Alta‘s impressive dispute resolution practice covers the full scope of high-stakes commercial, criminal, administrative and constitutional litigation, as well as national and international arbitration. While it is well equipped to handle disputes across the retail, automotive, dairy and finance sectors, the team is particularly recognised for its skill in energy and mining-related cases, with a stellar recent record in complex constitutional litigation and high-profile international arbitration in this sphere. Practice head Alejandro Solares Morales, who draws significant praise for his ’strategic vision, analytical skills and leadership in complex cases‘, covers the full spectrum of domestic and cross-border litigation and arbitration, while senior partners Marcos Ibargüen, ’excellent strategist‘ José Quiñones and energy specialist Alejandro Cofiño are also key contacts. The strong cohort of junior lawyers includes senior associates Luis Pedro Martínez, described as an ’emerging star‘, and the arbitration-focused Ignacio Grazioso, and associate Estuardo Marchena, who is particularly active in energy disputes.
