JDA v Public Prosecutor

JDA married the complainant's mother in October 2003 and they divorced in January 2020. The complainant, his stepdaughter, lived with him, her biological family and her step-siblings at three addresses between 2005 and 2016. She alleged four incidents in which he outraged her modesty: touching her chest in her bedroom at the Green Road address when she was in primary school; rubbing his penis and fingers on her vagina in the master bedroom there; touching her breast and bare thigh in his car at the Blue Road carpark when she was in lower secondary school; and, in 2015 at the Yellow Road unit when she was 19 years old, touching her breast and thigh while she slept beside her stepsister (PW4), who said she saw it. She lodged a police report on 20 May 2021. JDA denied every incident.

The District Judge convicted him on all four charges, finding the complainant unusually convincing and the fourth charge corroborated by PW4, and imposed a global 34 months' imprisonment and six weeks' imprisonment in lieu of caning. He appealed against conviction and sentence in Magistrate's Appeal No 9127 of 2024/01, and the prosecution appealed against sentence in Magistrate's Appeal No 9127 of 2024/02.

1. Whether the complainant's uncorroborated evidence on the first, second and third charges was unusually convincing
2. Whether inconsistencies on matters outside the particulars of a charge are relevant to whether a witness is unusually convincing
3. Whether the complainant's evidence on the fourth charge was corroborated
4. Whether the sentence for the remaining charge, including the term in lieu of caning, was wrong

For the Green Road charges, the complainant's first statement described two incidents involving her vagina and said nothing else happened there. Her third statement, recorded after the charges were drafted, replaced one of them with a chest-touching incident while still speaking of two incidents. There was no evidence of any unrecorded interview to support the first charge, and her explanation that there had been many incidents surfaced only during impeachment. Allowance for faulty memory is not a blank cheque, and the shifting number and nature of the acts raised a reasonable doubt on both charges.

The court held that inconsistencies outside the charge particulars are relevant, relying on AOF v Public Prosecutor [2012] 3 SLR 34 and reading GII v Public Prosecutor [2025] 3 SLR 578 as laying down no bright-line rule. The question is whether they go beyond recalling insignificant details and undermine the core of the evidence. On the car incident, she had presented a touch on her upper arm as the moment she decided to open her eyes, yet at trial she denied it happened and gave a different sequence, so that conviction was set aside.

The fourth charge stood. Her account was largely consistent, and PW4's evidence corroborated it; PW4 had no reason to lie about her own father, and her sleeping position did not make it improbable that she saw him. Accounts of the aftermath by her father and twin brother were broadly consistent, and minor differences in timing were peripheral.

On sentence, there was no premeditation or significant opportunism, as the offence happened where she usually slept. Abuse of trust was present, and the brazenness of touching her while her younger stepsister lay beside her was a further aggravating factor, so 10 months stood. With only one proven incident at age 19, she was not shown to be a particularly vulnerable victim, and there were no substantial aggravating factors to justify enhanced imprisonment in lieu of caning.

The High Court allowed JDA's appeal in part and dismissed the prosecution's appeal. He was acquitted of the first, second and third charges; the conviction on the fourth charge and its 10 months' imprisonment were upheld, but the six weeks' imprisonment in lieu of caning was set aside, leaving a sentence of 10 months' imprisonment.
