Kernrechtsfrage
Whether the bonus clause had to be completed by a hypothetical common intent because no performance agreement was reached
Extrahierter Entscheid
Yes. The parties never reached an actual agreement on the reserved performance plan, so the contract had to be supplemented according to the hypothetical intent of reasonable and honest contracting parties.
Extrahierte Begründung
The employer could not rely on the employee’s silence as consent to very general bonus criteria, especially since the employer had promised later mutual specification. The lower court could therefore infer that the parties would have continued the 50% fixed bonus solution.
