Análisis de las leyes nacionales de inversión: la función de solución de controversias

This executive summary, published by the International Institute for Sustainable Development (IISD) in April 2026, analyzes the dispute settlement functions within national investment laws. Based on a study of 167 laws, it examines the prevalence of dispute prevention, management, and settlement (DPMS) provisions, the role of national courts versus arbitration, and the risks associated with providing prior consent to arbitration. The document provides a framework for policymakers to reform investment legislation to minimize financial and regulatory risks.

• An analysis of 167 national investment laws shows that dispute prevention, management, and settlement (DPMS) provisions are common, appearing in nearly 79% of the laws studied. The highest rates of inclusion are found in Africa (91%) and Asia (84%).
• National courts and arbitration are key mechanisms in these laws. Approximately 57% of laws with DPMS functions explicitly mention national courts, with some requiring their exclusive use or the exhaustion of local remedies. Arbitration is referenced in 69% of laws with DPMS functions, though it is rarely the primary mechanism.
• Prior consent to arbitration is present in 44% of the laws that reference arbitration. The report warns that this practice replicates the significant financial and regulatory risks associated with investor-State dispute settlement under international treaties.
• Non-judicial alternative mechanisms are emerging but remain less common than courts or arbitration. These include methods agreed upon by parties (42%), administrative review (39%), and amicable settlement through negotiation or mediation (32%).
• The report recommends that States avoid including prior consent to international arbitration in investment laws. It suggests that if arbitration is necessary, it should be based on case-by-case agreements or specific contracts rather than unilateral, indefinite consent to an undetermined group of investors.
