Key legal question
Admissibility and standing for subsidiary constitutional complaint against naturalization refusal
Extracted holding
The subsidiary constitutional complaint was admissible, but the applicants lacked standing to challenge the refusal itself under arbitrariness review because they had no entitlement to naturalization.
Extracted reasoning
An ordinary appeal was excluded; constitutional rights could be invoked only to the extent protected by procedural guarantees or a specific fundamental right such as non-discrimination, not to contest the merits of a discretionary naturalization refusal.
