Legal 500 highlights Guerrero Ruiz | Legal as a “Firm to Watch” in Public Law and Regulation
Bogotá, October 2025. — The international publication The Legal 500 included Guerrero Ruiz | Legal in its 2026 edition as a “Firm to Watch” , highlighting the relaunch of the firm and the career of its founding partner, Gustavo Guerrero Ruiz , former Deputy Attorney General for Environmental, Mining-Energy and Agricultural Affairs of Colombia.
In its editorial commentary, Legal 500 noted:
"A former deputy prosecutor for environmental, mining, energy and agrarian matters, Gustavo Guerrero relaunched his boutique Guerrero Ruiz | Legal in September 2025, offering specialist public law advisory for the regulated sector. Guerrero, a 30-year veteran with expertise in public law, regulation, litigation and corporate matters, has deep expertise across the extractive industries, energy, infrastructure, agro-industry, urban matters and public services and environmental regulation."
This recognition consolidates Guerrero Ruiz | Legal 's projection as a boutique law and public affairs firm in regulated sectors , the result of more than three decades of combined experience in professional practice, public service and corporate advice.
The firm, previously recognized by Legal 500 (2022) in the practice of Environmental Law , now reaffirms its commitment to technical excellence, integrity and strategic advice to companies, associations and public entities that operate in the environmental, mining-energy, agricultural, urban, infrastructure and public services sectors.
