Antitrust, Competition and Trade Law Firm in Ukraine

We cover every area of Antitrust, Competition and Trade Law.

The CMS Antitrust, Competition and Trade (ACT) group is a part of one of the largest specialist competition and trade teams in the world. It consists of 225 CMS experts who advise clients in more than 40 countries worldwide on all ACT matters. 

Our specialists are competent in advising on merger control issues, general antitrust compliance, unfair competition matters, in supporting clients who are involved in open investigation proceedings, appealing decisions of the national competition authority in the court, and in providing any assistance required for resolving other competition-related questions.  Multi-jurisdictional experience gained through years of extensive practice of competition law worldwide allows our team to present the most complex cases in a precise and clear manner that the clients can easily understand.

Due to our size and wide footprint, we are able to deal with all ACT matters irrespective of their geographical dimension. Where necessary we cooperate with long established contacts from our wider network of law firms everywhere in the world.
Our Ukrainian team is advising on high-profile projects in various sectors of the economy, namely energy/oil & gas, fuel, life sciences, automotive, consumer products/FMCG, construction, digital economy,  telecommunications/media, transport and others. Being among market leaders in competition practice, our lawyers regularly take part in projects aimed at improving Ukrainian competition laws and regulations in part of aligning with EU acquis. They are also involved in helping the Ukrainian competition authority build its capacity. Also, we advise clients on all stages of obtaining Antimonopoly Committee of Ukraine (the AMCU) approval in state aid projects, including municipal projects backed by international financial institutions.

Our clients range from many large multinationals who frequently use our team as their ACT law firm of choice for the entire region (e.g., in Europe), to governments at all levels and also a high number of medium-sized companies. 

We use the most up-to-date technical and AI tools to support our business in Ukraine and other jurisdictions.

We hold a renowned annual EU competition law conference which has become a feature in the Brussels calendar.  We publish our regular case law updates on Ukrainian, European and international competition and trade developments at our Law Now service.  Our monthly EU law webinars are attended by in house counsel from around the world. And our group is steered, not just by a management committee of partners but also by an active associates’ group that keeps us innovating to serve clients.

CMS RRH Competition team made their mark at the international competition...
Last week (9 and 10 May 2024), our team represented CMS RRH Competition practice at the “Meet to Compete Competition Law and Policy Conference – Tools for New Rules” held in Opatija, Croatia. Dieter Zandler from CMS Austria, Marija Zrno Prošić, Dina Čeliković and Filip Bjelinski from Croatia, Srđan Janković and Maja Živanović (Serbia, Montenegro & North Macedonia), and Robert Kordić and Gašper Hajdu from Slovenia, together spent two wonderful days in interactive discussions with representatives of competition authorities, judges, attorneys, in-house lawyers, and other legal practitioners from all over the Europe. During the first day of the conference, discussions centered on topics including concentrations and FSR, the implications of the "effects-based approach," and recent developments in the Central and Southeast Europe (CEE & SEE) region. The team spent their first conference day pleasantly networking at the coffee break powered by CMS and in the evening at the cocktail and dinner with conference attendees. The second day of the conference was all about workshops covering topics such as exclusionary abuses of dominance, horizontal agreements and disagreements, RPM, etc. Our Marija Zrno Prošić led a focused workshop on the most common vertical restraints, using practical examples from the field and engaging with the audience through survey questions to enhance interaction and understanding. The audience reactions were very positive and discussions continued after the workshop. Overall, we were happy to have our close-nit competition team at this conference, as such events with regional outreach are crucial in fostering collaboration, enhance understanding of regulatory nuances, and promote best practices across different jurisdictions. About the Conference The Conference traditionally offers a platform for discussion about recent antitrust developments, with a particular focus on Central and Eastern Europe (CEE) and South-East Europe (SEE). The Conference is supported by the Croatian Competition Agency, universities and local organizations, with great speakers from the OECD, European Commission, universities, industry and regulators from the entire region and Europe.
