(iii) the decision of the Federal Court must have the effect of bringing the determination of the dispute to a speedy and economical end. 11 [16] So, the first issue is whether the constitutional question sought to be referred to the Federal Court have a direct bearing to the matter of dispute in this application. Prayer (ii) of the Originating Summons is on the interpretation of article 5(1), 8 and/or 9 of the Federal Constitution. However, the main constitutional issue raised by learned counsel in this application under s. 84 CJA 1964 is the validity of the case of Loh Wai Kong (supra) in light of article 121 of the Federal Constitution.

[19] I am of the considered opinion that the constitutional issues raised in this case have been decided in many cases, including Loh Wai Kong (supra), Pihak Berkuasa Negeri Sabah v. Sugumar 12 Balakrishnan (supra) and Pua Kiam Wee’s case. Therefore, it cannot be said that there are ambiguities to the interpretation of these provisions that requires a speedy and final determination by the Federal Court.

[21] On the substantive application, parties are on common ground that this court is bound by the decision in several cases, the latest is Pua Kiam Wee’s decision. In Pua Kiam Wee’s case, the Court of Appeal has held, inter alia:
