Key legal question
Admissibility of the public-law appeal and subsidiary constitutional complaint
Extracted holding
The public-law appeal was admissible because a potential entitlement under former ANAG Art. 7 existed in principle; the subsidiary constitutional complaint was inadmissible because that remedy was subsidiary to the available appeal.
Extracted reasoning
The existence of a possible statutory residence entitlement meant the exclusion in Art. 83 lit. c ch. 2 BGG did not apply at the admissibility stage. Where the ordinary appeal is open, a parallel subsidiary constitutional complaint cannot be heard.
