Key legal question
Whether an appeal filed with an incompetent cantonal authority is validly lodged in time.
Extracted holding
If an appeal is submitted to an incompetent cantonal authority, it must be forwarded ex officio to the competent instance, and the filing date counts as the date of appeal.
Extracted reasoning
The decision relies on settled cantonal administrative practice requiring ex officio transmission to the competent authority and preserving the original filing date.
