摘要 英國脫歐乃當今備受全球關注的重大經貿事件,而英國脫歐將引發英國與歐盟彼此間,及英國與歐盟以外的第三國間在經貿關係上的調整問題。其中,英國之雙邊投資保障政策勢必因脫歐而有所調整,即屬適例。例如:英國與歐盟成員國間或歐盟與第三國所簽署的雙邊投資保障協定,於脫歐後之效力為何?此問題固需視脫歐協議的內容有無具體安排而定;然在脫歐協議前景不明之情形下,英國之海外投資人業已關切脫歐所可能造成的投資損害。對此,關於脫歐所導致的法規與制度改變是否損及海外投資人之合理期待,進而違反雙邊投資保障協定下之公平公正待遇義務,儼然成為國際投資法下一項潛在問題。尤其在既有雙邊投資保障協定仍訂有投資人與地主國爭端解決機制的情況下,是否可能因此引發投資人提出國際投資仲裁爭端之控訴,亦為英國政府於制訂脫歐後的投資保障政策時所需考量的問題。因此,本文著重於英國脫歐後對投資保障規範與政其策的影響,探討英國脫歐所致法令與制度的改變是否違反英國於雙邊投資協定下有關公平與公正待遇義務?檢視既有國際投資仲裁案例,例如西班牙、阿根廷之案例,藉以探討英國脫歐是否及在何等情況下將損及該等義務所保障英國海外投資人在英國投資之合理期待。
As a major economic and trade event attracted worldwide attention, Brexit will trigger adjustments in bilateral economic and trade relations between Britain and the European Union (EU) and between Britain and non-EU third countries. Among them, Britain's bilateral investment protection policy is bound to be adjusted due to Brexit. For example: What is the effect of the bilateral investment treaty (BIT) signed between the United Kingdom (UK) and EU member states or the EU and a third country after Brexit? This issue largely depends on what specific arrangements will be made under the Withdrawal Agreement, if any. However, since the destiny of the Withdrawal Agreement is uncertain so far, foreign investors in the UK have been concerned about the possible investment loss caused by Brexit. In this regard, whether the regulatory or regime changes due to Brexit have infringed the legitimate expectations of foreign investors and further violated the fair and equitable treatment obligation under BITs has been identified as a potential issue for the UK. Especially when the investor-state dispute settlement (ISDS) mechanism is still available under UK BITs, it has been fiercely debated over the possibility for triggering ISDS complaints against UK’ policy change due to Brexit. This issue could also be one of the policy considerations for the British government to formulate investment protection policies after Brexit. Therefore, this research project focuses on the impact of Brexit on UK’s investment protection policies, and explores whether the changes in the laws and regulations caused by Brexit will violate the UK's obligations regarding fair and just treatment under BITs? Specifically, by referring to previous investment cases, such as those involved with Spain and Argentina, to explore whether and under what circumstances the realization of Brexit will undermine the legitimate expectations of foreign investors in the UK.
