Questão jurídica principal
Whether the public-law appeal against revocation of a settlement permit was admissible.
Decisão extraída
The appeal was admissible because revocation of a settlement permit can in principle be challenged before the Federal Supreme Court, and the filing satisfied the formal requirements.
Fundamentação extraída
A settlement permit normally gives a right to renewal; the cantonal judgment was final and issued by a higher cantonal court, and the appellant had standing.
