Gibson, Dunn & Crutcher’s Brussels office is the heart of our competition law practice in Europe.  We provide expert advice on all aspects of European Union and EU national competition law, including merger control, cartels, co-operative arrangements, abuse of dominance and State aids.  We work seamlessly with our Antitrust and Competition practices in the United States, Germany, France, the UK and Hong Kong, and are increasingly involved in follow-on and appellate litigation both before the EU and national courts. All of our lawyers are qualified and members of the bar in one or more Member States of the European Union.

Our internationally recognised EU antitrust practice covers a comprehensive range of matter types.  These include:

  • Merger clearances (both under the EU Merger Regulation and national merger rules)
  • Infringement actions concerning horizontal or vertical arrangements
  • Abuse of dominance complaints and investigations
  • Cartels
  • Online and offline distribution policies
  • Sector inquiries
  • State aids

Our EU practice has exceptional strength and experience across a wide range of sectors, and in particular in TMT and IT/Online, shipping, real estate, financial services, gaming/betting services, hotels and leisure, pharmaceuticals, and energy.  We also represent clients on other EU legal issues (including matters involving data protection, public procurement, and the freedom to provide goods and services throughout the EU) before EU Member State courts such as those of Germany, Spain, France, Belgium, Denmark and Greece.

Gibson Dunn’s Brussels team has deep experience of obtaining complex merger and joint venture clearances before the European Commission and EU national competition authorities.  This frequently involves conducting an analysis of merger filing requirements on a global scale.

The team in Brussels is an acknowledged market leader in representing parties involved in cartel investigations, including applications for immunity, leniency and settlement negotiations.  Our lawyers are frequently asked to advise on the implementation of antitrust compliance programs and the conduct of antitrust audits and training.  We have considerable experience in guiding parties and their trade associations through EU and national antitrust sector inquiries.

We also provide advice on EU competition law issues affecting clients’ strategic market interests or business models, particularly where these concern network industries.  Whether working on an innovative monopolisation defence or helping design the development of a sophisticated pan-European sales channel, we adopt forward-looking approaches that allow our clients to make informed choices at each critical stage of the relevant procedure.

As well as competition advocacy before the European Commission, we are increasingly involved in follow-on litigation, both before the EU Courts (on appeal from Decisions of the European Commission) and national courts (in relation to damages claims).
