The practical lesson
The river, the lake and the legal dispute
Lake Victoria is shared by several East
African states, while the Nile flows out of the lake at Jinja in Uganda.
Decisions about how much water is released can affect livelihoods,
infrastructure, fisheries, shorelines and downstream users. That makes the
subject regional even when the control point sits within one country. Isaac E.
N. Okero and 4 Others v Attorney General of Uganda and Others concerned
allegations that Uganda’s management of water releases breached East African
Community (EAC) Treaty duties and regional water policies. The judgment is
important, but it must be read accurately: the Court did not decide whether
Uganda’s water releases caused flooding or whether a particular release policy
had been breached. It dismissed the reference as time-barred and moot.
This distinction should guide any use of
the case. The applicants raised questions about cooperation, shared resources
and institutional responsibility involving Uganda, the EAC Secretary General
and the Lake Victoria Basin Commission (LVBC). The Court’s decision is
therefore most useful as a procedural warning for future regional environmental
or water claims. Its practical message is that a claim may raise an urgent
public issue and still fail before the Court reaches that issue if the claimant
does not identify when the Treaty breach occurred, file within the Treaty
period and demonstrate a live dispute supported by evidence.
What the applicants alleged
Isaac E. N. Okero, Geoffrey Yogo, Raymond
Olendo, Jared Sala and Moses M. Omondi filed Reference No. 14 of 2020 on 22 May
2020 against Uganda’s Attorney General, the EAC Secretary General and the LVBC.
They alleged that Uganda had failed to follow an agreed policy governing
releases from Lake Victoria into the River Nile at Jinja. They said that rising
water levels after the short rains of 2020 caused flooding and damage to
lakeshore communities. They sought declarations and compensation, arguing that
failure to comply with a shared policy undermined cooperation and responsible
management of a regional resource.
The case involved a history of policies
that required careful legal treatment. Uganda argued that the 1954 Agreed Curve
Policy had become problematic and that a later EAC Water Release and
Abstraction Policy had only conditional approval for four years and expired in
2016. Uganda also contended that a new policy was under consideration, that the
matter was moot and that the claims were not supported by evidence tying the
alleged policy breach to the flooding. The Secretary General and LVBC denied
responsibility, arguing that they did not directly control the release of water
at Jinja and had been improperly joined.
The case was determined by the EACJ First
Instance Division, with Principal Judge Yohane B. Masara, Deputy Principal
Judge Richard Wabwire Wejuli, and Justices Richard Muhumuza, Leonard Gacuko and
Ignace Rene Kasanda. The judgment was delivered on 27 November 2025 and is
reported as [2025] EACJ 14. It was not a dissenting judgment; the Court issued
a collective decision.
The legal questions before the Court
The reference asked whether Uganda’s
alleged failure to follow water-release policies violated the EAC Treaty,
including principles of cooperation, good governance, rule of law and
protection of shared resources. It also raised whether the Secretary General
and LVBC had failed to perform duties assigned to them by the Treaty and the
regional institutional framework. Before reaching those substantive issues,
however, the Court had to decide whether the case was brought within the
two-month period in Article 30(2) and whether a live, justiciable dispute
remained when the judgment was delivered.
Article 30(2) of the EAC Treaty provides
that proceedings must be instituted within two months of the date when the
complainant became aware, or ought to have become aware, of the act,
regulation, directive, decision or action complained of. This is a strict
procedural rule that protects legal certainty and allows states and Community
institutions to know when a dispute has become final. In a case about an
ongoing environmental condition, the difficult task is to distinguish a
continuing consequence of an old act from a new Treaty violation that starts a
fresh limitation period.
The Court also had to address mootness. A
case is moot when there is no longer a live dispute for a court to resolve, for
example because the challenged policy has expired or the requested ruling would
not change the parties’ legal position. Environmental effects can continue long
after a policy lapses, but continued harm does not automatically keep a legal
claim alive. A claimant has to explain what current act or omission is still
unlawful, which legal obligation remains in force and what practical order the
court can make.
Why the Court did not decide the water merits
The Court concluded that it lacked
jurisdiction to determine the reference on its merits because the applicants
had not shown that the proceedings were filed within Article 30(2)’s two-month
limit. The judgment found that the dates identified as the cause of action were
not adequately supported and that the applicants had not pinpointed when either
of the alleged policies was violated. The Court was not satisfied that the
filing was timely. It therefore dismissed the reference in its entirety as
time-barred and moot.
Mootness followed from the policy history
and the evidentiary record. The later Water Release and Abstraction Policy had
expired in 2016, before the 2020 filing. The Court accepted that it was no
longer operational when the reference was filed. The case therefore could not
simply ask the Court to enforce an expired policy without identifying a current
legal duty, a live breach and an effective remedy. The Court also considered
the weakness in the evidence linking the alleged policy violations to the floods
and loss claimed by the applicants.
This outcome does not amount to a finding
that Uganda complied with every water-management duty, that flooding did not
occur, or that the applicants’ communities suffered no harm. Those substantive
issues were not resolved. Nor did the Court decide the full extent of LVBC’s or
the Secretary General’s institutional responsibilities. Lawyers and public
commentators should not describe the result as an endorsement of Uganda’s
water-release decisions. The holding is procedural: the Court could not reach
the merits because the claim was late and moot on the record presented.
Article 30 and the two-month filing period
The governing principle is that a Treaty
reference must be filed within two months after the complainant knew or should
have known of the challenged act or omission. A claimant cannot avoid the
limitation period simply by describing an old decision as a continuing breach.
The claimant should identify the particular decision, action or omission, the
date it occurred or became known, and the reason the case was filed within two
months. Where several actions are challenged, each may require its own chronology.
In natural-resource disputes, the rule
requires especially disciplined fact gathering. Flooding, pollution or altered
water flow may develop over time. A legal team should distinguish the date when
the environmental condition began, the date when a state made a relevant
decision, the date when an authority failed to act despite a duty to do so, and
the date when the claimant obtained reliable knowledge of the alleged breach.
Those are not interchangeable dates. The limitation period turns on the Treaty cause
of action, not on the date a person later chooses to describe the problem as a
legal dispute.
The Court’s approach also signals that
proof of harm and proof of a Treaty breach are separate. A person may prove
that flooding occurred, but still need to show which government or regional
body breached which legal duty and how that breach caused or contributed to the
damage. Conversely, proof that an old policy existed does not establish that it
remained legally operative or that a later decision violated it. Good evidence
connects the policy, the act or omission, the knowledge date, the environmental
change and the remedy sought.
The principle for shared-resource disputes
The case does not establish a substantive
rule that a state may manage a transboundary resource without regard to its
neighbours. The Treaty contains cooperation and good-governance obligations,
and shared-water instruments can create additional duties. The narrower rule
from Okero is that those obligations must be brought before the EACJ through a
timely, properly evidenced claim that identifies an operative legal duty and a
live controversy. Regional importance does not excuse the claimant from the Court’s
jurisdictional requirements.
This procedural principle is especially
important because shared resources create complex causal questions. Water
levels respond to rainfall, catchment conditions, infrastructure, withdrawals,
climate variability and downstream management. To show that an alleged policy
breach caused flooding, claimants may need hydrological records, official
release data, expert evidence, dated photographs, loss records and witness
accounts. They should connect those facts to the exact wording and duration of
the policy relied on. An allegation that water was “released too quickly” or
“not controlled” is not enough without a legal and scientific chain the Court
can test.
The 1999 EAC Treaty provides the
institutional foundation for regional cooperation. Article 5(1) identifies the
objectives of the Community, while Article 6(d) includes good governance and
rule-of-law principles. Articles 112 to 114 deal with cooperation in the
environment and natural resources, including coordinated action. The Nile River
Basin Cooperative Framework Agreement and the LVBC’s protocols and policies may
also matter, depending on ratification, applicability and the precise claim.
The claimant must show how each instrument applies; citing a list of provisions
without connecting them to facts does not make a Treaty cause of action.
Why the judgment still matters
For residents exposed to flooding or
shoreline erosion, the decision is sobering because it shows how procedural law
can determine whether a court ever examines substantive harm. A claim may
concern a basic livelihood and a shared ecosystem, but urgency does not itself
suspend a filing deadline. Community organisations need legal support early,
before technical reports are lost, policy documents expire or the critical
decision date becomes contested.
For public institutions, the judgment
highlights the value of clear and current policies. If an agreed policy
expires, agencies should say what replaces it, how the new framework was
adopted and which institution is responsible for implementation. Gaps between
an expired policy and a successor can generate uncertainty, weaken
accountability and leave affected communities unsure where to direct
complaints. Documented decision-making also makes it easier for governments to
show how they balanced regional obligations and local needs.
For the EAC, the case illustrates a
recurring governance problem: regional policy can be formally agreed but hard
to enforce when domestic agencies control the actual infrastructure. A regional
institution may coordinate, monitor or set standards while a Partner State
operates the water outlet. The legal question is whether a Treaty or instrument
gives the regional body an enforceable duty that it failed to perform, not
simply whether its participation would have been helpful. The EACJ’s refusal to
decide the case on the merits does not settle that institutional question for
future disputes.
The judgment is a reminder that a strong
environmental or resource claim needs both a legal theory and a litigation
plan. The legal theory identifies which obligations bind each respondent. The
litigation plan records when the cause of action arose, preserves evidence,
explains why the issue remains live and seeks an order that can be implemented.
Without those elements, the court may never reach the underlying policy
question.
What the parties’ advocacy teaches
The applicants identified a serious
regional concern and relied on the Treaty’s cooperation and environmental
provisions. They sought to show that Uganda had failed to follow policy on
water releases, causing widespread harm. Their challenge illustrates why a
group claim needs a detailed chronology from the outset. The application should
have identified the policy provisions relied on, the specific release decisions
or failures to act, the date each occurred, when the applicants learned of them
and how the filing fell within Article 30(2).
The respondents focused on threshold
questions that were decisive: the policies had expired; the applicants had not
established when a breach occurred; the filing was outside the two-month
period; and the evidentiary link between water release and flooding was
inadequate. Uganda also disputed that the old 1954 Agreed Curve remained
controlling, while the Secretary General and LVBC challenged their joinder
based on their roles. These arguments show that a respondent can defeat a
potentially important public-law dispute without persuading the Court on the
merits of water management.
It would be unfair to say that the
applicants lost because their lawyers failed to make a single argument. The
judgment is clearer about the defects in proof and timing than it is about
counsel’s subjective choices. The practical improvement for future advocates is
to front-load evidence and jurisdiction. Use a timeline, attach the operative
policy and its adoption or expiry instruments, seek official release records,
commission hydrological analysis where causation matters, and explain each
respondent’s precise legal duty. If the complaint is continuing, identify fresh
acts or omissions with dates rather than relying on a broad continuing-breach
label.
The respondents’ success on timing and
mootness also carries a responsibility for institutions. A time-bar ruling does
not erase public accountability. Where a policy has expired, the relevant state
and regional bodies should make current duties transparent and accessible.
Communities should be able to identify the responsible authority, the complaint
channel, the review period and the available remedy without having to infer
them from old agreements.
Earlier and later regional law
Okero fits within the EACJ’s strict
application of Article 30(2). In Attorney General of the United Republic of
Tanzania v Anthony Calist Komu, Appeal No. 2 of 2015, the Appellate Division
treated the two-month period as a jurisdictional requirement. In Attorney
General of the Republic of Uganda v Omar Awadh and Others, Appeal No. 2 of
2014, the Court also addressed how knowledge and the challenged act affect the
period. These authorities make it risky to wait until environmental damage has
accumulated before seeking legal advice.
The case is also distinguishable from
disputes where a court finds continuing violations or concealment that affects
the knowledge date. A continuing environmental consequence is not necessarily
the same thing as a continuing Treaty violation. If an authority makes a fresh
water-release decision each month, or repeatedly refuses a current legal
obligation, those acts may present distinct causes of action, but a litigant
must identify and prove them. Okero cautions against assuming that one
long-running physical condition automatically renews the limitation period.
National environmental remedies remain
relevant. Uganda’s Constitution recognises duties relating to environmental
protection and the right to a clean and healthy environment, and the National
Environment Act, 2019 provides a domestic framework for environmental
management and remedies. Uganda’s Water Act and subsidiary regulations govern
aspects of water resources. National courts and regulators may be better
positioned to determine immediate evidence, compensation and administrative
questions. Those national proceedings do not remove the need to meet the EACJ
filing limit for a separate Treaty claim, but they can preserve evidence and
provide remedies closer to the affected communities.
There was no separate dissenting judgment
in Reference No. 14 of 2020. The panel’s unanimous procedural disposition is
the decision. It should not be treated as a split on the substantive
environmental duties, because the Court did not reach those duties.
Practical steps for future claimants
A community or organisation considering a
regional water claim should first create a dated event record. The record
should include the first time the community observed the harm, the date of each
relevant water-release decision, dates of complaints to national agencies, the
response or absence of response, and the date when reliable evidence of the
alleged Treaty breach became available. It should distinguish observation from
inference. A photograph of a flooded home proves a condition at a time and place;
it does not on its own prove which policy was breached or who caused the flood.
Next, identify the legal instrument and its
status. Obtain the full text of any regional policy, implementation decision,
protocol or agreement, including approval dates, conditions, amendments and
expiry terms. Confirm whether Uganda and the relevant EAC bodies were legally
bound by it at the time in question. Identify which official had authority to
release or regulate water, which body monitored compliance and what role the
LVBC or Secretary General had under the instrument. The pleadings should not treat
all respondents as interchangeable.
Finally, act within the shortest plausible
limitation period. If a potentially actionable decision becomes known, seek
advice immediately and file protectively where necessary while evidence is
developed. Explain the specific legal action being challenged and the knowledge
date. Request relief that addresses a present legal issue, such as a
declaration about a current duty or an order requiring transparent compliance
with an operative framework. If compensation is sought, document loss and
provide a credible account of causation.
The practical lesson
The Okero case is important because it
shows both the promise and the limits of regional resource litigation. The EAC
Treaty can provide a legal framework for disputes about shared water and
institutional cooperation. Yet the Court will not decide those matters in the
abstract or excuse a late reference because the subject is important. A
claimant must bring a live dispute, identify current duties, file on time and
prove the factual link between the alleged breach and the harm.
For communities, the lesson is to seek
legal and technical help early and keep evidence from the first sign of harm.
For governments and regional institutions, it is to maintain clear, current
water rules and communicate who is responsible for implementing them. For
advocates, it is to plead chronology and causation as carefully as the
environmental principle. In this reference, the Court left the substantive
merits open. Future cases can still test the duties of Uganda, the Secretary
General and the LVBC, but they will need to arrive with a timely claim and a
record capable of supporting the decision requested.
