Kernrechtsfrage
Whether the non-compete clause from the original employment contract remained in force after later addenda that did not mention it
Extrahierter Entscheid
The later addendum was interpreted as having replaced prior addenda, and the omission of the non-compete clause amounted to a qualified silence leading to its implied cancellation.
Extrahierte Begründung
Applying the trust principle, the court found no proven mutual subjective intent to keep the clause alive. The burden of proving a contrary shared intent lay on the employer, and the evidence did not show that both parties still regarded the non-compete as valid.
