Questão jurídica principal
Whether the constitutional complaint against the refusal to extend the residence permit was admissible despite no enforceable entitlement to the permit.
Decisão extraída
The complaint was inadmissible because no federal-law or treaty-based right to the permit existed, so the appellants lacked legally protected interest to invoke arbitrariness.
Fundamentação extraída
In immigration matters, administrative judicial review is excluded where no federal entitlement to the permit exists. Without such a claim, a constitutional complaint attacking the merits is also unavailable; only procedural rights amounting to a formal denial of justice could be raised, and none were asserted.
