Kernrechtsfrage
Whether the cantonal court correctly refused to enter into the appeal because no formal complaint was filed and the defect was not cured within the deadline.
Extrahierter Entscheid
Yes. The filing did not meet the statutory requirements, and the defect was not remedied within the extended time limit.
Extrahierte Begründung
The Federal Court agreed with the cantonal court that the submission of 21 June 2007 was insufficient under Art. 61 lit. b ATSG and remained uncorrected by 31 August 2007. The appellant's argument about her lawyer's conduct did not change this; the lawyer's behavior is attributable to her.
