Key legal question
Whether the complaint in public law matters was admissible despite no general statutory entitlement to a residence permit.
Extracted holding
The complaint was only admissible insofar as the applicant could rely on a special entitlement, here Art. 8 ECHR and Art. 13 BV.
Extracted reasoning
Under the former foreign nationals law, residence permits were discretionary absent a special federal or treaty-based right; a claim could nonetheless arise from family life protection.
