Kernrechtsfrage
Whether the complaint was admissible and could rely on the FZA despite the parties not invoking it initially
Extrahierter Entscheid
The complaint was admissible because a potential claim under the FZA existed; the court could apply the FZA ex officio after giving the parties a chance to comment.
Extrahierte Begründung
For admissibility, it suffices that an FZA-based entitlement appears plausible. The spouse's EU nationality and worker status could found a derivative right for the family.
