Of the four factors, the emphasis, in the first instance at least, is on the first two (ie, the length of the delay and the reasons for the delay) (Lee Hsien Loong v Singapore Democratic Party [2008] 1 SLR(R) 757 (“Lee Hsien Loong”) at [19]). The last two factors, on the other hand, have been described as being “qualifying factors, the fulfilment of which [are] essential to enable the court to exercise its discretion” (AD v AE [2004] 2 SLR(R) 505 (“AD”) at [13]). On the whole, the application should be on grounds “sufficient to persuade the court to show sympathy” to the applicant (Pearson at [20], quoted in Linda Lai at [45]). Moreover, when applying the abovementioned factors, the overriding considerations are that the ROC must prima facie be obeyed with reasonable diligence being exercised (Linda Lai at [45], citing Thamboo Ratnam v Thamboo Cumarasamy [1965] 1 WLR 8 at 12), and that there should be finality (Linda Lai at [45], citing The Melati [2004] 4 SLR(R) 7 at [37]).
