The observations on extension of time in Sun Tian Gang, which the appellants relied on, were, strictly speaking, made obiter. The question before that court was whether the Notice of Arbitration and the Award had properly been served on the defendant, who sought to set aside the Award. On the defendant’s case, he had only received the Award in May 2015, although the proceedings to set aside the Award would, even on his case, have been commenced out of time as they were only brought on 16 October 2015. However, the court went further to find that the forwarding of the Award to the defendant in May 2015 could not have “the effect of [the defendant] being deemed to have received the Award and the Reasons” (Sun Tian Gang at [78]), and therefore that the three month time limitation period under Art 34(3) did not begin to run (Sun Tian Gang at [81]). It was in the context of this finding that the court went on to consider whether, in any event, the period of three months provided in Art 34(3) could be extended. The court reasoned that (a) the time limit in Art 34(3) was a procedural one and that the court had jurisdiction and discretion to extend such time; (b) the Singaporean case law could be distinguished on the basis that the time limit was “mandatory by way of the applicable domestic rules [namely, the Rules of Court]”; and (c) that the phrase “may not” should be read permissively, in line with the permissive nature of the word “may” in Art 34(2). In contrast, the decision in BXS v BXT which the Judge followed in the present case was that it would be inappropriate to reason from the word “may” in Art 34(2) in interpreting the phrase “may not”. Further, it would be incorrect to say that the Rules of Court render the time limit mandatory and the basis on which the court in Sun Tian Gang sought to distinguish Singaporean case law is therefore unpersuasive.
