The domain of international investment law is evolving. Today, an increasing number of treaty claims filed against states are based on allegations of a breach of contract. Investment treaty tribunals also tend to affirm jurisdiction over such claims, routinely ignoring that the underlying contract may contain an arbitration agreement in favour of commercial arbitration. This tendency creates a potential jurisdictional conflict between a commercial and investment treaty arbitration proceeding; ripe for investors to exploit. In this context, this article explores the different ways in which investment treaty tribunals have created this jurisdictional conflict. On such basis, it assesses the ameliorative potential of the principle of lis pendens in international arbitration, and whether this potential can be realized in a timely manner.

投资条约与商事仲裁的管辖冲突——待审案件的作用

国际投资法的领域正在演变。今天，越来越多的针对国家的条约索赔是基于违反合同的指控。投资条约法庭也倾向于确认对此类索赔的管辖权，通常忽略基础合同可能包含有利于商业仲裁的仲裁协议。这种趋势在商业和投资条约仲裁程序之间造成了潜在的管辖冲突；投资者可以利用的时机已经成熟。在此背景下，本文探讨了投资条约法庭造成这种管辖权冲突的不同方式。在此基础上，评估未决案件原则在国际仲裁中的改进潜力，以及这种潜力能否及时实现。
