Mwangi & another v Wambugu (Civil Appeal 77 of 1982) [1984] KECA 13 (KLR)
The bottom line
#Kenya's Court of Appeal overturned a road accident damages award, holding that a first appeal court can reject a trial judge's findings of fact when the evidence doesn't support them.
What this practically means
#Executive summary
#Key legal issues
#Interference with trial judge's findings of fact on a first appeal
The majority held the trial judge was plainly wrong to reject Inspector Muli's evidence as to the point of impact; his sketch plan was the best evidence and his evidence was subjected to ineffectual cross-examination, so the Court had a duty to interfere.
The Court applied the principle that a first appeal court re-evaluates the evidence while allowing for the trial judge's advantage. Kneller JA found the judge's impression based on the demeanour of Muli and Kihara inconsistent with the evidence generally, including omissions and anomalies in the police file. Potter JA found no sufficient reason to reject Muli's first-hand observations. Hancox JA, dissenting, held the judge was entitled to prefer Kihara and reject Muli.
Liability for the road accident
By majority, the matatu driver (Wambugu) was wholly to blame; the defendants/appellants were not negligent.
Once the trial judge's rejection of Muli's evidence was overturned, the point of impact lay on the bus's proper side of the road. The reconstruction by Inspector Muli, supported by the defence investigators, was the more probable account. The trial judge's contrary findings rested on Kihara, whose evidence the majority found incredible or at least not safe to prefer.
Evidential status of documents admitted by consent
Documents admitted by consent are proved as what they purport to be, but no admission is made as to assertions of fact in them.
The police investigation file was produced without objection. The Court clarified that consent admission saves formal proof of authenticity only; the truth of the contents, including the covering report contradicting Inspector Muli's sketch plan, remains a matter of evidence.
Hearsay and unread witness statements in the police file
The trial judge rightly refused to recall Inspector Muli to read out witnesses' statements, as that would be hearsay; the Evidence Act grounds could not be raised on appeal when not taken below.
The appellants' counsel had not applied under sections 35 and 36 of the Evidence Act at trial, so the ground failed. Hancox JA added that inserting makeweight grounds of appeal assists nobody.
Legal principles established
#- Where a trial judge finds no contributory negligence, an appellate court should not interfere unless satisfied the judge was wrong; if so satisfied, it has a duty to interfere and is not restricted to exceptional cases.
- An appellate judge need not accept the trial judge's findings of fact where the judge failed to take account of material circumstances or probabilities, or where a demeanour-based impression is inconsistent with the evidence generally.
- On a first appeal, the Court of Appeal is obliged to reconsider and re-evaluate the evidence, making due allowance for not having seen or heard the witnesses.
- Where documents are admitted by consent, the admission goes only to their authenticity, not to the truth of assertions of fact contained in them.
