Personal injury law evolves not through abrupt change, but through careful calibration. One of the most notable developments in recent years was the introduction of the Singapore Actuarial Tables, which replaced traditional methods of estimating future financial loss.
The case of Muhammad Adam bin Muhammad Lee v Tay Jia Rong Sean was heard at a pivotal moment in this transition. In 2021, during the course of the proceedings, the Actuarial Tables were published.
We sought to rely on these newly issued tables to support higher multipliers for future medical expenses and income loss. However, the evidentiary hearing had concluded before the tables came into force. The Court declined to apply them retrospectively, holding that doing so would cause irremediable prejudice to the defendant.
While the Court adhered strictly to procedural fairness, it did not ignore economic reality. Acknowledging the low interest rate environment at the time, the judge adjusted the traditional discount rate modestly to arrive at a fairer outcome within the confines of the existing framework.
Viewed from our current practice in 2026, this judgment illustrates the balance courts must strike. Legal innovation must not undermine procedural justice. At the same time, rigid adherence to outdated assumptions risks under compensation.
The subsequent adoption of the Actuarial Tables has since brought greater consistency and predictability to damage assessment. For younger lawyers, this case remains a useful teaching moment. It shows how courts manage transition. Progress is embraced, but never at the expense of fairness. That balance is what allows the law to evolve with legitimacy.
