Question juridique clé
Whether the public-law appeal was admissible in a foreign nationals residence-permit case without a statutory or treaty-based entitlement.
Solution extraite
No such entitlement existed, so the public-law appeal was unavailable under Art. 83(c)(2) LTF.
Motifs extraits
The applicant did not assert any right to stay in Switzerland under domestic law or an international treaty; therefore the Federal Supreme Court lacked admissibility for this remedy.
