Question juridique clé
Whether the appeal was admissible despite the expiry of the residence permit and the lack of current legal interest.
Solution extraite
The appellant no longer had a current protected interest in setting aside the cantonal decision, because the permit had already expired by the time the appeal was filed.
Motifs extraits
The challenged decision concerned only the revocation of an already expired permit. The cantonal judgment could not additionally be treated as a decision refusing renewal under the new aliens law, since the lower court expressly applied the old law and excluded the new one.
