Questione giuridica chiave
Whether the subsidiary constitutional complaint was admissible despite no enforceable right to the residence permits.
Decisione estratta
The complaint was admissible only to the limited extent that formal rights of party could be invoked, not on the merits.
Motivazione estratta
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.
