This Special Issue aims to provide detailed insight into the contemporary approaches adopted by the Turkish Competition Board (“Board”), the decisional body of the Turkish Competition Authority (“Authority”) regarding anticompetitive agreements, unilateral conduct and mergers. The approaches adopted by the Board in its recent precedent are heavily influenced by global trends such as the close scrutiny over digital players as well as increasing attention towards competition law issues concerning labour markets. The substantive analysis regarding the anticompetitive agreements, unilateral conduct, and mergers has been shaped by Law No. 4054 on the Protection of Competition (“Law No. 4054”) as well as the secondary legislation. Further to Law No. 4054, there are several mechanisms for the Authority to focus on and to streamline certain of its processes, such as the use of the de minimis principle in its cases, “significant impediment of effective competition” (“SIEC”) test for merger control, behavioural and structural remedies for anti-competitive conducts, and procedural tools including leniency, commitment and settlement mechanisms. The articles within this Special Issue aim to reveal and explain the evolving efforts of the Board in establishing its case law in light of the amendments to the main and secondary legislation by way of also following global trends, as well as taking advantage of the well-established practices under the EU competition law regime in recent years, on various fronts.
