Question juridique clé
Whether the appellant’s right to be heard was violated by applying Belgian law to the donation issue
Solution extraite
No. The applicable law had already been disputed in the proceedings, so applying Belgian law was not unforeseeable and required no separate hearing.
Motifs extraits
The right to be heard covers unexpected legal bases only. Since the parties had already debated whether Belgian or French law applied, the cantonal court’s use of Belgian law was foreseeable.
