Cassagne Abogados

Public law Tier 1

Regulatory law powerhouse Cassagne Abogados is widely lauded as a ‘go-to firm for public law issues’, particularly on the contentious side due to its ‘unrivalled expertise in complex litigation’. The boutique firm’s specialist focus on administrative law, economic regulation and constitutional law continues to pay dividends, and it remains a popular choice for domestic and multinational companies looking for support on high-stakes matters. On the contentious front, Máximo Fonrouge recently acted alongside Julio Duran to represent Telefónica de Argentina in its action against the Argentine government – and the regulatory agency – challenging a spectrum award decision. On the non-contentious side, high-profile sector specialist Juan Carlos Cassagne teamed up with Ezequiel Cassagne and Pablo Perrino to act for Boldt in the public tender process by Buenos Aires for the provision of slot machines. Other representative clients include Aerolíneas Argentinas, British American Tobacco and China Gezhouba Group. In a notable recent addition, the firm hired new associate and PPP specialist María Soledad Vallejos Meana, who joins from the Ministry of Finance.
