Summary
In Sa’adiah bte Jamari v Public Prosecutor [2022] SGHC 88, the High Court dismissed an appeal against conviction and sentence arising from two charges under s 328 of the Penal Code. The appellant, a freelance nurse and babysitter, was convicted of administering poisons to two babies, BB1 (aged five months) and BB2 (aged 11 months), with intent to cause hurt. The court imposed consecutive sentences of three and a half years’ imprisonment for each charge, resulting in a total of seven years’ imprisonment.
The appeal turned on two main themes. First, the appellant challenged the admissibility and propriety of the Prosecution’s reliance on a toxicology report (“the Report”) generated from blood and urine samples taken from her after she made a police report alleging a sexual assault against her. She argued that the Report should not be used to prove a separate offence against her. Second, she challenged the sufficiency and assessment of the evidence linking her to the administration of multiple drugs found in the victims’ bodies.
The High Court held that it was open to the Prosecution to rely on the Report in the present case. While the judge expressed reservations about the extent to which information obtained in one investigation could be used in another set of proceedings, the court found that excluding the Report would not have affected the correctness of the conviction. On the evidence as a whole, the court upheld the conviction and found no basis to interfere with sentence.
What Were the Facts of This Case?
The appellant was a trained nurse with a diploma in Nursing and had been enrolled with the Singapore Nursing Board since 2002. At the material time, she worked as a freelance nurse and advertised babysitting services online in 2016. She lived in Hougang with her two teenage daughters. In late 2016, she was engaged by the mothers of two babies—BB1 and BB2—to provide babysitting services at her home.
For BB1, the mother (M1) began sending BB1 to the appellant’s home for babysitting in early November 2016. The appellant babysat BB1 and her sister on eight occasions between 7 November and 9 December 2016. The appellant was the primary caregiver and prepared BB1’s milk personally on most occasions. It was agreed that neither the appellant nor her daughters administered any poisons or stupefying, intoxicating, or unwholesome drugs to BB1 during those sessions.
On 22 November 2016, M1 brought BB1 to KK Women’s and Children’s Hospital (KKH) because BB1 was behaving unusually. KKH took a blood sample but did not test for medication or drugs; no unusual findings were reported. On 9 December 2016, after BB1 was picked up from the appellant’s home and found to be unnaturally drowsy, M1 took BB1 to Parkway East Hospital (PEH). BB1 was admitted and treated; a medical memo later described BB1 as drowsy, floppy, and unable to follow objects. A blood sample taken on 9 December 2016 and analysed by the Health Sciences Authority (HSA) revealed a range of substances, including benzodiazepines and other drug classes (such as alprazolam, diazepam, nordiazepam, oxazepam, temazepam, zolpidem, chlorpheniramine, (dextro)methorphan, orphenadrine, triprolidine, and (pseudo)ephedrine). BB1 responded well to treatment and was discharged on 13 December 2016.
For BB2, the mother (M2) posted in a Facebook group seeking babysitting on 25 December 2016. The appellant responded, and M2 sent BB2 to the appellant’s home that night. Dr Peter Looi was also present in the home but was not involved in BB2’s care. As with BB1, it was agreed that the appellant and her daughters did not administer poisons or stupefying, intoxicating, or unwholesome drugs to BB2. On 26 December 2016, BB2’s father picked BB2 up and observed that BB2 was drowsy with droopy eyelids, truncal ataxia, and difficulty walking. BB2 was admitted to KKH and treated. HSA analysis of a urine sample (28 December 2016) and a blood sample (29 December 2016) detected multiple substances, including alprazolam and several benzodiazepines. BB2 was discharged on 1 January 2017.
What Were the Key Legal Issues?
The first and most legally intricate issue concerned evidence admissibility and propriety. The Prosecution relied on a toxicology Report based on blood and urine samples collected from the appellant about two to three months before the offences. The samples were obtained after the appellant reported to the police that she had been sexually assaulted and cooperated with medical testing. The question was whether it was open to law enforcement and the Prosecution to rely on information obtained in that context to prove a wholly separate offence against the appellant—namely, administering poisons to the babies.
Within that broader question, the court had to consider multiple sub-issues: whether the Report was relevant and admissible; whether any privilege against self-incrimination or related protections applied; whether the Report could be treated as similar fact evidence (and if so, whether it met the requirements for admission); and whether the court should exercise an exclusionary discretion to prevent unfairness. The appellant also raised a privacy or confidentiality dimension, arguing that information derived from one’s body should not be used beyond the purpose for which it was obtained.
The second issue concerned the overall assessment of the evidence. Even if the Report were excluded, the court needed to determine whether the remaining evidence—such as the victims’ symptoms, the timing of symptoms relative to the babysitting periods, the drug substances detected in the victims’ blood and urine, and the items seized from the appellant’s home—was sufficient to prove beyond reasonable doubt that the appellant administered the relevant drugs with intent to cause hurt under s 328.
How Did the Court Analyse the Issues?
The High Court approached the admissibility question by recognising the practical and doctrinal tension: on one hand, evidence obtained from a person’s body may be probative of that person’s involvement in later offences; on the other hand, using such evidence across investigations risks undermining fairness, privacy, and the integrity of investigative processes. The judge noted that the applicable rules of law did not categorically preclude reliance on the Report. However, the court also acknowledged reservations about the extent to which law enforcement agencies or the Prosecution may use information obtained in one investigation in another set of proceedings.
In analysing relevance and admissibility, the court treated the Report as capable of showing that drugs found in the victims’ bodies were also present in the appellant’s system. That linkage was important because the Prosecution’s case was not merely that the victims had been drugged, but that the appellant had access to and administered the drugs. The judge therefore accepted that the Report had evidential value. The court then considered whether any exclusionary rule should apply, including arguments framed around privilege against self-incrimination and the fairness of using information obtained following a complaint by the appellant.
On privilege and fairness, the court did not accept that the Report was automatically inadmissible. The reasoning reflected a distinction between the existence of protections against compelled self-incrimination and the admissibility of evidence that is otherwise relevant and obtained through cooperation in an investigation. The judge’s approach suggests that the court was not prepared to create a broad exclusionary principle that would prevent the Prosecution from using medical or toxicological information simply because it arose from a separate complaint made by the accused.
Turning to similar fact evidence and the court’s exclusionary discretion, the judge considered whether the Report’s use risked unfair prejudice. Similar fact principles typically require careful safeguards because evidence of prior conduct or circumstances may lead a fact-finder to reason impermissibly from propensity. Here, however, the Report was not used to show “propensity” in the conventional sense; rather, it was used to show access and contemporaneous presence of drugs in the appellant’s body, which was directly connected to the charged conduct. The court therefore found no basis to exclude the Report on that ground.
Crucially, the court also addressed the effect of exclusion. Even assuming arguendo that there were concerns about propriety, the judge concluded that excluding the Report would not have affected the correctness of the conviction. This “no material effect” conclusion is significant: it indicates that the court’s decision was anchored in the totality of the evidence, not solely on the Report. The court’s reservations about investigative cross-use did not translate into a miscarriage of justice.
On the substantive evidence, the court examined timing and corroboration. The victims’ mothers testified consistently that the babies were normal when delivered to the appellant’s care and became unusually drowsy when collected. Their observations were supported by contemporaneous messages to the appellant and by the fact that they sought medical attention promptly. The court also considered the drug profile detected in the victims’ blood and urine shortly after leaving the appellant’s care. The presence of multiple drug classes, including benzodiazepines and sedating antihistamines, was treated as consistent with deliberate administration rather than accidental exposure.
The court further considered the appellant’s access to drugs. It was agreed that the appellant was prescribed certain drugs (including zolpidem and alprazolam, as well as diazepam) by a medical centre. In addition, some substances were available over the counter at pharmacies, including (pseudo)ephedrine, (dextro)methorphan, and triprolidine. The court also relied on seized items from the appellant’s home, including an empty slab of zolpidem, a slab of chlorpheniramine with tablets, and other materials on which diazepam and zolpidem were detected. These findings supported the Prosecution’s narrative that the appellant had the means to administer the drugs found in the victims.
Finally, the court addressed the appellant’s explanations. The judgment extract indicates that the appellant did not provide a satisfactory explanation for certain seized items, including a milk bottle with traces of zolpidem. While the full reasoning is not reproduced in the extract provided, the judge’s conclusion that the conviction was correct implies that the court found the defence explanations insufficient to create reasonable doubt, especially given the corroborated timing of symptoms and the drug evidence.
What Was the Outcome?
The High Court dismissed the appeal in its entirety. It upheld the appellant’s convictions under s 328 of the Penal Code for administering poisons to BB1 and BB2 with intent to cause hurt. The court also found no basis to interfere with sentence.
Practically, the appellant remained subject to the consecutive custodial term of seven years’ imprisonment (three and a half years for each charge). The decision confirms that, where the evidence as a whole establishes access, administration, and intent, the court will not necessarily exclude evidence merely because it originated from a separate investigation involving the accused’s own complaint.
Why Does This Case Matter?
Sa’adiah bte Jamari v Public Prosecutor is important for practitioners because it addresses the admissibility and propriety of using toxicology or medical information obtained in one investigative context to prove a different offence. The court’s holding that it was “open” for the Prosecution to rely on the Report provides guidance on how Singapore courts may treat evidence derived from samples taken after an accused reports a crime against her body.
At the same time, the judgment is notable for its candid reservations. The judge accepted that the legal framework did not preclude reliance, but expressed concern about the extent to which law enforcement agencies or the Prosecution may use information obtained in one investigation in another set of proceedings. This signals that, while admissibility may be technically available, courts may still scrutinise investigative conduct and fairness considerations. For defence counsel, the case underscores the value of raising exclusionary arguments, even if the ultimate outcome depends on whether exclusion would be “material” to the verdict.
For prosecutors, the decision supports the proposition that relevant toxicological evidence can be used to establish access and involvement in drug-related offences, particularly where corroborated by timing, symptoms, and physical evidence. For law students and researchers, the case illustrates how courts integrate evidence admissibility analysis with the broader “case as a whole” assessment, including whether any evidential error would have affected the correctness of the conviction.
