Question juridique clé
Whether the Geneva court sufficiently reasoned its jurisdiction to order provisional maintenance under Art. 10 LDIP
Solution extraite
The cantonal judgment did not state which jurisprudential ground under Art. 10 LDIP justified jurisdiction for maintenance matters, so the right to a reasoned decision was violated.
Motifs extraits
The court explained jurisdiction only for custody/contact issues, not for the spouse and child maintenance contribution; without a subsumption under one of the five Art. 10 LDIP scenarios, the parties could not understand or challenge the ruling.
