Kernrechtsfrage
Whether the respondent remained contractually bound not to use the sign 'Swiss Alpine Military' after the cooperation ended.
Extrahierter Entscheid
The undertaking was construed as limited to the duration of the parties' business relationship and ended when that relationship ceased.
Extrahierte Begründung
Under the trust principle and the parties' circumstances, the agreement was tailored to the cooperation period; a gap had to be filled according to hypothetical intent, leading to termination of the contractual restraint with the end of the relationship.
