Peter Alexiadis is the founding partner of the Brussels office of Gibson, Dunn & Crutcher and he also serves as Partner-In-Charge of the office. He has practised Community law in Brussels since 1989, where his practice is split between competition law, communications policy, and intellectual property law. He is the holder of postgraduate legal qualifications from the Universities of London, Sydney and Thessaloniki.

Practice Summary

Peter Alexiadis' communications practice spans all aspects of regulation, policy and competition law affecting the communications sector, for both private companies and government institutions in Europe, Africa, Asia and the Middle East. His work for the sector is divided between advice for, and the defence of, private companies and counselling to government institutions. Peter has well over two decades of experience in conducting regulatory due diligence exercises in telecommunications sector mergers and in the drafting of regulatory overviews of the sector for IPOs. His expert opinions have often been cited in important regulatory decisions and court proceedings in many jurisdictions around the world, and he has addressed various international institutions and national parliaments on communications policy. In this regard, he has undertaken major telecommunications reform project work in countries such as Hungary, Greece and Cyprus, and has undertaken important regulatory advisory opinions inter alia for the National Regulatory Authorities of Cyprus, Portugal, Greece, Bahrain and Egypt.  He also has extensive experience in the review of State aids schemes affecting the electronic communications sector.

Peter has particular expertise in market definition and market power assessment under the EU Regulatory Framework for electronic communications networks and services, having been the principle draftsman for the Commission study exploring the new regulatory approach brought about under the Framework Directive, with extensive experience in advising both operators and regulators on market definition and market power issues under the Regulatory Framework established under that Directive (having conducted such analyses across EU jurisdictions such as Greece, Ireland, Portugal, Romania, Cyprus and Jordan, and having been project leader in the European Commission study which provided the analytical basis for the current EU Regulatory Framework for electronic communications networks and services).

He was also a project leader on a number of milestone European Commission studies relating to the development of new policy in the communications sector and indeed has also served as an external counsel to the Communications Unit at the European Commission's DG Competition for three years (1999 – 2002). He has worked extensively in regulatory policy matters across many jurisdictions, including: Ireland, Hungary, Greece, Romania, Portugal, Cyprus, Jordan, South Africa, Egypt, Bahrain, Thailand and San Marino. He has been the project leader in a number of landmark regulatory, competition and policy studies for the European Commission, including:

  • "Market Definitions for Regulatory Obligations in Communications Markets" (2002);
  • "Consumer Demand for Telecommunications Services and the Implications of the Convergence of Fixed and Mobile Networks for the Regulatory Framework for a Liberalised EU Market"(2000); and
  • "Adapting the EU Telecommunications Regulatory Framework to the Developing Multimedia Environment" (1997).

He has also been project leader for three European Commission studies in 2007-2008, entitled:

  • "Impact of Institutional Issues in the Review of the EU Framework for Electronic Communications";
  • "The Consistent Application of Regulatory Measures in the Area of Electronic Communications and its Impact in the Internal Market"; and
  • "The Future of Next Generation Access – an Analysis of Potential Remedies".

In recognition of his standing in the sector, Peter was appointed in 2007 as one of three trustees of the International Institute for Communications. Most recently, Peter was one of two international experts appointed by the Belgian Minister for Communications to select the President and the Board of the BIPT, Belgium's regulator in the communications sector.

Peter's competition practice focuses on merger control and joint ventures, actions under Article 102 TFEU (he acted as counsel to Netia and Tele 2 in the Commission Decision against Telekomunikacja Polska in June 2011, and to Si.mobil in its appeal to the General Court against the Commission's Decision in 2014, with both cases resulting in positive settlements for Netia and Si.Mobil), extensive advisory work on the EU's Broadband Guidelines including initial advisory work for the Greek government in the FTTH project, vertical distribution and licensing practices (both before the European Commission and before national competition and regulatory authorities), and the implementation of antitrust compliance programmes for  firms across a wide range of industries. He has particular expertise in the application of competition policy to regulated network industries and infrastructures. Peter was lead Competition counsel before the European Commission in two of the world's largest announced technology/telecommunications-related mergers, including Vodafone/Airtouch and WorldCom/Sprint, and has more recently been EU counsel in mergers involving Carlyle/Commscope, MCI/Sprint, Verizon/MCI, Epson/Sanyo, Seagate/Maxtor, Vivendi/Activision, Dolby/Doremi, and was the Greek government's external legal advisor in its review of the Cosmote/Germanos merger. He was also the briefing solicitor in the successful MCI vs. EC Commission appeal.

His intellectual property practice consists primarily in advising clients on the interface between intellectual property rights protection and competition law, especially as regards to innovative products and services. He was one of a handful of European legal experts to be invited by the United States' DoJ and FTC in May 2002 to give testimony on Hearings on "The Antitrust and Intellectual Property Interface" in Washington DC.
