EU law and competition law


Janson offers a large variety of services relating to antitrust/competition rules and EU law in general.

Janson represents national and international firms before the European Commission, the Court of Justice of the European Union, national competition authorities and courts.

Over the years, the firm has built a serious track record in high stake litigation involving critical State interests (e.g., in financial sector regarding the restructuring of Argentina’s sovereign debt, in energy, or in state aid cases).

Our services

Antitrust and Competition

Janson defends companies in all areas of antitrust/competition rules, in particular, in highly regulated industries, such as energy, finance, ICT or pharma.  The firm represented clients in cartel investigations, in abuse of dominance proceedings, in State aid  cases and in merger control processes.

Our firm has been involved in a number of cartel proceedings both at national and EU levels, and in major abuse of dominance investigations both as complainant and dominant company.  Janson defends clients in follow-on litigation.

Regarding State aids, our firm has obtained significant successes before national courts that enabled to restore the client’s position in a competitive market and maximize the financial outcome of the litigation.  This national strategy goes together with actions before the EU Commission that has exclusive jurisdiction to decide the compatibility of a State aid with the Internal Market.

In each competition case, the strategy is designed with the client from the very outset of the investigation and adjusted throughout the proceeding to minimize the risk exposure to fines and to protect the clients’ interest in a context of increasingly frequent follow-on litigation.

EU Law 

Beyond antitrust/competition, Janson advises its clients  on EU law and represents them in court litigation. 

Also, Janson assists other lawyers to navigate through EU law and build up new arguments in national procedures.  Often, EU law arguments have made possible radical changes in the dynamics at stake.

The firm guides its clients on the EU legal regime applicable to highly regulated industries such as energy, finance, pharma and ICT.  Janson’s expertise also covers various other fields of EU law such as trade policy, public procurement, distribution, intellectual property, EU funding and Common Agricultural Policy.

More generally, Janson’s assistance also relates to problematics on the functioning of the Internal Market – including the  four fundamental freedoms (the free movement of goods, services, capital and freedom of establishment) with their national implications –   and on the enforcement of EU law in the Member States (preliminary ruling to the EU Court of Justice, consistent interpretation of national law, minimum and maximum harmonization, direct effect, fundamental rights, role of national courts in the enforcement of EU law, Member States liability, action for annulment, action for failure to act, action for interim relief etc.).
