Cassagne Abogados

Undoubtedly the foremost boutique in the administrative and public law segment, Cassagne Abogados is known not only for those specialisms but also its constitutional law and economic regulation expertise; it also has particular strength in complex litigation. Advising across a range of industries, areas of work include public contracts, infrastructure projects and arbitration. A case in point was its recent advisory to a construction consortium comprising Brazil’s Queiroz Galvão and Argentine company Rovella Carranza in their successful participation in a competitive tender for works on behalf of Buenos Aires’ water and drainage company with Agua y Saneamientos Argentinos (AySA). The team is co-led by founding partner Juan Carlos Cassagne (universally recognised as one of the sector’s finest exponents), along with the deeply experienced Máximo Fonrouge, Pablo Perrino, and the very active Ezequiel Cassagne – who led on the above mandate. The December 2021  promotion of Juan Pablo Martini and Juan Carlos Sanguinetti -experts in administrative law and administrative economic law, respectfully- has further deepened the bench, with Martini becoming head of the regulatory practice (particularly in relation to consumption), and Sanguinetti, head of the competition group. The promotions follow on from the earlier November-hire of administrative sanctioning expert Pablo Daniel Sanabria -who has particular expertise in the financial sector- as a partner.

Work highlights

  • Successfully advised a construction consortium comprising Queiroz Galvão and Rovella Carranza on participation in the competitive tender with Buenos Aires’ water and drainage company, Agua y Saneamientos Argentinos (AySA), for the $367m Emisario Berazategui works, to be funded by loans from the Banco Interamericano de Desarrollo (BID).
  • Successfully represented Asociación de Teleradiodifusoras Argentinas (ATA) in both the contentious administrative and federal courts with regard to the possibility of taking IVA into account in relation to the sums paid in employee charges; decisions subsequently ratified by the Supreme Court.
