Abuse of dominant position bars firms from imposing unfair conditions, predatory pricing, or denying market access. The statute prohibits enterprises or groups from abusing a dominant position by imposing unfair or discriminatory conditions or prices (including predatory price), limiting production or technical development, denying market access, conditioning contracts on unrelated supplementary obligations, or using dominance in one market to enter or protect another. Dominant position is defined as the ability to operate independently of competitive forces or to affect competitors, consumers, or the market; predatory price is pricing below cost with intent to reduce competition.
