Sylvie is further known in the French market as a leading toxic tort / mass litigation lawyer. As such, she has been involved in most pro-company case law rendered in recent years, notably in asbestos-related cases, with some cases mentioned in the French Civil and Social Security Codes because of the significant reversal in case law they represent.
