What this practically means
#Executive summary
#Key legal issues
#Availability and efficacy of the statutory defence under section 8(5) and (6) of the Sexual Offences Act
The defence was established: the complainant lied about her age, her mother confirmed she was 18, and the surrounding circumstances justified a reasonable belief that she was over 18, discharging the accused's burden on a balance of probabilities.
The appellant asked the complainant her age and was told she was 19; her mother told him she was 18 and not schooling. The prosecution introduced the age question and offered nothing to show the belief was unreasonable. The mother's conduct - permitting courtship visits, sending the complainant's clothes, and delaying the report amid dowry negotiations - supported the reasonable belief. The trial courts erred by demanding an age assessment, a requirement the Court found baffling and unsupported.
Standard and burden of proof applicable to the section 8(5) defence
The accused's burden on the statutory defence is on a balance of probabilities, while the ultimate burden in a criminal trial always remains on the prosecution beyond reasonable doubt.
The High Court judgment gave no indication of the standard of proof expected of the appellant, a crucial non-direction. Had the Judge applied the correct standard, he would have found that the appellant was more likely than not deceived by the complainant's express lie. Placing too heavy a burden on the accused to prove the defence inverted the criminal burden of proof and rendered the conviction unsafe.
Safety of the conviction
The conviction was unsafe and could not stand.
Given the uncontradicted evidence of deception and reasonable belief, and the High Court's unsatisfactory treatment of the defence and the applicable standard of proof, the Court concluded that the conviction could not be sustained and the sentence of 20 years imprisonment had to fall with it.
Legal principles established
#- Once an accused person gives evidence indicating that the child expressly deceived him into believing she was over 18 years, it is for the prosecution to disprove that deception.
- An accused person's burden in invoking the defence under section 8(5) and (6) of the Sexual Offences Act is discharged on a balance of probabilities.
- The ultimate burden of proof in a criminal trial always rests with the prosecution to prove its case beyond reasonable doubt, and courts must not place too heavy a burden on an accused to prove a statutory defence.
