Question juridique clé
Whether the constitutional complaint could seek a reforming order fixing maintenance amounts
Solution extraite
The complaint was admissible only as a cassatory remedy; the request for the Federal Court to set maintenance itself was inadmissible.
Motifs extraits
A staatsrechtliche Beschwerde is, save exceptions not relevant here, purely cassatory, so the Federal Court may only annul the cantonal decision and not substitute its own maintenance determination.
