Summary
This case concerned a claim for damages arising from a motor vehicle accident involving multiple parties. The central dispute revolved around the determination of liability between the defendants, specifically whether the actions of the first defendant constituted an intervening act (novus actus interveniens) that severed the chain of causation. The plaintiffs sought recovery for injuries sustained, necessitating a detailed examination of the sequence of events leading to the second accident and the conduct of the drivers involved.
Lai Siu Chiu J held that the first defendant’s decision to depress the accelerator instead of the brake was the operative cause of the second accident. The court emphasized that negligence cases are highly fact-specific, and in this instance, the first defendant’s conduct was deemed an intervening act that absolved the second defendant of liability. Consequently, the court ruled that the first defendant was wholly liable for the plaintiffs' claim. The judgment serves as a practical application of causation principles in tort law, reinforcing that a defendant's distinct, erroneous action can effectively break the causal link between a prior event and subsequent damages.
Timeline of Events

What Were the Facts of This Case?
The case arose from a motor accident involving three vehicles at a MacDonald’s Tea Garden car park on Queensway. The first defendant, driving a Honda Odyssey, was struck from behind by a school bus driven by the second defendant. Following this initial collision, the first defendant accelerated instead of braking, causing his vehicle to strike two other stationary cars and ultimately crushing the first plaintiff, who was standing nearby with her dog.
The first plaintiff, an American citizen, suffered severe injuries that necessitated the amputation of her right leg below the knee. Her husband, the second plaintiff, subsequently sought damages for post-traumatic stress disorder allegedly caused by witnessing the incident and its aftermath.
The first defendant admitted to the criminal charges of rash and negligent driving, claiming he had panicked and experienced a temporary blackout or visual impairment that prevented him from removing his foot from the accelerator. He argued that the second defendant’s initial collision was the catalyst for the entire sequence of events.
The second defendant denied liability for the second accident, contending that the first defendant’s subsequent actions were independent of the initial bus collision. The court was tasked with determining the apportionment of liability between the two defendants, as the first defendant had already consented to interlocutory judgment regarding the plaintiffs' claims.
What Were the Key Legal Issues?
The court was tasked with determining liability for a multi-vehicle accident sequence, focusing on the causal link between two distinct collisions and the potential for an intervening act to sever liability.
- Primary Liability for the First Accident: Whether the first defendant’s maneuver of cutting across the second defendant’s path constituted negligence, or if the second defendant’s driving contributed to the collision.
- Novus Actus Interveniens: Whether the first defendant’s subsequent actions following the first accident constituted an intervening act that broke the chain of causation, thereby absolving the second defendant of liability for the second accident.
- Evidentiary Weight and Admissibility: Whether the expert report from Marks and Associates Limited, not supported by oral testimony, could be admitted as evidence of its truth, and whether adverse inferences should be drawn from the failure to call material witnesses.
How Did the Court Analyse the Issues?
The court began by evaluating the credibility of the parties, noting that the first defendant’s testimony was "wildly inconsistent" and materially changed after a site inspection. The court rejected the first defendant’s reliance on the expert report from Marks and Associates Limited, noting it was not admitted as evidence and that the first defendant’s attempt to introduce it was an improper "second bite of the cherry."
Regarding the first accident, the court found the first defendant wholly liable. The court applied a factual analysis of speed and distance, concluding that the first defendant’s version of events was "logically impossible" given the site measurements. The court accepted the second defendant’s account that the first defendant cut into his path, noting that the second defendant’s failure to include this in his police report was excusable due to language barriers.
The court addressed the second accident through the lens of novus actus interveniens. It held that the first defendant’s act of stepping on the accelerator instead of the brake was a voluntary, intervening act. The court emphasized that "every case of negligence turns on its own facts," and concluded that this act effectively broke the chain of causation.
The court rejected the first defendant’s reliance on Teng Ching Sin and Anor v Leong Kwong Sun [1994] 1 SLR(R) 382, finding that the second defendant was not inattentive. Furthermore, the court distinguished SBS Transit Ltd v Stafford Rosemary Anne Jane [2007] 2 SLR(R) 211 and Mohammad Kassim Bin Sapil v Quah Lai Tee & Others [2003] SGHC 118, ruling that the causal link was severed by the first defendant’s conduct.
Finally, the court drew an adverse inference against the first defendant for failing to call his wife as a witness, noting she was a material witness who could have corroborated his version of events. The court concluded that the first defendant was solely liable for the plaintiffs' claim, as his conduct was the effective cause of the second accident.
What Was the Outcome?
The High Court found the first defendant wholly liable for the plaintiffs' claims, determining that his conduct was the effective cause of the second accident. The court rejected the first defendant's attempts to shift blame or introduce uncorroborated expert evidence, finding his testimony inconsistent and unreliable.
The court ordered that the first defendant bear full liability for the damages. Furthermore, the second defendant was awarded costs against the first defendant, to be taxed on a standard basis unless otherwise agreed.
The finding in every case of negligence turns on its own facts. How a court decides in a case will depend very much on the facts peculiar to the case itself. 78 I therefore accept the submission of the second defendant that the first defendant’s act of stepping on the accelerator, instead of braking the vehicle, constituted an intervening act that effectively broke the chain of causation if there was indeed a causal link between the first and second accidents.
Why Does This Case Matter?
The case serves as a practical application of the doctrine of novus actus interveniens in the context of motor vehicle accidents. It establishes that a driver's deliberate or negligent failure to brake—specifically, the act of accelerating instead of braking—can constitute an intervening act that breaks the chain of causation, even if a prior collision occurred.
The judgment reinforces the evidentiary weight of police reports and contemporaneous accounts over post-hoc rationalizations. It clarifies that a defendant's admission of criminal conviction under s 45A of the Evidence Act does not automatically import the contents of associated expert reports into civil proceedings unless those reports are independently admitted.
For practitioners, the case underscores the necessity of medical evidence when pleading "blackouts" or involuntary physical reactions as a defense in negligence. It also serves as a warning against conflating criminal admissions with civil liability, emphasizing that counsel must be prepared to prove the contents of expert reports independently of criminal records.
Practice Pointers
- Scrutinize Police Reports Early: The court highlighted the danger of relying on contemporaneous police reports that omit critical facts. Counsel should proactively verify the accuracy of these reports with clients immediately, as discrepancies between reports and testimony can be used to impeach credibility.
- Conduct Site Inspections: Where time and distance are contested, rely on court-directed site inspections to establish objective measurements. The court's calculation of reaction time (2.6 seconds) based on physical measurements was pivotal in assessing the feasibility of the defendant's actions.
- Avoid 'Absurd' Explanations for Missing Witnesses: The court negatively viewed the first defendant's excuse for not calling his wife as a witness. Ensure that decisions not to call witnesses are grounded in sound legal strategy rather than questionable interpretations of the Evidence Act.
- Expert Reports Must Be Admissible: Do not assume that including an expert report in an agreed bundle automatically makes its contents admissible evidence. If the expert does not testify, the report may be given little to no weight, especially if it contradicts the court's findings on the facts.
- Pleadings Must Be Comprehensive: The court noted the failure to plead specific allegations (e.g., the 'cutting across' maneuver) in the defence. Ensure all material facts supporting a theory of liability or a break in the chain of causation are explicitly pleaded.
- Novus Actus Interveniens as a Shield: Use the principle of novus actus interveniens to isolate liability. In multi-accident scenarios, focus on whether a party's subsequent conduct (e.g., accelerating instead of braking) constitutes an intervening act that supersedes prior negligence.
Subsequent Treatment and Status
The decision in Erin Brooke Mullin and another v Rosli Bin Salim and another [2012] SGHC 27 is frequently cited in Singapore jurisprudence as a clear application of the novus actus interveniens doctrine in the context of motor vehicle accidents. It serves as a standard reference for the principle that a driver's unreasonable reaction to an initial collision can break the chain of causation, thereby shifting liability for subsequent damage.
The case has been applied in subsequent High Court decisions to emphasize that negligence claims are highly fact-specific. While it does not establish a new legal test, it remains a settled authority for the proposition that an intervening act—such as unintended acceleration—can effectively absolve a prior tortfeasor of liability for the resulting consequences of that second act.
