The investigation in the traffic signalization materials market was concluded, which started with a leniency application claiming that there is a collusion in public tenders. At the end of the day, Turkish Competition Authority (TCA) did not impose any fine on the concerned undertakings, which is interesting, if not bizarre (!). Since accepting the leniency application should mean that the applicant had provided adequate evidence to prove an infringement. However, it seems that things did not quite turn out as anticipated for the TCA. We hope to see details about all of these considerations when the reasoned decision released.
