Misuse of Mutual Legal Assistance and Cross-Border Notices: A Structural Risk Assessment for Procedural Safeguards and Trust in International Cooperation in Latin America

This independent analytical report examines structural risks associated with the misuse or perceived misuse of mutual legal assistance (MLA) mechanisms, extradition requests, and cross-border notices within Latin America’s international legal cooperation framework. While MLA remains an essential instrument for combating transnational crime, its effectiveness depends on mutual trust between jurisdictions and adherence to fundamental procedural safeguards. The report analyzes vulnerabilities arising from asymmetries in evidentiary standards, judicial oversight, and procedural protections across jurisdictions. Particular attention is given to scenarios in which international legal cooperation mechanisms may be used in the context of corporate conflicts, politically sensitive proceedings, or weakly substantiated cases. In such situations, requested states may unintentionally legitimize disproportionate measures, including arrests, asset freezes, mobility restrictions, and reputational harm. The study identifies recurring patterns of misuse, evaluates the risk of “exporting weak procedural standards” through cross-border cooperation channels, and examines secondary effects on banking relationships, investment climate stability, and financial de-risking. A structured “Procedural Safeguard Checklist” is introduced as a practical tool for assessing incoming requests and strengthening proportionality and evidentiary scrutiny. Policy-oriented recommendations are provided for the Organization of American States (OAS), national central authorities for MLA, ministries of justice, judicial institutions, and development partners. These recommendations focus on enhancing quality-control mechanisms, transparency standards, and proportionality frameworks to preserve both effectiveness and legitimacy of international legal cooperation. Prepared by ARGA Observatory, this report is intended for policymakers, judicial and regulatory authorities, development institutions, financial sector stakeholders, legal practitioners, and academic researchers engaged in international legal cooperation, rule-of-law governance, and institutional resilience in Latin America.
