Antitrust and Competition

The Firm’s Antitrust and Competition Practice has been steadily growing in the context of the recent Constitutional Reforms, first in Competition and Telecommunications (2013) and later in the Energy sector (2014), which were passed to aggressively open until-then monopolistic markets and create new business opportunities for local and global companies. Along with such opportunities, companies are facing unprecedented challenges in light of the creation of new and stronger regulators, hefty criminal, administrative and civil penalties and numerous statutes and regulations issued in the recent past. We are in a privileged position to assist our existing and potential clients seeking to take advantage of the newly increased business opportunities among abundant regulation and competition oversight.


Our Antitrust and Competition Practice Group has the capabilities and experience to provide legal counsel and representation to major public and private companies and investment funds in the Mexican market, including but not limited to the following:



- Merger control procedures, including requests for pre-merger approval and negotiation of remedies in domestic and multi-jurisdictional transactions.



- Identification of risks and preparation of mitigation protocols, including training to executives with high exposure in antitrust matters.



- Business practices, regulatory and contract review from a competition perspective, to identify and eliminate hurdles to efficient markets.



- Counseling and representation throughout investigation proceedings initiated by the Mexican Competition Commission, including cartel behavior, abuse of dominance and barriers to entry.



- Administrative litigation related with antitrust and competition matters before specialized courts.



- Compliance with the antitrust and competition legislation.



- Institutional approaches with the Mexican Antitrust Commission, as well as other relevant authorities with powers in competition matters, including the telecom agency (Ifetel) and energy upstream and midstream/ downstream regulators (CNH and CRE, respectively).

Arbitration and Mediation

Gonzalez Calvillo, S.C. offers seasoned and highly trained arbitrators, mediators, and other qualified Alternative Dispute Resolution (ADR) neutrals on any method of resolving controversies outside the traditional litigation process. We advise our clients on the use, convenience and feasibility of ADR techniques such as arbitration or mediation and we represent them in the corresponding proceedings. We also advise clients and attorneys on drafting arbitration and mediation clauses in contracts and similar documents when appropriate for our clients' objectives. ADR oftentimes represents a faster, less expensive and more confidential means of resolving controversies and interpretations. Another advantage of ADR is that a mediator can be selected by the parties for his or her specific experience, knowledge, and availability.


We have used ADR methods to resolve numerous disputes pre-litigation and, depending on the underlying business scenario, have encouraged the use of ADR clauses in the agreements. We have trained other arbitrators and mediators, and have presented seminars on several ADR topics. We originated the establishment of the most important mediation organization in Mexico, the Instituto Mexican de la Mediación, and lead in the writing of the original rules for the process. Today, the most visible and high-profile law firms in Mexico are members of the IMM and meet at least monthly to discuss ADR-related topics. Several partners of our firm, including our founding partner, are dedicated to ADR on a full-time basis and have been designated as arbitrators in landmark cases.


As part of our dispute resolution practice, we represent clients in domestic and international arbitration proceedings. Our arbitration experience, established in complex and challenging proceedings conducted before important institutions, enables us to offer highly specialized services. We also advise our clients in negotiations to prevent potential litigation. In addition to conducting complex negotiations or court representations, we are experienced in alternative dispute resolution methods such as mediation and conciliation in an effort to avoid unnecessary disputes and maximize beneficial and efficient results for clients.
