Roberto Burgos

Commended by clients for an 'exceptional level of knowledge, depth of analysis, availability and involvement', Guerrero Olivos' public law department stands out for its administrative and constitutional law expertise across Chile’s most regulated sectors. The group routinely advises major domestic and international clients in industries such as mining, energy, infrastructure, financial services and telecoms. The team offers end-to-end support, from navigating complex regulatory processes and public procurement to securing permits and handling constitutional litigation. It is frequently sought out to challenge sanctions, support concession holders and engage in high-stakes administrative disputes. Recent high profile matters include advising Nestlé on its challenge of a Chilean ministry of health regulation affecting food advertising; and successfully challenging the classification of three subsidiaries of Antofagasta Minerals as “strategic” entities before the Court of Appeal, avoiding significant security-related costs. The practice is co-led by Eduardo Cordero, an expert in constitutional and administrative law, known for his deep experience representing major regulated entities before the Supreme and Constitutional Courts; he is routinely called on to provide expert legal opinions by peers and top-tier clients such as Codelco, Banco BCI and Mutual de Seguros de Chile. Praised for his ‘availability and ability to propose strategies’, fellow co-head José Gabriel Undurraga is recognised for his litigation and procurement work for companies such as Nestlé and Antofagasta Minerals. Senior associate Roberto Burgos brings specialist expertise across public tenders, litigation and compliance, and is a key participant in the department’s broad regulatory advisory work. Former senior counsel Rosa Fernanda Gómez left the firm in November 2024.
