Holding

On appeal from an Assistant Registrar's refusal of joinder, the Court held that res judicata was not established: the earlier ruling merely referred the tax question to the Tax Appeals Tribunal and directed payment of the garnished sum to URA, and the subsequent High Court appeal ended in a confidential consent judgment, so the execution question was never directly and substantially determined. On the merits, because the appellant had remitted USD 83,169.89 to URA as withholding tax and the decree holder sought the same sum in execution, URA's presence was necessary under Order 1 rule 10(2) of the Civil Procedure Rules to settle all questions arising from the remittance, avoid multiplicity of proceedings and bind affected parties. Appeal allowed and URA joined.

Outcome

Appeal allowed; Registrar's ruling set aside and Uganda Revenue Authority joined as 2nd respondent, with a timetable for hearing Miscellaneous Application No. 1221 of 2023

Facts

Judgment in HCCS No. 305 of 2014 awarded the 1st respondent and represented parties USD 155,247 plus 8% interest per annum from 16 October 2008. The parties computed the sum due at USD 277,373.52. Acting on advice from Uganda Revenue Authority that the share-sale proceeds were taxable, the appellant deducted USD 83,169.89 as withholding tax, remitted it to URA and paid the balance of USD 194,203 to the 1st respondent and other former employees. In Miscellaneous Application No. 2942 of 2018 the Court referred the question of taxability to the Tax Appeals Tribunal and, on counsel's consensus, directed that the garnished sum be paid to URA. The Tribunal dismissed the 1st respondent's application in 2022; his appeal to the Commercial Division was resolved by a consent judgment whose terms were confidential. The 1st respondent then sought, in execution proceedings, to recover the same USD 83,169.89 from the appellant. The appellant applied to join URA to Miscellaneous Application No. 1221 of 2023; the Assistant Registrar refused, holding URA was a stranger to the suit and execution. The appellant appealed.

Issues

  1. Whether the appeal was barred by the doctrine of res judicata by reason of the earlier ruling in Miscellaneous Application No. 2942 of 2018 and the subsequent tax proceedings.
  2. Whether Uganda Revenue Authority ought to be added as a 2nd respondent to Miscellaneous Application No. 1221 of 2023 on the ground that its presence was necessary for the effectual and complete determination of the execution dispute.

Rules and key headnotes

Civil Procedure — Res Judicata — Requirement that the Matter Be Directly and Substantially Determined
A plea of res judicata under section 7 of the Civil Procedure Act fails where the earlier ruling merely referred an issue to another forum or gave directions by consent, since the matter in issue was not heard and finally determined by a competent court.
Civil Procedure — Res Judicata — Effect of Confidential Consent Judgment in Prior Proceedings
Where a prior appeal concerning the same sum was disposed of by a consent judgment whose terms are confidential and undisclosed to the court, the court cannot find that the issue was conclusively resolved so as to bar subsequent litigation.
Civil Procedure — Joinder of Parties — Order 1 rule 10(2) — Necessary Party Test
A person may be added as a party under Order 1 rule 10(2) of the Civil Procedure Rules although no cause of action lies against them, where the orders sought would legally affect that person's interests or where their presence is necessary to enable the court effectually and completely to adjudicate upon and settle all questions involved in the matter.
Civil Procedure — Execution — Joinder of a Third Party Who Received Part of the Decretal Sum
A tax authority to which a judgment debtor remitted part of the decretal sum as withholding tax is a necessary party to execution proceedings in which the decree holder claims the same sum, because its joinder enables the court to determine whether the remittance discharged the decree, avoids multiplicity of proceedings and ensures any order binds all affected parties.
Civil Procedure — Appeal from Decision of Registrar — Duty of First Appellate Court to Re-evaluate the Record
On appeal from a decision of a registrar, the judge sits as a first appellate court and must re-evaluate the record and the applicable principles before reaching an independent conclusion on whether the registrar's discretion was properly exercised.
