Question juridique clé
Whether the cantonal court arbitrarily rejected reopening of the appeal proceedings because the alleged timely filing of the appeal was not proven.
Solution extraite
The rejection was not arbitrary; the court could doubt the appellant's account and find the new fact unproven.
Motifs extraits
Even if the mailbox was emptied earlier than indicated, that did not prove the appellant actually deposited the filing then. The postal stamp and surrounding circumstances contradicted his version, so the court did not act in an obviously untenable manner.
