In 2007, philanthropist Christof Engelhorn pledged, through a Bermuda-based trust fund, 120 million Swiss francs (roughly $131 million) for the construction of a new adjustable opera/concert venue called the Salle Modulable for the Lucerne Festival. Since Engelhorn’s death in 2010, the trust has refused to honor the pledge, maintaining that it was not formally contracted. The Lucerners sued, and the case has now gone to trial in a Bermuda court.
