Question juridique clé
Whether a provisional maintenance order under Art. 145 ZGB can be challenged only within its provisional scope and reviewed ex tunc on appeal.
Solution extraite
The appeal could only concern the provisional measure itself; the definitive maintenance determination was not yet reviewable. The appellate court reviewed only the circumstances existing when the order was issued.
Motifs extraits
A measure under Art. 145 ZGB with provisional effect is comparable to an interim order. New developments after issuance are for the first-instance judge to consider, because he may amend the provisional order at any time. The appellate review is limited to whether the order was defensible on the basis of the facts known when made.
