Philippi Prietocarrizosa Ferrero DU & Uria



Dispute resolution

The Peruvian office of Philippi Prietocarrizosa Ferrero DU & Uría is routinely involved in arbitration proceedings and commercial, civil and administrative disputes. The litigation group is particularly effective in infrastructure and regulation disputes, having represented the biggest telephone operator in Perú against a telecom regulatory agency. The firm’s clients range in size and sector – from a large mining company to a highway concessionaire.

Litigation star Ramiro Portocarrero has been involved in some of the country’s biggest energy regulation arbitration proceedings and continues to assist clients in international arbitration matters before the ICC. He successfully persuaded the Superior Court to vacate and annul an award that was favorable to the opposing party, GyM. The award would have forced the client, Empresa de Generación Eléctrica Machupicchu, to pay $13 million. Sebastian Basombrio is a litigator who emphasizes on judicial and arbitration conflicts related to commercial, contracts, energy and infrastructure disputes. Basombrio is routinely involved in national and international disputes, often engaging in numerous negotiations for high-profile clients. He has recently handled a COVID-19 related action, which suspended toll collection and overrode the compensation mechanisms stipulated in the contracts between the concessionaries and the Peruvian State. Basombrio represents both Autopista del Norte and Concesionaria Vial del Perú in the constitutional process and recently obtained an injunction suspending the application. Following the injunction, the Constitutional Tribunal declared the law unconstitutional.
