Question juridique clé
Whether the appellant's right to be heard was violated by the cantonal procedure.
Solution extraite
No violation occurred because the appellant could file written submissions, inspect the file, and was given an oral hearing it later chose not to attend.
Motifs extraits
Article 29(2) of the Constitution guarantees an appropriate opportunity to be heard, not necessarily oral argument. The file access and the late written submission sufficed, and the missing hearing was attributable to the appellant.
