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

The report examines how national investment laws handle the prevention, management, and settlement of disputes between investors and states. Based on an analysis of 167 laws, it finds that while dispute resolution is a common feature—particularly in Africa and Asia—the use of international arbitration and 'prior consent' clauses exposes states to significant financial and regulatory risks. The authors argue that states should prioritize national courts and administrative reviews over parallel arbitration systems and strongly recommend against including unilateral prior consent to international arbitration in national legislation.

• Dispute resolution provisions are common in national investment laws, appearing in nearly 79% of the 167 laws analyzed, with the highest prevalence found in Africa (91%) and Asia (84%).
• National courts are explicitly mentioned in approximately 57% of investment laws that include dispute resolution functions. Approaches vary from requiring exclusive use of national courts (e.g., Armenia, El Salvador, Kenya) to requiring the exhaustion of local remedies before seeking alternatives (e.g., Sierra Leone, Equatorial Guinea).
• Arbitration is referenced in 69% of laws with dispute resolution functions, but it is never the primary method. Distribution varies by region: 46.51% of African laws mention only international arbitration, while Asia and Europe frequently use a mix of national and international arbitration.
• Approximately 44% of laws referencing arbitration contain 'prior consent' clauses. This practice is linked to high financial and regulatory risks, including an average legal cost of 5 million USD for states and an average award of 256 million USD between 2014 and 2023.
• Non-jurisdictional mechanisms are less common: 42% of laws allow methods agreed upon by parties, 39% provide for administrative review, and 32% mention amicable settlement (negotiation or mediation).
• Only 13.64% of the analyzed investment laws establish national institutions specifically for the prevention and management of disputes, with Africa having the highest number of such institutions (10).
• The report strongly advises states to avoid including unilateral prior consent to international arbitration in national laws, suggesting instead that arbitration be recognized as an option requiring case-by-case or contractual agreements.
