Colombia > Competition and antitrust Tier 2

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.
