Question juridique clé
Whether the public-law appeal was admissible because the appellant had a legal claim to a residence permit under Art. 8 ECHR.
Solution extraite
No sufficiently substantiated legal entitlement was shown; family life with adult parents did not establish an enforceable permit claim, and no special dependency was proven.
Motifs extraits
The appellant was adult, had lived separately from his parents for years, had stayed in Ghana for 18 months without them, and financial dependence alone is insufficient. His private-life ties in Switzerland also did not create a claim.
