Questione giuridica chiave
Whether the appeal against the BVGer interim order was sufficiently reasoned under Art. 42 BGG.
Decisione estratta
The appeal did not address the challenged cost-advance order and therefore lacked a sufficient, case-specific reasoning.
Motivazione estratta
The appellant argued only the underlying VAT security issue and did not engage with the reasons for the cost advance; the pleading requirements were therefore not met.
