Question juridique clé
Whether the cantonal court correctly denied sex discrimination in promotions before 1 January 1997.
Solution extraite
The cantonal judgment lacked essential factual findings on the comparability of the female employee and male colleagues; the matter had to be reassessed on remand.
Motifs extraits
A promotion-related comparison requires examining the colleagues' roles, classes, timing, and career development at the relevant time. The existing findings did not permit a reliable assessment of comparability or objective justification.
