Questão jurídica principal
Whether the challenge to the revoked residence permit was still admissible after expiry of the permit.
Decisão extraída
The attack on the revocation itself was inadmissible because the permit had already expired; only the renewal issue could still be reviewed.
Fundamentação extraída
Without a current interest, the conditions of standing were no longer met. The court nevertheless addressed the matter because the cantonal decision also concerned renewal.
