I reject the Plaintiff’s argument on duress. Substantive requirements aside, this defence was not clearly pleaded by the Plaintiff. MPH Rubin J observed in the High Court decision of Lee Kuan Yew v Chee Soon Juan [2003] 3 SLR(R) 8 that the defence of duress had to be specifically and carefully pleaded. This was certainly not done by the Plaintiff – the material fact of duress was merely alluded to in one line in its Reply. Phillip Pillai J also rejected a suggested defence of economic duress on the basis that it was not pleaded in Lim Chin San Contractors Pte Ltd v Shiok Kim Seng (trading as IKO Precision Toolings) [2011] 1 SLR 433. However, the lack of specific pleading is not the main ground on which I reject the Plaintiff’s argument on duress. On the evidence presented before me, I am not convinced that the Plaintiff had proved the fact of duress. Economic duress has been acknowledged as a separate and distinct vitiating factor that could render a contract voidable (see E C Investment Holding Pte Ltd v Ridout Residence Pte Ltd and another (Orion Oil Ltd and another, interveners) [2011] 2 SLR 232 at [46]) but it must also be noted that the doctrine will be applied only in exceptional situations (see Andrew Phang Boon Leong, The Law of Contract in Singapore (Academy Publishing, 2012) at para 12.020). It has to be shown that there was illegitimate pressure applied by one party, and that it was a but-for reason for the person entering into the contract (see Sharon Global Solutions Pte Ltd v LG International (Singapore) Pte Ltd [2001] 2 SLR(R) 233 in general). The burden is on the party raising it to show that the duress put him in a position where he was compelled to accede to the demand. The threshold for using duress as a defence to a contract is high, and fact-specific, and I am not convinced that the Plaintiff had met it. All we have is Monsur’s bare claim in his AEIC that he was threatened. While Monsur said he regretted signing the June 2011 Minute, he only sent the first email of apparent protest in 22 September 2011, three full months after he signed it. Even then, this email of 22 September 2011 did not mention anything regarding the June 2011 Minute nor were there allegations of duress; it only beseeched Ng Chee Hwa of the Defendant to follow the 2008 agreement, and there was no mention of anything in June 2011. The only inference that could be drawn from that was that Monsur had regretted signing the June 2011 Minute. In the subsequent email exchanges between the parties, there was also no mention of Monsur being coerced in June 2011. I accept that the emails evidenced some kind of disagreement between them, but that is not sufficient to show duress. Disagreement among business partners is not uncommon. Even if threats were made, it was not evident that they sufficiently overborne his will and alone caused Monsur to make the agreement. Monsur had not made much reference to the potentially adverse effects of not agreeing, other than there would be financial consequences in Bangladesh. It is unclear if the Plaintiff would be able to have their workers registered with other companies than with the Defendant, i.e., that the Plaintiff had no alternative but to accede to the Defendant’s demand. The evidence is insufficient to conclude either way. In any case, the Plaintiff appeared to have acquiesced and performed the part of the agreement that required the Plaintiff to pay to the Defendant’s CCTC $600 per worker that passed the test, from the invoices addressed to the Plaintiff, with markings showing “39 x $600” and the description being fees for April 2011 Test. There does not appear to be contemporaneous protest against the invoices, and the first email suggesting so was only on 24 November 2011. Monsur was unable to give an account of the right sums that should have been invoiced to him either, in response to my questioning:
