Under the Act an enterprise is deemed to be dominant in a market if by itself or together with an interconnected company, it occupies such a position of economic strength as will enable it to operate in the market without effective constraints from its competitors or potential competitors. Being dominant is, in itself, not a breach of the Act, but when an enterprise abuses its dominant position, it breaches Sections 20 and 21 of the Act. Examples of abusive behavior include restricting the entry of any business or person into a market; imposing unfair buying or selling prices; and granting of preferential treatment to some customers over others.
