A Norwegian court has rejected a bid by dissident family members to open the company books of the holding company behind Oslo-listed Wilh Wilhelmsen.

The ruling by the Ringerike, Asker, and Baerum District Court is a victory for Wilh Wilhelmsen chief executive Thomas Wilhelmsen over an alliance of family members. His cousin Pontine Paus' Starship Investments is the formal plaintiff, but Starship's defeat is in practical terms a defeat for allied family interests.
