Question juridique clé
Whether the filing could be treated as an ordinary public-law appeal or only as a subsidiary constitutional complaint
Solution extraite
It could not be heard as an ordinary public-law appeal because the case concerned a foreigner's permit for which federal or international law conferred no entitlement; it was treated as a subsidiary constitutional complaint.
Motifs extraits
Art. 27 LEtr is discretionary and does not grant a right to the permit, so Art. 83 let. c ch. 2 LTF barred the public-law appeal.
