Key legal question
Whether the appellant had a potential right to a residence permit allowing public-law appeal admissibility.
Extracted holding
A potential right under Art. 8 ECHR/Art. 13 Cst. was not clearly excluded at admissibility stage, so the public-law appeal path remained open.
Extracted reasoning
The Court noted the restrictive case law on family reunification with adult children but left the question open because the appeal would fail on the merits in any event.
