(e) The Respondents point out that the Petitioner waited nearly two years after the filing of his petition and attended multiple court hearings before raising this objection on the eve of the trial, suggesting the application is a tactical strategy to delay proceedings. This Court's Assessment [7] Based on the facts and the applicable legal principles, KDI and IK should not be recused. The Petitioner's application in Enclosure 101 is legally unsustainable and is hereby dismissed for the reasons analyzed and iterated below. [8] Malaysian law requires the moving party like the Petitioner to establish three limbs for disqualification: a threshold relationship, possession of relevant confidential information, and a strong case. Here there is no threshold relationship. The Petitioner was never a client of KDI; he is a stranger to the firm's relationship with the $ 1^{\mathrm{st}} $ Respondent. The Court of Appeal's decision in Mirza Mohamed Tariq Beg bin Mirza HH Beg v Margaret Low Saw Lui & Ors [2009] 4 MLJ 671; [2009] 4 CLJ 303 establishes that the doctrine of confidentiality does not apply if there is no solicitor-client or fiduciary relationship between the moving party and the counsel sought to be disqualified. This authority is binding on this Court and Enclosure 101. [9] See also Dato'Azizan bin Abdul Rahman & Ors v Pinerains Sdn Bhd [2021] MLJU 1414; [2021] 8 CLJ 839 that emphasizes for a party to seek a solicitor's disqualification based on confidentiality, there must first be an established solicitor-client or fiduciary relationship between that counsel and the moving party. In this case, there is an absence of that. [10] Furthermore, the Petitioner has failed to identify or particularize any specific confidential information belonging to him that KDI or even IK allegedly possess. This Court finds that the Petitioner's application rests on vague assertions of conflict rather than clear evidence, failing to meet the high evidentiary threshold required by law. [11] Under Rule 5(b)(ii) of the Practice & Etiquette Rules, a lawyer can act for an opposing party if the first party (the former client) provides written consent. The $ 1^{\mathrm{st}} $ Respondent, who is the only party entitled to claim protection from a conflict involving KDI, has expressly consented in writing to KDI's continued representation of the $ 2^{\mathrm{nd}} $ Respondent. The Petitioner has no standing to invoke the $ 1^{\mathrm{st}} $ Respondent's protection against her own wishes. [12] The Petitioner's contention that IK is a witness to a material disputed fact (specifically the marital rape allegation) cannot be sustained. The Federal Court has held that Rule 28 Practice & Etiquette Rules does not apply to formal and non-contentious roles. Facts show that IK's only role was drafting and sending settlement letters on instructions, which is a formal act that does not make him a witness to the underlying events of the marriage. IK has averred that he has no knowledge as he is not a witness to any such event and he has no personal knowledge of it. His only personal knowledge concerns the formal facts of the drafting and transmission of the three letters which fall within the formal and non-contentious matters described by the Federal Court in Wong Sin Cheong & Anor v Bhagwan Singh & Anor [1993] 3 MLJ 679; [1993] 4 CLJ 345. It thus falls outside the scope of Rule 28 Practice & Etiquette Rules. [13] If this Court needs to explore instructions or alleged contained in solicitors' correspondence, the proper witnesses are the spouses (the Petitioner and the 1 $ ^{st} $ Respondent themselves), not the solicitor who acted merely as a messenger. See Beh Pau Chiang v Lim Sheau Huey [2022] MLJU 1058; [2022] 1 LNS 1104, The solicitor is merely the messenger of the client's instructions and should not be turned into a witness to resolve factual disputes between the spouses. [14] The Petitioner's subpoena against IK relies on the three letters issued by IDK are protected by without prejudice privilege section 23 of the Evidence Act 1950. These letters were settlement communications aimed at inviting the Petitioner to enter a joint divorce petition. Because the contents of these letters are inadmissible at trial, they cannot give rise to any material disputed fact on which IK could testify. The law establishes several barriers to calling a solicitor as a witness to testify about client communications:
