Key legal question
Whether the appellants were entitled to bring a constitutional complaint on the merits despite no right to renewal of the residence permit.
Extracted holding
They lacked standing to challenge the refusal on the merits, but could raise only procedural rights violations such as denial of hearing.
Extracted reasoning
A foreigner without a residence-permit entitlement has no legal interest protected by Art. 88 OG as to the merits; only formal denial-of-justice claims are admissible.
