7 important questions on EU COMPETITION LAW - Article 102: Abuse of A Dominant Position - Element 2: Dominance

United Brands Co v Commission (case 27/76)

Dominance was defined in this case as "a position of economic strength enjoyed by an undertaking which enables it to prevent effective competition being maintained on the relevant market by giving it the power to behave to an appreciable extent independently of its competitors, customers, and ultimately of its consumers".

AKZO Chemie BV [1986] 3 CMLR 273, para 67

The power to exclude effective competition is not only being independent from competitive factors but may also involve the ability to eliminate or seriously weaken existing competitors or to prevent potential competitors from entering the market.

Europemballage Corp and Continental Can Co Inc v Commission (case 6/72)

A position can be dominant within the meaning of Article 102 only if it is dominant in a relevant market.

Thus, to access if an undertaking has sufficient economic strength to behave independently of, or even exclude, competitors, it is necessary to ascertain the relevant market in which competition is said to exist.
