Data protection Tier 2

Advice in connection with internal investigations and with transactions constitute two other strategic pillars for the team, which often cooperates with the firm's US offices. Employment lawyer Paul Melot de Beauregard joined in May 2019 from McDermott Will & Emery Rechtsanwälte Steuerberater LLP and brought experience in data protection.
