Question juridique clé
Whether the administrative law appeal against refusal of a residence permit was admissible
Solution extraite
No statutory or treaty-based entitlement to the requested permit existed, including under the limitation ordinance or Article 8 ECHR; the appeal was therefore inadmissible.
Motifs extraits
The permit was discretionary, and the narrow family-life protection under Article 8 ECHR did not apply to an adult child absent a special dependency relationship. Prior residence status and past departure reasons were irrelevant to admissibility.
