Hendrik Riehmer, the former chief executive of Berenberg Bank, has formally escalated his legal challenge against the German financial regulator BaFin.

The lawsuit directly contests the extraordinary supervisory order that led to Riehmer’s removal from his post at the historic Hamburg institution.

The move marks a significant intensification of the conflict between the ousted executive and the supervisory authority.

By taking the matter to court, Riehmer is seeking to overturn the regulatory decision that stripped him of his duties, signaling that he does not accept the regulator’s assessment of his leadership.

This development adds a new layer of uncertainty to Berenberg Bank’s ongoing governance turmoil.

The bank has been navigating a period of instability following the regulator’s intervention, which was described as a sharp escalation in the oversight of the private bank.
