Summary
ACB v Thomson Medical Pte Ltd and others [2015] SGHC 9 concerned a claim arising from a medical error during an in-vitro fertilisation (“IVF”) procedure. The plaintiff, ACB, and her husband sought IVF treatment to conceive additional children. During the IVF cycle that resulted in the birth of “Baby P”, the plaintiff’s egg was fertilised with the sperm of a third-party donor instead of the sperm of the plaintiff’s husband. The plaintiff later discovered the mix-up through physical and blood-type discrepancies and sued the hospital and the embryologists for negligence, and alternatively for breach of contract.
The High Court was asked to determine, as a preliminary issue, whether the plaintiff was legally entitled to claim damages for Baby P’s upkeep. The court accepted that the question should be tried as a preliminary issue because it could potentially dispose of the need for evidence relating to the quantum of upkeep expenses. On the substantive issue, the court addressed competing arguments grounded in public policy, foreseeability, and comparative jurisprudence on “wrongful conception” and “wrongful birth” style claims, including decisions from other common law jurisdictions.
Although the full reasoning in the truncated extract is not reproduced here, the decision ultimately formed part of a broader legal trajectory culminating in the Court of Appeal’s later clarification. The Court of Appeal dismissed the appeal in so far as upkeep costs were concerned, but recognised a different compensatory route: general damages for injury to the plaintiff’s interest in “genetic affinity”. This case therefore sits at the intersection of medical negligence, contractual breach in fertility treatment, and the law’s approach to damages for the costs of raising a child conceived through an error.
What Were the Facts of This Case?
The plaintiff, ACB, is a Singaporean woman of Chinese descent married to a German husband of Caucasian descent. After difficulty conceiving, the couple sought medical advice in 2006 and were advised to try IVF. In 2007, they underwent IVF at Thomson Fertility Centre Pte Ltd, a fertility clinic wholly owned by Thomson Medical Pte Ltd and located within the hospital’s premises. That first IVF cycle was successful and resulted in the birth of a son.
In 2009, the couple returned for another IVF cycle because they wanted more children. In October 2010, the plaintiff delivered a daughter, “Baby P”. The IVF procedure involved the removal of eggs from the woman, fertilisation in a laboratory, and implantation of viable fertilised eggs to establish pregnancy. In this cycle, however, a mistake occurred: the plaintiff’s egg was fertilised with the sperm of a third-party Indian male donor rather than with the sperm of the plaintiff’s husband.
The third defendant, Dr Eleanor Quah, was the senior embryologist responsible for key steps in the process: (1) collection and storage of the bottle containing the husband’s semen; (2) verifying the details on the semen bottle as belonging to the plaintiff’s husband; and (3) fertilising the plaintiff’s egg with the husband’s sperm. The fourth defendant, Dr Chia Choy May, was the Chief Embryologist and supervisor of the embryology team. The plaintiff’s pleaded case was that these professional responsibilities were breached, leading to the genetic mismatch.
After delivery, the couple discovered the error. Baby P’s skin tone and hair colour differed from those of the plaintiff and her husband and from those of their son. In addition, Baby P’s blood type did not match the blood types of the couple. On 4 June 2012, the plaintiff sued the defendants in negligence. She also sued the third defendant for breach of contract in the alternative, relying on the contractual promise to fertilise her egg with her husband’s sperm.
What Were the Key Legal Issues?
The immediate legal issue before Choo Han Teck J was whether the plaintiff was legally entitled to claim damages for Baby P’s upkeep. This was not a question of the amount of upkeep expenses, but of entitlement in principle. The defendants sought to strike out or dispose of the upkeep claim on the basis that it was contrary to public policy, and therefore not recoverable.
Procedurally, the court also had to decide whether the question should be determined as a preliminary issue under O 33 r 2 of the Rules of Court (Cap 322, R 5, 2014 Rev Ed). The defendants argued that a preliminary determination would save time and costs, particularly because expert evidence would be required to quantify upkeep expenses incurred in Beijing and Germany. They also contended that the question was one of law that could be decided independently of the evidence that would otherwise be adduced at the damages assessment stage.
Substantively, the plaintiff’s position required the court to consider whether damages for the costs of raising a child conceived through a medical mix-up could be characterised as recoverable loss in negligence and/or contract. The plaintiff’s arguments drew on public policy considerations, foreseeability, and comparative authority from other jurisdictions that had allowed similar claims in “wrongful conception” contexts.
How Did the Court Analyse the Issues?
First, the court addressed the procedural question. The judge accepted that the preliminary issue should be determined. The reasoning reflected the practical litigation management purpose of O 33 r 2: if the legal entitlement to upkeep damages failed, the parties would not need to proceed to a potentially complex and expensive assessment of quantum. The court also accepted that the legal question could be resolved without waiting for the full evidential record on the costs of upbringing, because the core dispute concerned the recoverability of such damages as a matter of law and public policy.
In doing so, the court distinguished the earlier procedural history. The plaintiff had previously faced strike-out attempts before an Assistant Registrar, where the upkeep claim was treated as contrary to public policy. The plaintiff had appealed only the upkeep-related order, and the High Court had allowed the appeal in ACB v Thomson Medical Pte Ltd and others [2014] SGHC 36. That earlier decision emphasised that it was inappropriate to hear damages-related reasonableness issues in isolation where liability and damages were connected. In the present decision, however, the court was now dealing with a preliminary legal entitlement question, after the pleadings and procedural posture had evolved.
Second, the court turned to the substantive entitlement question. The plaintiff advanced multiple grounds. One argument was that the upkeep claim should be allowed in tort because it involved reasonably foreseeable damage. The plaintiff relied on the Termination of Pregnancy Act (Cap 324, 1985 Rev Ed) (“TPA”) to support a public policy narrative: the TPA gives a woman the right to decide whether to terminate a pregnancy. The plaintiff argued that the TPA “marks out” public perception towards abortion. On this view, if the error had been discovered early enough, the plaintiff could have terminated the pregnancy; once that opportunity passed, the defendants should contemplate that someone would be obliged to bring up the child.
Third, the plaintiff urged the court to follow the majority decision in Cattanach v Melchior [2003] 215 CLR 1 (High Court of Australia), which had allowed a claim for the expenses of bringing up a child conceived after negligent advice that sterilisation was complete. The plaintiff also argued that the contrary House of Lords decision in McFarlane v Tayside Health Board [2000] 2 AC 59 should not be followed. The plaintiff’s critique of McFarlane included that it was constrained by the English reluctance to allow claims for pure economic loss, whereas Singapore’s approach differs. The plaintiff relied on Spandeck Engineering (S) Pte Ltd v Defence Science & Technology Agency [2007] 4 SLR 100 to support the proposition that Singapore courts are more willing to allow claims for pure economic loss than English courts.
Although the extract provided is truncated, the structure of the plaintiff’s submissions indicates that the court was required to weigh (i) the foreseeability and causation of the claimed loss, (ii) whether the law should treat the costs of raising a child as recoverable damages, and (iii) whether public policy should bar such recovery. The court also had to consider how to frame the loss: whether it is a form of economic loss flowing from the defendant’s breach, or whether it is conceptually problematic because it involves valuing the existence of a child and the moral and social implications of such valuation.
In this context, the court’s analysis would necessarily engage with the broader doctrinal tension in wrongful conception/wrongful birth jurisprudence: the law must reconcile compensating a claimant for legally recognised loss with avoiding outcomes that appear to treat the birth of a child as a compensable harm. The public policy argument advanced by the defendants, accepted at earlier stages, suggested that such damages are not recoverable. The plaintiff’s counter-arguments sought to reframe the claim as compensation for the consequences of the medical error, rather than a negative valuation of the child’s life.
What Was the Outcome?
The High Court’s decision in [2015] SGHC 9 resolved the preliminary issue concerning entitlement to claim damages for Baby P’s upkeep. The litigation did not end there: the matter proceeded to the Court of Appeal, which later dismissed the appeal in so far as upkeep costs were concerned. This indicates that the final appellate position did not permit recovery of upkeep expenses in the way the plaintiff had sought.
However, the Court of Appeal recognised an alternative compensatory basis. It acknowledged the appellant’s right to claim, as general damages, a sum in recompense of the injury suffered to her interest in “genetic affinity”. Practically, this means that while the law did not allow the plaintiff to recover the full costs of raising the child, it still provided a route for monetary compensation for the non-economic injury arising from the genetic mismatch caused by the medical error.
Why Does This Case Matter?
ACB v Thomson Medical Pte Ltd and others [2015] SGHC 9 is significant for practitioners because it illustrates how Singapore courts approach damages in medical negligence and fertility treatment cases where the injury is not merely physical harm but also involves genetic and relational interests. The case highlights that even where liability may be established, the law may still restrict the categories of recoverable loss on public policy grounds, particularly where damages would effectively require the court to award the costs of bringing up a child.
From a doctrinal perspective, the case demonstrates the importance of how claims are framed. The plaintiff’s reliance on comparative authorities such as Cattanach and the critique of McFarlane show that the recoverability of upbringing costs has been debated across jurisdictions. Singapore’s eventual appellate direction—denying upkeep costs but allowing general damages for injury to genetic affinity—reflects a calibrated approach: compensating the wrong without endorsing a damages model that values parenthood through a cost-based metric.
For litigators, the case also underscores procedural strategy. The court’s acceptance that the upkeep entitlement question should be tried as a preliminary issue shows that courts will consider efficiency and the avoidance of unnecessary expert evidence. This is particularly relevant in medical negligence cases where damages assessment can be complex, involving foreign living costs, education planning, and long-term care assumptions.
