Questão jurídica principal
Whether the appeal by D. is admissible without a filed power of attorney.
Decisão extraída
The appeal is inadmissible as filed by D. because no power of attorney was produced for him within the deadline.
Fundamentação extraída
The court applied Art. 42 al. 5 LTF and noted that the missing authorization concerned only D., so the appeal could proceed only for the other appellants.
