Sylvain Justier, who holds a DJCE-DESS in Business Law (post-graduate degree) from Rennes I University, started his career at CMS Bureau Francis Lefebvre in January 2001 in the Europe, Competition and Economic Regulations team, of which he became manager in 2006. In 2007, he joined the Antitrust and Regulatory practice of White & Case LLP.
Specialised in competition law, he has also developed a recognised expertise in telecommunication and new technologies law, sectors in which he frequently assists major internet and mobile telephone operators on all the issues they encounter: interconnection and access to fixed and mobile networks, allocation of frequency bands, operator cooperation, etc.
For instance, he assisted various operators wishing to become MVNO, by helping them in the negotiations with their host operators and by representing them in their dispute resolution proceedings. He also led various actions before the competition authorities, dealing with practices jeopardising the competitive development of the sector, as well as before the commercial courts, to obtain damages for the prejudice suffered by his clients (private enforcement action, one of which led to the highest indemnity sentence ever held to this day in the new technologies sector – € 15 million).
Sylvain Justier also frequently acts in the energy sector (assistance with the development of wind energy or photovoltaic projects, drafting and negotiation of gas and electricity purchase agreement, access to network issues, etc.) and in the media sector (including access to data/contents).
Sylvain Justier is also experienced in distribution law (commercial policies, franchise networks, commission-based affiliation, commercial agency agreements) and in consumer law, area in which he has addressed the court in more than 10 comparative advertising cases.
Sylvain Justier frequently takes part in major conferences dedicated to these sectors and is the author of many articles.
"Sylvain Justier gains plaudits for his recent work, and one client states: 'He thinks outside the box and goes further than the questions we ask.'"
(Chambers Europe 2013, Competition/European Law)
"Sylvain Justier is celebrated for his strong work in the telecoms sector. Clients say: 'He excels in combining antitrust expertise together with regulation rules to build his cases. He is seen as a persistent and skilled newcomer.'"
