If your business has received a Final Decision from the Malaysia Competition Commission (MyCC) imposing a financial penalty or requiring you to cease specific conduct, you have the right to appeal that decision to the Competition Appeal Tribunal (CAT) within 30 days of the decision date. The CAT is the statutory appellate body established under the Competition Commission Act 2010 to hear appeals from MyCC decisions — and it is your primary avenue for challenging findings of infringement, the quantum of penalties, or the remedies imposed.
At NZSK, our competition lawyers in Kuala Lumpur and Selangor advise on the grounds for appeal, the prospects of success, the procedural requirements, and the preparation and conduct of CAT proceedings. We also advise parties — including complainants and third parties — who wish to participate in CAT proceedings or to challenge CAT decisions on further appeal to the Court of Appeal.

The Competition Appeal Tribunal — Jurisdiction and Composition
The Competition Appeal Tribunal (CAT) is established under the Competition Commission Act 2010 as the specialist appellate body for competition law decisions in Malaysia. The CAT consists of a chairman (who must be a person qualified to be appointed as a High Court judge) and two other members — ensuring that the appeal is heard by a body combining legal expertise with competition economics knowledge.
The CAT has jurisdiction to hear appeals from any Final Decision of MyCC, including decisions finding an infringement of the Competition Act, decisions imposing financial penalties, decisions issuing directions to cease conduct or take remedial steps, and decisions refusing to accept a voluntary undertaking or closing an investigation without finding an infringement. Third parties — including complainants whose complaints were rejected by MyCC — also have standing to bring certain appeals.
Grounds for Appeal to the CAT
An appeal to the CAT may challenge a MyCC Final Decision on any ground — including:
- Errors of law — where MyCC has misapplied the provisions of the Competition Act, applied the wrong legal test, or reached a decision that is inconsistent with established legal principles
- Errors of fact — where MyCC’s factual findings are not supported by the evidence, or where MyCC failed to take into account relevant evidence or gave disproportionate weight to irrelevant matters
- Procedural irregularities — where the investigation process was conducted in a manner that prejudiced the enterprise — for example, by failing to provide adequate opportunity to respond to the case against it
- Disproportionate penalty — where the financial penalty imposed is disproportionate to the infringement in the context of the enterprise’s conduct, cooperation, and financial capacity — even where the underlying finding of infringement is accepted
- Incorrect market definition or dominance assessment — particularly in Chapter 2 cases where the finding of dominance or the definition of the relevant market is challenged
The CAT Appeal Process
An appeal is commenced by filing a Notice of Appeal with the CAT within 30 days of the date of MyCC’s Final Decision. The Notice of Appeal must set out the grounds of appeal in sufficient detail. Failure to file within the 30-day deadline will generally bar the appeal entirely — reinforcing the importance of seeking legal advice immediately upon receipt of a Final Decision.
Following the filing of the Notice of Appeal, MyCC will file its response (the Respondent’s Answer) setting out its position on each ground of appeal. The CAT may then permit the filing of further written submissions and will in most cases hold an oral hearing at which both parties present their arguments and answer questions from the Tribunal.
The CAT has wide powers on appeal — it may confirm, vary, or set aside the decision of MyCC, and may remit the matter back to MyCC for reconsideration. In relation to financial penalties, the CAT may increase, reduce, or cancel the penalty. Decisions of the CAT are subject to further appeal to the Court of Appeal and, by leave, to the Federal Court.
Recent CAT Decisions — The Enforcement Landscape
Recent CAT decisions in Malaysia demonstrate that the appellate process is both available and effective. In February 2026, the CAT dismissed appeals brought by several poultry feed companies against MyCC’s 2023 infringement decision, unanimously agreeing with MyCC’s findings regarding coordination in the poultry feed sector. This decision confirms that the CAT conducts a thorough and independent review — and that well-founded appeals can succeed, while poorly founded ones will be dismissed.
The CAT’s role in the Malaysian competition law landscape is growing in importance as MyCC enforcement becomes more active. Understanding the grounds on which CAT appeals are most likely to succeed — and the investment required to mount an effective appeal — is essential in advising on whether to appeal a MyCC decision.
Appealing a Penalty — Even If the Infringement Is Accepted
It is possible to appeal to the CAT in relation to the quantum of a financial penalty even where the underlying finding of infringement is accepted. A penalty that is disproportionate to the nature and duration of the infringement, that fails to take proper account of mitigating factors, or that was calculated on incorrect turnover figures, may be reduced on appeal. We advise on the realistic prospects of a penalty reduction appeal separately from an appeal against the infringement finding.
