Question juridique clé
Whether the public law appeal against the refusal to extend the residence permit was admissible
Solution extraite
It was inadmissible because the appellant did not credibly assert any entitlement under federal law or an international treaty.
Motifs extraits
In immigration matters, public law appeal is excluded where no enforceable right to the permit exists. The appellant failed to show a plausible legal basis, so the Court could not enter into the merits.
