When businesses restrict competition by agreeing to coordinate their market behavior instead of competing openly, this is harmful to consumers as well as other competitors. The task of the Antitrust Authority is to prevent this from happening and to inflict fines on whoever breaks the law. The Antitrust Authority also steps in whenever businesses abuse their market power by imposing unreasonable prices on consumers, denying market access to potential competitors or maneuvering to cut competitors out of their markets.

Whenever two companies merge or one company purchases another, the Antitrust Authority determines whether the new enterprise embodies too much market power. When threats to competition are identified, it may prohibit the merger or impose measures for mitigating their negative impact on competition.
