An extract from The Dominance and Monopolies Review - 7th edition


i Overview

As mentioned above, the definition of abuse is not provided under Article 6. Although Article 6 does not define what constitutes 'abuse' per se, it provides five examples of prohibited abusive behaviour, which forms a non-exhaustive list, and falls to some extent in line with Article 102 of the TFEU. These examples are as follows:

  1. directly or indirectly preventing entry into the market or hindering competitor activity in the market;
  2. directly or indirectly engaging in discriminatory behaviour by applying dissimilar conditions to equivalent transactions with similar trading parties;
  3. making the conclusion of contracts subject to acceptance by the other parties of restrictions concerning resale conditions, such as:
    • the purchase of other goods and services;
    • acceptance by intermediary purchasers of the display of other goods and services; or
    • maintenance of a minimum resale price;
  4. distorting competition in other markets by taking advantage of financial, technological and commercial superiorities in the dominated market; and
  5. limiting production, markets or technical development to the prejudice of consumers.

Moreover, Article 2 of Law No. 4054 adopts an effects-based approach for identifying anticompetitive conduct, with the result that the determining factor in assessing whether a practice amounts to an abuse is the effect on the market, regardless of the type of the conduct at issue. Notably, the concept of abuse covers exploitative, exclusionary and discriminatory practices. Theoretically, a causal link must be shown between dominance and abuse. The Competition Board does not yet apply a stringent test of causality, and it has in the past inferred abuse from the same set of circumstantial evidence that was employed in demonstrating the existence of dominance. Further, abusive conduct on a market that is different from the market subject to a dominant position is also prohibited under Article 6. On the other hand, previous precedents show that the Competition Board is yet to review any allegation of other forms of abuse, such as:

  1. strategic capacity construction;
  2. predatory product design or product innovation;
  3. failure to pre-disclose new technology;
  4. predatory advertising; or
  5. excessive product differentiation.
ii Exclusionary abusesExclusionary pricing

Predatory pricing may amount to a form of abuse, as evidenced by many precedents of the Competition Board. That said, complaints on this basis are frequently dismissed by the Competition Authority owing to its welcome reluctance to micromanage pricing behaviour. High standards are usually observed for bringing forward predatory pricing claims. Nonetheless, in the UN Ro-Ro case, UN Ro-Ro was found to abuse its dominant position through predatory pricing and faced administrative monetary fines.

Further, in line with EU jurisprudence, price squeezes may amount to a form of abuse in Turkey, and recent precedents involved an imposition of monetary fines on the basis of price squeezing. The Competition Board is known to closely scrutinise price-squeezing allegations.

Exclusive dealing

Although exclusive dealing, non-compete provisions and single branding normally fall within the scope of Article 4 of Law No. 4054, which governs restrictive agreements, concerted practices and decisions of trade associations, such practices could also be raised within the context of Article 6.

On a separate note, Block Exemption Communiqué No. 2002/2 on Vertical Agreements no longer exempts exclusive vertical supply agreements of an undertaking holding a market share of above 40 per cent. Therefore, a dominant undertaking is an unlikely candidate to engage in non-compete provisions and single-branding arrangements.

Additionally, although Article 6 does not explicitly refer to rebate schemes as a specific form of abuse, rebate schemes may also be deemed to constitute a form of abusive behaviour. In Turkcell, the Competition Board condemned the defendant for abusing its dominance by, inter alia, applying rebate schemes to encourage the use of the Turkcell logo and refusing to offer rebates to buyers that work with its competitors. The Competition Board also condemned Doğan Yayın Holding for abusing its dominant position in the market for advertisement spaces in the daily newspapers by applying loyalty-inducing rebate schemes. In 2017, the Competition Board fined Luxottica for its activities in the wholesale of branded sunglasses by obstructing competitors' activities through its rebate systems.


Tying and leveraging are among the specific forms of abuse listed in Article 6. The Competition Board has assessed many tying, bundling and leveraging allegations against dominant undertakings, and has ordered certain behavioural remedies against incumbent telephone and internet operators in some cases, to make them avoid tying and leveraging.

Refusal to deal

Refusal to deal and grant access to essential facilities are forms of abuse that are frequently brought before the Competition Authority, and there have been various decisions by the Competition Board concerning these matters.

iii Discrimination

Both price and non-price discrimination may amount to abusive conduct under Article 6. The Competition Board has in the past found incumbent undertakings to have infringed Article 6 by engaging in discriminatory behaviour concerning prices and other trade conditions.

iv Exploitative abuses

Exploitative prices or terms of supply may be deemed to be an infringement of Article 6, although the wording of the law does not contain a specific reference to this concept. The Competition Board has condemned excessive or exploitative pricing by dominant firms. That said, complaints on this basis are frequently dismissed by the Competition Authority because of its above-mentioned reluctance to micromanage pricing behaviour.
