Questão jurídica principal
Whether the complaint against the order requiring a cost advance was admissible despite being directed against an interim decision.
Decisão extraída
The complaint was admissible because the cost-advance order could cause irreparable harm if non-payment led to non-entry.
Fundamentação extraída
An interim decision is separately appealable under Art. 93(1)(a) BGG when it may cause irreparable disadvantage; a threatened non-entry decision makes this the case.
