Questione giuridica chiave
Whether the federal appeal satisfied the formal requirements of Art. 42 BGG within the appeal period.
Decisione estratta
No. The filing contained no sufficient reasoning showing how the challenged decision violated federal law, and no timely supplemental brief was filed.
Motivazione estratta
Under Art. 100(1) and Art. 42(1)-(2) BGG, an appeal must be filed within 30 days and must set out requests and reasons in concise form. The letter of 25 March 2009 merely announced a later substantiated submission.
