REPUBLIC OF KOREA v MASON CAPITAL L.P. & Anor [2025] SGHC(I) 9 (20 March 2025)

REPUBLIC OF KOREA v MASON CAPITAL L.P. & Anor [2025] SGHC(I) 9 (20 March 2025)

The court held that the requirements of 'measures adopted or maintained' and 'relating to' in the FTA are not jurisdictional limitations on the tribunal's authority but go to the merits of the claim. The acts of ROK officials, though illegal, constituted measures under the FTA, and had a legally significant connection to Mason and their investment. Mason Management LLC qualified as an investor under the FTA. The tribunal's refusal to admit further evidence did not breach natural justice. Accordingly, there were no grounds to set aside the award.

Procedural Posture

Originating Application and Summons to Set Aside Arbitral Award / Final Judgment on Application to Set Aside Arbitral Award

Legal Issues

  1. 1 Whether the acts impugned by Mason constituted 'measures adopted or maintained' by ROK under the FTA
  2. 2 Whether the acts were 'relating to' Mason or their investment under the FTA

Ratio Decidendi

The court held that the requirements of 'measures adopted or maintained' and 'relating to' in the FTA are not jurisdictional limitations on the tribunal's authority but go to the merits of the claim. The acts of ROK officials, though illegal, constituted measures under the FTA, and had a legally significant connection to Mason and their investment. Mason Management LLC qualified as an investor under the FTA. The tribunal's refusal to admit further evidence did not breach natural justice. Accordingly, there were no grounds to set aside the award.

Court Disposition
