Key legal question
Whether the complaint in public law was admissible despite the absence of a substantiated entitlement to a residence permit.
Extracted holding
No admissible public-law complaint lay because the appellant failed to show a plausible right to remain in Switzerland under federal or international law.
Extracted reasoning
The lifting of the entry ban did not create a residence right; the prior settlement permit had lapsed after the final revocation. Mere family ties and sporadic visits to the son did not sufficiently establish a current or new entitlement.
