Questão jurídica principal
Whether the shareholder non-compete clause was valid under Swiss law.
Decisão extraída
The clause was valid; it did not exceed the limits of contractual freedom and was not contrary to public policy or sham.
Fundamentação extraída
A shareholder agreement may contain a non-compete clause. Under Art. 27(2) CC, a restriction is excessive only if it eliminates economic freedom or places the obligor at the mercy of the other party. Given the clause's limited scope, the 50 km radius and five-year duration were not excessive in the circumstances.
