Questione giuridica chiave
Whether the appeal against the Federal Administrative Court's non-entry judgment was sufficiently reasoned under Art. 42 and Art. 108 BGG
Decisione estratta
The appeal lacked any adequate legal reasoning showing how the lower court violated federal law, so it was inadmissible in summary proceedings.
Motivazione estratta
The appellant did not explain why the statutory consequence of non-entry for non-payment of the advance under Art. 64(4) VwVG should not apply, nor how the lower court allegedly violated Swiss law.
