Question juridique clé
Whether the cantonal court committed a formal denial of justice by failing to decide on the husband's appeal regarding provisional maintenance
Solution extraite
Yes. Because provisional measures remain in force until the divorce or separation proceedings are finally resolved, the court had to decide whether the maintenance order should be modified.
Motifs extraits
A court commits formal denial of justice when it unlawfully refuses to rule on a matter within its competence. The existence of pending main claims did not remove the duty to examine the request to suppress maintenance, since provisional measures survive until final resolution and may be modified during the proceedings.
