Questão jurídica principal
Whether the filing of 4 August 2015 constituted an admissible appeal with an identifiable challenged decision.
Decisão extraída
The court could not determine that the filing was an appeal or against which decision it was directed; the appellant did not respond within the set deadline.
Fundamentação extraída
Under Art. 79 al. 1 LPA-VD, an appeal must be signed, state the conclusions and reasons, and include the challenged decision. The court's requests for clarification were returned undelivered, so the appellant was deemed not to have acted within the allotted time.
