I Introduction

The main legislation applying specifically to the behaviour of dominant firms is Article 6 of Law No. 4054 on the Protection of Competition (Law No. 4054). It provides that ‘any abuse on the part of one or more undertakings individually or through joint venture agreements or practices, of a dominant position in a market for goods or services within the whole or part of the country is unlawful and prohibited'.

Pursuant to Article 6, the abusive exploitation of a dominant market position is prohibited in general. Therefore, the Article 6 prohibition applies only to dominant undertakings, and in a similar fashion to Article 102 of the Treaty on the Functioning of the European Union (TFEU), dominance itself is not prohibited, but only the abuse of dominance is outlawed. Further, Article 6 does not penalise an undertaking that has captured a dominant share of the market because of superior performance.

Dominance provisions as well as the other provisions of Law No. 4054 apply to all companies and individuals, to the extent that they act as an ‘undertaking' within the meaning of Law No. 4054. An ‘undertaking' is defined as a single integrated economic unit capable of acting independently in the market to produce, market or sell goods and services. Law No. 4054 therefore applies to individuals and corporations alike, if they act as an undertaking. State-owned and state-affiliated entities also fall within the scope of the application of Article 6.2

Furthermore, Law No. 4054 does not recognise any industry-specific abuses or defences; therefore certain sectoral independent authorities have competence to regulate certain activities of dominant players in the relevant sectors. For instance, according to the secondary legislation issued by the Turkish Information and Telecommunication Technologies Authority, firms with a significant market share are prohibited from engaging in discriminatory behaviour among companies seeking access to their network, and unless justified, rejecting requests for access, interconnection or facility sharing. Similar restrictions and requirements are also applicable in the energy sector. The sector-specific rules and regulations bring about structural market remedies for the effective functioning of the free market. They do not imply any dominance-control mechanisms. The Turkish Competition Authority (the Competition Authority) is the only regulatory body that investigates and condemns abuses of dominance.

On a different note, structural changes through which an undertaking attempts to establish dominance or strengthen its dominant position (for instance in cases of acquisitions) are regulated by the merger control rules established under Article 7 of Law No. 4054. Nevertheless, a mere demonstration of post-transaction dominance in itself is not sufficient for enforcement under the Turkish merger control rules, but rather ‘a restriction of effective competition' element is required to deem the relevant transaction as illegal and prohibited. Thus, the principles laid down in merger decisions can also be applied to cases involving the abuse of dominance. For instance, recently the Turkish Competition Board (the Competition Board) rejected the acquisition of sole control over Beta Turizm and Pendik Turizm by Setur as it concluded that the transaction would result in the creation of a dominant position and thus, would impede effective competition.3

On a separate note, mergers and acquisitions are normally caught by the merger control rules contained in Article 7 of Law No. 4054. However, there have been cases, albeit rarely, where the Competition Board found structural abuses through which dominant firms used joint venture agreements as a back-up tool to exclude competitors, which is prohibited under Article 6.4

II Year in Review

According to the Competition Authority's 2016 statistics, the Competition Board decided on 41 pre-investigations or investigations out of a total of 83, on the basis of allegations regarding violations of Article 4 of Law No. 4054, which prohibits all agreements between undertakings, decisions by associations of undertakings and concerted practices that have (or may have) as their object or effect the prevention, restriction or distortion of competition within a Turkish product or services market or a part of thereof. Further, 29 finalised investigations have been carried out on the basis of allegations regarding violation of Article 6 of Law No. 4054, which prohibits any abuse on the part of one or more undertakings, individually or through joint agreements or practices, of a dominant position in a market for goods or services within the whole or part of the country. The Competition Board also decided on the remaining 13 investigations that have been initiated on the basis of both Article 4 and Article 6 concerns. Accordingly, it would be justified to assert that cooperative offences, referring to both horizontal and vertical arrangements, continue to be the area of heaviest enforcement under Turkish competition law.5

Over the past five years, the Competition Board has shifted its focus from merger control cases to concentrate more on the fight against cartels and cases of abuse of dominance. As a reflection of this trend, the Competition Board has also shown an increased interest in the unilateral pricing behaviour of undertakings, as exemplified by recent high-profile predatory pricing investigations involving Turkish Airlines,6 where there was ultimately no finding of an abuse of a dominant position, and the shipping company UN Ro-Ro,7 where UN Ro-Ro was fined 4 per cent of its 2011 turnover, which amounted to 841,199.70 lira. In Turkcell,8 the Competition Board analysed the market foreclosure allegations against Turkcell, Turkey's dominant GSM operator. It concluded that Turkcell had violated the law by preventing its competitors' activities through exclusive practices for vehicle-tracking services, imposing a monetary fine of 39 million lira. Tüpraş9 was fined more than 412 million lira for the abuse of its dominant position through excessive pricing; the Competition Authority had launched the investigation in 2012. Similarly Mey İçki10 was fined more than 155 million lira for abusing its dominance position by way of aggravating its competitors activities. In Türk Telekom,11 the undertaking was fined approximately 33 million lira for abusing its dominance through delaying, aggravating and obstructing facility-sharing request applications made by third parties.

The following table shows the Competition Board's most recent landmark decisions regarding abuse of dominance:

Yemek Sepeti

No. 16-20/347-156, 9 June 2016

A noteworthy case regarding the abuse of dominant position was concerned with MFC (most favoured customer) practices of Yemek Sepeti, an online food ordering platform. Accordingly, the Competition Board reviewed Yemek Sepeti's MFC clauses that were being applied to the restaurants in its system. The Competition Board decided that Yemek Sepeti was in a dominant position since it was the first entrant of the market and it was protecting its market power with high entry barriers. The Competition Board took into consideration different antitrust authorities' approaches in other jurisdictions (e.g., the USA, EU, UK and Germany) and stated that MFC clauses could be interpreted as an anticompetitive behaviour. The two-sided market structure and network effects were also taken into account by the Competition Board when assessing effects of MFC practices. The Competition Board decided that all Yemek Sepeti's MFC practices, which are preventing competitor platforms from offering better/different sale conditions, were abusive and imposed administrative fine of approximately 428,000 lira to the undertaking. The Board also ordered that Yemek Sepeti should change its existing agreements in accordance with the decision.

Approximately 428,000 lira

Türk Telekom

No. 16-20/326-146, 9 June 2016

The incumbent operator of Turkey (i.e. Türk Telekom) was subject to the Board's investigation owing to allegations of its practices concerning facility-sharing requests made by competitor. Widespread infrastructure of Türk Telekom and regulatory conditions were the main criteria behind the Competition Board's reasoning on establishing that Türk Telekom is in the dominant position in the relevant market. The characteristic of the market makes accessing to infrastructure indispensable for the alternative operators since the regulations envisage an application for facility sharing for the undertakings.

In this regard, the Competition Board considered eight of the alleged practices as refusal to supply conduct that generally resulted to delayed or overpriced facility-sharing activities. Against this background, the Competition Board decided that Türk Telekom abused its dominant position (Article 6 of Law No. 4054) through refusal to supply and imposed approximately 34 million lira fine on the undertaking at 0.45 per cent of its 2015 turnover. This decision re-emphasised the Board's stance on the abusive refusal to supply conduct.

Approximately 34 million lira


No. 16-10/159-70, 16 March 2016

Upon the complaint of a distributors' association, the Board launched a preliminary investigation against TÜPRAŞ, scrutinising its rebate system.

The Board defined the relevant product market as the ‘fuel wholesale market' and, without conducting an analysis on dominance, it concluded that TÜPRAŞ is in a dominant position within the relevant market based on the previous Board decisions.

The Board's foregoing TÜPRAŞ decision sets out significant parameters and considerations for the application of turnover premium rebate systems by undertakings in a dominant position. Indeed, pursuant to the Board's assessment, the turnover premium systems that are not personalised but standard targeted, transparent, granted to all customers under equal terms and objective amounts and where economies of scale are taken into consideration along with the balance of non-discrimination among the undertakings active in the relevant market, are considered to be in line with Law No. 4054. Consequently, the Board concluded that Solgar did not violate Law No. 4054, and, thus, it did not impose any administrative monetary fine on TÜPRAŞ.

III Market Definition and Market Power

The definition of dominance can be found in Article 3 of Law No. 4054, which states that ‘the power of one or more undertakings in a certain market to determine economic parameters such as price, output, supply and distribution independently from competitors and customers'. Enforcement trends show that the Competition Board is inclined to broaden the scope of application of the Article 6 prohibition by diluting the ‘independence from competitors and customers' element of the definition to infer dominance even in cases where clear dependence or interdependence between either competitors or customers exists.12

When unilateral conduct is in question, dominance in a market is the primary condition for the application of the prohibition stipulated in Article 6. For establishing a dominant position, first, the relevant market has to be defined and secondly, the market position has to be determined. The relevant product market includes all goods or services that are substitutable from a customer's point of view. The Guideline on Market Definition considers demand-side substitution as the primary standpoint of market definition. Thus, the undertakings concerned have to be in a dominant position in relevant markets, which are to be determined for every individual case and circumstance. Under Turkish competition law, the market share of an undertaking is the primary step for evaluating its position in the market. In theory, there is no market share threshold above which an undertaking will be presumed to be dominant. On the other hand, subject to exceptions, an undertaking with a market share of 40 per cent is a likely candidate for dominance, whereas a firm with a market share of less than 25 per cent would not generally be considered as dominant.

In assessing dominance, although the Competition Board considers a large market share as the most indicative factor of dominance, it also takes account of other factors such as legal or economic barriers to entry, portfolio power and financial power of the incumbent firm. Thus, domination of a given market cannot be solely defined on the basis of the market share held by an undertaking or of other quantitative elements; other market conditions as well as the overall structure of the relevant market should also be assessed in detail.

Collective dominance is also covered by Article 6. On the other hand, precedents concerning collective dominance are not mature enough to allow for a clear inference of a set of minimum conditions under which collective dominance should be alleged. That said, the Competition Board has considered it necessary to establish an economic link for a finding of abuse of collective dominance.13

Being closely modelled on Article 102 of the TFEU, Article 6 of Law No. 4054 is theoretically designed to apply to unilateral conduct of dominant firms only. When unilateral conduct is in question, dominance in a market is a condition precedent to the application of the prohibition laid down in Article 6. In practice, however, the indications show that the Competition Board is increasingly and alarmingly inclined to assume that purely unilateral conduct of a non-dominant firm in a vertical supply relationship could be interpreted as giving rise to an infringement of Article 4, which deals with restrictive agreements. With a novel interpretation, by way of asserting that a vertical relationship entails an implied consent on the part of the buyer, and that this allows Article 4 enforcement against a ‘discriminatory practice of even a non-dominant undertaking' or ‘refusal to deal of even a non-dominant undertaking' under Article 4, the Competition Board has in the past attempted to condemn unilateral conduct that should not normally be prohibited since it is not engaged in by a dominant firm. Owing to this peculiar concept (i.e., Article 4 enforcement becoming a fall-back to Article 6 enforcement if the entity engaging in unilateral conduct is not dominant), certain unilateral conduct that can only be subject to Article 6 enforcement (i.e., as if the engaging entity were dominant) has been reviewed under Article 4 (restrictive agreement rules). The 3M Turkey, Turkcell and Solgar decisions are the latest examples of this same trend. In 3M Turkey,14 the Competition Board analysed whether 3M Turkey, which was not found to be in a dominant position in the work safety products market, discriminated against some of its dealers under Article 4 and not under Article 6. 3M Turkey was cleared without a fine. In Turkcell,15 the Competition Board assessed whether Turkcell's exclusive contracts foreclosed the market, based on both Article 6 and Article 4, eventually finding that Turkcell did not violate either Article 6 or Article 4. Likewise, in Solgar,16 the Competition Board decided on a fully fledged investigation against Solgar, which looked into whether Solgar had violated Article 4 or Article 6 of Law No. 4054 by refusing to supply. The Competition Board concluded that Solgar did not violate Law No. 4054 and, thus, it did not impose any administrative monetary fine on Solgar. In Efes,17 the Competition Board assessed the allegations asserted towards Efes under Articles 4 and 6 of Law No. 4054 and decided that preventing the competitor undertaking from placing refrigerated cabinets at certain sales points does not obstruct the sales of the relevant competotors' products at the sales points in question and, therefore, does not give rise to de facto exclusivity. In light of the foregoing, the Competition Board ultimately did not initiate a full-fledged investigation.

IV Abuse

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 comes as a non-exhaustive list, and falls to some extent in line with Article 102 of the TFEU. Accordingly, these examples include the following:

  • a directly or indirectly preventing entry into the market or hindering competitor activity in the market;
  • b directly or indirectly engaging in discriminatory behaviour by applying dissimilar conditions to equivalent transactions with similar trading parties;
  • c 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, or acceptance by the intermediary purchasers of displaying other goods and services or maintenance of a minimum resale price;
  • d distorting competition in other markets by taking advantage of financial, technological and commercial superiorities in the dominated market; and
  • e 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. Furthermore, abusive conduct on a market that is different from the market subject to dominant position is also prohibited under Article 6.18 On the other hand, previous precedents show that the Competition Board is yet to review any allegation of other forms of abuse, such as strategic capacity construction, predatory product design or product innovation, failure to pre-disclose new technology, predatory advertising or excessive product differentiation.

ii Exclusionary abuses
Exclusionary pricing

Predatory pricing may amount to a form of abuse, as evidenced by many precedents of the Competition Board.19 That said, complaints on this basis are frequently dismissed by the Competition Authority due to its welcome reluctance to micro-manage 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.20

Furthermore, in line with the 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.21

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 6.22

On a separate note, the Block Exemption Communiqué No. 2002/2 on Vertical Agreements no longer exempts exclusive vertical supply agreements of an undertaking holding a market share above 40 per cent. Thus, 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. The Competition Board, in Turkcell,23 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 has 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.24


Tying and leveraging are among the specific forms of abuse listed in Article 6. The Competition Board 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 have them avoid tying and leveraging.25

Refusal to deal

Refusals to deal and access to essential facilities are the forms of abuses that are brought before the Competition Authority frequently. Therefore, there are various decisions by the Competition Board concerning this matter.26

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.27

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 Board has condemned excessive or exploitative pricing by dominant firms.28 That said, complaints on this basis are frequently dismissed by the Competition Authority because of its welcome reluctance to micromanage pricing behaviour.

V Remedies and Sanctions

i Sanctions

The sanctions that could be imposed for abuses of dominance under Law No. 4054 are administrative in nature. In the case of a proven abuse of dominance, the incumbent undertakings concerned shall be (separately) subject to fines of up to 10 per cent of their Turkish turnover generated in the financial year preceding the date of the fining decision (if this is not calculable, the turnover generated in the financial year nearest to the date of the fining decision will be taken into account). Employees or members of the executive bodies of the undertakings or association of undertakings (or both) that had a determining effect on the creation of the violation are also fined up to 5 per cent of the fine imposed on the undertaking or association of the undertaking. After the amendments in 2008, the new version of Law No. 4054 makes reference to Article 17 of the Law on Minor Offences to require the Competition Board to take into consideration factors such as the level of fault and amount of possible damage in the relevant market, the market power of the undertakings within the relevant market, duration and recurrence of the infringement, cooperation or driving role of the undertakings in the infringement, financial power of the undertakings, compliance with the commitments, etc., in determining the magnitude of the monetary fine.

Additionally, Article 56 of Law No. 4054 provides that agreements and decisions of trade associations that infringe Article 4 are invalid and unenforceable with all their consequences. The issue of whether the ‘null and void' status applicable to agreements that fall foul of Article 4 may be interpreted to extend to cover contracts entered into by infringing dominant companies is a matter of ongoing controversy. However, contracts that give way to or serve as a vehicle for an abusive contract may be deemed invalid and unenforceable because of violation of Article 6.

The highest fine imposed to date in relation to abuse of a dominant position was in Tüpraş,29 where Tüpraş incurred an administrative fine of 412 million lira (equal to 1 per cent of the relevant undertaking's annual turnover for the relevant year).

In addition to monetary sanctions, the Competition Board is authorised to take all necessary measures to terminate infringements, to remove all de facto and legal consequences of every action that has been taken unlawfully, and to take all other necessary measures to restore the level of competition and status as before the infringement.

ii Behavioural and structural remedies

Law No. 4054 authorises the Competition Board to take interim measures until the final resolution on the matter, in case there is a possibility of serious and irreparable damages.

Articles 9 and 27 of Law No. 4054 entitle the Competition Board to order structural or behavioural remedies (i.e., require undertakings to follow a certain method of conduct such as granting access, supplying goods or services or concluding a contract). Failure by a dominant firm to meet the requirements so ordered by the Competition Board would lead to an investigation, which may or may not result in a finding of infringement. The legislation does not explicitly empower the Competition Board to demand performance of a specific obligation such as granting access, supplying goods or services or concluding a contract through a court order.

VI Procedure

The Competition Board is entitled to launch an investigation into an alleged abuse of dominance ex officio or in response to a complaint. In the event of a complaint, the Competition Board rejects the notice or complaint if it deems it not to be serious. Any notice or complaint is deemed rejected if the Competition Board remains silent for 60 days. The Competition Board decides to conduct a pre-investigation if it finds the notice or complaint to be serious. At this preliminary stage, unless there is a dawn raid, the undertakings concerned are not notified that they are under investigation. Dawn raids (unannounced on-site inspections) and other investigatory tools (e.g., formal information request letters) are used during this pre-investigation process. The preliminary report of the Competition Authority experts will be submitted to the Competition Board within 30 days of a pre-investigation decision being taken by the Competition Board. It will then decide within 10 days whether to launch a formal investigation. If the Competition Board decides to initiate an investigation, it will send a notice to the undertakings concerned within 15 days. The investigation will be completed within six months. If deemed necessary, this period may be extended, once only, for an additional period of up to six months, by the Competition Board.

The investigated undertakings have 30 calendar days as of the formal service of the notice to prepare and submit their first written defences. Subsequently, the main investigation report is issued by the Competition Authority. Once the main investigation report is served on the defendants, they have 30 calendar days to respond, extendable for a further 30 days (second written defence). The investigation committee will then have 15 days to prepare an opinion concerning the second written defence. The defending parties will have another 30 days to reply to the additional opinion (third written defence). When the parties' responses to the additional opinion are served on the Competition Authority, the investigation process will be completed (the written phase of investigation involving claim or defence exchange will close with the submission of the third written defence). An oral hearing may be held ex officio or upon request by the parties. Oral hearings are held within at least 30 and at most 60 days following the completion of the investigation process under the provisions of Communiqué No. 2010/2 on Oral Hearings Before the Competition Board. The Competition Board will render its final decision within 15 calendar days of the hearing if an oral hearing is held, or within 30 calendar days of completion of the investigation process if no oral hearing is held. The appeal case must be brought within 60 calendar days of the official service of the reasoned decision. It usually takes around three to four months (from the announcement of the final decision) for the Competition Board to serve a reasoned decision on the counterparty.

The Competition Board may request all information it deems necessary from all public institutions and organisations, undertakings and trade associations. Officials of these bodies, undertakings and trade associations are obliged to provide the necessary information within the period fixed by the Competition Board. Failure to comply with a decision ordering the production of information may lead to the imposition of a turnover-based fine of 0.1 per cent of the turnover generated in the financial year preceding the date of the fining decision (if this is not calculable, the turnover generated in the financial year nearest to the date of the fining decision will be taken into account). The minimum fine for 2017 is 18,377 lira. Where incorrect or incomplete information has been provided in response to a request for information, the same penalty may be imposed. Recently, the Competition Board imposed a monetary fine of 7,551,953.95 lira on Türk Telekom for providing false or misleading information or documents within an investigation conducted on Türk Telekom and TTNet to determine whether their pricing behaviour violated Article 6 of Law No. 4054.30

Article 15 of Law No. 4054 also authorises the Competition Board to conduct on-site investigations. Accordingly, the Competition Board can examine the books, paperwork and documents of undertakings and trade associations, and, if need be, take copies of the same; request undertakings and trade associations to provide written or verbal explanations on specific topics; and conduct on-site investigations with regard to any asset of an undertaking. Law No. 4054 therefore provides broad authority to the Competition Authority on dawn raids. A judicial authorisation is obtained by the Competition Board only if the subject undertaking refuses to allow the dawn raid. Computer records are fully examined by the experts of the Competition Authority, including deleted items.

Officials conducting an on-site investigation need to be in possession of a deed of authorisation from the Competition Board. The deed of authorisation must specify the subject matter and purpose of the investigation. The inspectors are not entitled to exercise their investigative powers (copying records, recording statements by company staff, etc.) in relation to matters that do not fall within the scope of the investigation (i.e., that which is written on the deed of authorisation). Refusal to grant the staff of the Competition Authority access to business premises may lead to the imposition of a fixed fine of 0.5 per cent of the turnover generated in the financial year preceding the date of the fining decision (if this is not calculable, the turnover generated in the financial year nearest to the date of the fining decision will be taken into account). The minimum fine for 2017 is 18,377 lira. It may also lead to the imposition of a periodic daily-based fine of 0.05 per cent of the turnover generated in the financial year preceding the date of the fining decision (if this is not calculable, the turnover generated in the financial year nearest to the date of the fining decision will be taken into account) for each day of the violation.

Final decisions of the Competition Board, including its decisions on interim measures and fines, can be submitted to judicial review before the Administrative Courts by filing a lawsuit within 60 days of the receipt by the concerned parties of the Competition Board's reasoned decision. Filing an administrative action does not automatically stay the execution of the Competition Board's decision (Article 27, Administrative Procedural Law).

After the recent legislative changes, administrative litigation cases (private litigation cases as well) are now subject to judicial review before the newly established regional courts (appellate courts), creating a three-level appellate court system consisting of administrative courts, regional courts and the Council of State (the court of appeals for private cases). The regional courts will (1) go through the case file both on procedural and substantive grounds and (2) investigate the case file and make their decision considering the merits of the case. The regional courts' decisions will be considered as final in nature. The decision of the regional court will be subject to the Council of State's review in exceptional circumstances, which are set forth in Article 46 of the Administrative Procedure Law. In such cases, the decision of the regional court will not be considered as a final decision and the Council of State may decide to uphold or reverse the regional court's decision. If the decision is reversed by the Council of State, it will be returned to the deciding regional court, which will in turn issue a new decision which takes into account the Council of State's decision. As the regional courts are newly established, it has not been experienced yet how long it takes for a regional court to finalise its review on a file. Accordingly, the Council of State's review period (for a regional court's decision) within the new system should also be tested before providing an estimate time period.

Third parties can also challenge the Competition Board's decision before the competent judicial tribunal, subject to the condition that they prove their legitimate interest.

VII Private Enforcement

A dominance matter is primarily adjudicated by the Competition Board. Enforcement is also supplemented with private lawsuits. Article 57 et seq. of Law No. 4054 entitle any persons who are injured in their business or property by reason of anything forbidden in the antitrust laws to sue the violators to recover up to three times their personal damages plus litigation costs and legal fees. Therefore, Turkey is one of the few jurisdictions in which a treble damages clause exists in the law. In private suits, incumbent firms are adjudicated before regular courts. Because the treble damages clause allows litigants to obtain three times their losses as compensation, private antitrust litigations are increasingly making their presence felt in the Article 6 enforcement arena. Most courts wait for the decision of the Competition Board, and form their own decision based on that decision. The majority of private lawsuits in Turkish antitrust enforcement rely on refusal to supply allegations.

VIII Future Developments

In 2013, the Competition Authority prepared the Draft Competition Law (the Draft Law). In 2015, the Draft Law was under discussion in the Turkish parliament's Industry, Trade, Energy, Natural Sources and Information Technologies Commission. The Draft Law proposed various changes to the current legislation; in particular, to provide efficiency in time and resource allocation in terms of procedures set out under the current legislation. The Draft Law became obsolete as a result of the general elections in June 2015. The Competition Authority has requested the re-initiation of the legislative procedure concerning the Draft Law, as noted in the 2015 Annual Report of the Competition Authority. It is further indicated that the Authority may take steps toward the amendment of certain articles if a new competition law is not passed by the parliament.

The Competition Authority also showed increasing willingness at the beginning of 2015 to develop its relations with other governmental agencies in Turkey, signing a cooperation protocol with the Energy Market Regulatory Authority and enlarging the scope of its cooperation protocol with the Information and Communication Technologies Authority.

The recent enforcement trend of the Competition Authority showed that the Authority is becoming more and more interested in the refusals to supply/contract of dominant undertakings. There have been several pre-investigations and investigations launched by the Competition Authority in relation to this aspect of the competition law principles in Turkey over the past year. These instances include the Competition Board's Ankara Uluslararası Kongre ve Fuar İşletmeciliği31 and Türk Telekomünikasyon32 decisions. Other high-profile cases involving abuse of dominance allegations in the past year are Yemeksepeti33 and Türk Eczacıları Birliği.34 In Yemeksepeti (an online meal order platform), the Board concluded that the use of most favoured customer clauses violated Article 6 of the Law No. 4054 since these clauses gave rise to exclusionary effects in the relevant market. In Türk Eczacıları Birliği, the Board decided that the agreements executed with the pharmaceutical suppliers that contain exclusivity clauses violated Article 6 of Law No. 4054.
