Key legal question
Whether the appeal had to be entered into despite the missing power of attorney being cured late.
Extracted holding
No. The defect was not remedied within the deadline, so the appeal could not be considered.
Extracted reasoning
Under Art. 42 para. 5 BGG, a missing power of attorney must be cured within the set period under pain of non-entry. The submitted proxy was demonstrably deposited after the deadline of 22 February 2010, so the condition was not met.
