Y is considered to have waived Y's right to raise the PO.I rely on the following judgment of Low Hop Bing J (as he then was) in the HC case of Malaysia Building Society Bhd "Preliminary Objections It is to be noted that in the six or more affidavits filed by the defendant to resist the plaintiff's application herein, the defendant did not advert to any preliminary objection, nor give the plaintiff any notice of the defendant's intention to raise preliminary objections, which only surface now in the submissions presented for the defendant, thereby springing surprises on the plaintiff. In such a situation, part H, para. 19(a), (b) and (c) of the Bar Council Rulings 1997 requires that a written notice be given. ... Apart from the aforesaid ruling, our courts have consistently upheld such procedure ie, in giving the other side notice at the earliest moment: per Thomson, CJ in Gurbachan Singh v. Seagrott & Campbell (No. 2) [1962] 28 MLJ 370; per Edgar Joseph Jr, J (later FCJ) in Jasabena Sdn. Bhd. v. Beh Heng Poo & Anor. [1985] 1 MLJ 394; per Abdul Kadir Sulaiman J (now JCA) in Datuk Bandar Kuala Lumpur v. Seman bin Amat & 2 Other Cases [1996] 3 CLJ 263. In Bukit Melita Sdn Bhd v. Lam Geok Hee & 7 Ors [1997] 4 AMR 3160, one of the issues for determination revolves around the effect of the failure by the respondent's solicitor to give written notice of the preliminary objection to the appellant's solicitors. There I held as follows: In my considered view, it is trite law that a party who wishes to raise any preliminary objection must give written notice to the other party's solicitors as early as possible of his intention to do so. Failure to do so would amount to a waiver of the party's right to raise the objection: per Mohd Hishamudin bin Mohd Yunus JC (as he then was) in Public Bank Berhad v. Berjaya Housing Development Sdn Bhd & Ors [1995] 1 CLJ 237, and Edgar Joseph in Jasabena Sdn Bhd v. Beh Heng Poo & Anor [1985] 1 MLJ 394. It was held in these two cases that the notice of preliminary objections must satisfy two requirements, viz: (a) the notice must be in writing; and (b) the notice should be given at the earliest possible moment to the other side who otherwise might be taken by surprise. It is obvious that the whole purpose of the notice is to promote good etiquette amongst members of the Bar and more importantly to remove the element of surprise. It is necessary that the party against whom an objection is intended to be raised should not be taken by surprise and that both parties are given equal opportunities to prepare their submissions in order to ventilate all the relevant issues; being forewarned is being forearmed. Although it is true to say that the element of surprise in the instant case is completely non-existent since the parties herein are given adequate equal opportunity and time to prepare their respective written submissions, it must be immediately emphasized that the notice of objection must at all times be given to the other side. There can be no excuse for any delay, intentional or otherwise, in giving notice to the appellant. Since the respondents' learned counsel has failed to give any prior written notice of the preliminary objection, I hold that the respondents are deemed to have waived their rights to do so. Waiver implies something in the nature of estoppel (See Wong Chor San v. Chop Yee Kuan [1975] 23 MLJ 68 at p. 70). On the aforesaid authorities, I would have thought that it would have been adequate to dismiss the preliminary objections raised by the defendant's learned counsel." (emphasis added).
