Under the Community's competition rules, a dominant position is such that a firm or group of firms would be in a position to behave to an appreciable extent independently of its competitors, customers and ultimately of its consumers (3). Such a position would usually arise when a firm or group of firms accounted for a large share of the supply in any given market, provided that other factors analysed in the assessment (such as entry barriers, customers' capacity to react, etc.) point in the same direction.
Po konkurenčnih pravilih Skupnosti gre za prevladujoč položaj, ko bi bilo podjetje ali skupina podjetij v položaju, da bi se v občutni meri obnašala neodvisno od svojih konkurentov, kupcev ali končno od svojih potrošnikov [3] Tak položaj se je ponavadi pojavil, ko je bilo podjetje ali skupina podjetij odgovorno za velik delež ponudbe na določenem trgu, pod pogojem, da drugi dejavniki, preučevani v presoji (kot so vstopne ovire, odziv potrošnikov) kažejo v isto smer.
