Kernrechtsfrage
Whether the civil court is bound by the salary stated in the work authorization under Art. 9 OLE and Art. 342(2) CO.
Extrahierter Entscheid
Yes. The approved salary in the work authorization is binding on the civil court; a lower contractual salary is void to that extent.
Extrahierte Begründung
Art. 9 OLE has civil-law effect: once the administrative authorization is final, the employer must pay the approved remuneration and the judge may not depart from it on the basis of an individual agreement or tacit waiver.
