Abstract

Amicus curiae is a developing feature of modern international investment arbitration. This chapter starts by describing how investment arbitration shifted from a confidentiality-based practice to a model that is more open to the participation of civil society. It then proceeds to discuss the potential benefits and drawbacks of allowing the participation of non-disputing parties in investment arbitration. Amicus curiae is a useful tool to increase the transparency of the dispute settlement mechanism and serves as a fundamental gateway for public participation in the arbitration process. However, its benefits need to be weighed against potential disadvantages, such as the risk of politicization of disputes, an increase in the costs and length of the proceedings, and a negative impact on party equality. Arbitral tribunals must ensure that amicus curiae participation creates added value and does not undermine the purposes of the dispute settlement mechanism. In order to strike this balance, tribunals should only accept submissions from individuals or organizations who offer guarantees of independence, autonomy, and credibility.

    A related question regards the existence of possible connections between those preparing or submitting amicus briefs and those connected in some way to the dispute such as lawyers, witnesses, judges, or staff. Since the field of international investment arbitration is very specialized, there are a limited number of professionals working in this area, causing the existence of connections between them to be more common than could be expected.
