Foreign investment in the privatization of water services can help to promote the realization of the human right to water. However, there are instances where this has not been the case, resulting in disputes between host States and foreign investors that are brought to international arbitration. Given that these cases are at the intersection of investment and human rights, amici curiae have applied for standing and made submissions. This article explores the procedural and substantive roles of amicus curiae in implementing the right to water in the context of international investment law. The procedural role includes their contribution to the establishment of amicus curiae mechanisms which, in turn, becomes a vehicle for further amicus curiae participation. Substantively, amicus curiae could further develop the argument of the right to water through their submissions, which could influence arbitral proceedings. Ultimately, both roles assist in the implementation of the human right to water.

法庭之友在国际投资法范围内在执行水权方面的作用

外国对水服务私有化的投资可以帮助促进实现水的人权。但是，在某些情况下并非如此，导致东道国与外国投资者之间的争端被带到国际仲裁中。鉴于这些案件处于投资与人权的交汇处，因此法庭律师已提出诉讼并提出申诉。本文探讨了法庭之友在国际投资法范围内在行使水权方面的程序性和实质性作用。程序性角色包括它们对建立法庭之友机制的贡献，而这些机制反过来又成为进一步法庭之友的工具参与。实质上，法庭之友可以通过其来文进一步发展关于水权的论点，这可能会影响仲裁程序。最终，这两个角色都有助于实现水的人权。
