Pedro Metello de Nápoles and Ana Trigo Coimbra helped prepare the study "Las Interferencias de las Constituciones Políticas de los Países de Iberoamérica en el Desarrollo del Arbitraje Internacional" ("The Interferences of the Political Constitutions of the Countries of Ibero-America in the Development of International Arbitration"). This study was organised and published by the ICC World Business Institute. The contributions from PLMJ's lawyers focused on research into arbitration and constitutional law.
