Question juridique clé
Whether the appeal in public law matters was admissible against the refusal of a residence permit.
Solution extraite
No admissible public-law appeal lay because no federal or international right to the permit was shown and the cantonal judicial instance had not been exhausted.
Motifs extraits
The appellant could not rely on an enforceable entitlement under Art. 83 lit. c no. 2 BGG; in any event, the matter had not first been brought before the competent cantonal court required by Art. 86 BGG.
