Questione giuridica chiave
Whether the administrative appeals were admissible despite expiry of the residence permits.
Decisione estratta
The challenges against the revocation as such were inadmissible for lack of current practical interest, but the complaint against the refusal to renew the mother's permit remained admissible because she had a statutory entitlement under Art. 7 LDDS.
Motivazione estratta
The permits had expired before the federal appeals were filed, eliminating current interest as to revocation. By contrast, Art. 7 LDDS gives the foreign spouse of a Swiss citizen a right to renewal, so the refusal of renewal could be reviewed; the child's position depended on the mother's.
