Summary
Tan Hun Boon v Rui Feng Travel Pte Ltd and another [2017] SGHC 189 is a High Court decision on the assessment of damages for personal injuries arising from a road traffic accident. The court proceeded on the basis that liability was not disputed: interlocutory judgment had been entered by consent at 100% liability in the plaintiff’s favour. The trial therefore focused exclusively on quantum, including the appropriate measure of general damages for pain and suffering (inclusive of loss of amenities) and the assessment of certain future and special damages items.
The plaintiff, who had stopped his car on the shoulder of the Ayer Rajah Expressway to assist a distressed vehicle, was struck after a bus collided with an EMAS truck and then with the plaintiff. The plaintiff suffered multiple fractures to his left leg and hip, ultimately requiring an above-knee amputation. After the amputation, he developed severe phantom limb pain, with significant effects on daily functioning, sleep, concentration, and fatigue. The High Court awarded substantial damages, including a global award of $140,000 for pain and suffering for the injuries to the left leg and hip, and made no separate award for a minor abdominal injury.
What Were the Facts of This Case?
On 23 June 2011, the plaintiff stopped his car along the road shoulder of the Ayer Rajah Expressway (“AYE”) to render assistance to a distressed vehicle. After helping to change a flat tyre, the plaintiff walked back towards his own car, which was parked in front of the distressed vehicle. At that moment, a bus owned by the first defendant and driven by its employee (the second defendant) collided into an EMAS truck that was parked behind the distressed vehicle. The impact caused the EMAS truck to collide into the distressed vehicle, and the distressed vehicle to collide into the plaintiff.
As a result of the collision, the plaintiff sustained multiple fractures on his left leg and a fractured left hip. The injuries were severe enough that the plaintiff ultimately underwent an above-knee amputation. Following the amputation, the plaintiff developed severe phantom limb pain. The judgment records that he required high doses of pain medication to get through the day, but the medication did not eliminate the pain completely. The constant dull pain, together with the effects of pain medication, affected his concentration, caused him to become easily fatigued, and also disrupted his sleep at night.
In the procedural history, the defendants did not dispute liability. Interlocutory judgment was entered by consent on 10 September 2014 at 100% in the plaintiff’s favour, with damages to be assessed. The trial on quantum was heard before Pang Khang Chau JC from 21 to 23 September 2016. The plaintiff claimed damages in the region of $2.2 million, while the defendants maintained that the plaintiff’s entitlement was just over half a million, reflecting a substantial dispute over the appropriate heads of damages and their quantification.
At the commencement of the trial, the parties reached agreement on several items. They agreed on general damages for future medical consultations and pain medication, general damages for future costs of a waterproof prosthesis, and special damages for pre-trial medical expenses. They also agreed on special damages for pre-trial counselling expenses. However, the parties disagreed on several other heads, including pain and suffering (with separate sub-issues such as whether to award separately for abdominal injury), future costs of spinal cord stimulation treatment, future costs of everyday prosthesis, future transport expenses for follow-up treatment, and losses relating to future earnings or earning capacity. The court’s task was to determine which of these claims were supported on the evidence and to quantify them using the established approach to damages assessment in personal injury cases.
What Were the Key Legal Issues?
The principal legal issue was the measure and quantification of damages for personal injuries, particularly the assessment of general damages for pain and suffering (inclusive of loss of amenities). The court had to decide what global figure was appropriate given the nature of the injuries, the surgical interventions, and the plaintiff’s ongoing symptoms—especially the severity of phantom limb pain and its functional and psychological impacts.
A second key issue concerned the approach to quantifying overlapping pain components. The plaintiff argued for a composite approach: an award for the amputation-related pain and suffering, plus a separate additional award for phantom limb pain. The defendants, by contrast, relied on comparable awards and urged the court to avoid double-counting. The court therefore had to determine the correct methodology for incorporating phantom limb pain into the overall general damages assessment.
Third, the court had to assess certain disputed special and future heads of damages, including whether to award separately for minor abdominal injury and whether future treatment costs (notably spinal cord stimulation) were recoverable on the evidence. While the extract provided is truncated after the beginning of the spinal cord stimulation discussion, the judgment’s structure indicates that the court systematically addressed each disputed head, applying principles of causation, necessity, and evidential support in the context of future medical expenditure.
How Did the Court Analyse the Issues?
The court began by identifying the agreed and disputed heads of claim. This matters because damages assessment in Singapore personal injury litigation often proceeds by narrowing the issues: where parties agree on certain items, the court can focus its reasoning on the remaining contested heads. Here, the parties agreed on certain future medical and prosthesis-related expenses and certain pre-trial expenses, leaving the court to decide the contested components of general damages and other disputed special and future damages items.
For pain and suffering, the court analysed the plaintiff’s injuries in two broad groupings: injuries to the left leg leading to the above-knee amputation, and injuries to the left hip/upper left leg. The plaintiff sought separate amounts for the left lower leg injuries and for the left hip/upper left leg injury, and also claimed an additional separate award for abdominal injury. The defendants proposed a global award of $120,000 for the left leg and hip injuries and argued that no separate award should be made for abdominal injury.
In assessing the left leg injuries, the court considered the defendants’ reliance on comparable awards, including Rahman Lutfar v Scanpile Construction Pte Ltd and anor [2016] SGHC 41 and Quek Yen Fei Kenneth v Yeo Chye Huat [2017] SGCA 29. The defendants’ global quantification for the lower-left limb was $80,000, which the court treated as an appropriate starting point. However, the plaintiff argued that the $80,000 figure was inadequate because it did not fully account for the severity of phantom limb pain. The court accepted that the $80,000 award would be inadequate in light of the plaintiff’s severe phantom limb pain.
Crucially, the court rejected the plaintiff’s proposed logic for a composite award that would add a further $30,000 on top of an already severe chronic pain award. The plaintiff relied on Mei Yue Lan Margaret v Raffles City (Pte) Ltd [2005] SGHC 168, where $100,000 was awarded for pain and suffering to a victim who suffered persistent and excruciating pain over several years and underwent multiple surgeries, including spinal cord simulator implantation. The plaintiff submitted that because phantom limb pain was severe, the court should award $100,000 for amputation-related pain and suffering and then add $30,000 for phantom limb pain. The judge held that this would amount to double-counting because the $100,000 in Mei Yue Lan Margaret already took into account severe chronic pain.
Accordingly, the court adopted a more disciplined approach: it used the $80,000 award in Rahman Lutfar as the starting point for the amputation-related injuries and then added an additional amount to account for the severe phantom limb pain. The court fixed the appropriate additional range at $20,000 to $35,000, consistent with the Guidelines for the Assessment of General Damages in Personal Injury Cases (Academy Publishing, 2010), which the parties had referenced. This led the court to conclude that the pain and suffering for the left lower limb injury should range from $100,000 to $115,000.
For the left hip/upper left leg injury, the court accepted the defendants’ approach. The defendants had allowed $18,000 for the hip injury, subject to inflation adjustment at 3% per year from the relevant authority year (Fadhil bin Kassim v Lau Cheong Wai (DC Suit No 1576 of 1995) as referenced in the Guidelines). The court noted that this translated to roughly $25,000 in today’s terms. In addition, the defendants allowed $5,000 for early onset of osteoarthritis, based on Zakaria bin Putra Ali v Low Keng Huat Construction Co (S) Pte Ltd [1993] SGHC 277. The court therefore accepted a total of $30,000 for the left hip/upper left leg injury.
Having determined the appropriate ranges for each injury grouping, the court then applied a global approach. It awarded $140,000 for pain and suffering for the injuries to the left leg and hip. This global figure reflects the court’s balancing of the evidence of functional impairment and ongoing pain, while also ensuring that the damages assessment remained coherent and avoided double-counting of overlapping pain components.
On the abdominal injury, the court took a different approach. The plaintiff had been found to have a small amount of ascites in the peritoneum. The plaintiff accepted that the injury was minor and had resolved without long-term sequelae, but sought $2,000. The defendants argued that it should be taken collectively with the pain and suffering for the other injuries, and thus no separate award should be made (or, at most, a nominal $1,000). The judge agreed with the defendants and made no separate award. This illustrates the court’s practical approach to minor, resolved conditions: where the injury does not produce distinct long-term consequences, a separate award may be unnecessary.
Although the extract ends early in the discussion of future costs of spinal cord stimulation (“SCS”), the judgment’s structure indicates that the court would have proceeded to evaluate whether such future treatment was medically indicated, causally linked to the accident, and supported by credible evidence. In personal injury quantum trials, future medical expenditure is typically assessed on whether the treatment is reasonably necessary and whether the plaintiff has established a sufficient evidential basis for both the need and the cost. The court’s earlier method—identifying agreed items, then scrutinising disputed items with reference to medical evidence and comparable awards—suggests that it would have applied similar principles to the SCS claim.
What Was the Outcome?
The High Court awarded $140,000 for pain and suffering for the injuries to the left leg and hip, using a global approach informed by comparable authorities and the Guidelines. The court also made no separate award for the minor abdominal injury, accepting that it should be subsumed within the overall pain and suffering assessment given its minor nature and resolution without long-term sequelae.
Beyond the extract provided, the judgment would have continued to determine the remaining disputed heads of damages, including future treatment costs and any losses relating to earning capacity. However, based on the reasoning visible in the provided text, the court’s practical effect was to narrow the plaintiff’s recovery to amounts supported by the evidence and to correct the damages methodology by avoiding double-counting of phantom limb pain within already severe chronic pain awards.
Why Does This Case Matter?
Tan Hun Boon v Rui Feng Travel Pte Ltd is significant for practitioners because it demonstrates a careful and structured approach to assessing general damages for pain and suffering in complex amputation cases. The decision highlights that courts will accept that phantom limb pain can justify an upward adjustment from comparable amputation awards, but they will scrutinise the plaintiff’s proposed methodology to ensure that the same pain experience is not counted twice under different labels.
From a precedent and methodology perspective, the case is useful in two ways. First, it confirms the use of comparable awards as starting points, with adjustments based on the severity and nature of the plaintiff’s symptoms. Second, it provides an explicit warning against double-counting where a comparable award already reflects severe chronic pain. This is particularly relevant in cases involving multiple pain syndromes, where medical evidence may describe overlapping mechanisms and where parties may be tempted to “stack” awards for each symptom.
For litigators, the decision also illustrates the importance of evidential precision in future medical claims. Even though the extract does not complete the SCS analysis, the court’s overall approach—separating agreed items from disputed ones, and then assessing each disputed head by reference to medical necessity and credible support—serves as a practical guide for preparing quantum trials. Plaintiffs should ensure that future treatment proposals are supported by medical evidence that links the treatment to the accident-related condition and establishes that the treatment is reasonably necessary, while defendants should focus on causation, necessity, and the risk of double-counting.
