Prohibition of abuse of dominant position is a legal framework designed to prevent entities that hold a dominant market position from engaging in practices that could harm competitive conditions in the market, consumer interests, or economic freedom of other companies. This prohibition is a cornerstone of antitrust laws globally and is aimed at ensuring a level playing field in the marketplace.
Entities are considered dominant if they have significant market power that allows them to act independently of competitors, customers, or ultimately, consumers. The abuse can take various forms, such as imposing unfair purchase or selling prices, limiting production, markets, or technical development to the prejudice of consumers, or applying dissimilar conditions to equivalent transactions, thereby placing certain partners at a competitive disadvantage.
