Dispute resolution in Paraguay

Moreno Ruffinelli & Asociados

Moreno Ruffinelli & Asociados' dispute resolution team is frequently instructed by some of Paraguay's leading companies in a range of areas, with recent cases involving companies operating in the agribusiness, automotive and construction sectors. While the practice primarily acts in domestic matters, a number of its recent highlights have involved cross-border elements and required such expertise, with Diego Moreno's representation of Andopar, local distributor of Pirelli tyres, in a lawsuit against Pirelli being representative of the firm's work in that respect. José Moreno Ruffineli is a key figure in the field and the arbitrator and experienced litigator heads the practice with Roberto Moreno, the Paraguayan arbitrator in the Court of Arbitration for Sport. Carlos Ruffinelli's practice focuses on corporate disputes, alternative dispute resolution and contentious matters in aviation law. He also has noted expertise in distribution claims and maritime law. Senior associate Alfredo Gonzalez Palacios stands out for his support on a number of the team's major cases in 2020.
