ECIJA Colombia impresses with its ability to address matters both from an ‘analytical and in-depth‘ perspective and also in a ‘practical and strategic way’. The team’s ability to link into the global firm’s international network is another significant advantage and positions it as a good choice for multinational matters, evidenced by its recent advice to Discovery on the Colombian competition aspects of its acquisition of AT&T’s WarnerMedia business. It also routinely handles domestic merger reviews, competition litigation and behavioural work. Former SIC antitrust superintendent Pablo Márquez led the Discovery work and co-heads the department alongside Julio Castañeda. The team also includes talented counsel Pablo Onofre — who provided sole support on the Discovery case — as well as associates Diana Lucía Castiblanco and Jorge Mario González.

Colombia > TMT

ECIJA Colombia was formed through the May 2021 tie-up between legacy firm Márquez Barrera Castañeda Ramírez (MBCR) and Spain-headquartered TMT specialist ECIJA. Arguably best known for the strength of its media and entertainment law practice, the local office also packs a punch in regulatory matters regarding the telecoms, internet and e-commerce industries. The ‘friendly, competent and diligent‘ team is co-led by Patricia Renjifo -who specialises in IP, media and entertainment law- alongside regulatory specialist Pablo Márquez, who is a former chairman of Colombia’s Commission for Communications Regulation. Other key contacts include litigation and telecoms partner Julio Castañeda, of counsel Pablo Onofre, and senior associates Paula Gutiérrez de Piñeres and Andrés Paillié. Of counsel Victor Cuéllar Olarte left to become general counsel at EdgeUno in January 2022.

Colombia > Dispute resolution > Litigation

ECIJA Colombia has ‘unparalleled experience in regulatory and competition matters for the ICT sector‘, according to sources. Naturally, this formidable offering ensures a steady stream of competition-related litigation, but the group has also recently acted on litigation arising from consumer protection, directors’ liability and contractual disputes. Pablo Márquez  is an antitrust expert with a robust record in contentious competition matters; in a notable mandate, he is acting alongside antitrust, litigation and telecoms partner Julio Castañeda  to represent Conalvías Construcciones in one of the largest unfair competition lawsuits ever filed in Colombia, worth approximately $65m. Other key names include Camilo Ramírez Zuluaga  , who has a focus on private law litigation and arbitration, and supporting associate Nasser Obando .
