Key legal question
Whether the federal appeal was open as an ordinary public-law appeal or only as a subsidiary constitutional complaint.
Extracted holding
Because the case concerned ordinary naturalization, the ordinary public-law appeal was excluded and the filing had to be treated as a subsidiary constitutional complaint.
Extracted reasoning
Art. 83 let. b LTF excludes the public-law appeal for ordinary naturalization matters; the appellant therefore could proceed only under Arts. 113 ss LTF and had standing under Art. 115 LTF.
