Partner
Bar admission Paris
Matthieu co-heads the firm’s civil, commercial and stock market litigation team.
He advises French and international companies, directors and shareholders before civil, commercial and criminal courts, as well as regulatory authorities such as the French stock market authority (AMF), in disputes relating to mergers and acquisitions, takeover bids and post-sale or shareholder disputes. He also works on ESG litigation, dealing with issues of corporate and managerial liability.
Matthieu has developed recognized experience in complex litigation involving major legal, financial and reputational issues, combining his legal skills and judicial experience with those of the firm’s various departments, in particular when faced with class actions, shareholder activism or litigation combining civil proceedings with criminal or AMF proceedings. He also works on alternative dispute resolution procedures (mediation and arbitration).
He has won the pleading competition organized by the Paris Bar and, as such, has been entrusted with emergency criminal defense work. He lectures at the Paris Bar School, the French National School for Magistrates, Sciences Po Paris and HEAD, where he created the legal writing workshops and the first pro bono business law clinic for start-up entrepreneurs. He has also been involved in the development of an artificial intelligence system applied to business litigation.
Matthieu is regularly ranked as one of the top business litigation specialists in leading directories such as Chambers and Legal 500 which describe him as one of the “leading lawyers in the market” in stock exchange litigation, commercial litigation and corporate law.
