Supreme Court’s Decision The Supreme Court affirmed the Seoul High Court’s decision and dismissed the appeal, providing detailed guidance on the proper scope of judicial review in enforcement proceedings. The Supreme Court reit - erated that arbitration is a private dispute resolution mechanism, and awards rendered through such pro - ceedings are granted the same legal effect as final court judgments – unless recognition or enforcement is refused on limited grounds set out in the KAA or the Convention on the Recognition and Enforcement of Foreign Arbitral Awards (the “New York Convention”) To reconcile party autonomy with the state’s exclu - sive authority over enforcement, Korean law requires a judicial grant of enforceability (exequatur). In par - ticular, Article 37 (2) of the Korean Arbitration Act pro - vides that “an arbitral award may be enforced only by a court’s decision to enforce it upon the request of the parties.” For foreign arbitral awards governed by the New York Convention, courts may refuse enforcement only on the narrow grounds specified in the Conven - tion, as incorporated in Article 39 (1) of the KAA. Given the foundational principle that arbitration is a party-driven, private mechanism of adjudication, and in light of the KAA’s and the New York Convention’s shared approach of conferring arbitral awards with the same force as court judgments while strictly limiting grounds for refusal, it follows that Korean enforce - ment courts should, in principle, afford arbitral awards a level of legal effect equivalent to that of domestic judgments. This principle holds even where the form, structure, or language of the arbitral award – particu - larly in the case of foreign-seated arbitrations – may not conform precisely to the drafting conventions or specificity requirements typically expected under the Korean Civil Execution Act. Accordingly, even where certain aspects of the dis - positive section of an arbitral award appear unclear or incomplete, it falls within the proper authority of the enforcement court to grant enforcement – provided that the ambiguities can be resolved by interpreting the dispositive section in conjunction with the reason - ing of the award. In such cases, the court may confirm the substance of the award with sufficient clarity, with -

out exceeding its jurisdiction or impermissibly revisit - ing the merits of the dispute. However, even in such circumstances, the enforce - ment decision must be based exclusively on the contents of the dispositive section and the reason - ing set forth in the arbitral award itself. The court is not permitted to supplement or modify the award by re-examining the tribunal’s substantive findings of fact or legal conclusions. Moreover, where the con - tent of the award is already clear and unambiguous, the court may not expand its scope, apply analogical interpretation, or otherwise alter its meaning by refer - ence to external materials beyond the four corners of the award. Conclusion Overall, arbitration continues to play a vital role in resolving international commercial disputes, providing parties with a neutral and expert forum – particularly where cross-border transactions are involved. How - ever, unlike domestic court judgments, arbitral awards – especially foreign ones – are not bound by uniform formal requirements. Their form and structure often vary depending on the seat of arbitration, the applica - ble procedural rules, and the governing law. Under Korean law, enforcement of such awards requires a separate judicial procedure. Difficulties may arise when the dispositive section does not conform to the Korean Civil Execution Act’s expectations for specificity. Nevertheless, the KAA and the New York Convention both provide that arbitral awards must be treated with the same legal force and effect as court judgments, subject only to narrow exceptions. In light of the private and international nature of arbi - tration, it is both necessary and desirable for Korean courts to adopt a flexible and supportive approach when reviewing foreign arbitral awards. Even where the dispositive section is ambiguous or incomplete, the courts may – and should – interpret it in con - junction with the reasoning of the award to clarify its meaning, provided such interpretation remains within the bounds of the award itself. However, this authority is not unlimited: the enforcement court must not re- evaluate the tribunal’s factual or legal determinations,
