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

This executive summary, published by the International Institute for Sustainable Development (IISD) in April 2026, analyzes the dispute settlement functions within 167 national investment laws. It examines the prevalence of dispute prevention, management, and settlement (PGRD) provisions, highlighting the risks associated with 'prior consent' to arbitration and providing a framework for policymakers to reform national investment laws to minimize legal and financial risks.

• An analysis of 167 national investment laws shows that dispute prevention, management, and settlement (PGRD) functions are common, appearing in nearly 79% of the laws studied. This prevalence is highest in Africa at 91% and Asia at 84%.
• National courts and arbitration are frequently cited in laws with PGRD functions. Approximately 57% of these laws explicitly mention national courts, while 69% refer to arbitration, although arbitration is never the primary method designated.
• Among laws that refer to arbitration, 44% include 'prior consent,' a practice that the report warns reproduces the significant financial and regulatory risks associated with investor-State dispute settlement via treaties.
• Non-jurisdictional alternative mechanisms are less common: 42% of laws allow methods agreed upon by parties (more frequent in Asia and Africa), 39% provide for administrative review, and 32% mention amicable settlement through negotiation or mediation.
• The report strongly advises states against including prior consent to international arbitration in investment laws. It suggests that if arbitration is necessary, it should be handled via case-by-case agreements or specific contracts rather than unilateral consent to an undefined category of investors, which creates uncontrollable legal and financial risks.
