Amicus Curiae Intervention in China-ASEAN Investment Disputes: Rationale, Dilemmas and Reform Path

Abstract

One main criticism levelled against the investor-state dispute settlement system (ISDS) is the existence of limited opportunities for amicus intervention. Against this backdrop, this article firstly studies what reforms regarding amicus intervention in ISDS proceedings have been put forward by China and ASEAN countries and the relevant dilemmas. Subsequently, to ensure that maximum benefits can be realised from amicus participation in ISDS proceedings in China-ASEAN Free Trade Area (CAFTA), this article proposes procedures for when and how an amicus may participate in arbitral proceedings under the upcoming investment agreements, particularly the Regional Comprehensive Economic Partnership (RCEP). Additionally, given the fact that the level of amicus participation in ISDS proceedings is still limited, the article suggests that China and ASEAN need to establish safeguards to provide amici with access to key arbitral documents and oral hearings. However, achieving the above objectives should not come at the expense of undermining the confidential and protected information of both disputing parties.
