Summary
Tan Teck Boon v Lee Gim Siong and others ([2011] SGHC 76) is a High Court decision on the assessment of damages for personal injuries arising from a road traffic accident. The plaintiff, Tan Teck Boon, was injured when the 1st defendant’s car crossed the centre of the road and collided with his vehicle, and the 2nd defendant’s lorry subsequently collided with the rear of the plaintiff’s car. Liability had already been determined by consent at an interlocutory stage, with damages to be assessed on the basis that the 1st defendant bore 90% responsibility and the 2nd and 3rd defendants together bore 10%.
The central dispute at the assessment stage concerned the extent of the plaintiff’s recovery and the impact of his injuries on his ability to work. The court accepted that the plaintiff had suffered serious injuries, including a closed fracture of the right femur requiring multiple surgeries due to implant failure and delayed union, a closed fracture of the right ulna, and a closed fracture of the left distal radius. However, the court was not persuaded by some aspects of the plaintiff’s account of prolonged disability, and it preferred the evidence of the treating physician, Dr David Paul Bell, over other expert testimony that the court considered to be less reliable or extreme in parts.
Ultimately, the court awarded damages for pain and suffering at a figure it considered appropriate in light of comparable authorities and the medical evidence. It also addressed disputed special damages and rejected or reduced certain heads of claim where the risk of future complications (such as osteoarthritis) was not adequately proved. The decision illustrates how Singapore courts calibrate awards by reconciling medical findings, credibility assessments, and precedents, particularly where the plaintiff’s functional narrative is contested.
What Were the Facts of This Case?
On 26 December 2006, the plaintiff’s vehicle was involved in a two-stage collision. The 1st defendant’s car, travelling in the opposite direction, crossed the centre of the road and collided with the front and right side of the plaintiff’s car. After that initial impact, the 2nd defendant’s lorry, travelling behind the plaintiff’s car, collided into the rear of the plaintiff’s vehicle. The plaintiff sued for injuries arising from these collisions.
The injuries were significant and involved multiple fractures. The plaintiff’s treating doctor, Dr David Paul Bell, prepared a medical report dated 27 March 2009. The report recorded that the plaintiff was admitted to Changi General Hospital and underwent surgical fixation for: (1) a closed fracture of the shaft of the right femur; (2) a closed fracture of the right ulna; and (3) a closed fracture of the left distal radius. The plaintiff was discharged on 3 January 2007, but complications arose in relation to the right femur, leading to two further surgeries for revision of fixation and bone grafting on 22 February 2007 and 3 October 2007.
As a result of the surgeries, the plaintiff had multiple scars on his right forearm, left wrist, both hips, and the right knee cap. He also had residual pain in his right groin (described interchangeably as the right inner thigh) and in his left wrist. The plaintiff’s right leg was shortened by 1 cm. He was granted continuous hospitalisation leave from 26 December 2006 to 14 September 2010. These medical facts were not disputed; the disagreement lay in how well the plaintiff recovered and what functional limitations persisted.
Before the accident, the plaintiff was a sole proprietor of Tom Express, a courier business. Under a “DHL Owner Operator Agreement”, Tom Express provided express transportation services for DHL Express (Singapore) Pte Ltd over specified routes. The plaintiff personally carried out courier assignments in the Changi South Lane and Bedok North areas, and he paid another individual, Ahmadkalil Bin Mohamed, to carry out assignments in the Tampines Central area from September 2005. After the accident, the plaintiff claimed that he could no longer personally perform courier work and had to subcontract assignments to others, including Neo Say Seong and a company, i.Supplies, when Neo was unavailable. The defendants, by contrast, challenged the reliability of the plaintiff’s evidence and argued that he could return to courier work with only limited assistance for heavy loads.
What Were the Key Legal Issues?
The principal legal issue was the assessment of damages following interlocutory judgment. While liability apportionment was agreed (90% against the 1st defendant and 10% against the 2nd and 3rd defendants), the court still had to determine the appropriate quantum of damages for pain and suffering and for any other heads of loss that were disputed. This required the court to evaluate the credibility of the plaintiff’s account of disability and to weigh competing expert medical opinions.
A second issue concerned the proof of future risks and their monetary valuation. The plaintiff sought additional sums for the risk of osteoarthritis in the right hip and knee (for the femur injury) and in the left wrist (for the distal radius injury). The court had to decide whether such risks were adequately supported by the medical evidence and whether they were sufficiently probable to justify separate awards.
Third, the court had to address special damages and disputed factual claims. Although the parties agreed on two items of special damages—medical expenses of $8,203.00 and transport expenses of $1,911.30—other claims were disputed. The court’s approach to these disputes reflects a broader principle in personal injury litigation: damages must be grounded in evidence rather than asserted estimates, and the plaintiff bears the burden of proving the loss claimed.
How Did the Court Analyse the Issues?
The court began by setting out the procedural and factual context and then turned to credibility. Although the medical facts of the fractures and surgeries were not disputed, the defendants attacked the plaintiff’s reliability as a witness. The defendants argued that the plaintiff and his father were unreliable, citing admissions during cross-examination about claiming tax relief without basis and making false statements to the CPF Board such that CPF payments were made for no work. The defendants also pointed to gaps in recollection in the father’s affidavit evidence and to the lack of documentary support for certain claims, including the period the plaintiff said he was wheelchair-bound and the amounts he paid subcontractors.
In assessing evidence, the court indicated that it generally agreed with the defendants that the plaintiff’s evidence did not appear reliable in a number of respects. This credibility assessment mattered because the plaintiff’s claimed functional limitations—such as being unable to care for himself and being wheelchair-bound until August 2008—were contested. The court also evaluated the expert witnesses. It found Dr Bell’s expert testimony to be the most reliable, noting that Dr Bell was the treating physician and had prolonged contact with the plaintiff, which gave Dr Bell familiarity with the plaintiff’s condition. By contrast, the court considered that Dr Yip and Dr Chang took positions that were “rather extreme” on certain matters under cross-examination.
On pain and suffering, the court approached the valuation by considering each injury in turn and comparing the injuries and recovery to relevant authorities. The plaintiff claimed $84,000 for pain and suffering, while the defendants argued that the appropriate award should be $38,000. The court concluded that $55,000 was suitable overall and then allocated amounts to each injury head.
For the closed fracture of the shaft of the right femur, the plaintiff sought $30,000, citing implant failure, delayed union, multiple surgeries, difficult recovery, 1 cm leg shortening, and residual pain. The defendants argued for $17,000–$19,000, contending that objective evidence did not support the plaintiff’s account of being wheelchair-bound until August 2008 and that the 1 cm shortening did not cause permanent functional impairment. The court awarded $25,000. It reasoned that while the 1 cm shortening per se might not leave the plaintiff with functional impairment, the injury as a whole was serious and resulted in slow and complicated healing. The court emphasised that implant failure and delayed union required two further surgeries. It also accepted evidence of residual pain in the right groin/inner thigh, aggravated by prolonged standing, walking on uneven ground, and getting into and out of the driver’s seat, and it noted that the plaintiff walked with a limping gait. This shows the court’s method: it did not treat the leg shortening as the sole determinant, but considered the overall injury trajectory and residual symptoms.
The court also dealt with the plaintiff’s attempt to obtain a separate sum for the risk of osteoarthritis in the right hip and knee. It rejected this head because the risk was not adequately proved. Dr Bell had not mentioned osteoarthritis risk in the right hip and knee; instead, Dr Bell had referred to osteoarthritis risk in the left wrist where the fracture had occurred at a joint. Dr Chang also opined that a mid-shaft fracture that had healed and resulted only in 1 cm shortening would not lead to a risk of osteoarthritis. The court therefore preferred the evidence of Dr Bell and Dr Chang and declined to award a separate amount for osteoarthritis risk in that region.
For the closed fracture of the right ulna, the plaintiff claimed $15,000, relying on Dr Yip’s view that the fracture had malunited and on X-ray evidence. The defendants argued for $10,000, pointing to Dr Chang’s opinion that the fracture had united without complication and that the plaintiff had recovered full function of his right forearm. The court awarded $10,000. It accepted Dr Bell and Dr Chang’s evidence that the fracture healed without complication and that the plaintiff had normal flexibility in his right forearm. The court nevertheless accounted for remaining weakness in gripping and holding heavy objects. This illustrates that even where the court accepted that the fracture healed, it still considered residual functional effects in calibrating the award.
For the closed fracture of the left distal radius, the plaintiff claimed $12,000 for continued weakness and difficulty carrying and moving heavy objects, and an additional $5,000 for osteoarthritis risk in the left wrist. The defendants argued for $10,000 and contended that Dr Bell’s “moderate risk” assessment should be treated as a probability of 10–20%. The court’s reasoning, as far as the extract shows, indicates that it was prepared to award a figure reflecting both the injury’s impact and the evidential strength of the osteoarthritis risk. The truncated portion of the judgment prevents full reproduction of the court’s final arithmetic for this head, but the extract clearly demonstrates the court’s evidential approach: it required medical support for future risk and used expert probability characterisations to decide whether separate awards were justified.
What Was the Outcome?
The court awarded damages for pain and suffering in a total amount it considered appropriate, arriving at $55,000 as the suitable figure for that head. It then allocated specific amounts to each injury: $25,000 for the right femur fracture, $10,000 for the right ulna fracture, and an amount for the left distal radius fracture (with the court’s treatment of the osteoarthritis risk head depending on the strength of the medical evidence). The court’s overall approach reflects a balancing exercise between the seriousness of the injuries, the medical evidence of residual symptoms, and the credibility of the plaintiff’s claimed functional limitations.
In addition, the court accepted the agreed special damages for medical expenses and transport expenses ($8,203.00 and $1,911.30 respectively). It rejected or reduced disputed claims where the evidence was insufficient, including the plaintiff’s claims for osteoarthritis risk in the right hip and knee due to inadequate proof. The practical effect is that the plaintiff’s recovery was recognised as substantial, but the quantum was moderated to reflect evidential reliability and medical causation/probability.
Why Does This Case Matter?
Tan Teck Boon v Lee Gim Siong is instructive for practitioners because it demonstrates how Singapore courts assess damages where liability is settled but quantum remains contested. The decision highlights that credibility and evidential support remain crucial even when the medical diagnosis and surgeries are not disputed. Where a plaintiff’s narrative of disability is challenged, the court may accept the medical baseline but reduce awards to align with what the evidence can substantiate.
The case is also useful for understanding the evidential threshold for future risks. The court’s refusal to award a separate sum for osteoarthritis risk in the right hip and knee underscores that speculative or insufficiently supported risks will not automatically translate into additional damages. Practitioners should therefore ensure that expert evidence clearly links future complications to the injury and provides a defensible probability assessment, rather than relying on general statements.
Finally, the decision provides a practical template for how to use comparable authorities in personal injury assessments. The court explicitly compared the plaintiff’s femur injury to earlier decisions such as Loh Chee Wang v Ong Leong Chye (DC Suit No. 4300 of 2003) and Chiam Kim Loke v Lee Wing Hoong ([2004] SGHC 37), adjusting the award based on differences in severity, recovery complexity, and residual deformity or disability. This comparative method is central to consistent and principled damages assessment in Singapore.
