Peter joins from Clifford Chance (Paris) where he spent seventeen years in the firm's International Arbitration Group representing clients across Europe, Asia and the Gulf, particularly in the construction and energy sectors. During that time, Peter was involved in a number of highly complex disputes, including investment treaty arbitrations.
Peter is regularly appointed as an arbitrator and a Board member of the Arbitration Association in Paris which promotes the city as a seat for international arbitration. He is also a lecturer at Versailles University.
Peter's role will focus on International Arbitration in the Infrastructure and Energy & Natural Resources sectors, in particular Liquefied Natural Gas (LNG), power and major civil infrastructure projects.
Peter will join Frédéric Gillion as an integral part of Pinsent Masons’ construction and arbitration team. Frédéric joined the firm at the beginning of the year from construction law specialist Fenwick Elliott where he was a partner. Peter's skills, along with Frédéric's construction expertise, will strengthen Pinsent Masons' dedicated construction arbitration team in Paris and allow the firm to continue to grow its already impressive credentials acting on infrastructure and energy projects in Africa.
Richard Foley, Head of Construction Advisory & Disputes at Pinsent Masons, says:
"Peter joins Pinsent Masons at a very exciting time. We have a market leading reputation as construction arbitration specialists and are seeing significant growth at the moment, especially in Africa for oil & gas, mining and civil infrastructure projects. Peter's appointment in the Paris team will further strengthen the firm's international arbitration capabilities in that market.
Christoph Maurer, Head of Pinsent Masons' Paris office, says:
"We are pleased to be welcoming Peter to the Pinsent Masons team in France. Paris is not only one of the most significant arbitration centres in the world, but also a key gateway for those doing business in Africa. Peter's appointment is a coup for us and adds to the significant capability that already exists in the firm in relation to disputes across the construction and energy sectors."
Rosher is the second appointment to Pinsent Masons' Paris office this month after the firm announced that it would be establishing a French Tax practice following the appointment of former Slaughter & May and Landwell (PwC) lawyer Eugénie Berthet.
