Awards and citations

  • "Clifford Chance managed to balance the departure of former practice head Patrick Hubert and three of his associates to Orrick Rambaud Martel with the arrival of the ‘exceptional’ David Tayar, who ‘stands well above the rest of the pack’ and joined from Willkie Farr & Gallagher LLP; additionally, Katrin Schallenberg was promoted to the partnership. Along with numerous high-value merger control cases in the pharmaceutical and car rental sectors, the group is representing clients such as Teva, Ingram Micro and Volkswagen in antitrust investigations. Of counsel Michel Petite successfully obtained clearance with remedies in phase two proceedings before the European Commission on behalf of Airbus Safran Launchers with regards to its acquisition of Arianespace and Marie Pacaux is also a key contact."
