1 specialist practice area in Competition & European Union

Competition and regulatory authorities now possess far-reaching powers to investigate companies and commercial arrangements, prohibit M&A deals, force divestment of merged businesses, review markets and impose penalties or the recovery of illegal aids. There is the additional risk of private enforcement such as substantial (follow-on) antitrust damages claims. Being compliant and implementing effective risk mitigation strategies is key. We focus not only on problem solving but also on how you can avoid problems in the first place.

Our large team of competition lawyers has extensive experience in helping navigate these difficult paths so that you can focus on your business. We have in-depth knowledge of competition rules across different countries and markets.

We act for public and private clients in the following areas among others: competition law (abuses of dominant position, cartels, mergers), state aid, EU Litigation, Liberalisation (Energy, transports, Handling, Telecommunications and Utilities), EU Freedoms, Contracts with the European Institutions and European structural funds.

Our team has unrivalled experience, at both European & national level, in these challenging practice areas through regular notifications or complaints to the European Commission or the Belgian Competition Authority or through litigation before the European Courts.

We have advised clients from a wide variety of sectors on regulatory and competition issues, including:

  • Public authorities and public companies
  • Airports and airlines
  • Retail
  • Banks and financial institutions
  • Utility companies (electricity, gas, water)
  • Chemicals and pharmaceuticals
  • Telecommunications
  • Logistics and transports
  • Aerospace
  • European and national associations of undertakings

The CMS Competition Group is one of the largest competition teams in Europe and at the same time one of the most widespread. We offer a one-stop-shop solution to clients for all their competition law needs across Europe and beyond. Our sector approach helps us understand your business environment and get to grips with your issues.
