Holding

The High Court held that the appeal was filed within time and overruled the preliminary objection. The court found that the trial magistrate erred in determining the question of res judicata on affidavit evidence, particularly by relying on an unproven document in Luo language. However, the court also held that the magistrate was correct to dismiss the preliminary objection, as res judicata is a mixed question of fact and law requiring a trial where evidence is contested. The appeal succeeded in part: the dismissal order was upheld, but the finding on res judicata was set aside to allow the issue to be tried alongside other issues in the main suit.

Outcome

Matter remitted to Chief Magistrate's Court for hearing by another Magistrate with the question of res judicata left open for trial

Facts

The respondent sued the appellants claiming ownership of 80 metres by 200 metres of land in Widwol Village, Agago District, which she allegedly purchased from Obonyo Akwilino Justine in 2006. She relied on a photocopy of a handwritten document in Luo. The appellants defended, asserting they lawfully owned the land pursuant to a 2013 judgment (civil suit Kit-02-064 of 2012) against Obonyo, and that the portion the respondent claimed was part of the land decreed to them. They contended the respondent was a squatter and the sale agreement was fabricated. The appellants filed a preliminary objection under Order 6 rules 28 and 30 CPR, arguing the suit was res judicata and disclosed no cause of action. The trial magistrate dismissed the application, holding the respondent could not be said to claim under Obonyo and the subject matter was different. The appellants appealed.

Issues

  1. Whether the appeal was filed out of time and is therefore incompetent.
  2. Whether the trial magistrate erred in ruling that the head suit was not res judicata.
  3. Whether the trial magistrate erred in relying on purchase documents whose authenticity was yet to be proved.
  4. Whether res judicata can be determined on affidavit evidence or requires a full trial.

Orders

  • Appeal succeeds in part but substantially fails.
  • Dismissal order of the trial court and costs awarded are upheld.
  • Holding that the suit is not res judicata is set aside, leaving the point open for trial.
  • File remitted to the trial court for hearing by another Magistrate.
  • Appellants to pay respondent half of the costs in this appeal.

Rules and key headnotes

Civil Procedure — Appeals — Time Limits — Computation of Time — Notice of Appeal Filed in High Court Instead of Request for Record in Trial Court
Where an appellant files a notice of appeal in the High Court instead of requesting the certified record from the trial court within the 30-day appeal period, but also files a copy in the trial court albeit later, the court may treat the notice as constituting a request for the record in the interest of substantive justice, and the appeal may be deemed filed within time if the memorandum is filed after certification of the record.
Civil Procedure — Appeals — Appealable Orders — Preliminary Objections — Dismissal of Preliminary Objection Under Order 6 Rule 30
An order dismissing a preliminary objection under Order 6 rules 28 and 30 of the Civil Procedure Rules does not fall within the category of orders appealable as of right under section 76(1) of the Civil Procedure Act or Order 44 rule 1(1) CPR, and requires leave of the trial court to appeal, as it does not conclusively determine the rights of the parties in the head suit.
Civil Procedure — Res Judicata — Determination on Affidavit Evidence — Mixed Question of Fact and Law
Res judicata is a mixed question of fact and law that requires a trial where the issue is contested and evidence is lacking to dispose of the point. A trial court should not determine res judicata on affidavit evidence alone, particularly where the parties dispute whether the suit land is the same as that litigated in an earlier suit, and should defer the issue for consideration alongside other issues at trial.
Civil Procedure — Res Judicata — Burden of Proof — Pleading and Proof
The burden of proving res judicata rests on the person raising the plea, who must place before the court all material particulars sufficient to give a finding whether the particular case is barred by res judicata. Where res judicata is pleaded as a defence and the issue is contested, the trial court should try that issue and receive evidence to establish that the subject matter has been litigated upon between the same parties or parties through whom they claim.
Evidence — Documentary Evidence — Reliance on Unproven Documents — Determination of Preliminary Objections
A trial court errs when it relies on a document that has not been proved in evidence, particularly a photocopy of a handwritten document in a local language, to determine a preliminary objection on res judicata. Such controversial matters require a trial and cannot fairly be resolved on affidavit evidence.
