Question juridique clé
Whether the appeal could be heard despite the lack of consent from the appellant's legal representative.
Solution extraite
No. Because the legal representative expressly refused the required consent, the court could not enter into the appeal.
Motifs extraits
The court relied on the mandatory consent requirement for litigation by a person whose capacity had been provisionally restricted and who was represented by a guardian; the representative denied consent in writing, so the procedural prerequisite was missing.
