Wambua Musili v Republic [2020] KECA 702 (KLR)
The bottom line
#Kenya's Court of Appeal overturned a life sentence because the trial court convicted the accused without first obtaining a proper psychiatrist's report on his mental fitness.
What this practically means
#Executive summary
#Key legal issues
#Validity of the plea-taking process where the accused's mental fitness had been questioned and a psychiatrist's report had been ordered but never obtained
The plea-taking process in the trial court and the appellate proceedings before the High Court were both vitiated for failure to follow the correct procedure on mental status; the conviction and sentence were set aside and a retrial ordered.
The trial court had directed a psychiatrist's examination; no such report was tendered, only a handwritten opinion of a non-psychiatrist medical officer on plain paper. In the absence of an order varying its own direction, the trial court's hands were tied and it could not act on any other report. It was obliged to defer plea-taking until a psychiatrist's report was availed. The High Court likewise erred in sweeping aside two psychiatric reports it had itself called for. Section 162 of the CPC required an inquiry into unsoundness, and section 280(1) applies mutatis mutandis to first appeals. Both processes therefore stood vitiated.
Whether retrial or acquittal was the appropriate remedy
A retrial was ordered, applying the principle that retrial depends on the facts of each case and should be made where the interests of justice require.
Having vitiated the plea-taking and appellate processes, the court balanced the interests of the appellant and the complainant. Relying on Benard Lolimo Ekimat v R and Muiruri v R, it held that retrial depends on the particular facts and circumstances, and the interests of justice would best be served by a retrial given that the proceedings below were vitiated by failure to follow the correct procedure on mental status. The retrial was directed before a magistrate other than H.M. Nyaberi, PM.
Scope of a second appeal
The Court declined to delve into the merits, restating that a second appeal is confined to points of law and it will not interfere with concurrent findings of fact unless based on no evidence, misapprehension of evidence, or wrong principles.
The Court invoked Kaingo v R and Reuben Karari to frame its mandate. Although its jurisdiction is limited, the failure by both courts below to follow the statutory procedure on mental fitness constituted errors of law sufficient to engage the Court's intervention. On that footing the Court did not consider it appropriate to delve into the merits of the appeal.
Legal principles established
#- A second appeal is confined to points of law and the Court will not interfere with concurrent findings of fact of the two courts below unless based on no evidence, a misapprehension of the evidence, or demonstrably wrong principles.
- Where a trial court has ordered a psychiatric examination to determine an accused's mental status before plea, it cannot act on a medical report from a practitioner who is not a psychiatrist, and must defer plea-taking until a psychiatrist's report is availed.
- When an accused's mental instability is raised, the court must conduct an inquiry under section 162 of the CPC before deciding whether to proceed with the plea or take other action under section 167.
- An order for retrial is discretionary and should only be made where the interests of justice require it and where it is unlikely to cause injustice to the appellant.
