R v Jia Xin Teo

Significant planning or premeditation does not require a comprehensive plan, special preparations, or pre-purchased means. It may be inferred from a settled course of conduct directed to concealing a pregnancy and disposing of a child. In fixing a murder minimum term, the sentencing judge must assess the aggravating and mitigating factors overall. The exercise is evaluative rather than mechanistic. Adequate reasons may identify the relevant factors and explain the overall conclusion without specifying a precise adjustment for each factor. A mother’s betrayal of the trust owed to a newborn child is a weighty aggravating feature.

The applicant was convicted of murder at the Crown Court at Warwick on 24 October 2024 and sentenced the following day to life imprisonment with a minimum term of 17 years, less 230 days spent on remand. The statutory starting point under Schedule 21 to the Sentencing Act 2020 was 15 years. Permission to appeal against sentence was refused by a single judge.

The applicant applied to the Court of Appeal (Criminal Division), arguing that the sentencing judge had wrongly found significant planning or premeditation and had failed to give proper effect to her mitigation, including mental ill-health, youth, good character, vulnerability, and the absence of family support in the United Kingdom. The central issues were whether the finding of planning was open to the judge and whether the resulting uplift was unjust or disproportionate.

1. Application refused. The single judge was correct that the proposed appeal was not properly arguable.

2. The sentencing judge was entitled to conclude, to the criminal standard, that the applicant had formed a settled plan well before the birth. The plan was to conceal the pregnancy, ensure that nobody knew of the birth, and get rid of the baby. Significant planning did not require a comprehensive or detailed plan, specially obtained accommodation, internet research, or items purchased for the killing or concealment. The applicant’s conduct before and after the birth could properly be viewed as the implementation of one longer-term plan. The court rejected the suggested distinction between that plan and the events in the bathroom.

3. The judge’s conclusion was supported by clear, lucid, coherent, and cogent reasons. The fact that the judge also described the applicant as being in denial did not make the finding inconsistent. That observation provided context for the motivation and development of the plan.

4. In fixing the minimum term under Schedule 21 to the Sentencing Act 2020, the judge was required to form an overall view of the aggravating and mitigating factors. The applicant’s position as the mother of a newborn child created a critically important relationship of trust. The child’s age and vulnerability made the betrayal of that trust a significant and weighty aggravating feature.

5. The judge had taken account of the applicant’s mental ill-health, age, good character, vulnerability, the lifelong consequences of the conviction, and the additional hardship arising from her family’s residence in Malaysia. The conclusion that the aggravating factors materially outweighed the mitigation, justifying an uplift from the 15-year starting point, was unimpeachable. Sentencing was an evaluative exercise and was not susceptible to mechanistic analysis of particular upward and downward adjustments. The reasons were adequate, and the 17-year minimum term was reasonable and proportionate.

1. Court of Appeal (Criminal Division): on [2026] EWCA Crim 134, refused the application for leave to appeal against sentence.
2. Crown Court at Warwick: on 24 October 2024, convicted the applicant of murder; on 25 October 2024, imposed life imprisonment with a 17-year minimum term, less 230 days spent on remand.
