Questão jurídica principal
Whether the public-law appeal was admissible despite the foreigner-permit context.
Decisão extraída
The appeal was admissible because the applicant could invoke a potential right under Art. 42 LStr and, in principle, Art. 8 ECHR.
Fundamentação extraída
For admissibility, it was enough that federal or international law might confer a right; the court did not need to determine definitively whether the substantive conditions were met.
