Dr. Clemens E. Ziegler, LL.M. (Georgetown Univ.)
Recognised by Who’s Who Legal in 2018, 2019, 2020 and 2021 as a “future leader” in competition.
Clemens is committed to help businesses to quickly adapt to new requirements, to realise cost savings and other efficiencies. He provides business-oriented and pragmatic advice on minimising antitrust risk and on EU State aid law.
After over a decade in two major international law firms (Cleary Gottlieb and Hogan Lovells) in Brussels, with placements in Washington D.C. and Copenhagen, in 2019, Clemens started up his own boutique law firm in Brussels.
Advice in EU State aid law matters is a focus of Clemens’ practice. Further, not least due to his experience in competition compliance officer positions, Clemens also assists companies in managing antitrust risk, for instance by designing and implementing compliance programmes. He also advices on cooperation agreements and vertical agreements, including such with sustainability objectives. Clemens handles complex, multi-jurisdictional merger transactions and other types of regulatory filings. He also assists clients facing cartel investigations. More information on Clemens’ experience and the practice areas he covers can be accessed through the buttons below.
Clemens has particular experience in the maritime and energy industries, as well as in the automotive and telecommunications sectors. He has also worked in the area of pharmaceuticals and medical devices, in a number of industrial manufacturing sectors and areas of digitalised services.
Clemens regularly speaks and publishes on current developments in the areas of EU competition and State aid law. His native language is German; he is fluent in English, Italian and French and has a basic knowledge of Spanish and Dutch.
“Sources report that Clemens Ziegler has ‘great expertise in energy law, and particularly in state aid law.’ He is described as ‘diligent, dedicated and responsive, and possessing great integrity’, while remaining ‘calm under pressure’. He also brings ‘notable experience in German competition law matters.’”
