Key legal question
Whether the appeal against the Federal Administrative Court's order requiring a cost advance was sufficiently reasoned.
Extracted holding
No; the appeal did not address the legal requirements for the cost advance and therefore did not show any violation of federal law.
Extracted reasoning
Under Art. 42 and 95 BGG, the appeal must specifically explain how the challenged act violates federal law. The appellant only argued that the tax authority had acted wrongly, which did not engage with Art. 63(4) VwVG or the discretion to waive a advance only for special reasons.
