Questão jurídica principal
Whether the employee's new earnings from a job in Germany had to be offset against the salary claim against ETH Zürich.
Decisão extraída
Yes. The offset was limited to the period of double income and was compatible with federal law.
Fundamentação extraída
The court applied Art. 6(2) BPG in conjunction with Art. 337c(2) OR by analogy. Since the dismissal was declared void too late for reinstatement and the employee had already taken new employment, the new earnings had to be credited for the overlapping period.
