Santos y Ríos has one of Mexico's smaller competition practices, but size has not dented its prospects.

Competition practices fall into two categories in Mexico. There are the specialists with an incentive to run the full gamut of antitrust services, and there are the firms whose competition practices are in transition; although it originally suited them to handle the odd competition filing when driving through a deal, there is now sufficient impetus for the firms to offer all services and organise their specialists into a stand-alone team.

Cadwalader Wickersham & Taft’s antitrust practice underwent a complete overhaul last year. Its former team, including partners Steven Sunshine, Jess Biggio and the recently promoted Matthew Hendrickson, left en masse in January to join Skadden Arps. A new group was created in April. It is led by Who’s Who nominee Rick Rule, who joined from Fried Frank Harris Shriver & Jacobson.

Creel, García-Céullar, Aiza y Enríquez is the largest Mexican firm in the GCR 100, and a new entry this year. Its competition practice comprises two partners and three associates, and is led by Who's Who nominee Luis Gerardo Garcia and Jose Ruiz.
