Question juridique clé
Whether the cantonal appeal procedure violated the right to be heard by using additional medical submissions without allowing comment.
Solution extraite
Yes. The appellant was not informed of the new dossier documents and had no opportunity to comment, so the right to be heard was violated.
Motifs extraits
The hearing right includes access to the file and the chance to respond to new decisive evidence; the cantonal court failed to notify the parties after adding the dentist's report and the EL office's response.
