses cooperation, information and early consultation where activities may have significant transboundary impacts. Articles 112 and 114 develop the cooperative duties concerning ecosystems and natural resources.

The Court gave the Treaty a purposive interpretation. It reasoned that the environmental obligations were part of the Treaty already in force and could not be made practically meaningless by a narrow reading. The absence of an environmental protocol did not prevent the Court from interpreting and applying existing Treaty provisions. The Treaty itself, together with the Court's jurisdiction under Articles 23, 27 and 30, supplied a legal basis for examining whether a Partner State had complied with its obligations.

The Court treated the filing confusion more generously. The papers were headed as a Reference and contained the substance required for a Reference, even though they also used the language of a Notice of Motion and included an affidavit. The Attorney General could not show substantial prejudice. The Court therefore refused to let an ambiguity in its own rules defeat a case that had given the respondent sufficient notice of the complaint and relief sought.

The binding rule of law

The principal rule is that the EACJ must independently determine its jurisdiction from the Treaty and may hear a Treaty-based environmental reference against a Partner State. A party's concession cannot create jurisdiction, but a State's sovereign status does not remove it from obligations voluntarily assumed under the Treaty. The Court's environmental jurisdiction is therefore part of the ordinary work of interpreting and enforcing regional law.

A second rule is that a preliminary objection must be a genuine point of law capable of disposing of the case without resolving disputed facts or weighing evidence. If an objection requires witnesses, documents, factual assessment or a conclusion about environmental effects, it belongs to the substantive hearing. A third rule is that the Appellate Division is not a second trial court on facts. Its role is controlled by Article 35A, and an appellant cannot use a legal label to reopen factual matters reserved for the First Instance Division.

A fourth rule concerns Treaty interpretation. Development and environmental protection are not separate legal compartments. The duty to support infrastructure and the duty to protect natural resources must be read together. A road may be economically useful and still be unlawful if its design or implementation disregards the regional obligations that protect ecosystems and neighbouring Partner States.

Why the decision matters for infrastructure

The decision matters because infrastructure often begins with language that sounds harmless: a proposal, feasibility study, corridor, strategic plan or preliminary design. The Court did not say that every policy idea is immediately justiciable. The later appellate merits judgment clarified that Article 30 requires a live and sufficiently concrete action, not a purely abstract wish. But the 2012 judgment prevents governments from using procedural objections to block scrutiny once a real Treaty question has been properly pleaded.

The case also shows why transboundary environmental effects change the legal analysis. Serengeti is within Tanzania, but the ecosystem is connected to Kenya's Maasai Mara and is recognised internationally. Article 111(1)(d)'s emphasis on timely information and early consultation is therefore not a decorative statement. It directs Partner States to think about neighbouring ecosystems and communities before a project becomes politically or financially difficult to change.

Tanzania's Environmental Management Act 2004 and National Environmental Policy 2021 provide important domestic tools for environmental assessment, biodiversity protection and sustainable development. They do not, however, replace the EAC Treaty. A national environmental approval may be relevant evidence of compliance, but it cannot by itself answer a regional claim based on transboundary effects, Treaty objectives or the obligations of cooperation. The stronger legal approach is cumulative: national assessment, public and expert participation, cross-border consultation and direct compliance with the Treaty.

Comparative environmental lessons

Kenya provides the closest comparison because the Serengeti ecosystem continues across the Tanzania-Kenya border. Articles 42, 69 and 70 of the Constitution of Kenya recognise environmental rights and duties and provide a route for enforcement. The Environmental Management and Co-ordination Act 1999 supplies the statutory framework for environmental impact assessment. In Save Lamu and 5 Others v National Environmental Management Authority and Another, the National Environmental Tribunal treated meaningful public participation as a central part of environmental assessment and cancelled an approval where the process was inadequate. The practical lesson is similar to ANAW: a project is not legally safe merely because it promises electricity, roads, jobs or regional growth; the decision maker must show that the required process was real and informed.

Uganda's National Environment Act 2019 and the National Environment Environmental and Social Assessment Regulations 2020 likewise place assessment and environmental conditions inside the project cycle. The Uganda Wildlife Act 2019 requires environmental impact assessment and related studies before certain protected areas or wildlife decisions are made. Rwanda's Law No. 48 of 2018 on Environment and the Strategic Environmental Assessment procedures under Ministerial Order No. 002/2021 illustrate the same institutional direction: development planning must carry environmental information early enough to affect the decision. These national examples are not direct holdings in ANAW, but they show how the Treaty principle can be implemented through domestic institutions.

The regional comparison is also visible in James Katabazi and 21 Others v Secretary General of the East African Community and Attorney General of Uganda, Reference No. 1 of 2007. That case recognised that conduct framed as a domestic dispute could also raise a distinct Treaty cause of action based on rule of law and good governance. ANAW applies the same structural insight to the environment. The national road decision is not insulated from regional review simply because it is made within national territory when the Treaty itself regulates cooperation, ecosystems and cross-border effects.

Counsel strategy and practical advocacy

ANAW's litigation strategy worked because it tied the environmental complaint to precise Treaty provisions rather than presenting conservation as a general appeal to sympathy. The record showed a legal nexus between the proposed road and Articles 5, 8, 111, 112 and 114. That pleading gave the Court a Treaty question to interpret. In the later merits appeal, ANAW's counsel, Kanchory Mbalela Saitabao, also successfully argued that the Attorney General was trying to raise a new factual point about a mere proposal after failing to plead and prove it at the proper stage.

The Attorney General's arguments were not irrational. Counsel Gabriel Pascal Malata argued that the Court should not entertain a hypothetical project, that Articles 111 to 114 needed a protocol, that other environmental conventions had their own dispute mechanisms, and that a permanent injunction could not be issued against a sovereign State. Those arguments raised serious issues. They failed in 2012 because they mixed jurisdiction with remedy and treated evidence-dependent objections as pure preliminary law. They failed in the later merits appeal in part because the challenge to the factual character of the project was raised too late, although the Appellate Division accepted that a live action under Article 30 must be sufficiently concrete.

The case therefore gives advocates a practical pleading lesson. An environmental claimant should identify the challenged State act, the Treaty duty engaged, the evidence showing environmental or transboundary risk, and the precise remedy sought. A State defending a project should raise ripeness, standing, jurisdiction, evidence and remedy as distinct questions, and should put its factual case on the record early. It should not assume that a national development policy or a feasibility study will answer a regional Treaty claim.

Dissent and later decisions

There is no dissenting judgment in Appeal No. 3 of 2011. The judgment was delivered by President Harold R. Nsekela with Justices of Appeal Emily R. Kayitesi and James Ogoola, and the operative order was unanimous. It would be inaccurate to invent a dissent or attribute a minority environmental theory to this case. The useful practical interpretation of the losing position comes from the Attorney General's submissions and from the later judgment's partial acceptance of the ripeness argument.

The later decisions make the precedent clearer. In Reference No. 9 of 2010, the First Instance Division declared the initial bitumen road proposal unlawful and issued a permanent injunction against implementing it in that form, while leaving room for programmes that would not negatively affect the Serengeti ecosystem. In Attorney General of the United Republic of Tanzania v African Network for Animal Welfare, Appeal No. 3 of 2014, the Appellate Division upheld the Treaty obligations, the Court's power to grant a permanent injunction and the environmental result, but accepted that Article 30 requires a concrete action rather than a bare idea. The combined lesson is careful rather than absolute: a court may prevent an imminent environmentally destructive plan, but it must still test whether the dispute is live and legally ripe.

This sequence also fits the Court's earlier reasoning in James Katabazi and its later treatment of hypothetical disputes in Legal Brains Trust v Attorney General of Uganda and Alcon International Ltd v Standard Chartered Bank of Uganda. Courts decide concrete Treaty controversies. At the same time, environmental remedies may be preventative because waiting for irreversible damage can make a final judgment useless. ANAW is valuable precisely because it holds those two ideas together.

The practical lesson for East Africa

For governments, the practical lesson is that infrastructure planning must contain a Treaty compliance file from the beginning. That file should explain the project design, environmental assessment, alternatives, biodiversity risk, cross-border implications, consultation record, financing and procurement decisions. It should show how national environmental law and the EAC Treaty were considered together. A project that is lawful only on paper, or only within one national ministry, is vulnerable when its effects move across borders.

For civil society organisations and affected communities, the case shows that regional litigation is not limited to completed construction. The challenge must still concern a live and sufficiently concrete act, but Article 30 can support an early intervention before irreversible harm occurs. The strongest case will connect public materials to a specific Treaty breach and ask for a remedy that matches the evidence. Broad accusations about development policy are less useful than a documented challenge to a defined decision, approval, procurement step or construction action.

The enduring value of Attorney General of Tanzania v ANAW is therefore institutional. It keeps environmental protection inside the law of regional integration. The EAC Treaty does not require Partner States to stop developing roads or other infrastructure. It requires them to develop in a way that respects sustainable use, cooperation, information, consultation and ecosystem protection. That is the balance the Court made enforceable, and it remains the central reason this case is useful to lawyers, public authorities and ordinary East Africans affected by major projects.
