Les tiers dans le contentieux arbitral des investissements internationaux : de l'intervention au recours direct
International arbitration has remained an exclusive domain sovereign states until, in the late 50s, came the first bilateral investment treaties (BITs). The main feature of these BITs is undoubtedly the right, granted to investors, to direct international arbitration against recalcitrant States, an alternative to often ineffective local justice. More recently, in 1998, the appellate body of the WTO went to accept the opinion of an independent amicus curiae in a dispute between State members. Today, the admission of such opinions is clearly provided for in several recent BITs. But if investors benefit from a right of action before a neutral international arbitration body, the situation is quite different for the local population, who is often affected by the presence of foreign investors on its territory. The right to submit an opinion cannot replace the right to legal action. This therefore raises one question: in the current context of international investment law, is it possible for third parties (non signatories of BITs and not parties to the dispute) are entitled to a remedy direct international arbitration? We are of the opinion that the answer to this question is: yes. And the context of investment arbitration, because of the right to direct arbitration against States already granted to investors, constitutes a fertile ground for the implementation of this right of action in favour of third parties. The objection based on the absence of the parties’ consent to such right of action has been set aside in many international arbitration cases where the scope of consent has been extended to include non-parties or to submit to arbitration matters not contemplated at first. Also, the objection based on the absence of legal standing of third parties in International Law proves to be theoretical as foreign investors already have access to international justice despite the lack of this quality. There remains to determine what substantial International Law will constitute a valid legal basis for a third party claim. We will see that there exists legal instruments and international principles and that their violation by States or investors may result in the obligation to compensate the prejudice suffered, as well as it is possible to clearly define and indentify who the third parties could be.
