A joint statement by five civil society organizations requesting transparency and the ability to participate as amicus curiae in ICSID Case No. ARB/03/19. The case involves a dispute between the Republic of Argentina and several companies, including Aguas Argentinas S.A., regarding economic measures adopted during the 2002 crisis that affected water and sanitation services.

• The dispute centers on whether the Argentine government's 2002 economic crisis measures—specifically currency devaluation, tariff freezing, and the prohibition of indexing tariffs to US price indices—violated the 1991 Bilateral Investment Treaty (BIT) between Argentina and France.
• The petitioners argue that the case has immense public significance because it concerns the state's regulatory capacity over essential public services, directly affecting millions of residents in Greater Buenos Aires who rely on water and sanitation services.
• The organizations claim that the lack of transparency in the proceedings allows foreign investors to use ICSID arbitration as a pressure tactic to obtain favorable contractual renegotiations from the state.
• The petitioners assert that the tribunal has the 'inherent powers' to order transparency and allow public participation, citing precedents from the International Court of Justice, the ICTY, and the Enron v. Argentina case.
• The document cites a global trend toward transparency in international investment law, noting that NAFTA tribunals (e.g., Methanex and UPS), the WTO, and new-generation BITs (such as those between Chile-USA and Singapore-USA) have increasingly allowed amicus curiae submissions and open hearings.
