Summary
In Chan Susan v Lai Tet Chong and another ([2012] SGHC 139), the High Court dismissed a negligence claim brought by a bus passenger who fell while attempting to catch a bus. The plaintiff alleged that the bus driver shut the front boarding door without warning and drove off, causing her to lose her balance and be run over. The defendants denied causation and relied on the driver’s account and a video recording of the incident.
The court’s central task was to determine whether the driver caused the plaintiff’s fall and, if causation were established, whether the driver breached a duty of care. After reviewing the video repeatedly and comparing it with the plaintiff’s pleadings and evidence, the judge found that the plaintiff’s account was inconsistent with the objective evidence and that the driver had not caused the fall. Even if the plaintiff’s fall were linked to the bus’s movement, the court held that the circumstances did not show negligent responsibility: the accident happened too quickly for the driver to avoid it, and the driver was not obliged to stop in the absence of a reasonable opportunity to prevent injury.
What Were the Facts of This Case?
The plaintiff, Chan Susan, fell on 14 March 2010 at around 9.00am while trying to board a bus (SBS 655L) owned by the second defendant. The first defendant was the driver of the bus at the material time. The plaintiff sued both defendants for damages in negligence, alleging that the driver shut the front boarding door without warning and then drove off, which caused her to lose her balance and fall, with the result that she was run over by the bus.
In her Statement of Claim and in her affidavit of evidence-in-chief, the plaintiff’s pleaded narrative was that she approached the bus stop along Tanjong Katong Road intending to board the bus. She claimed that the driver shut the front boarding door without warning and drove off, causing her to fall. She further asserted, twice in her affidavit, that one of her legs was on the steps of the bus when the bus suddenly and without warning started to move off. According to her account, this sudden movement caused her to lose her balance.
During the proceedings, the defendants challenged the plaintiff’s credibility and consistency. The defendants pointed out that the plaintiff’s evidence was inconsistent with a police report made by her and with the averments in her Statement of Claim. The plaintiff later amended her affidavit of evidence-in-chief, and the judge noted that the amendment “embellish[ed]” her account by introducing a clearly untrue version: that the bus driver stopped the bus and allowed her to put one foot on the bus, but drove off before she could board. The court treated these inconsistencies as significant in assessing whether the plaintiff’s account could be accepted.
In response, the defendants’ case was that the bus had already started moving because there were no more passengers alighting or boarding. The defendants’ position was that the bus could not move unless both doors were shut. The first defendant testified that the plaintiff ran from behind the bus and slipped while attempting to catch it before it left. The defendants also produced a video clip recorded by another bus driver, filmed from a bus travelling behind SBS 665L. The video was shown in court and the judge watched it multiple times, focusing on different aspects of the incident.
What Were the Key Legal Issues?
The case turned on a single, practical issue: whether the first defendant caused the plaintiff’s fall and, consequently, her injuries. Although negligence law typically involves multiple elements—duty, breach, causation, and damage—the judge framed the trial as essentially focused on causation. This framing reflected the evidential dispute: the plaintiff’s pleaded mechanism of injury (door closure and sudden departure while she had a leg on the steps) was contested by the defendants’ account and contradicted by the video.
Accordingly, the court had to decide whether the plaintiff’s evidence was reliable and whether the objective evidence demonstrated that the driver’s actions caused the fall. If causation were established, the court would then need to consider whether the driver was negligent—specifically, whether the driver breached any duty of care by failing to prevent the injury. The judge indicated that even if causation were shown, the defendants could still succeed if the circumstances did not demonstrate negligent responsibility or if the driver had no reasonable opportunity to avoid the injury.
Thus, the legal issues were twofold: (1) causation—did the driver shut the door and drive off in a manner that caused the plaintiff to fall? and (2) negligence—if the driver’s conduct were causally linked to the injury, was it a breach of duty, or was the injury not reasonably avoidable in the time available?
How Did the Court Analyse the Issues?
The judge’s analysis began with the evidence, particularly the video clip. The court observed that the video showed the plaintiff walking along the pavement towards the bus stop while passengers were alighting from the bus (SBS 665L). Importantly, the judge found that the plaintiff was not in a queue as she had averred in her evidence-in-chief and police report. The video further showed that when it appeared there were no passengers at the boarding door in the front of the bus and the last passenger had alighted, the driver shut the doors and the bus began to move. The judge treated the timing as crucial: it was almost simultaneously that the plaintiff realised the bus was moving and began to run.
Based on the video, the judge concluded that the plaintiff started running when the bus was already about to move or had begun moving. The plaintiff was at or slightly ahead of the rear door when she started running. She then lost her footing because she was running too close to the edge of the pavement and fell. At the point she fell, the judge found that she had not reached the front door of the bus. This factual sequence directly undermined the plaintiff’s pleaded mechanism of injury, which depended on the driver shutting the front boarding door without warning and driving off while she had a leg on the steps.
The judge also addressed the plaintiff’s inconsistencies. The plaintiff’s evidence had shifted, and the judge noted that she amended her affidavit after seeing the video, deleting portions that had supported her earlier account. The judge observed that the video did not show the plaintiff tapping on the bus. Instead, it appeared she was either attempting to tap it or had reached out when she lost her footing, but that motion occurred as she fell. The court’s reasoning suggests that the video not only contradicted the plaintiff’s narrative but also provided a coherent alternative explanation consistent with the defendants’ account: the plaintiff ran after the bus had started to move and fell due to her own footing while running close to the pavement edge.
On causation, the judge stated that he was satisfied that the first defendant (and consequently the second defendant) had not caused the plaintiff’s fall. The judge reasoned that the injury could not reasonably have been avoided. Even if the driver had seen the plaintiff running after the bus, the judge held that he was not obliged to stop. The judge further held that even if the driver had stopped, not stopping was not the cause of the plaintiff’s fall. This reasoning reflects a causation analysis that is not merely formal but practical: the plaintiff’s fall occurred before she reached the front door, and the driver’s conduct did not create the immediate danger that led to the slip.
The judge also considered whether there was any breach of duty. He agreed with defence counsel that the first defendant was not in breach of any duty of care in these circumstances. The judge rejected the plaintiff’s attempt to shift the focus to objective factors such as the plaintiff’s age and what she wanted to do. The judge held that such factors were irrelevant to causation of the injury and did not establish fault on the part of the defendant. In other words, the court treated the negligence inquiry as anchored in the actual mechanism of injury and the reasonable foreseeability and avoidability of harm in the time available.
Finally, the judge addressed the temporal constraints. The accident happened too quickly for the driver to avoid it. The judge noted that there appeared to be no necessity for the driver to say that he looked in the rear view mirror, though he had said he did not only because counsel asked if he did. This aspect of the reasoning reinforces the court’s view that, even if the driver had taken additional steps, the time available would not have allowed him to prevent the injury once the plaintiff began running and fell.
What Was the Outcome?
The High Court dismissed the plaintiff’s claim. The judge held that the plaintiff failed to prove that the first defendant caused her fall and, in any event, that the circumstances did not show negligent responsibility. The dismissal was therefore grounded both in the absence of causation and in the lack of breach of duty as a matter of reasonable avoidability.
As is common in Singapore civil practice, the judge indicated that he would hear the parties on costs at a later date if they could not agree costs. The practical effect of the decision is that the plaintiff did not obtain damages for her injuries, and the defendants were successful on the merits.
Why Does This Case Matter?
Chan Susan v Lai Tet Chong and another is a useful authority for practitioners on how courts approach negligence claims where causation is disputed and where objective evidence (particularly video) is available. The case demonstrates that courts may give decisive weight to contemporaneous recordings that clarify the sequence of events and expose inconsistencies in a claimant’s narrative. For litigators, the decision underscores the importance of aligning pleadings, police reports, and affidavits with the objective record, as later amendments that appear to “embellish” a version of events may undermine credibility.
From a doctrinal perspective, the judgment illustrates the court’s practical approach to causation and avoidability. Even where a claimant alleges that a defendant’s action triggered the injury, the court will examine whether the alleged mechanism is supported by the evidence. Where the claimant’s fall occurs before reaching the relevant point of interaction (here, before reaching the front door), and where the injury results from the claimant’s own misstep while running, the court may find no causal link to the defendant’s conduct. The case also reflects the idea that a duty of care is not absolute in the sense of requiring a defendant to take steps that are impossible or unreasonable within the time available.
For bus operators and drivers, the decision provides reassurance that courts will not automatically infer negligence from a passenger’s attempt to board a moving bus. The court’s reasoning suggests that if the bus has already begun moving after doors are shut and the passenger runs after it, the driver is not necessarily obliged to stop to prevent a fall that occurs too quickly to avoid. For claimants, the case is a cautionary reminder that negligence claims must be supported by credible evidence and that objective proof may defeat allegations of sudden departure or door-related causation.
