Kernrechtsfrage
Whether a wage difference based on sex was credibly shown, shifting the burden to the employer.
Extrahierter Entscheid
Yes. A wage-based unequal treatment on account of sex was made credible, so the employer had to prove that the remuneration was non-discriminatory.
Extrahierte Begründung
Where unequal pay by gender is plausibly substantiated, the employer bears the burden of showing objective, non-discriminatory reasons for the salary system.
