Before the Federal Court: Arguing Questions of Res Judicata and Natural Justice
On 18 June 2026, our Managing Partner, Ko Jie Yang with his reliable legal associates, had the privilege of appearing before the Federal Court of Malaysia in a leave to appeal application involving significant questions of law concerning the doctrines of res judicata, privy, and natural justice.
The matter was heard before an esteemed panel comprising:
- The Right Honourable Tun Wan Ahmad Farid bin Wan Salleh, Chief Justice of Malaysia;
- The Right Honourable Datuk Seri Hashim bin Hamzah, Chief Judge of Malaya; and
- The Honourable Dato’ Nordin bin Hassan, Federal Court Judge.
Questions of Law Before the Federal Court
The leave application raised important legal questions relating to the scope and application of the doctrine of res judicata, particularly whether the doctrine may extend to parties who were not formally named in previous proceedings but are considered privies to the original parties.
The application also involved considerations relating to natural justice, including whether a party should be precluded from litigating a matter where they were not directly involved in earlier proceedings.
These issues are significant because they concern the balance between:
- The principle of finality in litigation;
- The prevention of abuse of court process; and
- The fundamental right of a litigant to be heard.
Federal Court’s Decision
Following submissions from counsel, the Federal Court ultimately held that the doctrine of res judicata applies to privies.
The decision reinforces the established principle that parties who are sufficiently connected to or derive their interests through parties in earlier proceedings may be bound by the outcome of those proceedings, notwithstanding that they were not formally named as parties in the earlier action.
The ruling serves as an important reminder that litigants cannot circumvent the doctrine of res judicata merely by bringing proceedings through or on behalf of persons whose interests are substantially identical to those already determined by the courts.
Importance of the Decision
The doctrine of res judicata plays a crucial role in ensuring certainty and finality in legal disputes. Without it, parties could potentially re-litigate the same issues repeatedly, resulting in inconsistent judgments and unnecessary use of judicial resources.
At the same time, courts must carefully consider the requirements of natural justice to ensure that litigants are not unfairly deprived of an opportunity to present their case.
The Federal Court’s decision provides further guidance on how these important principles are to be reconciled where questions of privity arise.
