Third, and most importantly, RegalRare and Kings Luxury have, over multiple occasions, “recognised” the debts demanded of them by Kingsmen (see at [9]–[11] above). The High Court case of The “Banga Borat” [2009] 2 SLR(R) 613 is instructive here. There, the owner of a vessel had, on multiple occasions, repeatedly accepted the validity of a debt owed to the bank, for which he had mortgaged the vessel as security (at [3]–[11]). However, when the bank applied for summary judgment for sale of the arrested vessel as the owner was late with his repayments, the owner belatedly raised defences such as waiver and estoppel (at [20]). Kan Ting Chiu J (as he then was) held that these defences plainly conflicted with the owner’s prior conduct of acknowledging the validity of the debt claimed by the bank. In the words of Kan J (at [21]), “[t]hese representations made to the plaintiff would have raised serious questions over the merits of the defence”, as “[t]he matters on which the defences of waiver and estoppel were based were within the defendant’s knowledge at all times”. While the High Court there was specifically concerned with whether the owner’s prior conduct in court proceedings (ie, the arrest of the vessel) raised a question of res judicata and abuse of process (at [22]–[30]), it nevertheless underscores that, as a matter of common-sense, a court will be slow to entertain a belated dispute against the validity of a debt when the entire course of the debtor’s prior conduct militates to the contrary.
