Arrieta Mantilla & Asociados

Finding favour for its ‘ability to integrate and anticipate risks’, Arrieta Mantilla & Asociados’ practice is weighted towards representing energy and natural resources clients — primarily mining companies — in regulatory and administrative law matters, including judicial litigation. High-profile public law expert Carlos Gustavo Arrieta impresses with his ’experience and good judgment’; he is currently representing AES Colombia in two judicial proceedings challenging the divestiture of the Chivor hydroelectric plant. Yady Villaquirán co-heads the department together with Arrieta and is noted for her representation of mining companies in administrative and judicial procedures, including recent engagements for Zijin-Continental Gold and Cerrejón Zona Norte, among others. The group also includes infrastructure and energy-focused associate Rodrigo Sánchez Pineda, who is ‘very committed, resourceful, and innovative’.
