Summary
This High Court decision concerns a work injury compensation claim brought by the next of kin of a deceased employee, Mr Tay Tuan Yong, who died of acute myocardial infarction after suffering chest pains at work and later experiencing cardiac arrest. The Assistant Commissioner (Work Injury Compensation) (“AC”) held that SM Laundry & Linen Pte Ltd (“SM Laundry”) and its insurer, Sompo Insurance Singapore Pte Ltd (“Sompo Insurance”), were liable to compensate the deceased’s family. The applicants appealed against the AC’s finding on liability, while the respondents cross-appealed on the quantum of costs.
The High Court’s analysis focused on the statutory requirement that the employee’s “personal injury by accident” must arise “out of and in the course of employment”. The court examined the factual matrix surrounding the onset of symptoms, the employee’s conduct at the workplace, and the extent to which the employment environment or work-related circumstances could be said to have contributed to the fatal cardiac event. The decision also addressed how the tribunal should approach medical and factual evidence in determining causation within the statutory framework.
What Were the Facts of This Case?
Mr Tay was employed by SM Laundry as a driver from 5 June 2017. On 1 April 2018, he was promoted to operations supervisor. In that role, he was directly answerable to SM Laundry’s CEO, Lim Chuan Aik (“Mr Lim”). The evidence described Mr Lim as having a close working relationship with Mr Tay, referring to him as a “very good friend”. Mr Lim testified that he had agreed to hire Mr Tay initially because Mr Tay had been dismissed by a previous employer and was looking for work. Importantly, Mr Lim also acknowledged that Mr Tay had underlying risk factors that predisposed him to heart attacks.
Mr Tay had a medical history including hyperlipidaemia and hypothyroidism, and he smoked about 20 cigarettes a day. Over the three to four days leading up to the incident, he suffered intermittent episodes of chest pains, breathlessness, and decreased effort tolerance. On the morning of 20 October 2018, at about 7.00am, he experienced the onset of chest pains. Despite feeling unwell, he decided to go to work. He arrived at his workplace at about 9.00am and informed Mr Lim that he was experiencing chest pains. Mr Lim urged him to seek immediate medical attention, but Mr Tay declined.
Mr Tay’s symptoms intensified. He left the workplace at around 10.00am to see a doctor at the Central 24-Hr Clinic at Pasir Ris (“Pasir Ris Clinic”), arriving at 10.54am. An ECG was taken at 11.11am, and he was referred to Changi General Hospital (“CGH”). At CGH, he suffered a cardiac arrest at 12.47pm. He was resuscitated at 12.52pm but died at 1.56pm after suffering a second cardiac arrest. The cause of death was acute myocardial infarction (“AMI”), ie, a heart attack caused by acute obstruction of blood flow to the heart muscle.
At the tribunal stage, the evidence was presented through both factual witnesses and medical experts. Mr Tay’s son, Tay Jia Yi (“TJY”), testified about Mr Tay’s work pattern and overtime. TJY stated that Mr Tay worked Mondays to Saturdays, leaving home at about 6.00am and returning at about 10.00pm, and that he clocked more than 100 hours of overtime each month from October 2017 to October 2018. TJY also said Mr Tay was taking driving lessons to obtain a Class 4 licence for work-related purposes during 17 to 21 September 2018, starting at 8.15am, and that Mr Tay had mentioned he was tired due to long working hours.
Mr Lim testified about Mr Tay’s role as operations supervisor. He described Mr Tay’s duties as supervisory and managerial rather than physically demanding, and he initially suggested that there was little or no mental work involved. However, he later conceded that there was quite a lot of supervisory work given SM Laundry’s two sizeable factories. Mr Lim also testified that he trusted Mr Tay and did not question overtime claims because the company was profitable. Regarding the incident itself, Mr Lim said Mr Tay arrived at about 9.00am, informed him of chest pains, and refused medical attention. Mr Lim’s evidence was that during the hour or so Mr Tay was at the workplace, he was not doing work but was talking to employees about his chest pains. Mr Lim also described a phone call later when Mr Tay was at the clinic, in which Mr Tay asked Mr Lim to handle a work-related delivery mistake and to retrieve the company van.
What Were the Key Legal Issues?
The central legal issue was whether Mr Tay’s death from cardiac arrest constituted an “injury by accident arising out of and in the course of employment” under the Work Injury Compensation Act (Cap 354, 2009 Rev Ed) (“the Act”). This required the court to consider both the “in the course of employment” limb (whether the injury occurred during the employment-related time and circumstances) and the “out of employment” limb (whether the injury was causally connected to the employment). The applicants challenged the AC’s conclusion on liability, arguing that the fatal event was not sufficiently linked to the employment.
A related issue concerned causation and evidential sufficiency. Cardiac events are often multifactorial, and the court had to evaluate how the tribunal should treat pre-existing risk factors, the temporal sequence of symptoms, and any work-related stressors or exertion. The court also had to consider whether the employee’s decision to continue working despite symptoms, and the fact that he left to seek medical attention only later, affected the statutory analysis.
Finally, the respondents’ cross-appeal raised an issue on costs. While the substantive liability question was the primary focus, the court also had to determine whether the AC’s costs award should be adjusted.
How Did the Court Analyse the Issues?
The High Court began by situating the claim within the statutory framework. The incident occurred on 20 October 2018, so the predecessor legislation, the Work Injury Compensation Act (Cap 354, 2009 Rev Ed), governed the claim. The court noted that the Act has since been repealed and re-enacted as the Work Injury Compensation Act 2019 (“WICA 2019”), effective 1 September 2020, but the wording relevant to liability was substantially similar. Section 3(1) of the Act provided that where, in any employment, personal injury by accident arising out of and in the course of employment is caused to an employee, the employer shall be liable to pay compensation in accordance with the Act. The court observed that s 7(1) of WICA 2019 uses similar language, and therefore established principles under the old provision would remain helpful.
The court then addressed the tribunal process and the nature of the dispute. Under the Act, a claimant must notify the Ministry of Manpower (“MOM”), which may issue a Notice of Assessment (“NOA”). If the employer or insurer disputes the claim, it may lodge a Notice of Objection (“NOO”), and the matter is heard by the Commissioner for Labour or an Assistant Commissioner (Work Injury Compensation). In this case, MOM issued an NOA for $204,000, and the applicants lodged an NOO. The AC decided the dispute after two tranches of proceedings, hearing factual witnesses (TJY, Mr Lim, and Dr Lye, the family physician at the Pasir Ris Clinic) and expert cardiology evidence (Dr Baldev Singh and Dr Wong).
On the factual analysis, the court considered the timeline and the workplace circumstances. The undisputed facts showed that Mr Tay experienced chest pains at about 7.00am, informed his supervisor at about 9.00am, refused immediate medical attention despite being urged to do so, and left the workplace at about 10.00am to seek medical care. The court also considered what Mr Tay was doing during the period when he was at work after informing Mr Lim of his symptoms. Mr Lim’s evidence was that Mr Tay was not performing work tasks during that hour but was speaking to other employees about his chest pains. The court treated this as relevant to whether the employment environment contributed to the injury.
In analysing the “arising out of” requirement, the court examined whether the employment could be said to have caused or materially contributed to the cardiac event. The presence of underlying risk factors (hyperlipidaemia, hypothyroidism, and smoking) and the pre-incident symptoms (intermittent chest pains and breathlessness over several days) were significant. The court had to determine whether the employment circumstances—such as work demands, stress, exertion, or other workplace-related factors—were sufficiently connected to the AMI and death, rather than the event being attributable solely to the employee’s pre-existing condition and natural progression.
Although the judgment extract provided is truncated, the overall structure indicates that the court engaged with expert medical evidence and the AC’s reasoning. In work injury compensation cases involving cardiac events, tribunals typically assess whether there was an “accident” in the statutory sense and whether the employment contributed to the injury. The court would have considered medical opinions on causation, including whether the onset of symptoms and the eventual AMI were consistent with a work-related trigger or whether they were more consistent with the natural course of an underlying condition. The court also would have considered whether any work-related stressors were established on the evidence and whether they were properly put to witnesses during cross-examination, as this affects the weight to be given to disputed factual assertions.
On the “in the course of employment” limb, the court considered that Mr Tay was at the workplace when he informed his supervisor of chest pains and later left to seek medical attention. However, being at work is not always determinative of “in the course of employment” for cardiac events; the court still needs to assess whether the injury arose out of the employment and whether the statutory concept of accident is satisfied. The court’s analysis therefore balanced the temporal connection to employment with the causal connection to employment-related circumstances.
What Was the Outcome?
The High Court dismissed or allowed the appeals depending on its assessment of the AC’s liability finding and the costs issue. Based on the AC’s order described in the extract, the practical effect at tribunal level was that SM Laundry and Sompo Insurance were ordered to pay the next of kin $204,000 in compensation and $5,000 in costs. The High Court’s decision determined whether that liability and compensation regime would stand or be overturned, and whether the costs award would be varied following the respondents’ cross-appeal.
In practical terms, the outcome affects not only the immediate compensation payable to the family but also the approach employers and insurers should take when disputing cardiac death claims under the Act, particularly where the employee has pre-existing risk factors and symptoms precede the workplace incident.
Why Does This Case Matter?
This case is significant for practitioners because it illustrates how Singapore courts evaluate work injury compensation claims involving sudden medical events, especially cardiac deaths. The decision underscores that liability under the Work Injury Compensation Act requires more than the mere fact that the employee died while at work. The statutory test demands a connection between the employment and the injury, assessed through both factual circumstances and medical causation evidence.
For employers and insurers, the case highlights the importance of evidential discipline. Where the employer disputes that the work environment contributed to the injury, it must engage with the factual timeline, the employee’s duties at the material time, and the credibility and completeness of witness testimony. The court’s attention to what was (and was not) put to witnesses during cross-examination can be decisive in determining which factual narratives are accepted.
For claimants, the case demonstrates the need to establish a coherent causal link between employment and the injury. Where there are pre-existing conditions and symptoms preceding the incident, claimants must still show that the employment circumstances were sufficiently connected to the injury “arising out of and in the course of employment”. The decision therefore serves as a guide for structuring evidence, including medical expert reports, to address both limbs of the statutory test.
