I. Introduction

The enforceability of foreign arbitral awards lies at the heart of international commercial arbitration’s utility as a dispute resolution mechanism. An award that cannot be recognised and executed against assets is, for all practical purposes, worthless. For a jurisdiction seeking to position itself as a credible destination for foreign investment and cross border commerce, a robust and predictable enforcement regime is therefore not merely a technical legal requirement but a matter of economic policy.

Uganda has, over several decades, constructed a multi layered regime for the enforcement of foreign awards. That regime draws its normative force from three principal sources: (i) domestic legislation in the form of the Arbitration and Conciliation Act, Cap 4; (ii) Uganda’s adhesion to the 1958 New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards; and (iii) Uganda’s membership of and obligations under the ICSID Convention. Woven through these instruments is the influence of the UNCITRAL Model Law on International Commercial Arbitration, which shaped the structure of the ACA itself.

II. Overview of the Ugandan Arbitration Framework

A. The Arbitration and Conciliation Act, Cap 4

The primary domestic instrument governing arbitration in Uganda is the Arbitration and Conciliation Act, Cap 4 of the Laws of Uganda (hereinafter ‘the ACA’). The ACA is substantially modelled on the UNCITRAL Model Law on International Commercial Arbitration and provides a comprehensive framework covering arbitration agreements, the constitution and jurisdiction of arbitral tribunals, the conduct of proceedings, the making and correction of awards, and critically, the recognition and enforcement of both domestic and foreign awards.

The ACA is divided into several Parts. For present purposes, the most significant are: Part III which deals with the recognition and enforcement of foreign awards under the New York Convention; Part IV which governs the enforcement of awards rendered under the ICSID Convention; and Part V which contains miscellaneous provisions including the rule-making powers exercised by the court.

B. Institutional and Ad Hoc Arbitration in Uganda

Uganda has a functioning Centre for Arbitration and Dispute Resolution (CADER), established under the ACA and operating under the supervision of the Ministry of Justice and Constitutional Affairs. CADER is the principal government backed institution for the administration of both domestic and international arbitrations and conciliations in Uganda, and maintains a panel of accredited arbitrators and mediators drawn from across the legal, engineering, construction, and commercial sectors.

Beyond CADER, Uganda has a growing ecosystem of private and professional institutions that provide arbitration training, capacity building, and alternative dispute resolution services. These include the Institute of Chartered Arbitrators of Uganda (ICAMEK), which is affiliated to the Chartered Institute of Arbitrators (CIArb) and offers accredited training programmers leading to Fellowship and Membership of CIArb; the Uganda chapter of the Chartered Institute of Arbitrators (CIArb Uganda), which promotes professional standards in arbitration practice and links Ugandan practitioners to the global CIArb network; and the Muslim Arbitration and Mediation Centre, which provides faith based dispute resolution services in accordance with Islamic principles and serves communities for whom such processes are preferred. Other bodies active in the ADR landscape include bar associations, university-based dispute resolution clinics, and specialised commercial mediation providers. Collectively, these institutions have contributed to deepening the culture of arbitration and mediation in Uganda and to building a cadre of trained local arbitrators capable of handling both domestic and international disputes.

International parties are not confined to CADER or any of the domestic institutions. They may elect ad hoc arbitration under the UNCITRAL Arbitration Rules, the ICC Rules, the LCIA Rules, or any other procedural framework agreed between them. They may equally designate a foreign seat and conduct proceedings outside Uganda while still requiring enforcement of the resulting award within Uganda. Regardless of the procedural rules chosen or the institutional framework adopted, the ACA applies as the lex arbitri to arbitrations seated in Uganda and provides the overarching framework for the recognition and enforcement of foreign awards in Ugandan courts.

III. The New York Convention (1958) and Its Domestic Reception

A. Uganda’s Accession and Its Significance

Uganda acceded to the Convention on the Recognition and Enforcement of Foreign Arbitral Awards, done at New York on 10 June 1958 (the ‘New York Convention’ or ‘NYC’), on 12 February 1992. The NYC represents the single most important instrument in international arbitration. To date, it has over 170 contracting states. Its core obligation, found in Article III, requires each Contracting State to recognise arbitral awards as binding and to enforce them in accordance with its rules of procedure, subject only to the limited grounds of refusal set out in Article V.

Uganda’s accession was accompanied by the reciprocity reservation permitted under Article I (3) of the NYC, meaning that Uganda applies the Convention only to awards made in the territory of another Contracting State. In practical terms, this reciprocity reservation rarely poses a problem given the near-universal participation in the NYC.

B. Domestic Implementation: Part III of the ACA

Part III of the ACA (sections 35 to 44) gives domestic effect to the New York Convention. A ‘foreign award’ is an arbitral award on differences between persons arising out of legal relationships, whether contractual or not, considered as commercial under the law in force in Uganda, made in pursuance of an agreement for arbitration to which the NYC applies, and in the territory of a state that is a party to the NYC.

Section 36 provides that a foreign award like any other award shall be recognised as binding and shall, upon application in writing to the High Court, be enforced subject to the provisions of the ACA. The enforcement is thus treated as a matter of right subject only to specified defences a posture that aligns with Article III of the NYC.

Under section 37, the party seeking enforcement must produce (a) the duly authenticated original award or a duly certified copy; (b) the original arbitration agreement or a certified copy thereof; and (c) where the award or agreement is in a foreign language, a certified translation. These requirements mirror Article IV of the NYC.

C. Grounds for Refusal Under the NYC / Section 38 ACA

Section 38 of the ACA mirrors Article V of the NYC and provides an exhaustive list of grounds on which recognition or enforcement of a foreign award may be refused. These are discussed in greater detail in Part VII of this write up.

IV. The ICSID Convention and Part IV of the Arbitration and Conciliation Act

A. Uganda as a Member of ICSID

Uganda ratified the Convention on the Settlement of Investment Disputes between States and Nationals of Other States, opened for signature on 18 March 1965 (the ‘ICSID Convention’ or ‘Washington Convention’), and is therefore a member state of the International Centre for Settlement of Investment Disputes (ICSID). The ICSID Convention provides a self-contained procedural framework for the arbitration of investment disputes between states and foreign investors, administered by ICSID under the auspices of the World Bank Group.

The ICSID Convention’s enforcement regime is notably more automatic than that of the New York Convention. Under Article 54(1) of the ICSID Convention, each Contracting State is obliged to recognise an ICSID award as binding and to enforce the pecuniary obligations imposed by it as if it were a final judgment of a court in that State. Crucially, there is no equivalent of the Article V NYC defences available at the enforcement stage; challenges to ICSID awards must be pursued internally through the ICSID annulment procedure under Article 52.

B. Part IV of the ACA: Sections 45–47

Part IV of the ACA (sections 45, 46 and 47) transposes Uganda’s ICSID Convention obligations into domestic law. The scheme is straightforward but consequential.

1. Section 45  Definition of an ICSID Convention Award

Section 45(1) defines an ‘ICSID Convention award’ as an arbitral award rendered pursuant to the ICSID Convention. Section 45(2) extends this definition to include any decision interpreting, revising or annulling an award under the Convention, and any decision as to costs forming part of the award. The date of an award is fixed as the date on which certified copies are dispatched to the parties pursuant to the ICSID Convention — a provision that has significance for time-limitation purposes.

2. Section 46 Registration

Section 46 establishes a registration-based enforcement procedure. A party seeking to enforce an ICSID Convention award must apply to the High Court for registration of the award. The application is subject to proof of prescribed matters and to the other provisions of Part IV. Importantly:

• the award is registered not merely for the primary sums awarded but also for the reasonable costs of and incidental to registration (section 46(2));
• if the pecuniary obligations have been partly satisfied at the date of application, registration is confined to the balance; and if wholly satisfied, registration is refused (section 46(3)); and
• the rule making power under section 68 of the ACA extends to prescribing the procedure for registration applications, including requirements of prior notice to other parties and the furnishing of a copy of the award certified pursuant to the ICSID Convention (section 46(4)).

3. Section 47 Enforcement

Section 47 is the key operative provision. It provides that a registered ICSID Convention award shall, as respects its pecuniary obligations, have the same force and effect as a judgment of the High Court given when the award was rendered, entered on the date of registration. The consequences are significant:

• ordinary execution proceedings may be taken on the registered award;
• the registered sum carries interest as if it were a judgment debt; and
• the court exercises the same supervisory control over execution as it would over any of its own judgments.

Section 47(2) further provides that rules of court may require the court, on proof of prescribed matters, to stay execution of a registered ICSID award where enforcement has been stayed pursuant to the ICSID Convention itself acknowledging the primacy of the ICSID internal system in annulment and stay proceedings.

C. The Automaticity of ICSID Enforcement

The most important conceptual difference between enforcement under Part III (NYC) and Part IV (ICSID) of the ACA is the absence, in the latter, of any merits-based defence. Once an award has survived (or not been subjected to) the ICSID annulment procedure, the domestic court’s role in enforcement is purely ministerial: it registers the award and issues execution. The court cannot inquire into whether the ICSID tribunal had jurisdiction, whether the award is contrary to public policy, or whether there were procedural irregularities. This is expressly the effect of Article 54 of the ICSID Convention, faithfully implemented by section 47 of the ACA.

V. The UNCITRAL Model Law Dimension

Although Uganda has not enacted the UNCITRAL Model Law on International Commercial Arbitration (1985, as amended 2006) as a freestanding statute, the ACA is substantially based upon it. The Model Law’s provisions on the recognition and enforcement of awards particularly Articles 35 and 36 are closely reflected in the structure and language of Part III of the ACA.

Article 35 of the Model Law provides that an arbitral award, irrespective of the country in which it was made, shall be recognised as binding and shall be enforced on application in writing to the competent court. Article 36 enumerates the exclusive grounds for refusing recognition or enforcement, which closely track Article V of the NYC.

The Model Law’s influence is particularly apparent in the ACA’s provisions on judicial non intervention (mirroring Article 5 of the Model Law), the separability of the arbitration agreement, the competence competence principle, and the standards for setting aside domestic awards. Courts interpreting the ACA have, on occasion, referred to UNCITRAL Model Law commentaries and travaux préparatoires as aids to construction, making familiarity with the Model Law essential for practitioners in this field.

VI. Grounds for Refusal of Enforcement in Uganda

A. The Exhaustive Nature of the Defences

A defining feature of the NYC enforcement regime, replicated in section 38 of the ACA, is that the defences to enforcement are exhaustive. No ground outside section 38 may be invoked to refuse recognition or enforcement of a foreign award. This list based approach reflects a deliberate policy choice in favour of finality and the sanctity of party autonomy.

B. Party-Invocable Grounds (Section 38(1) / Article V(1) NYC)

The following defences may only be raised at the instance of the party resisting enforcement and must be proved by that party:

• Incapacity: A party to the arbitration agreement was under some incapacity, or the agreement is not valid under its governing law;
• Notice: The party against whom enforcement is sought was not given proper notice of the arbitral proceedings or was otherwise unable to present its case;
• Excess of jurisdiction: The award deals with differences not falling within or not contemplated by the submission to arbitration, or contains decisions on matters beyond the scope of the submission subject to the possibility of severing the out-of-scope portion;
• Composition irregularity: The composition of the arbitral authority or the arbitral procedure was not in accordance with the agreement of the parties or, failing such agreement, with the law of the country where the arbitration took place; and
• Non binding award: The award has not yet become binding on the parties, or has been set aside or suspended by a court of the country in which, or under the law of which, it was made.

C. Court-Raised Grounds (Section 38(2) / Article V(2) NYC)

In addition, the High Court may on its own motion refuse enforcement where:

(i)  Non arbitrability: The subject matter of the difference is not capable of settlement by arbitration under the law of Uganda; or

1. (ii) Public policy: Recognition or enforcement of the award would be contrary to the public policy of Uganda. As noted in Part VI, Ugandan courts have adopted a narrow construction of the public policy exception, in line with the internationally prevailing approach that the exception is reserved for the most fundamental violations of justice. In MSS XSABO POWER LTD & 4  others v GREAT LAKES ENERGY COMPANY NV Arbitration Causes No. 0075 of 2023 and 0014 of 2024 court noted that the concept of public policy cannot become a trap door to allow the control of the substantive decision adopted by the arbitrators and for that reason interpreted narrowly. an award could be set aside under the Act as being inconsistent with the public policy if it is shown that either it was: (a) inconsistent with the Constitution or other laws of Uganda, whether written or unwritten; or (b) is inimical to the national interest of Uganda (national defence and security, good diplomatic relations with friendly nations, and the economic prosperity of Uganda) or; (c) is contrary to justice and morality (including questions of whether the award was induced by corruption or fraud)

D. The ICSID Exception: No Article V Defences

For ICSID Convention awards, none of the above defences is available at the domestic enforcement stage. The enforcing court cannot refuse registration on any of the grounds available under section 38. The only mechanism for challenging an ICSID award is the Article 52 annulment procedure before an ICSID ad hoc committee. This distinction is crucial and frequently misunderstood in practice.

VII. Procedural Mechanics of Enforcement

A. Jurisdiction

Applications for enforcement of foreign awards under the ACA are made to the High Court of Uganda.

B. The Application Process

The enforcement process is summary in character. Under sections 36 and 37 of the ACA (for NYC awards), the applicant files an originating summons or chamber application supported by an affidavit exhibiting:

(a) the duly authenticated original award or certified copy;

(b) the original arbitration agreement or certified copy; and

(c) certified translations of any foreign-language documents.

For ICSID awards under Part IV, the procedure tracks section 46 and the rules made thereunder: the applicant furnishes a copy of the award certified pursuant to the ICSID Convention and gives prior notice of the intention to register to the other parties.

C. Notice and Opportunity to Oppose

While the enforcement of a foreign award is prima facie a matter of right, the procedural rules require that the respondent party be given notice and an opportunity to oppose. Opposition must be grounded in one of the statutory defences; a general challenge to the merits of the award is not permissible. Ugandan courts have consistently resisted attempts to use the enforcement stage as a vehicle for reopening the substantive dispute.

D. Stay of Enforcement

Section 38(3) of the ACA empowers the High Court, where an application to set aside or suspend the foreign award has been made in the country of origin, to adjourn the enforcement proceedings and may, on the application of the party claiming enforcement, order the other party to provide security. This mirrors Article VI of the NYC. In the ICSID context, section 47(2) permits a stay where enforcement has been stayed pursuant to the ICSID Convention that is, where an Article 52 application is pending before ICSID.
