Competition/Antitrust | Latin America

Argentina

Competition/Antitrust covers the body of laws that prohibits anti-competitive behaviour (monopoly) and unfair business practices. This includes practices that hurt business, consumers, or both, or that generally violate standards of ethical behavior. Antitrust litigation and M&A-related competition work are both included in this section. Competition/Antitrust covers the body of laws prohibiting actions which restrict or limit free competition between economic agents both absolutely (through cartel activity) and relatively (through abuse of dominant position). In particular, the section focuses on merger control (filings before the relevant authorities), anti-competitive behaviour investigations and market studies carried out by authorities into the competitiveness of particular sectors. Litigation against the competent authorities is also considered here, as are civil claims initiated by economic agents seeking damages for anti-competitive behaviour.
