Questão jurídica principal
Whether the appeal against the interim order requiring an advance on costs was admissible.
Decisão extraída
The appeal was inadmissible because the pleading lacked a subject-related reasoned challenge to the advance-cost order.
Fundamentação extraída
Although such interim orders can in principle cause irreparable harm, the appellant had to address the only relevant question, namely the application of Art. 63(4) VwVG. Instead, it argued mainly about the merits of the underlying dispute and requested substantive relief beyond the permissible scope of review.
