Questione giuridica chiave
Whether the public law appeal was admissible against revocation of the residence permit and refusal of a settlement permit.
Decisione estratta
The appeal was admissible only as to the revocation of the residence permit derived from the marriage, but not as to a discretionary residence permit; the constitutional appeal was therefore inadmissible.
Motivazione estratta
A derived right existed in principle under the free-movement rules during the formal marriage, so the challenge to revocation fell within the public law appeal. By contrast, no enforceable right existed to a discretionary permit under Art. 4 LSEE.
