論投資條約仲裁視域下國內法的法律地位

Research on the Legal Status of the Domestic Law from the Perspective of the Investment Treaty Arbitration

東道國國內法的法律地位與功能，在投資條約仲裁實踐中並沒有得到較好的明確，仲裁庭在適用國內法的認識上仍然存在分歧。並且，東道國國內法也時常被仲裁庭忽視或誤用。根據《華盛頓公約》第42條第1款的規定，東道國國內法和可能適用的國際法都可作為仲裁庭的法律依據。這表明，東道國國內法在投資仲裁中具有重要的法律地位，仲裁庭應給予足夠的重視。在某些情形下，東道國國內法對仲裁庭判斷東道國行為在國際法上的正當性具有重要影響。為明確東道國國內法的地位與功能，需要以修正的一元論作為理論基礎，即國內法的法律地位需要以國際法優先於國內法的一元論為基本立場，同時結合內在聯繫論進行科學認識。

The legal status and function of the domestic law of the host state have not been well defined in the practice of investment treaty arbitration, and the arbitral tribunal still has different understandings when it is necessary to apply the domestic law. Moreover, the domestic law of the host state is often ignored or misapplied by the tribunal. In accordance with article 42. 1 of the Convention on the Settlement of Investment Disputes Between States and Nationals of Other States, both the domestic law of the host state and the applicable international law may be the legal basis for the arbitral tribunal. This shows that the domestic law of the host state is the law that should be paid attention to and considered in the application of investment treaty arbitration. In some cases, the domestic law of the host state has a significant impact on the arbitral tribunal's determination of the legitimacy of the host state's conduct under international law. In order to clarify the status and function of the domestic law of the host state, it is necessary to take the revised monism as the theoretical basis, that is, the legal status of domestic law should be based on the monism that international law takes precedence over domestic law, and at the same time, it should be scientifically understood in combination with the theory of internal connection.
