Whether the appeal satisfied the formal requirements of signature, grounds, conclusions, and proof of representation.
The appeal did not meet the mandatory formal requirements and the defects were not remedied within the time limit.
The filing contained only an objection to the challenged decision, without any reasons; it was unsigned and lacked a power of attorney. After being invited to regularize the filing and warned of the consequences, neither the representative nor the appellant responded, so the appeal was deemed withdrawn and therefore inadmissible.
