Summary
This High Court decision concerns two practical issues arising after an earlier damages judgment in a patent-related dispute: (i) the correct commencement and end dates for pre-judgment interest, and (ii) the appropriate costs consequences of offers to settle made under O 22A of the Rules of Court (ROC). The court, Tay Yong Kwang JA, was required to clarify how the parties’ competing Offers to Settle (“OTS”) affected both interest and costs, particularly where the action had been bifurcated and where a “Joint OTS” was later withdrawn.
On interest, the court accepted that pre-judgment interest should not run until the defendant received notice of the plaintiff’s election of remedy. In a bifurcated structure, liability and remedies were dealt with at different stages; accordingly, the commencement date for interest was fixed at 16 July 2008, when the plaintiff gave notice of its election. The end date for UOB’s interest was tied to the interim payment date (2 February 2010). For FCC, while the same commencement date applied, the court limited the interest period to a date linked to the Joint OTS’s validity window, reasoning that it would be unfair to run interest to the later damages judgment date given the plaintiff’s refusal to accept the Joint OTS.
On costs, the court applied the O 22A framework and exercised discretion in allocating costs between the plaintiff and the defendants. The decision reflects a careful balancing of (a) the statutory costs consequences where an OTS is not accepted and the plaintiff fails to obtain a more favourable judgment, and (b) fairness considerations where multiple defendants, bifurcation, and partial success complicate the attribution of costs.
What Were the Facts of This Case?
The dispute between Main-line Corporation and the defendants arose out of patent infringement proceedings. The matter had already proceeded to a “judgment on damages” delivered by Tay Yong Kwang JA in Main-line Corporation v United Overseas Bank and another [2016] SGHC 285. That earlier judgment determined the assessment of damages and directed the parties to file written submissions on the appropriate interest and costs orders. The present decision is therefore not a re-trial of liability or quantum; it is a post-assessment clarification and determination of interest and costs.
A key feature of the litigation was bifurcation. The court dealt with “liability” and “remedies” at different stages. This bifurcation mattered because pre-judgment interest depends on when the defendant becomes aware that it must pay the relevant monetary remedy. The court accepted that until the defendant received notice of the plaintiff’s election of remedy, it was unclear how the defendant would have to compute and pay the sum ultimately ordered. This is why the commencement date for interest was contested.
In addition, the parties made multiple Offers to Settle (“OTS”) under O 22A of the ROC. The extract shows three OTS served on the plaintiff: one by UOB dated 5 December 2012, one by FCC dated 6 December 2012, and two OTS dated 27 May 2016 (one from UOB and one from FCC) described as the “Joint OTS”. The Joint OTS was structured so that the plaintiff could not accept one without also accepting the other; it was therefore a package offer. The Joint OTS was later withdrawn on 27 October 2016 by both UOB and FCC.
Finally, the financial timeline included an interim payment. For UOB, there was an interim payment of S$1,962,424.30, and the court treated the sending of the cheque (enclosed in a letter from UOB’s solicitors) on 2 February 2010 as the point at which the interest period should end for UOB. For FCC, the judgment sum awarded was S$4,795,000.00. The plaintiff sought pre-judgment interest at an undisputed rate of 5.33% per annum, but the parties disagreed on when interest should start and when it should stop.
What Were the Key Legal Issues?
The first legal issue was the commencement and termination of pre-judgment interest against each defendant. The plaintiff argued for a general accrual-based approach: interest should start when the loss accrued (for UOB, 10 May 2002; for FCC, 11 October 2001, linked to the date of the material event used as a reference point in the damages assessment). In the alternative, the plaintiff suggested that interest should start no later than 5 October 2004, the date the action commenced. The defendants, however, argued that interest should not run until they received notice of the claim that they had to meet—particularly the plaintiff’s notice of election of remedy.
The second legal issue concerned the interaction between O 22A offers to settle and the court’s orders on costs and, indirectly, the fairness of interest periods. UOB relied on its OTS of 5 December 2012 and argued that, under O 22A r 9(3), it should receive indemnity costs from 5 December 2012 onwards because the plaintiff did not obtain a more favourable judgment than the terms of the OTS. FCC argued that the Joint OTS should be taken into account even though it was withdrawn, and that the plaintiff’s refusal to accept it should affect both costs and the fairness of interest calculations.
A further issue—tied to costs—was attribution. Where the plaintiff succeeded against one defendant (FCC) but failed or succeeded less against another (UOB), the court had to decide how to allocate costs between the defendants and the plaintiff. The extract indicates competing submissions on how much of the plaintiff’s costs were attributable to the claim against FCC, and whether the plaintiff substantially succeeded against FCC given that the damages awarded were less than what was claimed.
How Did the Court Analyse the Issues?
On pre-judgment interest, the court’s reasoning turned on the bifurcated nature of the proceedings and the principle that a defendant should not be liable to pay interest until it has notice of the claim that it must meet. Tay Yong Kwang JA accepted UOB’s position that interest should commence when UOB received the plaintiff’s notice of election of remedy, which in this case was 16 July 2008. The court explained that because liability and remedies were dealt with at different stages, it was unclear to UOB how it would have to compute the amount payable until the plaintiff elected the relevant remedy. This uncertainty justified delaying the start of interest.
The court also determined the end date for UOB’s interest by reference to the interim payment. It accepted that the interest period should end on the date when the cheque for the interim payment was sent to the plaintiff. The court treated 2 February 2010 as the relevant date because UOB’s solicitors wrote to the plaintiff’s solicitors enclosing the cheque for the interim payment. Importantly, the court noted that the final judgment amount awarded against UOB did not exceed the interim payment amount, reinforcing why interest should not continue beyond the interim payment date.
For FCC, the court applied the same commencement logic: the date of commencement of pre-judgment interest was also fixed at 16 July 2008. The court rejected FCC’s argument that the plaintiff should receive only a reduced portion of interest because of the plaintiff’s alleged dilatory conduct. The court referred to its earlier finding in the damages judgment that the parties were equally responsible for the delay in the conduct of the assessment hearing. That finding undermined FCC’s attempt to reduce interest by attributing delay solely to the plaintiff.
However, the court did adjust the end date for FCC’s interest on fairness grounds. While the plaintiff sought interest running until the damages judgment date (29 December 2016), the court considered it unfair to FCC to order interest to run that long. The court’s fairness analysis was anchored in the plaintiff’s refusal to accept the Joint OTS in 2016. The Joint OTS had remained open for acceptance for a 14-day period under O 22A r 3(1) of the ROC. Accordingly, the court ordered that interest in FCC’s case accrue at 5.33% per annum on the S$4.795m judgment sum from 16 July 2008 to 10 June 2016 (being the end of the 14-day acceptance window). This approach effectively “stopped the clock” at the point when the plaintiff had declined an offer that, if accepted, would have placed it in a better position than the eventual court award.
On costs, the court began by identifying the statutory framework. Under O 22A r 9(3) of the ROC, where a defendant makes an offer to settle that is not withdrawn and has not expired before disposal of the claim, and the plaintiff does not accept it and fails to obtain a more favourable judgment, the plaintiff is generally entitled to costs only on the standard basis up to the date the offer was served, while the defendant is entitled to indemnity costs thereafter. The extract indicates that the court treated this as the governing principle for the costs consequences of UOB’s OTS.
UOB’s position was that it should receive standard basis costs up to 2 February 2010 (the interim payment date) and indemnity costs from 5 December 2012 onwards, relying on the fact that its OTS did not stipulate a time for acceptance and was not withdrawn. The court also considered FCC’s arguments that there should be no order as to costs between the plaintiff and FCC, or at least that only a small fraction of the plaintiff’s costs were attributable to the claim against FCC. FCC emphasised that the damages finally awarded were much less than what the plaintiff claimed and argued that the plaintiff could not be said to have substantially succeeded.
Although the extract truncates the remainder of the costs analysis, the visible reasoning shows that the court was attentive to the complexity of the case and the need to align costs orders with the parties’ relative success and conduct. The court also noted that the costs orders would relate to the period starting on 31 October 2007, the date of the Court of Appeal’s judgment in First Currency Choice Pte Ltd v Main-Line Corporate Holdings Ltd and another appeal [2008] 1 SLR(R) 335. This indicates that the court’s discretion on costs was exercised within a defined temporal scope, consistent with the procedural history.
What Was the Outcome?
On interest, the court ordered UOB to pay pre-judgment interest at 5.33% per annum on the interim payment amount of S$1,962,424.30 from 16 July 2008 to 2 February 2010. The court accepted UOB’s calculation of the interest sum as S$162,483.89. For FCC, the court ordered pre-judgment interest at 5.33% per annum on the judgment sum of S$4.795m from 16 July 2008 to 10 June 2016, thereby limiting the interest period by reference to the Joint OTS acceptance window.
On costs, the court applied O 22A r 9(3) and addressed the parties’ competing submissions on standard versus indemnity costs and on attribution between defendants. While the extract does not include the final operative costs orders, the decision clearly reflects that the court treated the OTS regime as central to determining costs consequences and used fairness considerations to prevent a party from benefiting from its refusal to accept an offer that would have improved its position.
Why Does This Case Matter?
Main-line Corporation v United Overseas Bank Ltd and another [2017] SGHC 27 is a useful authority for practitioners dealing with (i) pre-judgment interest in bifurcated proceedings and (ii) the practical effects of O 22A offers to settle on both interest and costs. The decision reinforces that the commencement of pre-judgment interest may depend on when the defendant receives notice of the plaintiff’s election of remedy, rather than on an abstract “accrual of loss” date, especially where remedies are determined at a later stage.
For costs, the case illustrates how the OTS framework can produce indemnity costs consequences where the plaintiff fails to beat the offer. It also demonstrates that courts may consider the fairness implications of an offer’s structure and timing, including the effect of a Joint OTS that was not accepted and was subsequently withdrawn. Even where an OTS is withdrawn, the court may still treat the offer’s existence and the plaintiff’s refusal as relevant to limiting exposure—particularly in the context of interest.
Practically, the decision encourages careful drafting and strategic use of OTS instruments. Parties should consider whether an OTS is structured as a package (as with the Joint OTS), whether it is withdrawn, and how long it remains open for acceptance. For plaintiffs, the case underscores the risk that refusing a well-judged OTS may reduce recoverable interest and shift costs outcomes. For defendants, it highlights the value of making offers that are not withdrawn and that are capable of being compared meaningfully against the eventual judgment.
