George Karori Wainaina v Republic [1978] KECA 10 (KLR)
The bottom line
#Kenya's Court of Appeal confirmed a conviction for stolen goods could rest on handwriting expert evidence alone, because no law requires that evidence to be corroborated.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the opinion evidence of a handwriting expert requires corroboration as a matter of law before a conviction can rest on it
- 2.What the proper limits of a handwriting expert's opinion evidence are
- 3.Whether the appellant's conviction was supported by evidence establishing his connection with the crime beyond reasonable doubt
Key legal issues
#Whether handwriting expert evidence requires corroboration
No rule of law requires corroboration of a handwriting expert's opinion; the court is free to accept or reject it like any expert evidence.
The court distinguished between a rule of law mandating corroboration and the ordinary judicial task of assessing expert opinion. The magistrate and the two judges on first appeal had carefully examined the evidence and used the expert's evidence as guidance, finding the appellant's connection with the crime established beyond reasonable doubt through the false documents made in his own handwriting, in addition to his opportunity arising from his duties.
The proper limits of a handwriting expert's opinion
An expert may say he does not believe a writing was by a particular person, and on the positive side only that two writings are so similar as to be indistinguishable; he cannot definitively say a person wrote a particular thing.
Adopting Spry J in Hussan Salum and Lord Hewart CJ's summing-up in R v Podmore (approved by the English Court of Criminal Appeal), the court held that an expert who says writings were 'in the same hand' goes beyond proper limits. Such a statement is properly read as meaning the writings were indistinguishable from the specimens examined. Here the train sheet authorship was not even disputed.
Legal principles established
#- There is no rule of law requiring corroboration of the opinion of a handwriting expert; such evidence is like other expert evidence, open to the court to accept or reject.
- The proper positive limit of handwriting expert opinion is that two writings are so similar as to be indistinguishable; an expert cannot properly say definitely that a particular person wrote a particular thing.
Court orders
#- 1.Appeal dismissed
- 2.Conviction for stealing goods in transit upheld
The bench
#One judgment of the whole court — no separate or dissenting opinions.
- On appeal from
- High Court (first appeal from Magistrate's Court)
- Jurisdiction invoked
- Second appellate jurisdiction over a criminal appeal (second appeal against conviction from the High Court)
Relief refused
#The appellant's prayer to have the conviction quashed on the ground that the handwriting expert's evidence was uncorroborated
The court held there is no rule requiring corroboration of handwriting expert evidence; such evidence stands like any expert evidence which the court may accept or reject.
Costs
No costs order recorded in the judgment
Quotable passages
#Verbatim from the judgment, each located to the page it appears on in the official PDF — so these can be cited and checked directly.
In our opinion there is no rule which requires corroboration of the opinion of a handwriting expert whose evidence is like the evidence of the class of other experts which it is open to the Court to accept or reject.
On the positive side, however, the most he could ever say is that two writings are so similar as to be indistinguishable and he could, of course, comment on unusual features which make similarity the more remarkable.
We read this to mean no more than that the handwriting in these two documents was indistinguishable from the specimens of handwriting of the appellant supplied to the handwriting expert in this case.
For these reasons we dismiss this appeal. Appeal dismissed.
