Question juridique clé
Whether the appeal filed in German was admissible despite the procedural language requirement.
Solution extraite
No. Because the appellant did not refile in French within the set deadline, the appeal failed to meet an admissibility condition.
Motifs extraits
Under the Vaud Administrative Procedure Act, proceedings must be conducted in French and documents filed in another language must be returned with an invitation to submit them in the official language. Non-compliance after a warning makes the appeal inadmissible.
