Questão jurídica principal
Whether the constitutional complaint against the cantonal judgment was admissible.
Decisão extraída
The complaint was inadmissible because the applicant lacked a legally protected interest and could not invoke a federal or international entitlement to a residence permit.
Fundamentação extraída
A constitutional complaint requires a legally protected interest under Art. 115(b) LTF; arbitrariness review alone does not create such standing.
