Holding

The High Court held that the appeal was filed within time after overruling a preliminary objection. On the merits, the court found that the trial magistrate erred in determining res judicata on affidavit evidence where material facts were contested, including the identity of the suit land and the authenticity of purchase documents. The proper course was to defer the res judicata issue for trial. The appeal succeeded in part: the dismissal order was upheld but the finding on res judicata was set aside, leaving the issue open for trial. The matter was remitted for hearing by another magistrate.

Outcome

Matter remitted to Chief Magistrate's Court for hearing by another magistrate with res judicata issue left open for determination at 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 by virtue of 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 seeking dismissal on grounds of res judicata and non-disclosure of a cause of action. The trial magistrate dismissed the application, holding the suit was not res judicata because the respondent purchased in 2006 before the 2012 suit was instituted and was not a party to that suit. The appellants appealed.

Issues

  1. Whether the appeal was filed out of time.
  2. Whether the trial magistrate erred in ruling that the 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 where material facts are contested.

Orders

  • Dismissal order of the trial court and costs awarded are upheld.
  • Holding that the suit is not res judicata is set aside.
  • Res judicata issue left open to be canvassed again if made an issue for trial.
  • File remitted to 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 — 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 — Dismissal of Preliminary Objection
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) of the Civil Procedure Rules, and requires leave of the trial court to appeal where the dispute remains to be heard and determined.
Civil Procedure — Res Judicata — Determination on Affidavit Evidence — Contested Material Facts
Where material facts relevant to a plea of res judicata are contested on affidavit evidence, including the identity of the suit land and the relationship between parties in the earlier and subsequent suits, the trial court cannot fairly determine the plea on affidavit evidence alone. Res judicata is a mixed question of fact and law requiring a trial where evidence is lacking to dispose of the point.
Civil Procedure — Res Judicata — Reliance on Unproved Documents
A trial court errs when it relies on a document that has not been proved in evidence, such as a photocopy of a handwritten document in a local language, to determine a preliminary objection on grounds of res judicata. Such controversial matters require a trial and cannot fairly be resolved on affidavit evidence.
Civil Procedure — Res Judicata — Burden of Proof — Proper Practice
The burden of proving res judicata rests on the person raising the plea. Where res judicata is pleaded as a defence and the issue is contested, the proper practice is for the trial court to try that issue and receive evidence to establish that the subject matter of the dispute between the parties has been litigated upon between the same parties or parties through whom they claim.
