5.6 In Chong Fook Sin v. Amanah Raya Bhd & Ors [2010] 7 CLJ 170 917, the Federal Court ruled: '[31] On that footing, it is our judgment that the test of 'legal interest' would still be applicable. However, the legal interest in the issue must be an interest in the subject matter of the appeal before the COA. [32] It would be observed that in some cases, the subject matter of the appeal 175 is the same as the subject matter in the High Court. In such cases, the legal interest would be identical for both. [33] However, there could arise situations where the subject matter of the appeal of the COA is separate and distinct from, although connected to, the subject matter of the proceedings at the High Court. The present 180 appeal presents one such situation. The interveners assert an interest by reason of being beneficiaries in the Estate of the deceased. This is more relevant to the proceedings in the High Court as they stood prior to being struck off. The appeal only concerns ARB's non-compliance with the unless order made against it. This did not and could not involve the 185 interveners qua beneficiaries. [34] In such situations, it is incumbent upon the proposed intervener to establish a legal interest in the subject matter of the appeal before the COA by reference to the matter under consideration in that court. An indirect interest cannot amount to a 'legal interest'. 190 [35] In addition, the intervener application must be made at first instance where the proposed interveners had knowledge of the proceedings in the High Court and the opportunity to take the necessary steps. (See Tradium Sdn Bhd v. Zain Azahari Zainal Abidin & Anor [1996] 2 CLJ 270 and Fairview Schools Bhd v. lndrani Rajaratnam & Ors [1998] 1 CLJ 195 285.) [36] In this regard, 'opportunity' must be understood as meaning legal avenue and entitlement to make such an application. Quite apart from the requisite 'legal interest', an applicant must establish that he is not precluded by any other circumstances from making such an application. 200 [37] Such precluding circumstances would include a prior determination of the courts that gave rise to an issue estoppel, such as to attract the doctrine of res judicata. A party so impeded would not be in a position to seek leave to intervene.” 205 5.7 The appellant further submitted that the proposed intervener has not demonstrated any legal interest in the affidavit filed other than merely stating it has a duty to look into the conduct of an advocate and solicitor, which befittingly has been thoroughly looked into by the ASDB. The proposed intervener was represented at all stages, 210 right from the point the complaint was lodged to the handing down of the punishment to the appellant. The appellant prays that the present application be dismissed without an order for costs. THE LAW 215 [6] The Bar Council has the right to intervene at any stage of an appeal against a decision of the DB pursuant to section 103E (6) of the LPA read together with O.15 r.6(2)(b) RC 2012 because it is the duty of the Bar Council to maintain the standard and conduct of advocates and solicitors pursuant to section 42 of the LPA and the 220 Bar Council’s role is to assist the Court in determining whether the finding of misconduct by the DB can be sustained Section 103E (6) LPA provides: “103E Appeal from the decision of the Disciplinary Board 225 …
