On the court record
Engages the setting aside and enforcement of arbitral awards under section 37 of the Arbitration Act 2005 and the boundary between a natural-justice challenge and an impermissible appeal on the merits.
Tunku Ahmad Munawwir bin Tunku Ahmad Mustaffa's appearances in this corpus, all in the High Court (Mahkamah Tinggi), engage construction arbitration and land development. As counsel for the plaintiff he acted in an application to set aside an arbitral award under section 37 of the Arbitration Act 2005, arising from a construction dispute. The grounds advanced included an alleged breach of natural justice — whether the arbitrator had failed to consider material submissions, and whether expert-witness evidence should be considered where it conflicted with contemporaneous evidence. A central question, recurring in award-challenge cases, was whether the complaints in truth amounted to a challenge to the merits and to the arbitrator's interpretation of the contract, dressed up as a natural-justice or public-policy objection. Section 37 permits a court to set aside an award only on narrow grounds, and the court's task was to distinguish a genuine procedural defect from disagreement with the outcome. In the connected proceeding he appeared as counsel for the respondent, the positions of the parties being reversed as the enforcement and set-aside applications were heard together.
He also acted as counsel for plaintiffs in a matter concerning a development, where the court dealt with a "rayuan" (appeal) against a decision allowing an originating summons with costs. The parties included a statutory development corporation and connected companies, and the dispute arose out of the administration of a hill-development project.
Across these matters, Tunku Ahmad Munawwir bin Tunku Ahmad Mustaffa's practice engages the setting aside and enforcement of arbitral awards under the Arbitration Act 2005 — in particular the boundary between a permissible natural-justice challenge and an impermissible appeal on the merits — and litigation arising from land-development projects. As counsel appearing on both sides of the linked award proceedings, his role was to argue the competing set-aside and enforcement positions before the court.
