Question juridique clé
Whether the public-law appeal was admissible despite the expired permit and foreigner-law exceptions.
Solution extraite
The appeal was admissible insofar as it challenged the refusal to renew the residence permit, because the appellant could invoke rights under the free-movement agreement.
Motifs extraits
Although a revoked permit that has already expired cannot be attacked as such, refusal of renewal remains reviewable where the applicant relies on treaty-based residence rights.
