Lauded as 'truly expert in compliance and white-collar investigations work', the team of 'experts in the field' at boutique firm Libera Iuris (formerly LEC, Litigio Estratégico y Compliance, S.C.) is equipped to guide clients through the complexities of Mexican regulations in their daily operations. The group regularly handles matters related to anti-bribery, anti-corruption, AML, internal investigations, and data protection and cybersecurity. Following the August 2025 departure of ex-practice co-head Daniela Ortega Sosa, the group is led by the dual-qualified (Mexico / New York) Luis Dantón Martínez, who -in particular- frequently advises on Foreign Corrupt Practices Act matters; noted for his 'experience and track record', he also handles investigations, white collar-cases, anti-corruption and criminal litigation. 'Insightful and business-minded' senior associate José Antonio Sosa García joined the firm in August 2024 from Citi and specialises in constitutional, administrative, civil and criminal litigation, along with investigations, anti-corruption, AML and corporate governance.
