Thorsten Mäger - Hengeler Mueller

Within: Antitrust

Recognised for being ‘unparalleled in antitrust law’, Hengeler Mueller offers ‘plenty of experience and excellent guidance’ for a broad client portfolio, which includes renowned German and international companies in equal measure. One area of specialism is fine proceedings which often have an international component. Markus Röhrig represented Japanese company Calsonic Kansei in EU fine proceedings relating to vehicle air-conditioning and engine cooling systems. The ‘pragmatic’ Thorsten Mäger succeeded in gaining full immunity from fines for MAN in connection with lorry antitrust proceedings on the basis of a leniency application, and the instruction still includes defence against claims for damages within the EU and beyond. It also defends Jacobs Douwe Egberts against claims for damages. The ‘very experienced’ Christoph Stadler and Thomas Paul defend the client against claims of the insolvency administrator of Schlecker. Flagship instructions in merger control law include acting for Knorr-Bremse in phase-II proceedings related to the takeover bid for Haldex, as well as advising Carl Zeiss Vision, as an intervening party, on the proposed merger between Essilor and Luxottica. Internal investigations are another strength and the group advises the Bosch Group on emissions with regard to diesel vehicles. Ralf Willer, who specialises in dispute settlement, was made counsel.
