Key legal question
Whether the public-law appeal against the expulsion decision was admissible in part.
Extracted holding
The appeal was admissible in principle, but not to the extent it sought annulment of the replaced cantonal decisions.
Extracted reasoning
The Federal Supreme Court had jurisdiction over cantonal final expulsion decisions under former aliens law; however, due to the devolutive effect, only the administrative court judgment could be challenged, not the earlier cantonal decisions.
