Within: Dispute resolution

M & M Bomchil has a prominent dispute resolution practice, which is highly sought after for its specialist expertise in economic regulation (particularly energy issues), administrative law and complex arbitration. Guido Tawil, who is widely regarded as a ‘powerhouse in contentious energy matters’, heads the arbitration department; he recently acted in conjunction with Francisco Gutiérrez, María Inés Corrá, counsel Rafael Mariano Manóvil and newly promoted partner Federico Campolieti to represent a major multinational company in arbitration proceedings (under ICC, UNCITRAL and domestic rules) brought by local subcontractors arising from a state contract terminated by the government. In another administrative law-related case, Tawil and Corrá are assisting several wheat mills with various claims against the government concerning the lack of compensation for commercialising flour in the domestic market at subsidised prices. Javier Petrantonio heads the litigation practice and spearheaded the team (which also comprised counsel Hugo Lafalce and senior associate Martín Torres Girotti) that represented Carrefour in four significant claims stemming from the acquisition of Argentine supermarket chains. The group has also recently undertaken work for Aeropuertos Argentina 2000, Peugeot Citroën and Siemens.
