Question juridique clé
Whether the municipality had standing to file the federal appeal against the cantonal judgment on residence deregistration.
Solution extraite
The municipality did not sufficiently show that it was affected in its own autonomy or that it had a specially protected public interest; therefore it could not appeal.
Motifs extraits
A municipality may invoke autonomy or, exceptionally, a protected public interest only if it is significantly affected in important public interests. Mere interest in correct application of the law or in knowing who resides on its territory is insufficient. The appellant also failed to meet the substantiation requirements for constitutional and arbitrariness complaints.
