However, the circumstances or the facts do not warrant it in the present scenario. In fact, we are guided by the Singapore Court of Appeal case of Fustar Chemicals Ltd (Hong Kong) v Liquidator of Fustar Chemicals Pte Ltd [2009] 4 SLR 458, at pp. 468-469 [ABOA, Tab 5] which held as follows: “Although a liquidator “is not bound to admit” any proof of debt which, if admitted, would affect the interests of creditors and contributories, he is only bound to take extraordinary steps to scrutinize a proof of debt on the basis that it could be a false claim in cases where he has reason to be suspicious about its genuineness or legal validity. Factors to be considered include, inter alia, the origins of the debt, the length of 23 time the debt has been due, how the company has treated the debt in its financial statements, the business of the debtor company and, where relevant, the relationships between the claimants and the controlling shareholders of the company. In assessing these factors, the liquidator must rely on: (a) knowledge of the general principles of company accounting; (b) the auditing practice of companies by independent auditors; (c) the effect and implication of directors’ and shareholders’ approvals annually of company accounts made in compliance with the law; (d) the customary insolvency practice in verifying debts; and (e) some degree of common sense in understanding human relationships. In taking into account these matters, he should also apprise himself of the nature of the business of the company, and other facts peculiar to the company in liquidation. In the case of the present company, the relationship between the directors and the shareholders, inter se, is obviously a relevant factor to be considered. [21] Therefore, although a liquidator has a duty to scrutinize all proofs of debt, the level of scrutiny required by the liquidator to discharge this duty must, in the final analysis, depend on the circumstances of the case. In the present case, OSH rejected FCL’s proof only because it could not produce the related primary documents, even though FCL had explained that they had been destroyed or lost due to effluxion of time. This was not an unbelievable reason since the claimed debt was originally acknowledged by the 24 Company as far back as January 1995, more than 9 years before the Company was wound up. OSH was aware that under Hong Kong law, FCL was not obliged to preserve indefinitely the related documents concerning a debt due to the Company (which is, in any case, from a related company or at least part of a group of companies controlled by NCL and his family). OSH was also aware that FCL’s proof of debt was a debt that the Company itself had consistently acknowledged as owing in its own annual accounts, which had been approved by the WSW qua director and shareholder. In our view, although a liquidator has the power to look behind the audited financial statements and audit confirmations, a creditor’s proof of debt should not be lightly rejected if the debt has been consistently acknowledged in audited accounts and or through audit confirmation statements. Such acknowledgments amount to an admission of the debt. Furthermore, a long effluxion of time inevitably creates evidential difficulties, as in the present case. Witnesses may be difficult to locate or may not be able to recollect essential details, and some may even become uncooperative. The relevant primary documents can also be destroyed or lost through the passage of time. In essence, while we accept that the burden of proof ordinarily rests on the creditor to substantiate a proof of debt this does not mean that the only means by which a creditor can prove a proof of debt must be through the production of primary documents.”
