I. SETTING THE STAGE
In recent years ISDS has been on the lips of many politicians, academics, NGOs and even laymen, some of whom have recently ‘discovered’ that there is a mechanism through which foreign investors (often large multinationals, but not always) can bring claims against host-states before an international arbitral tribunal. The arguments in favour and against ISDS are plentiful, but one always catches my eyes. According to this argument (page 3), the EU does not need ISDS in its new free trade and investment agreements (FTIAs) with developed states, because the original rationale of this mechanism was to protect foreign investors from host‑state jurisdictions where basic tenets of the rule of law were not observed. However, trading partners such as the US or Canada have well‑functioning judicial systems that protect foreign investors; therefore, ISDS is not needed.
As a novice to the field of EU investment law, I must confess I am not yet fully convinced by the benefits of ISDS. Nevertheless, the afore-mentioned argument resonates with my previous field of research, concerned with the domestic enforcement of EU and US international agreements, and once again illustrates that there is often a disconnect between the international and the domestic enforcement of treaties.
I will not advocate for the ‘greater’ protection of foreign investors. Instead, I want to shed some critical light on the argument according to which foreign investors already enjoy high levels of protection in advanced domestic judicial systems. I will argue that the domestic protection of foreign investors is more complex. On the one hand, foreign investors can bring a claim before a domestic court against the host-state, invoking domestic standards of protection. On the other hand, they could also potentially bring a claim before the same domestic courts, relying on international standards of investment protection. As I will illustrate, the international and domestic levels of enforcement should not be treated as worlds apart and the interplay between the two can shape the strategies of the treaty negotiators and of the investors.
