Competition & EU


Competition authorities have increasingly far-reaching powers to investigate mergers, markets, sectors, cartels, market conduct and commercial arrangements. You face an ever-increasing risk of regulatory intervention, significant penalties, damages litigation and criminal liability.

Our dedicated competition and regulatory experts in CEE, including former regulators, can advise you on the entire range of contentious and non-contentious competition law issues. We regularly advise clients on competition matters across multiple jurisdictions in CEE, working closely together, to deliver consistent and joined-up advice. We have a successful track record in representing clients before national authorities and courts, as well as the European Commission and courts.

Extremely thorough [and] deeply experienced in the field of competition.
Chambers Europe, 2019

We support clients on all their competition law needs: cartels, horizontal and vertical restraints, abuse of dominance, merger control, state aid, investigations and compliance, regulatory appeals, criminal liability, damages litigation, public procurement and consumer protection. Being compliant and implementing effective risk mitigation strategies is key.

Our large team of competition lawyers has extensive experience in helping navigate these challenges so that you can focus on your business. We have in-depth knowledge of competition rules across different countries and markets and use our sector approach to help us understand your business environment and get to grips with your issues.
