Question juridique clé
Whether late-filed exhibits XVII and XVIII were admissible
Solution extraite
They were inadmissible because new exhibits in appeal had to be filed with the submissions they supported; the complaint did not show a constitutional violation.
Motifs extraits
The challenge was insufficiently reasoned as to cantonal procedural law, and the alleged evidentiary issue did not establish a violation of the right to be heard because the fact at issue was already apparent from first-instance evidence.
