Analyser les lois nationales sur l’investissement : fonction de règlement des litiges

This report by the International Institute for Sustainable Development (IISD) analyzes the dispute settlement functions within 167 national investment laws. It examines the prevalence of various mechanisms—including national courts, arbitration, administrative review, and amicable settlements—and provides a framework for policymakers to design or reform these laws to minimize legal and financial risks, specifically warning against the inclusion of prior consent to international arbitration.

• An analysis of 167 national investment laws shows that nearly 79% contain provisions related to the prevention, management, and settlement of disputes (PGRD). This function is most prevalent in Africa (91%) and Asia (84%).
• National courts are a common option for dispute resolution, mentioned in approximately 57% of laws with a PGRD function. Approaches vary from requiring exclusive use of national courts (e.g., Armenia, El Salvador, and Kenya) to requiring the exhaustion of local remedies before seeking alternatives (e.g., Sierra Leone and Equatorial Guinea).
• Arbitration is referenced in 69% of laws with a PGRD function, though it is never designated as the primary method. Distribution varies by region: 46.51% of African laws mention only international arbitration, while 51.72% of Asian laws allow both national and international arbitration.
• Among laws referencing arbitration, 44% include 'prior consent,' and another 14 laws contain provisions that could be interpreted as such. This practice exposes states to significant financial and regulatory risks, including high legal costs (averaging 5 million USD) and high average awards (256 million USD between 2014 and 2023).
• Non-jurisdictional mechanisms are appearing but remain less common: 42% of laws allow methods agreed upon by the parties, 39% provide for administrative review, and 32% mention amicable settlements (negotiation or mediation).
• The use of amicable settlement mechanisms (MRA) is more frequent in emerging and developing economies (31%) than in advanced economies (10%), often serving as a prerequisite before proceeding to arbitration.
• Only 13.64% of the analyzed investment laws establish national institutions specifically for the prevention and management of disputes. Africa has the highest number of such institutions (10), followed by Asia (6).
• The report strongly recommends that states avoid including prior consent to international arbitration in their investment laws. Instead, laws should recognize arbitration as a valid option to be agreed upon on a case-by-case basis or through specific contracts.
