Questão jurídica principal
How should the contractual condition for exercising the buyback right be interpreted?
Decisão extraída
The condition was to be interpreted subjectively as requiring the son to still personally run the farm, not to exclude every operational change or third-party use of individual buildings.
Fundamentação extraída
The cantonal court relied on the clear text and a witness statement showing the parties intended the farm to remain together and belong to the operator of the paternal farm. No serious reason justified departing from that text.
