Okumu v Republic (Criminal Appeal 178 of 2018) [2023] KECA 353 (KLR)
The bottom line
#Kenya's Court of Appeal quashed a 15-year defilement conviction because the P3 form and age report were produced by the wrong witness.
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 P3 form and age assessment report were properly admitted as exhibits
- 2.Whether the offence was proved
- 3.Whether the appellant has met the limited conditions that allow the court to interfere with the sentence
Key legal issues
#Admissibility and probative value of expert documents produced by a non-maker
The P3 form and age assessment report were irregularly produced by the investigating officer; no basis was laid under section 33 of the Evidence Act, the exhibits had no probative value, and the appellant's fair-trial rights under article 50(2)(k) were violated.
Section 77 of the Evidence Act concerns authenticity, not production procedure. A document produced without its maker has lower probative value because it cannot be tested by cross-examination. Where the maker is unavailable, section 33 requires a foundation and production by another expert familiar with the author's hand. No such basis was laid; the appellant, acting in person, could not meaningfully cross-examine PW3, a police officer. The failure denied the appellant the article 50(2)(k) right to challenge evidence.
Whether the offence was proved beyond reasonable doubt absent the impugned exhibits
Without the P3 form and age assessment report, only the complainant's evidence remained; her standalone evidence, weighed against the defence and the alleged coercion in reporting, left doubt, so the conviction could not stand.
Although sexual offences may be proved by a complainant's evidence alone, corroboration ordinarily affirms it. The age of the complainant in particular ought to be corroborated. The complainant's submission that she named the appellant under threat of corporal punishment from her mother could not be ignored. Discarding the irregular exhibits, the residual evidence did not establish guilt beyond reasonable doubt.
Sentence
The sentence could not stand once the conviction was quashed; the appeal on sentence was rendered moot by the success on conviction.
Since the appeal against conviction succeeded, the sentence of 15 years necessarily fell with it. The court did not need to reach the merits of the sentencing challenge.
Legal principles established
#- A document produced in the absence of its maker carries lower probative value; before a report may be produced by a person other than its maker, a foundation must be laid under section 33 of the Evidence Act, and the court must assess genuineness under section 77(2).
- Where medical documents are irregularly produced and carry no probative value, the evidence remaining must independently prove the offence beyond reasonable doubt; in this case it could not, and the conviction could not stand.
Court orders
#- 1.The appeal against conviction is allowed; the conviction is quashed
- 2.The sentence of 15 years is set aside
- 3.The appellant is set at liberty forthwith unless otherwise held on a lawful warrant

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 view, therefore, precedent to the operation of section 77 of the Evidence Act is a condition set under section 33 of the Evidence Act.
In the circumstances, we reach the conclusion that the P3 form and age assessment report were irregularly produced. Further, that the procedure adopted for the production of the exhibits was prejudicial to the appellant. Therefore, the exhibits had no probative value in the case.
Looked at from the constitutional perspective, the appellant’s right to a fair trial was violated as he was denied right guaranteed to every accused person by article 50(2)(k) of the Constitution to adduce and challenge evidence.
The appropriate conclusion therefore is to allow the appeal by quashing the conviction and setting aside the sentence. The appellant is hereby set at liberty forthwith unless otherwise held on a lawful warrant. It is so ordered.
Issues in the judgment
#The case number of the appeal in this Court is not stated anywhere in the judgment provided
The judgment contains typographical errors rendering 'offence' as 'ofience' and 'officer' as 'ofiencer/oficer' throughout
