The appointment dispute and the Treaty question

A court appointment is not only a personnel decision. It tests whether constitutional offices are filled through the institutions and procedures that the law assigns to them. That is why the challenge in Male H. Mabirizi K. Kiwanuka v Attorney General of the Republic of Uganda reached beyond the careers of two judges. It asked whether presidential nomination, parliamentary approval and the advice of the Judicial Service Commission had been arranged in a way consistent with the East African Community’s commitments to the rule of law and good governance. The East African Court of Justice (EACJ) had to decide whether the asserted defects were proved and, if proved, whether they amounted to a breach of the Treaty rather than only a disagreement about domestic constitutional procedure.

The complete citation is Male H. Mabirizi K. Kiwanuka v Attorney General of the Republic of Uganda, Reference No. 29 of 2020, [2026] EACJ 6 (31 March 2026) (First Instance Division). The Court sat as a five-judge panel: Principal Judge Yohane Bokobora Masara, Deputy Principal Judge Richard Wejuli, Richard Muhumuza, Gacuko Leonard and Kayembe Ignace Rene Kasanda. The published record identifies a judgment of the Court and does not identify a separate dissenting opinion. The EACJ’s official case listing gives 31 March 2026 as the delivery date, although the earlier case page had listed a hearing or delivery date of 30 March. The neutral citation and final judgment date should be used when citing the decision.

Mabirizi filed the reference on 8 September 2020 against Uganda’s Attorney General. He challenged the appointment of Justice Alphonse Chigamoy Owiny-Dollo as Chief Justice and Justice Richard Buteera as Deputy Chief Justice. The allegations concerning the deputy chief justice included that the position had not been advertised or independently declared vacant, that Buteera had applied for the Chief Justice position but not the deputy position, and that the Judicial Service Commission (JSC) had not separately recommended him. Mabirizi also said Parliament failed to respond to his petitions, conducted vetting in camera, and did not put the Appointments Committee report before the plenary for debate and vote. These were allegations to be tested against the record, not findings that could be assumed from the fact that a challenge was filed.

The legal issue was whether the nomination, vetting, approval, appointment and swearing-in process violated Articles 6(d) and 7(2) of the Treaty for the Establishment of the East African Community, which require good governance and adherence to the rule of law, accountability and transparency. The case also involved the Court’s jurisdiction under Articles 23(1), 27(1) and 30(1), and the relationship between regional Treaty supervision and the constitutional allocation of appointment powers in Uganda. The applicant sought declarations of illegality, annulment of both appointments, a permanent injunction, damages and costs. The central question was therefore not whether the EACJ could simply choose Uganda’s judicial officers, but whether the alleged constitutional departures were established and were sufficiently serious to engage the Treaty.

What the Court actually decided

The EACJ dismissed the reference. The judgment record and its legal headnotes state that the Court found the appointment process lawful and that Mabirizi did not meet the evidentiary burden for the allegations advanced. It did not annul either appointment or award the requested injunction or damages. The outcome matters because constitutional language about transparency and rule of law did not, by itself, prove that the process was unlawful. The applicant had to substantiate the alleged procedural facts with credible and admissible material, then show how those facts engaged the Treaty obligations. A broad appeal to constitutional values could not substitute for proof of the specific defects pleaded.

Uganda’s response was evidence-centred. It relied on affidavits from the Clerk to Parliament and the Registrar of the JSC, along with written submissions. The State’s case was that the JSC had declared and advertised the Chief Justice vacancy, shortlisted three candidates, interviewed and ranked them, and advised the President on the Chief Justice appointment. It argued that the Deputy Chief Justice vacancy arose when Owiny-Dollo became Chief Justice and that the same competitive process had already considered and ranked Buteera. The dispute thus required the Court to evaluate the documented administrative chain, not merely compare the final appointments with the applicant’s account. That response supplied an evidential record explaining how the State understood the legal transition from one vacancy to the next.

The Court’s ruling should be stated with care. A dismissal is not a declaration that every appointment practice in Uganda is immune from scrutiny, nor does it mean that the EACJ declined all power to consider governance complaints. It means this challenge failed on its pleaded facts and evidence. The judgment’s value lies partly in the distinction between an arguable concern and a proved Treaty violation. Where a party alleges that a constitutionally required recommendation, approval, vacancy notice or parliamentary step was omitted, the court needs evidence about what the relevant body did, what instrument governed it, and why the omission mattered to legality or fairness.

The evidence behind a governance claim

A rule-of-law case is strongest when it follows a clear evidentiary sequence. First, the claimant identifies the precise constitutional or statutory step that was mandatory. Second, the claimant proves the relevant appointment timeline and the action or omission said to breach that step. Third, the claimant connects that domestic defect to a Treaty obligation within the EACJ’s jurisdiction. Fourth, the remedy is tailored to the proven breach. In Mabirizi, the assertions about vacancy, separate JSC advice, committee secrecy and parliamentary treatment were serious, but the Court found the evidence insufficient to establish a breach. A pleading that describes suspicion in detail can still fail if the supporting documents do not prove each link in the sequence.

This is a useful lesson in how lawyers should present governance litigation. A petitioner should obtain the vacancy notices, advertisement, shortlist, JSC minutes or recommendation, presidential instrument, parliamentary committee record, rules governing confidentiality, plenary record and any response to a petition. If those documents are held by public bodies, the claim should identify them precisely and explain what evidentiary step is requested if access is refused. Sworn testimony should distinguish personal knowledge from information received. Dates must align across the pleadings and exhibits. A court asked to infer unlawful conduct from missing paperwork will want to know whether the record is genuinely absent, merely inaccessible, or not legally required in the form the applicant expects.

Mabirizi’s own advocacy also illustrates a strategic distinction. The claimant framed the complaint through the Treaty’s rule-of-law and good-governance principles, which is the correct regional lens for alleged state action. The State responded with evidence of the JSC process, constitutional powers and a prior domestic decision on the same appointment. The lesson is not that self-represented or public-interest litigants cannot succeed. It is that litigation strategy must turn general constitutional objections into focused propositions that can be admitted or denied, supported by records, and answered under the precise text of the governing rules. A court cannot remedy a procedural defect simply because the subject is institutionally important.

The national constitutional framework

The domestic provisions at the centre of the dispute were Articles 142(1) and 147(1)(a) of the Constitution of Uganda. Article 142(1) provides for appointment of the Chief Justice, Deputy Chief Justice and other superior court judicial officers by the President acting on the advice of the JSC and with parliamentary approval. Article 147(1)(a) gives the JSC a role in advising the President on appointments to judicial office. Article 143 sets qualifications for the Chief Justice and Deputy Chief Justice. The appointment question therefore involved several institutions and legal steps; it was not a free-standing presidential choice. The judgment’s focus on the record of advice and vetting demonstrates why the operative constitutional text and the administrative documents must be read together.

The JSC Regulations, including Regulation 16 as discussed in the respondent’s case, governed the advertised Chief Justice process. The applicant’s account and the Government’s account diverged on how that process related to the later Deputy Chief Justice appointment. The legal significance of a consequential vacancy depends on the text and sequence: did the JSC advise on candidates for both offices, did the Constitution require a new and separate recommendation after the second office became vacant, and did Parliament approve the individual in the capacity required? A lawyer should not use the label ‘consequential appointment’ as a conclusion. It must be demonstrated from the constitutional provisions, the actual JSC record and the appointment instruments. The EACJ dismissed the challenge on the record before it, without turning the label into a general exemption from constitutional process.

The Ugandan Constitution also protects judicial independence in Article 128 and assigns functions to the JSC in Article 147. These protections matter in both directions. They require appointment processes to follow legal safeguards, but they also require courts to avoid converting a Treaty reference into a political contest over whether a particular judge is personally desirable. The rule of law includes legality of appointment and institutional independence after appointment. A sound challenge therefore focuses on process and legal authority rather than the appointee’s identity, reputation or the claimant’s disagreement with judicial outcomes.

Regional authority and the limits of review

Articles 6(d) and 7(2) of the EAC Treaty make the rule of law and good governance regional commitments. The EACJ has previously treated Treaty principles as enforceable obligations. In James Katabazi and 21 Others v Secretary General of the East African Community and Attorney General of Uganda, Reference No. 1 of 2007, the Court made clear that national constitutional processes cannot be used to place state conduct beyond Treaty scrutiny where the complaint falls within the Court’s mandate. In Samuel Mukira Mohochi v Attorney General of Uganda, Reference No. 5 of 2011, the Court likewise applied Treaty principles to state conduct affecting a regional citizen. Those authorities support the proposition that governance is justiciable at the EACJ; Mabirizi shows that a litigant must still prove a concrete breach.

The distinction is important. Article 27(1) gives the EACJ jurisdiction to interpret and apply the Treaty, while the Court is not a general appellate forum for every domestic constitutional question. A claimant must show a Treaty issue, not merely ask the EACJ to substitute its view for Uganda’s courts or parliamentary institutions. This is consistent with the line of authority reflected in Attorney General of the United Republic of Tanzania v African Network for Animal Welfare, Appeal No. 3 of 2011, and later Treaty-reference decisions: the Court safeguards Treaty compliance while respecting the division of jurisdiction established by the Treaty. The case’s persuasive value for constitutional-governance analysis is therefore procedural and institutional, rather than a broad ruling that the EACJ supervises all national appointments.

The EACJ’s earlier and related decisions concerning Mabirizi also show why each reference must be analyzed on its own pleaded act and time period. Other proceedings raised distinct issues about Parliament, judicial administration legislation and later institutional decisions. They cannot be combined into a single merits holding. Article 30(2) separately requires a reference to be brought within two months of the impugned enactment, publication, directive, decision or action, or its knowledge. A lawyer who frames a continuing governance complaint must identify the specific operative act and explain the timing; repeating a broad Treaty label does not reset the statutory filing period. Mabirizi’s Reference No. 29 of 2020 was decided on the appointment record pleaded in that proceeding.

What the case means for litigants

For a person challenging a judicial appointment, the practical lesson is to build the record before making the allegation. A petition to Parliament may show that a concern was raised, but it does not prove that the legal appointment steps were omitted. A closed committee hearing may be troubling, but the claimant must identify the rule governing openness, any exception for appointments, and the evidence that the rule was not followed. The absence of a public plenary debate is not automatically unlawful if the governing parliamentary procedure assigns the committee a particular role. Conversely, where a constitutional provision requires advice or approval, a court should be given the official record that permits it to decide whether that step occurred.

For the Attorney General and public institutions, the case points to a parallel lesson: preserve a defensible record. An appointment file should show the vacancy, advertisement if required, selection procedure, JSC recommendation, presidential action, parliamentary approval and the legal authority for any confidentiality. A clear file reduces the risk that lawful procedures will be obscured by fragmented records or inconsistent explanations. When challenged, the State should answer each pleaded allegation, rather than rely only on institutional deference. The respondent’s evidentiary case in Mabirizi was significant because it offered a traceable explanation for the decisions and their sequence.

For national first-instance courts, the decision can be persuasive when they confront claims that an ordinary administrative irregularity amounts to a regional rule-of-law breach. It supports careful examination of proof and a disciplined distinction between domestic-law error and Treaty violation. It does not require national courts to apply the EACJ’s factual conclusions as if they were binding in every appointment dispute. The EACJ is the regional court, and its judgment binds the parties in that reference; other courts may find its reasoning persuasive, especially where the same Treaty provisions and institutional duties arise. Lawyers should describe its status accurately instead of calling it binding precedent across national jurisdictions.

The case’s place in later decisions

As at 15 October 2026, no later appellate judgment reversing or varying this First Instance Division decision appears in the EACJ’s official case listing. The Court’s own listing records the March 2026 judgment, and the available published case report identifies the panel and dismissal. The decision may therefore be cited as a recent First Instance authority, subject to the hierarchy of the EACJ and any later appellate development. It should not be described as settling the legal constitutionality of all future judicial appointment procedures. Its reach is narrower: a Treaty challenge based on the facts and record in this case failed.

The strongest way to read the judgment alongside Katabazi and Mohochi is that access to Treaty review and success on the merits are separate matters. Those earlier authorities explain why Treaty principles may reach national conduct. Mabirizi shows that the court will not infer a Treaty breach from the importance of the office or the seriousness of the allegation. In practical terms, regional constitutional governance is not a shortcut around domestic procedure; it is a legal standard that must be invoked with evidence, within time, and through a remedy that matches the harm. That interpretation is more useful than treating either the dismissal or the constitutional language as an absolute rule.

The practical rule for future cases

The decision’s rule can be stated simply: a party alleging that a national judicial appointment breached the EAC Treaty must prove the specific constitutional or procedural defect with reliable evidence and show why it amounts to a breach of the regional commitments in Articles 6(d) and 7(2); broad assertions of secrecy, unfairness or illegality do not suffice. The EACJ can scrutinize national conduct when a genuine Treaty question is presented, but the Treaty does not make it a general appeal court over domestic appointments. The evidence must connect the national process to the regional obligation.

For advocates, this means turning the appointment file into a legal chronology: identify the office, vacancy, recommendation, vetting, approval and appointment date; state the mandatory instrument at each step; attach or properly seek the official record; and plead the Treaty consequence in a separate, reasoned step. For citizens, the decision shows that public accountability litigation is possible but that courts decide claims on proof rather than suspicion. For public institutions, it confirms that transparent records are not merely administrative housekeeping. They are the evidence by which lawful governance can be demonstrated.

Mabirizi is useful constitutional-governance authority precisely because it provides a disciplined limit. It recognises that domestic processes may raise regional questions, while refusing to treat any alleged procedural defect as a Treaty breach without proof. Its practical value for a first-instance court is not an abstract endorsement of executive or parliamentary discretion. It is a reminder to ask what the law required, what the record proves, and whether the proven conduct crosses the Treaty threshold. That is the approach that protects both meaningful accountability and the integrity of judicial appointment systems.

This case analysis is general legal information for research and public education. It does not determine the legality of a later appointment or replace advice on filing deadlines, evidentiary rules or remedies in a particular case. The reference was dismissed, and this analysis treats its holding as limited to the record and issues before the Court.
