Key legal question
Whether the appeal could be considered despite the missing power of attorney for counsel.
Extracted holding
No. Because the representative failed to cure the missing power of attorney within the set deadline, the filing was disregarded and the appeal was not entered into.
Extracted reasoning
Under Arts. 40(2) and 42(5) BGG, counsel must prove authority to act; if the defect is not remedied after warning, the submission remains unconsidered.
