Peers and clients say: 

“Lukas is a very present antitrust lawyer and a rising star among cartel damages lawyers.”

“He is able to understand even extremely complex and difficult facts quickly which allows him to provide an appropriate solution.”

“Lukas is an outstanding lawyer who never loses the focus on what matters for the client.”

“Lukas impresses with his ability to think out of the box and find new arguments and approaches to a matter. His ability to precisely position the right arguments, to investigate in detail and understand complex business relationships in a really short time have impressed me most.”

“He has proven smart strategical litigation skills, always keeping an eye open for beneficial settlement opportunities.”


Lukas advises on all matters of European and German competition law. He represents clients before the German Federal Cartel Office, the European Commission as well as the German and European courts. His practice focuses on merger control, cartel and abuse of dominance cases, litigation before German courts, and compliance questions.

Currently, Lukas is acting on several high-profile cartel damages actions. He is defending a truck manufacturer in numerous lawsuits related to the trucks case and consumer goods manufacturers in damages proceedings related to the drugstore articles (KWR), consumer goods (HEMA) and consumer detergents cases.

He equally has a very active merger control practice, regularly representing clients in merger reviews before the German and European authorities as well as coordinating merger filings worldwide. His recent experience includes transactions in the chemical, energy, retail, real estate and steel industries.

Lukas’ recent work also includes defending a company in an ongoing cartel investigation by the European Commission and advising several e-commerce platforms on their competition law compliance.

Lukas regularly speaks at conferences and publishes on competition law issues. One of his articles (on an aspect of international merger control) won a Concurrences Antitrust Writing Award. In 2017, he spent six months on secondment to Allen & Overy's US antitrust practice group in New York and Washington, DC. Apart from his native German, he speaks fluent English, French and Spanish.

Allen & Overy's global antitrust and competition practice comprises over 120 specialists operating across APAC, Europe and North America. The practice advises corporate clients and financial institutions on their global antitrust transactions, policies, litigation and regulatory strategies, and regularly acts on some of the highest-profile and most complex cases in the market.
