Kernrechtsfrage
Whether the subsidiary constitutional complaint was admissible despite no enforceable right to the residence permits.
Extrahierter Entscheid
The complaint was admissible only to the limited extent that formal rights of party could be invoked, not on the merits.
Extrahierte Begründung
No federal or international right to the permits existed, so ordinary public-law appeal was unavailable; without a legally protected position, the appellants lacked standing on the merits.
