Questão jurídica principal
Whether the federal complaint against refusal to renew the residence permit was admissible.
Decisão extraída
It was inadmissible because no federal or international right to the requested permit was shown.
Fundamentação extraída
Complaints are barred under Art. 83 lit. c BGG for permits without a legal entitlement; the applicant did not establish a claim, and discretionary/hardship-based residence permits confer no right.
