Question juridique clé
Whether the administrative law appeal was admissible despite the general rule excluding foreign police matters without a federal right.
Solution extraite
The appeal was admissible to the extent the appellant could invoke the free-movement agreement as a potential source of a residence right; the parallel public-law appeal was inadmissible as subsidiary.
Motifs extraits
EU/EFTA nationality could in principle found a residence claim under the agreement, so admissibility depended on whether the agreement actually conferred a right in the concrete case; that was a merits question.
