Key legal question
Whether the public-law appeal against the cantonal judgment was admissible
Extracted holding
The public-law appeal was admissible because the applicants could potentially derive a residence right from Swiss and EU law.
Extracted reasoning
A possible right under Art. 42 LEtr and Art. 7 let. d ALCP in relation to Annex I made Art. 83 let. c ch. 2 LTF inapplicable.
