International arbitration depends on a balance between procedural fairness and efficient case management. Tribunals must give parties a fair opportunity to present their cases while retaining sufficient control to prevent unnecessary delay. The difficulty arises when fear of a potential challenge causes tribunals to become excessively cautious in exercising their procedural powers.
This tension is evident in “due process paranoia”—a tribunal’s excessive concern that a procedural decision may later be characterised as a denial of due process and used to challenge the award. Such apprehension may encourage tribunals to grant repeated or unmeritorious applications. Paradoxically, measures intended to safeguard due process may allow one party to gain procedural advantages, prolong proceedings, and compromise equality and efficiency.
The Singapore Court of Appeal’s decision in China Machine New Energy Corp v Jaguar Energy Guatemala LLC [2020] SGCA 12 (“Jaguar Energy”) illustrates this problem. The court highlighted the danger of “defensive procedural decision making”, where tribunals become excessively cautious because of potential challenges. Fear of being perceived as procedurally unfair may therefore cause tribunals to accommodate requests that could reasonably be rejected.
This is reinforced by Anwar Siraj and Another v Ting Kang Chung, where the Singapore High Court described the tribunal as the “master of his own procedure”, with broad discretion to conduct proceedings provided its approach is not manifestly unfair or contrary to natural justice. Due process does not require tribunals to grant every application; fairness must coexist with effective case management. Tribunals may therefore reject unmeritorious applications, refuse extensions, control evidence, and determine how proceedings should be conducted. A party’s dissatisfaction with such decisions will not, without more, justify setting aside an award. The concern arises when procedural discretion results in genuine unfairness or unequal treatment.
The limits of that discretion are illustrated by Rice Trading (Guyana) Ltd v Nidera (“Nidera”), where the Dutch Court of Appeals upheld the setting aside of an award after the tribunal admitted new evidence without giving the opposing party sufficient opportunity to respond. Similarly, in A v B [2024] HKCFI 75, the Hong Kong Court of First Instance set aside an award after the tribunal permitted time-barred claims without adequately addressing the limitation defence. In both cases, the tribunal’s approach materially affected one party’s ability to present its case.
These cases expose the paradox of due process paranoia. Excessive concern about procedural fairness may lead tribunals to accommodate requests indiscriminately, producing inequality and inefficiency. Conversely, exercising procedural powers too aggressively may deprive a party of its right to be heard and expose the award to challenge.
The case law therefore suggests that due process requires not excessive caution, but proportionate procedural discretion. Tribunals must distinguish legitimate applications from tactical requests designed to delay proceedings or secure an advantage.
