David Mwingirwa v Republic [2017] KECA 666 (KLR)
The bottom line
#Kenya's Court of Appeal freed a man sentenced to life for incest, ruling a broken hymen alone cannot prove defilement and prosecutors must call key witnesses.
What this practically means
#Executive summary
#Key legal issues
#Duty of the first appellate court
The High Court failed to independently evaluate the evidence; it accepted the prosecution case wholesale, gave the appellant's defence short shrift, and proceeded on a theory of its own contrary to the evidence, which were reversible errors.
The Court found that although the judge cited Okeno vs Republic, she did not apply it: she placed undue weight on the broken hymen, invented a motive for the complaint without evidential basis, and disposed of the defence in a single peremptory sentence. A first appellate court must weigh conflicting evidence, draw its own conclusions, and give real consideration to the accused's defence.
Evidential value of a broken hymen
A broken hymen alone is not conclusive proof of defilement; it may be ruptured by causes other than sexual intercourse.
Following P.K.W vs R, the Court held that medical and scientific evidence shows some girls are born without a hymen and it can be torn by tampons, masturbation injury, medical examination, vigorous physical activity or natural tearing. The Clinical Officer's evidence went no further than a suggestion, and the judge erred in founding a firm conclusion of defilement on the hymen alone.
Failure to call witnesses
Section 143 of the Evidence Act does not relieve the prosecution of the duty to call a sufficiency of evidence; where crucial eyewitnesses are not called and not explained, an adverse inference arises and the conviction becomes unsafe.
Kathure and her husband were alleged eyewitnesses whose evidence would have been critical on visibility through the wall cracks and on the neighbours' strange inaction; the complainant's sister was also in the house. No explanation was given for their non-calling. Applying Bukenya vs Uganda, the Court held the evidence was barely adequate and the omission fatal.
Legality of the life sentence
Section 20(1) of the Sexual Offences Act prescribes a maximum, not a mandatory, life imprisonment where the offender is 'liable to' life imprisonment.
Counsel for the Republic argued the sentence was mandatory; the Court corrected this, relying on Daniel Kyalo Mwema vs R, holding that 'liable to' connotes a maximum penalty rather than a mandatory one. This point did not affect the outcome since the conviction itself was quashed.
Legal principles established
#- A second appeal is confined to matters of law and the Court will not interfere with concurrent findings of fact unless based on no evidence.
- A broken hymen is not, without more, conclusive proof of penetrative sexual intercourse; the first appellate court erred in treating it as such.
- Where the prosecution calls barely adequate evidence and fails to call available crucial witnesses without explanation, the court is entitled to draw the adverse inference that their evidence would have been adverse to the prosecution.
- The first appellate court must independently and exhaustively re-evaluate the evidence, including the defence, and not merely endorse the trial court's findings.
- 'Liable to' a sentence connotes a maximum, not a mandatory, sentence.
