Kernrechtsfrage
Whether the repurchase duty was void or adjustable under abuse of rights / clausula rebus sic stantibus after the company's insolvency and share devaluation.
Extrahierter Entscheid
No. The value change was foreseeable, the contract did not provide for price adjustment or lapse upon bankruptcy, and there was no basis for judicial adaptation or abuse of rights.
Extrahierte Begründung
A substantial and extraordinary, unforeseeable change of circumstances is required; foreseeable depreciation of the shares excludes reliance on clausula rebus sic stantibus. The parties allocated the risks and chances to the plaintiff by the clear wording of the agreement.
