Arrieta Mantilla & Asociados

Commended for ‘the concreteness of its proposed strategies’, Arrieta Mantilla & Asociados combines arbitration expertise with the wider firm’s premier offerings in public law and projects to specialise in representing transport — particularly toll-road — concessionaires in contract disputes against government entities. The team is also active in the energy, mining and telecoms spheres. Department co-head Paula Andrea Ramos ’stands out for her professionalism’ and is representing Concesionaria Vial Andina (Coviandina) in a dispute against Colombia’s National Infrastructure Agency (ANI) focused on the recognition and payment of idle costs associated with delays caused by the Covid-19 pandemic. Fellow co-head Carlos Alberto Manzano is highlighted for his ‘assertiveness in investigating background information’; he is acting for Concesionaria Ruta del Cacao in an arbitration proceeding against ANI concerning responsibility for the costs of implementing a technical solution necessitated by geological instability inherent to the concession area. The group additionally benefits from a deep pool of experienced associates, including Juan Felipe Cornejo, who routinely appears before national arbitration tribunals; and dispute resolution-focused María Paula Saldarriaga, who arrived in February 2024 from Durán & Osorio Abogados Asociados.
