Questão jurídica principal
Whether the federal appeal against a cantonal naturalization decision was admissible
Decisão extraída
An ordinary public-law appeal was excluded; the filing could only be treated as a subsidiary constitutional complaint.
Fundamentação extraída
Art. 83 let. b LTF bars the ordinary appeal in naturalization matters. The cantonal administrative judgment was the final cantonal instance, so only the subsidiary constitutional complaint was available.
