Question juridique clé
Whether municipality A.___ had standing to appeal the authorization of out-of-district school attendance.
Solution extraite
The municipality lacked a sufficiently protected communal interest and could not rely on general financial effects; the appeal was inadmissible.
Motifs extraits
Municipal standing is restrictive. No further municipal autonomy exists regarding out-of-district school attendance, and the loss of a cantonal per-pupil lump sum is not enough to create a protected interest.
