Kernrechtsfrage
Whether the appeal was filed within the statutory 30-day time limit.
Extrahierter Entscheid
The time limit expired on 2011-04-06, so the filing dated 2011-03-17 did not cure the later failure to submit a proper appeal.
Extrahierte Begründung
The appealed decision was allegedly received on 2011-03-07; the 30-day period began the next day and ended on 2011-04-06. No further brief was filed after that date.
