Ranked Individuals

The firm has a unique focus on the full spectrum of antitrust & competition matters, as well as a long tradition and experience. Since the enactment of the very first Greek Competition Act back in the late seventies, the proliferation of EC (now EU) rules and guidelines, the decentralization of EU antitrust enforcement, the changes in merger control and the development of EU state aid law, we have been at the forefront of specialized services in this field.
The importance of EU and Greek competition law has long been recognized by major domestic clients and international clients doing business in Greece. Competition authorities have significantly increased their powers and investigation activities, whereas private enforcement is gaining more and more attention. In addition to EU courts, the Greek administrative Judge plays an important role in shaping the interpretation of both substantive and procedural rules. We have the requisite in-depth legal knowledge, familiarity with regulatory authorities and market expertise to assist our clients in defining their strategies and navigating through this complex landscape.
