The bottom line
#Kenya's Court of Appeal refused to accept new evidence in a land dispute, confirming appeals must run on the record built at trial.
What this practically means
#Executive summary
#Key legal issues
#Whether the proposed additional evidence met the threshold in Rule 31(1)(b) and the Mahamud v Mohamad principles
The application failed because the evidence was within the parties' knowledge and obtainable with reasonable diligence, similar issues were already raised and rejected in review proceedings, and the appeal could be determined on the existing record.
The Court applied the Supreme Court's principles in Mahamud v Mohamad requiring that additional evidence be relevant, credible, not obtainable with reasonable diligence at trial, and not aimed at filling gaps. Here the issues of the consent's validity and counsel's authority were central to the trial court proceedings; the applicant failed to call key witnesses when given the opportunity; substantially the same allegations were raised and rejected in the review application, against which no appeal was lodged; and the existing record sufficed to determine the appeal.
Whether the application was an attempt to patch up weak points in the applicant's case
Yes; the Court held the proposed evidence was aimed at bolstering the applicant's case on appeal rather than being necessary for the determination of the appeal.
Guided by the Supreme Court in Mahamud v Mohamad, the Court reiterated that additional evidence cannot be used to patch up weak points or reopen issues already canvassed or capable of determination on the record. The Court found the present application fell squarely within that prohibition because the appeal could be fully determined on the existing pleadings, proceedings and rulings.
Legal principles established
#- Additional evidence on appeal is admitted sparingly, only where it is shown to be unavailable despite due diligence, relevant and necessary to determine the appeal, and not merely intended to fill gaps or strengthen a party's case.
- A party cannot reopen issues already canvassed and determined in prior proceedings before the trial court through the mechanism of additional evidence on appeal.
- Evidence that formed part of the record before the trial court is not 'additional evidence' within the meaning of Rule 31; if it was not on the record, a satisfactory explanation for its omission at trial is required.
