Paris Court Sets December Date for Ruling on Sulu Funded Award Annulment
A critical procedural milestone has been set in the high-profile dispute over the $15 billion arbitral award claimed by the heirs of the defunct Sulu sultanate against Malaysia. A Paris court has scheduled a hearing for December 9, where it will decide whether to annul the partial award issued by a Spanish arbitrator—a decision with potentially far-reaching implications for the legitimacy of third-party funded arbitration in sovereign disputes.
As reported by The Malaysian Reserve, the case stems from a 2022 ruling which found Malaysia liable for ceasing annual payments related to a 19th-century lease of territory now part of Sabah. The award has been described as one of the largest in arbitration history and is backed by Therium, a UK-based litigation funder. Malaysia has consistently challenged the legitimacy of the proceedings, resulting in conflicting decisions in courts across Spain, France, and Luxembourg.
The upcoming Paris ruling will not address the full $15 billion award but rather the validity of the partial award that formed the foundation for the final judgment. Malaysia’s legal representatives argue that the arbitration itself is void, citing breaches in due process and the arbitrator's alleged overreach.
The Sulu case has become a lightning rod in debates over state immunity, the enforceability of investor-state arbitration, and the role of third-party funders in politically sensitive disputes. As funders continue to back complex claims against sovereign states, the Paris court’s decision may set a significant precedent for the enforceability—and reversibility—of arbitral awards financed by external capital.
