As for the scope of O 4 r 8(2), we note that in the usual course of things, a claimant would have validly served an originating process on the defendant, in one way or another, before a Notice of Appointment of Solicitor is filed. Although the parties’ arguments on appeal focused on whether “service” in O 4 r 8(2) referred to both personal and ordinary service or only the latter, there is some merit in the argument that “service of all documents in the action” in O 4 r 8(2) was not intended to apply to the service of an originating process in the first place but to other subsequent documents (eg, pleadings, interlocutory applications, affidavits and written submissions). In particular, the word “action” is defined in O 1 r 3(1) of the ROC as “proceedings commenced by an originating claim or an originating application”. As an originating process is a document that initiates the action itself, it gives rise to an action, rather than being a document arising “in the action”. This reading also seems consistent with the purpose of O 4 r 8 which is to ensure that the status of a party’s legal representation is properly communicated to the court and the other parties, and that any changes in the course of the proceedings are accurately reflected on record in the interest of effective communication and service of documents (Jeffrey Pinsler SC, Singapore Civil Practice (LexisNexis, 2022) (“Singapore Civil Practice”) at para 12-118). Specifically, it appears to us that O 4 r 8(2) provides for a presumption of ongoing representation and a deemed address for service to preserve continuity and avoid any confusion or disruption caused by unnotified changes in a party’s solicitor-client relationship in the midst of the proceedings. In other words, O 4 r 8(2) arguably only contemplates a situation after service of an originating process has been validly effected.
