Question juridique clé
Whether the public-law appeal was admissible despite the immigration context and the requested verfassungsbeschwerde
Solution extraite
The public-law appeal was generally admissible based on an arguable Article 8 ECHR family-life claim; the subsidiary constitutional complaint was inadmissible.
Motifs extraits
A protected family life with settled-status family members was at least plausibly alleged, but a subsidiary constitutional complaint is excluded where ordinary public-law appeal is available.
