This article discusses the insufficient consideration of the role of state practice in the interpretation and implementation of Article 121(3) of the UNCLOS by the Arbitral Tribunal in the South China Sea Arbitration Case. The article argues that the Tribunal's view on the “threshold” established and its conclusion that there was no evidence that an agreement existed based upon state practice on the interpretation of Article 121(3) are open to question.
