Key legal question
Whether the public-law appeal was admissible against the cantonal court's non-entry decision in an immigration matter with no entitlement to a residence permit.
Extracted holding
The public-law appeal was inadmissible because the applicant had no enforceable right to the residence permit under federal or international law.
Extracted reasoning
A non-entry decision can only be challenged by public-law appeal if the underlying merits decision would itself be open to that remedy. Since the adult, unmarried appellant had no substantive entitlement, Art. 83 lit. c ch. 2 BGG barred the appeal.
